A nurse receives a report from an assistive personnel that a client’s blood pressure is 160/95 mm Hg. Which of the following actions should the nurse take first?

Choice A rationale

Administering Albuterol nebulizer 2.5 mg stat is appropriate for acute bronchospasm. Albuterol is a beta-agonist that relaxes airway smooth muscles, improving oxygenation. It is only administered when clinically indicated.

Choice B rationale

Methylprednisolone 50 mg IV is used for severe inflammation. It suppresses immune responses and reduces cytokine activity, but it does not directly address acute symptoms needing immediate intervention.

Choice C rationale

Reassessing vital signs ensures the patient’s stability before administering medications. This is vital in emergencies to evaluate therapy needs and prevent further clinical deterioration.

Choice D rationale

Notifying the provider about worsening symptoms after administration ensures timely interventions. However, preemptive measures, like reassessing stability, take priority before escalation.

Choice A rationale

Active immunity involves the production of antibodies by B lymphocytes in response to antigen exposure, creating a specific and adaptive immune response. This process provides long-lasting immunity.

Choice B rationale

Passive immunity provides temporary immunity through the transfer of pre-formed antibodies, such as via breast milk or immunoglobulin therapy. It does not induce memory B cell activation, so lifelong immunity is not achieved.

Choice C rationale

Active immunity results in long-term immunity by stimulating the immune system to develop memory cells. It does not have a short duration as it enables sustained protection against pathogens.

Choice D rationale

Passive immunity does not involve active antigen recognition by the immune system. However, the immune system is not rendered incapable of recognizing antigens, as this statement incorrectly implies a functional deficiency.
