1. Which of the following syndromes associated with incomplete lesions of the spinal cord results from damage to one-half of the spinal cord?

• A. Brown-S�quard syndrome
• B. posterior cord syndrome
• C. central cord syndrome
• D. cauda equina syndrome

Correct answer: A

Rationale: Brown-S�quard syndrome is indeed associated with incomplete lesions of the spinal cord, and it specifically results from damage to one-half of the spinal cord. This syndrome manifests as ipsilateral motor paralysis, ipsilateral loss of vibration and proprioception, and contralateral loss of pain and temperature sensation. Posterior cord syndrome mainly involves the loss of proprioception and vibratory sense, while sparing motor function and pain sensation. Central cord syndrome typically presents with more weakness in the upper extremities compared to the lower extremities due to central spinal cord damage. Cauda equina syndrome affects the nerve roots at the level of the conus medullaris, leading to symptoms like lower extremity weakness, numbness, and bowel/bladder dysfunction.

2. While repositioning a comatose client, the nurse senses a tingling sensation as she lowers the bed. What action should she take?

• A. Unplug the bed's power source.
• B. Remove the client from the bed immediately.
• C. Notify the biomedical department at once.
• D. Turn off the oxygen.

Correct answer: A

Rationale: The correct action for the nurse to take when sensing a tingling sensation while lowering the bed with a comatose client is to unplug the bed's power source. This should be the initial step as there may be a fault in the bed's grounding. Removing the client from the bed immediately is not safe until the electrical issue is resolved. Notifying the biomedical department is important but should come after ensuring the immediate safety of the client. Turning off the oxygen is not necessary unless there is a specific issue related to oxygen delivery, which is not indicated in this scenario.

3. The healthcare provider sustains a needle puncture that requires HIV prophylaxis. Which of the following medication regimens should be used?

• A. an antibiotic such as Metronidazole and a protease inhibitor (Saquinavir)
• B. two non-nucleoside reverse transcriptase inhibitors
• C. one protease inhibitor such as Nelfinavir
• D. two protease inhibitors

Correct answer: B

Rationale: In the scenario of a needle puncture requiring HIV prophylaxis, the CDC recommends initiating treatment with two non-nucleoside reverse transcriptase inhibitors, unless there is drug resistance. This regimen is preferred over other options such as a single protease inhibitor or two protease inhibitors due to its effectiveness and safety profile in this specific context. Non-nucleoside reverse transcriptase inhibitors are commonly used in post-exposure prophylaxis due to their activity against HIV and lower risk of resistance development compared to other antiretroviral drug classes.

4. The client is unsure about making medical decisions as their disease progresses and wants to appoint someone to make these decisions. Which of the following options would be most appropriate?

• A. a living will
• B. informed consent
• C. a healthcare proxy
• D. non-informed consent

Correct answer: C

Rationale: The correct answer is 'a healthcare proxy.' A healthcare proxy involves the client appointing an individual to make medical decisions on their behalf if they become unable to do so. This option allows the client to choose someone they trust to act in their best interests. Choice A, 'a living will,' is a legal document that outlines a person's wishes regarding medical treatment in case they are unable to communicate their decisions. While it is important, it does not involve appointing someone to make decisions. Choice B, 'informed consent,' is a process where a healthcare provider explains a treatment or procedure, including its risks and benefits, to a patient who can then decide whether to proceed. This is not about appointing someone to make decisions on the patient's behalf. Choice D, 'non-informed consent,' is not a valid concept in healthcare. Informed consent is crucial for respecting a patient's autonomy and decision-making capacity.

5. Which is the proper hand position for performing chest percussion?

• A. Use the side of the hands
• B. Flatten the hands
• C. Spread the fingers of both hands
• D. Cup the hands

Correct answer: D

Rationale: The proper hand position for performing chest percussion is to cup the hands. Cupping the hands helps produce a vibration that aids in loosening respiratory secretions effectively. This technique is essential for therapeutic chest physiotherapy. Using the side of the hands, flattening the hands, or spreading the fingers of both hands do not generate the necessary vibration required for chest percussion. These hand positions are not considered proper techniques in this context and may not provide the desired therapeutic effect.
