A charge nurse has four new clients arriving on the unit for admission. Which of the following clients should the nurse place in airborne precautions?
A client who has tuberculosis.
A client who has pneumonia.
A client who has shigella.
A client who has strep throat.
The Correct Answer is A
Choice A Reason:
Tuberculosis (TB) is a highly contagious bacterial infection that primarily affects the lungs and is spread through airborne particles. When a person with active TB coughs, sneezes, or talks, they release tiny droplets containing the bacteria into the air, which can be inhaled by others1. Therefore, placing a client with TB in airborne precautions is essential to prevent the spread of the infection. This involves using a negative pressure room and requiring healthcare workers to wear N95 respirators or higher-level protection.
Choice B Reason:
Pneumonia is an infection that inflames the air sacs in one or both lungs, which can fill with fluid or pus. While pneumonia can be caused by bacteria, viruses, or fungi, it is typically spread through respiratory droplets rather than airborne particles. Therefore, droplet precautions, rather than airborne precautions, are usually sufficient for managing clients with pneumonia. This includes wearing masks and maintaining a safe distance from the infected person.
Choice C Reason:
Shigella is a bacterial infection that primarily affects the intestines and is spread through the fecal-oral route. It is not transmitted through the air, so airborne precautions are not necessary. Instead, contact precautions are recommended to prevent the spread of Shigella, which involves wearing gloves and gowns when handling the patient or their environment and practicing good hand hygiene.
Choice D Reason:
Strep throat is a bacterial infection caused by group A Streptococcus. It is spread through respiratory droplets when an infected person coughs or sneezes. Similar to pneumonia, droplet precautions are sufficient for managing clients with strep throat. This includes wearing masks and maintaining a safe distance from the infected person to prevent the spread of the bacteria.

Correct Answer is C
Explanation
Choice A Reason:
Rotating the swab over necrotic tissue is not recommended because necrotic tissue does not provide an accurate representation of the microorganisms present in the wound. Necrotic tissue is dead tissue, and culturing it can lead to misleading results, as it may not reflect the current state of infection or the microorganisms causing the infection.
Choice B Reason:
Obtaining the sample from the outer edge of the wound is also not ideal. The outer edge of the wound may be contaminated with skin flora or other external contaminants, which can lead to inaccurate culture results. The sample should be taken from clean, viable tissue within the wound bed to ensure accurate identification of the microorganisms present.
Choice C Reason:
Applying sterile gloves to remove the outer dressing is the correct action. This step is crucial to maintain aseptic technique and prevent contamination of the wound and the specimen. Sterile gloves help ensure that the nurse does not introduce any external microorganisms into the wound while handling the dressing.
Choice D Reason:
Crushing the transport medium after obtaining the specimen is a necessary step to activate the medium and preserve the specimen during transport to the laboratory. However, this step comes after the specimen has been collected and does not directly relate to the technique of obtaining the specimen.
Correct Answer is ["B","C","D"]
Explanation
Choice A Reason:
The requirement that the client speaks the same language as the nurse is not a standard criterion for informed consent. While effective communication is crucial, the presence of an interpreter can facilitate understanding if there is a language barrier. The nurse’s signature does not confirm the language spoken by the client.
Choice B Reason:
The nurse’s signature on the informed consent form confirms that the client signed the document in the nurse’s presence. This is a standard practice to ensure that the consent was given voluntarily and that the client was present at the time of signing. It helps in verifying the authenticity of the consent.
Choice C Reason:
The nurse’s signature also confirms that the client was not coerced into signing the consent form. Informed consent must be given voluntarily, without any form of pressure or coercion. This ensures that the client’s decision is made freely and with full understanding of the procedure or treatment.
Choice D Reason:
The nurse’s signature confirms that the client has the legal authority to give consent. This means that the client is of legal age and has the mental capacity to understand the information provided and make an informed decision. It is essential to ensure that the client is legally competent to consent to the treatment or procedure.
Choice E Reason:
The requirement that the client does not have a mental health condition is not a standard criterion for informed consent. Clients with mental health conditions can still provide informed consent if they have the capacity to understand the information and make a decision. The nurse’s signature does not confirm the mental health status of the client.
