Nursing Elites

1. A client post-coronary artery bypass graft (CABG) surgery is concerned about the risk of infection. What is the most important preventive measure the nurse should emphasize during discharge teaching?

• A. Avoid touching the incision sites with bare hands.
• B. Take all prescribed antibiotics as directed.
• C. Report any signs of infection to the healthcare provider immediately.
• D. Keep the incision sites clean and dry.

Correct answer: D

Rationale: The correct answer is D: 'Keep the incision sites clean and dry.' After CABG surgery, maintaining the cleanliness and dryness of the incision sites is crucial to prevent infections. This practice reduces the risk of introducing harmful microorganisms to the surgical wound, promoting healing and preventing complications. Option A, while important, does not fully encompass the preventive measures necessary to avoid infections post-surgery. Option B is significant if antibiotics are prescribed, but ensuring cleanliness directly addresses infection prevention. Option C is reactive and focuses on addressing infection after it occurs, rather than proactively preventing it.

2. What is the primary role of the sinoatrial (SA) node in the heart?

• A. Pacemaker of the heart
• B. Blood pressure regulation
• C. Electrical conduction delay
• D. Stimulating muscle contraction

Correct answer: A

Rationale: The correct answer is A: Pacemaker of the heart. The SA node, known as the natural pacemaker, initiates the electrical impulses that set the rhythm for the heartbeat. It is responsible for coordinating the heart's contractions by generating electrical signals at regular intervals. Choice B is incorrect as the SA node's primary function is not related to blood pressure regulation. Choice C is incorrect as the SA node does not cause electrical conduction delay but rather initiates and conducts the electrical impulses. Choice D is incorrect as the SA node does not directly stimulate muscle contraction but rather initiates the electrical events that lead to muscle contraction.

3. The PN observes a UAP preparing to exit a client's room. The UAP's hands appear visibly soiled as the UAP uses a hand rub for 19 seconds to cleanse the hands. Which action should the PN take?

• A. Confirm that the UAP completed hand hygiene correctly
• B. Instruct the UAP to wash the hands for one minute
• C. Ask the UAP why the hands were so obviously soiled
• D. Advise the UAP to use the hand rub for 30 seconds

Correct answer: D

Rationale: When hands are visibly soiled, they should be washed with soap and water for at least 20 seconds. However, when using hand rub, it should be applied for at least 30 seconds to be effective. In this scenario, the UAP's hands were visibly soiled, indicating the need for thorough cleaning. Advising the UAP to use the hand rub for 30 seconds is essential to ensure proper hand hygiene and reduce the risk of spreading infection. Choices A, B, and C are incorrect because confirming completion of hand hygiene, instructing to wash for one minute, or asking why the hands were soiled do not address the immediate need for proper hand hygiene in the given situation.

4. Which of the following is the best method for confirming nasogastric tube placement?

• A. Auscultating over the stomach while injecting air
• B. Checking the pH of the aspirate
• C. Observing the patient’s response during feeding
• D. Measuring the external length of the tube

Correct answer: B

Rationale: Checking the pH of the aspirate is the most reliable method to confirm nasogastric tube placement as it provides direct evidence of the tube's location in the stomach. When the pH is acidic (pH < 5), it indicates that the tube is correctly placed in the stomach. Auscultating over the stomach while injecting air may not always be accurate, as the sound can be misleading due to various factors. Observing the patient’s response during feeding is not a definitive method for confirming tube placement, as it can be influenced by other factors. Measuring the external length of the tube does not ensure correct placement within the GI tract and can be affected by external factors like patient anatomy.

5. During a clinic visit for a sore throat, a client's basal metabolic panel reveals a serum potassium of 3.0 mEq/L. Which intervention should the PN recommend to the client based on this finding?

• A. Increase intake of dried peaches and apricots
• B. Reduce intake of red meats
• C. Encourage use of a soft toothbrush
• D. Force fluid intake to 1500 mL daily

Correct answer: A

Rationale: The correct answer is to recommend increasing the intake of dried peaches and apricots. A serum potassium level of 3.0 mEq/L is considered low. Increasing the intake of potassium-rich foods can help raise the serum potassium level, preventing complications such as muscle weakness and cardiac arrhythmias. Choice B, reducing intake of red meats, is incorrect because red meats are not specifically related to potassium levels. Choice C, encouraging the use of a soft toothbrush, is unrelated to addressing low potassium levels. Choice D, forcing fluid intake to 1500 mL daily, is not the appropriate intervention for low serum potassium; instead, increasing potassium-rich foods is more beneficial.
