A nurse is caring for a client in the emergency department who has a preliminary diagnosis of a transient ischemic attack (TIA). Which of the following diagnostic testing should the nurse anticipate the provider to prescribe?

Computerized tomography angiography (CTA)

Complete blood count (CBC)

Prothrombin time (PT)

Transesophageal echocardiogram (TEE)

Answer and Explanation

The Correct Answer is A

A.Computerized tomography angiography (CTA)

This is a likely diagnostic test that the provider may prescribe. CTA uses computed tomography (CT) imaging to visualize the blood vessels in the brain and neck. It can help identify areas of stenosis, occlusion, or other abnormalities in the blood vessels that may contribute to the TIA symptoms.

B. Complete blood count (CBC)

A complete blood count (CBC) is a routine laboratory test that assesses various components of blood, such as red blood cells, white blood cells, and platelets. While it may not be specific to diagnosing a transient ischemic attack (TIA), it can help evaluate for underlying conditions such as anemia or thrombocytosis that could contribute to TIA symptoms or increase the risk of stroke.

C. Prothrombin time (PT)

Prothrombin time (PT) is a laboratory test that evaluates the clotting ability of blood and is typically used to monitor anticoagulant therapy. While abnormal coagulation parameters may be associated with certain conditions that predispose to TIA (such as atrial fibrillation), PT alone is not a specific diagnostic test for TIA.

D. Transesophageal echocardiogram (TEE)

This is another possible diagnostic test that the provider may prescribe. TEE is a specialized echocardiogram that provides detailed images of the heart structures by inserting an ultrasound probe

Correct Answer is B

Explanation

A. Excessive salivation:

Excessive salivation is not a common adverse effect of benztropine. Instead, anticholinergic medications like benztropine often cause dry mouth, which is more common than excessive salivation.

B. Difficulty voiding:

Difficulty voiding, or urinary retention, is a potential adverse effect of anticholinergic medications like benztropine. Anticholinergic drugs can cause relaxation of the detrusor muscle in the bladder, leading to urinary retention. Therefore, the nurse should instruct the client to report any difficulty or inability to urinate.

C. Diarrhea:

Diarrhea is not a common adverse effect of benztropine. Instead, anticholinergic medications like benztropine typically cause constipation due to their antimuscarinic effects on the gastrointestinal tract.

D. Slow pulse:

Slow pulse, or bradycardia, is not a common adverse effect of benztropine. Instead, anticholinergic medications like benztropine may cause tachycardia (increased heart rate) due to their effects on the autonomic nervous system.

Correct Answer is ["10"]

Explanation

To calculate the dose of valproic acid oral solution, the nurse should use the following formula:

Dose (mL) = Ordered dose (mg) / Concentration (mg/mL) x Volume (mL)

Plugging in the values from the question, we get:

Dose (mL) = 500 mg / (250 mg / 5 mL) x 5 mL

Simplifying, we get:

Dose (mL) = 500 mg / 50 mg x 5 mL

Dose (mL) = 10 mL

Therefore, the nurse should administer 10 of valproic acid oral solution to the patient.
