A nursing supervisor is evaluating task delegation on a medical-surgical unit. What specific medication administration task is appropriate for the charge nurse to delegate to the practical nurse?

Show answer & explanation

Answer: Providing a scheduled subcutaneous dose of enoxaparin to a stable client on postoperative day two.

Answer

Providing a scheduled subcutaneous dose of enoxaparin to a stable client on postoperative day two.
The administration of a scheduled subcutaneous injection to a clinically stable client is a predictable, routine procedure that safely falls within the established scope of practice for a practical nurse.

Step-by-Step Solution

1
Evaluate each assigned task to determine if it requires advanced clinical judgment or restricted administration routes.
Intravenous push medications and managing acutely unstable clients are restricted to the registered nurse scope of practice.
Ensures adherence to legal practice acts and maintains baseline client safety.
2
Assess the clinical appropriateness of the remaining tasks based on general pharmacological principles.
Administering live vaccines to pregnant clients and bypassing standard two-identifier medication protocols are demonstrably unsafe clinical practices.
Prevents severe adverse patient outcomes from contraindicated therapies and identification errors.
3
Identify the task that is both legally delegable and clinically safe.
The administration of a scheduled subcutaneous anticoagulant to a stable postoperative client is identified as the correct action.
This represents a predictable, routine procedure perfectly suited for a practical nurse.

A practical nurse is assigned to care for an adult client who is receiving intravenous fluid therapy for fluid volume deficit following an episode of gastroenteritis. The client has a heart rate of 108108 bpm and a blood pressure of 98/6098/60 mmHg. The healthcare provider has prescribed 500500 mL of 0.9%0.9\% sodium chloride to infuse over 66 hours. The primary intravenous tubing has a drop factor of 2020 gtt/mL. At how many drops per minute (gtt/min) should the infusion be regulated? Record the answer to the nearest whole number. Do not include units in the answer.

Show answer & explanation

Answer: 28

Answer

28
The correct drip rate is calculated by multiplying the total volume to be infused (500500 mL) by the administration set's drop factor (2020 gtt/mL) to determine the total number of drops. This total (10,00010,000 drops) is then divided by the total time in minutes (360360 minutes). The resulting quotient of 27.777...27.777... is rounded to the nearest whole number, yielding a final regulatory rate of 2828 drops per minute.

Step-by-Step Solution

1
Convert the total infusion time from hours to minutes.
6 hours×60 minutes/hour=360 minutes6 \text{ hours} \times 60 \text{ minutes/hour} = 360 \text{ minutes}
The standard intravenous drip rate formula requires the time variable to be expressed in minutes.
2
Apply the standard intravenous drip rate formula.
500 mL×20 gtt/mL360 minutes=27.777... gtt/min\frac{500 \text{ mL} \times 20 \text{ gtt/mL}}{360 \text{ minutes}} = 27.777... \text{ gtt/min}
This formula determines the number of drops infused per minute based on the prescribed volume, the tubing's specific drop factor, and the total duration.
3
Round the calculated rate to the nearest whole drop.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is: repositioning the client, assessing vital signs, administering oxygen, escalating to the RN, and documenting the event.
In any acute physiological crisis, the practical nurse must prioritize actions based on the ABCs (Airway, Breathing, Circulation) and the nursing process. The immediate priority is to facilitate breathing by repositioning the client into a high-Fowler's position. Next, rapid assessment of vital signs provides the necessary data to safely implement a PRN oxygen order. Once the client is temporarily stabilized with these initial measures, escalating the situation to the registered nurse ensures advanced care for a potential pulmonary embolism. Documentation is always the final step after client safety is secured.

Step-by-Step Solution

1
Reposition the client into a high-Fowler's alignment.
Maximizes lung expansion.
Addresses the immediate 'Breathing' component of the ABCs.
2
Measure the current oxygen saturation and vital signs.
Provides objective clinical data.
Guides further immediate interventions and establishes a baseline.
3
Initiate prescribed PRN supplemental oxygen therapy.
Increases circulating oxygen levels.
Treats the identified hypoxia based on assessment data.
4
Communicate the critical findings to the supervising registered nurse.
Escalates care for a potential pulmonary embolism.
Ensures the client receives advanced medical assessment.
5

Question 465Question →

During morning rounds, a practical nurse evaluates a 7171-year-old client who takes oral warfarin for atrial fibrillation. The client's most recent laboratory report reveals an International Normalized Ratio (INR) of 5.85.8. The current vital signs show a heart rate of 112112 beats per minute and a blood pressure of 92/56 mm Hg92/56\text{ mm Hg}. The client reports feeling unusually fatigued and dizzy when sitting up. What is the priority action for the nurse?

