A clinical educator at a skilled nursing facility is reviewing the admission assessments completed by newly hired nurses. Which of the following documented findings for a 77-year-old client should the educator identify as expected physiological adaptations of the normal aging process? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Thinning of the epidermal and dermal layers resulting in translucent, fragile skin.; Decreased vital capacity and a less vigorous, diminished cough reflex.; Gradual decrease in overall height accompanied by a reduction in lean skeletal muscle mass.

Answer

The expected physiological adaptations of normal aging are thinning of the skin layers, decreased vital capacity with a weakened cough reflex, and a gradual decrease in height and lean muscle mass.
Normal senescence involves predictable, progressive physiological declines across multiple body systems that occur over years or decades. The integumentary system gradually loses subcutaneous fat and structural integrity, resulting in thin, fragile skin. The respiratory system experiences decreased chest wall compliance and tissue elasticity, leading to reduced vital capacity and diminished airway clearance mechanisms. The musculoskeletal system slowly undergoes bone demineralization and sarcopenia, manifesting as decreased height and reduced muscle mass. These are expected, non-acute developmental changes.

Step-by-Step Solution

1
Analyze the clinical scenario and identify the specific task requested in the stem.
The nurse must differentiate normal, expected physiological aging (senescence) from acute pathological changes.
Older adults often present atypically, and confusing an acute pathological disease process with a normal aging change can delay life-saving clinical interventions.
2
Evaluate the options describing integumentary, respiratory, and musculoskeletal changes.
Identify thinning skin, decreased vital capacity, and height reduction as expected, gradual age-related physiological declines.
Cellular aging inevitably leads to decreased dermal thickness, loss of chest wall elasticity, progressive bone demineralization, and sarcopenia.
3
Evaluate the options describing cognitive, genitourinary, and acute respiratory status.
Recognize that sudden confusion, new-onset incontinence, and tachypnea with accessory muscle use are highly abnormal.
These findings represent potentially life-threatening acute conditions (e.g., delirium, severe infection, acute respiratory failure) that demand immediate medical prioritization, rather than being dismissed as expected aging.

Question 2682Question →

A nurse is caring for a client in the final stages of terminal lung cancer. The client is unresponsive and exhibiting a Cheyne-Stokes respiratory pattern. The client's spouse is crying at the bedside and asks the nurse, "I know he is dying, but I just want him to wake up and talk to me one last time. Should I try to wake him?" Which of the following is the most appropriate response by the nurse?

Show answer & explanation

Answer: It is incredibly difficult to see him like this. Even though he cannot respond, hearing is often the last sense to fade, so I encourage you to keep talking to him.

Answer

The most appropriate response validates the spouse's feelings and provides accurate education that hearing is often the last sense to fade, encouraging continued communication.
The correct response directly validates the spouse's feelings of distress while providing accurate, comforting education about the dying process. Hearing is widely considered the last sense to be lost, so encouraging the family to continue speaking to the client promotes emotional connection and psychological comfort for both the client and the family without causing physical distress or agitation to the client.

Step-by-Step Solution

1
Analyze the spouse's statement and emotional state.
The spouse is experiencing anticipatory grief and a strong desire for connection, but lacks understanding of the physiological realities of the active dying phase.
Identifying the underlying emotion (grief) and knowledge deficit guides the selection of a therapeutic response.
2
Evaluate the proposed nursing responses against principles of therapeutic communication and palliative care.
The response must address the emotional pain directly (validation) and provide correct physiological context without causing harm to the client.
Therapeutic communication in end-of-life care requires presence, honesty, and empathy, avoiding false reassurance or avoidance.
3
Select the option that best combines emotional validation with appropriate palliative education.
The option encouraging the spouse to talk because hearing remains intact meets both criteria.
Hearing is widely recognized as the last sense lost during the dying process, allowing families a safe and meaningful way to connect without causing physical distress to the client.

Question 2683Question →

During a routine health maintenance visit, a clinic nurse evaluates a toddler who just turned two years old. Based on standard pediatric growth and development guidelines, which assessment findings indicate the client is achieving age-appropriate milestones? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Building a stable tower of six to seven blocks; Combining two to three words into short, meaningful phrases; Playing alongside other children with similar toys without interacting

Answer

The age-appropriate milestones for a 2-year-old include building a tower of six to seven blocks, combining two to three words into short phrases, and engaging in parallel play.
A 24-month-old toddler is expected to have the fine motor skills to build a tower of six to seven blocks. Their language development typically includes a vocabulary of approximately 300 words and the ability to combine two to three words into short phrases. Psychosocially, toddlers engage in parallel play, where they play alongside other children using similar toys but do not directly interact or cooperate.

Step-by-Step Solution

1
Identify the client's exact developmental age from the scenario.
The client is a toddler who is exactly two years old (24 months).
Developmental milestones are highly specific to chronological age and rapidly change between 12 and 48 months.
2
Evaluate the motor skill findings against expected 24-month milestones.
Building a tower of six to seven blocks is expected. Walking downstairs with alternating feet and copying a circle are too advanced (expected at 4 and 3 years, respectively).
Differentiating between toddler and preschool motor skills ensures accurate developmental screening.
3
Evaluate the language and psychosocial findings against expected 24-month milestones.
Using two- to three-word phrases and engaging in parallel play are expected. Cooperative play and sharing are too advanced (expected around 4 years).
Language rapidly expands at this age, and play transitions from solitary (infant) to parallel (toddler) before becoming associative and cooperative (preschooler).

