1. A client has a fungal infection and a new prescription for amphotericin B. Which of the following laboratory values should the nurse report to the provider before initiating the medication?
- A. Sodium 140 mEq/L
- B. Potassium 4.5 mEq/L
- C. BUN 55 mg/dL
- D. Glucose 120 mg/dL
Correct answer: C
Rationale: An elevated BUN level of 55 mg/dL should be reported before starting amphotericin B due to its nephrotoxic effects. Amphotericin B can cause kidney damage, and an elevated BUN indicates impaired kidney function, increasing the risk of further renal damage with this medication. Sodium, potassium, and glucose levels are not directly associated with the nephrotoxic effects of amphotericin B, making choices A, B, and D incorrect.
2. A client has a new prescription for Furosemide. Which of the following instructions should be included by the nurse?
- A. Take this medication at bedtime.
- B. Avoid eating foods high in potassium.
- C. Change positions slowly.
- D. Take this medication with meals.
Correct answer: C
Rationale: The correct instruction to include when a client is prescribed Furosemide is to change positions slowly. Furosemide is a diuretic that can lead to orthostatic hypotension, causing dizziness and increasing the risk of falls. By advising the client to change positions slowly, the nurse helps prevent these potential adverse effects.
3. When teaching a client with a new prescription for Lithium, which instruction should the nurse include?
- A. Restrict fluid intake to 1,000 mL per day.
- B. Maintain a consistent sodium intake.
- C. Take the medication at bedtime.
- D. Expect to have frequent headaches.
Correct answer: B
Rationale: Maintaining a consistent sodium intake is crucial when taking Lithium to help regulate lithium levels in the body and prevent toxicity. Sodium levels can impact the effectiveness and safety of Lithium therapy. Restricting fluid intake to 1,000 mL per day (Choice A) is not appropriate and could lead to dehydration. Taking the medication at bedtime (Choice C) may vary depending on the individual's schedule but is not a critical instruction. Expecting to have frequent headaches (Choice D) is not a common side effect of Lithium.
4. A client has a new prescription for radioactive iodine to treat Hyperthyroidism. Which of the following instructions should the nurse include?
- A. Expect a metallic taste in the mouth.
- B. Avoid contact with pregnant women for 1 week.
- C. Administer iodine solution using a straw.
- D. Take thyroid replacement medication for 3 weeks after treatment.
Correct answer: B
Rationale: When a client undergoes radioactive iodine treatment for hyperthyroidism, they can emit radiation for a short time. To prevent radiation exposure to others, especially pregnant women, infants, and small children, clients should avoid close contact for about 1 week following therapy. This precaution is essential to protect vulnerable individuals from potential harm. Choice A is incorrect because a metallic taste in the mouth is not a common side effect of radioactive iodine treatment. Choice C is incorrect because administering iodine solution using a straw is not a standard practice in this treatment. Choice D is incorrect because taking thyroid replacement medication for 3 weeks after treatment is not a typical instruction associated with radioactive iodine therapy for hyperthyroidism.
5. A client with angina asks about obtaining a prescription for sildenafil to treat erectile dysfunction. Which of the following medications is contraindicated with Sildenafil?
- A. Aspirin
- B. Isosorbide
- C. Clopidogrel
- D. Atorvastatin
Correct answer: B
Rationale: Isosorbide is an organic nitrate used to manage angina. Concurrent use of sildenafil with organic nitrates, like isosorbide, is contraindicated due to the risk of fatal hypotension. It is essential for clients to avoid taking nitrate medications within 24 hours of using isosorbide to prevent serious complications.
