A nurse is providing skin care for a client who has urinary incontinence. Which of the following actions should the nurse take?

Choice A reason: This is not the correct answer because this statement by the client indicates that the client understands the dietary restrictions and guidelines that are necessary after bariatric surgery. A liquid/pureed diet and limited fluid intake are recommended to prevent complications such as nausea, vomiting, dehydration, and dumping syndrome.

Choice B reason: This is the correct answer because this statement by the client indicates that the client does not understand the importance of a thorough evaluation by the surgeon prior to the procedure. Bariatric surgery is a major surgery that involves significant risks and benefits, and requires careful consideration of the client's medical history, physical condition, psychological status, and readiness for lifestyle changes. The surgeon should assess the client's eligibility, suitability, and expectations for the surgery, and provide informed consent and education.

Choice C reason: This is not the correct answer because this statement by the client indicates that the client understands the basic principles and types of bariatric surgery. Bariatric surgery can be classified into restrictive, malabsorptive, or combined procedures, depending on how they affect the size of the stomach and the absorption of food. The most common types of bariatric surgery are gastric bypass, sleeve gastrectomy, and adjustable gastric banding.

Choice D reason: This is not the correct answer because this statement by the client indicates that the client understands the long-term implications and commitments of bariatric surgery. Bariatric surgery is not a quick fix or a magic solution for obesity, but rather a tool that helps the client achieve and maintain weight loss and improve health outcomes. The client should be aware that bariatric surgery requires lifelong changes in diet, exercise, medication, supplementation, and follow-up care.

Choice A reason: Hypernatremia is a condition of high sodium levels in the blood. It can cause symptoms such as thirst, dry mouth, confusion, agitation, and seizures. It is not likely to cause postural hypotension, which is a drop in blood pressure when changing positions.

Choice B reason: Hyponatremia is a condition of low sodium levels in the blood. It can cause symptoms such as headache, nausea, vomiting, muscle weakness, fatigue, and confusion. It can also cause postural hypotension, as sodium helps regulate fluid balance and blood pressure.

Choice C reason: Hyperkalemia is a condition of high potassium levels in the blood. It can cause symptoms such as muscle weakness, paralysis, irregular heartbeat, and cardiac arrest. It is not likely to cause postural hypotension, which is more related to fluid and sodium levels.

Choice D reason: Hypokalemia is a condition of low potassium levels in the blood. It can cause symptoms such as muscle cramps, weakness, fatigue, constipation, and arrhythmias. It is not likely to cause postural hypotension, which is more related to fluid and sodium levels.
