A nurse is calculating the intake of a client during the past 9 hr. The client's intake includes lactated Ringer's IV at 150 mL/hr, cefazolin 2 g IV intermittent bolus in 100 mL of 0.9% sodium chloride, two units of packed RBCs of 275 mL and 250 mL; two IV bolus infusions of 250 mL of 6.0% sodium chloride, famotidine 20 mg IV intermittent bolus in 50 mL of 0.9% sodium chloride. How many mL of intake should the nurse record?

Choice A reason: This is incorrect because insulin can be given intravenously in certain situations, such as diabetic ketoacidosis, hyperglycemic hyperosmolar state, or perioperative care.

Choice B reason: This is correct because regular insulin is the only type of insulin that can be administered intravenously, as it is a short-acting insulin that has a rapid onset and peak. Other types of insulin, such as intermediate-acting or long-acting, are not suitable for intravenous use, as they have a delayed onset and peak and may cause hypoglycemia.

Choice C reason: This is incorrect because insulin aspart and insulin lispro are rapid-acting insulins that have a faster onset and peak than regular insulin. They are not recommended for intravenous use, as they may cause severe hypoglycemia. They are usually given subcutaneously before meals to control postprandial blood glucose levels.

Choice D reason: This is incorrect because not all forms of insulin can be administered intravenously, as explained above. Only regular insulin can be given intravenously, and the dose may differ from the subcutaneous dose depending on the patient's blood glucose level and insulin sensitivity.

Choice A reason: Taking the bronchodilator inhaler first will help to open up the airways and make it easier for the corticosteroid inhaler to reach the lungs and reduce inflammation. This will improve the effectiveness and safety of the inhalers.

Choice B reason: Taking the corticosteroid inhaler first may not be as effective as taking the bronchodilator inhaler first, because the airways may be constricted and prevent the corticosteroid from reaching the lungs. This may reduce the anti-inflammatory effect of the corticosteroid and increase the risk of side effects.

Choice C reason: Taking these two drugs at least 2 hours apart is not necessary and may not be practical for the patient. The bronchodilator and the corticosteroid can be taken together, as long as the bronchodilator is taken first.

Choice D reason: It does matter which inhaler the patient uses first, because the order of the inhalers can affect their efficacy and safety. The patient should always use the bronchodilator inhaler first, followed by the corticosteroid inhaler.