Show answer & explanation

Answer: Instruct the client to remain in bed and immediately report the findings to the registered nurse.

Answer

The priority action is to instruct the client to remain in bed for safety and immediately report the critical laboratory value and borderline vital signs to the registered nurse.
An INR of 5.85.8 is critically elevated. When combined with tachycardia, hypotension, and dizziness, this strongly suggests acute internal bleeding. The practical nurse's priority is to minimize injury risk by keeping the client in bed and to immediately escalate these critical findings to the registered nurse for urgent medical intervention.

Step-by-Step Solution

1
Analyze the laboratory value.
An INR of 5.85.8 is recognized as critically high, placing the client at severe risk for hemorrhage.
The normal therapeutic INR range for atrial fibrillation is typically 2.02.0 to 3.03.0.
2
Evaluate the current vital signs and client symptoms.
Tachycardia (112112 bpm), hypotension (92/56 mm Hg92/56\text{ mm Hg}), and dizziness are identified.
These findings represent early clinical indicators of potential internal bleeding and impending hypovolemic shock.
3
Determine the priority nursing action within the practical nurse scope of practice.
The nurse must ensure immediate client safety by maintaining bed rest and escalating the findings.
The client requires urgent medical intervention and advanced assessment by a registered nurse or provider that cannot be delayed.

Question 466Question →

A practical nurse (PN) enters the room of a client with type 1 diabetes mellitus. The client is pale, diaphoretic, and states, 'I feel very shaky.' The PN checks the capillary blood glucose, which is 42 mg/dL (2.3 mmol/L). The client is conscious and able to swallow. In what order should the PN perform the following actions? (Arrange the items in the correct sequence from first to last.)

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first treat the hypoglycemia with a fast-acting carbohydrate, wait 15 minutes, recheck the blood glucose, provide a stabilizing snack, and finally document the event.
The 'Rule of 15' is the standard evidence-based protocol for managing hypoglycemia in a conscious client. It dictates administering 15 grams of fast-acting carbohydrates, waiting 15 minutes, and rechecking the blood glucose. Once the glucose is above 70 mg/dL, a complex carbohydrate and protein snack is given to maintain stability, followed by accurate documentation of the entire event.

Step-by-Step Solution

1
Administer 15 grams of a fast-acting simple carbohydrate.
The client receives an immediate source of glucose.
Symptomatic hypoglycemia is an acute emergency. A conscious client who can swallow should immediately receive 15 grams of simple carbohydrates to rapidly increase blood sugar.
2
Wait 15 minutes.
Time is given for digestion and absorption.
It takes approximately 15 minutes for simple carbohydrates to absorb and affect the capillary blood glucose level.
3
Reassess the capillary blood glucose level.
The effectiveness of the initial intervention is measured.
Checking the glucose confirms if it has risen above 70 mg/dL or if the 15-minute rule needs to be repeated.
4
Provide a complex carbohydrate and protein snack.
The client's blood sugar is stabilized.
Simple sugars metabolize quickly. A complex carbohydrate and protein provide sustained energy to prevent recurrent hypoglycemia.
5
Document the event and response.
The medical record is accurately updated.
Documentation occurs after the client is safe and stabilized to ensure an accurate record of the emergency and the client's response.

Question 467Question →

A practical nurse (PN) is monitoring a client who underwent a percutaneous liver biopsy 22 hours ago. The client is currently positioned on their right side. The client reports mild lightheadedness. The PN notes that the client's heart rate has increased from 8080 to 108108 beats/minute, and their blood pressure has decreased from 126/78126/78 to 108/68108/68 mmHg over the past hour. The client's skin feels slightly cool and clammy.

Which of the following is the most appropriate initial action for the PN to take?

Show answer & explanation

Answer: Notify the registered nurse (RN) immediately about the changes in the client's condition.

