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 The nurse must inject the corresponding amount of air for the dose needed, ensuring that the insulin can be withdrawn smoothly and accurately without bubbles, which could affect the dose.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 ."I will take a stool softener to prevent constipation."
Explanation:
The statement that indicates an understanding of the instructions is "I will take a stool softener to prevent constipation."
Explanation for the other options:
b. "I will ask to work the night shift, so I will not be driving in bright sunlight."
This statement is incorrect. The need to work the night shift to avoid bright sunlight does not relate to the discharge instructions for a client postoperative following laser surgery for open-angle glaucoma. The primary focus of discharge teaching for this condition would be related to eye care, medication administration, and follow-up appointments.
c. "I will need to use my eye drops for 1 year."
This statement is incorrect. While eye drops are commonly prescribed for open-angle glaucoma, the duration of their use can vary based on the individual's condition and the healthcare provider's instructions. The client should follow the specific instructions given by their healthcare provider regarding the frequency and duration of eye drop use.
d. "I will need to follow a low-protein diet."
This statement is incorrect. A low-protein diet is not typically part of the discharge instructions for a client postoperative following laser surgery for open-angle glaucoma. The focus of dietary recommendations for open-angle glaucoma is on maintaining a healthy diet and managing other health conditions that may affect intraocular pressure, such as high blood pressure or diabetes.
In summary, the statement that demonstrates an understanding of the discharge instructions for a client postoperative following laser surgery for open-angle glaucoma is "I will take a stool softener to prevent constipation." This indicates the client's awareness of the importance of preventing constipation, which can be a side effect of some medications prescribed after surgery.
Correct Answer is A
Explanation
Answer: A. Apply light pressure to the inner canthus just after instilling the eye drops.
Rationale:
A) Apply light pressure to the inner canthus just after instilling the eye drops.
Applying pressure to the inner canthus (the corner of the eye nearest the nose) helps occlude the nasolacrimal duct. This action reduces the systemic absorption of the medication by preventing it from draining into the nasal passages and subsequently into the systemic circulation, thus enhancing the local effect of the eye drops.
B) Wipe the eye from the inner to the outer canthus with a sterile saline-moistened cotton ball.
While this action may help remove excess medication or discharge, it does not minimize systemic absorption. Instead, wiping the eye could inadvertently spread the medication to other areas, increasing the chance of absorption rather than reducing it.
C) Administer the medication drops directly into the lower conjunctival sac of each eye.
While placing drops in the lower conjunctival sac is a standard practice for delivering ophthalmic medications, it does not directly influence systemic absorption. The main goal is to ensure adequate dosing in the eye, but systemic absorption can still occur if the drops drain into the nasolacrimal duct.
D) Wait 5 min after instillation before instilling the drops in the other eye.
Waiting between instillations is good practice to prevent dilution of the first dose and to allow for absorption. However, this action does not significantly impact systemic absorption. It focuses more on ensuring that the first dose is effective before administering a second dose.
