A nurse is caring for a client who has gastroenteritis and is reviewing the client's findings from two days ago and today. Which of the following findings require immediate follow-up?

Choice A reason: Reducing caloric intake by 200 calories a day may not be enough to achieve significant weight loss for a client who is obese. The recommended daily calorie deficit for weight loss is 500 to 750 calories, which can result in a loss of 1 to 1.5 pounds per week¹.

Choice B reason: Losing 5 percent of body weight can improve glycemic control and reduce the need for glucose-lowering medications for a client who has type 2 diabetes. Studies have shown that weight loss of 5 to 10 percent can lower HbA1c levels by 0.5 to 1.0 percentage points².

Choice C reason: Exercising for 30 minutes three times a week may not be sufficient to lose 1 pound per week. The recommended amount of physical activity for weight loss is at least 150 minutes of moderate-intensity aerobic exercise per week, plus resistance training at least twice a week³.

Choice D reason: Drinking 16 ounces of apple juice is not advisable if the blood glucose level drops during exercise, as it can cause hyperglycemia. Apple juice contains about 48 grams of carbohydrates, which is equivalent to four servings of glucose tablets⁴. The recommended treatment for hypoglycemia is to consume 15 to 20 grams of fast-acting carbohydrates, such as glucose tablets, gel, or juice, and recheck the blood glucose level after 15 minutes⁵.

Choice A reason: Elastic skin turgor is a sign of adequate hydration and fluid balance. Skin turgor is the ability of the skin to return to its normal shape after being pinched or pulled. When the skin is dehydrated, it loses its elasticity and becomes tented or wrinkled. The nurse should assess the skin turgor on the chest, abdomen, or forehead, and not on the hands or feet, which can be affected by aging or edema.

Choice B reason: Dry mucous membranes are a sign of fluid volume deficit, not fluid volume excess. Mucous membranes are the moist linings of the mouth, nose, eyes, and other body openings. When the body is dehydrated, the mucous membranes become dry, cracked, or sticky. The nurse should assess the mucous membranes for color, moisture, and capillary refill.

Choice C reason: Oliguria is a sign of fluid volume deficit, not fluid volume excess. Oliguria is the production of abnormally small amounts of urine, usually less than 400 mL per day or 30 mL per hour. Oliguria can indicate reduced kidney function, impaired blood flow to the kidneys, or inadequate fluid intake. The nurse should monitor the urine output, color, specific gravity, and presence of blood or protein.

Choice D reason: Tachycardia is a sign of fluid volume deficit, not fluid volume excess. Tachycardia is a rapid heart rate, usually more than 100 beats per minute. Tachycardia can occur when the body is dehydrated, as the heart tries to pump more blood to maintain the blood pressure and perfusion. The nurse should measure the pulse rate, rhythm, quality, and amplitude.
