Mr. D receives a daily injection of 70/30 NPH/regular insulin premix at 7:00 AM. The nurse expects that a hypoglycemic reaction is most likely to occur between:

09:00 AM and 11:00 AM

08:00 AM and 10:00 AM

07:00 AM and 09:00 AM

12:00 PM and 3:00 PM

Answer and Explanation

The Correct Answer is A

The peak time of 70/30 NPH/regular insulin premix is usually 2 to 12 hours after injection, with an average peak time of 4 to 6 hours. This means that the highest risk of hypoglycemia is typically 4 to 6 hours after the injection, which would fall between 11:00 AM and 1:00 PM. However, it's important to note that hypoglycemic reactions can occur at any time, so the client should be monitored closely throughout the day for any signs or symptoms of low blood sugar.

Correct Answer is A

Explanation

The plan of care for a patient with hypothermia and ﬂuid volume excess would typically include measures to increase the patient's body temperature and decrease their ﬂuid volume. Therefore, option a (ﬂuid restriction) would be appropriate for this patient.

Options b (administration of hypotonic IV ﬂuids) and d (administration of ion-exchange resin) would not be appropriate because they would increase the patient's ﬂuid volume rather than decrease it.

Option c (placement of an indwelling urinary catheter) may be appropriate to closely monitor the patient's urine output, which is an important indicator of their ﬂuid status. However, this alone would not be sufficient to manage the patient's hypothermia and ﬂuid volume excess.

A. 5.0 mEq/L B. 2.9 mEq/L C. 3.8 mEq/L D. 6.0 mEq/L

Correct Answer is B

Explanation

Furosemide is a loop diuretic that works by blocking the reabsorption of sodium and chloride in the ascending loop of Henle in the kidney, leading to increased urine output. However, this medication can also cause potassium loss through increased urinary excretion, which can lead to hypokalemia (low potassium level). Hypokalemia can cause confusion, weakness, and other neurological symptoms.

The normal range for serum potassium is 3.5 to 5.0 mEq/L. A potassium level of 2.9 mEq/L is below the normal range and is considered hypokalemic. Therefore, the nurse should correlate the client's confusion with the low potassium level and notify the healthcare provider to adjust the medication or provide potassium supplements if indicated.
