Nursing Elites

1. A 6-month-old infant is prescribed digoxin for the treatment of congestive heart failure. Which observation by the practical nurse (PN) warrants immediate intervention for signs of digoxin toxicity?

• A. Apical heart rate of 60 beats/min
• B. Sweating across the forehead
• C. Poor sucking effort
• D. Respiratory rate of 30 breaths/min

Correct answer: A

Rationale: A heart rate of 60 beats/min for a 6-month-old infant warrants immediate intervention as it falls below the normal range. The normal heart rate for a 6-month-old is 80 to 150 beats/min when awake, and a rate of 70 beats/min while sleeping is considered within normal limits. Bradycardia (heart rate <60 beats/min) in infants can be a sign of digoxin toxicity, necessitating prompt evaluation and intervention to prevent adverse effects. Sweating across the forehead (Choice B) is a non-specific symptom and may not directly indicate digoxin toxicity. Poor sucking effort (Choice C) and a respiratory rate of 30 breaths/min (Choice D) are not typically associated with digoxin toxicity and do not require immediate intervention in the context of this question.

2. A client with hypertension is prescribed metoprolol. The healthcare provider should monitor the client for which potential side effect?

• A. Bradycardia
• B. Tachycardia
• C. Hyperglycemia
• D. Hyponatremia

Correct answer: A

Rationale: Metoprolol is a beta-blocker that works by slowing the heart rate and reducing blood pressure. One of the potential side effects of metoprolol is bradycardia, which is a slow heart rate. Monitoring for bradycardia is crucial as it can be an adverse effect of this medication.

3. A client with hypertension is prescribed doxazosin. The nurse should monitor for which potential side effect?

• A. Hypotension
• B. Hypertension
• C. Hyperglycemia
• D. Hypernatremia

Correct answer: A

Rationale: The correct answer is A: Hypotension. Doxazosin is an alpha-blocker medication commonly used to treat hypertension. One of the potential side effects of doxazosin is causing a sudden drop in blood pressure, leading to hypotension. Therefore, the nurse should closely monitor the client for signs and symptoms of low blood pressure when initiating or adjusting the dose of doxazosin.

4. The client is receiving vancomycin, and the nurse plans to draw blood for a peak and trough to determine... the best timing for these levels?

• A. Midway through administration of the IV dose and 30 minutes before the next
• B. Two hours after completion of the IV dose and 30 minutes before the next
• C. Two hours after completion of the IV dose and one hour before the next
• D. Immediately after completion of the IV dose and 30 minutes before

Correct answer: B

Rationale: To accurately determine peak and trough levels of vancomycin, blood should be drawn two hours after the completion of the IV dose and 30 minutes before the next dose. This timing allows for appropriate assessment of the drug levels in the body, ensuring accurate monitoring of therapeutic and toxic concentrations. Choice A is incorrect as drawing blood midway through administration does not provide an accurate peak level. Choice C is incorrect as drawing blood one hour before the next dose does not represent the trough level. Choice D is incorrect because drawing blood immediately after completion of the IV dose does not allow enough time for the drug to reach peak levels.

5. A client with a history of heart failure is prescribed carvedilol. The nurse should monitor for which potential side effect?

• A. Bradycardia
• B. Tachycardia
• C. Hypertension
• D. Hyperglycemia

Correct answer: A

Rationale: When a client is prescribed carvedilol, the nurse should monitor for bradycardia, a potential side effect of this medication. Carvedilol is a beta-blocker that can slow down the heart rate, so monitoring for signs of bradycardia is essential to prevent any adverse effects on the client's cardiovascular system. Tachycardia (Choice B) is less likely to occur with carvedilol since it primarily works to reduce heart rate. Hypertension (Choice C) and hyperglycemia (Choice D) are not common side effects associated with carvedilol.
