A nurse is assisting with the preparation of a client who is scheduled for a paracentesis. In which of the following positions should the nurse place the client during the procedure?

Choice A reason: Filling the pad with sterile water is not necessary, as tap water can be used for an aquathermia pad without increasing the risk of infection or contamination.

Choice B reason: Using safety pins to secure the pad in place is not appropriate, as they can puncture or damage the pad and cause leakage or electric shock.

Choice C reason: Applying the pad for 45 min at a time is not recommended, as it can cause skin burns or tissue damage due to prolonged exposure to heat. The nurse should apply the pad for no more than 20 min at a time and check the skin frequently for signs of redness or blistering.

Choice D reason: Covering the pad prior to use is an important action, as it can prevent direct contact between the pad and the skin and reduce the risk of burns or irritation. The nurse should use a towel or a cloth to cover the pad before applying it to the affected area.

Choice A reason: Withholding the medication if the systolic blood pressure is less than 90 mm Hg is an appropriate action, as propranolol is a beta-blocker that can lower blood pressure and cause hypotension, which can impair tissue perfusion and cause dizziness, fainting, or shock.

Choice B reason: Requesting a dosage increase if the apical heart rate is less than 60/min is an inappropriate action, as propranolol can slow down the heart rate and cause bradycardia, which can lead to fatigue, weakness, or cardiac arrest. The nurse should monitor the apical pulse before administering propranolol and withhold it if it is less than 60/min.

Choice C reason: Informing the client to expect increased hair growth is an incorrect statement, as propranolol does not cause hypertrichosis or excessive hair growth. However, another beta-blocker, minoxidil, can cause this side effect.

Choice D reason: Administering the medication with an antacid is not an appropriate action, as antacids can interfere with the absorption of propranolol and reduce its effectiveness. The nurse should administer propranolol on an empty stomach or with food that does not contain antacids.
