A nurse is caring for a client who has tuberculosis. Which of the following precautions should the nurse plan to implement when working with the client?
Protective
Droplet
Airborne
Contact
The Correct Answer is C
Choice A reason:
Protective precautions are not necessary because they (also known as reverse isolation) are used for immunocompromised clients to protect them from potential pathogens carried by healthcare workers or visitors.
Choice B reason:
Droplet precautions are not necessary because they are used for infections spread through larger respiratory droplets, like influenza or pertussis.
Choice C reason:
Airborne precautions should be implemented by the nurse. Tuberculosis (TB) is primarily transmitted through the airborne route, as the bacteria that cause TB can be suspended in the air as tiny particles (droplet nuclei) when an infected person coughs, sneezes, speaks, or sings. These particles can be inhaled by others, leading to the potential transmission of the disease.
Choice D reason:
Contact precautions are not necessary because they are used for infections that are transmitted through direct contact with the client or contaminated surfaces, such as MRSA (Methicillin-resistant Staphylococcus aureus) or C. difficile.

Correct Answer is A
Explanation
Choice A reason:
When preparing to insert an IV catheter, placing the tourniquet abovethe proposed insertion site helps facilitate venous distension and makes it easier to locate a suitable vein for the catheter insertion. This technique helps to improve visibility and access to the vein.
Choice B reason:
Placing the extremity in a dependent position (lower than the heart) can increase venous pressure and make it more difficult to insert the catheter.
Choice C reason:
Choosing the most proximal site on the extremity is not always necessary or appropriate. Veins distal to the proposed insertion site should be considered first, as they tend to be smaller and less accessible.
Choice D reason:
Applying a cool compress is not typically done before IV catheter insertion. It might cause vasoconstriction and make it more difficult to access a suitable vein.
Correct Answer is ["200"]
Explanation
To calculate the dose of gentamicin, you need to convert the client's weight from pounds to kilograms, then multiply it by the dosage.
1 lb = 0.453592 kg (approximately)
Client's weight: 220 lb Weight in kg: 220 lb × 0.453592 kg/lb = 99.79048 kg
Dosage: 2 mg/kg
Dose = Weight (kg) × Dosage (mg/kg) Dose = 99.79048 kg × 2 mg/kg = 199.58096 mg
Rounding to the nearest whole number: 200 mg
