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: C

Rationale: The correct answer is C because clients taking metformin should avoid alcohol as it increases the risk of lactic acidosis. Choices A, B, and D are incorrect. Choice A is not specific to metformin but rather a general recommendation for some medications. Choice B is a good practice for medication adherence but does not relate specifically to metformin. Choice D is inaccurate as weight gain is not an expected side effect of metformin.

Correct Answer: A

Rationale: The most appropriate action when a patient is experiencing severe dehydration is to administer IV fluids. This intervention is crucial in rapidly correcting dehydration and restoring fluid balance. Encouraging oral fluids may not be sufficient in cases of severe dehydration where intravenous rehydration is needed. Monitoring electrolytes is important but administering fluids takes precedence in severe dehydration. Performing a neurological exam is not the primary intervention for severe dehydration.

Correct Answer: C

Rationale: The correct answer is C. A heart rate of 88/min is a normal finding; therefore, it does not require immediate reporting to the provider. The respiratory rate of 20/min, blood pressure of 118/76 mm Hg, and oxygen saturation of 94% are also within normal ranges and do not indicate any immediate concerns. However, a serum potassium level of 3.0 mEq/L indicates hypokalemia, which can be a serious issue and should be reported to the provider for further evaluation and management.

Correct Answer: C

Rationale: The correct answer is C: Leafy green vegetables. Leafy green vegetables are rich in calcium, which is essential for bone health and can help prevent bone loss in clients with osteoporosis. Carrots (choice A), while nutritious, are not as high in calcium as leafy green vegetables. Milk (choice B) is also a good source of calcium but may not be suitable for clients who are lactose intolerant. Bananas (choice D) are a healthy fruit choice but do not provide significant amounts of calcium needed for osteoporosis.
