HESI CAT Exam 2022 Questions
Question 1 of 5
A new mother asks the nurse if the newborn infant has an infection because the healthcare provider prescribed a blood test called the TORCH screen test. Which response should the nurse offer to the mother's inquiry?
Correct Answer: D
Rationale: The TORCH screen test is used to detect infections that can affect the newborn by showing if there was exposure to these infections. Choice A is incorrect because the TORCH screen test is not specifically for identifying the etiology of neuro-sensory birth defects. Choice B is incorrect because the test does not determine the risk for inherited anomalies. Choice C is incorrect because the test is not used to identify the correct antibiotic for an infection, but rather to detect infections that may have affected the newborn.
Question 2 of 5
A premature infant weighing 1,200 grams at birth receives a prescription for beractant (Survanta) 120 mg endotracheal now and q6 hr for 24 hr. The recommended dose for beractant is 100 mg/kg birth weight per dose. Single-use vials of Survanta are labeled 100 mg/4 ml. What action should the nurse take?
Correct Answer: A
Rationale: The correct answer is to give 4.8 ml q6 hr. To calculate the dose, you divide the prescribed dose of 120 mg by the concentration of Survanta, which is 100 mg per 4 ml. This results in 4.8 ml per dose, as 120 mg · 100 mg/4 ml = 4.8 ml. Option B suggesting to notify the healthcare provider that the dose is too high is incorrect because the calculated dose of 4.8 ml is based on the recommended dose of 100 mg/kg birth weight. Option C suggesting to notify the healthcare provider that the dose is too low is incorrect as the calculated dose is based on the correct dosage calculation. Option D suggesting to give 1.2 ml q6 hr is incorrect because it doesn't align with the correct calculation.
Question 3 of 5
When designing a program to provide primary preventative health care to a community-based healthcare system, which service should the nurse consider for inclusion in the program? Select all that apply.
Correct Answer: A
Rationale: The correct answer is A: Breast screening for older women. In the context of primary preventative health care, breast screening for older women is crucial for early detection of breast cancer. Choice B, rehabilitation services for stroke victims, focuses on rehabilitative care rather than primary preventative care. Choice C, blood pressure assessments, is important for monitoring health status but not exclusive to primary prevention. Choice D, antepartum nutritional counseling, is more related to prenatal care than primary preventative health care. Therefore, choices B, C, and D do not directly align with the primary preventative health care objective of the grant.
Question 4 of 5
The nurse is caring for a comatose client. Which assessment finding provides the greatest indication that the client has an open airway?
Correct Answer: C
Rationale: The correct answer is C: "Bilateral breath sounds can be auscultated." This finding indicates that air is moving adequately in and out of both lungs, confirming an open airway. Options A, B, and D are incorrect. Asymmetrical chest expansion may indicate lung or chest wall abnormalities, percussion revealing dullness over the lung area may suggest consolidation or fluid, and turning the client q2h is a position change intervention to prevent complications, not a direct assessment of airway patency.
Question 5 of 5
The nurse should explain to a client with lung cancer that pleurodesis is performed to achieve which expected outcome?
Correct Answer: C
Rationale: The correct answer is C. Pleurodesis is a procedure used to prevent the re-accumulation of pleural effusion by creating adhesion between the pleurae. This helps prevent the formation of effusion fluid. Choices A, B, and D are incorrect because pleurodesis is not performed to debulk tumors, relieve empyema after pneumonectomy, or remove fluid from the intrapleural space. Understanding the purpose of pleurodesis is essential in providing accurate patient education and care.
