Nursing Elites

1. A nurse in an emergency department is assessing a client who reports ingesting thirty diazepam tablets. After securing the client's airway and initiating an IV, which of the following actions should the nurse do next?

• A. Monitor the client's IV site for thrombophlebitis.
• B. Administer flumazenil to the client.
• C. Evaluate the client for further suicidal behavior.
• D. Initiate seizure precautions for the client.

Correct answer: B

Rationale: Administering flumazenil is the priority to reverse the effects of diazepam overdose. Flumazenil is a specific benzodiazepine receptor antagonist that can rapidly reverse the sedative effects of diazepam. Monitoring the IV site for thrombophlebitis is important but not the immediate priority in this situation. Evaluating the client for further suicidal behavior is important for comprehensive care but is not the most urgent action at this moment. Initiating seizure precautions may be necessary, but the priority is to counteract the sedative effects of diazepam with flumazenil.

2. Which lab value is critical for monitoring warfarin therapy?

• A. Monitor INR
• B. Monitor platelet count
• C. Monitor sodium levels
• D. Monitor calcium levels

Correct answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial for monitoring warfarin therapy as it helps assess the therapeutic effectiveness and bleeding risks associated with the medication. INR measures the clotting tendency of blood, which is essential in determining the appropriate dosage of warfarin. Monitoring platelet count (B), sodium levels (C), or calcium levels (D) is not primarily used for assessing warfarin therapy. Platelet count is more relevant in assessing bleeding disorders, while sodium and calcium levels are typically monitored for different medical conditions unrelated to warfarin therapy.

3. A nurse is caring for a client who is receiving continuous cardiac monitoring. The client's heart rate is 69/min, and the PR interval is 0.24 seconds. What cardiac rhythm should the nurse interpret this finding as?

• A. First-degree AV block.
• B. Premature ventricular contraction.
• C. Sinus bradycardia.
• D. Atrial fibrillation.

Correct answer: A

Rationale: The correct answer is A: First-degree AV block. A PR interval of 0.24 seconds indicates a prolonged PR interval, which is characteristic of first-degree AV block. This rhythm is considered benign and often does not require treatment. Choice B, premature ventricular contraction, is characterized by early, abnormal ventricular contractions and would not be indicated by the findings provided. Choice C, sinus bradycardia, would present with a normal PR interval but a heart rate less than 60 beats per minute. Choice D, atrial fibrillation, is characterized by an irregularly irregular rhythm with no identifiable P waves, which does not align with the findings of a prolonged PR interval in this scenario.

4. 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.

5. A nurse is planning care for a client who is postoperative following abdominal surgery. Which of the following interventions should the nurse implement to prevent respiratory complications?

• A. Encourage the client to ambulate twice daily.
• B. Encourage the client to deep breathe and cough every hour.
• C. Encourage the client to use an incentive spirometer every hour.
• D. Instruct the client to avoid coughing to prevent pain.

Correct answer: C

Rationale: The correct answer is C. Encouraging the client to use an incentive spirometer every hour is crucial to prevent respiratory complications postoperatively. Incentive spirometry helps in lung expansion and prevents atelectasis, which is common after abdominal surgery. Choice A, encouraging ambulation, is important for preventing complications but does not directly address respiratory issues. Choice B, deep breathing and coughing every hour, is also beneficial but not as effective in preventing atelectasis as using an incentive spirometer. Choice D, instructing the client to avoid coughing, is incorrect as coughing helps clear secretions and prevent respiratory complications.
