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: Constipation is not a priority finding for a client with peptic ulcer disease. It may be a side effect of some medications or a result of decreased fluid intake, but it does not indicate a serious complication.

Choice B reason: Dyspepsia is a common symptom of peptic ulcer disease, but it is not a priority finding. It refers to indigestion or discomfort in the upper abdomen, which may be relieved by antacids or other medications.

Choice C reason: Hematemesis is a priority finding for a client with peptic ulcer disease. It indicates bleeding from the ulcer, which can lead to shock and anemia. The nurse should monitor the client's vital signs, hemoglobin level, and blood loss, and notify the provider immediately.

Choice D reason: Epigastric discomfort is another common symptom of peptic ulcer disease, but it is not a priority finding. It refers to pain or burning in the upper abdomen, which may be worsened by food intake or stress. The nurse should provide comfort measures and educate the client on dietary and lifestyle modifications.

Choice A reason: An obese client whose parents and siblings are not obese may have obesity due to environmental or behavioral factors, such as diet, physical activity, or stress. Medication may not be effective for this type of obesity, and lifestyle changes may be more appropriate.

Choice B reason: A client with long-standing obesity who has recently been diagnosed with type 2 diabetes may have obesity due to insulin resistance, which impairs the body's ability to use glucose and increases fat storage. Medication may help with glucose control, but it may not resolve the obesity. The client may also need to follow a diabetic diet and exercise regimen.

Choice C reason: A client whose obesity has been attributed to a reversible endocrine disorder like hypothyroidism may have obesity due to hormonal imbalance, which affects the metabolism and energy expenditure. Medication may be effective for this type of obesity, as it can restore the normal function of the thyroid gland and increase the metabolic rate.

Choice D reason: A client whose obesity is characterized as android rather than gynoid may have obesity due to genetic or gender factors, such as the distribution of fat in the upper body or the influence of male hormones. Medication may not be effective for this type of obesity, and the client may benefit from other interventions such as surgery or counseling.
