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."

Answer and Explanation

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 B

Explanation

Choice A reason: The Mantoux skin test, also known as the tuberculin skin test, measures the immune response to the tuberculin purified protein derivative injected into the skin. An induration of less than 1 mm is not considered a positive result. However, the size of the induration in the Mantoux test does not indicate whether the person is infectious or not.

Choice B reason: Negative sputum cultures for acid-fast bacillus (AFB) are a strong indication that the client is no longer infectious. Pulmonary tuberculosis is diagnosed and monitored by the presence of AFB in the sputum. When the sputum cultures are negative, it suggests that the client is not excreting the bacteria and is less likely to spread the infection to others.

Choice C reason: While no longer coughing up blood-tinged sputum is a sign of clinical improvement, it does not necessarily mean that the client is no longer infectious. The absence of blood in the sputum may indicate reduced inflammation or healing of lung tissue, but the client could still be capable of transmitting tuberculosis if AFB is present in the sputum.

Choice D reason: The Quantiferon-TB Gold test is a blood test that measures the immune response to Mycobacterium tuberculosis antigens. A positive result indicates that the person's immune system has been exposed to the bacteria, but it does not determine if the person is infectious. The term "positive (negative)" is contradictory and does not provide clear information about the client's infectious status.

A. "I take my other pills at least 30 minutes after my alendronate." B. "I take my alendronate on the same day every week with an 8-ounce glass of milk." C. "I sit up and read the morning paper after taking my alendronate." D. "I will need to have a bone density test occasionally while taking this medication."

Correct Answer is B

Explanation

Choice A reason: This statement does not indicate a need for further instruction. It is recommended to wait at least 30 minutes after taking alendronate before taking other medications to ensure proper absorption of the drug.

Choice B reason: This statement indicates a need for further instruction. Alendronate should be taken with plain water, not milk. Milk and other dairy products can interfere with the absorption of alendronate due to their calcium content.

Choice C reason: This statement does not indicate a need for further instruction. Patients are advised to remain upright for at least 30 minutes after taking alendronate to prevent esophageal irritation or ulceration.

Choice D reason: This statement does not indicate a need for further instruction. Periodic bone density tests are a standard part of monitoring the effectiveness of osteoporosis treatment.
