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 C

Explanation

A. Semicomatose:

This term suggests a state between consciousness and coma. A patient who is semicomatose may exhibit some level of responsiveness but is typically unresponsive or only responds to intense stimuli.

B. Somnolent:

Somnolence refers to a state of drowsiness or sleepiness. A somnolent patient may appear sleepy, have difficulty staying awake, and may be slow to respond to stimuli. However, the withdrawal from painful stimuli described in the scenario suggests a higher level of responsiveness than what would typically be expected in a somnolent state.

C. Lethargic:

Lethargy describes a state of reduced alertness or responsiveness. A lethargic patient may appear drowsy, sluggish, and have diminished responses to stimuli. The description of the patient as stuporous (having a decreased level of consciousness) but still reacting by withdrawing from painful stimuli aligns with the characteristics of lethargy.

D. Comatose:

Coma refers to a state of profound unconsciousness where the patient is unresponsive to all stimuli, including painful stimuli. A comatose patient does not demonstrate any purposeful movement or response to stimuli. Since the patient in the scenario exhibits some response to painful stimuli by withdrawing, they do not meet the criteria for being comatose.

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.
