Nursing Elites

1. A client has been started on long-term therapy with rifampin (Rifadin). A nurse teaches the client that the medication:

• A. Should always be taken with food or antacids
• B. Should be double-dosed if one dose is forgotten
• C. Causes orange discoloration of sweat, tears, urine, and feces
• D. May not be discontinued independently if symptoms are gone in 3 months

Correct answer: C

Rationale: Rifampin causes orange-red discoloration of body secretions, including sweat, tears, urine, and feces. It can also permanently stain soft contact lenses. It is essential to take rifampin exactly as directed and not discontinue it without consulting the healthcare provider.

2. 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.

3. Desmopressin acetate (DDAVP) is prescribed for the treatment of diabetes insipidus. The nurse monitors the client after medication administration for which therapeutic response?

• A. Decreased urinary output
• B. Decreased blood pressure
• C. Decreased peripheral edema
• D. Decreased blood glucose level

Correct answer: A

Rationale: Desmopressin promotes renal conservation of water by increasing the permeability of kidney collecting ducts to water, resulting in decreased urinary output. Therefore, the therapeutic response expected after administering desmopressin for diabetes insipidus is a reduction in urinary output.

4. A client is being taught about the use of nitroglycerin (Nitrostat) for angina. Which statement by the client indicates a need for further teaching?

• A. I will sit or lie down when I take the medication.
• B. I can take up to three tablets, 5 minutes apart, if needed.
• C. I will call 911 if my chest pain is not relieved after taking three tablets.
• D. I will keep the medication in its original dark container.

Correct answer: B

Rationale: The correct administration of nitroglycerin for angina is to take up to three tablets, 5 minutes apart. If the chest pain persists after the third tablet, emergency medical services should be called. Taking more than three tablets or reducing the time interval between doses may lead to hypotension and indicates a need for further teaching.

5. A client with hyperparathyroidism has a serum calcium level of 13 mg/dL. Which medication should be prepared to administer as prescribed to the client?

• A. Calcium chloride
• B. Calcium gluconate
• C. Calcitonin (Miacalcin)
• D. Large doses of vitamin D

Correct answer: C

Rationale: The normal serum calcium level ranges from 8.6 to 10.0 mg/dL. In hypercalcemia, as seen in this client, Calcitonin (Miacalcin) is used to decrease plasma calcium levels by inhibiting bone resorption. Calcium gluconate and calcium chloride are typically used for hypocalcemia, not hypercalcemia. Large doses of vitamin D should be avoided in hypercalcemia as they can exacerbate hypercalcemia by increasing calcium absorption from the intestines.
