ATI Comprehensive Predictor 2023 Exit Exam B Questions
Extract:
Question 1 of 5
A nurse is caring for a client who has a new prescription for sumatriptan for migraines. Which of the following instructions should the nurse include?
Correct Answer: A
Rationale: Taking sumatriptan at the onset of migraine symptoms is critical, as it is most effective when used early to abort the migraine by constricting cranial blood vessels and blocking pain pathways.
Choice B is incorrect because sumatriptan can be taken with or without food; food does not significantly affect its absorption.
Choice C is incorrect because drowsiness is not a common side effect; sumatriptan may cause dizziness or tingling, but alertness is usually unaffected.
Choice D is incorrect because sumatriptan is used for acute migraine treatment, not daily for prevention, which requires other medications like propranolol.
Question 2 of 5
A nurse is caring for a client who is experiencing alcohol withdrawal. Which of the following medications should the nurse anticipate administering?
Correct Answer: C
Rationale: Lorazepam, a benzodiazepine, is commonly administered during alcohol withdrawal to manage symptoms like tremors, seizures, and agitation by calming the central nervous system.
Choice A is incorrect because naltrexone is used for maintenance therapy to reduce alcohol cravings, not for acute withdrawal.
Choice B is incorrect because disulfiram is used to deter alcohol consumption, not to treat withdrawal symptoms.
Choice D is incorrect because acamprosate is used to maintain abstinence in alcohol use disorder, not for managing acute withdrawal.
Question 3 of 5
A nurse is caring for an infant who has coarctation of the aorta. Which of the following should the nurse identify as an expected finding?
Correct Answer: C
Rationale:
Choice A is not a typical sign of coarctation of the aorta. Nosebleeds can be caused by many factors, such as dry air, allergies, trauma, or bleeding disorders.
Choice B is also not a common finding in coarctation of the aorta. In fact, patients with this condition may have high blood pressure in the upper extremities due to the increased resistance of the narrowed aorta. This is because coarctation of the aorta is a congenital condition where the aorta is narrow, usually in the area where the ductus arteriosus inserts. This causes a decrease in blood flow to the lower body, resulting in weak or absent pulses in the femoral arteries.
Question 4 of 5
A nurse is reinforcing teaching with a client who has a new prescription for warfarin. Which of the following instructions should the nurse include?
Correct Answer: B
Rationale: Reporting unusual bleeding is critical with warfarin due to bleeding risk. Green leafy vegetables affect efficacy, antacids are unrelated, and weight gain is not expected.
Question 5 of 5
A nurse is assessing a client who has a spinal cord injury at the C5 level. Which of the following findings should the nurse expect?
Correct Answer: D
Rationale: A spinal cord injury at the C5 level typically preserves the function of the diaphragm (innervated by C3-C5) and shoulder muscles (deltoid and rotator cuff, innervated by C5), allowing the client to shrug shoulders.
Choice A is incorrect because a C5 injury affects the lower extremities, causing paraplegia or quadriplegia, depending on the extent.
Choice B is incorrect because, while respiratory function is partially preserved (diaphragm intact), the client may still have impaired accessory muscle function, leading to reduced respiratory capacity.
Choice C is incorrect because sensation loss typically occurs below the level of injury (below C5), not necessarily below the clavicles, and may vary in completeness.
