Nursing Elites

1. 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.

2. A client who received a kidney transplant is taking azathioprine (Imuran), and the nurse provides instructions about the medication. Which statement by the client indicates a need for further instructions?

• A. I need to watch for signs of infection.
• B. I need to discontinue the medication after 14 days of use.
• C. I can take the medication with meals to minimize nausea.
• D. I need to call the health care provider (HCP) if more than one dose is missed.

Correct answer: B

Rationale: Azathioprine is an immunosuppressant taken for life. Discontinuing the medication after 14 days is incorrect.

3. A client is being taught about the use of enoxaparin (Lovenox) for the prevention of deep vein thrombosis. Which instruction should the nurse include in the teaching plan?

• A. Inject the medication subcutaneously.
• B. Avoid massaging the injection site after administration.
• C. Administer the medication at the same time each day.
• D. Do not expel the air bubble from the syringe before injection.

Correct answer: C

Rationale: Enoxaparin (Lovenox) is administered subcutaneously at the same time each day to maintain consistent blood levels. Injecting the medication into the muscle is incorrect, as it should be given subcutaneously. Massaging the injection site should be avoided to prevent bruising. The air bubble in the prefilled syringe should not be expelled, as it ensures the full dose is administered.

4. 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.

5. A client who is receiving digoxin (Lanoxin) daily has a serum potassium level of 3.0 mEq/L and is complaining of anorexia. A healthcare provider prescribes a digoxin level to rule out digoxin toxicity. A nurse checks the results, knowing that which of the following is the therapeutic serum level (range) for digoxin?

• A. 3 to 5 ng/mL
• B. 0.5 to 2 ng/mL
• C. 1.2 to 2.8 ng/mL
• D. 3.5 to 5.5 ng/mL

Correct answer: B

Rationale: The therapeutic serum level for digoxin ranges from 0.5 to 2 ng/mL. This range is considered optimal for therapeutic effects while minimizing the risk of toxicity. Levels above 2 ng/mL may lead to digoxin toxicity, which can manifest as anorexia among other symptoms. Therefore, the nurse should be vigilant in monitoring the digoxin levels to ensure the client's safety and therapeutic effectiveness of the medication.
