HESI Medical Surgical Specialty Exam

Correct Answer: D

Rationale: In the oliguric phase of acute kidney injury (AKI), clients may require tube feedings with kidney-specific formulas. These formulations are lower in sodium and potassium, which are crucial considerations due to impaired kidney function. Higher phosphorus content is not a feature of kidney-specific formulations for AKI. Therefore, options A and B (lower sodium and lower potassium) should be discussed in the teaching plan. Option C, higher phosphorus, is incorrect as kidney-specific formulas are not intended to be higher in phosphorus content for AKI patients.

Correct Answer: C

Rationale: A pale or cyanotic appearance of the ileostomy stoma indicates compromised circulation, which can lead to necrosis if not promptly addressed. On the other hand, blood-tinged urine and serous sanguineous drainage are common following a complete cystectomy with ileal conduit. These findings do not typically indicate an urgent issue. An oxygen saturation of 92% on room air is slightly below the normal range but does not warrant urgent healthcare provider contact unless accompanied by significant respiratory distress or other concerning symptoms.

Correct Answer: A

Rationale: Clients who take synthetic creatine supplements, metformin, and high-dose or long-term NSAIDs are at risk for kidney dysfunction. Synthetic creatine supplements can cause kidney damage, metformin may rarely cause lactic acidosis leading to renal impairment, and high-dose NSAIDs can lead to acute kidney injury. Prenatal vitamins and albuterol nebulizers are not known to significantly impact kidney function, thus do not pose a risk for kidney problems.

Correct Answer: C

Rationale: When an ELISA test for HIV is positive, it is essential to confirm the result with a Western blot. The Western blot is the confirmatory test for HIV. Choice A is incorrect because a positive ELISA test does not confirm HIV infection. Choice B is incorrect as it assumes a different diagnosis. Choice D is incorrect because a positive ELISA test does indicate potential HIV infection and requires confirmation.

Correct Answer: B

Rationale: Increasing the oxygen flow rate beyond 2 L/min for a client with COPD can decrease the client's oxygen-based respiratory drive. In clients with COPD, the natural respiratory drive is based on the level of oxygen instead of carbon dioxide, as seen in healthy individuals. Increasing the oxygen level independently can suppress the drive to breathe, leading to respiratory failure. Choices A, C, and D are incorrect because drying of nasal passages, increased risk of pneumonia due to drier air passages, and decreasing the carbon dioxide-based respiratory drive are not the primary concerns associated with increasing the oxygen flow rate in a client with COPD.
