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 The nurse must inject the corresponding amount of air for the dose needed, ensuring that the insulin can be withdrawn smoothly and accurately without bubbles, which could affect the dose.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 B
Explanation
b. Methylergonovine.
Explanation:
Postpartum hemorrhage is a significant complication that can occur after childbirth. Methylergonovine is a medication commonly used to manage postpartum hemorrhage. It is an ergot alkaloid that helps to contract the uterus, reducing bleeding. It is typically administered either intramuscularly or orally.
Option a, Terbutaline, is a medication used for the management of preterm labor by relaxing the uterine smooth muscles. It is not indicated for postpartum hemorrhage.
Option c, Magnesium sulfate, is a medication used for the prevention and treatment of seizures in patients with preeclampsia or eclampsia. It is not specifically indicated for postpartum hemorrhage.
Option d, Nifedipine, is a calcium channel blocker commonly used to manage hypertension. It is not indicated for postpartum hemorrhage.
It's important to note that the specific management of postpartum hemorrhage may vary depending on the underlying cause, severity of bleeding, and individual patient factors. The healthcare provider will determine the most appropriate interventions and medications for each case.

Correct Answer is C
Explanation
Answer: C
Rationale:
A) Encourage strength-training exercise: Strength-training exercises can be beneficial in building muscle mass and improving overall strength. However, for a client with leukemia experiencing chronic fatigue, this may be too strenuous and could exacerbate their fatigue rather than alleviate it. It is better to encourage light to moderate activities based on their tolerance.
B) Increase the client's fluids to 4 L per day: While adequate hydration is important, increasing fluids to 4 L per day may not be suitable for all clients and could pose risks, particularly if there are concerns about fluid balance or renal function. This recommendation should be tailored to the client's specific needs and medical condition.
C) Increase protein in the diet: Increasing protein in the diet can help improve energy levels and support the body's repair and regeneration processes. For clients with leukemia who are experiencing chronic fatigue, a high-protein diet can aid in maintaining muscle mass and overall nutritional status, helping to combat fatigue.
D) Encourage the client to have continual bed rest: Encouraging continual bed rest can lead to deconditioning and further exacerbate fatigue. It is important to balance rest with periods of gentle activity to maintain some level of physical function and avoid complications such as muscle atrophy or deep vein thrombosis.
