Question 1 of 5.
Extract:Laboratory reference ranges Potassium3.5-5.0 mEq/L(3.5-5.0 mmol/L) INRNormal: 0.8-1.1Therapeutic: 1.5-4.0
The nurse recognizes which of the following factors as possibly contributing to a sentinel event?
A. Administered warfarin to a client with an INR of 6.0
B. Administered flumazenil to a client who overdosed on lorazepam
C. Initiated nitroprusside infusion in a client with blood pressure of 210/112 mm Hg
D. Administered insulin/dextrose to a client with potassium level of 7.2 mEq/L (7.2 mmol/L)
Explanation: Administering warfarin with an INR of 6.0 (therapeutic range 2.0-3.0) risks severe bleeding, a sentinel event. Flumazenil is appropriate for lorazepam overdose, nitroprusside for hypertensive crisis, and insulin/dextrose for hyperkalemia are correct interventions.
Question 2 of 5.
The nurse approaches a 4-year-old boy to administer a medication. The child has no identification armband. Which action is most appropriate?
A. Check the room and bed number the child is in with the room and bed number on the medication order and administer the medication if they agree
B. Ask the child what his name is before administering the medication
C. Ask the child if his name is George (the name on the medication order) and administer the medication if the child says that is his name
D. Ask the adults at the bedside what the child's name is and administer the medication if the adults verify the name of the child
Explanation: Verifying the child's identity with adults at the bedside ensures safety, as children may not reliably confirm their own identity, and room/bed numbers are not sufficient for identification.