Question 2684Question →

A community health nurse is conducting a health screening for a 25-year-old client who discloses the regular use of injectable anabolic-androgenic steroids for competitive bodybuilding. Which statements by the nurse are appropriate to promote harm reduction and health maintenance? Select all that apply.

Select all that apply

Show answer & explanation

Answer: It is important to have your blood pressure and lipid profile monitored regularly.; You should rotate your injection sites to prevent localized tissue damage and abscess formation.; You should use a fresh, sterile needle and syringe for every injection.

Answer

The correct statements emphasize using a fresh, sterile needle for every injection, rotating injection sites to prevent tissue damage, and regularly monitoring blood pressure and lipid profiles.
Harm reduction focuses on minimizing the negative physical and psychosocial impacts of high-risk behaviors, rather than demanding immediate abstinence. For a client using any injectable substance, utilizing sterile equipment and rotating injection sites are critical actions to prevent bloodborne infections and localized tissue necrosis. Furthermore, because anabolic steroids significantly increase the risk of hypertension and dyslipidemia, regular cardiovascular monitoring is an essential health maintenance strategy.

Step-by-Step Solution

1
Identify the client's specific high-risk behavior and the nursing goal.
The client is using injectable anabolic steroids. The primary nursing goal is to promote harm reduction and general health maintenance.
Establishing the goal provides a framework for evaluating which interventions are safe, therapeutic, and realistic.
2
Evaluate each nursing statement against the principles of harm reduction and therapeutic communication.
Statements advising sterile needle use and site rotation directly reduce physiological harm. The statement demanding immediate abstinence is non-therapeutic and blocks communication.
Harm reduction focuses on minimizing the negative impacts of behaviors without demanding immediate cessation, requiring a non-judgmental approach.
3
Analyze the physiological implications specific to anabolic steroid use.
Steroids cause cardiovascular risks (hypertension, dyslipidemia) validating the need for screening. They also suppress natural hormones, meaning abrupt cessation causes severe psychiatric and physical withdrawal.
Understanding the specific pathology of the substance ensures that education regarding monitoring and withdrawal is medically accurate.

Question 2685Question →

A client with a documented history of severe chronic obstructive pulmonary disease (COPD) is brought to the emergency department by a caregiver. The caregiver reports that the client has become increasingly lethargic and confused over the past four hours. The healthcare provider orders an arterial blood gas (ABG) analysis on room air. Which of the following ABG results indicates an acute loss of compensatory mechanisms requiring immediate airway management?

Show answer & explanation

Answer: pH 7.24, PaCO2PaCO_2 76 mm Hg, HCO3−HCO_3^- 29 mEq/L, PaO2PaO_2 52 mm Hg

Answer

The ABG result showing pH 7.24, PaCO2PaCO_2 76 mm Hg, HCO3−HCO_3^- 29 mEq/L, and PaO2PaO_2 52 mm Hg indicates an acute loss of compensatory mechanisms.
The correct answer demonstrates acute-on-chronic respiratory acidosis. The client's pH is significantly acidotic (7.24) combined with severe hypercapnia (PaCO2PaCO_2 76 mm Hg). While the bicarbonate (HCO3−HCO_3^-) is slightly elevated (29 mEq/L), reflecting underlying chronic compensation from long-standing COPD, it is entirely insufficient to buffer the acute spike in carbon dioxide. This uncompensated state, combined with the clinical presentation of lethargy and confusion, strongly suggests carbon dioxide narcosis and impending respiratory arrest.

Step-by-Step Solution

1
Analyze the client's clinical presentation and medical history.
The client has severe COPD (chronic CO2CO_2 retainer) and presents with new-onset lethargy and confusion.
Lethargy and confusion in a COPD client are classic signs of carbon dioxide narcosis, indicating an acute inability to ventilate adequately.
2
Evaluate the ABG options for signs of acute-on-chronic respiratory failure.
Identify the set of values showing a significantly acidotic pH and an acutely elevated PaCO2PaCO_2 that exceeds the buffering capacity of the chronically elevated HCO3−HCO_3^-.
A client with severe COPD typically operates in a state of fully compensated respiratory acidosis (normal pH, high PaCO2PaCO_2, high HCO3−HCO_3^-). An acute exacerbation causes a sudden spike in PaCO2PaCO_2, causing the pH to drop dramatically because the kidneys cannot increase HCO3−HCO_3^- fast enough to compensate.
3
Select the ABG matching the uncompensated acute decline.
The correct ABG shows a pH of 7.24 (acidemia), a PaCO2PaCO_2 of 76 mm Hg (severe hypercapnia), and an HCO3−HCO_3^- of 29 mEq/L (inadequate chronic compensation for the acute event).
This specific combination confirms a life-threatening respiratory failure requiring immediate intervention, distinguishing it from the client's expected baseline.

