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-Séquard syndrome
• B. posterior cord syndrome
• C. central cord syndrome
• D. cauda equina syndrome

Correct answer: A

Rationale: Brown-Séquard 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. Which action exemplifies the use of evidence-based practice in the delivery of client care?

• A. Advising a client to agree to the treatment recommended by their healthcare provider
• B. Taking a rectal temperature from a client for whom bleeding precautions have been instituted
• C. Donning sterile gloves to change an abdominal wound dressing
• D. Encouraging a client to take an herbal substance to treat their insomnia

Correct answer: C

Rationale: Evidence-based practice is an approach to client care where the nurse integrates the client’s preferences, clinical expertise, and the best research evidence to deliver quality care. Donning sterile gloves to change an abdominal wound dressing exemplifies evidence-based practice as it prevents the entrance of harmful bacteria into the wound, following best practice guidelines. The other options do not align with evidence-based practice. Advising a client to agree to a treatment does not involve integrating research evidence. Taking herbal substances may not be supported by strong research evidence and can pose risks. Additionally, rectal temperature-taking in a client with bleeding precautions can increase the risk of injury to the rectal mucosa, not aligning with best practices in care delivery.

3. What type of injury is associated with acute hyphema?

• A. orthopedic
• B. eye
• C. insect sting or snakebite
• D. gynecological trauma

Correct answer: B

Rationale: Acute hyphema is associated with an eye injury, typically resulting from blunt trauma. The presence of blood in the anterior chamber of the eye causes a half-moon appearance or a horizontal line across the globe when the client is upright. Choices A, C, and D are incorrect because acute hyphema is not related to orthopedic injuries, insect stings, snakebites, or gynecological trauma.

4. Which of the following neurological disorders is characterized by writhing, twisting movements of the face and limbs?

• A. epilepsy
• B. Parkinson's
• C. multiple sclerosis
• D. Huntington's chorea

Correct answer: D

Rationale: Huntington's chorea is a neurological disorder characterized by writhing, twisting movements of the face and limbs, known as chorea. Epilepsy is characterized by seizures, not writhing, twisting movements. Parkinson's disease presents with tremors, rigidity, and bradykinesia, not writhing, twisting movements. Multiple sclerosis affects the central nervous system but does not typically involve writhing, twisting movements. Therefore, the correct answer is Huntington's chorea as it specifically manifests with these characteristic movements.

5. A client is told that his test is positive, but in fact, the client does not have the disease tested for. Which type of false report is this an example of?

• A. positive
• B. false positive
• C. negative
• D. false negative

Correct answer: B

Rationale: The correct answer is 'false positive.' A false-positive result occurs when a test result is labeled positive in error, when the actual result is negative. In this scenario, the client received a positive test result incorrectly, as he does not have the disease being tested for. Choice A ('positive') is too vague and does not specify that the result was incorrect. Choice C ('negative') is the opposite of what happened in the scenario. Choice D ('false negative') refers to a situation where a test result is labeled negative incorrectly, which is not the case in this scenario.
