A nurse is preparing to mix a dose of NPH insulin and regular insulin into a single syringe. Which of the following actions should the nurse take first?
Withdraw dose of regular insulin.
Inject air into the vial of regular insulin.
Inject air into the vial of NPH insulin.
Withdraw dose of NPH insulin.
The Correct Answer is C
A. Withdraw dose of regular insulin: Withdrawing the regular insulin dose is performed after the air has been injected into both vials and the NPH insulin has been drawn up if using the “clear before cloudy” technique. Doing this first would risk disrupting the proper sequence and potentially contaminating the insulin.
B. Inject air into the vial of regular insulin: Air must be injected into the regular insulin vial before withdrawing the medication, but this step is performed after first injecting air into the NPH vial according to the standard procedure for mixing insulins. Starting with the regular insulin vial would not follow the recommended order.
C. Inject air into the vial of NPH insulin: Injecting air into the NPH insulin vial first is the initial step when preparing a mixed insulin dose. This step equalizes pressure inside the vial, allowing for easier withdrawal later, and follows the correct sequence of “air into cloudy first, then clear,” which prevents contamination of the regular insulin.
D. Withdraw dose of NPH insulin: Withdrawing NPH insulin is done after the regular insulin has been drawn into the syringe to maintain the correct “clear before cloudy” technique. Doing this first could result in accidental mixing or contamination of the regular insulin.

Correct Answer is ["A","C"]
Explanation
A. Allow extra time for the client to perform tasks: Clients with vision loss may require additional time to navigate their environment and complete activities safely. Providing extra time reduces stress, supports independence, and promotes a sense of autonomy while performing daily tasks.
B. Touch the client gently to announce presence: The nurse should announce presence verbally first. Touching without warning may startle the client.
C. Keep objects in the client's room in the same place: Maintaining a consistent arrangement of personal items prevents confusion and reduces the risk of falls or accidents. Predictable placement allows the client to perform tasks safely and maintain independence.
D. Approach the client from the side: Approaching from the side is not recommended because it may startle the client. Best practice is to approach from the front while using verbal cues to announce your presence and provide orientation.
E. Ensure there is high-wattage lighting in the client's room: High-intensity lighting may cause glare and discomfort for clients with vision loss, especially those with conditions like macular degeneration. Adequate but non-glare lighting is preferable to support safe mobility.
Correct Answer is A
Explanation
A. Implement firm but flexible boundaries in their relationship: Establishing boundaries helps both the client and adult child adapt to new caregiving roles while maintaining mutual respect and autonomy. Flexibility allows for adjustments as the client’s needs change, reducing role strain and promoting a healthy family dynamic.
B. Encourage authoritative communication from the adult child: While clear communication is important, an authoritative style may be perceived as controlling and can create tension. Collaborative, respectful communication is more effective in supporting role adjustment and maintaining family harmony.
C. Decrease socialization with extended relatives until roles are identified: Limiting social interactions is unnecessary and may increase isolation or stress. Maintaining connections with extended family can provide emotional support and resources during the transition.
D. Minimize open discussion regarding the changes to avoid embarrassment: Avoiding discussion about changes can lead to misunderstandings, unmet needs, and emotional strain. Open, honest communication helps clarify expectations, reduce conflict, and facilitate adjustment to new roles.
