A nurse is preparing to instill an otic suspension into an adult client's ear.

Which of the following methods should the nurse plan to use?

Compartment syndrome is a condition characterized by increased pressure within a closed anatomical space, such as a compartment in the leg. This increased pressure can compromise blood flow and nerve function. When assessing a client with a long-leg cast who reports severe pain, the nurse should be vigilant for signs and symptoms of compartment syndrome.

Option a is a correct answer because pallor (paleness) in the exposed portion of the left foot may indicate compromised blood flow due to increased pressure within the compartment.

Option b is a correct answer because the inability to move the left foot suggests impaired nerve function,

which can be a sign of compartment syndrome.

Option c is not a correct answer. Increased warmth is not typically associated with compartment syndrome; instead, it may suggest inflammation or infection.

Option d is not a correct answer. Ecchymosis (bruising) is not typically associated with compartment syndrome, as it is more commonly observed in cases of injury or trauma.

Option e is a correct answer because paresthesia (abnormal sensations like tingling or numbness) in the left foot can indicate nerve compression and is a potential symptom of compartment syndrome.

By identifying the presence of pallor, inability to move the foot, and paresthesia, the nurse can recognize indications of compartment syndrome and take appropriate actions to address the condition promptly.

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 The nurse must inject the corresponding amount of air for the dose needed, ensuring that the insulin can be withdrawn smoothly and accurately without bubbles, which could affect the dose.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