HESI LPN
HESI Fundamental Practice Exam
1. A client with chronic kidney disease is being assessed. Which laboratory value would be most concerning?
- A. Serum creatinine of 3.0 mg/dL
- B. Blood urea nitrogen (BUN) of 45 mg/dL
- C. Serum potassium of 6.5 mEq/L
- D. Hemoglobin of 10 g/dL
Correct answer: C
Rationale: In a client with chronic kidney disease, an elevated serum potassium level (hyperkalemia) is the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias due to its effect on the electrical conduction system of the heart. Monitoring and managing serum potassium levels are crucial in patients with chronic kidney disease to prevent serious complications. While elevated serum creatinine (Choice A) and Blood Urea Nitrogen (BUN) levels (Choice B) indicate impaired kidney function, hyperkalemia poses an immediate risk of cardiac complications. Hemoglobin levels (Choice D) are typically lower in chronic kidney disease due to decreased erythropoietin production, but they do not present an immediate life-threatening risk like hyperkalemia.
2. When caring for a patient diagnosed with diabetes mellitus and circulatory insufficiency, experiencing peripheral neuropathy and urinary incontinence, on which areas does the nurse focus care?
- A. Decreased pain sensation and increased risk of skin impairment
- B. Decreased caloric intake and accelerated wound healing
- C. High risk for skin infection and low saliva pH level
- D. High risk for impaired venous return and dementia
Correct answer: A
Rationale: The nurse should focus on decreased pain sensation and increased risk of skin impairment due to the patient's conditions. Peripheral neuropathy can lead to decreased pain sensation, making the patient more prone to injuries without realizing it. Additionally, the combination of circulatory insufficiency, peripheral neuropathy, and urinary incontinence can increase the risk of skin breakdown and impaired healing. Choices B, C, and D are incorrect because they do not address the specific issues related to the patient's diagnoses and symptoms.
3. A healthcare provider is assessing a client's ability to balance. Which of the following actions is appropriate when the healthcare provider conducts a Romberg test?
- A. Ask the client to extend their arms in front of their body.
- B. Ask the client to walk in a straight line heel to toe.
- C. Have the client stand with their feet together.
- D. Have the client place their hands on their hips.
Correct answer: C
Rationale: The Romberg test is a neurological test that assesses proprioception and balance. To perform this test, the client is asked to stand with their feet together and arms at their sides while closing their eyes. By removing visual input, the test challenges the vestibular and proprioceptive systems. Choices A, B, and D are incorrect because they do not align with the proper procedure for conducting the Romberg test. Extending arms in front, walking heel to toe, or placing hands on hips are not part of the Romberg test protocol and may introduce variables that could affect the assessment of balance.
4. When obtaining a urine specimen for a culture and sensitivity from an indwelling catheter, the nurse should:
- A. Cleanse the entry port prior to withdrawing urine.
- B. Use a sterile syringe to collect urine from the collection bag.
- C. Obtain the specimen from the drainage tubing.
- D. Replace the catheter before obtaining the specimen.
Correct answer: A
Rationale: The correct procedure when obtaining a urine specimen from an indwelling catheter for culture and sensitivity is to cleanse the entry port before withdrawing urine. This step helps reduce the risk of contamination and ensures the accuracy of the results. Option B is incorrect because using a sterile syringe to collect urine from the collection bag is not the recommended method for obtaining a catheter specimen. Option C is incorrect as obtaining the specimen from the drainage tubing is not the appropriate technique for collecting a urine sample from an indwelling catheter. Option D is incorrect because replacing the catheter before obtaining the specimen is not necessary and may introduce unnecessary complications.
5. A client has an order for 1000 ml of D5W over an 8-hour period. The nurse discovers that 800 ml has been infused after 4 hours. What is the priority nursing action?
- A. Ask the client if there are any breathing problems
- B. Have the client void as much as possible
- C. Check the vital signs
- D. Auscultate the lungs
Correct answer: D
Rationale: The correct answer is D: Auscultate the lungs. When a significant amount of fluid has been infused, especially in a short period, it is crucial to assess for signs of fluid overload or pulmonary complications, such as crackles or decreased breath sounds. This can be achieved by auscultating the lungs. Choice A, asking the client about breathing problems, may provide valuable information, but direct assessment through auscultation takes priority. Choice B, having the client void, and Choice C, checking vital signs, are important nursing actions but are not as urgent as assessing the lungs for potential complications in this scenario.
