Correct Answer: C

Rationale: Positioning the client with the head of the bed elevated at 45 degrees is crucial during enteral feedings to prevent aspiration. This position helps reduce the risk of regurgitation and aspiration of feedings into the lungs. Option A is not necessary before feedings. Placing the client in a supine position (Option B) increases the risk of aspiration. Checking gastric residuals every 8 hours (Option D) is important but not directly related to positioning during enteral feedings.

Correct Answer: A

Rationale: Corrected Rationale: Daily weight monitoring is the most accurate way to assess fluid balance in patients receiving diuretics. Monitoring daily weight allows healthcare providers to track changes in fluid status more precisely. While monitoring intake and output (choice B) is essential, it may not provide a comprehensive picture of overall fluid balance. Monitoring blood pressure (choice C) is important but may not directly reflect fluid balance. Checking for edema (choice D) is useful but may not be as sensitive as daily weight monitoring in assessing fluid balance.

Correct Answer: A

Rationale: The appropriate action when a patient presents with chest pain is to administer aspirin. Aspirin helps reduce the risk of clot formation by inhibiting platelet aggregation, which can be beneficial in cases of myocardial infarction. Nitroglycerin is commonly used for chest pain related to angina but is not the first-line treatment for all types of chest pain. Repositioning the patient may be necessary for comfort or assessment but is not the immediate priority. Surgery is not typically the first-line intervention for chest pain unless there are specific indications.

Correct Answer: B

Rationale: The correct answer is B. A weight gain of 1 kg (2.2 lb) in 24 hours is concerning as it indicates fluid retention, which can be a sign of complications in clients receiving chemotherapy. Rapid weight gain can be associated with conditions like fluid overload or electrolyte imbalances, which need prompt medical attention. Choices A, C, and D are not typically immediate concerns related to chemotherapy. Alopecia (choice A) is a common side effect of chemotherapy, a white blood cell count of 6,000/mm³ (choice C) falls within the normal range, and a temperature of 37.2°C (99°F) (choice D) is slightly elevated but not a critical finding in this context.

Correct Answer: A

Rationale: Monitoring oxygen saturation is crucial in assessing a patient with respiratory distress because it helps determine if the patient is receiving adequate oxygen. Oxygen saturation levels provide immediate feedback on the efficiency of oxygen delivery to the tissues. Checking for abnormal breath sounds (Choice B) is relevant in respiratory assessments, but it is secondary to assessing oxygen saturation. Pitting edema (Choice C) and performing a neurological exam (Choice D) are not directly related to assessing respiratory distress and are not the primary focus when managing a patient with breathing difficulties.
