The nurse is providing care for a client with a fluid imbalance. The nurse explains that in the body, areas with high concentration of solutes naturally and passively shift to areas of lower concentration. The nurse is describing which process?

Choice A reason: This is not a correct finding for hypovolemia. Peripheral edema is the swelling of the extremities due to fluid accumulation in the interstitial spaces. It is a sign of fluid volume excess, not fluid volume deficit.

Choice B reason: This is not a correct finding for hypovolemia. Bradycardia is a slow heart rate, usually below 60 beats per minute. It is not a typical sign of fluid volume deficit, as the heart rate usually increases to compensate for the low blood pressure and low cardiac output.

Choice C reason: This is not a correct finding for hypovolemia. Hypertension is a high blood pressure, usually above 140/90 mmHg. It is not a typical sign of fluid volume deficit, as the blood pressure usually decreases due to the reduced blood volume and vascular resistance.

Choice D reason: This is a correct finding for hypovolemia. Decreased urine output is a sign of fluid volume deficit, as the kidneys try to conserve water and electrolytes by reducing the urine production. The normal urine output is about 30 mL per hour, and anything below 20 mL per hour is considered oliguria, which indicates impaired renal function.

Choice A reason: The client quitting smoking 6 months ago is not a factor that would exclude her from being an appropriate surgical candidate. In fact, smoking cessation is a requirement for bariatric surgery, as smoking increases the risk of complications such as infection, thrombosis, and poor wound healing.

Choice B reason: The client having a strong family history of obesity is not a factor that would exclude her from being an appropriate surgical candidate. Family history is one of the genetic factors that can contribute to obesity, but it does not determine the eligibility for bariatric surgery. Other factors such as BMI, comorbidities, lifestyle, and motivation are more important.

Choice C reason: The client drinking six to eight cans of beer daily is a factor that would exclude her from being an appropriate surgical candidate. Alcohol abuse is a contraindication for bariatric surgery, as it can cause liver damage, malnutrition, dehydration, and addiction transfer. The client would need to abstain from alcohol for at least 6 months before and after the surgery.

Choice D reason: The client having poorly controlled type 2 diabetes is not a factor that would exclude her from being an appropriate surgical candidate. Type 2 diabetes is one of the comorbidities that can qualify a client for bariatric surgery, as it can improve or resolve after the surgery. However, the client would need to have a good glycemic control before the surgery to reduce the risk of complications.
