Final answer:
The correct answer is False. Standard precautions should not be used in this situation as the focus should be on addressing the patient's immediate medical needs.
Step-by-step explanation:
Standard precautions are a set of infection control practices that healthcare providers follow to prevent the spread of infections. These precautions include hand hygiene, the use of personal protective equipment such as gloves and masks, and proper handling and disposal of sharps.
In the scenario described, the patient is vomiting blood, which indicates a potential medical emergency. In this case, healthcare providers should follow emergency procedures to stabilize the patient and treat the cause of the bleeding, rather than focusing on standard precautions. This may involve calling for medical assistance, initiating emergency measures such as administering intravenous fluids or medications, and coordinating with the surgical team or other specialists.
Overall, the priority in caring for a noninfectious, postoperative patient who is vomiting blood is to address the immediate medical needs of the patient and provide appropriate treatment, rather than following standard precautions.
