HESI CAT Exam Quizlet

HESI LPN

1. A client receives a prescription for acetylcysteine (Mucomyst) 1.4 grams per nasogastric tube q4 hours. Acetylcysteine is available as a 10% solution (10 grams/100ml). How many ml of the 10% solution should the nurse administer per dose?

A. 7
B. 10
C. 14
D. 1.4 grams of acetylcysteine is equivalent to 14 ml of a 10% solution.

Correct answer: D

Rationale: To determine the amount of the 10% acetylcysteine solution to administer, convert the 1.4 grams to milligrams (1.4 grams = 1400 mg). Then, as the 10% solution contains 10 grams (10,000 mg) per 100 ml, it means there are 1000 mg of acetylcysteine in every 10 ml of the solution (10,000 mg / 100 ml = 100 mg/ml). Therefore, to administer 1400 mg (1.4 grams) of acetylcysteine, the nurse should give 14 ml of the 10% solution. Choices A, B, and C are incorrect as they do not accurately convert the amount of acetylcysteine to the corresponding volume of the 10% solution.

2. A client with a history of dementia has become increasingly confused at night and is picking at an abdominal surgical dressing and the tape securing the intravenous (IV) line. The abdominal dressing is no longer occlusive, and the IV insertion site is pink. What intervention should the nurse implement?

A. Replace the IV site with a smaller gauge.
B. Redress the abdominal incision.
C. Leave the lights on in the room at night.
D. Apply soft bilateral wrist restraints.

Correct answer: C

Rationale: The correct intervention for a client with dementia who is becoming increasingly confused at night and interfering with dressings and IV lines is to leave the lights on in the room at night. This intervention can help reduce confusion and disorientation. Choice A is incorrect because changing the IV site gauge is not the priority in this situation. Choice B is not necessary unless there are signs of infection or other complications at the abdominal incision site, which are not mentioned in the scenario. Choice D should be avoided as using restraints should be a last resort and is not indicated in this case.

3. A client taking clopidogrel reports the onset of diarrhea. Which nursing action should the nurse implement first?

A. Observe the appearance of the stool
B. Assess the client’s skin turgor
C. Review the client’s laboratory values
D. Auscultate the client’s bowel sounds

Correct answer: A

Rationale: Observing the stool’s appearance should be implemented first as it helps determine the nature and possible severity of the diarrhea, which is essential in managing the side effect. Assessing skin turgor (Choice B) is not the priority in this situation. Reviewing laboratory values (Choice C) can provide additional information but is not the initial step. Auscultating bowel sounds (Choice D) is not the priority when the client is experiencing diarrhea.

4. When conducting diet teaching for a client who is on a postoperative full liquid diet, which foods should the nurse encourage the client to eat?

A. Vanilla frozen yogurt
B. Vegetable juice
C. Clear beef broth
D. Canned fruit cocktail

Correct answer: A

Rationale: The correct answer should be provided as choice E: Vanilla frozen yogurt. For a postoperative full liquid diet, the nurse should encourage the client to eat foods that are fully liquid and easy to digest. Vanilla frozen yogurt is a suitable choice as it provides calories and nutrients while being in a liquid form. Creamy peanut butter, vegetable juice, and canned fruit cocktail are not appropriate for a full liquid diet as they are not fully liquid and may not be easy to digest. Creamy peanut butter is solid, vegetable juice is not fully liquid, and canned fruit cocktail contains solid pieces.

5. An older adult resident of a long-term care facility has a 5-year history of hypertension. The client has a headache and rates the pain 5 on a pain scale of 0 to 10. The client’s blood pressure is currently 142/89. Which interventions should the nurse implement? (Select all that apply)

A. Administer the scheduled daily dose of lisinopril.
B. Assess the client for postural hypotension.
C. Notify the healthcare provider immediately.
D. Provide a PRN dose of acetaminophen for the headache.

Correct answer: A

Rationale: In this scenario, the client's blood pressure of 142/89 is within an acceptable range for someone with a history of hypertension. The client's headache with a pain rating of 5 does not warrant an immediate notification to the healthcare provider. Administering the scheduled dose of lisinopril is appropriate to manage the client's hypertension. Assessing the client for postural hypotension is relevant due to the client's age and hypertension history. Providing a PRN dose of acetaminophen for the headache is not necessary at this point as the pain level is moderate and can be managed with other interventions.
