A client who is 12 weeks pregnant has type 1 diabetes mellitus. Which instruction should the nurse provide related to insulin dosages?
Fluctuate from 24 weeks to approximately 36 weeks of gestation.
Increases from 18 weeks to approximately 36 weeks of gestation.
May double or quadruple during the second trimester.
Remain stable until delivery, then increase after delivery.
The Correct Answer is B
Rationale:
A. Insulin requirements generally increase as pregnancy progresses due to the growing placenta and hormones that cause insulin resistance, not fluctuate significantly.
B. Insulin requirements typically begin to increase around 18 weeks of gestation and continue to rise until approximately 36 weeks due to increased insulin resistance caused by placental hormones.
C. While insulin needs do increase, they do not typically double or quadruple during the second trimester. The increase is more gradual.
D. Insulin requirements increase during pregnancy and may decrease after delivery as the placenta is no longer present, removing the source of insulin resistance.

Correct Answer is D
Explanation
Rationale:
A. Urinary output is important but not as critical as identifying the potential source of infection.
B. A 24-hour medication history is useful but secondary to identifying an acute infection.
C. The amount of serous drainage provides information on wound healing but does not confirm infection.
D. Increased confusion in an older adult, especially with a wound present, raises concern for infection, possibly sepsis. A WBC count can help identify infection and guide further treatment.
Correct Answer is A
Explanation
Rationale:
A. Administering insulin per sliding scale is appropriate for managing elevated blood glucose in a patient who is NPO and cannot take oral hypoglycemics like metformin.
B. Repeating the test in one hour delays necessary treatment and does not address the current hyperglycemia.
C. A continuous IV infusion of insulin is more appropriate for severe hyperglycemia or critical care situations, but obtaining a sliding scale prescription is more routine in this context.
D. Administering metformin with a sip of water could be considered if the provider orders it, but typically, oral hypoglycemics are held when a patient is NPO.
