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)
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 A
Explanation
A. Adventitious breath sounds:
Adventitious breath sounds refer to abnormal lung sounds heard upon auscultation of the chest. These sounds include crackles (rales), wheezes, rhonchi, and pleural friction rubs. In the context of fluid volume excess, particularly in the acute phase of a cerebrovascular accident (CVA) or stroke, adventitious breath sounds such as crackles are indicative of pulmonary edema. Pulmonary edema occurs when there is an excessive accumulation of fluid in the lungs, impairing gas exchange and leading to symptoms such as shortness of breath and respiratory distress.
B. Weak pulse:
A weak pulse may suggest poor perfusion or decreased cardiac output rather than fluid volume excess. While decreased cardiac output can be a consequence of heart failure, which may be associated with fluid volume excess, a weak pulse is not a direct indicator of fluid overload. In the acute phase of a CVA, a weak pulse may prompt further assessment for other cardiovascular complications or neurogenic shock.
C. Hypotension:
Hypotension, or low blood pressure, is not typically associated with fluid volume excess. Instead, hypotension may indicate hypovolemia, shock, or other underlying cardiovascular conditions. While hypotension can occur secondary to severe heart failure or fluid overload in some cases, it is not a direct indicator of fluid volume excess in the acute phase of a CVA.
D. Poor skin turgor:
Poor skin turgor is a clinical finding associated with dehydration rather than fluid volume excess. In dehydration, the skin loses its elasticity and becomes less resilient when pinched. In contrast, fluid volume excess is characterized by edema, which may manifest as pitting or non-pitting edema, rather than poor skin turgor. However, in fluid volume excess, the skin may appear stretched or taut due to the accumulation of fluid in the interstitial spaces.
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.
