Correct Answer: A

Rationale: The correct answer is A because it demonstrates data validation in the nursing clinical decision-making process. The nurse assesses the time of the last dressing change and observes old and new drainage, which are relevant data points for wound care. This approach ensures that the decision to remove the dressing is based on accurate and validated information, leading to appropriate patient care. Choice B is incorrect because it relies on subjective information (increased pain and family request) rather than objective data validation. Choice C is incorrect as it involves a direct request for an order without sufficient data validation. Choice D is incorrect because elevating a leg cast based solely on a patient's report of decreased mobility does not involve thorough data validation related to the specific care needed for the patient's condition.

Correct Answer: C

Rationale: Rationale: 1. Pulmonary edema is caused by increased hydrostatic pressure in the pulmonary circulation. 2. Elevated left ventricular end-diastolic pressure signifies heart failure, a common cause of pulmonary edema. 3. A rise in pulmonary venous pressure is a consequence of increased hydrostatic pressure. Therefore, all three alterations (A, B, D) are characteristic of pulmonary edema. Option C is correct. Choices A, B, and D are incorrect because they are all individually associated with pulmonary edema and collectively represent the condition.

Correct Answer: A

Rationale: The correct answer is A: Shrimp and tomatoes. Shrimp is a good source of heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based foods. Tomatoes are rich in Vitamin C, which helps enhance iron absorption. Cheese, bananas, lobster, squash, lamb, and peaches do not provide significant amounts of iron essential for an anemic client. The combination of shrimp and tomatoes offers a balanced approach to increase iron levels effectively.

Correct Answer: B

Rationale: The correct answer is B: Respiratory acidosis. Aspirin can lead to respiratory acidosis due to its effect on the respiratory center in the brainstem. It causes hyperventilation, leading to respiratory alkalosis initially, followed by respiratory acidosis as compensation mechanism fails. Weight gain is not a typical adverse reaction of aspirin. Fine motor tremors are not associated with aspirin therapy. Bilateral hearing loss is a rare but serious side effect of aspirin overdose, not prolonged therapy.

Correct Answer: A

Rationale: The correct answer is A: Urinary output of 30 ml in an hour. Adequate tissue perfusion is best indicated by a sufficient urinary output, as it demonstrates proper kidney perfusion and function. A low urinary output may suggest inadequate perfusion. Explanation for other choices: B: Central venous pressure reading of 2 cm H20 is not a reliable indicator of tissue perfusion to vital organs. C: Pulse rates alone are not enough to indicate tissue perfusion as they can be influenced by various factors. D: Blood pressure readings alone may not accurately reflect tissue perfusion, especially in the context of fluid replacement therapy.
