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
Choice A reason: A respiratory rate of 24/min is slightly higher than the normal range (12-20 breaths per minute) and does not necessarily indicate the effectiveness of furosemide in treating pulmonary edema.
Choice B reason: Adventitious breath sounds, such as crackles or wheezes, are often present in pulmonary edema and would not indicate that the furosemide is effective. The resolution of these sounds would be a better indicator of improvement.
Choice C reason: Weight loss of 1.8 kg (4 lb) in the past 24 hours likely indicates a reduction in fluid retention, which is a desired effect of furosemide in the treatment of pulmonary edema. This diuretic effect reduces the fluid overload, thereby improving the symptoms of pulmonary edema.
Choice D reason: An elevation in blood pressure is not an expected outcome of effective furosemide therapy for pulmonary edema. Furosemide is a diuretic and would more likely lead to a reduction in blood pressure due to fluid loss.
Correct Answer is D
Explanation
Choice A reason: Applying antibiotic ointment to the lesions is not recommended for the treatment of genital herpes, which is caused by a virus, not bacteria. Antiviral medications are the appropriate treatment for managing herpes outbreaks.
Choice B reason: Natural skin condoms are not effective in preventing the transmission of genital herpes because the virus can pass through the natural membrane. The use of latex or polyurethane condoms is recommended as they are more effective in reducing the risk of transmission.
Choice C reason: Expecting lesions to resolve in 6 weeks may not be accurate as the duration of a herpes outbreak can vary. Most herpes lesions tend to resolve within 2 to 4 weeks. However, the virus remains in the body and can cause recurrent outbreaks.
Choice D reason: The duration of medication for genital herpes depends on whether the treatment is for an initial outbreak, chronic suppression, or episodic therapy. For an initial outbreak, antiviral medication is typically taken for 7 to 10 days. For chronic suppression, medication might be taken daily for an extended period to prevent or reduce the frequency of outbreaks.
