Correct Answer: B

Rationale: The correct answer is B. A 17-year-old can receive the influenza vaccine via nasal spray (LAIV) even if they have a hypersensitivity to penicillin, as this is not a contraindication for the influenza immunization. Therefore, in this scenario, the 17-year-old with a hypersensitivity to penicillin is a candidate for the nasal spray vaccine.

Correct Answer: C

Rationale: The correct answer is increased urine output. Dopamine increases cardiac output and improves renal perfusion, leading to increased urine output. This response indicates that the medication is effective in treating shock by enhancing renal function and perfusion.

Correct Answer: B

Rationale: The correct answer is B. A rash can indicate an allergic reaction to ceftriaxone, which should be reported to the provider. It is crucial to instruct the client to discontinue the medication and seek medical attention if a rash develops to prevent potential serious adverse effects.

Correct Answer: C

Rationale: The nurse should instruct the client to report a sore throat because it can indicate an infection due to the immunosuppressive effects of topotecan. Monitoring for signs of infection is crucial to prevent complications during therapy.

Correct Answer: C

Rationale: The nurse should monitor the aPTT (activated partial thromboplastin time) when caring for a client receiving Heparin therapy. The aPTT reflects the intrinsic pathway of the clotting cascade and is used to monitor the effectiveness of heparin, which primarily affects this pathway by potentiating antithrombin III. Monitoring the aPTT helps ensure that the client's blood is within the therapeutic range to prevent thrombus formation.
