(Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Question 2 of 5
A nurse is caring for a client who is prescribed 15 units of NPH insulin to be administered at 0700. At which of the following times of day is most appropriate for the nurse to plan to offer a snack?

Correct Answer: D
Rationale: Thyroid stimulating hormone (TSH) is suppressed in hyperthyroidism because the thyroid gland produces excessive hormones, causing a negative feedback loop that reduces TSH levels.
