Correct Answer: C

Rationale: The pain of a myocardial infarction (MI) is often accompanied by shortness of breath and feelings of fear or anxiety. Unlike stable angina, the pain of an MI typically lasts longer than 15 minutes and is not relieved by nitroglycerin. Additionally, it can occur without a known cause, unlike stable angina which often has a trigger such as exertion.

Correct Answer: B

Rationale: The client's symptoms of a pounding headache and blurred vision are indicative of autonomic dysreflexia, a potentially life-threatening condition in clients with spinal cord injuries at T6 or above. The nurse's priority action should be to check the client's blood pressure as autonomic dysreflexia can lead to severe hypertension. Identifying and addressing this elevated blood pressure promptly is crucial to prevent serious complications such as seizures, stroke, or even death. Once the blood pressure is assessed and managed, further interventions can be implemented to address the underlying cause of autonomic dysreflexia.

Correct Answer: B

Rationale: The priority for a nurse working on an inpatient medical-surgical unit is to ensure client safety. This is crucial as errors in hospital care can lead to preventable deaths. While attending to holistic client needs and providing client-focused care are important aspects of nursing, ensuring client safety takes precedence to prevent harm and promote positive patient outcomes.

Correct Answer: B

Rationale: Patients prescribed carbidopa-levodopa should be informed that it may take several weeks for the medication to reach its full therapeutic effectiveness in managing Parkinson's disease symptoms. This delayed onset of action is important for patients to be aware of to prevent premature discontinuation of the medication due to perceived lack of efficacy.

Correct Answer: B

Rationale: Absent breath sounds may indicate a pneumothorax, a serious complication post lung biopsy. This condition requires immediate attention to prevent respiratory distress.
