Nursing Elites

1. The client has a PRN prescription for loperamide hydrochloride (Imodium). The nurse understands that this medication is used for which condition?

• A. Constipation
• B. Abdominal pain
• C. An episode of diarrhea
• D. Hematest-positive nasogastric tube drainage

Correct answer: C

Rationale: Loperamide hydrochloride (Imodium) is an antidiarrheal medication commonly used to manage episodes of diarrhea. It works by slowing down gut movement and reducing the frequency of bowel movements. Loperamide is not indicated for constipation, abdominal pain, or hematest-positive nasogastric tube drainage. It is specifically useful in acute and chronic diarrhea, such as in cases of inflammatory bowel disease, to help control symptoms and decrease fluid loss.

2. Tamoxifen is prescribed for the client with metastatic breast carcinoma. The nurse understands that the primary action of this medication is to:

• A. Increase DNA and RNA synthesis.
• B. Promote the biosynthesis of nucleic acids.
• C. Increase estrogen concentration and estrogen response.
• D. Compete with estradiol for binding to estrogen in tissues containing high concentrations of receptors.

Correct answer: D

Rationale: The primary action of tamoxifen, an antineoplastic medication used in metastatic breast carcinoma, is to compete with estradiol for binding to estrogen receptors in tissues with high receptor concentrations. By doing so, tamoxifen reduces DNA synthesis and estrogen response, leading to its therapeutic effect in inhibiting the growth of estrogen-sensitive breast cancer cells.

3. 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.

4. The healthcare provider is applying a topical corticosteroid to a client with eczema. The healthcare provider should monitor for the potential of increased systemic absorption of the medication if the medication were being applied to which of the following body areas?

• A. Back
• B. Axilla
• C. Soles of the feet
• D. Palms of the hands

Correct answer: B

Rationale: The axilla has thinner skin, making it more permeable to topical medications. Areas with thinner skin, like the axilla, allow for higher systemic absorption of topical corticosteroids.

5. A client with a history of chronic heart failure is prescribed spironolactone (Aldactone). Which of the following statements indicates that the client understands the medication teaching?

• A. I will avoid potassium-rich foods.
• B. I will not use a salt substitute.
• C. I will monitor my weight daily.
• D. I will increase my fluid intake as prescribed.

Correct answer: A

Rationale: The correct statement is 'I will avoid potassium-rich foods.' Spironolactone (Aldactone) is a potassium-sparing diuretic, which can lead to hyperkalemia if potassium intake is not regulated. Therefore, avoiding potassium-rich foods is crucial to prevent this complication. Using a salt substitute can also increase potassium levels. Monitoring weight daily is essential in heart failure management, but it is not specific to spironolactone. Increasing fluid intake as prescribed is generally recommended for heart failure management but is not directly related to spironolactone use.