Question 2686Question →

A client with severe decompensated heart failure is admitted to the intensive care unit with a double-lumen peripherally inserted central catheter (PICC) in place. Lumen 1 is infusing continuous dobutamine, and Lumen 2 is infusing continuous 0.9%0.9\% sodium chloride. The healthcare provider prescribes stat intravenous (IV) furosemide, a continuous IV heparin infusion, and a scheduled dose of IV potassium chloride. Which actions by the nurse are appropriate? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Administer the stat IV furosemide through Lumen 2 after flushing the port with 0.9%0.9\% sodium chloride.; Verify the physical compatibility of the continuous heparin infusion with 0.9%0.9\% sodium chloride before connecting it to Lumen 2.; Evaluate the client's continuous electrocardiogram (ECG) rhythm and baseline serum creatinine prior to initiating the potassium chloride.

Answer

The nurse should administer the furosemide through Lumen 2 after flushing, verify the compatibility of heparin with the normal saline in Lumen 2, and evaluate the ECG rhythm and renal function before giving the potassium chloride.
Safe central line management and pharmacology principles require the nurse to protect dedicated lines for vasoactive infusions, thoroughly verify fluid compatibility before Y-site administration, flush lines adequately between intermittent medications, and apply rigorous monitoring and rate limits to high-alert electrolytes like potassium chloride.

Step-by-Step Solution

1
Analyze the critical nature of the existing infusions.
Identify that dobutamine (Lumen 1) is a life-sustaining vasoactive medication that cannot be paused or interrupted.
Maintaining hemodynamic stability is the highest priority in decompensated heart failure.
2
Evaluate compatibility constraints for the new prescriptions.
Determine that heparin and dobutamine are incompatible, so heparin cannot be infused via Lumen 1.
Mixing incompatible medications causes precipitation, risking embolism and altered drug efficacy.
3
Plan safe administration parameters for high-alert medications.
Recognize that IV potassium chloride requires strict rate limits (max 20 mEq/hr20\text{ mEq/hr} centrally) and pre-assessment of renal and cardiac status.
Rapid or unmonitored potassium administration can cause fatal cardiac arrhythmias.

Key Concept

Safe administration of parenteral therapies requires continuous maintenance of critical inotropes, strict verification of IV compatibility, and adherence to high-alert medication administration parameters.
Question 2687Question →

A public health nurse is designing a competency assessment for newly hired registered nurses regarding the epidemiological framework of disease prevention. Which of the following interventions should be identified as secondary prevention strategies? (Select all that apply.)

Select all that apply

Show answer & explanation

Answer: Screening a 50-year-old client for colorectal cancer using a fecal immunochemical test (FIT).; Obtaining a capillary blood sample to test for elevated lead levels in a 12-month-old infant.; Conducting routine blood pressure and body mass index (BMI) assessments for asymptomatic adults.

Answer

The correct secondary prevention strategies are: screening for colorectal cancer using a FIT, obtaining a capillary blood sample to test for lead levels, and conducting routine blood pressure and BMI assessments.
Secondary prevention focuses on the early detection, screening, and prompt intervention for asymptomatic diseases or conditions to halt their progression. This level of prevention includes screening tests and diagnostic procedures aimed at identifying health issues before they cause significant morbidity. Screening for colorectal cancer using a fecal immunochemical test (FIT), testing for elevated lead levels in an asymptomatic infant, and conducting routine blood pressure and BMI assessments all serve to detect hidden or early-stage health problems, allowing for timely and effective treatment.

Step-by-Step Solution

1
Analyze the question to determine the specific concept being evaluated.
The question requires identifying examples of secondary disease prevention strategies from a list of clinical interventions.
Differentiating the three levels of prevention (primary, secondary, tertiary) is necessary to correctly evaluate each option.
2
Recall the definitions for the epidemiological levels of prevention.
Primary prevention stops disease before it starts (health promotion). Secondary prevention focuses on early detection/screening of asymptomatic disease. Tertiary prevention manages established disease to prevent complications (rehabilitation).
Establishing clear clinical definitions provides the criteria needed to categorize each nursing action.
3
Categorize each given intervention based on the established definitions.
Folic acid (Primary); FIT testing (Secondary); Diabetic foot care (Tertiary); Lead screening (Secondary); Cardiac rehabilitation (Tertiary); BP/BMI checks (Secondary).
Systematically analyzing each scenario ensures that only the secondary prevention strategies are selected.

Key Concept

The epidemiological framework of disease prevention classifies interventions into primary (preventing disease occurrence), secondary (early detection and screening), and tertiary (management and complication prevention of established disease).
Question 2688Question →

A neonate born at 32 weeks gestation had a birth weight of 1800 g1800\text{ g}. On day 3 of life, the neonate's current weight is 1650 g1650\text{ g}. The healthcare provider prescribes a total daily fluid intake of 120 mL/kg/day120\text{ mL/kg/day} based on the neonate's current weight. The neonate is receiving the following therapies:

- Enteral formula feedings of 13 mL13\text{ mL} every 3 hours via orogastric tube.
- Intravenous (IV) ampicillin every 12 hours. Each antibiotic dose is diluted in 5 mL5\text{ mL} of normal saline.

The remaining fluid requirement will be administered as a continuous IV infusion of 10% dextrose in water (D10W). The antibiotic volume is included in the total daily fluid intake. What is the required infusion rate for the continuous D10W, in mL/hr\text{mL/hr}, to ensure the neonate receives exactly the prescribed total daily fluid intake? Record your answer using one decimal place.

