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?
1,350 mL
1,600 mL
2525 mL
2,100 mL
The Correct Answer is C
The correct answer is c. 2,525 mL.
Choice A reason:
1,350 mL is calculated by considering only the lactated Ringer’s IV intake. The calculation is as follows:
- Lactated Ringer’s IV at 150 mL/hr for 9 hr: 150 mL/hr × 9 hr = 1,350 mL. This option does not include the intake from cefazolin, packed RBCs, sodium chloride boluses, or famotidine.
Choice B reason:
1,600 mL is not a correct calculation based on the given intake. This value does not accurately sum up any combination of the provided intake components.
Choice C reason:
2,525 mL is the correct total intake. The detailed calculation is:
- Lactated Ringer’s IV at 150 mL/hr for 9 hr: 150 mL/hr × 9 hr = 1,350 mL.
- Cefazolin in 100 mL of 0.9% sodium chloride: 100 mL.
- Two units of packed RBCs: 275 mL + 250 mL = 525 mL.
- Two IV bolus infusions of 250 mL of 6.0% sodium chloride: 250 mL + 250 mL = 500 mL.
- Famotidine in 50 mL of 0.9% sodium chloride: 50 mL.
Adding these together: 1,350 mL + 100 mL + 525 mL + 500 mL + 50 mL = 2,525 mL.
Choice D reason:
2,100 mL is not a correct calculation based on the given intake. This value does not accurately sum up any combination of the provided intake components.

Correct Answer is B
Explanation
Choice A reason: Insulin glargine is not the type of insulin to use for diabetic ketoacidosis, as it is a long-acting insulin that has a duration of 24 hours and no peak effect. It is used to provide basal insulin coverage and prevent hyperglycemia.
Choice B reason: Regular insulin is the type of insulin to use for diabetic ketoacidosis, as it is a short-acting insulin that has an onset of 30 to 60 minutes and a peak of 2 to 4 hours. It is used to lower the blood glucose level rapidly and correct the acidosis.
Choice C reason: Insulin detemir is also not the type of insulin to use for diabetic ketoacidosis, as it is a long-acting insulin that has a duration of 12 to 24 hours and no peak effect. It is also used to provide basal insulin coverage and prevent hyperglycemia.
Choice D reason: NPH insulin is also not the type of insulin to use for diabetic ketoacidosis, as it is an intermediate-acting insulin that has an onset of 2 to 4 hours and a peak of 4 to 12 hours. It is used to provide intermediate insulin coverage and prevent hyperglycemia.
Correct Answer is B
Explanation
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.
