A patient admitted with acute renal failure asks for pain medication for a headache described as five out of ten on the pain scale. The nurse checks the MAR and sees that the only pain medication ordered is Ibuprofen. Which of the following actions should the nurse take first to ensure patient safety?

Choice A reason: Health care providers such as medical doctors (MDs) and nurse practitioners (NPs) are responsible for diagnosing and treating medical conditions. While they play a crucial role in patient care, the development of a detailed, individualized nursing plan of care typically falls under the domain of nursing professionals.

Choice B reason: Licensed practical/vocational nurses (LPNs/LVNs) provide basic patient care under the supervision of registered nurses and physicians. They assist with implementing care plans but do not usually develop comprehensive nursing plans of care themselves.

Choice C reason: Nursing supervisors oversee the nursing staff and ensure that nursing care is delivered effectively. They may be involved in developing and overseeing care plans at a higher level but are not typically responsible for creating the individualized care plans for each patient.

Choice D reason: Registered nurses (RNs) are trained and licensed to develop individualized care plans that include nursing diagnoses, interventions, and outcomes. They work closely with patients to create and implement care plans that address specific health needs and promote self-management.

Choice A reason: Checking the patient's temperature is important for assessing the severity of the pneumonia and monitoring for fever, but it is not the priority action before administering the first dose of vancomycin.

Choice B reason: Obtaining sputum cultures is the priority action because it allows for the identification of the causative organism and determination of its antibiotic susceptibility. This helps ensure that the prescribed antibiotic is appropriate for the patient's infection. Cultures should be obtained before starting antibiotic therapy to avoid interference with culture results.

Choice C reason: Checking the patient's blood pressure is important for overall patient assessment and monitoring, especially considering potential side effects of vancomycin. However, it is not the primary action needed before the first dose of the antibiotic.

Choice D reason: Drawing a blood specimen to evaluate the white blood cell count is useful for assessing the severity of the infection and the patient's immune response. However, this can be done after obtaining the sputum cultures and is not the immediate priority before administering the antibiotic.
