Nursing Elites

1. Insulin glargine (Lantus) is prescribed for a client with diabetes mellitus. The nurse tells the client that it is best to take the insulin:

• A. 1 hour after each meal
• B. Once daily, at the same time each day
• C. 15 minutes before breakfast, lunch, and dinner
• D. Before each meal, based on the blood glucose level

Correct answer: B

Rationale: Insulin glargine (Lantus) is a long-acting insulin with a duration of action of approximately 24 hours, making it suitable for once-daily dosing at the same time each day. This regimen helps maintain consistent blood glucose levels and simplifies the client's treatment routine. Taking insulin glargine once daily provides basal insulin coverage throughout the day, reducing the risk of hypoglycemia compared to short-acting insulins that are taken before each meal.

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 receiving nitrofurantoin (Macrodantin) calls the health care provider's office complaining of side effects related to the medication. Which side effect indicates the need to stop treatment with this medication?

• A. Nausea
• B. Diarrhea
• C. Anorexia
• D. Cough and chest pain

Correct answer: D

Rationale: Pulmonary reactions such as cough and chest pain are serious side effects associated with nitrofurantoin that require immediate discontinuation of the medication to prevent potential severe respiratory complications.

4. A client is receiving morphine sulfate for pain management. Which assessment finding requires immediate action?

• A. Constipation
• B. Drowsiness
• C. Respiratory rate of 10 breaths per minute
• D. Nausea

Correct answer: C

Rationale: A respiratory rate of 10 breaths per minute indicates respiratory depression, a serious side effect of morphine sulfate that can lead to respiratory compromise and requires immediate intervention. Constipation, drowsiness, and nausea are common side effects of morphine but are not immediately life-threatening compared to respiratory depression. Monitoring and addressing a low respiratory rate are crucial in preventing further respiratory distress or failure.

5. A clinic nurse prepares to administer an MMR (measles, mumps, rubella) vaccine to a child. How is this vaccine best administered?

• A. Intramuscularly in the deltoid muscle
• B. Subcutaneously in the gluteal muscle
• C. Subcutaneously in the outer aspect of the upper arm
• D. Intramuscularly in the anterolateral aspect of the thigh

Correct answer: C

Rationale: The MMR vaccine is best administered subcutaneously in the outer aspect of the upper arm. This route allows for proper absorption and efficacy of the vaccine while minimizing the risk of injury or discomfort to the child.
