Question 241Question →

A medical-surgical nurse is providing discharge education to a 58-year-old client recently diagnosed with stage II chronic kidney disease and essential hypertension. The client asks the nurse for strategies to manage the new diagnoses and prevent further renal damage. To correctly implement a tertiary disease prevention strategy, what specific instruction must the nurse provide?

Show answer & explanation

Answer: Record your blood pressure at home daily and strictly adhere to your prescribed antihypertensive medication schedule.

Answer

The instruction to record blood pressure daily and adhere to antihypertensive medications.
Tertiary prevention focuses on minimizing the progression and complications of an already established disease. For a client with diagnosed chronic kidney disease and hypertension, strict blood pressure control through consistent monitoring and medication adherence is a core tertiary intervention that directly prevents further target-organ damage.

Step-by-Step Solution

1
Analyze the client's clinical profile and the nurse's goal.
The client has existing, diagnosed conditions (stage II chronic kidney disease and hypertension). The goal is to apply a 'tertiary' disease prevention strategy.
Identifying the baseline health status dictates which level of prevention is clinically appropriate.
2
Define tertiary disease prevention in the context of nursing practice.
Tertiary prevention focuses on minimizing the progression, complications, and disability associated with an already established disease.
Differentiating primary (preventing disease), secondary (early detection/screening), and tertiary (managing existing disease) prevention is required to select the correct intervention.
3
Evaluate the options against the definition of tertiary prevention and sound clinical judgment.
Managing blood pressure directly slows the progression of existing kidney disease, fitting the definition of tertiary prevention. The other options describe secondary screening, dangerous dismissal of pathological symptoms, or inappropriate triage.
Matching the correct definition to the clinical action ensures safe and effective client education.

Question 242Question →

During a clinic visit, a client reports continuous, severe vomiting over the last two days due to a gastrointestinal illness. The nurse anticipates that this prolonged loss of gastric secretions places the client at highest risk for which acid-base imbalance?

Show answer & explanation

Answer: Metabolic alkalosis

Answer

Metabolic alkalosis
The correct answer is metabolic alkalosis because prolonged vomiting depletes the body of gastric acid (hydrochloric acid). The significant loss of hydrogen ions causes a compensatory increase in systemic blood pH and bicarbonate levels, leading to a metabolic alkaline state. This is a fundamental physiological adaptation to upper gastrointestinal fluid loss.

Step-by-Step Solution

1
Identify the primary source and mechanism of fluid loss.
The client is experiencing severe, continuous vomiting.
Determining the route of fluid loss is the first step in predicting the associated physiological disruption.
2
Analyze the chemical composition of the lost fluid.
Stomach secretions are highly acidic because they contain large amounts of hydrochloric acid.
Understanding what electrolytes and ions are being depleted helps identify the specific acid-base shift.
3
Determine the resulting systemic imbalance.
The massive loss of hydrogen ions (acid) from the stomach leaves the blood with a relative excess of base (bicarbonate).
A decrease in systemic hydrogen ions directly increases blood pH, defining the state as metabolic alkalosis.

Question 243Question →

A 3535-year-old client is 66 hours post-operative following an open reduction and internal fixation (ORIF) of a severe pelvic fracture. The client is receiving a continuous epidural infusion of bupivacaine and fentanyl. The nurse collects the following assessment data:

AssessmentFinding
Heart rate114114 beats/minute
Blood pressure106/82 mm Hg106/82 \text{ mm Hg}
Respiratory rate2222 breaths/minute
Arterial Blood GaspH 7.317.31, PaCO2\text{PaCO}_2 34 mm Hg34 \text{ mm Hg}, HCO3−\text{HCO}_3^- 16 mEq/L16 \text{ mEq/L}
Urine output35 mL35 \text{ mL} over the past 22 hours
SensoriumMildly restless and reports intense thirst

Which of the following actions should the nurse perform immediately to reduce the risk of further physiological deterioration?

Show answer & explanation

Answer: Position the client flat and prepare to initiate rapid intravenous fluid resuscitation with isotonic crystalloids

Answer

Position the client flat and prepare to initiate rapid intravenous fluid resuscitation with isotonic crystalloids.
The client's assessment data strongly indicate compensatory hypovolemic (hemorrhagic) shock, a major risk following pelvic trauma. In this early stage, the systolic blood pressure may appear deceptively normal due to intense peripheral vasoconstriction, but the narrow pulse pressure (24 mm Hg24 \text{ mm Hg}) and lactic acidosis (metabolic acidosis) reveal severe tissue hypoperfusion. Positioning the client flat maximizes venous return to the heart, and rapid isotonic crystalloid administration is the immediate priority to restore intravascular volume.