Answer

Notify the registered nurse (RN) immediately about the changes in the client's condition.
The client's increasing heart rate, decreasing blood pressure, lightheadedness, and cool, clammy skin are classic early signs of hypovolemic shock, likely due to internal bleeding from the highly vascular liver biopsy site. In the role of the PN, recognizing these critical changes and escalating them immediately to the RN is the absolute priority to ensure the client receives rapid medical intervention and to reduce the risk of potential severe harm.

Step-by-Step Solution

1
Analyze the client's clinical presentation and vital sign trends.
The client has tachycardia (108108 beats/minute), narrowing pulse pressure with hypotension (108/68108/68 mmHg), lightheadedness, and cool, clammy skin.
Identifying abnormal assessment findings is the first step in recognizing post-procedural complications.
2
Correlate the findings with the recent percutaneous liver biopsy.
These symptoms strongly suggest internal hemorrhage and early hypovolemic shock, a known risk following a highly vascular procedure like a liver biopsy.
Connecting the symptoms to the procedure helps determine the severity and urgency of the situation.
3
Determine the appropriate scope of practice and prioritization.
The PN must recognize this as a medical emergency and immediately notify the RN, who can collaborate with the healthcare provider for advanced interventions.
Timely escalation is critical to patient safety and falls directly within the PN's responsibility for risk reduction.

Question 468Question →

A client is being monitored on the surgical unit 24 hours after a thoracotomy with a closed chest drainage system in place. Which assessment findings should the practical nurse immediately report to the registered nurse as indicators of a developing tension pneumothorax? Select all that apply.

Select all that apply

Show answer & explanation

Answer: Tracheal deviation away from the operative side; Sudden decrease in blood pressure with severe tachycardia; Asymmetrical chest wall movement during inspiration

Answer

The findings that indicate a developing tension pneumothorax are tracheal deviation away from the operative side, sudden decrease in blood pressure with severe tachycardia, and asymmetrical chest wall movement during inspiration.
A tension pneumothorax is a medical emergency where air accumulates in the pleural space with each breath but cannot escape. The rising intrathoracic pressure collapses the affected lung (causing asymmetrical chest movement) and shifts the mediastinal structures toward the unaffected side (causing tracheal deviation). The immense pressure also compresses the heart and superior/inferior vena cava, drastically reducing venous return and cardiac output, which manifests rapidly as severe hypotension and compensatory tachycardia.

Step-by-Step Solution

1
Analyze the client's clinical scenario.
The client is 24 hours post-thoracotomy with a closed chest drainage system, putting them at risk for respiratory complications such as a tension pneumothorax if the system malfunctions or air leaks rapidly into the pleural space.
Understanding the client's surgical history establishes the baseline risks for acute decompensation.
2
Identify the pathophysiology and classic signs of a tension pneumothorax.
A tension pneumothorax involves trapped air in the pleural space that causes mediastinal shift (tracheal deviation), cardiovascular compression (hypotension, tachycardia), and collapsed lung (asymmetrical chest movement, absent breath sounds).
Matching physiological concepts to clinical manifestations is required to evaluate the assessment data.
3
Evaluate each assessment finding against expected post-operative baselines versus emergency indicators.
Tracheal deviation, hemodynamic collapse, and asymmetrical chest movement are critical emergencies. Gentle bubbling in the suction chamber, 45 mL of drainage, and incisional pain are expected post-thoracotomy findings.
Differentiating between expected post-operative data and signs of acute physiological failure ensures safe and timely reporting to the registered nurse.

Key Concept

Tension pneumothorax is a life-threatening complication characterized by air trapping in the pleural space, leading to mediastinal shift, asymmetrical chest expansion, and severe hemodynamic compromise (hypotension and tachycardia) due to compressed great vessels.

A practical nurse is preparing to administer a combined dose of NPH insulin and regular insulin in a single syringe for a client with diabetes mellitus. In what order should the nurse perform the following steps to safely mix these medications?

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first inject air into the NPH vial, then inject air into the regular vial, withdraw the regular insulin, and finally withdraw the NPH insulin.
The established standard for mixing NPH (cloudy) and regular (clear) insulins is to inject air into the cloudy vial, inject air into the clear vial, withdraw the clear insulin, and then withdraw the cloudy insulin. This strict sequence ensures that the rapid or short-acting insulin vial is never contaminated with intermediate-acting insulin, maintaining the purity and expected pharmacokinetics of the clear insulin for future use.

