Which diagnostic test may be prescribed to evaluate for the presence of a pulmonary embolism?

Stress testing

D-Dimer

Electrocardiogram

Pulmonary function testing

Answer and Explanation

The Correct Answer is B

A. Stress testing evaluates cardiac function and ischemia but is not used to diagnose a pulmonary embolism (PE).
B. D-Dimer is correct. D-Dimer is a blood test that detects fibrin degradation products, which are elevated when a blood clot forms and breaks down, making it a useful screening test for pulmonary embolism. However, a positive D-Dimer is not diagnostic, and further imaging (e.g., CT pulmonary angiography) is required.
C. Electrocardiogram (ECG) may show changes (e.g., sinus tachycardia, right heart strain) but does not confirm PE.
D. Pulmonary function testing assesses lung diseases like COPD or asthma but is not used to diagnose PE.

Correct Answer is B

Explanation

A. Obtaining an ECG is important but not the first priority. The immediate goal is to reduce the heart's oxygen demand.
B. Having the client sit down immediately is correct. Stopping activity reduces cardiac workload and oxygen demand, preventing further ischemia or infarction.
C. Assessing vital signs is important but should be done after stopping activity. While vital signs provide critical information, immediate intervention is needed first.
D. Administering sublingual nitroglycerin is appropriate but should be done after ensuring the client is seated. This prevents hypotension and syncope from occurring while standing.

A. To increase caloric intake by snacking throughout the day B. To allow for more social interaction during meals C. To ensure all food groups are consumed daily D. To reduce the risk of dyspnea during meals

Correct Answer is D

Explanation

A. While increasing caloric intake is important, the primary reason for small, frequent meals is to prevent dyspnea.
B. Social interaction is beneficial, but it is not the main reason for recommending small, frequent meals.
C. Ensuring a balanced diet is important, but not the specific reason for this recommendation.
D. Eating large meals can cause abdominal distention and pressure on the diaphragm, leading to dyspnea. Small, frequent meals help prevent this.