Step-by-Step Solution

1
Analyze the client's vital signs and hemodynamic parameters.
The pulse pressure is extremely narrow (106−82=24 mm Hg106 - 82 = 24 \text{ mm Hg}), accompanied by tachycardia (114 bpm114 \text{ bpm}) and severe oliguria (17.5 mL/hr17.5 \text{ mL/hr}).
A narrow pulse pressure combined with tachycardia is a cardinal sign of compensatory hypovolemic shock, even when the systolic pressure appears relatively stable above 100 mm Hg100 \text{ mm Hg}.
2
Evaluate the arterial blood gas (ABG) results and clinical presentation.
The ABG reveals an uncompensated metabolic acidosis (pH 7.317.31, low HCO3−\text{HCO}_3^- 16 mEq/L16 \text{ mEq/L}). The client is restless and thirsty.
In the context of severe pelvic trauma, this metabolic acidosis reflects lactic acid accumulation due to severe tissue hypoperfusion. Restlessness and thirst are classic indicators of cellular hypoxia and volume depletion.
3
Determine the priority nursing intervention to reduce physiological risk.
The highest priority is to optimize venous return by positioning the client flat (supine) and preparing for rapid intravascular volume expansion.
Immediate fluid resuscitation reverses the hypovolemic state and prevents progression to irreversible shock and multi-organ failure.

Key Concept

Recognizing early compensatory hypovolemic shock via narrow pulse pressure and metabolic acidosis, and intervening promptly with volume resuscitation.
Question 244Question →

A pediatric clinic nurse is developing a self-care management plan for a 6-year-old client recently diagnosed with moderate persistent asthma. The nurse is discussing daily routines and responsibilities with the child and their parents. Which instruction best promotes appropriate self-care competency for this client?

Show answer & explanation

Answer: Teaching the child to identify the color zones on their peak flow meter and to immediately notify an adult if the marker drops below the green zone.

Answer

The correct answer is teaching the child to identify the color zones on their peak flow meter and to immediately notify an adult if the marker drops below the green zone.
The correct answer appropriately involves the 6-year-old child in their own care by utilizing simple, concrete visual cues (color-coded peak flow zones). This aligns perfectly with the cognitive abilities of early school-aged children, fostering a sense of industry and autonomy while ensuring safety by establishing a clear rule to seek adult intervention when the reading is abnormal.

Step-by-Step Solution

1
Analyze the client's developmental stage.
The client is 6 years old (early school-age, Erikson's Industry vs. Inferiority, Piaget's Preoperational/Concrete Operational transition).
Developmental stage determines what self-care tasks are safe and cognitively appropriate.
2
Evaluate the proposed self-care tasks against the developmental stage.
Using color-coded zones (green, yellow, red) is concrete and understandable for a 6-year-old. Calculating medication doses is too abstract and unsafe.
Self-care education must match the client's cognitive abilities to be effective and safe.
3
Review the remaining options for general clinical principles.
Delegating assessment to an aide violates delegation rules. Calling monitoring a 'cure' or 'primary prevention' is factually incorrect regarding disease processes.
Options must adhere to legal scope of practice and accurate pathophysiological concepts.

Question 245Question →

A registered nurse is caring for an older adult client with cognitive impairment who is receiving continuous enteral feeding via a percutaneous endoscopic gastrostomy (PEG) tube. The client is increasingly restless, frequently scratching at the peri-stomal skin, and attempting to pull the feeding tubing. Which of the following actions is the most appropriate for the nurse to implement?

Show answer & explanation

Answer: Route the enteral tubing underneath the client's clothing and provide a tactile activity apron.

Answer

The most appropriate action is to route the enteral tubing underneath the client's clothing and provide a tactile activity apron.
Routing the tubing under clothing and providing a tactile apron represents the least restrictive approach to protecting the medical device. It successfully distracts the cognitively impaired client and camouflages the tube, adhering to basic care and comfort principles without resorting to restraints or compromising physiological safety.

Step-by-Step Solution

1
Analyze the client's presentation and current risk factors.
The client is cognitively impaired, receiving continuous enteral feeding, and at risk for device dislodgement due to restlessness.
Identifying the primary safety and comfort risks dictates the priority of nursing interventions.
2
Evaluate the proposed interventions against safety standards and the nursing scope of practice.
Lowering the head of the bed causes aspiration risk; delegating skin evaluation to a UAP violates delegation principles; and applying restraints skips required alternative measures.
Nursing actions must adhere to safety guidelines (e.g., aspiration precautions), legal standards (e.g., proper delegation), and institutional protocols (e.g., restraint use).
3
Select the intervention that ensures client safety using the least restrictive method.
Camouflaging the tube and providing sensory distraction is selected.
These are effective, first-line restraint alternatives that maintain the integrity of the feeding tube while promoting client comfort.

