Question 1 of 5
The nurse recognizes which of the following factors as possibly contributing to a sentinel event?
Correct Answer: A
Rationale: 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 is caring for a client hospitalized with bipolar disorder, manic phase who is taking Eskalith (lithium carbonate). Which of the following snacks would be best for the client?
Correct Answer: C
Rationale: Lithium carbonate can cause sodium depletion, and high-sodium snacks like potato chips should be avoided to prevent toxicity. Diet cola lacks nutritional value and may contain caffeine, which can exacerbate mania. An apple is a healthy, low-sodium snack that supports hydration and nutrition. A milkshake may be high in sugar or fat, which is less ideal.
