HESI RN CAT Exam Quizlet

HESI RN

1. The nurse observes a client in a wheelchair with a vest restraint in place. What nursing intervention is most important for the nurse to implement?

A. Assess the need for continued restraint
B. Check the client for urinary incontinence
C. Determine skin integrity under the vest
D. Perform range-of-motion exercises on extremities

Correct answer: A

Rationale: The correct answer is to assess the need for continued restraint. This is the most important nursing intervention as it ensures the client's safety and autonomy. Checking for urinary incontinence (Choice B) may be important but is not the priority in this situation. Determining skin integrity under the vest (Choice C) is essential but not as crucial as assessing the need for continued restraint. Performing range-of-motion exercises (Choice D) is important for client mobility but not the priority when a restraint is in place.

2. A client who is bleeding after a vaginal delivery receives a prescription for methylergonovine (Methergine) 0.4 mg IM every 2 hours, not to exceed 5 doses. The medication is available in ampules containing 0.2 mg/ml. What is the maximum dosage in mg that the nurse should administer to this client?

A. Encourage oral fluids as tolerated
B. Decrease oral intake to 200 ml
C. Allow the client to have exactly 400 ml oral intake
D. Limit oral intake to 900 to 1,000 ml

Correct answer: D

Rationale: The maximum dosage the nurse should administer is 2 mg. This is calculated based on the prescription of 0.4 mg IM every 2 hours, not to exceed 5 doses. Since the medication is available in ampules containing 0.2 mg/ml, the nurse should administer 2 ml (0.2 mg/ml x 10 ml) for each dose, not exceeding 5 doses. Therefore, the nurse should limit the client's oral intake to 900 to 1,000 ml, to avoid exceeding the maximum dosage of 2 mg.

3. The nurse is assessing a client who has a new cast on the left arm. Which finding should the nurse report to the healthcare provider immediately?

A. Client reports itching under the cast
B. Client reports pain at the cast site
C. Client reports swelling of the fingers
D. Client reports warmth over the casted area

Correct answer: C

Rationale: Swelling of the fingers can indicate compromised circulation, which is a serious concern in a client with a new cast. It could suggest the development of compartment syndrome, a condition where increased pressure within the muscles can lead to impaired blood flow. This can result in tissue damage and should be addressed promptly. Itching under the cast, pain at the cast site, and warmth over the casted area are common findings after cast application and may not necessarily indicate an urgent issue requiring immediate reporting to the healthcare provider.

4. The nurse is assessing on the first postoperative day following thyroid surgery. Which laboratory value is most important for the nurse to monitor?

A. Calcium
B. Sodium
C. Chloride
D. Potassium

Correct answer: A

Rationale: Corrected Rationale: Monitoring calcium levels is crucial post-thyroid surgery to detect hypocalcemia, a common complication due to injury or removal of the parathyroid glands. Monitoring sodium, chloride, or potassium levels is not as vital in the immediate post-thyroid surgery period.

5. The healthcare provider prescribes amoxicillin (Amoxil) 1.5 grams PO daily, in equally divided doses to be administered every 8 hours. The medication is available in a bottle labeled Amoxicillin (Amoxil) suspension 200 mg/5 ml. How many ml should the nurse administer every 8 hours?

A. 10 ml
B. 12.5 ml
C. 15 ml
D. 17.5 ml

Correct answer: B

Rationale: To calculate the correct dosage, first, determine the total daily dose: 1.5 grams = 1500 mg. Since the medication is 200 mg/5 ml, for 1500 mg, the nurse needs to administer 1500/200 = 7.5 times the 5 ml dose. Therefore, 7.5 x 5 ml = 37.5 ml total daily dose. To administer this every 8 hours, divide 37.5 ml by 3 (8 hours intervals in a day) to get 12.5 ml to be administered every 8 hours. Choice A, C, and D are incorrect as they do not reflect the correct calculation of the dose based on the prescription and the available concentration.