An adult client experiencing recurrent seizure activity is admitted to the neurological unit. The client has a single patent 2020-gauge peripheral intravenous catheter infusing 5%5\% dextrose in 0.45%0.45\% sodium chloride at 80 mL/hr80 \text{ mL/hr}. The provider prescribes a stat loading dose of phenytoin 1000 mg1000 \text{ mg} intravenously. The pharmacy delivers the medication diluted in 100 mL100 \text{ mL} of normal saline. What is the safest method for the nurse to administer this medication?

Show answer & explanation

Answer: Pause the primary infusion, flush the catheter with normal saline, infuse the phenytoin over 3030 minutes, and flush again with normal saline.

Answer

The safest method is to pause the primary dextrose infusion, flush the catheter with normal saline, infuse the phenytoin over 30 minutes, and flush again with normal saline.
The correct action is to pause the primary dextrose infusion and flush the line with normal saline before and after administering the phenytoin. Phenytoin is highly incompatible with dextrose-containing solutions and will precipitate if mixed, forming solid crystals in the tubing. Because the medication is prescribed as a stat dose for recurrent seizures, utilizing the existing patent catheter by clearing it with normal saline is the fastest and safest approach. Additionally, administering the dose over 30 minutes ensures the infusion rate remains below the maximum safe limit of 50 mg/min50 \text{ mg/min}.

Step-by-Step Solution

1
Identify the primary fluid composition and check drug compatibility.
The primary fluid contains dextrose, which is highly incompatible with phenytoin.
Mixing phenytoin with dextrose solutions causes immediate crystallization and precipitation in the intravenous tubing.
2
Calculate the safe infusion rate for the prescribed dose.
The maximum safe rate for intravenous phenytoin is 50 mg/min50 \text{ mg/min}. For a 1000 mg1000 \text{ mg} dose, the absolute minimum infusion time is 2020 minutes (1000÷501000 \div 50).
Infusing phenytoin faster than 50 mg/min50 \text{ mg/min} can cause severe cardiovascular toxicity, including hypotension and arrhythmias.
3
Determine the most efficient and safe administration route utilizing existing resources.
The existing line must be cleared of dextrose using normal saline (flush-administer-flush technique).
This prevents precipitation without unnecessarily delaying a 'stat' medication to insert a new catheter.

Question 247Question →

A nurse is educating a client who has a right fractured tibia and is prescribed non-weight-bearing status. The client is learning to ascend a flight of stairs using axillary crutches. In what order should the nurse instruct the client to perform the following movements?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The client should first assume a tripod position, transfer weight to the crutches, advance the unaffected leg up the step, shift weight to the unaffected leg, and finally bring the affected leg and crutches up to the step.
When ascending stairs with crutches, the fundamental principle is 'up with the good, down with the bad.' The client must begin with a stable tripod stance, support their weight on the crutches, and step up with the unaffected (strong) leg first. Once the strong leg is on the step, the client shifts their weight onto it and uses its strength to lift the affected leg and the crutches simultaneously up to the step.

Step-by-Step Solution

1
Assume the tripod position facing the bottom of the stairs.
The client establishes a stable base.
A secure starting stance is necessary for balance and safety before moving.
2
Transfer body weight entirely onto the crutches.
The client's legs are freed from bearing weight.
This allows the client to lift the strong leg without losing balance.
3
Move the unaffected left leg up onto the stair tread.
The strong leg is positioned on the higher level.
When ascending stairs, the unaffected ('good') leg always goes first to provide the power to lift the body weight.
4
Shift body weight from the crutches onto the unaffected left leg.
Weight is transferred to the elevated strong leg.
The strong leg must bear the body weight to pull the rest of the body upward.
5
Advance the right leg and both crutches together up to the step.
The client completes the ascent of one step.
The crutches and the affected leg follow the strong leg to the new level, completing the movement sequence.

Question 248Question →

The interdisciplinary team is managing a client's induced labor. Analysis of the continuous electronic fetal tracing reveals a baseline heart rate of 155 bpm with minimal variability. The nurse notes a pattern of gradual, symmetrical decreases in the fetal heart rate where the onset, nadir, and recovery of each deceleration occur after the beginning, peak, and end of the respective uterine contractions. Given these findings, which of the following immediate actions must the nurse implement? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Terminate the oxytocin infusion immediately.; Reposition the client into a lateral decubitus position.; Administer an intravenous bolus of lactated Ringer's solution.

Answer

The nurse must terminate the oxytocin infusion immediately, reposition the client into a lateral decubitus position, and administer an intravenous bolus of lactated Ringer's solution.
The clinical presentation describes late decelerations, which signify uteroplacental insufficiency and fetal hypoxemia. Appropriate intrauterine resuscitation includes maximizing placental blood flow and maternal oxygenation. Terminating the oxytocin stops uterine contractions that are compressing placental vessels. Repositioning the client laterally relieves compression of the inferior vena cava, increasing cardiac output. Administering an intravenous fluid bolus expands intravascular volume, further improving perfusion to the placenta.

