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. In a capillary glucose measurement, a client is to receive 10 units of regular insulin and isophane insulin. How should the nurse prepare?

• A. Withdraw ten units of regular insulin from a vial
• B. Withhold the dose until regular insulin is available
• C. Obtain a new vial of regular insulin and withhold
• D. Pull up 30 units from a vial but only administer 10 units

Correct answer: B

Rationale: In insulin administration, regular insulin is typically administered before isophane insulin to manage blood glucose effectively. If regular insulin is not available, it is best to withhold the dose until it can be administered as prescribed. Choice A is incorrect as it suggests withdrawing from a specific vial without specifying regular insulin. Choice C is incorrect as obtaining a new vial of regular insulin may not be necessary if it becomes available shortly. Choice D is incorrect as administering 10 units from a mixture of regular and isophane insulin is not the correct approach.

3. A client with a diagnosis of generalized anxiety disorder is prescribed hydroxyzine. The nurse should instruct the client that this medication may have which potential side effect?

• A. Drowsiness
• B. Dry mouth
• C. Nausea
• D. Headache

Correct answer: A

Rationale: The correct answer is A: Drowsiness. Hydroxyzine is known to cause drowsiness, so clients should be advised to avoid activities like driving until they understand how the medication affects them. Choices B, C, and D are incorrect because dry mouth, nausea, and headache are not commonly associated with hydroxyzine use. It is crucial for the client to be aware of the potential drowsiness to ensure their safety and well-being while taking this medication.

4. The healthcare provider is assessing the effectiveness of the drug amiodarone. Which client statement best indicates that the drug has been effective?

• A. I have not had as many spells of angina.
• B. I have not had as much swelling in my ankles lately.
• C. My doctor told me my cholesterol levels were improving with each visit.
• D. I do not notice as many irregular heartbeats as before I started taking this medication.

Correct answer: D

Rationale: The correct answer is option D. The effectiveness of amiodarone is best assessed by a reduction in irregular heartbeats since it is primarily used to treat ventricular dysrhythmias. This drug's main purpose is to control irregular heart rhythms, so a decrease in irregular heartbeats indicates its effectiveness. Options A, B, and C are incorrect because amiodarone is not primarily used to address angina, ankle swelling, or cholesterol levels, so improvements in these areas do not directly reflect the drug's effectiveness.

5. A client with chronic kidney disease is prescribed lanthanum carbonate. The nurse should monitor for which potential side effect?

• A. Hypercalcemia
• B. Hypocalcemia
• C. Hyperkalemia
• D. Hypokalemia

Correct answer: A

Rationale: Lanthanum carbonate is prescribed in chronic kidney disease to bind dietary phosphorus in the gastrointestinal tract. This action can lead to decreased phosphorus absorption and potential hypercalcemia due to the increased serum calcium levels. Therefore, the nurse should monitor the client for signs and symptoms of hypercalcemia, such as confusion, fatigue, and muscle weakness. Choices B, C, and D are incorrect as lanthanum carbonate's mechanism of action does not lead to hypocalcemia, hyperkalemia, or hypokalemia.
