A nurse is assisting with the admission of a client who has tuberculosis with a productive cough.
Which type of isolation precautions should the nurse initiate for the client?

Airborne.

Protective.

Droplet.

Contact.

Answer and Explanation

The Correct Answer is A

Choice A rationale:

Airborne precautions should be initiated for clients with tuberculosis (TB) who have a productive cough. TB is transmitted through the airborne route when an infected individual coughs, sneezes, or talks, releasing infectious droplets into the air. Airborne precautions include the use of negative-pressure isolation rooms and N95 respirators for healthcare workers to prevent the spread of TB.

Choice B rationale:

Protective precautions are not typically used for clients with TB. Protective precautions are more commonly employed for clients with compromised immune systems to protect them from infection.

Choice C rationale:

Droplet precautions are not sufficient for clients with TB because TB is primarily transmitted via airborne particles, not droplets. Droplet precautions are used for diseases like influenza or meningitis, which are transmitted through larger respiratory droplets.

Choice D rationale:

Contact precautions are not appropriate for clients with TB because TB is primarily transmitted through the airborne route. Contact precautions are typically used for diseases that are transmitted through direct contact with the client or contaminated surfaces.

Correct Answer is B

Explanation

Choice A rationale:

Hydrogen peroxide. Hydrogen peroxide is not the recommended solution for disinfecting surfaces following a blood spill. While it can be used to clean wounds and may have some disinfectant properties, it is not as effective as bleach in destroying bloodborne pathogens.

Choice B rationale:

Bleach. Bleach is the appropriate choice for disinfecting surfaces contaminated with blood. A 10% bleach solution (1 part bleach to 9 parts water) is effective at killing bloodborne pathogens such as HIV and hepatitis B and C viruses. It should be used in healthcare settings to ensure proper disinfection after a blood spill.

Choice C rationale:

Isopropyl alcohol. Isopropyl alcohol is an effective disinfectant for some purposes, but it may not be as effective as bleach against bloodborne pathogens. It is commonly used for cleaning and disinfecting skin before medical procedures but is not the recommended choice for disinfecting surfaces following a blood spill.

Choice D rationale:

Chlorhexidine. Chlorhexidine is an antiseptic solution often used for skin disinfection before surgical procedures or invasive medical interventions. It is not typically used for disinfecting surfaces contaminated with blood.

A. Penicillin allergy. B. Egg allergy. C. Tendonitis. D. Osteoarthritis.

Correct Answer is A

Explanation

Choice A rationale:

Reporting a penicillin allergy in the client's history is essential when the client is prescribed cefaclor. Cefaclor is a cephalosporin antibiotic, and individuals with a documented penicillin allergy may have an increased risk of cross-reactivity and allergic reactions to cephalosporin antibiotics. Therefore, it is crucial to report a penicillin allergy to the provider to evaluate the potential risks and consider alternative antibiotics if necessary.

Choice B rationale:

An egg allergy is not directly relevant to the prescription of cefaclor. While allergies to various substances can be important in healthcare, egg allergy is not a contraindication or concern when prescribing cefaclor. Therefore, it does not require specific reporting in this context.

Choice C rationale:

Tendonitis is not directly related to the prescription of cefaclor. Tendonitis is an inflammatory condition affecting tendons and is not typically a contraindication for cefaclor or other cephalosporin antibiotics.
