Correct Answer is B

Explanation

A. "My breath may have a fruity odor." is incorrect. While fruity breath odor can occur with diabetic ketoacidosis (DKA), it is not a common early sign of hyperglycemia in general.

B. "I will be more thirsty than usual." is correct. Polydipsia (excessive thirst) is a hallmark symptom of hyperglycemia due to the body's attempt to compensate for increased blood glucose levels by drawing water out of cells, leading to dehydration.

C. "I might experience blurry vision at times." is incorrect. While blurry vision can occur due to fluid shifts in the lens caused by hyperglycemia, polydipsia is a more definitive and consistent early sign.

D. "My appetite will be decreased." is incorrect. Polyphagia (increased appetite) is a common symptom of hyperglycemia, not decreased appetite. This occurs because glucose is not properly entering the cells for energy, leading to increased hunger.

Correct Answer is ["2"]

Explanation

To calculate the number of tablets to administer, we'll use the following formula:

Number of tablets = Desired dose (mcg) / Tablet strength (mcg)

In this case:

  • Desired dose = 100 mcg
  • Tablet strength = 50 mcg

Plugging the values into the formula:

  • Number of tablets = 100 mcg / 50 mcg = 2 tablets
