Correct Answer: B

Rationale: The correct answer is to obtain a 12-lead ECG. In a client with a history of angina and reporting chest pain, the priority action is to assess for myocardial infarction, which is best done through an ECG. Administering oxygen, nitroglycerin, or notifying the provider can be important actions but obtaining an ECG takes precedence in evaluating the client's condition.

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: A respiratory rate of 12/min may indicate respiratory depression, a potential side effect of opioid analgesics. Respiratory depression can be a serious complication that requires immediate intervention. Monitoring the respiratory rate is crucial in clients receiving opioids to prevent adverse events. Oxygen saturation, blood pressure, and heart rate are important parameters to assess, but a low respiratory rate is a more critical finding that warrants immediate reporting to the healthcare provider.

Correct Answer: B

Rationale: The correct answer is B. Walking regularly is beneficial for clients with osteoporosis as it helps maintain bone density and prevent fractures. Choice A is not the most appropriate because clients with osteoporosis often require more than just calcium supplements. Choice C is incorrect as weight-bearing exercises actually help strengthen bones. Choice D is important, but walking regularly has a more direct impact on bone health in clients with osteoporosis.