Step-by-Step Solution

1
Analyze the fetal heart rate tracing to identify the specific pattern.
The pattern shows a gradual decrease with the nadir occurring after the contraction peak, which defines a late deceleration.
Accurate pattern recognition is necessary to determine the underlying pathophysiology and appropriate interventions.
2
Correlate the identified pattern with its physiological cause.
Late decelerations are caused by uteroplacental insufficiency, indicating the fetus is experiencing hypoxemia during contractions. The minimal variability further suggests potential acidemia.
Understanding that the placenta is not delivering adequate oxygen guides the nurse toward resuscitation measures.
3
Prioritize interventions that maximize maternal oxygenation and placental blood flow.
The nurse determines that immediate intrauterine resuscitation is required, prioritizing actions over further assessments.
Delaying treatment or misinterpreting the severity can lead to severe fetal compromise or hypoxic-ischemic injury.
4
Select the appropriate intrauterine resuscitation actions.
The correct actions are stopping oxytocin (to stop contractions), repositioning laterally (to relieve caval compression), and giving an IV fluid bolus (to expand volume).
These targeted actions directly reverse the mechanical and physiological factors contributing to uteroplacental insufficiency.

A community health nurse is developing a comprehensive self-care and health maintenance plan for an 84-year-old client with mild cognitive decline who lives with family. Which actions by the nurse are appropriate? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Organize the client's daily grooming supplies in a consistent, visible location.; Allow the client extra time to complete bathing tasks independently.; Implement the use of a large-print, color-coded pill organizer for daily medications.

Answer

The nurse should organize grooming supplies in a consistent location, allow extra time for independent bathing, and implement a large-print, color-coded pill organizer.
The correct interventions focus on maximizing the client's remaining capabilities and adapting the environment to support independence. Organizing grooming supplies in a consistent location and using a color-coded pill organizer compensate for mild cognitive decline by simplifying tasks. Furthermore, allowing the client extra time to complete bathing independently prevents premature dependence and preserves their functional status.

Step-by-Step Solution

1
Analyze the client's profile and the goal of care.
The client is 84 years old with mild cognitive decline, and the goal is to promote self-care and health maintenance.
Understanding the client's baseline and goals directs appropriate nursing interventions.
2
Evaluate each proposed intervention for safety, appropriateness, and promotion of independence.
Environmental consistency, adaptive devices, and allowing extra time directly support self-care. Conversely, sudden confusion requires medical evaluation, initial assessments cannot be delegated, and vaccines are still necessary.
Nursing actions must align with evidence-based practice, proper delegation rules, and gerontological standards.

Key Concept

Promoting self-care and independence in older adults requires adaptive strategies while maintaining safety, accurate assessment of acute changes, and proper delegation.
Question 250Question →

A nurse practitioner is completing a comprehensive health evaluation for a 79-year-old client in an outpatient clinic. The client mentions various physical adaptations they have noticed over the past year. Which client statement requires further investigation because it represents an abnormal disease process rather than a typical physiological change of aging?

Show answer & explanation

Answer: I frequently experience urinary leakage before I can make it to the restroom.

Answer

The statement about experiencing frequent urinary leakage before reaching the restroom indicates a pathological process.
The correct answer identifies urinary leakage as pathological. A common clinical misconception is that incontinence is a normal part of getting older. While structural changes such as decreased bladder capacity and weakened detrusor muscle contractility occur, involuntary loss of urine is considered abnormal and signifies a treatable underlying condition that requires medical intervention.

Step-by-Step Solution

1
Analyze the stem to determine what is being asked.
The question requires identifying a pathological condition (abnormal disease process) masked as an age-related change.
Nurses must be able to differentiate between normal senescence and acute or chronic pathology to ensure appropriate interventions.
2
Evaluate the statement regarding dry skin and easy bruising.
This is identified as an expected physiological change.
Aging causes a decrease in dermis thickness, reduced subcutaneous fat, and lower sebaceous gland activity, resulting in drier, more fragile skin.
3
Evaluate the statement regarding high-pitched hearing loss.
This is identified as an expected physiological change.
Presbycusis is a standard age-related sensorineural adaptation that progressively limits the ability to hear high-frequency tones.
4
Evaluate the statement regarding decreased chest expansion.
This is identified as an expected physiological change.
Age-related calcification of the rib cage and weakening of intercostal muscles naturally decrease pulmonary compliance and deep-breathing capacity.
5
Evaluate the statement about urinary leakage.
This is identified as a pathological finding requiring follow-up.
While bladder capacity decreases with age, actual urinary incontinence is never a normal physiological consequence of aging and is typically caused by infections, pelvic floor weakness, or neurological issues.

