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. 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.

3. While caring for a client with an AV fistula in the left forearm, the nurse observed a palpable buzzing sensation over the fistula. What action should the nurse take?

• A. Loosen the dressing of the fistula
• B. Report the presence of a bounding pulse
• C. Document that the fistula is intact
• D. Apply gentle pressure over the site

Correct answer: C

Rationale: The correct answer is C: Document that the fistula is intact. The palpable buzzing sensation (known as a thrill) over the AV fistula indicates proper functioning. It is essential for the nurse to document this finding to ensure ongoing monitoring of the fistula's status. Choices A, B, and D are incorrect. Choice A is incorrect because there is no indication to loosen the dressing. Choice B is incorrect as a bounding pulse is not associated with the palpable buzzing sensation of a thrill. Choice D is incorrect as applying pressure over the site is not necessary for this situation.

4. The nurse is performing a psychosocial assessment on an adolescent aged 14. Which emotional response is typical during early adolescence?

• A. Frequent anger
• B. Cooperativeness
• C. Moodiness
• D. Combativeness

Correct answer: C

Rationale: Moodiness is a typical emotional response during early adolescence. Hormonal changes and developmental challenges contribute to this behavior. While anger and combativeness can also be present during adolescence, they are not as consistently typical as moodiness. Cooperativeness, on the other hand, is a trait more commonly associated with later stages of development and maturity, rather than early adolescence.

5. A nurse who receives a patient in the operative suite prior to the actual surgery is in charge of the patient’s care. Which of the following is NOT a task related to the nurse’s intraoperative care?

• A. Go over the surgical procedure with the patient before he or she is anesthetized
• B. Strictly adhere to asepsis during all intraoperative procedures
• C. Provide emotional support to the patient and their family
• D. Monitor the patient’s physical status

Correct answer: A

Rationale: The correct answer is A. Going over the surgical procedure with the patient is typically done preoperatively, not intraoperatively. Intraoperative tasks of a nurse involve strictly adhering to asepsis during procedures, monitoring the patient's physical status, and providing emotional support to the patient and their family during the surgery. Choices B, C, and D are all tasks that are directly related to the nurse's responsibilities during the intraoperative phase of care.
