Correct Answer is B
Explanation
Choice A rationale: Epinephrine does increase the speed of conduction, but it does not significantly contribute to gluconeogenesis.
Choice B rationale: Epinephrine is used in cardiac arrest to increase heart rate, contractility, and conduction. In asthma, it causes bronchodilation.
Choice C rationale: While epinephrine can cause some vasodilation, it is not a primary indication for its use in cardiac arrest or status asthmaticus.
Choice D rationale: Epinephrine causes bronchodilation, not bronchoconstriction.
Correct Answer is A
Explanation
Choice A rationale: Patient-controlled analgesia (PCA) devices provide a controlled dose of medication when the patient presses the button. However, the onset of action for morphine is typically faster than 10 minutes.
Choice B rationale: PCA devices often have a lock-out period to prevent patients from administering too many doses too quickly and risking overdose.
Choice C rationale: Patient-controlled analgesia is designed for the patient to self- administer the medication. Allowing family members to press the button may lead to inaccurate dosing.
Choice D rationale: Morphine should be administered as needed, not preemptively.
Administering the medication 10 minutes before physical therapy could result in excessive sedation.