Show answer & explanation

Answer: 3.5

Answer

The correct infusion rate is 3.5 mL/hr.
The correct rate of 3.5 mL/hr accurately accounts for the total daily fluid requirement based on the neonate's current weight, minus the fluids provided by enteral feedings and intermittent IV antibiotics.

Step-by-Step Solution

1
Convert the current weight to kilograms.
1650 g = 1.65 kg.
The fluid prescription is weight-based in kg, and the current weight must be used as prescribed.
2
Calculate the total daily fluid requirement.
1.65 kg × 120 mL/kg/day = 198 mL/day.
Determines the absolute total volume the neonate must receive in 24 hours.
3
Calculate the total daily enteral intake.
24 hours / 3 hours = 8 feeds/day. 8 feeds × 13 mL = 104 mL/day.
Accounts for all fluid provided via the gastrointestinal tract.
4
Calculate the total daily IV antibiotic volume.
24 hours / 12 hours = 2 doses/day. 2 doses × 5 mL = 10 mL/day.
Accounts for intermittent IV fluid administration that contributes to the total intake.
5
Calculate the remaining fluid needed.
198 mL - 104 mL - 10 mL = 84 mL/day.
Determines the balance of fluid that must be supplied exclusively by the continuous D10W infusion.
6
Calculate the hourly continuous infusion rate.
84 mL / 24 hours = 3.5 mL/hr.
IV pumps are programmed in mL/hr.

Key Concept

Neonatal fluid management requires synthesizing multiple intake sources (enteral feedings, intermittent IV medications) and calculating continuous IV rates based on the current daily weight to prevent dangerous fluid overload or dehydration.
Question 2689Question →

A client on a telemetry unit requires strict bed rest after undergoing a percutaneous coronary intervention via the right femoral artery. During the immediate post-procedure period, the client reports a mild lower back ache and needs personal hygiene care. Which nursing interventions are appropriate for this client? (Select all that apply.)

Select all that apply

Show answer & explanation

Answer: Maintain the right leg in a straight position while log-rolling the client to the left side for back care.; Instruct the client in deep breathing and guided imagery to help manage the back discomfort.; Apply a protective moisture barrier ointment to the sacral area after cleansing the skin.

Answer

The appropriate interventions include keeping the right leg straight while log-rolling to the left side, teaching relaxation techniques for comfort, and applying barrier cream to the sacrum.
Appropriate basic care for a client post-femoral catheterization involves adapting hygiene and comfort measures to strict positioning limits. The client must be log-rolled to the unaffected side while keeping the affected limb straight to prevent bleeding. Providing non-pharmacologic comfort and applying skin barrier cream are essential, safe nursing actions that maintain physiological integrity during bed rest.

Step-by-Step Solution

1
Analyze the client's current clinical constraints
The client has a right femoral artery puncture site, requiring strict bed rest with the right leg kept completely straight and the head of the bed elevated no more than 30 degrees.
To prevent bleeding or hematoma formation at the high-pressure arterial access site.
2
Evaluate hygiene interventions
Hygiene can be safely provided by log-rolling the client to the left (unaffected) side while ensuring the right leg remains extended. Barrier cream should be applied to protect the sacral skin from breakdown.
Basic care must be adapted to align with post-procedure mobility restrictions.
3
Evaluate pain management and assessment interventions
Non-pharmacologic methods like deep breathing should be used for comfort. The RN must personally assess the back pain instead of delegating it, as it could indicate a complication.
Pain assessment requires clinical judgment, especially to rule out retroperitoneal hemorrhage.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence for managing a hazardous drug spill is: 1) Secure the perimeter to protect others, 2) Retrieve the specialized spill kit, 3) Don appropriate PPE, 4) Contain the spill with absorbent materials, 5) Decontaminate the floor surface, and 6) Dispose of all cleanup materials and PPE in a bulk hazardous waste bin.
The correct sequence prioritizes immediate bystander safety, followed by preparation (getting the kit), self-protection (donning PPE), execution of cleanup (containment and decontamination), and finally, safe disposal according to OSHA and ONS guidelines.

Step-by-Step Solution

1
Secure the immediate area
Prevents inadvertent exposure to others
Safety of bystanders and clients is the absolute first priority in any hazardous material incident. Leaving an unmonitored spill to get supplies can lead to tracking of the chemical.
2
Obtain the spill kit
Provides the necessary tools for safe cleanup
Specialized equipment, such as specific absorbents and chemical-rated PPE, is required to safely handle antineoplastic agents.
3
Don PPE
Protects the nurse from toxic exposure
The nurse must be fully protected (double gloves, gown, face/respiratory protection) before approaching the concentrated hazardous material.
4
Contain the liquid spill
Stops the physical spread of the medication
Absorbent pads prevent the drug from contaminating a larger surface area and make the bulk cleanup safer.
5
Decontaminate the surface
Removes hazardous chemical residue
Detergent and water (or kit-provided neutralizing agents) lift any remaining microscopic drug particles from the floor.
6
Dispose of waste safely
Completes the hazardous spill protocol
All items that touched the drug are now considered hazardous waste and require specialized disposal to protect environmental services workers.

