Answer to Question 1
A
Feedback:
Propranolol is a beta-blocker and should be avoided in combination with insulin. The blocking of the sympathetic nervous system also blocks many of the signs and symptoms of hypoglycemia, hindering the patient's ability to recognize problems. If propranolol must be taken, the nurse will need to teach this patient other ways to recognize hypoglycemia. Furosemide, cefaclor, and metoclopramide do not cause drugdrug interactions with insulin.
Answer to Question 2
B
Feedback:
The histamine release associated with many of the depolarizing NMJ blockers can cause respiratory obstruction with wheezing and bronchospasm. Hyperkalemia is an adverse effect of the depolarizing NMJ blockers, ACh is what is acted on by the NMJ blockers, and serotonin is a distracter for this question.
