Question 1 of 5
The nurse is teaching the client newly started on propranolol for acute situational anxiety disorder. In addition to treating the client's anxiety, the nurse should inform the client that propranolol's use is effective in treating which associated problem?

Question 2 of 5
The nurse completes teaching insulin administration to the parent of the toddler newly diagnosed with type 1 DM. The nurse concludes that the teaching was successful when the parent makes which statement?
Correct Answer: C
Rationale: A: NPH (Humulin N) insulin can be given in the morning, but there is better glucose control if given at night. NPH peaks in 4 to 14 hours, so there is no need to make sure food is given immediately after administration. B: Insulin injections should always be rotated to prevent subcutaneous tissue damage from giving the injections in the same location. C: Lispro (Humalog) is rapid-acting insulin that peaks in 30 to 90 minutes and may last as long as 5 hours in the blood. This statement is correct, indicating teaching is effective. D: Detemir (Levemir) is long-acting and lispro (Humalog) is rapid-acting insulin. An insulin pen uses prefilled, multiple-use insulin cartridges; adding other types of insulins should not be attempted.
