The healthcare provider is analyzing the laboratory results of a client with leukemia who has received a regimen of chemotherapy. Which laboratory value would the healthcare provider specifically note as a result of the massive cell destruction that occurred from the chemotherapy?

Correct Answer: C

Rationale: Following chemotherapy for leukemias and lymphomas, hyperuricemia is common due to the massive cell kill. Chemotherapy leads to the rapid destruction of cancer cells, releasing large amounts of nucleic acids, which are broken down into uric acid. Monitoring and managing uric acid levels are crucial to prevent complications such as renal damage and gout.

Correct Answer: C

Rationale: The correct time for a client to take a daily dose of prednisone is early morning. Corticosteroids like prednisone should be taken in the morning to mimic the body's natural hormone release pattern. This timing helps reduce the risk of disrupting the body's internal clock and minimizes the potential for insomnia or other sleep disturbances.

Correct Answer: A

Rationale: In this scenario, the correct answer is A) At bedtime. Ranitidine is a histamine-2 blocker commonly prescribed for conditions like gastroesophageal reflux disease (GERD) and peptic ulcers. The optimal time for administering ranitidine is at bedtime because it helps in reducing nocturnal acid secretion and provides the best acid suppression during the night when gastric acid production is at its peak. Option B) After lunch is incorrect because the timing does not coincide with the physiological need for acid suppression, which is more crucial during the night. Option C) With supper is incorrect as well because taking ranitidine with supper may not provide adequate acid suppression during the night when it is most needed. Option D) Before breakfast is also incorrect as it does not align with the goal of reducing nocturnal acid secretion, which is the primary purpose of prescribing ranitidine. Educationally, understanding the rationale behind the timing of medication administration is crucial for providing optimal patient care. It is essential for nurses to comprehend the pharmacokinetics and pharmacodynamics of medications to ensure their therapeutic effectiveness. By grasping the appropriate timing of administration for drugs like ranitidine, nurses can contribute to improved patient outcomes and medication efficacy.

Correct Answer: B

Rationale: The correct answer is B) Coffee, cola, and chocolate. Theophylline is a xanthine derivative bronchodilator used to treat respiratory conditions like asthma and chronic obstructive pulmonary disease (COPD). Xanthines can interact with caffeine found in coffee, cola, and chocolate, leading to increased side effects like palpitations, tremors, and insomnia. Limiting intake of these caffeinated products helps prevent excessive stimulation of the central nervous system. Options A, C, and D are incorrect because they do not have a direct interaction with theophylline. Oranges, pineapple, oysters, lobster, shrimp, cottage cheese, cream cheese, and dairy creamers do not contain substances that significantly interfere with the metabolism or action of theophylline. It is crucial for healthcare providers and patients to be aware of potential drug-food interactions to ensure optimal therapeutic outcomes and prevent adverse effects. In an educational context, understanding drug-food interactions is essential for safe medication administration. Educating patients on dietary restrictions while taking specific medications can help them achieve the desired treatment effects and avoid potential complications. Nurses play a vital role in patient education regarding medication management, including dietary considerations, to promote medication adherence and patient safety.

Correct Answer: C

Rationale: The correct answer is C. Double vision, loss of appetite, and nausea are classic signs of digoxin toxicity. Other signs may include bradycardia, visual disturbances, and confusion. These symptoms are indicators that the client may be experiencing adverse effects due to elevated levels of digoxin in the system, requiring immediate medical attention to prevent serious complications.
