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 who is at full-term gestation is in active labor and complains of a cramp in her leg. Which intervention should the PN implement?

• A. Massage the calf and foot
• B. Elevate the leg above the heart
• C. Check the pedal pulse in the affected leg
• D. Extend the leg and flex the foot

Correct answer: D

Rationale: During labor, muscle cramps are common due to prolonged muscle tension. The correct intervention to alleviate a cramp in the leg is to extend the leg and flex the foot. This action helps relieve the muscle spasm by stretching and contracting the muscles. Massaging the calf and foot (Choice A) may not be as effective in relieving the cramp as extending and flexing the leg. Elevating the leg above the heart (Choice B) is not necessary and may not directly address the cramp. Checking the pedal pulse (Choice C) is important for assessing circulation, but it does not directly address the muscle cramp.

3. The home health PN suspects elder abuse after observing fresh lacerations on the arms and legs of an older adult male client who lives with his daughter. Which action is most important for the PN to take?

• A. Document the lacerations in the client's record
• B. Report findings to the supervisor for referral to adult protective services
• C. Ask the daughter who has been taking care of the client on a daily basis
• D. Apply dry dressings after cleansing the wounds

Correct answer: B

Rationale: The most important action for the PN to take in this situation is to report the findings to the supervisor for referral to adult protective services. Suspected elder abuse must be reported promptly to ensure the safety and protection of the client. Documenting the lacerations in the client's record is important but not as critical as reporting the suspected abuse. Asking the daughter who is the potential abuser may not yield accurate information and could compromise the safety of the client. Applying dressings to the wounds is a lower priority compared to addressing the suspected elder abuse.

4. 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.

5. A client on bedrest refuses to wear the prescribed pneumatic compression devices after surgery. Which action should the PN implement in response to the client's refusal?

• A. Emphasize the importance of active foot flexion
• B. Check the surgical dressing
• C. Complete an incident report
• D. Explain the use of an incentive spirometer every 2 hours

Correct answer: A

Rationale: The correct action for the PN to implement when a client refuses pneumatic compression devices is to emphasize the importance of active foot flexion. Active foot flexion exercises can help prevent deep vein thrombosis (DVT) in clients who are not using the compression devices. Encouraging some form of circulation-promoting activity is crucial to reduce the risks associated with immobility. Checking the surgical dressing (Choice B) is important but not the immediate action to address the refusal of compression devices. Completing an incident report (Choice C) is not necessary in this situation as the client's refusal is not an incident. Explaining the use of an incentive spirometer (Choice D) is not directly related to addressing the refusal of compression devices for DVT prevention.