Question 251Question →

An orthopedic unit nurse is evaluating a client 36 hours after a closed reduction and intramedullary nailing of a right femoral shaft fracture. The client suddenly exhibits profound agitation, dyspnea, and a feeling of impending doom. Physical assessment reveals a petechial rash on the anterior chest, distended neck veins, and severe diaphoresis. Vital signs are: blood pressure 86/52 mm Hg, heart rate 134 bpm, respiratory rate 36/min, and SpO2 84% on room air. Arterial blood gas (ABG) analysis indicates a pH of 7.54, PaCO2 of 25 mm Hg, HCO3 of 22 mEq/L, and PaO2 of 52 mm Hg. Based on this clinical presentation, which action should the nurse perform immediately?

Show answer & explanation

Answer: Apply high-flow oxygen via a non-rebreather mask and anticipate the need for mechanical ventilation.

Answer

Apply high-flow oxygen via a non-rebreather mask and anticipate the need for mechanical ventilation.
The client is exhibiting the classic triad of fat embolism syndrome (FES): respiratory distress, neurological changes (agitation), and a petechial rash following a long-bone fracture. The severe hypoxemia (PaO2 52 mm Hg) and hemodynamic instability require immediate airway and breathing stabilization. High-flow oxygen is the absolute priority to address the profound hypoxia before proceeding with further diagnostics or secondary treatments.

Step-by-Step Solution

1
Analyze the client's history and physical assessment findings.
The client has a recent long-bone fracture and presents with the classic triad of fat embolism syndrome (FES): neurological changes (agitation), respiratory distress, and a petechial rash.
Identifying the underlying pathology is crucial for anticipating complications and directing care.
2
Interpret the vital signs and arterial blood gas (ABG) values.
The client has severe hypoxemia (PaO2 52 mm Hg, SpO2 84%), hypotension, and uncompensated respiratory alkalosis (pH 7.54, PaCO2 25 mm Hg) caused by extreme hyperventilation.
Accurate interpretation determines the severity of the respiratory failure and hemodynamic compromise.
3
Evaluate the hemodynamic state using physical signs.
Distended neck veins combined with hypotension indicate right ventricular strain (obstructive shock) secondary to pulmonary vascular occlusion, ruling out hypovolemic shock.
Differentiating the type of shock prevents harmful interventions, such as inappropriate rapid fluid loading.
4
Apply prioritization principles (Airway, Breathing, Circulation).
The most immediate life-threatening issue is profound hypoxia; therefore, administering high-flow oxygen is the priority action over diagnostics or medication administration.
Basic life support principles dictate that oxygenation and ventilation must be secured before confirming the diagnosis or addressing other imbalances.

Question 252Question →

A nurse is conducting a comprehensive admission assessment for an 82-year-old client on a medical-surgical unit. Which of the following assessment findings should the nurse interpret as expected age-related physiological changes? Select all that apply.

Select all that apply

Show answer & explanation

Answer: The client reports a diminished sensation of thirst despite minimal fluid intake over several hours.; The client exhibits a widened pulse pressure with a slight increase in resting systolic blood pressure.; The client requires more ambient light to read and reports an increased sensitivity to glare.

Answer

The expected age-related changes are a diminished sensation of thirst, a widened pulse pressure with a slight increase in systolic blood pressure, and a need for more ambient light with increased sensitivity to glare.
Expected physiological changes of aging include a decreased sensitivity of the thirst mechanism in the hypothalamus, stiffening of the large arteries which leads to a widened pulse pressure and slightly higher systolic blood pressure, and changes in the lens of the eye that decrease light transmission and scatter light, causing glare sensitivity.

Step-by-Step Solution

1
Evaluate each assessment finding to determine if it is a normal physiological adaptation to senescence or an acute pathological condition.
Categorize the findings into expected changes versus unexpected disease processes.
Nurses must differentiate between harmless aging changes and symptoms requiring medical intervention.
2
Identify the cardiovascular, sensory, and regulatory changes that naturally occur over time.
Recognize that decreased thirst (hypothalamic change), widened pulse pressure (arterial stiffening), and glare sensitivity (lens opacity) are normal adaptations.
These structural and functional declines are universal and anticipated in older adults.
3
Identify the findings that represent acute or progressive pathology.
Recognize that sudden incontinence, acute delirium, and loss of central vision indicate underlying disease.
Assuming abnormal symptoms are a normal part of aging can lead to a failure to rescue and severe client harm.

Question 253Question →

A nurse is preparing to administer an intravenous (IV) push medication through a Y-site port on a client's active continuous IV infusion line. Which of the following is the priority nursing action before proceeding with the administration?

