Place the following steps for mixing NPH and regular insulin in the proper sequential order from # 1 to # 6 below. #1 - Prep the top of the shorter acting insulin with an alcohol swab #2 - Inject air that is equal to the ordered dosage of the shorter acting insulin using the same insulin syringe. #3 - Withdraw the ordered dosage of the shorter acting insulin using the same insulin syringe. #4 - Prep the top of the longer acting insulin vial with an alcohol swab. #5 - Inject air that is equal to the ordered dosage of the longer acting insulin using the insulin syringe. #6 - Withdraw the ordered dosage of the longer acting insulin using the same insulin syringe.
- A. 1,5,4,2,3,6
- B. 4,3,2,6, 1,5
- C. 4,2,5,3, 1,6
- D. 1,5,3,6,4,2
Correct Answer: A
Rationale: The correct sequence is: 1) Prep short-acting insulin vial, 2) Inject air into short-acting vial, 3) Withdraw short-acting insulin, 4) Prep long-acting insulin vial, 5) Inject air into long-acting vial, 6) Withdraw long-acting insulin to avoid contamination.
The nurse should turn the client on bed rest every 2 hours to prevent the development of pressure ulcers. In addition, the nurse should:
- A. Have the client walk at least twice a day
- B. Insert an indwelling urinary catheter
- C. Monitor serum albumin
- D. Monitor the white blood cell count
Correct Answer: C
Rationale: Monitoring serum albumin assesses nutritional status, which is critical for skin integrity and preventing pressure ulcers. Walking is contraindicated for bed rest, catheters increase infection risk, and white blood cell count is less relevant.
The nurse has administered aminophylline to a client with emphysema. The medication is effective when there is:
- A. Relief from spasms of the diaphragm.
- B. Relaxation of smooth muscles in the bronchioles.
- C. Efficient pulmonary circulation.
- D. Stimulation of the medullary respiratory center.

The nurse is teaching a client who is taking insulin about the signs of diabetic ketoacidosis, which include:
- A. Kussmaul's respirations
- B. Excessive hunger
- C. Dry, flaky skin
- D. High blood pressure
Correct Answer: A
Rationale: Kussmaul's respirations (rapid, deep breathing) are a hallmark of diabetic ketoacidosis as the body compensates for acidosis. Excessive hunger is more typical of hypoglycemia, and dry skin or hypertension are less specific.
The nurse is caring for a client who has just undergone a lumbar puncture. Which of the following interventions is most appropriate in the immediate post-procedure period?
- A. Encourage ambulation to prevent stiffness.
- B. Keep the client flat for 4-6 hours.
- C. Administer oral fluids immediately.
- D. Apply heat to the puncture site.
Correct Answer: B
Rationale: Keeping the client flat for 4-6 hours post-lumbar puncture reduces the risk of spinal headache due to cerebrospinal fluid leakage.
