A patient arrives in the emergency department exhibiting symptoms of a cerebrovascular accident (CVA). Which diagnostic evaluations would the nurse anticipate before treatment is initiated?
Prothrombin level
Brain CT or MRI
Chest x-ray
Lumbar puncture
The Correct Answer is B
Choice A rationale
While prothrombin level is an important test in evaluating blood clotting disorders, it is not typically used in the initial diagnostic evaluations for a cerebrovascular accident (CVA) or stroke.
Choice B rationale
Brain CT or MRI scans are commonly used in the initial diagnostic evaluations for a CVA. These imaging tests can show bleeding in the brain, an ischemic stroke, a tumor, or other conditions.
Choice C rationale
A chest x-ray is not typically used in the initial diagnostic evaluations for a CVA. It is more commonly used to diagnose conditions affecting the lungs and heart.
Choice D rationale
A lumbar puncture, or spinal tap, may be used in some cases to help diagnose a CVA, but it is not typically part of the initial diagnostic evaluations.

Correct Answer is A
Explanation
Choice A rationale
Triptans, a class of medications commonly used to treat migraines, can cause vasoconstriction, or narrowing of the blood vessels. This can be problematic for patients with angina, a condition characterized by reduced blood flow to the heart. Vasoconstriction could potentially exacerbate this condition, leading to an increased risk of a heart attack. Therefore, the use of triptans may be contraindicated in patients with angina.
Choice B rationale
While asthma is a serious condition that requires careful management, it is not typically considered a contraindication for the use of triptans. Triptans work primarily on the blood vessels in the brain and do not typically interact with the bronchial tubes affected by asthma.
Choice C rationale
Age alone is not typically a contraindication for the use of triptans. However, older adults may have a higher risk of certain health conditions, such as heart disease, which could make the use of triptans more risky. It’s important for healthcare providers to consider the overall health status of the patient, not just their age, when deciding whether to prescribe triptans.
Choice D rationale
While stress can certainly exacerbate migraines, it is not typically a contraindication for the use of triptans. Triptans are designed to relieve the pain and other symptoms of migraines, regardless of their cause. If a patient’s migraines are triggered by stress, it may be beneficial to explore stress management techniques in addition to medication.
Correct Answer is C
Explanation
Choice C rationale
When providing care for a comatose patient, a nurse should evaluate motor responses by observing the patient’s response to painful stimuli. This can be done by applying a painful stimulus, such as a trapezius pinch or nailbed pressure, and observing the patient’s motor response. Purposeful or semi-purposeful movements, such as localizing or withdrawing from pain, can provide valuable information about the patient’s level of consciousness and neurological function.
Choice A rationale
The Romberg test is used to evaluate balance and is not typically used to evaluate motor responses in a comatose patient.
Choice B rationale
Assessing the patient’s sensitivity to temperature and touch can provide information about sensory function, but it does not directly evaluate motor responses.
Choice D rationale
Observing the reaction of pupils to light can provide information about cranial nerve function, but it does not directly evaluate motor responses.