Step-by-Step Solution

1
Inject air into the NPH (cloudy) vial.
The NPH vial is pressurized for later withdrawal.
Pressurizing the vial prevents a vacuum from forming, making withdrawal easier, while avoiding contamination by the clear insulin at this early stage.
2
Inject air into the regular (clear) vial.
The regular insulin vial is pressurized.
This prepares the clear insulin vial for immediate withdrawal.
3
Withdraw the regular (clear) insulin.
The precise dose of short-acting insulin is drawn into the syringe.
Drawing clear before cloudy prevents contaminating the short-acting vial with intermediate-acting insulin, which could dangerously alter its properties for future doses.
4
Withdraw the NPH (cloudy) insulin.
The correct combined volume is achieved in the syringe.
This completes the mixture safely. The nurse must be careful not to push any regular insulin into the NPH vial during this final step.

Key Concept

When mixing insulins, the standard protocol is 'clear before cloudy' to prevent the contamination of short-acting insulin with intermediate-acting insulin.
Question 470Question →

A practical nurse (PN) is assigned to care for a 78-year-old client with a history of chronic kidney disease who is receiving a continuous intravenous (IV) infusion of normal saline at 125 mL/hr. During hourly rounds, the client suddenly becomes restless, repeatedly asks where they are, and exhibits a respiratory rate of 26 breaths/min with a heart rate of 104 beats/min. Which action should the PN take FIRST?

Show answer & explanation

Answer: Elevate the head of the bed and measure the client's oxygen saturation.

Answer

The correct action is to elevate the head of the bed and measure the client's oxygen saturation.
Restlessness and acute confusion in an older adult, especially when accompanied by an increased respiratory rate and heart rate during continuous IV fluid therapy, are early signs of hypoxia secondary to fluid volume overload. Elevating the head of the bed rapidly promotes lung expansion, and measuring oxygen saturation provides immediate, critical data regarding the client's respiratory status before notifying the registered nurse (RN).

Step-by-Step Solution

1
Analyze the client's presentation and medical history.
The client is elderly, has chronic kidney disease, is receiving continuous IV fluids, and presents with new-onset restlessness, confusion, tachypnea, and tachycardia.
Identifying risk factors (kidney disease, IV fluids) combined with acute symptom changes is necessary to determine the underlying physiological problem.
2
Correlate the assessment findings with potential complications.
The findings strongly suggest fluid volume overload leading to pulmonary congestion and subsequent hypoxia.
Restlessness and acute confusion in older adults are often the earliest signs of poor oxygenation, rather than a primary psychological issue.
3
Prioritize the nursing interventions using the ABC (Airway, Breathing, Circulation) framework.
Facilitating breathing by elevating the head of the bed and obtaining an oxygen saturation reading becomes the absolute priority.
Immediate physical positioning improves respiratory mechanics, and pulse oximetry provides actionable data to report to the registered nurse (RN).

Question 471Question →

While conducting a morning assessment on a surgical unit, a licensed practical nurse evaluates a client who is 24 hours24\text{ hours} post-subtotal thyroidectomy. The electronic health record displays a newly resulted serum calcium level of 7.1 mg/dL7.1\text{ mg/dL}. At the bedside, the client describes a "pins and needles" sensation around their lips and fingers. Assessment reveals a heart rate of 104 beats/min104\text{ beats/min}, a blood pressure of 96/60 mmHg96/60\text{ mmHg}, and mild facial muscle twitching. What is the priority action for the nurse to take?

Show answer & explanation

Answer: Report the assessment data to the supervising registered nurse and verify that emergency airway equipment is present.

Answer

The priority action is to report the critical findings to the supervising registered nurse and ensure emergency airway equipment is immediately accessible.
A subtotal thyroidectomy carries a high risk of accidental injury to the parathyroid glands, leading to acute hypocalcemia. A serum calcium level of 7.1 mg/dL7.1\text{ mg/dL}, combined with perioral tingling and facial twitching (Chvostek's sign), indicates impending tetany and possible laryngospasm. The practical nurse must immediately report these critical findings to the registered nurse for intravenous calcium administration and verify that emergency airway equipment is available to prevent respiratory arrest.

