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. The client with gastroesophageal reflux disease (GERD) is receiving dietary modification education from the nurse. Which statement by the client indicates a need for further teaching?
- A. I will avoid eating large meals before bedtime.
- B. I will limit coffee consumption to the morning hours.
- C. I will elevate the head of my bed while sleeping.
- D. I will avoid spicy and acidic foods.
Correct answer: B
Rationale: The correct answer is B. Clients with GERD should avoid coffee as it can relax the lower esophageal sphincter and exacerbate symptoms. Limiting coffee consumption to the morning hours may not be sufficient, as coffee can still contribute to GERD symptoms throughout the day. Choices A, C, and D are all appropriate strategies for managing GERD symptoms. Avoiding large meals before bedtime, elevating the head of the bed while sleeping, and steering clear of spicy and acidic foods are all recommended practices to help alleviate GERD symptoms. Therefore, the client's statement in option B indicates a need for further teaching to completely address dietary modifications for managing GERD.
3. The nurse is preparing to administer a subcutaneous injection of insulin to a client with diabetes. What is the best site for the nurse to select for this injection?
- A. Ventrogluteal site
- B. Dorsogluteal site
- C. Deltoid site
- D. Abdomen
Correct answer: D
Rationale: The correct answer is 'D: Abdomen.' The abdomen is the best site for insulin injections as it provides a larger area with consistent absorption rates due to the high vascularity of the area. The subcutaneous tissue in the abdomen allows for a more predictable and consistent absorption of insulin compared to other sites. Ventrogluteal and dorsogluteal sites are not commonly used for insulin injections due to the risk of hitting the sciatic nerve or causing tissue damage. The deltoid site is more commonly used for intramuscular injections rather than subcutaneous injections like insulin.
4. When assessing the skin of an immobilized patient, what should the nurse do?
- A. Assess the skin every 4 hours.
- B. Limit the amount of fluid intake.
- C. Use a standardized tool such as the Braden Scale.
- D. Have special times for inspection to not interrupt routine care.
Correct answer: C
Rationale: When assessing the skin of an immobilized patient, it is essential to use a standardized tool like the Braden Scale. This tool helps in systematically evaluating the patient's risk of developing pressure ulcers. Assessing the skin every 4 hours (Choice A) may be too frequent or unnecessary unless there are specific concerns or orders. Limiting fluid intake (Choice B) is not directly related to skin assessment in an immobilized patient. Having special times for inspection to avoid interrupting routine care (Choice D) is not as crucial as using a standardized tool for consistent and comprehensive skin assessment.
5. A healthcare professional is preparing to administer metoprolol 200 mg PO daily. The medication available is metoprolol 100 mg/tablet. How many tablets should the healthcare professional administer? (Round the answer to the nearest whole number. Do not use a trailing zero.)
- A. 1 tablet
- B. 2 tablets
- C. 0.5 tablet
- D. 4 tablets
Correct answer: B
Rationale: To administer 200 mg of metoprolol using 100 mg tablets, the healthcare professional should give 2 tablets. Each tablet contains 100 mg of metoprolol, so 2 tablets will provide the required 200 mg dose. Choice A is incorrect because 1 tablet would only provide 100 mg, which is insufficient. Choice C is incorrect as fractions of tablets are usually not used in practice to ensure accurate dosing. Choice D is incorrect as it would result in an overdose, providing 400 mg instead of the prescribed 200 mg.
