Correct Answer is B

Explanation

Choice A rationale: Dopamine is not the appropriate medication for an allergic reaction. It is a neurotransmitter and is not used in the treatment of anaphylaxis.

Choice C rationale: Norepinephrine is not the medication of choice for an allergic reaction. It primarily acts as a vasoconstrictor and is used in conditions like septic shock.
Choice D rationale: Pseudoephedrine is a decongestant and is not the appropriate medication for treating an allergic reaction with respiratory distress.

Correct Answer is A

Explanation

Choice A rationale: Respiratory depression can occur and persist for hours after the removal of a fentanyl patch. It is crucial to monitor respiratory status closely and be aware of the potential delayed onset of respiratory depression.
Choice B rationale: Fentanyl, like any opioid, carries risks, and safety precautions should be observed. However, it is not completely without risks, especially in certain populations or situations.
Choice C rationale: Using a heating pad with a fentanyl patch is not recommended, as it can increase drug absorption and the risk of overdose.
Choice D rationale: Fentanyl patches have a delayed onset of action, and the patient will not experience immediate pain relief. It may take several hours for the full effect to be achieved after the application of the patch.