Step-by-Step Solution

1
Analyze the laboratory and assessment data.
The serum calcium level of 7.1 mg/dL7.1\text{ mg/dL} is critically low (normal is generally 8.58.5 to 10.5 mg/dL10.5\text{ mg/dL}). The client is exhibiting perioral paresthesia, facial twitching, and borderline unstable vital signs.
Identifying hypocalcemia is essential because it is a life-threatening complication of thyroidectomy caused by accidental damage to or removal of the parathyroid glands.
2
Determine the potential complications of the client's current condition.
Severe symptomatic hypocalcemia can rapidly lead to tetany, cardiac dysrhythmias, and laryngospasm (which closes the airway).
Recognizing laryngospasm as the most imminent threat dictates that airway protection is the highest priority.
3
Select the action that best mitigates the risk within the practical nursing scope.
The practical nurse must escalate the situation to the registered nurse (who can administer intravenous calcium) while verifying a tracheostomy tray or emergency airway kit is at the bedside.
Operating within the scope of practice ensures client safety during an acute physiological crisis.

Arrange the actions from first to last.

Drag items to arrange them in the correct order

Show answer & explanation

Answer

The correct sequence is to first stay with the client and call for assistance, then position the client in a low Fowler's position with knees flexed, followed by covering the protruding organs with sterile, saline-moistened dressings, and finally obtaining vital signs.
The correct sequence prioritizes immediate client safety, prevention of further evisceration, tissue protection, and systemic monitoring. Calling for assistance while staying with the client ensures help arrives with necessary supplies without leaving the client unsafe. Positioning in low Fowler's with bent knees immediately reduces tension on the abdominal suture line. Covering the protruding bowel with sterile, saline-moistened dressings prevents necrosis and infection. Finally, monitoring vital signs assesses for complications such as hypovolemic shock while awaiting emergency surgical intervention.

Step-by-Step Solution

1
Ensure immediate safety and obtain assistance.
The nurse stays with the client and calls for help.
Leaving the client could result in further injury or panic; another staff member must bring sterile supplies to the room while the nurse remains at the bedside.
2
Minimize abdominal tension.
The client is placed in a low Fowler's position with knees flexed.
This physical position directly relaxes the abdominal muscles and prevents further protrusion of the bowel.
3
Protect the eviscerated tissue.
The protruding organs are covered with sterile, saline-soaked dressings.
Exposed bowel can quickly become necrotic if it dries out. A moist, sterile environment prevents tissue damage and infection.
4
Assess systemic status.
Vital signs are obtained and continuously monitored.
Wound evisceration can lead to rapid fluid shifts and hypovolemic shock, requiring close hemodynamic monitoring while awaiting emergency surgical intervention.

Question 473Question →

While reviewing the electronic health record of a client diagnosed with a severe infection, a practical nurse observes a significant change in the client's laboratory results. The morning serum creatinine has increased to 2.9 mg/dL (reference range: 0.6–1.2 mg/dL) from a baseline of 1.0 mg/dL upon admission. The client is prescribed intravenous gentamicin, and the next dose is scheduled to be administered in 15 minutes. Which action should the nurse take?

Show answer & explanation

Answer: Withhold the upcoming dose of the medication and immediately communicate the laboratory findings to the registered nurse.

Answer

The correct action is to withhold the upcoming dose of the medication and immediately communicate the laboratory findings to the registered nurse.
The correct action is to withhold the medication and report the findings. Gentamicin is an aminoglycoside antibiotic that is notoriously nephrotoxic. The client's serum creatinine level has abruptly increased from 1.0 mg/dL to 2.9 mg/dL, strongly indicating acute kidney injury. Giving another dose of gentamicin could cause further, potentially irreversible, renal damage. Within the scope of practice, the practical nurse must recognize this critical change, withhold the harmful agent, and escalate the information to the registered nurse or provider for a change in the treatment plan.

Step-by-Step Solution

1
Analyze the client's laboratory results.
The serum creatinine is 2.9 mg/dL, which is significantly higher than the normal range (0.6-1.2 mg/dL) and the baseline of 1.0 mg/dL.
Identifying abnormal laboratory values is critical before administering medications, especially those cleared by the kidneys.
2
Identify the properties of the prescribed medication.
Gentamicin is an aminoglycoside antibiotic known for its potential nephrotoxic side effects.
Understanding the adverse effects of medications helps the nurse anticipate complications.
3
Determine the appropriate nursing intervention based on the practical nurse scope of practice.
The nurse must withhold the nephrotoxic drug and escalate the critical laboratory finding to the registered nurse or healthcare provider.
Administering the medication could worsen kidney injury, and the practical nurse must report significant changes in client status to the supervising RN.

