A nurse is providing discharge teaching to a client who has hypocalcemia. Which of the following statements by the client indicates understanding of the teaching?

A. "This lab measures your average blood glucose over a 3-month period." The hemoglobin A1c test reflects the average blood glucose levels over the past 2 to 3 months by measuring the percentage of glucose attached to hemoglobin in red blood cells. Since red blood cells have a lifespan of about 120 days, this test provides a long-term view of glycemic control.
B. "An increase in your hemoglobin A1c level indicates glycemic control." An increase in hemoglobin A1c levels actually indicates poor glycemic control, not improvement. Higher values mean blood glucose has been elevated over time, which can lead to complications such as neuropathy, nephropathy, and retinopathy in diabetic patients.
C. "This lab value is a good indicator of short-term nutritional status." The hemoglobin A1c test is not used to assess short-term nutritional status. Instead, it measures long-term blood glucose trends. For evaluating short-term changes in nutrition, blood glucose logs or postprandial glucose readings are better tools to use.
D. "You will need to fast before getting this test." Fasting is not required for the hemoglobin A1c test. The result is not affected by recent food intake, making it convenient for patients. This feature makes it more practical than fasting plasma glucose or oral glucose tolerance tests when assessing overall glycemic control in diabetes management.

A. Cheese: Cheese is a developmental and nutritious snack for a 30-month-old toddler. It provides essential nutrients such as calcium and protein, which support bone development and growth. Cheese is also soft in texture and easy to chew, minimizing the risk of choking. Additionally, it can be cut into small, manageable pieces that are safe for toddlers to eat independently.
B. Grapes: Whole grapes are a choking hazard for children under the age of 4 due to their round shape and slippery texture. Even though they are nutritious, they should be cut into small, lengthwise pieces before offering them to toddlers. Offering whole grapes to a 30-month-old toddler puts the child at significant risk of aspiration or airway obstruction.
C. Plain popcorn: Popcorn is not safe for toddlers because it poses a high risk of choking. Its texture can be difficult for young children to chew thoroughly, and unpopped kernels or sharp edges can block or irritate the airway. Health authorities recommend avoiding popcorn until children are older and can chew food more effectively.
D. Raw carrots: Raw carrots are firm and hard to chew, making them a common choking hazard for toddlers. Unless they are cooked until soft or grated finely, they should not be given to young children. A 30-month-old toddler may not yet have the molar teeth or chewing coordination needed to handle raw vegetables safely.
