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 of these types of fluid output is not typically measured?

• A. chest tube drainage
• B. emesis
• C. evaporative water from the respiratory tract
• D. urine

Correct answer: D

Rationale: The correct answer is 'urine.' Urine output is routinely measured to assess renal function and fluid balance. Choices A, B, and C are types of fluid output that are typically measured in a clinical setting. Chest tube drainage is monitored to evaluate drainage from the chest cavity, emesis refers to vomitus which can indicate gastrointestinal issues, and evaporative water from the respiratory tract is considered insensible loss and is not directly measured but estimated in overall fluid balance assessments.

3. A client with a closed chest tube drainage system accidentally disconnects the chest tube while being turned by the nurse. What should the nurse do first?

• A. Submerge the end of the chest tube in a bottle of sterile water
• B. Clamp the chest tube with a Kelly clamp
• C. Call the health care provider
• D. Instruct the client to inhale and hold his breath

Correct answer: A

Rationale: When a chest tube becomes disconnected, the priority action is to immediately reattach it to the drainage system or submerge the end in a bottle of sterile water or saline solution to reestablish a water seal. This helps prevent air from entering the pleural space and causing complications. Calling the health care provider is important but not the first action in this emergency. Instructing the client to inhale and hold his breath should be avoided as it can introduce atmospheric air into the pleural space, leading to potential issues. Clamping the chest tube is generally contraindicated, especially in cases of residual air leak or pneumothorax, as it may result in a tension pneumothorax by preventing air from escaping.

4. The LPN is receiving the report on a comatose client at the start of the shift at 1500. What statement should be of most concern?

• A. The client was repositioned on his right side at 1100.
• B. The client was bathed, and the skin was assessed head-to-toe at 0900 with no abnormal findings.
• C. The client's PEG tube was changed 6 months ago.
• D. The client's indwelling urinary catheter was last changed 5 days ago.

Correct answer: D

Rationale: When caring for a comatose client, it is crucial to monitor and maintain the integrity of the indwelling urinary catheter to prevent urinary tract infections and other complications. Changing the urinary catheter less frequently than recommended increases the risk of infection. In this scenario, the most concerning issue is the prolonged duration since the last change of the indwelling urinary catheter, which poses an immediate risk to the client's health. While repositioning every 2 hours is essential to prevent skin breakdown, the most critical aspect in this case is the catheter care. Bathing and skin assessment are important for overall hygiene and skin integrity but are not as urgent as catheter care. The timing of the PEG tube change, while relevant for care planning, is not as immediate a concern as the indwelling urinary catheter status.

5. Distribution of a drug to various tissues depends on the amount of cardiac output to each type of tissue. Which tissue would receive the highest amount of cardiac output and thus the highest amount of a drug?

• A. skin
• B. adipose tissue
• C. skeletal muscle
• D. myocardium

Correct answer: D

Rationale: The correct answer is 'myocardium.' Highly perfused tissues include vital organs like the brain, heart, kidneys, adrenal glands, and liver. The myocardium, being heart muscle, receives the highest amount of cardiac output and thus the highest amount of a drug. Choices A, B, and C are incorrect because the skin and adipose tissue are poorly perfused, while skeletal muscle is less perfused compared to vital organs like the myocardium.