Question 474Question →

During afternoon rounds, a client who underwent a percutaneous liver biopsy three hours ago reports feeling unusually thirsty and lightheaded. The practical nurse obtains the following vital signs: heart rate 114 bpm, blood pressure 96/58 mm Hg, and respiratory rate 22 breaths/min. The client's baseline blood pressure prior to the procedure was 128/74 mm Hg. Based on these findings, which action should the nurse take first?

Show answer & explanation

Answer: Notify the supervising registered nurse immediately.

Answer

The correct action is to notify the supervising registered nurse immediately.
The correct response demonstrates the practical nurse's ability to recognize a life-threatening physiological adaptation (internal bleeding leading to hypovolemic shock) and take the appropriate priority action within their scope of practice, which is immediate escalation to the registered nurse.

Step-by-Step Solution

1
Analyze the client's presenting symptoms and vital signs against their baseline.
The client has developed tachycardia (114 bpm), hypotension (drop from 128/74 to 96/58), thirst, and lightheadedness.
Identifying acute changes from baseline is essential for early recognition of postoperative complications.
2
Correlate the findings with the recent procedure (liver biopsy).
The liver is highly vascular, making internal hemorrhage a primary risk following a biopsy. The symptoms directly align with hypovolemic shock.
Connecting physiological data to the client's clinical history helps determine the severity and nature of the emergency.
3
Determine the priority nursing action based on the practical nurse scope of practice.
The most critical action is to immediately escalate the findings to the registered nurse or healthcare provider.
Acute physiological decompensation requires immediate advanced intervention (such as IV fluids, blood products, or surgery) which must be initiated by the RN or provider.

A practical nurse is preparing to administer a prescribed dose of oral amoxicillin suspension to a pediatric client who weighs 14 kg14 \text{ kg}. The provider's prescription states: amoxicillin 40 mg/kg/day40 \text{ mg/kg/day} by mouth divided into two equal doses every 1212 hours. The pharmacy dispenses amoxicillin suspension at a concentration of 250 mg/5 mL250 \text{ mg}/5 \text{ mL}. How many mL\text{mL} should the nurse administer per dose? (Record your answer to the nearest tenth. Do not include units in your answer.)

Show answer & explanation

Answer: 5.6

Answer

The nurse should administer 5.6 mL per dose.
To ensure safe medication administration, the nurse must accurately convert the prescribed weight-based parameter into a measurable fluid volume. By calculating the total daily dose (560 mg560 \text{ mg}), dividing it into the specified two doses (280 mg280 \text{ mg} each), and applying the concentration formula (DesiredHave×Volume\frac{\text{Desired}}{\text{Have}} \times \text{Volume}), the correct verifiable dose is 5.6 mL5.6 \text{ mL}.

Step-by-Step Solution

1
Determine the total daily dose in milligrams based on the client's weight.
14 kg×40 mg/kg=560 mg/day14 \text{ kg} \times 40 \text{ mg/kg} = 560 \text{ mg/day}
Weight-based prescriptions require calculating the total 24-hour medication allowance before determining individual dose amounts.
2
Determine the individual dose amount in milligrams.
560 mg÷2=280 mg/dose560 \text{ mg} \div 2 = 280 \text{ mg/dose}
The prescription specifies that the total daily amount must be divided into two equal doses administered every 12 hours.
3
Calculate the liquid volume to administer per dose using the supplied concentration.
(280 mg250 mg)×5 mL=5.6 mL(\frac{280 \text{ mg}}{250 \text{ mg}}) \times 5 \text{ mL} = 5.6 \text{ mL}
This converts the required milligram dose into the measurable milliliter volume provided by the pharmacy.

Simultaneously, the electronic health record alerts the nurse to a newly resulted serum hemoglobin level of 7.37.3 g/dL. Based on these clinical findings, what is the most appropriate initial action?

Show answer & explanation

Answer: Immediately alert the registered nurse about the client's vital signs and the recent blood work.

Answer

Immediately alert the registered nurse about the client's vital signs and the recent blood work.
The correct response demonstrates the practical nurse's ability to identify a high-risk postoperative complication (hemorrhage leading to hypovolemic shock) by recognizing the combination of tachycardia, borderline hypotension, and a critical hemoglobin level. Immediate escalation to the registered nurse is the safest and most appropriate action within the LPN/LVN scope of practice to reduce client risk.