Show answer & explanation

Answer: Verify the compatibility of the IV push medication with the continuous infusion fluid.

Answer

The priority action is to verify the compatibility of the IV push medication with the continuous infusion fluid.
Verifying compatibility is the absolute first step when preparing to administer an IV push medication into an existing continuous infusion. If medications are incompatible, they can form a precipitate, inactivate one another, or cause a severe adverse reaction. This safety check dictates whether the medication can be safely given through the existing line or if alternative access is required, meaning it must precede all physical procedural steps.

Step-by-Step Solution

1
Identify the proposed route and existing therapies.
The client has a continuous IV infusion and requires an IV push medication via the Y-site.
Understanding the IV setup is necessary to identify potential medication interaction risks.
2
Recall the principles of safe intravenous medication administration.
Medications given in the same IV line can interact, causing precipitates or drug inactivation.
Chemical and physical incompatibilities pose a significant, immediate risk to patient safety.
3
Determine the priority sequence of actions.
Checking drug compatibility must occur before preparing the medication or interacting with the client's IV site.
If the medications are incompatible, a separate IV access may be required, making physical procedural steps on the current line irrelevant or dangerous.

Key Concept

Question 254Question →

A client diagnosed with severe sepsis has a double-lumen central venous catheter (CVC). The proximal lumen is dedicated to a continuous infusion of total parenteral nutrition (TPN). The distal lumen is delivering a continuous infusion of norepinephrine to maintain systemic vascular resistance. During the shift, the client's mean arterial pressure drops to 54 mm Hg54\text{ mm Hg}. The provider verbally prescribes an immediate 500 mL500\text{ mL} intravenous bolus of lactated Ringer's solution and 100 mg100\text{ mg} of hydrocortisone sodium succinate via intravenous push. Which action by the nurse demonstrates the safest administration of these prescribed therapies?

Show answer & explanation

Answer: Establish a new peripheral intravenous catheter to administer the fluid bolus and the intravenous push medication.

Answer

Establish a new peripheral intravenous catheter to administer the fluid bolus and the intravenous push medication.
The correct answer is to establish a new peripheral intravenous catheter. When managing a critically ill client with a multi-lumen central line, the nurse must adhere to strict parenteral safety rules regardless of the emergency. The proximal lumen is infusing total parenteral nutrition (TPN), which requires a strictly dedicated line; it must never be used for fluid boluses, blood products, or intravenous push medications due to the high risk of infection and chemical incompatibility. The distal lumen is infusing norepinephrine, a potent continuous vasopressor. Connecting a rapid fluid bolus to this line, or flushing the line to administer an intravenous push medication, will rapidly flush the residual norepinephrine residing in the intravenous tubing's dead space directly into the client's central circulation. This unintentional bolus can cause a lethal hypertensive crisis and fatal arrhythmias. Additionally, temporarily pausing the norepinephrine in a severely hypotensive client (MAP of 54 mm Hg) will cause immediate cardiovascular collapse. Therefore, the only safe action is to rapidly establish a new peripheral intravenous access site for the new prescriptions.

Step-by-Step Solution

1
Evaluate the current utilization and safety constraints of the central venous catheter lumens.
One lumen is dedicated to TPN, and the other is infusing a life-sustaining concentrated vasopressor (norepinephrine).
Safe parenteral administration requires assessing existing access for compatibility, infection control protocols, and hemodynamic safety before administering new emergency therapies.
2
Analyze the clinical safety of using the proximal TPN lumen.
The TPN lumen is strictly rejected for any other uses.
TPN lumens must be exclusively dedicated to parenteral nutrition due to the high risk of central line-associated bloodstream infections (CLABSI) and complex chemical incompatibilities that cause precipitation.
3
Analyze the clinical safety of using the distal vasopressor lumen.
The norepinephrine lumen cannot be used for rapid boluses, nor can it be paused for an intravenous push.
Bolusing fluid or rapidly flushing a line containing a concentrated vasopressor will rapidly force the residual medication in the intravenous tubing (dead space) into the client, causing a potentially lethal spike in blood pressure. Pausing the infusion is also contraindicated as it will immediately worsen the severe hypotensive shock.
4
Determine the safest alternative route for the emergency prescriptions.
A new peripheral intravenous line must be established immediately.
Despite the critical nature of the emergency and the presence of a central line, utilizing inappropriate central lumens poses immediate life-threatening risks. A new access point is the only physiological and pharmacologically safe route.

Key Concept

Central line lumen dedication, vasopressor administration safety, and the prevention of unintended medication boluses (speed shock).
Question 255Question →

A registered nurse is planning care for a 78-year-old client who is 1 day post-operative following a right total hip arthroplasty (posterior approach). Which basic care and comfort interventions should the nurse include in the client's plan of care? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Apply an abduction pillow between the client's legs when resting in bed.; Place a raised toilet seat over the commode for elimination needs.; Apply ice packs to the surgical site as a non-pharmacological comfort measure.

