1. A client with hyperthyroidism is prescribed methimazole. The nurse should instruct the client that the purpose of this medication is to:
- A. Decrease thyroid hormone production
- B. Increase thyroid hormone production
- C. Suppress the immune system
- D. Prevent thyroid storm
Correct answer: A
Rationale: The correct answer is A: Decrease thyroid hormone production. Methimazole works by inhibiting the synthesis of thyroid hormones, specifically by blocking the enzyme responsible for this process. By reducing the production of thyroid hormones, methimazole helps to normalize the elevated levels seen in hyperthyroidism. Choices B, C, and D are incorrect. Choice B, 'Increase thyroid hormone production,' is inaccurate as methimazole actually decreases thyroid hormone production. Choice C, 'Suppress the immune system,' is unrelated to the mechanism of action of methimazole. Choice D, 'Prevent thyroid storm,' is not the primary purpose of methimazole; while it may help prevent worsening of hyperthyroidism, its main action is to reduce thyroid hormone levels.
2. A 60-year-old male client had a hernia repair in an outpatient surgery clinic. He is awake and alert, but has not been able to void since he returned from surgery 6 hours ago. He received 1000 mL of IV fluid. Which action would be most likely to help him void?
- A. Have him drink several glasses of water
- B. Crede the bladder from the bottom to the top
- C. Assist him to stand by the side of the bed to void
- D. Wait 2 hours and have him try to void again
Correct answer: C
Rationale: Assisting the client to stand by the side of the bed to void is the most appropriate action. This position can help stimulate voiding due to gravity and normal positioning. Having the client drink water (Choice A) may help, but assisting him to stand is more effective. Crede maneuver (Choice B) is not recommended as it can increase the risk of bladder trauma. Waiting for 2 hours (Choice D) without taking any action is not proactive in addressing the client's inability to void.
3. A client with Cushing's syndrome is being monitored for complications. Which of the following findings should the nurse report to the healthcare provider immediately?
- A. Hypertension
- B. Hyperglycemia
- C. Low-grade fever
- D. Weight gain
Correct answer: C
Rationale: The correct answer is C: Low-grade fever. A low-grade fever may indicate an infection, which is a serious concern in clients with Cushing's syndrome due to their immunosuppressed state. Hypertension and hyperglycemia are common manifestations of Cushing's syndrome and may not require immediate reporting unless severe or uncontrolled. Weight gain is also a common symptom in clients with Cushing's syndrome and may not warrant immediate reporting unless it is sudden and significant.
4. A client with hyperthyroidism is receiving radioactive iodine therapy. The nurse should monitor for which of the following side effects?
- A. Hypothyroidism
- B. Hyperkalemia
- C. Hyponatremia
- D. Hypercalcemia
Correct answer: A
Rationale: The correct answer is A: Hypothyroidism. Radioactive iodine therapy is used to treat hyperthyroidism by destroying thyroid tissue and reducing hormone production. This can lead to an underactive thyroid, resulting in hypothyroidism. Hyperkalemia (choice B) is an elevated potassium level, usually not associated with radioactive iodine therapy. Hyponatremia (choice C) is a low sodium level, which is also not a common side effect of this therapy. Hypercalcemia (choice D) is an elevated calcium level, unrelated to radioactive iodine therapy for hyperthyroidism.
5. The client with breast cancer is receiving cyclophosphamide (Neosar). The nurse is reinforcing medication instructions and advises the client to:
- A. Take the medication with food.
- B. Increase fluid intake to 2000 to 3000 mL daily.
- C. Decrease sodium intake while taking the medication.
- D. Increase potassium intake while taking the medication.
Correct answer: B
Rationale: The correct answer is to increase fluid intake to 2000 to 3000 mL daily. Cyclophosphamide can cause hemorrhagic cystitis as a toxic effect. By increasing fluid intake, the client can help prevent this complication by promoting frequent urination, which reduces the concentration of the drug and its metabolites in the bladder. This dilution effect can help reduce the risk of bladder toxicity.
