The nurse is preparing to assist the burn surgeon in performing an escharotomy for a patient who has full-thickness circumferential burns that resulted in compartment syndrome. The nurse understands that the expected outcome of this procedure is to:

Choice A reason: The recovery position is not typically recommended for patients with acute pulmonary edema as it does not facilitate optimal breathing.

Choice B reason: The prone position is not generally recommended for acute pulmonary edema as it may not aid in improving oxygenation or breathing.

Choice C reason: The sitting up position, especially at an angle of 45 degrees or greater, is recommended for patients with acute pulmonary edema as it helps to facilitate breathing and decrease venous return to the heart.

Choice D reason: The Trendelenburg position is not recommended for acute pulmonary edema as it can increase the pressure in the chest and worsen breathing difficulties.

Choice A reason: Taking several deep breaths is not specifically related to the preparation for a renal system physical assessment. Deep breaths are more commonly associated with lung examination or to help the patient relax.

Choice B reason: Drinking several glasses of water before a renal assessment could potentially fill the bladder, which might interfere with palpation of the kidneys and make it uncomfortable for the patient.

Choice C reason: Emptying the bladder is the correct action before a renal system physical assessment. It allows for better palpation of the kidneys and other structures without the discomfort of a full bladder. It also prevents the possibility of the patient urinating involuntarily during the examination due to a full bladder.

Choice D reason: Providing a urine sample might be part of the overall renal assessment, but it is not necessary to do so immediately before the physical examination of the renal system. The sample can be collected at any time before or after the physical examination.
