Nursing Elites

1. 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.

2. The PN is caring for a client who had an acute brain attack with resulting expressive aphasia and urinary incontinence. To ensure care for the client, which task should the PN delegate to the UAP?

• A. Explain how to use a communication board
• B. Document progress in the use of the communication board
• C. Encourage voiding by assisting the client to the bedside commode
• D. Establish a bladder training schedule and methods

Correct answer: C

Rationale: Assisting the client to the bedside commode is an appropriate task for the UAP as it involves basic patient care and mobility assistance, which are within the UAP's scope of practice. Options A and B involve communication techniques and documentation, which are more appropriate for licensed nursing staff. Option D involves establishing a bladder training schedule, which requires assessment and planning skills beyond the UAP's role.

3. When caring for a patient with a chest tube, which nursing action is most important?

• A. Clamping the chest tube every 2 hours to prevent air leaks
• B. Keeping the drainage system below chest level
• C. Emptying the drainage system every hour to prevent backflow
• D. Removing the chest tube when drainage decreases significantly

Correct answer: B

Rationale: The most crucial nursing action when caring for a patient with a chest tube is to keep the drainage system below chest level (choice B). This position helps ensure proper drainage and prevents backflow of fluid or air into the pleural space, promoting optimal functioning of the chest tube. Clamping the chest tube every 2 hours (choice A) is incorrect as it can obstruct the drainage system and lead to complications. Emptying the drainage system every hour (choice C) is unnecessary unless there are specific clinical indications. Removing the chest tube when drainage decreases significantly (choice D) is also incorrect as the decision should be based on overall clinical assessment rather than drainage amount alone.

4. Which of the following dietary modifications should be recommended for a patient with chronic kidney disease (CKD)?

• A. High protein, low sodium
• B. Low protein, high potassium
• C. Low sodium, low potassium
• D. High calcium, low phosphorus

Correct answer: C

Rationale: A low sodium, low potassium diet is often recommended for patients with CKD to manage fluid balance and prevent electrolyte imbalances that the kidneys can no longer regulate effectively. High protein diets, as mentioned in choice A, can put extra strain on the kidneys, making it an incorrect choice. Choice B, which suggests a low protein, high potassium diet, is also incorrect because high potassium levels can be harmful to individuals with CKD. Choice D, advocating for a high calcium, low phosphorus diet, is not the typical dietary recommendation for CKD patients, even though managing calcium and phosphorus levels is important in their diet.

5. At the end of a 12-hour shift, the PN observes the urine in a client's drainage bag as seen in the picture. Which action should the PN take next?

• A. Offer to administer a prescribed PRN analgesic
• B. Obtain a finger stick capillary glucose level
• C. Determine if the client's bladder feels distended
• D. Note the most recent white blood cell count

Correct answer: D

Rationale: Noting the white blood cell count is the most appropriate action in this situation. Changes in urine appearance could indicate infection, and assessing the white blood cell count helps in evaluating the possibility of infection. This is crucial for understanding the client's overall condition. The other options are not directly related to assessing infection based on urine appearance. Offering analgesics, checking glucose levels, or determining bladder distention may not address the underlying issue of a potential infection.
