A nurse is preparing a client to undergo a cardiac catheterization.
Which of the following tasks should the nurse perform prior to the procedure?

Choice A rationale:

Applying skin sealant on damp skin is not a correct technique when changing an ostomy appliance. Skin should be clean and thoroughly dry before applying any ostomy products. Moisture on the skin can interfere with the adhesion of the pouching system, leading to skin irritation and leakage.

Choice B rationale:

Removing the appliance before emptying the pouch is not the correct technique. Ostomy pouches are designed to be emptied without removing the entire appliance. Removing the pouch unnecessarily can cause discomfort to the client and may damage the surrounding skin. Regular emptying of the pouch while leaving the appliance in place is the appropriate practice.

Choice C rationale:

Ensuring that the skin is slightly damp for better adhesion of the pouch is not accurate. Ostomy pouches adhere best to clean, dry skin. Moisture on the skin can compromise the adhesive seal and lead to skin irritation. Therefore, the skin should be thoroughly dried before applying the ostomy pouching system.

Choice D rationale:

Tracing the size of the stoma onto the skin barrier is the correct technique when changing an ostomy appliance. The opening of the skin barrier (wafer) should match the size and shape of the stoma to ensure a proper fit. Tracing the stoma's size onto the barrier helps in cutting the opening to the appropriate size, preventing leakage and ensuring a secure fit around the stoma.

The correct answer is choice a. Maternal hypoglycemia.

Choice A rationale:

Maternal hypoglycemia can lead to decreased glucose availability for the fetus, which can result in fetal bradycardia due to reduced energy supply.

Choice B rationale:

Fetal anemia typically causes fetal tachycardia rather than bradycardia, as the fetus compensates for the lack of oxygen-carrying capacity by increasing the heart rate.

Choice C rationale:

Chorioamnionitis, an infection of the fetal membranes, usually causes fetal tachycardia due to the inflammatory response and fever.

Choice D rationale:

Maternal fever is more likely to cause fetal tachycardia rather than bradycardia, as the increased maternal temperature can lead to an increased fetal heart rate.
