A nurse is providing teaching for a client who has diabetes mellitus about the self-administration of insulin. The client has prescriptions for regular and NPH insulins. Which of the following statements by the client indicates an understanding of the teaching?
"I will draw the regular insulin into the syringe first."
"I will store prefilled syringes in the refrigerator with the needle pointed upward."
"I will gently roll the NPH vial between my hands before drawing up the insulin."
"I will insert the needle at a 90-degree angle."
The Correct Answer is A
Choice A reason: Drawing the regular insulin into the syringe first is correct. When mixing two types of insulin, the clear (regular) insulin should be drawn up before the cloudy (NPH) insulin to prevent contamination.
Choice B reason: Storing prefilled syringes with the needle pointed upward can cause air bubbles to move into the insulin, which can alter the dose when injected. The needle should be pointed downward.
Choice C reason: Shaking the NPH vial vigorously is not recommended as it can create air bubbles and affect the insulin dose. Instead, the vial should be gently rolled between the hands to mix the insulin.
Choice D reason: Inserting the needle at a 15-degree angle is incorrect for subcutaneous injections. A 90-degree angle is typically used unless the patient is very thin, in which case a 45-degree angle may be used.

Correct Answer is ["8.3"]
Explanation
Step 1: Total volume = 1000 mL (which is 1 liter)
Step 2: Total time = 2 hours. But since the infusion pump rate is typically set in mL per minute, we need to convert this to minutes. There are 60 minutes in an hour, so 2 hours is 2 × 60 = 120 minutes.
Step 3: Now we can calculate the rate. The rate is the total volume divided by the total time. So, the rate = 1000 mL ÷ 120 minutes.
Calculating the above gives us the rate at which the nurse will set the infusion pump. Let's calculate it:
Step 4: Rate = 1000 mL ÷ 120 minutes = 8.33 mL/minute.
So, the nurse will set the infusion pump at a rate of approximately 8.33 mL per minute. If rounding is required, this can be rounded to 8.3 mL per minute.
Correct Answer is B
Explanation
Choice A reason: Instructing the client to avoid eating raw vegetables may be a precautionary measure due to potential immunosuppression from AIDS, but it does not directly demonstrate advocacy. Advocacy would involve actions that support the client's rights, choices, and interests, and while dietary advice is important, it is not an advocacy action in itself.
Choice B reason: Initiating a referral for the client to a home health agency is a clear demonstration of client advocacy. This action shows that the nurse is taking steps to ensure the client receives the necessary support to manage their condition at home, respecting their wish to maintain independence and quality of life.
Choice C reason: Reminding the client of the importance of medication adherence is part of the nurse's educational role but does not necessarily reflect advocacy. Advocacy would involve more proactive measures to support the client's treatment and care decisions.
Choice D reason: Telling the client to avoid places where there are large crowds of people is good advice to reduce the risk of infections, but it is not an advocacy action. Advocacy involves representing the client's interests and facilitating their choices and access to care.
