Correct Answer: A

Rationale: The correct answer is A: Urine output of 20 mL/hr. A urine output less than 30 mL/hr can indicate decreased renal perfusion, potentially due to hypovolemia or other issues, and should be reported to the provider. B: A temperature of 36.5°C (97.7°F) falls within the normal range and does not require immediate reporting. C: Sanguineous drainage on the surgical dressing is expected in the early postoperative period and should be monitored but does not need immediate reporting unless excessive. D: A WBC count of 9,000/mm3 is within the normal range and does not indicate an immediate concern.

Correct Answer: B

Rationale: The correct first action for a client with an NG tube experiencing nausea and decreased gastric secretions is to irrigate the NG tube with sterile water. This helps alleviate blockages and can improve the client's symptoms. Increasing the suction pressure (Choice A) may exacerbate the issue and cause further discomfort. Turning the client onto their left side (Choice C) is not directly related to addressing the reported symptoms. Replacing the NG tube with a new one (Choice D) should be considered only after attempting initial interventions like irrigation.

Correct Answer: A

Rationale: Muscle weakness is a characteristic finding in hyperkalemia. High levels of potassium can affect the normal function of muscles, leading to weakness. Nausea and increased thirst are not typically associated with hyperkalemia. Restlessness is more commonly seen in conditions such as hypoxia or anxiety, not specifically in hyperkalemia.

Correct Answer: D

Rationale: The correct answer is D: Consumption of contaminated food. Hepatitis A is primarily transmitted through the ingestion of contaminated food or water. Airborne droplets and sexual contact are not common modes of transmission for hepatitis A. While contact with contaminated surfaces can play a role in the spread of some infections, hepatitis A is not typically transmitted through this route.

Correct Answer: C

Rationale: The correct answer is C: Decreased bowel sounds. In hypokalemia, decreased bowel sounds are common due to slowed peristalsis. Hyperactive reflexes (choice A) and increased deep tendon reflexes (choice D) are more indicative of hyperkalemia. A strong, bounding pulse (choice B) is not typically associated with hypokalemia.
