The nurse recognizes that the goals of teaching about the transmission of tuberculosis have been met when the client with tuberculosis:

Covers the mouth and nose when coughing.

Reports daily to the public health department.

Demonstrates correct use of the N95 mask.

Washes dishes and personal items after use.

Answer and Explanation

The Correct Answer is A

Choice A reason: Covering the mouth and nose when coughing is a critical measure to prevent the spread of tuberculosis (TB). TB is primarily transmitted through airborne particles when an infected person coughs, sneezes, or talks. By covering the mouth and nose, the client reduces the risk of spreading the bacteria to others, which is a fundamental goal of TB transmission education.

Choice B reason: Reporting daily to the public health department is important for monitoring and managing TB treatment, but it does not directly relate to preventing the transmission of TB. This action is more about ensuring adherence to treatment protocols and monitoring the client’s health status.

Choice C reason: Demonstrating correct use of the N95 mask is also crucial in preventing the spread of TB, especially in healthcare settings or when the client is in close contact with others. The N95 mask filters out airborne particles, including TB bacteria, thereby reducing the risk of transmission. However, this measure is typically emphasized in specific situations rather than as a general practice for all clients with TB.

Choice D reason: Washing dishes and personal items after use is good hygiene practice but is not specifically related to the transmission of TB. TB is not spread through contact with dishes or personal items but through airborne particles.

Correct Answer is D

Explanation

Choice A reason:

An increase in cellular size of the bronchi and bronchioles is not the primary issue in emphysema. Emphysema primarily affects the alveoli, the tiny air sacs in the lungs, rather than the bronchi and bronchioles.

Choice B reason:

Overexpansion of the diaphragm is not a primary problem in emphysema. While the diaphragm may become flattened due to hyperinflation of the lungs, this is a secondary effect rather than the primary issue.

Choice C reason:

A decreased ability to inhale is not the main problem in emphysema. The primary issue is difficulty exhaling due to the loss of elasticity in the alveolar walls, which leads to air trapping and hyperinflation

Choice D reason:

Destruction of alveolar walls and loss of lung elasticity is the primary physiologic problem in emphysema. This destruction leads to reduced surface area for gas exchange and impaired lung function. The loss of elasticity makes it difficult for the lungs to expel air, leading to air trapping and hyperinflation.

Correct Answer is ["25"]

Explanation

The nurse should regulate the IV flow at 25 gtts/min.

Calculation and Answer

Step 1: Determine the total volume to be infused.

Volume = 100 mL

Step 2: Determine the time over which the infusion will occur.

Time = 1 hour = 60 minutes

Step 3: Determine the drip factor.

Drip factor = 15 gtts/mL

Step 4: Calculate the IV flow rate using the formula:

Flow rate (gtts/min) = (Volume (mL) × Drop factor (gtts/mL)) ÷ Time (min)

Step 5: Substitute the values into the formula.

Flow rate (gtts/min) = (100 mL × 15 gtts/mL) ÷ 60 min

Step 6: Perform the multiplication.

100 mL × 15 gtts/mL = 1500 gtts

Step 7: Perform the division.

1500 gtts ÷ 60 min = 25 gtts/min

The nurse should regulate the IV flow at 25 gtts/min.
