A nurse is assisting with the plan of care for a client who has a spinal cord injury and spasm-induced incontinence. Which of the following medications should the nurse anticipate a prescription for?

Choice A Reason:

Prothrombin time (PT) is a laboratory test that measures the time it takes for blood to clot is incorrect. While PT may be part of a comprehensive evaluation in some cases, it is not typically the initial diagnostic test performed for a TIA. A TIA is caused by a temporary disruption of blood flow to the brain, often due to an embolus or transient blockage in a cerebral artery, rather than a primary disorder of blood clotting.

Choice B Reason:

Complete blood count (CBC) is incorrect. A complete blood count (CBC) is a common laboratory test that evaluates the cellular components of the blood, including red blood cells, white blood cells, and platelets. While CBC can provide valuable information about hematological conditions such as anemia or thrombocytosis, it is not specific to diagnosing the cause of a TIA. TIA is primarily a vascular event related to transient ischemia in the brain rather than a disorder of blood cell counts.

Choice C Reason:

Computerized tomography angiography (CTA) is appropriate. CTA is a non-invasive imaging test that combines computed tomography (CT) scanning with contrast dye to visualize blood vessels throughout the body, including those in the brain. CTA can help identify any blockages, narrowing, or abnormalities in the blood vessels supplying the brain, which may be contributing to the TIA. It provides detailed images of the blood vessels' structure and can help guide further management and treatment decisions.

Choice D Reason:

Transesophageal echocardiogram (TEE) is inappropriate. Transesophageal echocardiogram (TEE) is an imaging test that provides detailed images of the heart and major blood vessels using sound waves. While TEE may be indicated in some cases of TIA to evaluate for potential cardiac sources of emboli (blood clots), such as atrial fibrillation or cardiac valve abnormalities, it is not typically the first-line diagnostic test performed in the emergency department setting for evaluating a TIA. Initial imaging studies such as CTA or magnetic resonance imaging (MRI) of the brain are usually prioritized to assess for acute changes in cerebral blood flow and potential causes of the TIA.

Choice A Reason:

Depression is incorrect. While depression can contribute to headaches in some individuals, it is more commonly associated with migraine headaches rather than tension-type headaches or cluster headaches. People with depression may experience changes in neurotransmitter levels and alterations in pain perception, which can exacerbate migraines. However, tension-type headaches and cluster headaches are generally less strongly associated with depression as a precipitating factor compared to migraines.

Choice B Reason:

Smoking is incorrect. Smoking can be a trigger for headaches in some individuals, particularly migraines, due to the vasoconstrictive effects of nicotine and other compounds in tobacco smoke. However, smoking is not universally recognized as a common precipitating factor for tension-type headaches or cluster headaches. While individuals with cluster headaches may have higher rates of smoking compared to the general population, it is not a factor commonly shared with tension-type headaches.

Choice C Reason:

Poor posture is incorrect. Poor posture can contribute to muscle tension and cervical spine strain, which may trigger tension-type headaches. However, poor posture is not typically considered a precipitating factor specific to cluster headaches. While tension-type headaches may be exacerbated by poor posture, cluster headaches are characterized by severe, unilateral pain typically centered around the eye or temple, with associated autonomic symptoms such as tearing, nasal congestion, or ptosis.

Choice D Reason:

Stress is correct. Stress is a well-established precipitating factor for both tension-type headaches and cluster headaches. Stress can lead to muscle tension and contraction, which are common triggers for tension-type headaches. Additionally, stress can also contribute to the onset or worsening of cluster headaches, although the exact mechanisms underlying this association are not fully understood. Therefore, stress is a common precipitating factor for both tension-type headaches and cluster headaches.
