Correct Answer: A

Rationale: The correct answer is to observe for facial expressions when assessing pain in a non-verbal patient. Facial expressions can provide vital clues about the patient's pain level and discomfort. Choices B and C, observing for restlessness and sweating, can be less specific and may indicate other issues besides pain. Choice D, checking for non-verbal cues, is too broad and does not specify the crucial aspect of focusing on facial expressions.

Correct Answer: B

Rationale: The most appropriate nursing intervention for a patient experiencing hypoglycemia is to administer oral glucose. Oral glucose is usually sufficient for treating mild hypoglycemia and can be administered quickly and easily. Administering IV glucose (Choice A) is reserved for severe cases where the patient is unable to swallow or unconscious. Checking blood sugar in 15 minutes (Choice C) is important but providing glucose should come first. Providing a high-calorie snack (Choice D) may not be as rapidly effective as administering oral glucose in quickly raising blood sugar levels in a patient experiencing hypoglycemia.

Correct Answer: D

Rationale: In a client with a history of angina experiencing chest pain radiating to the left arm, obtaining a 12-lead ECG is the priority action to assess for myocardial infarction. An ECG helps in diagnosing and evaluating the extent of cardiac ischemia or infarction. Administering nitroglycerin, oxygen, or aspirin can follow once the ECG has been performed to confirm the diagnosis and guide further interventions. Administering nitroglycerin sublingually is often appropriate for angina but should not precede the ECG in this urgent scenario. Oxygen therapy and aspirin administration are important interventions but obtaining the ECG takes precedence in assessing for acute cardiac events.

Correct Answer: A

Rationale: The correct answer is to monitor vital signs. Post-operative patients need close monitoring of their vital signs to detect early signs of complications such as changes in blood pressure, heart rate, temperature, and respiratory rate. While monitoring the surgical site is also important for signs of infection, assessing vital signs takes precedence as it provides immediate information about the patient's overall condition. Checking blood glucose levels may be essential for specific patients but is not the primary assessment for monitoring post-op complications. Checking for abnormal breath sounds is important but falls secondary to monitoring vital signs as it indicates respiratory issues rather than providing a comprehensive assessment of the patient's condition.

Correct Answer: A

Rationale: When a healthcare provider discovers a patient has fallen, the primary action should be to assess the patient for injuries. This is crucial to determine the extent of harm and if immediate treatment is necessary. Calling for help is important, but assessing the patient's condition takes precedence to ensure the patient's safety and well-being. While documenting the fall and notifying the healthcare provider are essential steps, they come after assessing the patient's injuries.
