Nursing Elites

1. Sildenafil (Viagra) is prescribed to treat a client with erectile dysfunction. A nurse reviews the client's medical record and would question the prescription if which of the following is noted in the client's history?

• A. Neuralgia
• B. Insomnia
• C. Use of nitroglycerin
• D. Use of multivitamins

Correct answer: C

Rationale: The correct answer is C. Sildenafil (Viagra) enhances the vasodilating effect of nitric oxide and is contraindicated with the concurrent use of organic nitrates and nitroglycerin. Using nitroglycerin together with Viagra can lead to severe hypotension and cardiovascular collapse, making it unsafe to combine both medications.

2. A client is receiving instructions from a healthcare provider about intranasal desmopressin acetate (DDAVP). The healthcare provider explains that which of the following is a side effect of the medication?

• A. Headache
• B. Vulval pain
• C. Runny nose
• D. Flushed skin

Correct answer: C

Rationale: Intranasal desmopressin can cause a runny or stuffy nose as a side effect due to its mode of administration through the nasal passages.

3. A client with portosystemic encephalopathy is receiving oral lactulose (Chronulac) daily. The nurse assesses which of the following to determine medication effectiveness?

• A. Lung sounds
• B. Blood pressure
• C. Blood ammonia level
• D. Serum potassium level

Correct answer: C

Rationale: In portosystemic encephalopathy, the liver's ability to detoxify ammonia is impaired, leading to elevated blood ammonia levels, which can cause neurological symptoms such as encephalopathy. Lactulose is given to reduce ammonia levels by promoting its excretion through the bowel. Therefore, assessing the blood ammonia level is crucial to determine the effectiveness of lactulose therapy in managing portosystemic encephalopathy.

4. A client with severe acne is seen in the clinic, and the healthcare provider prescribes isotretinoin. The nurse reviews the client's medication record and would contact the healthcare provider if the client is taking which medication?

• A. Vitamin A
• B. Digoxin (Lanoxin)
• C. Furosemide (Lasix)
• D. Phenytoin (Dilantin)

Correct answer: A

Rationale: Isotretinoin is a metabolite of vitamin A, which can lead to toxicity when taken together. Therefore, it is crucial to avoid concurrent use of vitamin A supplements with isotretinoin. Contacting the healthcare provider to discuss discontinuing vitamin A supplements is important to prevent potential adverse effects. Choices B, C, and D are incorrect as they are not known to interact significantly with isotretinoin.

5. A client with hyperlipidemia is prescribed atorvastatin (Lipitor). Which instruction should the nurse include in the teaching plan?

• A. Take the medication in the morning.
• B. Avoid consuming grapefruit juice.
• C. Increase your intake of dairy products.
• D. Take the medication with food.

Correct answer: B

Rationale: The correct instruction for the nurse to include in the teaching plan is to advise the client to avoid consuming grapefruit juice. Grapefruit juice can increase the risk of atorvastatin (Lipitor) toxicity by inhibiting its metabolism. Atorvastatin is typically taken in the evening as cholesterol synthesis occurs at night. Increasing dairy intake is not specifically recommended for atorvastatin therapy, and the medication can be taken with or without food.
