Correct Answer: B

Rationale: The correct answer is to administer nitroglycerin. Nitroglycerin is the priority intervention for a patient presenting with chest pain as it helps dilate blood vessels, reduce chest pain, and improve oxygen supply to the heart. Obtaining a detailed medical history, conducting an ECG, or administering morphine sulfate are important steps in the assessment and treatment process but are secondary to the immediate need to address chest pain and potential cardiac ischemia.

Correct Answer: B

Rationale: Covering the tracheostomy when outside is crucial as it helps prevent dust and other irritants from entering the airway, reducing the risk of complications. Cleaning with alcohol (choice A) can be too harsh for the skin around the tracheostomy site. While replacing the tube weekly (choice C) is important, it is typically done by healthcare providers. Using tap water to clean (choice D) is not recommended as it may introduce contaminants to the tracheostomy site.

Correct Answer: A

Rationale: The main components of a comprehensive discharge plan for a patient with heart failure include advising on appropriate physical activity and exercise to improve cardiovascular health and overall well-being. While fluid restriction and dietary recommendations are important aspects of heart failure management, advising on physical activity and exercise is crucial for improving cardiac function and quality of life post-discharge. Medication management is also essential but focusing on physical activity is particularly relevant for long-term management and preventing readmissions.

Correct Answer: D

Rationale: Notifying the provider of the client's shellfish allergy is crucial to prevent a potential reaction from the contrast dye. While attaching a wristband indicating the allergy may be necessary, the priority is to inform the provider. Asking the client about other foods causing a similar reaction or notifying the dietary department, although important, are not the priority in this situation.

Correct Answer: A

Rationale: The correct answer is A: Log out of the computer terminal before leaving. Logging out before leaving the computer terminal is crucial to ensuring patient data remains confidential and to prevent unauthorized access. Choice B is incorrect because sharing passwords compromises confidentiality. Choice C is incorrect as changing passwords regularly, although a good practice for security, is not directly related to maintaining client confidentiality. Choice D is incorrect as it does not address the immediate concern of maintaining client confidentiality through proper access to electronic medical records.
