Question 1 of 5
A nurse is reinforcing discharge teaching about sublingual nitroglycerin with a client who has angina. Which of the following statements indicates an understanding of the instructions?
Correct Answer: C
Rationale: Feeling effects within 5 minutes shows understanding of nitroglycerin's rapid action. It's not taken with food, may increase (not slow) heart rate, and is dosed every 5 minutes up to three times.
Question 2 of 5
A nurse is preparing to mix NPH insulin and regular insulin for administration. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: Injecting air into each vial equalizes pressure for accurate withdrawal; regular insulin is drawn first, then NPH. Tuberculin syringes aren't standard, NPH isn't withdrawn first, and shaking regular insulin risks bubbles.
