A nurse is teaching an older adult client about vitamin D deficiency. The nurse should encourage the client to consume an adequate amount of vitamin D to prevent which of the following complications?

Choice A reason: Providing a snack 30 min before treatments can worsen nausea and diarrhea, as food can stimulate gastric motility and secretion. It is better to avoid eating for at least 2 hours before and after treatments.

Choice B reason: Ensuring foods are served hot can increase nausea and diarrhea, as hot foods can have strong smells and irritate the digestive tract. It is better to serve foods at room temperature or cold.

Choice C reason: Administering antiemetics on a schedule can prevent nausea and vomiting, which can lead to dehydration and electrolyte imbalance. Antiemetics can also reduce abdominal cramps and spasms that cause diarrhea.

Choice D reason: Serving low carbohydrate meals can aggravate diarrhea, as carbohydrates are the main source of energy for the body. It is better to serve high carbohydrate meals that are easy to digest, such as rice, potatoes, bread, or crackers.

Choice A reason: Checking blood glucose level is an appropriate action for the nurse to take because it can help determine if the client has hypoglycemia or hyperglycemia, which are both complications of diabetes mellitus that can cause dizziness and weakness. Blood glucose level should be checked using a glucometer and compared with the normal range of 70 to 130 mg/dL before meals and less than 180 mg/dL after meals.

Choice B reason: Giving insulin injection is not an appropriate action for the nurse to take without checking blood glucose level first because it may cause hypoglycemia, which is a condition in which blood glucose level drops below 70 mg/dL and can cause dizziness, weakness, confusion, sweating, and seizures. Insulin injection should be given according to the prescribed dose, type, and schedule.

Choice C reason: Offering orange juice is not an appropriate action for the nurse to take without checking blood glucose level first because it may cause hyperglycemia, which is a condition in which blood glucose level rises above 180 mg/dL and can cause dizziness, weakness, thirst, polyuria, and ketoacidosis. Orange juice should be offered only if the client has hypoglycemia and is conscious and able to swallow.

Choice D reason: Applying cold compress is not an appropriate action for the nurse to take because it does not address the underlying cause of dizziness and weakness in a client who has diabetes mellitus. Cold compress may worsen the symptoms by reducing blood flow and oxygen delivery to the brain. Cold compress should be applied only if the client has fever, inflammation, or pain.
