Medical Surgical HESI

Correct Answer: D

Rationale: The correct answer is D: Compression of a nerve. In carpal tunnel syndrome, pain arises from the compression of the median nerve within the carpal tunnel. This compression leads to symptoms such as pain, numbness, and tingling in the hand and arm. Choices A, B, and C are incorrect because carpal tunnel syndrome pain is primarily caused by the physical compression of the nerve, rather than irritation of nerve endings, diminished blood flow, or ischemic tissue changes.

Correct Answer: B

Rationale: The ABG results show a low pH (acidosis) and increased pCO2, indicating respiratory acidosis. In respiratory acidosis, the lungs cannot remove enough CO2, leading to its accumulation in the blood. This often occurs in conditions like COPD and is consistent with the patient's smoking history. Metabolic acidosis (choice A) is characterized by low pH and low HCO3 levels. Metabolic alkalosis (choice C) is marked by high pH and high HCO3 levels. Respiratory alkalosis (choice D) presents with high pH and low pCO2.

Correct Answer: B

Rationale: The correct answer is B: Oranges. Oranges are not a rich source of iron. Iron-rich foods include liver, leafy green vegetables, and kidney beans. Oranges are a good source of vitamin C but are not high in iron. Therefore, if the client selects oranges as an iron-rich food, it indicates a need for additional instructions on choosing foods high in iron.

Correct Answer: B

Rationale: The correct answer is B: Risk for falls. In a postoperative client with hypovolemic shock, the most crucial problem to address is the risk for falls. Hypovolemic shock can result in dizziness and weakness, making the client prone to falling. Preventing falls is essential to avoid further injury or complications. Choices A, C, and D are not the top priority in this scenario. While infection, impaired skin integrity, and activity intolerance are important concerns, preventing falls takes precedence due to the immediate risk of injury associated with hypovolemic shock.

Correct Answer: B

Rationale: The correct answer is to speak to the client each time the nurse enters the room. This intervention is crucial for orienting and reassuring the client, promoting safety, and facilitating communication. Keeping the room well-lit (Choice A) can be helpful but is not as essential as direct verbal communication. Ensuring the client wears glasses (Choice C) may not be feasible or necessary for someone who is legally blind. Providing written instructions in large print (Choice D) is not effective for a client with visual impairments.
