A nurse is preparing a client who is scheduled for an echocardiogram the following day. Which of the following instructions should the nurse include about the test?

It requires lying quietly on one side."

It might cause slight discomfort in the chest area."

"It is best to have no food or beverages the day of the test."

"It takes about 5 or 10 minutes."

Answer and Explanation

The Correct Answer is A

A. "It requires lying quietly on one side": This is the correct answer. During an echocardiogram, the client is typically asked to lie on their left side to obtain clear images of the heart. The test is non-invasive and involves using ultrasound waves to create images of the heart's structures.

B. "It might cause slight discomfort in the chest area": Echocardiograms are generally painless and do not cause discomfort. They are a non-invasive imaging technique that uses sound waves.

C. "It is best to have no food or beverages the day of the test": While the client may be instructed to avoid eating or drinking shortly before the test, this statement is too restrictive. The specific fasting instructions will be provided by the healthcare provider or facility.

D. "It takes about 5 or 10 minutes": The duration of an echocardiogram can vary, but it typically takes longer than 5 or 10 minutes. The test duration depends on various factors, including the complexity of the study and the information needed.

Correct Answer is ["A","B","C","E","F"]

Explanation

A. Disorientation:

This may indicate a neurological or cognitive issue and requires further assessment.

B. Barrel-shaped chest:

This is a characteristic finding in COPD, but any change or worsening may need evaluation.

C. Yellow sputum:

Yellow or greenish sputum may indicate an infection, and follow-up is needed.

D. Nebulizer use:

Nebulizer use is part of the prescribed treatment.

E. Ankle edema:

Edema can be a sign of heart failure or other cardiovascular issues and should be investigated.

F. SaO2 92%:

Oxygen saturation of 92% is below the normal range. It may indicate respiratory compromise and needs attention.

G. Clubbing of fingers:

While clubbing can be associated with chronic respiratory conditions, it is not an immediate concern.

H. Lives alone:

Living alone may impact the client's support system but does not require immediate medical attention.

A. Metabolic acidosis B. Metabolic alkalosis C. Respiratory acidosis D. Respiratory alkalosis

Correct Answer is C

Explanation

pH 7.22: Indicates acidosis (normal range: 7.35-7.45).

PaCO2 68 mm Hg: Elevated partial pressure of carbon dioxide, suggesting respiratory acidosis (normal range: 35-45 mm Hg).

Base excess -2: Indicates a mild metabolic acidosis.

PaO2 78 mm Hg: Within the normal range (80-100 mm Hg), indicating adequate oxygenation.

Saturation 80%: Below the normal range (95-100%), suggesting some degree of hypoxemia.

Bicarbonate 26 mEq/L: Elevated bicarbonate levels, suggesting metabolic compensation for the respiratory acidosis.

Therefore, the client is experiencing respiratory acidosis with partial metabolic compensation (mild metabolic acidosis).
