A nurse is teaching a client who has asthma about how to use a metered-dose inhaler with a spacer. Which of the following information should the nurse include in the teaching?
"Wait 30 seconds between puffs."
"The spacer should make a whistling sound as you inhale."
"Clean the spacer daily with cold water."
"Hold your breath for 10 seconds once you inhale."
The Correct Answer is D
D. After inhaling the medication, holding the breath for about 10 seconds allows the medication to settle in the lungs and be absorbed effectively into the bloodstream. This improves the medication's effectiveness in controlling asthma symptoms.

A Waiting 30 seconds between puffs is not a standard instruction; instead, it is generally advised to wait about one minute between puffs if multiple doses are needed.
B. The whistling sound may indicate that the client is inhaling too quickly or forcefully, which can prevent the medication from reaching the lungs effectively.
C. Cleaning the spacer is also crucial, but it is typically recommended to use warm soapy water rather than cold water, and it should be left to air dry.

Correct Answer is A
Explanation
A Sputum cultures for AFB are used to detect the presence of Mycobacterium tuberculosis, the bacteria causing TB. A negative result means that the sputum samples tested do not contain viable TB bacteria that can be transmitted to others. It indicates that the client's TB treatment has been effective in reducing the bacterial load to non-infectious levels.
B. The Quantiferon-TB Gold test is a blood test used to detect TB infection based on the immune response to TB antigens. A positive result indicates TB infection but does not differentiate between latent TB infection (not infectious) and active TB disease (potentially infectious).
C. The Mantoux tuberculin skin test (TST) is another test used to detect TB infection based on a delayed- type hypersensitivity reaction to TB antigens. An induration of less than 1 mm is considered negative and suggests that the client does not have a significant immune response to TB antigens, which could mean they are not infected with TB or the infection is not significant. This finding does not provide information on the client's infectiousness.
D. This indicates improvement in the client's symptoms, as coughing up blood-tinged sputum (hemoptysis) is a common symptom of active pulmonary TB. While improvement in symptoms is an important aspect of TB treatment, it does not directly indicate whether the client is no longer infectious. Infectiousness is primarily determined by microbiological tests such as sputum cultures for AFB.
Correct Answer is A
Explanation
A This statement indicates an understanding of the right to refuse treatment at any time, even after it has been initiated. Clients have the right to change their mind about treatment options and can withdraw their consent at any stage of treatment.
B. This statement suggests a misunderstanding of informed consent. Informed consent means the client understands the risks, benefits, and alternatives to a proposed treatment or procedure. Signing a consent form because one believes there are no other options does not reflect an informed decision- making process.
C. This statement indicates a misconception about treatment options. Clients have the right to refuse a specific treatment plan or procedure and explore other options or seek a second opinion. Refusal of one treatment does not necessarily preclude the possibility of pursuing alternative treatments.
D. This statement indicates a misunderstanding of the risks associated with treatment. It's crucial for clients to understand both the potential benefits and possible adverse effects of any treatment they undergo. Radiation treatment, like any medical intervention, carries risks that should be weighed against potential benefits.
