HESI LPN
Practice HESI Fundamentals Exam
1. A client requires a 24-hour urine collection. Which statement by the client indicates an understanding of the teaching?
- A. "I had a bowel movement, but I was able to save the urine."
- B. "I have a specimen in the bathroom from about 30 minutes ago."
- C. "I flushed what I urinated at 7 a.m. and have saved all urine since."
- D. "I drink a lot, so I will fill up the bottle and complete the test quickly."
Correct answer: C
Rationale: The correct answer is C because for a 24-hour urine collection, the first void is discarded, and all subsequent urine should be saved. Choice A is incorrect because bowel movements do not contribute to a urine collection. Choice B indicates a single specimen rather than continuous collection over 24 hours. Choice D is incorrect as it incorrectly suggests rushing the test by drinking excessively.
2. A client has a new prescription for nitroglycerin sublingual tablets. Which of the following instructions should the nurse include?
- A. Take the medication with food.
- B. Place the tablet under your tongue and let it dissolve completely.
- C. Swallow the tablet whole with a glass of water.
- D. Chew the tablet for faster relief.
Correct answer: B
Rationale: The correct instruction for a client prescribed nitroglycerin sublingual tablets is to place the tablet under the tongue and let it dissolve completely. This route of administration allows for rapid absorption of the medication through the oral mucosa, providing quick relief for angina symptoms. Option A, taking the medication with food, is incorrect as nitroglycerin should be taken sublingually, not with food. Option C, swallowing the tablet whole with water, is incorrect as sublingual tablets should not be swallowed whole. Option D, chewing the tablet for faster relief, is also incorrect as chewing the tablet can lead to rapid absorption and potential adverse effects rather than a controlled release for angina relief.
3. During a skin assessment, a healthcare professional is observing a group of clients. Which of the following lesions should the healthcare professional identify as vesicles?
- A. Acne
- B. Warts
- C. Psoriasis
- D. Herpes simplex
Correct answer: D
Rationale: Vesicles are small fluid-filled blisters. Herpes simplex is an example of a vesicular lesion, characterized by small, fluid-filled blisters. Acne presents as comedones, papules, pustules, or nodules, not vesicles. Warts are caused by the human papillomavirus and appear as rough, raised growths. Psoriasis is a chronic autoimmune condition that results in red, scaly patches on the skin, not vesicles.
4. A client with chronic kidney disease is being assessed. Which of the following laboratory values would be most concerning?
- A. Serum creatinine of 3.0 mg/dL
- B. Serum potassium of 6.5 mEq/L
- C. Blood urea nitrogen (BUN) of 45 mg/dL
- D. Hemoglobin of 10 g/dL
Correct answer: B
Rationale: In a client with chronic kidney disease, elevated serum potassium levels (hyperkalemia) are the most concerning finding. Hyperkalemia can lead to life-threatening cardiac dysrhythmias. Monitoring and managing serum potassium levels are crucial in patients with kidney disease to prevent severe complications. While elevated creatinine (Choice A) and BUN (Choice C) are indicative of impaired kidney function, hyperkalemia poses a more immediate threat to the client's health. Hemoglobin levels (Choice D) can be affected by chronic kidney disease but are not as acutely dangerous as severe hyperkalemia.
5. A client has a new prescription for parenteral nutrition (PN) in 20% dextrose and fat emulsions. Which of the following is an appropriate action to include in the plan of care?
- A. Monitor blood glucose levels daily.
- B. Change the PN infusion bag every 24 hours.
- C. Prepare the client for a central venous line.
- D. Administer the PN and fat emulsion together.
Correct answer: C
Rationale: When a client requires parenteral nutrition (PN) with a high dextrose concentration, such as 20%, it typically has a high osmolarity. High osmolarity solutions should be infused through a central venous line to prevent peripheral vein irritation and potential complications. Therefore, preparing the client for a central venous line is essential for the safe administration of PN with high dextrose. Monitoring blood glucose levels daily is important but not directly related to the need for a central venous line. Changing the PN infusion bag every 24 hours helps prevent bacterial contamination, but it is not the most critical action in this scenario. Administering the PN and fat emulsion together or separately is a matter of compatibility and administration guidelines, but it is not the key concern in this situation.