Answer

The correct interventions include applying an abduction pillow, using a raised toilet seat, and applying ice packs to the surgical site.
Appropriate basic care and comfort for a posterior approach total hip arthroplasty focuses on maintaining joint alignment and managing pain. Interventions must prevent adduction (using an abduction pillow) and prevent hip flexion greater than 90 degrees (using a raised toilet seat). Additionally, applying ice is a standard non-pharmacological comfort measure to reduce localized tissue swelling and pain.

Step-by-Step Solution

1
Identify the surgical procedure and approach.
The client had a right total hip arthroplasty via a posterior approach.
The surgical approach determines specific anatomical precautions (avoiding flexion > 90 degrees, adduction, and internal rotation).
2
Evaluate each intervention for adherence to posterior hip precautions and safe care principles.
Abduction pillows and raised toilet seats maintain proper alignment and prevent excessive flexion or adduction. Ice packs safely manage localized pain.
Maintaining joint stability and promoting comfort are primary goals of post-operative basic care.
3
Identify contraindicated actions related to positioning, delegation, and geriatric assessment.
Low chairs violate hip flexion precautions. Delegating initial skin assessment is outside the UAP's scope. Acute confusion is an abnormal pathological finding.
Recognizing unsafe practices prevents complications such as joint dislocation, missed skin breakdown, or failure to rescue a declining client.

Question 256Question →

A client arrives at the cardiac step-down unit after a diagnostic cardiac catheterization accessed through the right femoral artery. Which intervention must the nurse implement to reduce the risk of hemorrhage at the access site?

Show answer & explanation

Answer: Remind the client to maintain the right leg in a straight position.

Answer

Remind the client to maintain the right leg in a straight position.
Following a femoral artery cardiac catheterization, keeping the affected extremity straight is critical. This position minimizes tension and bending at the groin access site, allowing a stable clot to form and preventing severe hemorrhage or hematoma.

Step-by-Step Solution

1
Identify the procedure and the specific access site.
The client underwent a cardiac catheterization via the right femoral artery.
The anatomical location of the arterial puncture dictates specific post-procedure mobility restrictions.
2
Determine the primary physiological risk associated with this access site.
The femoral artery is a large vessel under high pressure, making hemorrhage and hematoma formation the greatest immediate risks.
Recognizing the high risk of bleeding guides the selection of protective nursing interventions.
3
Select the nursing intervention that directly prevents stress on the puncture site.
Keeping the right leg completely straight minimizes movement and flexion at the groin.
Maintaining the leg straight prevents disruption of the developing clot and reduces the risk of arterial bleeding.

Answer: Gradual difficulty hearing high-pitched consonant sounds during conversations in noisy environments.

Answer

Gradual difficulty hearing high-pitched consonant sounds during conversations in noisy environments.
Presbycusis is the most common sensory impairment in older adults. It involves a progressive, bilateral loss of high-frequency hearing, which makes it particularly difficult for the older adult to hear high-pitched consonants (like 's', 'th', 'f') and distinguish specific words in crowded or noisy environments. This is a normal physiological consequence of aging.

Step-by-Step Solution

1
Analyze the clinical requirement presented in the stem.
The nurse must correctly differentiate between normal physiological adaptations of aging (senescence) and acute pathological conditions.
Assuming abnormal symptoms are a normal part of aging can lead to a failure to rescue or delayed medical treatment.
2
Evaluate the auditory symptom presented in the options.
Identify that high-frequency hearing loss (presbycusis) is an expected age-related change.
Degeneration of the cochlea, auditory nerve, and inner ear structures naturally occurs as a person ages, resulting in presbycusis.
3
Evaluate the remaining clinical presentations.
Identify delirium, urinary incontinence, and symptomatic bradycardia as acute pathological findings.
These presentations indicate acute physiological instability (infection, pelvic floor weakness, and decreased cardiac output) that demand nursing intervention and provider notification.

Key Concept

Differentiating expected physiological adaptations of aging from pathological disease processes.

A home care nurse is evaluating the self-care management of an older adult client recovering from a right total hip arthroplasty (posterior approach). Which action or statement by the client indicates an accurate understanding of their self-care instructions?

Show answer & explanation

Answer: The client uses a long-handled reacher device to retrieve a dropped item from the floor.

Answer

The client correctly uses a long-handled reacher device to retrieve dropped items, which maintains necessary hip precautions.
Clients recovering from a posterior approach total hip arthroplasty must avoid hip flexion greater than 90 degrees to prevent dislocation. Using assistive devices like a long-handled reacher allows the client to perform activities of daily living (ADLs) independently without compromising the new joint.

