Final answer:
Option D. The nurse should immediately administer the initial dose of the anti-infective drug as prescribed to a client with possible urosepsis. Subsequently, obtaining a urine specimen for culture and sensitivity is essential, followed by monitoring fluid intake and output, as well as teaching about drug side effects once the patient is stable.
Step-by-step explanation:
In the scenario of a client admitted with possible urosepsis, the nurse's priority intervention should be to administer the initial dose of the anti-infective drug as prescribed. Urosepsis is a serious condition that can rapidly progress, and prompt antimicrobial therapy is critical to inhibit the spread of infection and improve patient outcomes. After administration of the antibiotic, obtaining a urine specimen for a prescribed culture and sensitivity test should be the next step.
Although assessing fluid intake and output is important for overall management of urosepsis, these measures do not take precedence over initiating treatment and obtaining a sample for diagnostic testing which can guide subsequent treatment decisions.
It is noteworthy to mention that once stable, the client also needs to be educated about the side effects of the prescribed anti-infective drug and how it should be properly administered. However, this is generally not the immediate action needed in an acute admission for possible urosepsis.
