A nurse in a long-term care facility is collecting data from an older adult client. Which of the following findings indicates that the client might be dehydrated?

Choice A reason: Taking the medication right before eating breakfast is not an appropriate instruction, as it can reduce the absorption and effectiveness of alendronate, which is a bisphosphonate drug that inhibits bone resorption and increases bone density. The client should take the medication at least 30 min before eating or drinking anything other than water.

Choice B reason: Drinking milk with the medication is not an appropriate instruction, as it can interfere with the absorption and effectiveness of alendronate, which can bind to calcium and other minerals and form insoluble complexes that are excreted in feces. The client should avoid consuming dairy products or supplements that contain calcium, iron, magnesium, or aluminum for at least 30 min after taking the medication.

Choice C reason: Staying upright for 30 to 60 min after taking the medication is an appropriate instruction, as it can prevent esophageal irritation or ulceration that can be caused by alendronate, which can be corrosive to the mucosa if it remains in contact with it for too long. The client should not lie down or bend over until after their first food of the day.

Choice D reason: Chewing the tablets thoroughly is not an appropriate instruction, as it can increase the risk of esophageal irritation or ulceration that can be caused by alendronate, which can be abrasive to the mucosa if it is not swallowed whole with a full glass of water. The client should not crush, break, or dissolve the tablets in any liquid.

Choice A reason: HbA1c or glycated hemoglobin is a measure of average blood glucose levels over the past 2 to 3 months. A lower HbA1c indicates better glycemic control and a lower risk of diabetes complications. The target HbA1c for most people with diabetes mellitus is less than 7%.

Choice B reason: HbA1c 12.5% is very high and indicates poor glycemic control and a high risk of diabetes complications, such as retinopathy, nephropathy, or neuropathy.

Choice C reason: Fasting blood glucose 100 mg/dL is within the normal range of 70 to 99 mg/dL and indicates normal glucose metabolism, but it does not reflect the long-term control of blood glucose levels over the past 3 months.

Choice D reason: Fasting blood glucose 70 mg/dL is at the lower end of the normal range and may indicate hypoglycemia or low blood glucose levels, which can cause symptoms such as sweating, trembling, hunger, or confusion.
