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 slowing of client's heart rate
a decrease in the client's blood pressure
an increase in the client's respiratory rate
a decrease in the client's respiratory rate
The Correct Answer is A
a) A slowing of the client's heart rate: The Valsalva maneuver (straining during defecation) can cause a transient increase in intra-abdominal pressure, which triggers vagal stimulation, leading to a slowing of the heart rate (bradycardia).
b) A decrease in the client's blood pressure: The Valsalva maneuver may initially cause an increase in blood pressure, followed by a drop after the maneuver is released. The immediate effect is a slowing of the heart rate, not a decrease in blood pressure.
c) An increase in the client's respiratory rate: The Valsalva maneuver typically causes a temporary decrease in respiratory rate due to the strain on the body.
d) A decrease in the client's respiratory rate: The Valsalva maneuver does not typically result in a significant decrease in respiratory rate. Instead, it is more likely to cause a brief alteration in heart rate and blood pressure.

Correct Answer is A
Explanation
a) Habitual laxative use is the most common cause of chronic constipation: Chronic laxative use can lead to dependency, where the bowel no longer functions normally without the stimulant. Over time, this can cause chronic constipation.
b) Chronic constipation is nothing to be concerned about: Chronic constipation can be a sign of an underlying issue, such as a bowel obstruction, and it should not be dismissed.
c) A laxative that works by a different method should be used: While there are different types of laxatives, simply switching methods without addressing the underlying cause of dependency may not be effective in resolving chronic constipation.
d) If laxatives are not effective, the client should begin to use enemas: Enemas may be an acute solution, but relying on them regularly can be harmful. The focus should be on addressing the underlying issue of laxative dependency.
