1. A client in a coronary care unit is being admitted after CPR post cardiac arrest. The client is receiving IV lidocaine at 2 mg/min. When the client asks the nurse why he is receiving that medication, the nurse should explain that it has which of the following actions?
- A. Prevents dysrhythmias
- B. Slows intestinal motility
- C. Dissolves blood clots
- D. Relieves pain
Correct answer: A
Rationale: Lidocaine is administered to prevent dysrhythmias by delaying conduction in the heart and reducing the automaticity of heart tissue. This action helps stabilize the heart's electrical activity and prevent life-threatening arrhythmias post-cardiac arrest. Choices B, C, and D are incorrect as lidocaine is not used for slowing intestinal motility, dissolving blood clots, or relieving pain in this context.
2. A client has a prescription for Amphotericin B. Which of the following laboratory values should be monitored by the nurse to assess for an adverse effect of this medication?
- A. Serum creatinine.
- B. Serum potassium.
- C. Serum sodium.
- D. Serum calcium.
Correct answer: A
Rationale: Corrected Rationale: Amphotericin B is known to cause nephrotoxicity, a potential adverse effect that can be monitored by checking the client's serum creatinine levels. Regular monitoring of serum creatinine helps in early identification of kidney damage and allows for timely intervention to prevent further complications. Choice B, serum potassium, is not typically associated with adverse effects of Amphotericin B. Choice C, serum sodium, and choice D, serum calcium, are not directly affected by Amphotericin B and are not primary indicators of its adverse effects.
3. A nurse reviewing a client's medical record notes a new prescription for verifying the trough level of the client's medication. Which of the following actions should the nurse take?
- A. Obtain a blood specimen immediately prior to administering the next dose of medication.
- B. Verify that the client has been taking the medication for 24 hours before obtaining a blood specimen.
- C. Ask the client to provide a urine specimen after the next dose of medication.
- D. Administer the medication and obtain a blood specimen 30 minutes later.
Correct answer: A
Rationale: To verify the trough levels of a medication accurately, the nurse should obtain a blood specimen immediately before administering the next dose of the medication. The trough level represents the lowest concentration of the medication in the bloodstream, typically right before the next dose is due. This timing ensures an accurate assessment of the drug's concentration in the body at its lowest point, aiding in determining the drug's effectiveness and potential toxicity levels. Choice B is incorrect because waiting for 24 hours would not provide the trough level. Choice C is incorrect as urine specimens are not used to measure trough levels. Choice D is incorrect as obtaining a blood specimen 30 minutes after administering the medication would not reflect the trough level.
4. A client has a new prescription for Nitrofurantoin. Which of the following instructions should the nurse include?
- A. Take this medication with food.
- B. Avoid dairy products while taking this medication.
- C. Take this medication at bedtime.
- D. Increase your intake of vitamins.
Correct answer: A
Rationale: The correct instruction for a client prescribed Nitrofurantoin is to take the medication with food. Taking Nitrofurantoin with food helps enhance absorption and reduces the risk of gastrointestinal side effects. It is important for the nurse to emphasize this instruction to ensure the client benefits optimally from the medication. Choices B, C, and D are incorrect. Avoiding dairy products is not specifically required with Nitrofurantoin. Taking the medication at bedtime is not a standard instruction. Increasing vitamin intake is not necessary in relation to Nitrofurantoin therapy.
5. A client has a new prescription for Allopurinol. Which of the following instructions should be included by the healthcare provider?
- A. Take this medication at bedtime.
- B. Increase your fluid intake.
- C. Avoid foods high in calcium.
- D. Take this medication with meals.
Correct answer: B
Rationale: Allopurinol can increase the risk of kidney stones as a side effect. To prevent this adverse effect, it is essential for the client to increase their fluid intake. Adequate hydration can help in preventing the formation of kidney stones by keeping urine dilute and flushing out substances that can lead to stone formation.
