HESI CAT Exam 2024 Questions
Question 1 of 5
When attempting to establish risk reduction strategies in a community, the nurse notes that regional studies indicate a high number of persons with growth stunting and irreversible mental deficiencies caused by hypothyroidism (cretinism). The nurse should seek funding to implement which screening measure?
Correct Answer: B
Rationale: Screening T4 levels in newborns is crucial as it helps in the early detection of hypothyroidism, which can prevent conditions like cretinism. Checking T3 levels in school-aged children (Choice A) is not the most appropriate measure for early detection of hypothyroidism in newborns. Monitoring TSH levels in women over 45 (Choice C) is not directly related to detecting hypothyroidism in newborns. Additionally, monitoring iodine levels in all persons over 60 (Choice D) is not specifically aimed at early detection of hypothyroidism in newborns, which is crucial to prevent cretinism.
Question 2 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 3 of 5
A young adult client was admitted 36 hours ago for a head injury that occurred as a result of a motorcycle accident. In the last 4 hours, the client's urine output has increased to over 200 ml/hour. Before reporting the finding to the healthcare provider, which intervention should the nurse implement?
Correct Answer: C
Rationale: The correct answer is to evaluate the urine osmolality and serum osmolality values. The increased urine output following a head injury could indicate diabetes insipidus, a condition characterized by excessive urination and extreme thirst. Evaluating osmolality is crucial for diagnosing diabetes insipidus. Choice A is incorrect because obtaining capillary blood samples for glucose every 2 hours is not the priority in this situation. Choice B is irrelevant to the client's current symptom of increased urine output. Choice D is also not the most appropriate intervention as the focus should be on assessing for a potential endocrine issue related to the increased urine output.
Question 4 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 5 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.
