HESI Fundamentals Practice Test

Correct Answer: B

Rationale: The most critical reason for initiating intravenous infusions in the upper extremities of adults is to reduce the risk of thrombosis (B). Venous return is typically better in the upper extremities, decreasing the likelihood of thrombus formation, which could be life-threatening if dislodged. Although superficial veins are easily found in the feet and ankles (A), this is not the primary reason for choosing the upper extremities. Handling a leg or foot with an IV (C) is not significantly more challenging than handling an arm or hand. The depth of veins in the feet and ankles (D) does not primarily determine the site for IV placement.

Correct Answer: B

Rationale: When caring for an immobile client, the nursing diagnosis with the highest priority is impaired gas exchange. This is because impaired gas exchange implies difficulty with breathing, which is essential for sustaining life. Adequate oxygenation is crucial for all bodily functions, and any impairment in gas exchange can lead to serious complications, making it the priority nursing diagnosis to address in an immobile client. Choices A, C, and D are important considerations as well when caring for an immobile client, but they are secondary to impaired gas exchange. Risk for fluid volume deficit may occur due to immobility, but ensuring proper gas exchange takes precedence as it directly impacts the client's immediate survival. Risk for impaired skin integrity is a concern in immobile clients but does not pose an immediate threat to life like impaired gas exchange. Altered tissue perfusion is also critical but is usually a consequence of impaired gas exchange, reinforcing the priority of addressing gas exchange first.

Correct Answer: A

Rationale: Increased oxygen saturation (A) is the most direct indicator of the effectiveness of albuterol (Proventil) in improving breathing. Oxygen saturation reflects the amount of oxygen in the blood, showing that the albuterol is helping with air exchange in the lungs. While decreased respiratory rate (B), absence of audible wheezing (C), and improved exercise tolerance (D) are positive outcomes, they are secondary to oxygen saturation. Oxygen saturation directly reflects the improvement in the client's respiratory status and the effectiveness of the medication.

Correct Answer: A

Rationale: The first intervention should be to check the drainage tubing for a kink. This step is crucial as any kinks in the tubing could obstruct urine flow, leading to a decreased output. By ensuring the tubing is free from any obstructions, the healthcare provider can address a potential mechanical issue causing the low output before considering other interventions. Reviewing the intake and output record may provide valuable information but should come after ensuring the tubing is clear. Notifying the healthcare provider can be done later if needed, but the immediate concern is to check for any obstructions. Giving the client water to drink may be necessary depending on the assessment findings, but addressing a possible kink in the tubing takes precedence.

Correct Answer: B

Rationale: The finding of obtaining 200 cc of urine after catheterization indicates urinary retention, as the bladder did not empty completely after the first void. This situation may require further assessment and intervention to address the issue of incomplete bladder emptying. Choice A is incorrect because voiding normally would indicate a larger amount of urine output. Choice C is incorrect as renal failure would typically present with other signs and symptoms. Choice D is incorrect as the presence of urinary retention does not necessarily mean the need for an indwelling catheter immediately.
