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 observes a UAP bathing a bedfast client with the bed in the high position. Which action should the PN take?

• A. Remain in the room to supervise the UAP
• B. Determine if the UAP would like assistance
• C. Assume care of the client immediately
• D. Instruct the UAP to lower the bed for safety

Correct answer: D

Rationale: The correct action for the PN to take in this situation is to instruct the UAP to lower the bed for safety. Keeping the bed in the lowest position during care activities is crucial for preventing falls and injuries to both the client and the caregiver. Instructing the UAP to lower the bed addresses the immediate safety concern. Choice A is incorrect because simply supervising the UAP without addressing the unsafe bed height does not ensure the client's safety. Choice B is incorrect as the priority is to address the safety concern rather than offering assistance to the UAP. Choice C is incorrect as assuming care of the client immediately does not address the root issue of the high bed position.

3. A female client taking a liquid iron preparation expresses concern that her tooth color has darkened since starting the medication. What action should the PN implement?

• A. Teach the client to use a straw when taking the medication to reduce further tooth staining
• B. Advise the client to withhold further doses until consulting with the healthcare provider
• C. Reassure the client that this change indicates the medication is having the desired effect
• D. Determine if the client is also experiencing mouth or gum pain and difficulty swallowing

Correct answer: A

Rationale: The correct action for the PN to implement is to teach the client to use a straw when taking the medication to reduce further tooth staining. Using a straw minimizes contact between the iron preparation and the teeth, helping prevent additional staining. Choice B is incorrect because withholding doses without consulting the healthcare provider could be detrimental to the client's health. Choice C is incorrect because darkening of tooth color is not an expected effect of liquid iron preparation and should not be reassured as a desired effect. Choice D is incorrect as it does not directly address the client's concern about tooth staining.

4. A client is post-operative day two from a total hip arthroplasty. The nurse notices the surgical wound is red and warm to the touch. What is the most appropriate action?

• A. Apply an ice pack to the incision site.
• B. Monitor the client's temperature.
• C. Document the findings and continue to monitor.
• D. Notify the healthcare provider.

Correct answer: D

Rationale: The correct action when a nurse notices redness and warmth at the surgical wound post total hip arthroplasty is to notify the healthcare provider. These signs may indicate an infection, and prompt evaluation by the healthcare provider is crucial to initiate appropriate treatment. Applying an ice pack (Choice A) may not address the underlying issue of a potential infection. Monitoring the client's temperature (Choice B) is important but not the priority when signs of infection are present. Documenting the findings and continuing to monitor (Choice C) is necessary but should be accompanied by notifying the healthcare provider for further assessment and intervention.

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

• A. Loosen the fistula dressing
• 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: A palpable buzzing sensation, known as a thrill, over an AV fistula indicates proper functioning. The correct action for the PN is to document that the fistula is intact. Choice A is incorrect because there is no need to loosen the fistula dressing when the thrill is felt. Choice B is incorrect as a bounding pulse is not related to the observed buzzing sensation. Choice D is incorrect because applying pressure is unnecessary when a thrill is present, indicating proper AV fistula function.
