Nursing Elites

1. The healthcare provider prescribes exenatide (Byetta) for a client with type 1 diabetes mellitus who takes insulin. What is the appropriate intervention for the nurse?

• A. Administer the medication within 60 minutes before the morning and evening meal.
• B. Withhold the medication and question the prescription with the healthcare provider.
• C. Monitor the client for gastrointestinal side effects after administration of the medication.
• D. Withdraw the insulin from the Penlet into an insulin syringe to prepare for administration.

Correct answer: B

Rationale: Exenatide (Byetta) is specifically indicated for the treatment of type 2 diabetes mellitus and is not recommended for clients with type 1 diabetes mellitus who are taking insulin. Choice A is incorrect because exenatide should not be administered to a client with type 1 diabetes mellitus who takes insulin. Choice C is not the most appropriate initial action when the prescription is not suitable for the client. Choice D is unrelated to the administration of exenatide. Therefore, the appropriate intervention for the nurse is to withhold the medication and question the prescription with the healthcare provider to ensure the safety and appropriateness of the treatment plan for the client.

2. 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.

3. A client is taking levothyroxine (Synthroid) for hypothyroidism. Which symptom would indicate to the nurse that the client is taking too much medication?

• A. Bradycardia
• B. Lethargy
• C. Tremors
• D. Constipation

Correct answer: C

Rationale: When a client is taking an excessive dose of levothyroxine (Synthroid), it can lead to symptoms of hyperthyroidism. Tremors are a common sign of excessive medication, along with tachycardia and insomnia. Bradycardia, lethargy, and constipation are typical symptoms of hypothyroidism, indicating that the client may require a higher dose of levothyroxine rather than too much.

4. A client is prescribed calcium gluconate after thyroidectomy. The medication is most likely prescribed to:

• A. Treat thyroid storm.
• B. Prevent cardiac irritability.
• C. Treat hypocalcemic tetany.
• D. Stimulate the release of parathyroid hormone.

Correct answer: C

Rationale: After a thyroidectomy, the parathyroid glands can be inadvertently removed or damaged, leading to a decrease in calcium levels and potentially causing hypocalcemic tetany. Calcium gluconate is given to supplement calcium levels and prevent or treat hypocalcemia-related symptoms, such as muscle spasms and tetany.

5. 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.
