During defecation, the client experiences decreased cardiac output related to the Valsalva maneuver. After the Valsalva maneuver, the nurse assesses the client's vital signs and expects to observe which of the following?
A) An increase in the client's blood pressure
B) A decrease in the client's blood pressure
C) An increase in the client's respiratory rate
D) A decrease in the client's respiratory rate
Ans: A
When an individual bears down to defecate, the increased pressures in the abdominal and thoracic cavities result in a decreased blood flow and a temporary decrease in cardiac output. Once the bearing down ceases, the pressure is lessened, and a larger than normal amount of blood returns to the heart; this act elevates the client's blood pressure.
