The polyneuropathic pattern of sensory loss suggests presence of the following syndrome:
- A. numbness & pain in distal parts of extremities
- B. numbness & analgesia in half of the body
- C. pain & sensory ataxia in half of the body
- D. analgesia & sensory ataxia in proximal parts of extremities
Correct Answer: A
Rationale: Numbness and pain in distal parts of extremities is the correct answer because polyneuropathy typically affects the longest nerves first, leading to a glove-and-stocking pattern of sensory loss. This condition is often caused by systemic diseases such as diabetes, vitamin deficiencies, or toxic exposures.
A nurse counseling a patient diagnosed with dissociative identity disorder (DID) should understand that the assessment of highest priority is:
- A. risk for self-harm
- B. cognitive functioning
- C. identification of drug abuse
- D. readiness to reestablish identity or memory
Correct Answer: A
Rationale: The correct answer is A: risk for self-harm. In patients with DID, the primary concern is ensuring their safety due to the high risk of self-harm or suicide. Assessing this risk is crucial for immediate intervention to prevent harm. Choice B, cognitive functioning, may be important but is secondary to ensuring patient safety. Choice C, identification of drug abuse, is relevant but not as urgent as addressing the risk for self-harm. Choice D, readiness to reestablish identity or memory, is important but not as critical as ensuring the patient's safety. Therefore, assessing the risk for self-harm takes precedence in the care of a patient with DID.

- C. Patient occasionally forgets to take the phenytoin until after lunch.
