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 The nurse must inject the corresponding amount of air for the dose needed, ensuring that the insulin can be withdrawn smoothly and accurately without bubbles, which could affect the dose.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 D
Explanation
d. Increased joint stiffness due to loss of elasticity in joint cartilage.
Explanation:
The correct answer is d. Increased joint stiffness due to loss of elasticity in joint cartilage.
When teaching an older adult client about age-related changes, it is important for the nurse to provide accurate and relevant information. Joint stiffness is a commonly experienced age-related change that occurs due to the natural loss of elasticity in joint cartilage. As people age, their joints may become stiffer and less flexible, making movements and activities more challenging.
Option a is not the correct answer. Increased nail growth due to the buildup of calcium deposits is not an expected age-related change. Nail growth is primarily determined by factors such as genetics, overall health, and nutritional status, rather than calcium deposits.
Option b is not the correct answer. Increased perspiration due to overproduction by the sweat glands is not an expected age-related change. In fact, older adults may experience a decrease in the production of sweat, which can make them more susceptible to heat-related illnesses and dehydration.
Option c is not the correct answer. Increased cardiac output due to weakened heart walls is not an expected age-related change. With aging, the heart muscles may become stiffer and less efficient, leading to a decrease in cardiac output rather than an increase.
By focusing on the expected age-related change of increased joint stiffness due to loss of elasticity in joint cartilage, the nurse can provide accurate information and help the older adult client understand and manage this common aspect of the aging process.
