1. Which of the following lab values is elevated first after a client has a myocardial infarction?

• A. LDH
• B. troponin
• C. CPK
• D. SGOT

Correct answer: B

Rationale: The correct answer is troponin. Troponin levels are the most specific and sensitive markers for myocardial infarction, and they begin to rise within a few hours after the event. CPK, SGOT, and LDH are also enzymes that can indicate myocardial damage, but troponin is the earliest and most specific indicator. CPK typically rises 4-8 hours after an infarction, followed by SGOT (AST) at 8-12 hours, and LDH at 12-24 hours post-infarction.

2. When a client has a chest drainage system in place, where should the system be placed?

• A. above the level of the client's chest
• B. at the level of the client's shoulders
• C. at the level of the chest
• D. below the level of the chest

Correct answer: D

Rationale: A chest drainage system should be placed below the level of the client's chest to ensure proper drainage of fluid from the chest. Placing the system above the level of the chest or at the shoulders would not allow gravity to assist in the drainage process, potentially leading to complications such as fluid accumulation. Similarly, placing it at the level of the chest would not create the necessary gravity-dependent flow for effective drainage, which is crucial for the proper functioning of the chest drainage system.

3. A nurse is preparing for the admission of a client with pulmonary tuberculosis. Which action reflects the use of evidence-based practice in the care of the client?

• A. Keeping the door to the client's room closed
• B. Fitting the client for an N95 or HEPA (high-efficiency particulate air) mask to be worn at all times
• C. Placing the client in a semiprivate room with a cohort client
• D. Using a surgical mask when entering the client's room

Correct answer: A

Rationale: Evidence-based practice is an approach to client care that integrates the client's preferences, clinical expertise, and the best research evidence to deliver quality care. In the case of pulmonary tuberculosis, which is transmitted through the airborne route, keeping the door to the client's room closed is crucial to prevent the spread of infection. Placing the client in a semiprivate room with a cohort client is not recommended for airborne precautions; a private room is required to prevent transmission. Fitting the client for an N95 or HEPA mask is essential for the nurse's protection when entering the room, not for the client to wear at all times. Using a surgical mask when entering the client's room is not sufficient for airborne precautions; an N95 or HEPA mask is necessary.

4. A nurse is assisting with data collection of a client who has sustained circumferential burns of both legs. What should the nurse examine first?

• A. Heart rate
• B. Peripheral pulses
• C. Blood pressure (BP)
• D. Radial pulse rate

Correct answer: B

Rationale: The priority assessment for a client with circumferential burns to the legs is to examine peripheral pulses. This is essential to ensure adequate circulation to the extremities. Circumferential burns can lead to compartment syndrome, causing decreased circulation to the affected limbs. Checking peripheral pulses is crucial to monitor for any signs of compromised circulation. While heart rate and blood pressure are important assessments in general, in the context of circumferential burns, the immediate concern is the risk of impaired circulation to the extremities. Therefore, assessing peripheral pulses takes precedence in this situation.

5. After undergoing gastric resection, the client is informed by the nurse that which of the following meals is most likely to cause rapid emptying of the stomach?

• A. a high-protein meal
• B. a high-fat meal
• C. a large meal regardless of nutrient content
• D. a high-carbohydrate meal

Correct answer: D

Rationale: After gastric resection, meals high in carbohydrates are more likely to cause rapid emptying of the stomach. Carbohydrates stimulate the release of gastrin, which accelerates gastric emptying. On the other hand, high-fat and high-protein meals tend to delay gastric emptying. A large meal, regardless of nutrient content, can also delay gastric emptying due to the increased volume of food that needs to be processed.
