HESI CAT Exam 2024 Questions
Question 1 of 5
A 12-year-old client who had an appendectomy two days ago is receiving 0.9% normal saline at 50 ml/hour. The client's urine specific gravity is 1.035. What action should the nurse implement?
Correct Answer: A
Rationale: Encouraging fluids helps address dehydration and potentially high urine specific gravity, which is often related to inadequate fluid intake. In this scenario, the client may be at risk of dehydration due to the appendectomy and the high urine specific gravity. Encouraging popsicles and fluids of choice can help increase fluid intake and improve hydration status. The other options are not the priority at this time. Postural blood pressure measurements may be relevant for assessing fluid status but are not the immediate action needed. Obtaining a specimen for urinalysis and assessing bowel sounds are not the priority actions based on the client's condition.
Question 2 of 5
The healthcare provider changes a client's medication prescription from IV to PO administration and doubles the dose. The nurse notes in the drug guide that the prescribed medication, when given orally, has a high first-pass effect and reduces bioavailability. What action should the nurse implement?
Correct Answer: D
Rationale: The correct action for the nurse to implement is to consult with the pharmacist regarding the change in prescription. With the high first-pass effect of the medication when given orally, it reduces its bioavailability, meaning a dosage adjustment may be necessary to achieve the desired therapeutic effect. Continuing to administer the medication via the IV route (choice A) is not appropriate as the prescription has been changed to oral administration. Giving half the prescribed oral dose until consulting the provider (choice B) is not recommended without proper guidance, which should come from consulting with the pharmacist. Simply administering the medication orally as prescribed (choice C) without addressing the potential issue of reduced bioavailability may lead to suboptimal treatment outcomes.
Question 3 of 5
A client with chronic kidney disease has an arteriovenous (AV) fistula in the left forearm. Which observation by the nurse indicates that the fistula is patent?
Correct Answer: C
Rationale: Auscultation of a thrill on the left forearm is the correct observation indicating that the AV fistula is patent. A thrill is a palpable vibration or buzzing sensation felt over the fistula, indicating the presence of blood flow. Choices A, B, and D do not directly assess the patency of the fistula. Distended, tortuous veins in the left hand may indicate venous hypertension; a bounding radial pulse could suggest increased blood flow through an artery, but it does not confirm fistula patency; assessment of a bruit indicates turbulent blood flow, but it does not confirm patency.
Question 4 of 5
A client presents to the healthcare provider with fatigue, poor appetite, general malaise, and vague joint pain that improves mid-morning. The client has been using over-the-counter ibuprofen for several months. The healthcare provider makes an initial diagnosis of rheumatoid arthritis (RA). Which laboratory test should the nurse report to the healthcare provider?
Correct Answer: A
Rationale: The correct answer is A: Sedimentation rate. Sedimentation rate, Anti-CCP antibodies, and C-reactive protein are commonly used laboratory tests to indicate inflammation and help diagnose rheumatoid arthritis. An elevated sedimentation rate is a nonspecific indicator of inflammation in the body, which is often seen in RA. White blood cell count is not specific for RA and is not typically significant in the diagnosis. Anti-CCP antibodies are specific to RA and are useful in confirming the diagnosis. Activated Clotting Time is not relevant to the diagnosis of rheumatoid arthritis as it is not specific to this condition.
Question 5 of 5
After assessing an older adult with a suspected cerebrovascular accident (CVA), the nurse documents the client's right upper arm weakness and slurred speech. When the client complains of a severe headache and nausea, and the neurological assessment remains unchanged, which action should the nurse implement first?
Correct Answer: C
Rationale: In this scenario, the priority action for the nurse is to send the client for a computed tomography (CT) scan of the brain. A CT scan is crucial in assessing acute changes or bleeding that could influence treatment decisions in a suspected cerebrovascular accident (CVA). While addressing symptoms like headache and nausea is important, ruling out acute changes in the brain with a CT scan takes precedence in this situation. Collecting blood for coagulation times may be necessary but is not the initial priority. Obtaining a history of medication use, recent surgery, or injury is also important but not the first action to take when a CVA is suspected.