Key Concept

Management of hazardous antineoplastic medication spills requires a strict sequence of securing the area, protecting the healthcare worker with specific PPE, containing the chemical, decontaminating the environment, and properly disposing of hazardous waste.
Question 2691Question →

A nurse is caring for a 68-year-old client with symptomatic anemia (hemoglobin 6.8 g/dL) who is prescribed a packed red blood cell (PRBC) transfusion. To reduce the risk of adverse reactions and ensure safe administration, place the following steps in the correct chronological order.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct chronological sequence is to first verify the prescription and consent, then assess IV patency and baseline vital signs, retrieve the blood from the blood bank, perform the two-nurse bedside verification, and finally initiate the transfusion while monitoring the client closely for the first 15 minutes.
Safe administration of blood products requires a strict chronological sequence to minimize the risk of complications such as transfusion reactions or product waste. The nurse must first ensure a valid prescription and consent exist. Second, assessing IV patency and vital signs ensures the client is physiologically ready to receive the blood, preventing product waste if the IV needs restarting. Third, the blood is retrieved from the blood bank, as it must be initiated within 30 minutes. Fourth, two-nurse bedside verification prevents fatal ABO incompatibility errors. Finally, the transfusion is started slowly, with the nurse remaining present for the first 15 minutes to monitor for any acute life-threatening reactions.

Step-by-Step Solution

1
Verify prescription and consent.
Ensures legal authorization to proceed.
Blood administration requires explicit provider orders and informed client consent due to the inherent physiological risks.
2
Assess IV patency and baseline vital signs.
Confirms physical readiness for the transfusion.
Prevents blood product waste if IV access is compromised or if baseline vital signs indicate a contraindication to starting the transfusion (e.g., a high fever).
3
Retrieve blood from the blood bank.
Obtains the necessary blood product.
Blood must be initiated within 30 minutes of leaving the temperature-controlled blood bank environment to prevent bacterial growth and RBC degradation.
4
Perform two-nurse bedside verification.
Confirms the correct product is given to the correct client.
Independent double-checking at the bedside is the primary method to prevent ABO incompatibility and acute hemolytic transfusion reactions.
5
Initiate slowly and monitor for 15 minutes.
Detects early signs of adverse physiological reactions.
Severe transfusion reactions (such as anaphylactic or hemolytic reactions) typically present within the first 15 minutes or first 50 mL of the infusion.

Question 2692Question →

A nursing care coordinator at a primary care clinic is auditing client charts to ensure adherence to national health maintenance guidelines. Which of the following planned actions indicates that the coordinator correctly applies evidence-based screening principles?

Show answer & explanation

Answer: Recommending an annual low-dose computed tomography (LDCT) scan to screen for lung cancer in a 62-year-old client with a 30-pack-year smoking history.

Answer

The correct action is recommending an annual low-dose computed tomography (LDCT) scan to screen for lung cancer in a 62-year-old client with a 30-pack-year smoking history.
The correct answer demonstrates accurate knowledge of current national health screening guidelines. The United States Preventive Services Task Force (USPSTF) recommends annual screening for lung cancer with low-dose computed tomography (LDCT) in adults aged 50 to 80 years who have a 20 pack-year smoking history. The client in this scenario meets all criteria for this secondary prevention measure.

Step-by-Step Solution

1
Evaluate the lung cancer screening recommendation.
Identified as correct.
Current evidence-based guidelines recommend annual LDCT screening for adults aged 50 to 80 years who have a 20 pack-year or greater smoking history and currently smoke or have quit within the past 15 years.
2
Analyze the classification of vaccines as secondary prevention.
Identified as incorrect.
Immunizations are primary prevention strategies designed to prevent the onset of disease, whereas secondary prevention involves screenings for early disease detection.
3
Assess the approach to sudden confusion in an older adult.
Identified as incorrect.
Sudden cognitive decline (delirium) is always pathological and requires urgent screening to identify reversible causes like infection; it is never a normal age-related change.
4
Review the delegation of reading a tuberculin skin test (TST).
Identified as incorrect.
Interpreting the induration of a TST requires clinical judgment and assessment, which cannot be delegated to an unlicensed assistive personnel (UAP).

Question 2693Question →

A nurse is observing staff members handle various hazardous and infectious materials on a medical-surgical unit. Which observed actions indicate appropriate infection control and safety practices? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Placing a surgical dressing heavily saturated with blood into a red biohazard bag.; Disposing of a used, uncapped intravenous catheter needle directly into a rigid, puncture-resistant sharps container.; Discarding an empty intravenous bag used for a hazardous antineoplastic medication into a designated trace chemotherapy waste container.

Answer

The correct actions are placing a heavily blood-soaked dressing in a red biohazard bag, disposing of an uncapped needle in a sharps container, and discarding an empty antineoplastic IV bag in a trace chemotherapy waste container.
The correct actions demonstrate strict adherence to OSHA and CDC guidelines for hazardous and infectious waste segregation. Items saturated with blood that can release fluids when compressed meet the criteria for regulated medical waste and require a red biohazard bag. Used needles must be immediately placed uncapped into a rigid, puncture-resistant sharps container to prevent needlestick injuries. Finally, trace antineoplastic waste, such as empty IV bags and tubing, must be placed in a designated trace chemotherapy container (typically yellow) rather than regular trash or red bags.

