After receiving a dose of penicillin, a client develops dyspnea and hypotension. The nurse suspects the client is experiencing anaphylactic shock. What should the nurse do first?
Correct Answer: B
Rationale: When a client exhibits symptoms of anaphylactic shock after receiving penicillin, the priority nursing intervention is to administer epinephrine, as prescribed, to counteract the severe allergic reaction. Epinephrine helps to improve breathing and increase blood pressure. Intubation may be necessary in severe cases to maintain airway patency. Therefore, the nurse should administer epinephrine first before considering intubation. It is crucial to act swiftly to prevent further deterioration in the client's condition.
