HESI RN CAT Exit Exam Questions
Question 1 of 5
The nurse is administering total parenteral nutrition (TPN) via a central line at 75 ml/hour to a client who had a bowel resection 4 days ago. Which laboratory finding requires the most immediate intervention by the nurse?
Correct Answer: D
Rationale: The correct answer is D: Serum calcium of 7.8 mg/dL. This finding indicates hypocalcemia, which can lead to life-threatening cardiac arrhythmias. Low calcium levels can be caused by TPN administration or poor calcium absorption following bowel resection. Immediate intervention may include administering IV calcium gluconate. A: Blood glucose of 140 mg/dL is within the normal range and not an immediate concern. B: White blood cell count of 8000/mm³ is within the normal range and does not require immediate intervention. C: Serum potassium of 3.8 mEq/L is within the normal range and does not pose an immediate threat.
Question 2 of 5
The nurse is planning care for a client who is receiving phenytoin (Dilantin) for seizure control. Which intervention is most important to include in this client's plan of care?
Correct Answer: C
Rationale: The correct answer is C. Implement seizure precautions. This is the most important intervention because phenytoin is an antiepileptic drug, and its purpose is to control seizures. Seizure precautions aim to prevent injury during a seizure, ensuring the client's safety. Monitoring serum calcium levels (A) is not directly related to phenytoin therapy. Obtaining a baseline electrocardiogram (B) is not a priority unless there are specific cardiac concerns. Encouraging a low-protein diet (D) is not necessary for phenytoin therapy.
Question 3 of 5
The nurse is planning discharge teaching for a client with chronic kidney disease. Which information is most important for the nurse to provide this client?
Correct Answer: C
Rationale: Rationale: Choice C is correct because sudden weight gain can indicate fluid retention, a common complication in chronic kidney disease. This can lead to serious issues like heart failure. Monitoring weight daily (A) is important, but specifically reporting significant gains promptly (C) is crucial. Limiting fluid intake (B) is important, but not the top priority. Increasing protein intake (D) may worsen kidney function, so it's not recommended.
Question 4 of 5
A client is taught how to collect a 24-hour urine specimen. Which statement indicates understanding of the procedure?
Correct Answer: D
Rationale: The correct answer is D because discarding the first morning specimen ensures accurate collection starts. Choice A is incorrect because refrigeration is unnecessary for a 24-hour urine collection. Choice B is incorrect as the first void should be included. Choice C is incorrect as there's no need to keep the urine on ice.
Question 5 of 5
A nurse is planning care for a client who is newly diagnosed with diabetes mellitus. Which instruction should the nurse include in this client¢â‚¬â„¢s teaching plan?
Correct Answer: C
Rationale: The correct answer is C: Rotate insulin injection sites. This instruction is crucial to prevent lipohypertrophy, which can lead to inconsistent insulin absorption. By rotating injection sites, the client ensures proper insulin absorption and prevents complications. Checking blood glucose levels once a week (B) is not frequent enough for proper diabetes management. Avoiding all forms of sugar (A) is an outdated approach, as moderation is key. Monitoring urine ketone levels (D) is not as reliable as blood ketone testing for assessing diabetic ketoacidosis risk.
