Fluid and electrolyte balance is maintained through the process of fluid and solutes moving in and out of cells. What specific process allows fluid to pass through a membrane from a dilute to a more concentrated area?

Choice A reason: Normal saline is not contraindicated for a dehydrated client with a skull fracture. Normal saline is an isotonic solution that has the same concentration of solutes as the blood plasma. It can help restore fluid balance and prevent cerebral edema.

Choice B reason: Dextrose in water 5% is contraindicated for a dehydrated client with a skull fracture. Dextrose in water 5% is a hypotonic solution that has a lower concentration of solutes than the blood plasma. It can cause fluid to shift from the blood vessels into the brain cells, increasing the intracranial pressure and worsening the skull fracture.

Choice C reason: Lactated Ringer's (LR) is not contraindicated for a dehydrated client with a skull fracture. Lactated Ringer's (LR) is an isotonic solution that has the same concentration of solutes as the blood plasma. It can also provide electrolytes such as sodium, potassium, calcium, and lactate, which can help correct acid-base imbalances.

Choice D reason: Dextrose in normal saline is not contraindicated for a dehydrated client with a skull fracture. Dextrose in normal saline is a hypertonic solution that has a higher concentration of solutes than the blood plasma. It can cause fluid to shift from the brain cells into the blood vessels, reducing the intracranial pressure and cerebral edema.

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.
