The nurse is preparing to administer 20 units of NPH insulin to a client. Before administering the medication, the nurse should implement which intervention?

Massage the chosen injection site.

Assess the client's urine for the presence of glucose.

Assess the client's understanding of diabetes.

Have a colleague confirm the dosage.

Answer and Explanation

The Correct Answer is D

This intervention is important to ensure accurate dosing and prevent medication errors. Insulin is a high-alert medication, meaning that it has a high potential for causing significant harm to the patient if administered incorrectly. Doublechecking the insulin dosage with a colleague can help prevent errors in dosing, which could lead to hypoglycemia or hyperglycemia in the client. It is also important to confirm the dosage since insulin dosing is based on individualized factors such as the client's blood glucose levels, weight, and overall health status.

Correct Answer is B

Explanation

When using an insulin pump, the best site for inserting the infusion set is in the abdomen. This is because the abdomen has a higher amount of subcutaneous fat and a larger surface area, which allows for better absorption of the insulin. In addition, the abdomen is more accessible and easier to reach for self-insertion, and it also allows for better flexibility and comfort for the patient during daily activities.

It is important to rotate the infusion set insertion sites within the abdomen to avoid tissue damage and to ensure consistent absorption. Other sites, such as the hip, thigh, or deltoid, may be used but are generally not recommended due to the potential for slower absorption, tissue damage, and discomfort for the patient

A. An increase in serum lactate B. A decrease in hemoglobin and hematocrit C. An increase in white blood cells D. A decrease in potassium accompanied by an increase in sodium

Correct Answer is A

Explanation

A. An increase in serum lactate – This is a critical laboratory value that can indicate lactic acidosis, a serious side effect associated with metformin, especially in older adults or those with renal impairment. An increase in serum lactate necessitates discontinuation of the medication.

B. A decrease in hemoglobin and hematocrit – While this change may indicate anemia, it is not directly associated with the need to discontinue metformin. Further evaluation of the cause of anemia would be necessary.

C. An increase in white blood cells – This could indicate an infection or inflammatory process but does not specifically necessitate the discontinuation of metformin.

D. A decrease in potassium accompanied by an increase in sodium – While electrolyte imbalances should be monitored, this change does not directly indicate that metformin should be discontinued.
