A client with a complex cardiac history is scheduled for transesophageal echocardiography. Which of the following statements, if made by the nurse, is inappropriate?

“The test will provide a detailed profile of the heart’s electrical activity.”

“I will need to start an IV in your arm before the test.”

“Your throat may be a little sore after the exam.”

“You will need to refrain from eating and drinking 6-8 hours before this test.”

Answer and Explanation

The Correct Answer is A

A. "The test will provide a detailed profile of the heart’s electrical activity."

This statement is inappropriate because transesophageal echocardiography (TEE) primarily provides detailed images of the heart's structure, such as the valves and chambers, rather than focusing on the heart's electrical activity. The assessment of electrical activity is typically associated with electrocardiography (ECG or EKG) rather than echocardiography.

B. "I will need to start an IV in your arm before the test."

This statement is appropriate. It is common for medical procedures, including TEE, to require an intravenous (IV) line for administration of medications or fluids during or after the procedure.

C. "Your throat may be a little sore after the exam."

This statement is appropriate. TEE involves inserting a probe through the esophagus, and it is common for patients to experience a sore throat afterward due to the presence of the probe.

D. "You will need to refrain from eating and drinking 6-8 hours before this test."

This statement is appropriate. It is standard practice to ask patients to fast for a specific period before TEE to minimize the risk of complications, such as aspiration, during the procedure.

Correct Answer is D

Explanation

A. Coronary artery disease (CAD):

Coronary artery disease primarily affects the blood vessels supplying the heart muscle. Symptoms often include chest pain (angina) rather than pain in the lower extremities. The symptoms described in the scenario are not characteristic of CAD.

B. Arterial embolus:

An arterial embolus is a blood clot or debris that travels through the bloodstream and can block an artery. While it can cause decreased blood flow and pain, the presentation in the lower left leg and foot with relief of pain at rest is more suggestive of peripheral arterial disease (PAD) or intermittent claudication rather than an acute arterial embolus.

C. Raynaud disease:

Raynaud's disease is characterized by episodes of reduced blood flow to the extremities, usually triggered by cold or stress. It typically involves color changes (white, blue, red) in the fingers or toes. The symptoms described, including pain in the lower leg and foot during walking, are not typical of Raynaud's disease.

D. Intermittent claudication:

Intermittent claudication is a symptom associated with peripheral arterial disease (PAD). It involves pain or cramping in the legs during physical activity, such as walking, due to reduced blood flow to the muscles. Rest typically relieves the pain. The observation of a hairless leg and slight edema suggests potential vascular compromise in the lower extremity, supporting the diagnosis of intermittent claudication.

Correct Answer is ["125"]

Explanation

To calculate the amount of mL that the client should receive, we need to use the formula:

mL = (g * 5 mL) / mg

where g is the ordered dose of the medication, mg is the concentration of the medication, and mL is the volume of the solution.

Plugging in the given values, we get:

mL = (4 g * 5 mL) / 160 mg

Simplifying, we get:

mL = 0.125 g/mL

Multiplying by 1000 to convert grams to milligrams, we get:

mL = 125 mg/mL

Therefore, the client should receive 125 mL of the solution.