Step-by-Step Solution

1
Identify the client's surgical procedure and the associated anatomical risks.
The client had a right total hip arthroplasty via a posterior approach, which carries a high risk of dislocation if the hip is flexed beyond 90 degrees.
Understanding the specific surgical approach dictates which movements are contraindicated during independent self-care.
2
Evaluate each client action or statement for safety and accuracy regarding self-care and general health maintenance.
Leaning forward to put on socks violates hip precautions. Misidentifying rehab as primary prevention and dismissing sudden incontinence as normal aging are both incorrect health beliefs.
Distinguishing safe, correct health behaviors from unsafe or misguided ones is necessary to determine if self-care teaching was effective.
3
Select the option that demonstrates safe, independent adherence to the prescribed restrictions.
Using a reacher device allows the client to retrieve items without bending the hip past 90 degrees.
Adaptive equipment is a cornerstone of safe self-care for clients with movement restrictions.

Which of the following interventions should the nurse implement to mitigate the risk of severe physiological deterioration? (Select all that apply.)

Select all that apply

Show answer & explanation

Answer: Initiate a rapid intravenous infusion of warmed isotonic crystalloid fluids.; Prepare for the emergent administration of uncrossmatched type O-negative packed red blood cells.; Defer non-essential nursing care such as a complete bed bath to cluster activities.

Answer

The correct interventions are initiating a rapid infusion of warmed isotonic crystalloids, preparing for the administration of uncrossmatched type O-negative packed red blood cells, and deferring non-essential nursing care to cluster activities.
The client is experiencing profound hypovolemic (hemorrhagic) shock due to a severe pelvic fracture, evidenced by severe hypotension, tachycardia, a low CVP, and oliguria. Immediate fluid resuscitation with rapid, warmed isotonic crystalloids and uncrossmatched O-negative blood is essential to restore intravascular volume and tissue perfusion. Additionally, the client is in a state of severe mixed acidosis and hypoxemia; deferring non-essential physical care minimizes oxygen consumption and metabolic demand, protecting the precarious supply-demand balance.

Step-by-Step Solution

1
Analyze the client's vital signs, hemodynamics, and urine output.
The client exhibits profound hypotension (78/42 mm Hg78/42 \text{ mm Hg}), marked tachycardia (138 beats/min138 \text{ beats/min}), a critically low CVP (1 mm Hg1 \text{ mm Hg}), and severe oliguria (10 mL/hr10 \text{ mL/hr}).
These findings collectively indicate class IV hypovolemic (hemorrhagic) shock secondary to the severe pelvic fracture, requiring immediate intravascular volume replacement with crystalloids and blood products.
2
Interpret the arterial blood gas (ABG) results in the context of the client's injuries.
The ABG reveals a severe mixed acidosis: respiratory acidosis from the pulmonary contusion (PaCO2\text{PaCO}_2 54 mm Hg54 \text{ mm Hg}) and metabolic (lactic) acidosis from systemic tissue hypoperfusion (HCO3−\text{HCO}_3^- 15 mEq/L15 \text{ mEq/L}).
Mixed acidosis confirms life-threatening physiological decompensation. Treatment must focus on restoring perfusion to clear lactic acid, rather than administering bicarbonate which would worsen the respiratory component.
3
Evaluate the impact of nursing interventions on oxygen supply and demand.
Routine activities (like bed baths) and extreme positioning (like high-Fowler's) increase oxygen consumption and decrease venous return.
In states of severe shock and hypoxemia, nursing care must be clustered and deferred to minimize myocardial oxygen demand and preserve cardiac output, necessitating the client remain supine.

A bedside liver biopsy has just been completed for a client on the medical-surgical unit. Which position should the nurse assist the client into immediately after the procedure to minimize the risk of hemorrhage from the puncture site?

Show answer & explanation

Answer: Right side-lying position with a folded towel placed under the puncture site

Answer

The client should be placed in a right side-lying position with a folded towel placed under the puncture site.
The liver is a highly vascular organ, making hemorrhage the most significant risk following a liver biopsy. Assisting the client into a right side-lying position ensures that the weight of the client's own body applies direct pressure to the puncture site on the right side, which effectively tamponades the area and promotes hemostasis.

Step-by-Step Solution

1
Identify the anatomical location involved in the procedure.
The liver is located in the right upper quadrant of the abdomen.
Knowing the anatomy determines where pressure must be applied.
2
Identify the primary complication associated with a percutaneous liver biopsy.
Hemorrhage is the greatest risk because the liver is a highly vascular organ.
Understanding the primary post-procedure risk guides the appropriate preventive nursing intervention.
3
Select the position that applies direct pressure to the right upper quadrant.
The right side-lying position effectively compresses the biopsy site.
Direct pressure promotes hemostasis and reduces the potential for bleeding.
