HESI Fundamentals Study Guide
1. A nurse is preparing to administer multiple medications to a client who has an enteral feeding tube. Which of the following actions should the nurse plan to take?
- A. Dissolve each medication in 5 mL of sterile water.
- B. Draw up each medication separately in the syringe.
- C. Push the syringe plunger gently if feeling resistance.
- D. Flush the tube with 15 mL of sterile water.
Correct answer: D
Rationale: The correct action the nurse should take when administering multiple medications to a client with an enteral feeding tube is to flush the tube with 15-30 mL of sterile water before and between medications, and 30-60 mL after the last medication. This helps prevent clogging and ensures each medication is delivered effectively. Choice A is incorrect as medications should not be dissolved in water for administration through an enteral feeding tube. Choice B is incorrect because each medication should be drawn up and administered separately to prevent any potential interactions. Choice C is incorrect as resistance while pushing the plunger may indicate a problem that needs to be addressed before continuing with the administration.
2. The patient is being taught about flossing and oral hygiene. What instruction will the nurse include in the teaching session?
- A. Using waxed floss helps prevent bleeding
- B. Flossing removes plaque and tartar from the teeth
- C. Flossing at least 3 times a day is beneficial
- D. Applying toothpaste before flossing is harmful
Correct answer: B
Rationale: The correct answer is B. Flossing is essential for removing plaque and tartar between teeth, contributing to better oral hygiene. Choice A is not entirely accurate as waxed floss may not solely prevent bleeding. Flossing three times a day, as mentioned in choice C, can be excessive and unnecessary, while choice D is incorrect as applying toothpaste before flossing is not harmful but might not provide additional benefits.
3. A nurse is caring for an older adult client who becomes agitated when the nurse requests the client’s dentures be removed prior to surgery. Which of the following responses should the nurse make?
- A. You seem worried. Are you concerned someone may see you without your teeth?
- B. Don't worry, it’s just for the surgery.
- C. You need to follow the instructions.
- D. The dentures need to be removed for a reason.
Correct answer: D
Rationale: The correct response is to provide a clear rationale for the request, as stated in option D. By explaining the purpose behind removing the dentures, the nurse helps the client understand the necessity, which can reduce agitation and promote cooperation. Option A demonstrates empathy by addressing the client's potential concern about being seen without dentures but lacks a direct explanation. Option B dismisses the client's feelings with a casual statement that may not address the underlying issue. Option C is authoritarian and lacks empathy, potentially escalating the client's agitation.
4. Which task can the RN delegate to an unlicensed assistive personnel (UAP)?
- A. Take a history on a newly admitted client
- B. Adjust the rate of a gastric tube feeding
- C. Check the blood pressure of a 2-hour postoperative client
- D. Check on a client receiving chemotherapy
Correct answer: C
Rationale: The correct answer is C. Checking the blood pressure of a 2-hour postoperative client is a task that can be safely delegated to an unlicensed assistive personnel (UAP) as it falls within their scope of practice. This task is routine and does not require specialized nursing knowledge or critical decision-making. Options A, B, and D involve tasks that require a higher level of training and critical thinking beyond the scope of a UAP. Taking a history, adjusting tube feeding rates, and monitoring a client receiving chemotherapy are responsibilities that should be performed by licensed healthcare providers who have the necessary skills and training.
5. 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.
