Which of the following 3 provider prescriptions does the nurse anticipate?
Regular insulin 20 units subcutaneously
Potassium chloride 20 mEq/L intravenous PRN potassium less than 5.0 mEq/L
Initiate cardiac monitoring
0.9% sodium chloride at 15 ml/kg/hr for 1 hr and then reduce to 10 ml/kg/hr
Regular insulin continuous intravenous infusion, titrate per diabetic ketoacidosis (DKA) protocol once potassium is greater than 3.3 mEq/L
Dextrose 5% in water (DSW) intravenous at 5 ml/kg/hr for 4 hr
Blood glucose checks every 4 hr
Insert indwelling urinary catheter
Correct Answer : B,D,E
. Potassium chloride 20 mEq/L intravenous PRN potassium less than 5.0 mEq/L
The client's potassium level is slightly elevated at 5.5 mEq/L. Potassium replacement may be necessary if the level drops below 5.0 mEq/L, which is within the anticipated range for the nurse's actions.
D.0.9% sodium chloride at 15 ml/kg/hr for 1 hr and then reduce to 10 ml/kg/hr
This prescription addresses the need for fluid resuscitation to correct dehydration and electrolyte imbalances often seen in DKA. The client's initial blood pressure of 96/65 mm Hg suggests some degree of dehydration, further supporting the use of isotonic saline.
E.Regular insulin continuous infusion, titrate per diabetic ketoacidosis (DKA) protocol once potassium is greater than 3.3 mEq/L
This prescription aligns with the client's presentation of severe hyperglycemia (468 mg/dL) and acidosis (pH 7.30), indicating diabetic ketoacidosis (DKA). Insulin infusion is crucial for lowering blood glucose levels and correcting acidosis.

Correct Answer is B
Explanation
B. After a lumbar puncture, instructing the client to lie flat on their back for a period of time (often 1-2 hours) helps prevent complications such as headaches due to CSF leakage and promotes proper sealing of the puncture site.
A Monitoring blood glucose every 2 hours is not typically necessary immediately following a lumbar puncture unless the client has pre-existing diabetes or there are specific indications to monitor glucose levels
C Tingling in the extremities is not an expected or normal occurrence following a lumbar puncture. It could indicate neurological complications such as nerve irritation or damage, which would require prompt assessment and intervention.
D. The nurse should encourage adequate hydration unless contraindicated by the client's medical condition or specific post-procedure instructions.
Correct Answer is B
Explanation
B. Petechiae indicate a risk of bleeding due to low platelet levels or dysfunction. Bleeding precautions aim to minimize the risk of injury and bleeding events.
A While knowing the blood type is generally important for medical management, it is not the immediate priority based on the presence of petechiae alone.
C. Intravenous pain medications, especially those that can affect platelet function (like NSAIDs), may increase the risk of bleeding.
D. Airborne precautions are used for diseases transmitted by airborne droplets smaller than 5 microns, such as tuberculosis or measles. Petechiae are not indicative of an airborne disease transmission risk.
