Correct Answer: A

Rationale: Propylthiouracil (PTU) can suppress bone marrow function, increasing the risk of infection, so it is important to report signs of infection promptly.

Correct Answer: C

Rationale: The correct answer is C: Moon face and buffalo hump. In Cushing's syndrome, excess production of corticosteroids leads to redistribution of fat, particularly in the face (moon face) and between the shoulders (buffalo hump). Hyperpigmentation of the skin is actually associated with Addison's disease, not Cushing's syndrome (choice A). Hypotension is not a typical finding in Cushing's syndrome; instead, hypertension is more commonly seen due to the effects of excess cortisol (choice B). Weight gain, rather than weight loss, is a common symptom of Cushing's syndrome due to the metabolic disturbances caused by excess cortisol (choice D).

Correct Answer: C

Rationale: During an acute gout attack, the healthcare provider is likely to prescribe colchicine. Colchicine is commonly used to treat acute gout attacks because it works by reducing inflammation and alleviating pain associated with the condition. It is important to note that aspirin is not recommended for gout treatment and may even exacerbate the symptoms. Allopurinol and probenecid are medications used for long-term management of gout by reducing uric acid levels in the blood, but they are not typically prescribed during an acute attack. Therefore, colchicine is the most appropriate medication for managing an acute gout attack.

Correct Answer: B

Rationale: The correct instruction for a client scheduled for a colonoscopy is to drink a bowel preparation solution before the procedure. This solution helps cleanse the colon, ensuring clear visualization during the colonoscopy procedure. Choice A is incorrect because a light breakfast is usually recommended the day before the procedure, not on the day of the colonoscopy. Choice C is incorrect as it is important to stay hydrated and follow specific instructions regarding liquid intake. Choice D is incorrect as blood thinners may need to be adjusted or stopped before the colonoscopy to reduce the risk of bleeding during the procedure.

Correct Answer: B

Rationale: In a client with heart failure, decreased pedal edema is a positive indicator of improved cardiac output and reduced fluid retention. Digoxin works by increasing the strength of the heart's contractions, leading to improved circulation and reduced symptoms of heart failure, such as edema. Monitoring for decreased pedal edema is essential to assess the effectiveness of digoxin therapy. Choices A, C, and D are incorrect because an increased heart rate, elevated blood pressure, and improved urine output are not specific indicators of digoxin's effectiveness in managing heart failure. Instead, the focus should be on improvements related to fluid retention and cardiac function, like decreased pedal edema.
