HESI LPN
Practice HESI Fundamentals Exam Questions
Question 1 of 5
A client with type 1 diabetes mellitus is experiencing hypoglycemia. What is the best initial action for the LPN/LVN to take?
Correct Answer: B
Rationale: The best initial action for a client with type 1 diabetes mellitus experiencing hypoglycemia is to give them 4 ounces of orange juice. Orange juice quickly raises blood glucose levels in a hypoglycemic client. Administering glucagon intramuscularly is not the best initial action for hypoglycemia; it is usually reserved for severe hypoglycemia cases. Giving a snack containing protein and carbohydrates is not as rapid as orange juice in raising blood glucose levels during hypoglycemia. Encouraging the client to rest until symptoms resolve does not address the immediate need to raise blood glucose levels in a hypoglycemic state.
Question 2 of 5
A client with diabetes mellitus is experiencing polyuria, polydipsia, and polyphagia. What is the most important action for the LPN/LVN to take?
Correct Answer: B
Rationale: The correct answer is to monitor the client's blood glucose level. When a client with diabetes mellitus presents with symptoms of polyuria, polydipsia, and polyphagia, it indicates hyperglycemia. Monitoring blood glucose levels is crucial to assess and manage the client's condition effectively. Option A, encouraging the client to increase fluid intake, may exacerbate polyuria. Option C, administering insulin, should be done based on the healthcare provider's prescription after assessing the blood glucose level. Option D, assessing the client's urine output, is important but not the most immediate action needed in this scenario; monitoring blood glucose levels takes precedence.
Question 3 of 5
A client with chronic kidney disease is receiving epoetin alfa (Epogen). Which laboratory value should the LPN/LVN monitor to determine the effectiveness of this medication?
Correct Answer: B
Rationale: The correct answer is B: Hemoglobin. Monitoring hemoglobin levels is essential to assess the effectiveness of epoetin alfa in clients with chronic kidney disease. Epoetin alfa is a medication that stimulates red blood cell production, aiming to increase hemoglobin levels and improve symptoms of anemia in these patients. Monitoring serum potassium (Choice A) is important in clients with kidney disease, but it is more related to assessing electrolyte balance rather than the direct effectiveness of epoetin alfa. Serum creatinine (Choice C) and blood urea nitrogen (Choice D) are kidney function tests that help evaluate kidney health but do not specifically reflect the effectiveness of epoetin alfa therapy.
Question 4 of 5
A client with diabetes mellitus is being taught by a nurse about mixing regular and NPH insulin. Which of the following statements by the client indicates an understanding of the teaching?
Correct Answer: A
Rationale: The correct answer is A. Rolling the NPH vial between the hands before drawing it up ensures proper mixing of the insulin. Choice B is incorrect because regular insulin should be drawn up first to avoid contamination. Choice C is incorrect as injecting air into the vial of regular insulin is not necessary. Choice D is incorrect as there is no need to wait 10 minutes after mixing the insulin before injecting it.
Question 5 of 5
A client has an indwelling urinary catheter. Which of the following actions should the nurse take to prevent infection?
Correct Answer: B
Rationale: Cleaning the perineal area with antiseptic solution daily is essential to prevent infection when caring for a client with an indwelling urinary catheter. This practice helps reduce the risk of introducing pathogens into the urinary tract. Ensuring the catheter tubing is free of kinks (Choice A) is important for maintaining proper urine flow but is not directly related to preventing infection. Irrigating the catheter with normal saline every shift (Choice C) is not a routine practice and can increase the risk of introducing pathogens. Securing the catheter to the client's leg (Choice D) is important for stability but does not directly prevent infection.
