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 The nurse must inject the corresponding amount of air for the dose needed, ensuring that the insulin can be withdrawn smoothly and accurately without bubbles, which could affect the dose.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 C
Explanation
c. Ketones positive.
Explanation:
Ketones in the urine can be an indication of diabetic ketoacidosis (DKA) or other metabolic disorders. It is abnormal and should be reported to the healthcare provider for further evaluation and management. Positive ketones suggest that the body is breaking down fats for energy instead of using glucose, which can be a sign of inadequate insulin levels or utilization.
Options a, b, and d are within normal ranges or do not indicate an immediate concern. A specific gravity of 1.020 is within the normal range and indicates appropriate urine concentration. Uric acid levels of 475 mg/24 hr are not mentioned as abnormal or concerning in the context provided. Nitrites negative indicates the absence of nitrites in the urine, which is a normal finding and indicates the absence of a urinary tract infection.
However, it's important to note that clinical judgment should always be exercised, and the nurse should consider the patient's overall clinical presentation and history when interpreting laboratory results and making decisions regarding reporting to the provider.
Correct Answer is B
Explanation
Answer: B. Elevated skin patches
Rationale:
A. Constipation:
Constipation is not a typical adverse effect of cefazolin. Antibiotics generally cause gastrointestinal symptoms like diarrhea rather than constipation, so this is not a primary concern with cefazolin therapy.
B. Elevated skin patches:
Elevated skin patches may indicate an allergic reaction, such as hives or a rash, which can be a serious side effect of cefazolin. Allergic reactions to antibiotics can escalate quickly and may require immediate medical attention. Monitoring for and reporting any skin changes is important to prevent potential complications.
C. Ringing in the ears:
Tinnitus (ringing in the ears) is not commonly associated with cefazolin. This symptom is more frequently associated with certain other antibiotics, such as aminoglycosides, but is not a primary concern with cefazolin use.
D. Depression:
Depression is not a known side effect of cefazolin. While mood changes may be seen with some medications, cefazolin’s primary side effects are related to hypersensitivity reactions and gastrointestinal symptoms.
