The nurse is teaching a group of patients about self-administration of insulin. What content is important to include?
If two different insulins are ordered, they need to be given in separate injections.
When mixing insulins, the cloudy (such as NPH) insulin is drawn up into the syringe first
Patients need to use the injection site that is the most accessible.
When mixing insulins, the clear (such as regular) insulin is drawn up into the syringe first.
The Correct Answer is D
A. If two different insulins are ordered, they need to be given in separate injections: Some insulins (e.g., regular with NPH) can be mixed in one syringe if they are compatible; they do not automatically require separate injections.
B. When mixing insulins, the cloudy (such as NPH) insulin is drawn up into the syringe first: Drawing cloudy first risks contaminating the clear insulin vial; the cloudy (NPH) is drawn after the clear.
C. Patients need to use the injection site that is the most accessible: Patients should rotate injection sites (abdomen, thigh, upper arm) to prevent lipodystrophy and ensure consistent absorption -not always use the most accessible site.
D. When mixing insulins, the clear (such as regular) insulin is drawn up into the syringe first: Standard safe technique is “clear before cloudy”: draw up the clear (regular) insulin first, then the cloudy (NPH), to avoid contaminating the short-acting insulin vial.

Correct Answer is A
Explanation
A. A trauma patient with massive hemorrhage: 0.9% NaCl (normal saline) is an isotonic crystalloid appropriate for rapid volume resuscitation in hemorrhagic shock.
B. A patient with a serum calcium 7.0 mg/dL: Hypocalcemia needs calcium replacement (e.g., calcium gluconate), not specifically 0.9% NaCl as the primary correction.
C. A patient with CHF and acute pulmonary edema: Patients with CHF/pulmonary edema generally require careful fluid restriction and diuresis -isotonic boluses are usually contraindicated.
D. A patient being on dialysis: Dialysis patients often have fluid balance restrictions; routine isotonic IV fluid is not automatically indicated.
Correct Answer is ["83"]
Explanation
2 liters = 2000 mL.
Infusion rate = 2000 mL ÷ 24 hr = 83.333… mL/hr
Nearest whole number = 83 mL/hr.
Correct answer: 83 mL/hr.
