Nursing Elites

1. What is the most important nursing intervention for a patient with a suspected pulmonary embolism?

• A. Administer anticoagulants
• B. Administer oxygen
• C. Reposition the patient
• D. Monitor oxygen saturation

Correct answer: A

Rationale: The most important nursing intervention for a patient with a suspected pulmonary embolism is to administer anticoagulants. Anticoagulants help prevent further clot formation in the patient's blood vessels, reducing the risk of complications such as worsening of the pulmonary embolism or development of new clots. Administering oxygen (Choice B) may be necessary to support the patient's oxygenation, but anticoagulants take precedence as they target the underlying cause of the pulmonary embolism. Repositioning the patient (Choice C) and monitoring oxygen saturation (Choice D) are important aspects of patient care but are not the primary intervention for a suspected pulmonary embolism.

2. Which electrolyte imbalance is most concerning in a patient taking digoxin?

• A. Monitor potassium levels
• B. Monitor calcium levels
• C. Monitor sodium levels
• D. Monitor magnesium levels

Correct answer: A

Rationale: The correct answer is to monitor potassium levels. Patients taking digoxin are at risk of developing toxicity due to hypokalemia. Low potassium levels can potentiate the toxic effects of digoxin on the heart, leading to serious arrhythmias. Monitoring calcium levels (Choice B) is not the primary concern in patients taking digoxin. While calcium levels play a role in cardiac function, hypocalcemia is not directly associated with digoxin toxicity. Monitoring sodium levels (Choice C) is important for other conditions but is not the primary concern in a patient taking digoxin. Monitoring magnesium levels (Choice D) is also essential, but hypomagnesemia is not as directly linked to digoxin toxicity as hypokalemia.

3. A nurse is caring for a client who is receiving a continuous heparin infusion. Which of the following laboratory values should the nurse monitor to evaluate the effectiveness of the therapy?

• A. Serum potassium
• B. Platelets
• C. aPTT
• D. INR

Correct answer: C

Rationale: The correct answer is C: aPTT. Monitoring the activated partial thromboplastin time (aPTT) is crucial when a client is receiving heparin therapy. The aPTT reflects the clotting time and helps assess the effectiveness of heparin in preventing clot formation. Keeping the aPTT within the therapeutic range ensures that the medication is working optimally. Choices A, B, and D are incorrect because serum potassium, platelets, and INR are not direct indicators of heparin's effectiveness or therapeutic range.

4. A nurse is reviewing the laboratory report of a client who has been taking lithium carbonate for the past 12 months. The nurse notes a lithium level of 0.8 mEq/L. Which of the following orders from the provider should the nurse expect?

• A. Withhold the next dose
• B. Increase the dosage
• C. Discontinue the medication
• D. Administer the medication

Correct answer: D

Rationale: The correct answer is to administer the medication (Choice D) since the lithium level of 0.8 mEq/L falls within the therapeutic range of 0.6-1.2 mEq/L. Withholding the next dose (Choice A) or increasing the dosage (Choice B) is not necessary as the current level is appropriate. Discontinuing the medication (Choice C) is not warranted based on the given lithium level. It is crucial to maintain therapeutic levels to ensure the medication's effectiveness without causing toxicity.

5. A client is postoperative following a total knee arthroplasty. Which of the following instructions should the nurse include in the discharge teaching?

• A. Cross your legs when sitting to prevent discomfort.
• B. Perform range-of-motion exercises every 4 hours.
• C. Wear compression stockings daily.
• D. Apply heat to the incision site daily.

Correct answer: C

Rationale: The correct answer is C: 'Wear compression stockings daily.' Wearing compression stockings is essential after knee surgery to prevent venous stasis and reduce the risk of blood clots. Choice A is incorrect as crossing legs when sitting can increase the risk of blood clots. Choice B is incorrect because performing range-of-motion exercises every 4 hours may not be suitable for all clients post total knee arthroplasty. Choice D is incorrect as applying heat to the incision site can increase the risk of infection.
