A nurse is providing teaching to a client who has diabetes mellitus about carbohydrate intake needs when exercising. Which of the following foods should the nurse include as containing a 15 g serving of carbohydrates?

Order a high-fiber diet

Choice A Reason:

Encourage dietary intake

Encouraging dietary intake is generally important for maintaining nutritional status, but it is not specific to the preparation for a barium enema. The preparation for a barium enema typically involves dietary restrictions to ensure the colon is clear for the procedure. Therefore, this choice is not correct.

Choice B Reason:

Encourage plenty of fat

Encouraging plenty of fat is not appropriate for the preparation of a barium enema. High-fat foods can slow down the digestive process and may interfere with the clarity of the images obtained during the procedure. Therefore, this choice is not correct.

Choice C Reason:

Serve dairy products

Serving dairy products is not recommended before a barium enema. Dairy products can cause gas and bloating, which can interfere with the procedure. Additionally, some patients may be lactose intolerant, which can further complicate the preparation. Therefore, this choice is not correct.

Choice D Reason:

Order a high-fiber diet

Ordering a high-fiber diet is the correct choice. A high-fiber diet helps to clear the intestines by promoting bowel movements. This is important for ensuring that the colon is empty and clear for the barium enema, which allows for better imaging and more accurate results.

Choice A: Increased Respiratory Rate

Fluid overload, also known as hypervolemia, can lead to an increased respiratory rate. This occurs because the excess fluid in the body can accumulate in the lungs, leading to pulmonary congestion and edema. As a result, the body attempts to compensate by increasing the respiratory rate to improve oxygenation and remove excess carbon dioxide. Normal respiratory rate for adults is typically between 12-20 breaths per minute. An increased respiratory rate above this range can indicate fluid overload.

Choice B: Increased Heart Rate

An increased heart rate, or tachycardia, is another common finding in clients with fluid overload. The heart has to work harder to pump the excess fluid throughout the body, leading to an increased heart rate. This is a compensatory mechanism to maintain adequate cardiac output and tissue perfusion. Normal resting heart rate for adults is between 60-100 beats per minute. A heart rate above this range can be indicative of fluid overload.

Choice C: Increased Blood Pressure

Fluid overload can also result in increased blood pressure, or hypertension. The excess fluid in the bloodstream increases the volume of blood that the heart has to pump, leading to higher pressure within the arteries. This can strain the cardiovascular system and lead to complications if not managed properly. Normal blood pressure is typically around 120/80 mmHg. Blood pressure readings consistently above this range can suggest fluid overload.

Choice D: Increased Hematocrit

Increased hematocrit is not typically associated with fluid overload. Hematocrit is the proportion of red blood cells in the blood. In cases of fluid overload, the hematocrit level is usually decreased due to the dilutional effect of the excess fluid. Therefore, this choice is incorrect.

Choice E: Increased Temperature

Increased temperature is not a common finding in fluid overload. Fever or elevated body temperature is more commonly associated with infections or inflammatory conditions. Fluid overload does not typically cause an increase in body temperature. Therefore, this choice is incorrect.
