Nursing Elites

1. A healthcare professional is monitoring a client who is receiving intravenous amphotericin B. Which of the following should prompt the healthcare professional to notify the healthcare provider immediately?

• A. Fever
• B. Headache
• C. Nausea
• D. Oliguria

Correct answer: D

Rationale: Amphotericin B is known to cause nephrotoxicity, which can lead to kidney damage. Oliguria, which is decreased urine output, is a concerning sign of kidney dysfunction and should be reported promptly to the healthcare provider to prevent further complications. Fever, headache, and nausea are common side effects of amphotericin B but are not as critical as oliguria in indicating potential kidney damage.

2. A home health care nurse is visiting a client with elevated triglyceride levels and a serum cholesterol level of 398 mg/dL. The client is taking cholestyramine (Questran). Which of the following statements, if made by the client, indicates the need for further education?

• A. Constipation and bloating might be a problem.
• B. I'll continue to watch my diet and reduce my fats.
• C. Walking a mile each day will help the whole process.
• D. I'll continue my nicotinic acid from the health food store.

Correct answer: D

Rationale: Nicotinic acid, even an over-the-counter form, should be avoided because it may lead to liver abnormalities. All lipid-lowering medications also can cause liver abnormalities, so a combination of nicotinic acid and cholestyramine resin is to be avoided. Constipation and bloating are the two most common side effects. Walking and the reduction of fats in the diet are therapeutic measures to reduce cholesterol and triglyceride levels.

3. The client with acute myelocytic leukemia is being treated with busulfan (Myleran). Which laboratory value should the nurse specifically monitor during treatment with this medication?

• A. Clotting time
• B. Uric acid level
• C. Potassium level
• D. Blood glucose level

Correct answer: B

Rationale: The correct answer is B, Uric acid level. Busulfan can cause an increase in uric acid levels, leading to hyperuricemia, renal stones, and acute renal failure. Monitoring uric acid levels is crucial to detect and manage potential complications associated with busulfan therapy.

4. A client who is taking hydrochlorothiazide (HydroDIURIL, HCTZ) has been started on triamterene (Dyrenium) as well. The client asks the nurse why both medications are required. The nurse formulates a response, based on the understanding that:

• A. Both are weak potassium-losing diuretics.
• B. The combination of these medications prevents renal toxicity.
• C. Hydrochlorothiazide is less expensive, so using a combination of diuretics is cost-effective.
• D. Triamterene is a potassium-sparing diuretic, whereas hydrochlorothiazide is a potassium-losing diuretic.

Correct answer: D

Rationale: The combination of triamterene and hydrochlorothiazide is used because triamterene is a potassium-sparing diuretic, which helps retain potassium, while hydrochlorothiazide is a potassium-losing diuretic, which promotes potassium excretion. This combination helps balance potassium levels in the body, preventing imbalances that can occur when using potassium-losing diuretics alone.

5. The camp nurse asks the children preparing to swim in the lake if they have applied sunscreen. The nurse reminds the children that chemical sunscreens are most effective when applied:

• A. Immediately before swimming
• B. 15 minutes before exposure to the sun
• C. Immediately before exposure to the sun
• D. At least 30 minutes before exposure to the sun

Correct answer: D

Rationale: Chemical sunscreens are most effective when applied at least 30 minutes before exposure to the sun to allow them to penetrate the skin and provide optimal protection. Applying sunscreen immediately before swimming (Choice A) or immediately before exposure to the sun (Choice C) may not provide sufficient time for the sunscreen to be absorbed and offer proper protection. Applying sunscreen 15 minutes before sun exposure (Choice B) is also not ideal as it may not allow enough time for the sunscreen to work effectively. Therefore, the correct answer is to apply chemical sunscreen at least 30 minutes before exposure to the sun to ensure it can be absorbed and offer the intended protection. It is important to reapply sunscreen after swimming or sweating to maintain its effectiveness.
