Fundamentals of Nursing HESI
1. Heparin 20,000 units in 500 ml D5W at 50 ml/hour has been infusing for 5.5 hours. How much heparin has the client received?
- A. 11,000 units.
- B. 13,000 units.
- C. 15,000 units.
- D. 17,000 units.
Correct answer: A
Rationale: To calculate the total amount of heparin received, multiply the infusion rate (50 ml/hour) by the total infusion time (5.5 hours). This results in 275 ml of the solution infused. Since there are 20,000 units of heparin in 500 ml, there are 800 units per ml. Therefore, 275 ml contains 220,000 units. However, the heparin is diluted in 500 ml, so the client has received half of this amount, which is 110,000 units. Therefore, the correct answer is 11,000 units. Choices B, C, and D are incorrect as they do not reflect the correct calculation based on the provided information.
2. A healthcare provider is planning to initiate IV therapy for an older adult client who requires IV fluids. Which of the following actions should the healthcare provider take?
- A. Insert the IV catheter without using a tourniquet.
- B. Use the tourniquet minimally or not at all to avoid injury to fragile skin or veins.
- C. Insert the IV catheter at a 45-degree angle.
- D. Use a smaller gauge catheter to reduce vein trauma.
Correct answer: B
Rationale: When initiating IV therapy in older adults, it is essential to use the tourniquet minimally or not at all to prevent potential injury to fragile skin or veins. The use of a tourniquet can lead to increased venous pressure and potentially cause vein damage in older adult clients. Choice A is incorrect because inserting the IV catheter without a tourniquet can make locating veins more challenging. Choice C is incorrect as inserting the IV catheter at a 45-degree angle is not a recommended practice and can increase the risk of complications. Choice D is incorrect because using a smaller gauge catheter may not be appropriate for older adults who may require a larger gauge catheter for adequate fluid administration.
3. A healthcare provider is caring for several clients who are receiving oxygen therapy. Which client should the provider assess most frequently for manifestations of oxygen toxicity?
- A. 100% oxygen via partial rebreathing mask
- B. 2 liters per minute via nasal cannula
- C. 4 liters per minute via simple mask
- D. 6 liters per minute via face mask
Correct answer: A
Rationale: When a client is receiving 100% oxygen via a partial rebreathing mask, there is a higher risk for oxygen toxicity due to the higher concentration of oxygen delivered. This client should be assessed most frequently for manifestations of oxygen toxicity. Choices B, C, and D are less likely to result in oxygen toxicity compared to 100% oxygen delivery via a partial rebreathing mask.
4. The nurse is assessing body alignment for a patient who is immobilized. Which patient position will the nurse use?
- A. Supine position
- B. Lateral position
- C. Lateral position with positioning supports
- D. Supine position with no pillow under the patient's head
Correct answer: B
Rationale: When assessing body alignment for an immobilized patient, the nurse should use the lateral position. This position helps in assessing alignment and preventing complications such as pressure ulcers. The supine position (Choice A) may not provide an accurate assessment of body alignment in an immobilized patient. While a lateral position with positioning supports (Choice C) may be used for comfort, it is not specifically for assessing body alignment. Using the supine position without a pillow under the patient's head (Choice D) is not ideal for assessing body alignment in an immobilized patient as it may not accurately reflect the patient's overall alignment.
5. The nurse is providing education about the importance of proper foot care to a patient diagnosed with diabetes mellitus. Which primary goal is the nurse trying to achieve?
- A. Prevention of plantar warts
- B. Prevention of foot fungus
- C. Prevention of neuropathy
- D. Prevention of amputation
Correct answer: D
Rationale: The correct answer is D: Prevention of amputation. Patients with diabetes are at a higher risk of foot complications, such as ulcers, infections, and ultimately, amputations. Proper foot care education aims to prevent these serious complications. Choices A, B, and C are incorrect because while they are also important aspects of foot care, the primary goal in diabetes management is to prevent severe outcomes like amputation.
