The nurse is teaching a patient about home administration of insulin.
The patient will receive regular insulin and NPH insulin at 0700 every day. What is important to teach the patient?
Draw up the regular insulin last.
Draw up the insulins after mixing them in a vial.
Draw up the medications in separate syringes.
Draw up the NPH insulin last.
The Correct Answer is A
Choice A rationale
When a patient is administering both regular insulin and NPH insulin, it’s important to draw up the regular insulin first. This is because regular insulin is clear and NPH insulin is cloudy. If the NPH (cloudy) insulin were drawn up into the syringe first, it could contaminate the regular (clear) insulin when drawing it up second. This could affect the action of the regular insulin, which is meant to be fast-acting.
Choice B rationale
Mixing insulins in a vial before drawing them up is not recommended. This could lead to inaccurate dosing and potential contamination of one or both vials. It’s safer and more accurate to draw up each type of insulin separately into the syringe.
Choice C rationale
While it’s possible to administer insulin using separate syringes, it’s usually not necessary and can be more cumbersome for the patient. As long as the patient is careful to avoid contaminating the insulins and to draw them up in the correct order (regular before NPH), they can be administered together in the same syringe.
Choice D rationale
Drawing up the NPH insulin last is not correct. As mentioned earlier, the regular insulin should be drawn up first to avoid contaminating it with the NPH insulin.

Correct Answer is B
Explanation
Choice A rationale
Peripheral edema is not a common side effect of stopping steroids early. Peripheral edema is often associated with conditions such as heart failure, liver disease, or kidney disease.
Choice B rationale
Low blood pressure is a common side effect when a person stops taking steroids like prednisone abruptly. Prednisone is a glucocorticoid, a type of steroid that works to mimic the effects of cortisol, a hormone that the adrenal glands produce. The body uses cortisol to regulate the heart rate and blood pressure. When a person takes prednisone for longer than a few weeks, the body reduces the amount of cortisol it makes. When a person suddenly stops taking prednisone, the body cannot immediately produce enough cortisol to make up for the missing drug. This results in withdrawal symptoms, including low blood pressure.
Choice C rationale
Hyperglycemia, or high blood sugar, is not typically a withdrawal symptom of stopping steroids early. While long-term use of steroids can lead to increased blood sugar levels, stopping the medication does not typically cause hyperglycemia.
Choice D rationale
Weight loss can be a symptom of steroid withdrawal, but it is not the most immediate or common symptom that would be anticipated in a client who stopped taking their prescribed steroids early. More common symptoms include fatigue, joint pain, and low blood pressure.
Correct Answer is B
Explanation
Choice A rationale
Hyponatremia, or low sodium levels, is not typically associated with the use of milk of magnesia. Milk of magnesia works by drawing water into the intestines, which can help to soften the stool and stimulate bowel movements. While it can affect fluid balance, it does not directly affect sodium levels in the body.
Choice B rationale
This choice is correct. Milk of magnesia contains magnesium and can lead to hypermagnesemia, or high magnesium levels, if taken in excess or if the client has impaired kidney function. Hypermagnesemia can cause various symptoms, including nausea, vomiting, low blood pressure, and in severe cases, heart arrhythmias and cardiac arrest.
Choice C rationale
Hypokalemia, or low potassium levels, is not typically associated with the use of milk of magnesia. While milk of magnesia can affect fluid and electrolyte balance, it does not directly affect potassium levels in the body.
Choice D rationale
Hypercalcemia, or high calcium levels, is not typically associated with the use of milk of magnesia. Milk of magnesia does not contain calcium, so it would not contribute to an increase in calcium levels in the body.
