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 The nurse must inject the corresponding amount of air for the dose needed, ensuring that the insulin can be withdrawn smoothly and accurately without bubbles, which could affect the dose.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.

Explanation
The nurse should expect to find hyperkalemia in the medical record of a client who has sustained a full- thickness burn and is in the emergent phase of the burn. This is due to the release of potassium from damaged cells into the bloodstream.
a) Hypernatremia is not a common finding in the emergent phase of a burn.
b) Hypercalcemia is not a common finding in the emergent phase of a burn.
c) Hypermagnesemia is not a common finding in the emergent phase of a burn.
Correct Answer is D
Explanation
Grapes are a common choking hazard for young children, especially toddlers, due to their small size, round shape, and slippery texture. The size and shape of grapes can block the airway and pose a significant risk if not properly cut or prepared before being given to a toddler. It is recommended to cut grapes into small pieces or slice them lengthwise to reduce the risk of choking.
While potatoes, corn, and oranges can also pose a choking risk if not properly prepared or cut into age-appropriate sizes, they are not as commonly associated with choking incidents in toddlers as grapes are. Nonetheless, it is essential for parents and caregivers to be aware of appropriate food preparation techniques and supervise children during meals to ensure their safety.
