Nursing Elites

1. The PN identifies an electrolyte imbalance, exhibited by changes in mental status, and an elevated blood pressure for a client with progressive heart disease. Which intervention should the PN implement first?

• A. Record usual eating patterns
• B. Evaluate for muscle cramping
• C. Document abdominal girth
• D. Elevate both legs on pillows

Correct answer: B

Rationale: Evaluating for muscle cramping, which is a sign of electrolyte imbalance, is crucial in this scenario. Electrolyte imbalances, especially involving potassium or calcium, can lead to serious complications such as arrhythmias or seizures, which need immediate attention. Recording eating patterns (choice A) may be important for overall assessment but is not the priority in this situation. Documenting abdominal girth (choice C) and elevating legs on pillows (choice D) are not directly related to addressing the immediate concern of electrolyte imbalance and its potential complications.

2. A client has a prescription for a transcutaneous electrical nerve stimulator (TENS) unit for pain management during the postoperative period following a lumbar laminectomy. Which information should the PN reinforce about the action of the adjuvant pain modality?

• A. The discharge of electricity will distract the client's focus from the pain.
• B. An infusion of medication into the spinal canal will block pain perception.
• C. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus.
• D. A mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain.

Correct answer: D

Rationale: The TENS unit works by providing a mild electrical stimulus to the skin, which helps to 'close the gate' on pain signals, reducing the perception of pain. Choice A is incorrect because distraction is not the primary mechanism of action for TENS. Choice B is incorrect as it describes a different method of pain management involving medication infusion into the spinal canal. Choice C is incorrect as it inaccurately describes the location of pain perception modulation by the TENS unit.

3. 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.

4. The client diagnosed with HIV is taught by the nurse that the condition is transmitted through

• A. the infection passed from a mother to her baby
• B. Tears
• C. human bites
• D. insect bites

Correct answer: A

Rationale: HIV can be transmitted from a mother to her baby during childbirth or breastfeeding, making choice A the correct answer. Tears, human bites, and insect bites are not common modes of HIV transmission. While human bites can potentially transmit the virus, it is less common compared to mother-to-child transmission.

5. An older postoperative client has the nursing diagnosis 'impaired mobility related to fear of falling.' Which desired outcome best directs the PN's actions for the client?

• A. The client will ambulate with assistance every 4 hours
• B. The physical therapist will instruct the client in the use of a walker
• C. The client will use self-affirmation statements to decrease fear
• D. The PN will place a gait belt on the client prior to ambulation

Correct answer: C

Rationale: The correct answer is C. Using self-affirmation statements helps the client reduce fear and regain confidence in mobility, which is essential for improving impaired mobility. Choice A focuses more on the frequency of ambulation rather than addressing the fear of falling. Choice B involves the physical therapist and the use of a walker, which may not directly address the client's fear. Choice D is a safety measure but does not specifically target the client's fear of falling.
