Practice HESI Fundamentals Exam
1. 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?
- A. I should roll the NPH vial between my hands before drawing it up.
- B. I should draw up the NPH insulin before the regular insulin.
- C. I should inject air into the vial of regular insulin first.
- D. I should wait 10 minutes after mixing the insulin to inject it.
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.
2. Following surgery on the neck, the client asks the LPN why the head of the bed is up so high. The LPN should tell the client that the high-Fowler position is preferred for what reason?
- A. To reduce strain on the incision
- B. To promote drainage of the wound
- C. To provide stimulation for the client
- D. To reduce edema at the operative site
Correct answer: D
Rationale: The high-Fowler position is preferred after neck surgery to reduce edema at the operative site. Elevating the head of the bed promotes venous return and drainage, aiding in decreasing swelling and fluid accumulation, which helps reduce edema at the operative site. Choice A is incorrect as the main purpose is not solely about reducing strain on the incision. Choice B is incorrect because while drainage may occur, it is not the primary reason for maintaining the high-Fowler position. Choice C is incorrect as providing stimulation is not the primary rationale for positioning the client in high-Fowler.
3. The patient refuses to bathe in the morning, stating a preference for evening baths. What is the best action for the nurse?
- A. Defer the bath until evening and pass on the information to the next shift.
- B. Tell the patient that daily morning baths are part of the 'normal' routine.
- C. Explain the importance of maintaining morning hygiene practices.
- D. Cancel hygiene for the day and attempt again in the morning.
Correct answer: A
Rationale: The best action by the nurse is to respect the patient's preference and autonomy. Defer the bath until evening to allow the patient to follow their usual hygiene routine. Passing on the information to the next shift ensures continuity of care. Choice B is incorrect because it disregards the patient's preference and autonomy. Choice C, while important, does not address the patient's immediate concern. Choice D is incorrect as it does not respect the patient's wishes and may lead to further resistance to bathing.
4. A nurse at a provider’s office is discussing routine screenings with a 45-year-old female client who has no specific family history of cancer or diabetes mellitus. Which of the following client statements indicates that the client understands how to proceed?
- A. “So I don’t need the colon cancer screening for another 2 or 3 years.”
- B. “For now, I should continue to have a mammogram each year.”
- C. “Because the doctor just performed a Pap smear, I’ll return next year for another one.”
- D. “I had my glucose test last year, so I won’t need it again for 4 years.”
Correct answer: B
Rationale: The correct answer is B. Mammograms are recommended annually for women starting at age 40 or 45. This statement aligns with current guidelines for breast cancer screening in women without specific risk factors. Choice A is incorrect because colon cancer screenings are typically recommended at different intervals. Choice C is incorrect as Pap smears are usually done every 3-5 years based on age and risk factors. Choice D is incorrect because glucose testing is usually recommended more frequently, especially for individuals at risk for diabetes mellitus.
5. A client is being treated for diabetic ketoacidosis (DKA). Which laboratory value would be most concerning?
- A. Blood glucose of 350 mg/dL
- B. Serum bicarbonate of 18 mEq/L
- C. Arterial pH of 7.20
- D. Serum potassium of 5.5 mEq/L
Correct answer: C
Rationale: In a client with diabetic ketoacidosis (DKA), the most concerning laboratory value is an arterial pH of 7.20. An arterial pH of 7.20 indicates severe acidosis, which is a critical condition requiring immediate intervention. This pH level reflects a significant imbalance in the body's acid-base status, potentially leading to serious complications. High blood glucose levels (choice A) are expected in DKA but do not directly indicate the severity of acidosis. A serum bicarbonate level of 18 mEq/L (choice B) is low but not as immediately critical as a pH of 7.20. Serum potassium of 5.5 mEq/L (choice D) is elevated, which can occur in DKA due to insulin deficiency, but it is not the most concerning value in this scenario.