Step-by-Step Solution

1
Analyze the vital signs in the context of the surgical procedure.
The heart rate of 114114 beats/minute and blood pressure of 96/5896/58 mm Hg indicate tachycardia and borderline hypotension, which are early signs of compensatory shock following a major abdominal surgery.
Recognizing subtle shifts in vital signs is essential for early identification of postoperative hemorrhage.
2
Evaluate the newly resulted laboratory value.
A hemoglobin level of 7.37.3 g/dL is critically low and corroborates the vital sign trends, pointing toward active bleeding.
Correlating clinical presentation with diagnostic data confirms the severity of the client's condition.
3
Determine the appropriate nursing intervention within the LPN/LVN scope of practice.
The nurse must escalate the findings to the registered nurse or healthcare provider immediately.
Practical nurses must recognize complications and escalate care for interventions that fall outside their scope, such as administering blood products or altering the medical plan of care.

The nurse should first perform hand hygiene and don gloves, then cleanse the meatus from front to back. Next, the client should begin voiding to flush the urethra. The nurse then catches the midstream sample and removes the cup before the voiding is complete.
To obtain an uncontaminated midstream clean-catch urine specimen, the nurse must follow a strict procedural sequence: apply personal protective equipment, cleanse the meatus from front to back, allow the initial stream to flush the urethra, collect the midstream sample, and remove the cup before the client finishes voiding. This ensures the laboratory results reflect the actual bladder contents rather than external flora.

Step-by-Step Solution

1
Perform hand hygiene and apply clean exam gloves.
The nurse is prepared to assist the client using standard precautions.
Prevents the introduction of the nurse's flora to the client and protects the nurse from exposure to body fluids.
2
Cleanse the urethral meatus using antiseptic wipes in a front-to-back motion.
The external genitalia are cleansed of surface bacteria.
Front-to-back cleansing prevents the introduction of gastrointestinal pathogens into the urinary tract and specimen.
3
Direct the client to begin voiding a small amount of urine into the toilet or bedpan.
The distal urethra is flushed with the initial flow of urine.
The initial stream clears microorganisms that naturally colonize the urethral opening.
4
Position the sterile collection cup into the active stream of urine.
The midstream urine is collected in the sterile container.
Midstream urine provides the most accurate reflection of bladder contents for laboratory testing.
5
Remove the specimen container from the stream before the client completely finishes voiding.
The collection is completed without contamination from the end of the urinary stream.
The final drops of urine can pick up skin flora from the external genitalia, potentially skewing the test results.

Key Concept

The purpose of a midstream clean-catch urine specimen is to obtain a sample that is free of external contamination. Proper sequencing ensures that external flora and urethral contaminants are cleared before the actual sample is collected into the sterile container.

During a shift at a community health clinic, a practical nurse evaluates clients presenting for scheduled immunizations. Which clients can safely undergo their prescribed vaccination therapies today? (Select all that apply)

Select all that apply

Show answer & explanation

Answer: A pediatric client with a low-grade fever and clear nasal discharge scheduled for the measles, mumps, and rubella (MMR) vaccine.; An adolescent client who experienced mild injection site erythema after a previous dose, scheduled for a Tdap booster.

Answer

The clients who can safely receive their vaccines are the child with a mild respiratory illness and the adolescent with a history of a mild localized injection reaction.
Mild acute illnesses, such as an upper respiratory infection with a low-grade fever, do not necessitate withholding vaccines like the MMR. Similarly, a mild localized reaction (erythema or soreness) to a previous vaccine dose is a normal expected finding and is not a contraindication for receiving subsequent boosters like the Tdap.

Step-by-Step Solution

1
Evaluate each client's current health status and medical history against the type of vaccine ordered (live-attenuated versus inactivated).
Identified which clients have conditions that interact negatively with the specific vaccine components.
Different vaccine formulations carry distinct risks; live vaccines require an intact immune system and are generally avoided during pregnancy.
2
Differentiate between true contraindications and general precautions or expected side effects.
Determined that a mild cold (low-grade fever) and prior localized erythema are not reasons to withhold immunization.
Delaying vaccines for minor illnesses creates missed opportunities for critical disease prevention.
3
Identify absolute contraindications for the specific vaccines listed in the scenario.
Recognized that pregnancy, severe immunosuppression from corticosteroids, and a history of intussusception are major safety risks.
Administering live vaccines to immunocompromised or pregnant clients, or the rotavirus vaccine to an infant with a history of bowel telescoping, can cause severe harm.

