A nurse is collecting data about a client's cardiac functioning. The nurse auscultates an S3 sound. Which of the following causes should the nurse suspect?

Atrial gallop

Ventricular gallop

Closing of semilunar valves

Closing of the atrioventricular valves

Answer and Explanation

The Correct Answer is B

A. Atrial gallop: An atrial gallop is associated with the S4 heart sound, which occurs before the S1 sound due to the atrial contraction.

B. Ventricular gallop: An S3 heart sound is known as a ventricular gallop and is often a sign of heart failure or fluid overload. It occurs during early diastole when the ventricle fills rapidly.

C. Closing of semilunar valves: The closing of the semilunar valves (aortic and pulmonary) produces the S2 heart sound, not the S3 sound.

D. Closing of the atrioventricular valves: The closing of the atrioventricular valves (mitral and tricuspid) produces the S1 heart sound, not the S3 sound.

Correct Answer is C

Explanation

A. Check the client's blood pressure. While it is important to monitor vital signs after surgery, checking blood pressure is not the first action unless the client is showing signs of instability.

B. Check the client's IV catheter insertion site. Assessing the IV site is important for identifying complications such as infiltration or phlebitis, but this is not the priority.

C. Check the level of the client's pain. Pain assessment is the priority because unmanaged pain can affect recovery and indicate complications such as bleeding or infection. Managing pain is crucial in the postoperative period.

D. Check the client's bowel sounds. Assessing bowel sounds is important following abdominal surgery, but it is not the first priority compared to pain assessment.

A. To provide analgesia B. To prevent blood clotting C. To reduce inflammation D. To prevent fever

Correct Answer is B

Explanation

A. To provide analgesia: While aspirin can reduce pain, its primary use following a myocardial infarction is not for analgesia. Other medications are used for pain management in this scenario.

B. To prevent blood clotting: Aspirin is prescribed following a myocardial infarction to inhibit platelet aggregation and prevent blood clots, which can reduce the risk of future cardiac events. This is the correct rationale for aspirin use in coronary artery disease.

C. To reduce inflammation: Although aspirin has anti-inflammatory properties, the primary reason for prescribing it after a myocardial infarction is to prevent blood clots, not to reduce inflammation.

D. To prevent fever: Aspirin can reduce fever, but this is not the reason it is prescribed after a myocardial infarction.
