A nurse is working with a client on the medical unit being treated for a bacterial infection of the urinary tract. Exhibits The nurse is preparing to administer the first dose of an antibiotic to a patient admitted for a urinary tract infection. Which most important action should the nurse take prior to administering the antibiotic? Click on the highlighted text below that best answers the question. A. Administering a small test dose to determine whether hypersensitivity exists. B. Having epinephrine available in the event of a severe hypersensitivity reaction. C. Monitoring the client’s temperature and blood pressure. D. Obtaining a urine specimen for culture and sensitivity.

Choice A rationale: Administering a small test dose is not typically required before giving an antibiotic unless there is a known history of severe allergies. It is more important to identify the causative organism to ensure the appropriate antibiotic is used. Choice B rationale: Having epinephrine available is a safety measure for potential severe allergic reactions, but it is not the most immediate priority. Ensuring the antibiotic is appropriate for the infection is crucial. Choice C rationale: Monitoring the client's temperature and blood pressure is important, but it is not the most immediate priority before administering the antibiotic. These parameters should be monitored throughout treatment. Choice D rationale: Obtaining a urine specimen for culture and sensitivity is the most important action before administering the antibiotic. This ensures that the correct antibiotic is prescribed based on the specific bacteria causing the infection. It helps prevent the use of ineffective antibiotics and reduces the risk of antibiotic resistance.
