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
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.
Correct Answer is C
Explanation
Before administering any medication, the nurse should confirm the potassium level to ensure that it is still elevated and needs to be treated. Potassium levels can fluctuate, so repeating the test will ensure that the client receives the appropriate treatment.
Options (a) Withhold the medication and (b) Administering a hypertonic solution may be appropriate interventions depending on the client's condition, but confirming the potassium level is the first step.
Option (d) Monitoring for paresthesia is important but not the first action that the nurse should take.
