Which sign might a nurse observe in a client with a high ammonia level?

Correct Answer: A

Rationale: The correct answer is A: coma. High ammonia levels can lead to hepatic encephalopathy, causing impaired brain function and potentially leading to coma. Edema (B) is typically associated with fluid retention, not high ammonia levels. Hypoxia (C) is a condition of low oxygen levels, not directly related to high ammonia levels. Polyuria (D) is excessive urination, which is not a common sign of high ammonia levels.

Correct Answer: B

Rationale: The correct answer is B because moving the wheelchair close and pivoting on the unaffected extremity is the safest way to transfer a client with hemiparesis. This method minimizes strain on the affected side and reduces the risk of falls. First, ensure the wheelchair is positioned close to the bed. Then, assist the client to pivot by placing weight on the unaffected side and using proper body mechanics. This technique maintains stability and prevents injury. Choice A is incorrect because standing and walking the client to the wheelchair puts excessive strain on the affected side, increasing the risk of falls. Choice C is incorrect as pivoting on the affected extremity can lead to injury and instability. Choice D is incorrect as having the client stand and push to the wheelchair can be dangerous and may cause further harm.

Correct Answer: A

Rationale: The correct answer is A, contusion. A contusion is a soft-tissue injury caused by blunt force resulting in bruising, without breaking the skin. This is different from the other choices. Strain (B) refers to an injury to a muscle or tendon due to overstretching. Sprain (C) is an injury to a ligament from overstretching. Dislocation (D) involves the displacement of bones at a joint, not a soft-tissue injury. Therefore, the term that specifically aligns with a soft-tissue injury from blunt force is contusion.

Correct Answer: C

Rationale: The correct answer is C: Ensure the lens is centered on the cornea. This is important because removing a hard contact lens that is not centered can cause damage to the cornea or surrounding structures. By ensuring the lens is properly positioned on the cornea before attempting removal, the risk of injury is minimized. Explanation of other choices: A: Gently irrigating the eye with solution is not the correct procedure for removing hard contact lenses as it does not address the specific task of lens removal. B: Grasping the lens with a gentle pinching motion can be harmful if the lens is not centered, leading to potential damage to the eye. D: Using sterile gloves before attempting removal is important for hygiene but does not directly affect the safe removal of hard contact lenses from an unresponsive client.

Correct Answer: B

Rationale: The correct answer is B: Vitamin B12. Strict vegetarians, especially those who exclude all animal products, are at risk of Vitamin B12 deficiency as it is primarily found in animal products. Vitamin C (A) deficiency is more common in those with poor fruit and vegetable intake. Vitamin E (C) deficiency is rare and usually seen in individuals with specific medical conditions. Magnesium (D) deficiency can occur in individuals with poor dietary intake or certain medical conditions, but it is not the primary concern for strict vegetarians.
