A nurse is teaching a client who has asthma about how to use a metered-dose inhaler with a spacer. Which of the following pieces of information should the nurse include in the teaching?
"The spacer should make a whistling sound as you inhale."
"Hold your breath for 10 seconds once you inhale."
"Clean the spacer daily with cold water."
"Wait 30 seconds between puffs."
The Correct Answer is B
Choice A reason: The statement that "the spacer should make a whistling sound as you inhale" is not accurate. A whistling sound from the spacer may indicate that the air is being inhaled too quickly and that the user needs to slow down. The purpose of the spacer is to hold the medication released from the inhaler so that it can be inhaled more easily and effectively into the lungs, not to produce a whistling sound.
Choice B reason: Holding one's breath for 10 seconds after inhaling the medication allows for better deposition of the medication in the lungs. This pause gives the medication time to settle in the airways rather than being exhaled too quickly. It is a recommended practice to maximize the effectiveness of the inhaled medication.
Choice C reason: Cleaning the spacer is important to ensure that it works correctly and is free of any residue or debris that could obstruct the medication's path. However, the instruction to "clean the spacer daily with cold water" is incomplete. After rinsing with cold water, the spacer should be left to air dry without rinsing or wiping, as this can create static that affects medication delivery.
Choice D reason: Waiting 30 seconds between puffs is recommended to allow the user to breathe normally for a short period and to prepare for the next dose of medication. This time interval helps to ensure that the second puff is not rushed and that the medication from the first puff has had time to act.

Correct Answer is C
Explanation
The correct answer is: c. Wear a surgical mask when providing care to the client.
Choice A: Perform a Mantoux skin test on the client
The Mantoux skin test is used to screen for tuberculosis, not pertussis. Pertussis, also known as whooping cough, is a bacterial infection caused by Bordetella pertussis. The Mantoux test would not be relevant or helpful in diagnosing or managing pertussis.
Choice B: Assign the client to a negative-pressure airflow room
Negative-pressure airflow rooms are typically used for airborne infections such as tuberculosis, measles, or varicella. Pertussis is primarily spread through respiratory droplets, not airborne transmission, so a negative-pressure room is not necessary.
Choice C: Wear a surgical mask when providing care to the client
Wearing a surgical mask is appropriate when caring for a client with pertussis. Pertussis is spread through respiratory droplets, and wearing a mask helps prevent the transmission of the bacteria to healthcare workers and other patients.
Choice D: Recommend that the client’s family members receive antiviral therapy
Antiviral therapy is not effective against pertussis, which is a bacterial infection. Instead, antibiotics such as azithromycin or erythromycin are used to treat pertussis and prevent its spread. Therefore, recommending antiviral therapy would not be appropriate.
Correct Answer is A
Explanation
Choice A reason: Administering oxygen at 2 L/min is appropriate for clients with emphysema who have hypoxemia. Oxygen therapy should be titrated based on the client's oxygen saturation levels to avoid suppressing the respiratory drive.
Choice B reason: The use of incentive spirometry is beneficial for clients with emphysema as it encourages deep breathing and helps prevent atelectasis. It is an appropriate intervention to include in the plan of care.
Choice C reason: Breathing exercises for clients with emphysema typically focus on prolonging the exhalation phase, not the inhalation phase, to improve airway clearance and reduce the work of breathing.
Choice D reason: Limiting fluid intake is not generally recommended for clients with emphysema unless there are specific contraindications. Adequate hydration can help thin secretions and improve mucus clearance.
