HESI LPN
Practice HESI Fundamentals Exam
1. A client with chronic kidney disease is experiencing hyperkalemia. Which medication should the LPN/LVN anticipate being prescribed to lower the client's potassium level?
- A. Furosemide (Lasix)
- B. Sodium polystyrene sulfonate (Kayexalate)
- C. Calcium gluconate
- D. Albuterol (Proventil)
Correct answer: B
Rationale: The correct answer is B: Sodium polystyrene sulfonate (Kayexalate). Kayexalate is commonly used to lower potassium levels in clients with hyperkalemia by exchanging sodium ions for potassium ions in the large intestine, leading to the elimination of excess potassium from the body. Choice A, Furosemide (Lasix), is a loop diuretic that helps with fluid retention but does not directly lower potassium levels. Choice C, Calcium gluconate, is used to treat calcium deficiencies and does not impact potassium levels. Choice D, Albuterol (Proventil), is a bronchodilator used to treat respiratory conditions and does not affect potassium levels. Therefore, the LPN/LVN should anticipate the prescription of Kayexalate to address the client's hyperkalemia.
2. A client with HIV/AIDS is receiving zidovudine (Retrovir). The nurse should monitor the client for which of the following adverse effects?
- A. Hyperglycemia
- B. Anemia
- C. Hypertension
- D. Hypercalcemia
Correct answer: B
Rationale: The correct answer is B: Anemia. Zidovudine (Retrovir) can cause bone marrow suppression, leading to anemia. Monitoring for signs of anemia, such as fatigue, pallor, and shortness of breath, is crucial. Choice A, Hyperglycemia, is not a common adverse effect of zidovudine. Choice C, Hypertension, is not directly associated with zidovudine use. Choice D, Hypercalcemia, is also not a typical adverse effect of zidovudine.
3. The following statements pertain to devolution as mandated by the local government code. Which of these is not correct?
- A. People can participate in policymaking relative to healthcare delivery.
- B. Devolution will enhance the quality of community life.
- C. The barangay shall set criteria as to who shall be given priority in the delivery of healthcare services.
- D. The DOH shall transfer regulatory function of inspecting food establishments to local government units.
Correct answer: D
Rationale: The correct answer is D. The Department of Health (DOH) retains regulatory functions for inspecting food establishments, and it is not transferred to local government units. Choices A, B, and C are correct because devolution allows people to participate in policymaking for healthcare, enhances community life quality, and empowers the barangay to set criteria for healthcare service prioritization.
4. A client reports new onset hearing loss bilaterally after taking a medication with known ototoxic effects. Which type of hearing loss should the nurse suspect?
- A. Conductive
- B. Sensorineural
- C. Mixed
- D. Central
Correct answer: B
Rationale: The correct answer is B: Sensorineural. Ototoxic medications can lead to sensorineural hearing loss by affecting the inner ear or auditory nerve. Conductive hearing loss is related to issues in the middle or outer ear, not typically caused by ototoxic medications. Mixed hearing loss is a combination of conductive and sensorineural components. Central hearing loss is related to the central nervous system, not commonly caused by ototoxic medications. Therefore, in this case, the nurse should suspect sensorineural hearing loss.
5. What is the primary focus of postoperative nursing care for the client with colon trauma?
- A. Monitoring for elevated coagulation studies
- B. Observation for and prevention of fistulas
- C. Monitoring for signs of hyponatremia
- D. Observation for and prevention of infection
Correct answer: D
Rationale: The correct answer is D: Observation for and prevention of infection. Postoperative nursing care for a client with colon trauma primarily focuses on preventing infections. Clients with colon trauma are at high risk for infections due to the disruption of the intestinal barrier. Monitoring for signs of infection, maintaining proper wound care, administering antibiotics as prescribed, and implementing strict aseptic techniques are essential in preventing postoperative infections. Choices A, B, and C are incorrect because elevated coagulation studies, fistulas, and hyponatremia are not the primary concerns in the immediate postoperative period for a client with colon trauma.
