A nurse on a medical-surgical unit knows that for clients with a BMI greater than or equal to 30, it is important to:

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: Utilize supine positioning to maximize chest expansion is not an important intervention for clients with a BMI greater than or equal to 30. Supine positioning is when the client lies flat on their back. This position can actually impair chest expansion and breathing for clients with a high BMI, as the weight of the abdomen and chest can compress the lungs and diaphragm. A semi-Fowler's position, where the head of the bed is elevated at 30 to 45 degrees, is preferred for these clients, as it reduces the pressure on the chest and improves ventilation.

Choice B reason: Use an appropriately sized blood pressure cuff is an important intervention for clients with a BMI greater than or equal to 30. A blood pressure cuff that is too small or too tight can cause inaccurate readings and increase the risk of injury to the client. A blood pressure cuff that is too large or too loose can also cause inaccurate readings and compromise the quality of care. A blood pressure cuff that fits the client's arm circumference and width is essential for obtaining accurate and reliable measurements and preventing complications.

Choice C reason: Consult a nutritionist because the client is malnourished/underweight is not an important intervention for clients with a BMI greater than or equal to 30. A BMI greater than or equal to 30 indicates that the client is obese, not malnourished or underweight. Obesity is a condition where the client has excess body fat that can affect their health and well-being. Malnutrition is a condition where the client has inadequate or imbalanced intake of nutrients that can affect their growth and development. Underweight is a condition where the client has a low body weight that can affect their immunity and energy. A nutritionist can help clients with any of these conditions, but the statement is incorrect for clients with a high BMI.

Choice D reason: Place the client on fall precautions because of increased risk for falls due to frail bones is not an important intervention for clients with a BMI greater than or equal to 30. Frail bones are not a common consequence of obesity, but rather of osteoporosis, a condition where the bones become weak and brittle. Obesity can actually increase the bone density and strength, as the bones have to support more weight. However, obesity can increase the risk for falls due to other factors, such as impaired mobility, balance, or coordination. Fall precautions are important for any client who is at risk for falls, but the statement is inaccurate for clients with a high BMI.
