For which of the following clients would the use of standard precautions alone be appropriate
Chapter 1. Infection Control Show
Certain pathogens and communicable diseases are easily transmitted and require additional precautions to interrupt the spread of suspected or identified agents to health care providers, other patients, and visitors (PIDAC, 2012). Additional precautions are used in addition to routine precautions and are defined by how a microorganism is transmitted (Perry et al., 2014). Types of Additional PrecautionsThere are three categories of additional precautions: contact precautions, droplet precautions, and airborne precautions. Contact precautions are are the most common type of additional precautions. They are used in addition to routine practice for patients who are known or suspected to be infected with microorganisms that can be transferred by direct (touching) or indirect (shared equipment) contact. Types of organisms in this category are antibiotic-resistant organisms (AROs) such as methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococci (VRE), extended spectrum beta-lactamase (ESBL), Clostridium difficile (CDI), carbapenemase-producing organisms (CPO), diarrhea, and scabies. AROs are also known as multi-drug-resistant organisms (MDROs). Droplet precautions are used in addition to routine practices for patients who are known or suspected to be infected with microorganisms that are spread through the air by large droplets. Types of organisms and unconfirmed conditions in this category include mumps, influenza, vomiting of unknown cause, norovirus, and unconfirmed cough. Airborne precautions are used in addition to routine practices for patients who are known to have or are suspected of having an illness that is transmitted by small droplet nuclei that may stay suspended in the air and be inhaled by others. These particles can remain infectious for a long period of time when spread through the air. Types of organisms in this category include tuberculosis (TB), measles, chicken pox (varicella), disseminated zoster, and severe acute respiratory syndrome (SARS). Special considerations:
Tables 1.1, 1.2, and 1.3. summarize the three categories of additional precautions. Table 1.1 Contact Precaution Guidelines
Personal Protective Equipment (PPE)Additional precautions require the use of personal protective equipment (PPE), which is equipment or clothing worn by staff to prevent the transmission of infection from patient to staff or to family member (PIDAC, 2012). All PPE must be applied and removed in a specific order to ensure the skin, nose, mouth, and eyes are covered to prevent transmission of infection to health care providers. Depending on the type of additional precaution or risk assessment, a gown, goggles, face shield, and mask (surgical or N95) may be used during patient care. Refer to Checklist 6 for steps to take when donning (putting on) PPE. Checklist 6: Donning PPE
See Checklist 7 for steps on how to doff or remove PPE. Checklist 7: Doffing PPE
Video 1.1Blood or Body Fluid (BBF) ExposureA blood and body fluid (BBF) exposure is defined as an exposure to potentially infectious body fluids or blood through the following methods: a puncture wound by a sharp object or needle (percutaneous exposure), from a body fluid/blood splash onto your mucous membranes (permucosal exposure) or exposure through eczema, an open wound/skin or scratch (non-intact skin exposure) (BCCDC, 2015). Post-exposure management is only required when (1) percutaneous, permucosal, or non-intact skin is exposed to a BBF; (2) the exposure is to blood or potentially infectious body tissue or fluid; (3) the source is considered potentially infectious (e.g., patient is part of a high-risk group, exposure occurred in a high-risk setting, or patient has a positive test); and (4) the exposed person is considered susceptible to HIV, hepatitis B, or hepatitis C. Checklist 8 explains what to do if exposed. Checklist 8: BBF Exposure
For which client would the use of standard precautions alone be appropriate?Standard Precautions are intended to be applied to the care of all patients in all healthcare settings, regardless of the suspected or confirmed presence of an infectious agent.
In which situation would standard precautions be adequate?Standard precautions apply to all patients regardless of their diagnosis or presumed infection status. Standard precautions must be used in the handling of: blood (including dried blood) all other body fluids/substances (except sweat), regardless of whether they contain visible blood.
For which patients would the nurse be required to use droplet precautions?Use Droplet Precautions for patients known or suspected to be infected with pathogens transmitted by respiratory droplets that are generated by a patient who is coughing, sneezing, or talking.
Which precautions would the nurse take when caring for a client with tuberculosis TB )?You suspect tuberculosis (TB). What type of precautions would be appropriate? The correct answer is C, Airborne Isolation Precautions. A surgical type face mask should be placed on the patient and he should be moved to a negative-pressure room as soon as possible.
