Correct Answer: C

Rationale: The correct answer is C: Pneumonia. Early postoperative ambulation helps prevent pneumonia by promoting lung expansion, increasing oxygenation, and preventing atelectasis. A: Increased peristalsis is unrelated to ambulation. B: Coughing is important for airway clearance but not directly related to ambulation. D: Wound healing is influenced by various factors, but ambulation primarily impacts respiratory function.

Correct Answer: A

Rationale: The correct answer is A: emergency. Acute appendicitis is a condition that requires immediate surgical intervention to prevent complications like rupture. In an emergency surgery, the procedure must be done urgently to treat a life-threatening condition. In this case, the patient's symptoms indicate an urgent need for surgery to remove the inflamed appendix. Choice B: urgent, implies that surgery is needed promptly, but not immediately to prevent life-threatening complications. Choice C: elective, refers to a planned, non-urgent surgery that is scheduled in advance. Choice D: required, is a vague term and doesn't specify the urgency of the surgery, hence it is not the best classification for acute appendicitis surgery.

Correct Answer: C

Rationale: The correct answer is C: Hypercalcemia. Increased thirst and polyuria are symptoms of hypercalcemia, as excess calcium can lead to dehydration and increased urine output. Decreased muscle tone is also a common symptom of hypercalcemia. The lab value of Ca 8 mg/dl confirms high levels of calcium in the blood. Incorrect choices: A: Hypocalcemia - This is incorrect as the lab value of Ca 8 mg/dl indicates normal to high levels of calcium, ruling out hypocalcemia. B: Hyperkalemia - This is incorrect as the lab value of K 4 mEq/L is within normal range, ruling out hyperkalemia. D: Hypochloremia - This is incorrect as the lab value of Cl 103 mEq/L is within normal range, ruling out hypochloremia.

Correct Answer: C

Rationale: The correct answer is C: 0.45% saline. This solution is hypotonic because it has a lower osmolarity compared to the intracellular fluid. It contains fewer solutes than the cells, causing water to move into the cells by osmosis, potentially causing them to swell. Normal saline (A) and Ringer's lactate (B) are isotonic solutions, meaning they have a similar osmolarity to the intracellular fluid and do not cause significant water shifts. 5% dextrose in normal saline (D) is a hypertonic solution, containing more solutes than the cells, leading to water movement out of the cells.

Correct Answer: A

Rationale: The correct answer is A because during the first phase of the nursing process (assessment), the nurse gathers a comprehensive database of information about the patient's health status. This step is crucial for identifying the patient's needs and developing a holistic care plan. Choice B is incorrect because identifying nursing diagnoses typically occurs in the second phase (diagnosis). Choice C is incorrect as intervening based on care priorities happens in the third phase (planning and implementation). Choice D is incorrect as determining outcomes achieved is part of the final phase (evaluation).
