Correct Answer: A

Rationale: The correct answer is A: Urine output increased. Furosemide is a loop diuretic that works by increasing urine output, thus helping to reduce fluid volume in the body. This effect is crucial in managing conditions like heart failure and edema. Increased urine output indicates that the medication is working as intended. Choice B: Heart rate increased is incorrect as furosemide does not directly affect heart rate. Choice C: Serum potassium decreased is incorrect as furosemide can lead to potassium loss, but this is not the primary indicator of its effectiveness. Choice D: Pulse pressure increased is incorrect as furosemide does not typically impact pulse pressure.

Correct Answer: B

Rationale: The correct answer is B: Fluid retention and weight gain. Prednisone is a corticosteroid that can cause fluid retention and weight gain as common adverse reactions. Here's the rationale: Prednisone is known to increase sodium and water retention in the body, leading to fluid retention and subsequent weight gain. This occurs due to the drug's impact on the body's electrolyte balance. Tetany and tremors (Choice A) are not common adverse reactions associated with prednisone use. Anorexia and weight loss (Choice C) are also not typical reactions, as prednisone is more likely to cause weight gain. Choice D, "None of the above," is incorrect as prednisone commonly causes fluid retention and weight gain as adverse reactions.

Correct Answer: A

Rationale: The correct answer is A: A urine output of 400 ml in 8 hours indicates a fluid and electrolyte imbalance induced by chemotherapy. Chemotherapy can cause renal damage, leading to decreased urine output. This can result in fluid retention and electrolyte imbalances. Choice B is incorrect because a serum potassium level of 3.6 mEq/L is within the normal range. Choice C is incorrect as the blood pressure readings provided are within the normal range. Choice D is incorrect as dry oral mucous membranes and cracked lips are more indicative of dehydration rather than a fluid and electrolyte imbalance induced by chemotherapy.

Correct Answer: B

Rationale: The correct answer is B: Pericardial friction rub. This is a key diagnostic sign of pericarditis due to the inflammation of the pericardial layers causing a rough, grating sound heard upon auscultation. Precordial pain (A) is a common symptom but not a specific diagnostic sign. Hypotension (C) and rapid/labored respirations (D) are not typically associated with pericarditis. Therefore, the presence of a pericardial friction rub is crucial in confirming the diagnosis of pericarditis.

Correct Answer: C

Rationale: The correct answer is C: Obesity. Obesity is a known risk factor for colon cancer as it can lead to chronic inflammation and changes in hormone levels, increasing the risk of developing cancerous cells in the colon. Smoking (choice A) is more strongly associated with lung cancer. Heavy alcohol consumption (choice B) is linked to increased risk of liver and esophageal cancer, not colon cancer. Saccharin consumption (choice D) has not been definitively linked to colon cancer. In summary, obesity is the most relevant risk factor for colon cancer among the choices provided.
