HESI Fundamentals Practice Test
1. The healthcare professional observes a UAP taking a client's blood pressure in the lower extremity. Which observation of this procedure requires the healthcare professional's intervention?
- A. The cuff wraps around the girth of the leg.
- B. The UAP auscultates the popliteal pulse with the cuff on the lower leg.
- C. The client is placed in a prone position.
- D. The systolic reading is 20 mm Hg higher than the blood pressure in the client's arm.
Correct answer: B
Rationale: When obtaining blood pressure in the lower extremities, the popliteal pulse is the site for auscultation when the blood pressure cuff is applied around the thigh. Auscultating the popliteal pulse with the cuff on the lower leg is incorrect as it may lead to an inaccurate reading. Placing the client in a prone position and wrapping the cuff around the girth of the leg are acceptable practices. A systolic reading that is 20 mm Hg higher in the lower extremity compared to the arm is expected due to the difference in blood pressure between the upper and lower parts of the body.
2. The healthcare provider assesses a 2-year-old who is admitted for dehydration and finds that the peripheral IV rate by gravity has slowed, even though the venous access site is healthy. What should the healthcare provider do next?
- A. Apply a warm compress proximal to the site.
- B. Check for kinks in the tubing and raise the IV pole.
- C. Adjust the tape that stabilizes the needle.
- D. Flush with normal saline and recount the drop rate.
Correct answer: B
Rationale: In this scenario, the appropriate next step for the healthcare provider is to check for kinks in the tubing and raise the IV pole. These issues can commonly cause a slowed IV rate. Applying a warm compress (Choice A) may not address the underlying problem of kinked tubing or incorrect IV pole height. Adjusting the tape that stabilizes the needle (Choice C) is important for securement but is not the priority in this situation. Flushing with normal saline and recounting the drop rate (Choice D) should only be done after ruling out mechanical issues like kinks in the tubing.
3. What is the most important action for the nurse to take when caring for a client with a spinal cord injury experiencing autonomic dysreflexia?
- A. Elevate the head of the bed to 45 degrees.
- B. Monitor the client's respiratory rate.
- C. Administer an antihypertensive medication.
- D. Assess the client's blood glucose level.
Correct answer: A
Rationale: In a client with autonomic dysreflexia, the most critical action is to elevate the head of the bed to 45 degrees (A). This positioning helps reduce blood pressure, which is essential in managing autonomic dysreflexia. Monitoring the client's respiratory rate (B) is important for overall assessment but not the priority in this situation. Administering an antihypertensive medication (C) without addressing the positioning issue first can lead to further complications. Assessing the client's blood glucose level (D) is not directly related to autonomic dysreflexia and is not the initial priority in this scenario.
4. The healthcare provider is aware that malnutrition is a common problem among clients served by a community health clinic for the homeless. Which laboratory value is the most reliable indicator of chronic protein malnutrition?
- A. Low serum albumin level
- B. Low serum transferrin level
- C. High hemoglobin level
- D. High cholesterol level
Correct answer: A
Rationale: A low serum albumin level is the most reliable indicator of chronic protein malnutrition. Serum albumin levels reflect long-term protein status, and a significantly lowered level usually indicates ongoing protein deficiency. Other laboratory values, such as serum transferrin, hemoglobin, or cholesterol levels, may be affected by various factors and conditions, but serum albumin is a more specific marker for chronic protein malnutrition.
5. The healthcare provider is providing wound care to a client with a stage 3 pressure ulcer that has a large amount of eschar. The wound care prescription states 'clean the wound and then apply collagenase.' Collagenase is a debriding agent. The prescription does not specify a cleaning method. Which technique should the healthcare provider use to cleanse the pressure ulcer?
- A. Lightly coat the wound with povidone-iodine solution
- B. Irrigate the wound with sterile normal saline
- C. Flush the wound with sterile hydrogen peroxide
- D. Remove the eschar with a wet-to-dry dressing
Correct answer: B
Rationale: The correct technique to cleanse a wound when the prescription does not specify a cleaning method is to irrigate the wound with sterile normal saline. Sterile normal saline is the preferred solution for wound cleaning as it is gentle and does not damage healthy tissues. It helps in removing debris and maintaining a moist environment conducive to healing. Povidone-iodine solution and hydrogen peroxide can be harsh on tissues and delay wound healing. Removing eschar with a wet-to-dry dressing is a mechanical debridement method and should not be done without proper assessment and healthcare provider's order.
