HESI PN Exit Exam 2024

HESI LPN

1. Before administering an antibiotic that can cause nephrotoxicity, which lab value is most important for the nurse to review?

A. Hemoglobin and Hematocrit
B. Serum Calcium
C. Serum Creatinine
D. WBC

Correct answer: C

Rationale: The correct answer is C: Serum Creatinine. Serum creatinine is a key indicator of kidney function. Reviewing this value is crucial as it helps assess the client's risk for nephrotoxicity before administering the antibiotic. Elevated serum creatinine levels can indicate impaired kidney function, which would increase the risk of nephrotoxicity. Choices A, B, and D are not as directly related to kidney function and nephrotoxicity. Hemoglobin and hematocrit levels assess for anemia, serum calcium levels monitor calcium balance, and WBC count evaluates for infections. While these values are important for overall patient assessment, they are not as specific to assessing nephrotoxicity risk as serum creatinine.

2. When teaching a patient with diabetes about foot care, which of the following should the nurse emphasize?

A. Avoid soaking feet daily to prevent dryness and skin breakdown
B. Select well-fitting shoes to prevent injury
C. Trim toenails straight across and file the edges
D. Avoid using heating pads to prevent burns

Correct answer: C

Rationale: The correct answer is C. Trimming toenails straight across and filing the edges is crucial in diabetic foot care to prevent ingrown toenails and foot injuries. Soaking feet daily can lead to dryness and skin breakdown, increasing the risk of infection. Selecting well-fitting shoes is important to prevent pressure points and skin damage, not tight-fitting shoes. Using heating pads can result in burns or injuries due to decreased sensation in diabetic feet, so it's essential to avoid them.

3. Which condition is most commonly associated with a "bull's eye" rash?

A. Lyme disease
B. Rocky Mountain spotted fever
C. Syphilis
D. Toxoplasmosis

Correct answer: A

Rationale: The correct answer is A: Lyme disease. The "bull's eye" rash, or erythema migrans, is a hallmark of early Lyme disease, caused by the bacterium Borrelia burgdorferi. Choice B, Rocky Mountain spotted fever, presents with a different type of rash. Choice C, Syphilis, typically presents with a painless ulcer and rash but not a "bull's eye" rash. Choice D, Toxoplasmosis, does not typically present with a "bull's eye" rash.

4. Which nursing intervention is most appropriate for managing delirium in an elderly patient?

A. Keeping the room brightly lit
B. Administering sedatives as needed
C. Encouraging family presence
D. Restricting fluids

Correct answer: C

Rationale: Encouraging family presence is the most appropriate intervention for managing delirium in elderly patients. This intervention provides orientation, reassurance, and comfort, which can help reduce confusion and anxiety, thus aiding in managing delirium. Keeping the room brightly lit (Choice A) may worsen delirium as it can disrupt the patient's sleep-wake cycle. Administering sedatives (Choice B) should be avoided unless absolutely necessary due to the risk of worsening delirium. Restricting fluids (Choice D) is not a recommended intervention for managing delirium, as hydration is important for overall patient well-being.

5. A client is post-operative day one following a colostomy surgery. The nurse notices the stoma is dark purple. What is the most appropriate action?

A. Document the finding and continue to monitor.
B. Apply warm compresses to the stoma.
C. Notify the healthcare provider immediately.
D. Encourage the client to ambulate.

Correct answer: C

Rationale: A dark purple stoma may indicate compromised blood flow to the stoma, which is an emergency. Immediate notification of the healthcare provider is necessary to prevent further complications. Simply documenting and monitoring the finding (Choice A) could lead to delays in addressing a potentially serious issue. Applying warm compresses to the stoma (Choice B) may not address the underlying cause of the dark purple color. Encouraging the client to ambulate (Choice D) is not the priority when a compromised blood flow to the stoma is suspected.