An older adult client diagnosed with heart failure is prescribed a daily scheduled dose of oral spironolactone. During the morning chart review, the practical nurse notes that the client's most recent serum potassium level is 5.8 mEq/L5.8 \text{ mEq/L}. Which action should the practical nurse take next?

Show answer & explanation

Answer: Withhold the spironolactone and promptly report the potassium level to the registered nurse.

Answer

Withhold the spironolactone and promptly report the potassium level to the registered nurse.
Spironolactone is a potassium-sparing diuretic that can cause or worsen hyperkalemia. A serum potassium level of 5.8 mEq/L5.8 \text{ mEq/L} is elevated above the normal expected range. Administering the medication under these conditions could lead to severe cardiac dysrhythmias. The practical nurse must withhold the medication and immediately notify the registered nurse or healthcare provider to ensure patient safety.

Step-by-Step Solution

1
Analyze the client's laboratory result.
The serum potassium level is 5.8 mEq/L5.8 \text{ mEq/L}, which indicates hyperkalemia (normal range is typically 3.53.5 to 5.0 mEq/L5.0 \text{ mEq/L}).
Recognizing abnormal laboratory values is essential before medication administration.
2
Identify the mechanism of the prescribed medication.
Spironolactone is a potassium-sparing diuretic.
Understanding the drug class helps predict how it will affect the client's current physiological state.
3
Determine the risk of administration.
Giving a potassium-sparing drug to a hyperkalemic client will dangerously increase potassium levels, risking fatal cardiac dysrhythmias.
Client safety is the primary priority when deciding whether to administer or withhold a drug.
4
Select the appropriate nursing intervention.
The practical nurse must withhold the dose and escalate the finding to the registered nurse.
This action remains within the practical nurse's scope of practice while preventing immediate harm to the client.

During a shift on a surgical unit, a practical nurse is evaluating a client who underwent a partial nephrectomy 4 hours4\text{ hours} ago. The client's current vital signs include a heart rate of 116 beats/min116\text{ beats/min} and a blood pressure of 94/58 mm Hg94/58\text{ mm Hg}. The electronic health record displays a recent postoperative serum hemoglobin level of 11.0 g/dL11.0\text{ g/dL}. The client is awake and reporting moderate incisional pain. Which action should the practical nurse take first?

Show answer & explanation

Answer: Notify the registered nurse immediately regarding the client's current vital signs.

Answer

The practical nurse must immediately notify the registered nurse about the abnormal vital signs.
The correct action prioritizes airway, breathing, and circulation (ABC) principles. Tachycardia combined with borderline hypotension in a client recovering from a highly vascular surgery (partial nephrectomy) strongly suggests acute hemorrhage and early hypovolemic shock. The practical nurse must recognize this life-threatening risk potential and immediately escalate the findings to the registered nurse for rapid intervention.

Step-by-Step Solution

1
Analyze the client's vital signs in the context of the postoperative timeline.
The heart rate of 116 beats/min116\text{ beats/min} and blood pressure of 94/58 mm Hg94/58\text{ mm Hg} represent a significant deviation from expected stability for a client 4 hours4\text{ hours} post-nephrectomy.
Identifying subtle deviations in baseline vital signs is the first step in recognizing physiological instability.
2
Evaluate the laboratory data and client symptoms.
The hemoglobin is mildly low (11.0 g/dL11.0\text{ g/dL}) but anticipated after surgery, and moderate pain is a normal postoperative finding.
Differentiating between expected postoperative findings and emergent complications prevents incorrect prioritization.
3
Correlate the abnormal vital signs with surgical risk factors.
The unexplained tachycardia and borderline hypotension point to early hypovolemic shock, strongly suggesting hemorrhage at the highly vascular kidney surgical site.
Understanding the physiological implications of specific procedures helps anticipate severe complications.
4
Determine the safest priority action within the practical nursing scope of practice.
The nurse must escalate this critical change in condition to the registered nurse for advanced assessment and collaborative intervention.
Timely communication of a deteriorating client status is essential to reduce the risk of adverse physiological outcomes.
