A nurse is preparing to administer 5 units of regular insulin and 20 units of NPH insulin to a client who has type 1 diabetes mellitus. Which of the following actions should the nurse take first?
Inject 20 units of air into the vial of NPH insulin.
Inject 5 units of air into the vial of regular insulin.
Withdraw 20 units of NPH insulin from the vial.
Withdraw 5 units of regular insulin from the vial.
The Correct Answer is A
Answer: (A) Inject 20 units of air into the vial of NPH insulin.
Rationale:
A) Inject 20 units of air into the vial of NPH insulin:
Injecting air into the vial of NPH insulin is the first step to prevent creating a vacuum, which could make it difficult to withdraw the insulin later. The nurse must inject the corresponding amount of air for the dose needed, ensuring that the insulin can be withdrawn smoothly and accurately without bubbles, which could affect the dose.
B) Inject 5 units of air into the vial of regular insulin:
Injecting air into the regular insulin vial is also necessary before withdrawing the insulin, but it should be done after injecting air into the NPH vial. This sequence ensures that no NPH insulin contaminates the regular insulin vial when the nurse withdraws the doses later.
C) Withdraw 20 units of NPH insulin from the vial:
Withdrawing NPH insulin should be done after air is injected into both vials and after the regular insulin has been drawn up. This sequence prevents the mixing of the two types of insulin and ensures accurate dosing, which is crucial for maintaining the correct blood glucose levels.
D) Withdraw 5 units of regular insulin from the vial:
Withdrawing regular insulin is critical to do before the NPH insulin to prevent contamination of the regular insulin with NPH, which could alter the onset and peak times of the regular insulin. However, it should follow the steps of injecting air into both vials, starting with the NPH vial.

Correct Answer is A
Explanation
A nurse caring for a client who is receiving total parenteral nutrition should identify that a serum calcium level of 12.5 mg/dL indicates a possible complication of this therapy. Total parenteral nutrition can result in electrolyte imbalances, including hypercalcemia (high levels of calcium in the blood).
The other laboratory results are within normal ranges and do not indicate a complication of total parenteral nutrition.
b) A BUN level of 16 mg/dL is within the normal range.
c) A serum potassium level of 4.6 mEq/L is within the normal range.
d) A WBC count of 8,000/mm³ is within the normal range.
Correct Answer is D
Explanation
When a mother states that she should have her baby latch on to both the nipple and areola during breastfeeding, it demonstrates an understanding of the correct latch technique. A proper latch involves the baby taking in not just the nipple but also a portion of the surrounding areola. This ensures effective milk transfer and helps prevent nipple soreness or damage.
"My baby should breastfeed 5 to 10 minutes on each breast": This statement is not entirely accurate. It is important to understand that breastfeeding duration can vary among infants, and there is no fixed timeframe for how long a baby should breastfeed on each breast. Some infants
may nurse for shorter periods, while others may take longer. The focus should be on ensuring that the baby is effectively nursing and getting enough milk rather than adhering strictly to a specific time limit.
"I should keep my baby on a strict feeding schedule": This statement is incorrect. Breastfeeding on demand, also known as responsive feeding, is generally recommended for newborns.
Newborns should be fed whenever they show signs of hunger, such as rooting, sucking motions, or increased alertness. Strict feeding schedules can interfere with the baby's natural feeding cues and hinder milk supply establishment.
"I should not wake my baby during the night to breastfeed": This statement is not accurate, especially for a 5-day-old newborn. Newborns typically need frequent feeding, including during the night, to meet their nutritional needs and support proper growth and development. It is generally recommended to wake a sleeping newborn every 2-3 hours during the night to ensure adequate feeding and prevent excessive weight loss.
