Fundamentals of Nursing HESI
1. A healthcare professional is instructing an AP about caring for a client who has a low platelet count. Which of the following instructions is the priority for measuring vital signs for this client?
- A. Avoid measuring the client’s temperature rectally.
- B. Count the client’s radial pulse for 30 seconds and multiply it by 2.
- C. Count the client’s respirations discreetly.
- D. Allow the client to rest for 5 minutes before measuring their BP.
Correct answer: A
Rationale: The correct answer is to avoid measuring the client’s temperature rectally. Rectal temperatures can cause bleeding in clients with low platelet counts. It is crucial to avoid invasive methods that could increase the risk of bleeding or discomfort. Choice B, counting the radial pulse, is not directly related to the risk of bleeding in a client with low platelet count. Choice C, counting respirations discreetly, is important for accuracy but is not the priority when considering the risk of bleeding. Choice D, letting the client rest before measuring blood pressure, is beneficial but is not the priority in preventing potential harm due to low platelet counts.
2. A client with a diagnosis of myocardial infarction (MI) is being treated. Which laboratory value would be most concerning?
- A. Troponin level of 0.5 ng/mL
- B. Creatine kinase-MB (CK-MB) of 5.0 ng/mL
- C. Serum potassium of 4.5 mEq/L
- D. Blood glucose of 180 mg/dL
Correct answer: A
Rationale: A troponin level of 0.5 ng/mL is elevated, indicating myocardial damage, making it the most concerning finding in a client with a myocardial infarction (MI). Troponin is a highly specific marker for cardiac muscle damage, and elevated levels suggest ongoing injury to the heart muscle. While Creatine kinase-MB (CK-MB) is also a cardiac enzyme, troponin is more specific and sensitive for myocardial damage. Serum potassium and blood glucose levels are important parameters to monitor in MI patients, but in this scenario, the elevated troponin level takes precedence as it directly reflects cardiac injury.
3. A nurse in a surgical suite notes documentation on a client's medical record stating that he has a latex allergy. In preparation for the client's procedure, which of the following precautions should the nurse take?
- A. Ensure sterilization of non-disposable items with ethylene oxide
- B. Wrap monitoring cords with stockinette and secure them with non-latex tape
- C. Cleanse latex ports on IV tubing with chlorhexidine before administering medication
- D. Wear hypoallergenic latex gloves that are powder-free
Correct answer: B
Rationale: In this scenario, the nurse should take precautions to prevent latex exposure to the client due to his latex allergy. Wrapping monitoring cords with stockinette and securing them with non-latex tape helps to minimize the risk of latex contact with the client. Choice A is incorrect as sterilizing non-disposable items with ethylene oxide does not specifically address the avoidance of latex exposure. Choice C involves using latex ports on IV tubing, which can pose a risk of allergic reaction in a client with a latex allergy. Choice D suggests wearing latex gloves, even if hypoallergenic, which can still trigger a reaction in individuals with latex allergy. Therefore, the best option is to choose non-latex materials like stockinette and non-latex tape to prevent direct contact with latex.
4. A healthcare professional is caring for a client with a chest tube. Which observation requires immediate intervention?
- A. Constant bubbling in the suction control chamber
- B. Intermittent bubbling in the water seal chamber
- C. Drainage of 50 ml per hour
- D. Crepitus around the insertion site
Correct answer: D
Rationale: Crepitus around the chest tube insertion site may indicate subcutaneous emphysema, a serious condition that requires immediate attention. It can be a sign of an air leak in the lung or surrounding tissues. Constant bubbling in the suction control chamber is expected in a functioning chest tube system as it indicates proper suction. Intermittent bubbling in the water seal chamber is also normal, showing that the system is functioning correctly, allowing air to escape but not re-enter. Drainage of 50 ml per hour is within the expected range for chest tube output and does not require immediate intervention unless there are other concerning signs such as rapid increase or a sudden change in color or consistency.
5. 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.
