A client comes to a primary care provider's office for a follow-up on their gastroesophageal reflux disease (GERD). The provider has decided to screen the client for Barrett esophagus due to the patient struggling with symptoms for many years. The nurse should provide instruction on which diagnostic procedure?

Choice A reason: Slowing the rate to 50 mL/hr is not an appropriate action by the nurse before calling the physician to clarify the order. This could cause the client to become more hypovolemic, which is a condition where there is a decreased volume of blood in the body. Hypovolemia can lead to shock, organ failure, and death.

Choice B reason: Slowing the rate to 20 mL/hr is not an appropriate action by the nurse before calling the physician to clarify the order. This could also cause the client to become more hypovolemic, which is a serious and life-threatening condition. The nurse should not reduce the IV fluid rate without a physician's order.

Choice C reason: Increasing the rate to 250 mL/hr is not an appropriate action by the nurse before calling the physician to clarify the order. This could cause the client to become more hypervolemic, which is a condition where there is an excess of fluid in the blood vessels. Hypervolemia can cause fluid overload, pulmonary edema, and heart failure.

Choice D reason: Continuing the rate at 125 mL/hr is an appropriate action by the nurse before calling the physician to clarify the order. This is a reasonable rate for a client who has a head injury and hypovolemia, as it can help restore the fluid balance and prevent cerebral edema. The nurse should not change the IV fluid rate without a physician's order.

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.