Step-by-Step Solution

1
Evaluate the disposal of the blood-soaked surgical dressing.
It is correctly placed in a red biohazard bag.
OSHA defines items saturated with blood or infectious materials as regulated medical waste, requiring segregation into red biohazard bags.
2
Evaluate the disposal of the incontinent pad containing non-bloody urine.
It is incorrectly placed in a red biohazard bag.
Routine bodily fluids without visible blood are not regulated medical waste and should be placed in standard trash receptacles.
3
Evaluate the disposal of the used, uncapped needle.
It is correctly placed in a rigid sharps container.
Standard precautions dictate that sharps must be disposed of immediately without recapping to prevent needlestick injuries.
4
Evaluate the practice of routinely double-bagging isolation room trash.
It is an incorrect practice.
CDC guidelines state that a single, sturdy bag is sufficient for isolation waste unless the exterior becomes contaminated or punctured.
5
Evaluate the disposal of the empty antineoplastic intravenous bag.
It is correctly placed in a trace chemotherapy waste container.
Hazardous drugs require specialized incineration, so trace waste must be segregated into designated containers (usually yellow), not standard red biohazard bags.

Key Concept

Correct segregation and disposal of hazardous and infectious medical waste according to OSHA and CDC guidelines.
Question 2694Question →

A nurse in the intensive care unit is caring for a client who weighs 187 lbs187\text{ lbs} and is receiving a continuous intravenous infusion of norepinephrine for septic shock. The medication is supplied as 4 mg4\text{ mg} of norepinephrine in 250 mL250\text{ mL} of 5%5\% dextrose in water (D5WD_5W). The infusion is currently running at 17 mL/hr17\text{ mL/hr}.

The client's current vital signs include a heart rate of 112 bpm112\text{ bpm} and a blood pressure of 82/46 mmHg82/46\text{ mmHg} (mean arterial pressure [MAP] 58 mmHg58\text{ mmHg}).

The provider's prescribed titration parameters state: "Titrate norepinephrine infusion by 0.02 mcg/kg/min0.02\text{ mcg/kg/min} every 5 minutes to maintain a MAP ≥65 mmHg\geq 65\text{ mmHg}."

Based on the client's current MAP, the nurse performs one titration increase. What should the nurse set the new infusion pump rate to in mL/hr\text{mL/hr}? (Record answer to the nearest tenth.)

Show answer & explanation

Answer: 23.4

Answer

The new infusion pump rate should be set to 23.4 mL/hr.
The client's mean arterial pressure (MAP) is 58 mmHg58\text{ mmHg} ([82+2(46)]÷3[82 + 2(46)] \div 3), indicating the need to titrate the norepinephrine upward per the provider's parameters (MAP less than 65 mmHg65\text{ mmHg}). First, the weight is converted to 85 kg85\text{ kg} (187÷2.2187 \div 2.2). The ordered increase is 0.02 mcg/kg/min0.02\text{ mcg/kg/min}, which equals an additional 1.7 mcg/min1.7\text{ mcg/min} (0.02×850.02 \times 85) or 102 mcg/hr102\text{ mcg/hr} (1.7×601.7 \times 60). The concentration of the IV bag is 16 mcg/mL16\text{ mcg/mL} (4,000 mcg÷250 mL4,000\text{ mcg} \div 250\text{ mL}). The required increase in fluid volume is 6.375 mL/hr6.375\text{ mL/hr} (102÷16102 \div 16). Adding this to the baseline rate of 17 mL/hr17\text{ mL/hr} yields 23.375 mL/hr23.375\text{ mL/hr}. Rounding to the nearest tenth provides the final correct rate of 23.4 mL/hr23.4\text{ mL/hr}.

Step-by-Step Solution

1
Assess the clinical situation to determine the necessary intervention.
The client's MAP is 58 mmHg58\text{ mmHg}, which is below the target of ≥65 mmHg\geq 65\text{ mmHg}. Therefore, a titration increase of 0.02 mcg/kg/min0.02\text{ mcg/kg/min} is required.
Vasopressor infusions must be titrated according to prescribed parameters based on objective hemodynamic data.
2
Convert the client's weight from pounds to kilograms.
187 lbs÷2.2 lbs/kg=85 kg187\text{ lbs} \div 2.2\text{ lbs/kg} = 85\text{ kg}.

A nurse provides care for a client hospitalized with a severe respiratory infection. During the shift, the client repeatedly activates the call bell for minor demands, attempts to touch the nurse's arm, and makes sexually explicit remarks regarding the nurse's appearance. Which of the following is the priority behavioral intervention for the nurse to implement?

Show answer & explanation

Answer: Directly inform the client that the comments are unacceptable and clearly define the professional boundaries of the nurse-client relationship.

Answer

The priority intervention is to directly inform the client that their comments are unacceptable and clearly establish professional boundaries.
The nurse must immediately set firm, clear limits on inappropriate behavior to establish professional boundaries and maintain a therapeutic environment. Direct communication without anger or judgment is the most effective initial behavioral intervention when a client exhibits boundary-testing or sexually explicit behavior.

