By asking the parents to step out, the nurse creates a safe space for the girl to discuss any sensitive issues. Choice A may inhibit the girl's honest communication. Choice B risks the parents dominating the conversation. Choice C may make the girl uncomfortable discussing personal matters in front of her parents.

Correct Answer: C

Rationale: The correct answer is C: Respiratory depression. After a stroke, the patient may experience impaired breathing due to neurological damage affecting the respiratory center in the brain. Monitoring for signs of respiratory depression, such as shallow breathing or decreased oxygen saturation, is crucial to prevent respiratory failure. Severe headache (A) may be a symptom of stroke but is not the highest priority for monitoring. Dehydration (B) is important to prevent but not typically a direct consequence of stroke. Sudden loss of vision (D) may occur with certain types of strokes but is not as critical to monitor as respiratory depression.

Correct Answer: A

Rationale: The correct answer is A: Encouraging early ambulation. Early ambulation helps prevent complications such as deep vein thrombosis and pulmonary embolism by improving circulation and preventing blood clots. It also promotes joint mobility and muscle strength. Providing pain medication (B) is important but not as crucial as preventing complications. Monitoring for signs of infection (C) is essential but not the most important intervention. Administering antibiotics before surgery (D) does not directly prevent post-operative complications related to knee replacement.

Correct Answer: B

Rationale: The correct interpretation of a drumlike sound heard during percussion of the abdomen is that it indicates air-filled areas within the abdomen. This sound, known as tympany, occurs when air is present in the gastrointestinal tract or hollow organs. Percussion produces a resonant, drum-like sound over these air-filled areas. This is a normal finding during a physical examination. Incorrect Answers: A: Constipation does not typically produce a drumlike sound during percussion. Constipation may cause a dull sound due to fecal matter retention. C: The presence of a tumor would not cause a drumlike sound during percussion. Tumors are typically solid masses and would produce a dull sound during percussion. D: Dense organs such as the liver or spleen would produce a dull sound, not a drumlike sound, during percussion due to their solid nature.

Correct Answer: C
