1. What is the primary purpose of conducting an epidemiologic investigation?

Correct answer: A

Rationale: The primary purpose of conducting an epidemiologic investigation is to delineate the etiology of the epidemic, which involves identifying the cause or origin of the disease outbreak. This process helps in understanding how the disease spreads, its risk factors, and developing strategies for control and prevention.

2. A client who decides not to have surgery despite significant blockages in his coronary arteries is an example of what principle?

Correct answer: B

Rationale: The correct answer is B: Autonomy. Autonomy in healthcare refers to respecting a patient's right to make decisions about their own care, even if those decisions may not align with healthcare providers' recommendations. In this scenario, the client's decision not to have surgery despite significant blockages in his coronary arteries demonstrates his autonomy in making choices about his own health. Choice A, Fidelity, refers to the concept of keeping promises and being faithful to commitments, which is not applicable in this situation. Choice C, Justice, involves fairness and equal treatment in healthcare, which is not the primary principle at play when a patient exercises autonomy. Choice D, Non-maleficence, relates to the principle of doing no harm, which is important but not directly relevant to the client's decision to refuse surgery.

3. A healthcare provider is assessing a client who has a heart rate of 40/min. The client is diaphoretic and has chest pain. Which of the following medications should the healthcare provider plan to administer?

Correct answer: C

Rationale: The client presents with bradycardia, diaphoresis, and chest pain, indicating reduced cardiac output. Atropine is the appropriate choice as it increases heart rate by blocking the parasympathetic nervous system. Lidocaine is used for ventricular arrhythmias, Adenosine for supraventricular tachycardia, and Verapamil for controlling heart rate in atrial fibrillation or atrial flutter. These medications are not suitable for the client's current presentation.

4. A community health nurse is teaching a group of clients about first aid for wounds. Which client statement indicates understanding?

Correct answer: B

Rationale: The correct answer is B. Applying clean dressings over blood-saturated ones and holding pressure helps to control bleeding and prevent tissue disruption. Removing blood-saturated dressings can cause further damage by disrupting the forming clot. Elevating the wound above heart level is beneficial to reduce swelling, but it is not the best immediate action for a blood-saturated dressing. Leaving the wound open to air can increase the risk of infection and slow down the healing process.

5. A nurse working with a population of black clients is cognizant that some health conditions are more prevalent in this population than in the white population and is working to address them. Which health assessment would be the priority for this client population?

Correct answer: B

Rationale: Hypertension is the most prevalent health problem among black Americans. A blunted nocturnal response is one factor responsible for this problem.