Step-by-Step Solution

1
Assess the client's behavior and the immediate risk to staff.
The client is demonstrating inappropriate, boundary-testing behavior without physical violence.
Accurate assessment determines the appropriate level of intervention required.
2
Determine the least restrictive intervention to manage the behavior.
Verbal limit-setting is identified as the first-line, least restrictive approach.
Nursing care must always escalate from the least restrictive to the most restrictive interventions.
3
Implement the behavioral intervention.
The nurse provides clear, direct feedback about unacceptable behavior and reinforces professional boundaries.
Clear boundaries stop the behavior, maintain a safe environment, and establish expectations for future interactions.

A nurse is preparing to transfer a client who is 2 days postoperative following a right total hip arthroplasty (posterior approach) from the bed to a bedside chair. In what order should the nurse perform the following actions? (Arrange the steps in the correct sequential order)

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: Place the chair on the left side, help the client sit on the bed edge with the right leg extended, apply the transfer belt, stand bearing weight on the left leg while extending the right leg, and pivot on the left foot to sit in the chair.
The sequence follows the standard principles of safe patient handling combined with strict posterior total hip arthroplasty precautions. First, the environment is prepared by placing the chair on the client's unaffected (left) side. Second, the client is assisted to sit on the edge of the bed while the operative (right) leg is kept extended to prevent hip flexion greater than 90 degrees. Third, a transfer belt is applied for safety. Fourth, the client stands, bearing weight on the strong left leg while continuing to keep the right leg extended. Finally, the client pivots on the strong left leg, reaches back for the chair, and sits down while maintaining the operative leg in extension to prevent dislocation.

Step-by-Step Solution

1
Place the bedside chair at a 45-degree angle on the client's left side and lock the wheels.
The environment is prepared for a safe transfer toward the strong side.
Transfers should always move toward the client's unaffected (strong) side. Environmental safety must be secured before moving the client.
2
Help the client to a sitting position on the edge of the bed while maintaining the right leg in an extended position.
The client is positioned at the edge of the bed without violating hip precautions.
Keeping the operative (right) leg extended prevents the hip from flexing beyond 90 degrees, which could cause dislocation in a posterior approach arthroplasty.
3
Secure a transfer belt snugly around the client's waist over their clothing.
The nurse has a safe, ergonomic method to assist the client during the weight-bearing phase.
The transfer belt is applied once the client is sitting to ensure a snug fit and safe grasping point before the client attempts to stand.
4
Instruct the client to bear weight primarily on the left leg and stand while keeping the right leg extended.
The client achieves a standing position safely.
Bearing weight on the unaffected (left) leg protects the surgical site. Extending the right leg forward prevents excessive hip flexion during the transition from sitting to standing.
5
Assist the client to pivot on the left foot and reach back for the chair armrests.
The client safely completes the transfer and sits in the chair.
Pivoting on the strong leg avoids twisting the operative hip. Reaching back for the armrests allows for a controlled descent, maintaining the right leg in extension to avoid breaking the 90-degree flexion rule.

A nurse is caring for a client with community-acquired pneumonia who has a continuous primary intravenous (IV) infusion of 0.9% sodium chloride running at 75 mL/hr. The healthcare provider prescribes an intermittent dose of IV ceftriaxone to infuse over 30 minutes. Arrange the following steps in the correct order for safely setting up and initiating the secondary infusion using a gravity drip system.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence begins with verifying fluid compatibility, followed by priming the secondary tubing, scrubbing the primary line access port, connecting the tubing and lowering the primary bag, and finally regulating the drip rate.
Safe administration of a secondary IV piggyback medication via a gravity system requires a logical sequence that prevents patient harm. Verification of fluid compatibility is the absolute first step. Next, the secondary tubing is primed with the medication to prevent air embolism. Infection control follows, requiring the nurse to vigorously scrub the upper needleless access port before any connection is made. Connecting the tubing and utilizing an extension hook to lower the primary bag utilizes gravity to prioritize the secondary infusion over the primary fluid. Finally, regulating the drip rate ensures accurate and safe dosing over the prescribed time frame.

Step-by-Step Solution

1
Verify the compatibility of the IV ceftriaxone with the continuous primary infusion of 0.9% sodium chloride.
The nurse confirms that the two fluids will not precipitate or interact adversely.
Safety must be established first; incompatible fluids can cause crystallization in the IV line, leading to a blocked catheter or embolus.
2
Spike the ceftriaxone bag and prime the secondary intravenous tubing.
The secondary IV line is filled with medication and is completely free of air bubbles.
Air must be purged from the secondary tubing before attaching it to the primary system to prevent a life-threatening air embolism.
3
Scrub the needleless access port on the primary tubing located above the roller clamp.
The access port is properly disinfected.
Vigorous scrubbing with an antimicrobial swab maintains infection control and prevents the introduction of microorganisms into the patient's circulatory system.
4
Connect the secondary tubing to the primary line and hang the primary fluid bag lower than the ceftriaxone bag.
The secondary line is successfully integrated, and a proper gravity gradient is established.
In a gravity drip system, the secondary bag must be hung physically higher than the primary bag so hydrostatic pressure allows the secondary medication to infuse first.
5
Open the secondary roller clamp and adjust the flow rate to the prescribed drops per minute.
The secondary medication begins infusing at the correct therapeutic speed.
Proper flow rate regulation ensures the patient receives the antibiotic safely over the prescribed 30 minutes without causing speed shock or fluid overload.

Key Concept

The correct procedural sequence for administering a secondary IV piggyback (IVPB) infusion prioritizes chemical compatibility, stringent infection control, and the physical principles of hydrostatic pressure in a gravity system.

