A nurse is preparing regular and NPH insulin in the same syringe for a client who has diabetes mellitus.
Which of the following actions should the nurse take?

Administer the mixture within 5 minutes of preparing it.

Inject air into the regular insulin vial before injecting air into the NPH vial.

Withdraw the NPH insulin before the regular insulin.

Shake both insulin vials for 2 minutes before withdrawing the doses.

Answer and Explanation

The Correct Answer is A

Choice A rationale

Regular insulin is a rapid-acting insulin, and NPH is an intermediate-acting insulin. When mixed in the same syringe, the regular insulin molecules can bind to the protamine in the NPH suspension. This can alter the absorption profile of the regular insulin, delaying its onset of action. Administering the mixture within 5 minutes prevents this molecular interaction and ensures the regular insulin retains its rapid-acting properties.

Choice B rationale

It is crucial to inject air into the NPH insulin vial first, followed by the regular insulin vial, and then withdraw the regular insulin dose before the NPH. This specific order prevents the NPH from contaminating the regular insulin vial with protamine, which would alter the potency and action profile of the regular insulin for future use. The regular insulin is then drawn up first.

Choice C rationale

The correct procedure is to withdraw the regular insulin before the NPH insulin. The sequence is to inject air into both vials, then draw up the clear, rapid-acting regular insulin first, followed by the cloudy, intermediate-acting NPH insulin. This sequence is essential to prevent contamination of the regular insulin vial with the NPH insulin, which could affect its rapid-acting properties.

Choice D rationale

Shaking insulin vials is generally discouraged as it can lead to the formation of air bubbles, which can result in an inaccurate dose. Instead of shaking, the NPH insulin vial should be gently rolled between the palms of the hands. This action warms the insulin and resuspends the particles uniformly without causing bubbles, ensuring an accurate and consistent dose is administered. .

Correct Answer is ["18.25"]

Explanation

Step 1: convert the height from cm to meters. 175 cm ÷ 100 = 1.75 m.

Step 2: calculate BMI using the formula $BMI = weight (kg) ÷ height (m)^2$. BMI = 55.9 kg ÷ (1.75 m × 1.75 m).

Step 3: calculate the denominator. 1.75 m × 1.75 m = 3.0625 m$^2$.

Step 4: divide the weight by the denominator. 55.9 kg ÷ 3.0625 m$^2$ = 18.25. The client's BMI is 18.3.

A. Chart a summary of the data at the change of the shift. B. Note whether the client has a living will. C. Begin charting with an evaluation of the data. D. Document the client's vital signs obtained by assistive personnel.

Correct Answer is B

Explanation

Choice A rationale: Documentation of admission data should occur as soon as possible after the information is obtained. Waiting until the end of the shift to chart a summary increases the risk of forgetting critical details and delays the communication of important findings to the rest of the healthcare team.

Choice B rationale: The Patient Self-Determination Act requires healthcare facilities to ask clients upon admission if they have advance directives, such as a living will or a durable power of attorney for healthcare. This information must be clearly documented in the medical record to ensure the client's end-of-life wishes are respected.

Choice C rationale: The nursing process begins with assessment, not evaluation. Evaluation is the final step where the nurse determines if goals were met. Charting should follow the chronological order of the nursing process: assessment, diagnosis, planning, implementation, and finally, evaluation.

Choice D rationale: Registered nurses are responsible for the initial admission assessment, which includes the first set of vital signs. While assistive personnel can take routine vitals later, the nurse should personally obtain and document the baseline admission data to ensure accuracy and clinical oversight.
