1. A patient who is undergoing treatment for cytomegalovirus received his first dose of IV ganciclovir 3 days ago. When reviewing this patient's most recent blood work, what abnormality should the nurse most likely attribute to the use of this drug?
- A. Hemoglobin 17 g/dL (high normal)
- B. INR 3.8 (high)
- C. Platelet count 118,000/mm3 (low)
- D. Leukocytes 11,900/mm3 (high)
Correct answer: C
Rationale: The correct answer is C: Platelet count 118,000/mm3 (low). Ganciclovir, used to treat cytomegalovirus, is known to cause bone marrow suppression, leading to decreased platelet count (thrombocytopenia). This condition can increase the risk of bleeding. Choices A, B, and D are not typically associated with ganciclovir therapy. High hemoglobin levels (choice A) are not commonly seen with ganciclovir treatment. INR elevation (choice B) is associated with coagulation abnormalities, which are not a typical side effect of ganciclovir. Elevated leukocyte count (choice D) is not a common consequence of ganciclovir use.
2. A patient is prescribed estradiol (Estrace) for hormone replacement therapy (HRT). What should the nurse monitor during this therapy?
- A. Blood glucose levels
- B. Liver function tests
- C. Kidney function tests
- D. Blood pressure
Correct answer: B
Rationale: During estradiol therapy, monitoring liver function tests is essential due to the potential for liver dysfunction. Estradiol can affect liver function, making it crucial to monitor enzyme levels. Choice A, blood glucose levels, is not directly impacted by estradiol therapy, making it an incorrect choice. Choice C, kidney function tests, is not typically affected by estradiol therapy, so it is not the priority for monitoring. Choice D, blood pressure, is also not the primary parameter to monitor during estradiol therapy unless there are pre-existing conditions that warrant such monitoring.
3. What important instruction should the nurse provide regarding the application of testosterone gel in a patient with hypogonadism?
- A. Apply the gel to the chest or upper arms and allow it to dry completely before dressing.
- B. Apply the gel to the face and neck for maximum absorption.
- C. Apply the gel to the genitals for improved results.
- D. Apply the gel to the scalp and back for better results.
Correct answer: A
Rationale: The correct instruction for applying testosterone gel in a patient with hypogonadism is to apply it to the chest or upper arms and allow it to dry completely before dressing. This method helps avoid transfer to others. Applying the gel to the face, neck, or genitals is not recommended as it can lead to unintended exposure to others. Additionally, applying the gel to the scalp and back is not a standard or effective route of administration for testosterone gel. Therefore, choice A is the correct answer as it ensures proper application and safety.
4. A client with multiple sclerosis (MS) is frustrated by tremors associated with the disease. How should the nurse explain why these tremors occur? Due to the demyelination of neurons that occurs in MS:
- A. there is an imbalance in acetylcholine and dopamine, leading to tremors.
- B. there is a disruption in nerve impulse conduction, causing tremors.
- C. muscles are unable to receive impulses, resulting in tremors.
- D. the reflex arc is disrupted, leading to muscle tremors.
Correct answer: B
Rationale: In multiple sclerosis (MS), demyelination of neurons disrupts nerve impulse conduction. This disruption in nerve impulses can lead to tremors, explaining why the client experiences tremors in MS. Choice A is incorrect because tremors in MS are primarily due to nerve conduction issues, not an imbalance in acetylcholine and dopamine. Choice C is incorrect as it oversimplifies the process; the issue lies in nerve impulses, not the muscle's ability to receive them. Choice D is incorrect as the primary cause of tremors in MS is the disruption in nerve impulse conduction, not the reflex arc being disrupted.
5. A male patient with erectile dysfunction is prescribed sildenafil (Viagra). What specific instruction should the nurse provide to ensure the safe use of this medication?
- A. Take the medication with food to prevent nausea.
- B. Avoid taking nitrates while on this medication.
- C. Take the medication at bedtime to ensure absorption during sleep.
- D. Take the medication with milk to enhance absorption.
Correct answer: B
Rationale: The correct instruction the nurse should provide is to avoid taking nitrates while on sildenafil (Viagra). Combining sildenafil with nitrates can result in severe hypotension due to additive vasodilatory effects. Choice A is incorrect because sildenafil can be taken with or without food. Choice C is incorrect as there is no specific requirement to take sildenafil at bedtime. Choice D is incorrect as taking sildenafil with milk has not been shown to enhance its absorption.