A client on a busy cardiovascular step-down unit becomes increasingly agitated. The client's room is brightly lit, and multiple monitor alarms are continuously sounding. The client points frantically at the electrocardiogram (ECG) lead wires on their chest and shouts, 'Get these worms off of me!' Which of the following nursing interventions should the nurse implement to manage this perceptual alteration? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Group routine nursing care tasks together to provide uninterrupted periods of rest.; Inform the client, 'I see the wires for your heart monitor, but I do not see any worms.'; Decrease environmental stimuli by dimming the overhead lights and lowering monitor alarm volumes to safe limits.

Answer

The correct interventions are grouping nursing care tasks, presenting reality regarding the ECG wires, and decreasing environmental stimuli like lights and alarms.
The client is experiencing an illusion driven by sensory overload. The most appropriate interventions involve directly reducing the sensory burden (dimming lights, lowering alarms), clustering care to allow for uninterrupted sleep, and using therapeutic communication to gently present reality without arguing or validating the altered perception.

Step-by-Step Solution

1
Analyze the client's symptoms and environmental context.
The client is in a high-stimulus environment (alarms, bright lights) and is misinterpreting a real physical object (ECG wires) as worms.
Identifying the phenomenon as an illusion exacerbated by sensory overload guides the selection of appropriate interventions.
2
Evaluate communication strategies for perceptual alterations.
The nurse must present reality without arguing or reinforcing the false perception.
Therapeutic communication maintains trust and helps orient the client to reality.
3
Determine appropriate environmental and delegatory actions.
The environment must be modified to reduce sensory input, and nursing assessments must remain with the registered nurse.
Sensory overload requires decreased stimulation and clustered care. Neurological evaluation of an unstable client is outside the scope of practice for a UAP.

A nurse is preparing to administer an intermittent intravenous (IV) secondary medication (piggyback) to a client who has a continuous primary IV infusion of 0.9%0.9\% sodium chloride. Which of the following actions should the nurse take to ensure safe administration? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Verify the compatibility of the secondary medication with the primary 0.9%0.9\% sodium chloride infusion using a drug reference guide.; Assess the intravenous insertion site for signs of infiltration, redness, or swelling before initiating the secondary infusion.; Position the secondary medication bag higher than the primary intravenous fluid bag on the IV pole.

Answer

The correct actions include verifying medication compatibility, assessing the intravenous insertion site prior to administration, and positioning the secondary medication bag higher than the primary fluid bag.
Safe administration of a secondary IV medication requires verifying compatibility to prevent adverse chemical reactions, assessing the IV site to confirm patency and prevent tissue damage, and hanging the secondary bag higher than the primary bag so that gravity allows it to infuse first.

Step-by-Step Solution

1
Evaluate the need for compatibility verification.
Identified as a necessary safety action.
Mixing incompatible medications can cause crystallization or chemical changes in the IV tubing, which poses a severe risk to the client.
2
Evaluate the necessity of IV site assessment.
Identified as a necessary pre-administration action.
Ensuring IV patency prevents complications like infiltration, phlebitis, and tissue necrosis.
3
Evaluate the correct physical setup for a secondary (piggyback) infusion.
Identified that the secondary bag must be hung higher than the primary bag.
Gravity dictates that the fluid in the highest bag will infuse first, which is the intended mechanism for a piggyback setup.
4
Evaluate the safety of estimating infusion rates.
Identified as an unsafe practice.
Precise dosage calculations and rate control are required to ensure patient safety and prevent speed shock.
5
Evaluate the procedure for handling incompatible fluids.
Identified as an unsafe practice to simply pause the primary infusion without flushing.
The line must be flushed with a compatible solution, or a new line must be established, to completely prevent the mixing of incompatible substances.

A nurse is developing a plan of care to maintain skin integrity and provide comfort for an older adult client who is immobile. Which of the following interventions is the most appropriate for the nurse to include?

Show answer & explanation

Answer: Use a draw sheet or friction-reducing device to lift the client when changing their position in bed.

Answer

The most appropriate intervention is to use a draw sheet or friction-reducing device to lift the client when changing their position in bed.
Using a draw sheet or a friction-reducing device allows the nurse to lift rather than drag the client across the bed linens. This intervention directly prevents friction and shearing forces, which are primary contributors to skin breakdown and pressure injuries in immobile older adults.

Step-by-Step Solution

1
Identify the client's primary needs based on the clinical scenario.
The client is an immobile older adult, which places them at high risk for friction, shear, and pressure injuries.
Understanding the physiological risks associated with immobility guides the selection of protective care measures.
2
Evaluate the safety and physiological impact of each proposed intervention.
Lifting with a draw sheet prevents shear. Conversely, prolonged 90-degree head elevation increases shear. Delegating an initial assessment violates scope of practice. Dismissing sudden incontinence ignores potential pathology.
Basic care interventions must align with evidence-based standards for safe positioning, proper delegation, and accurate clinical judgment.
3
Select the nursing action that safely promotes comfort and skin integrity.
Using a draw sheet or friction-reducing device is identified as the correct action.
It actively protects the client's skin from mechanical damage during necessary repositioning.

Key Concept

Prevention of skin breakdown and shearing forces during bed mobility.
