A nurse is caring for a client diagnosed with adult respiratory distress syndrome (ARDS) and being treated with positive end expiratory pressure (PEEP). How does PEEP benefit the client?

It decreases trapped oxygen in the alveoli.

It promotes independent breathing efforts.

It keeps the airways and small lung spaces open.

It facilitates weaning off the mechanical ventilator.

Answer and Explanation

The Correct Answer is C

Choice A rationale
PEEP does not decrease trapped oxygen in the alveoli. Instead, it helps to increase the volume of gas remaining in the lungs at the end of expiration, which can improve oxygenation.
Choice B rationale
PEEP does not directly promote independent breathing efforts. It is a mode of mechanical ventilation used to support a patient’s breathing.
Choice C rationale
PEEP keeps the airways and small lung spaces open by increasing the pressure in the lungs at the end of expiration. This can prevent alveolar collapse and improve oxygenation in patients with conditions like ARDS23.
Choice D rationale
While PEEP can be used in the process of weaning a patient off mechanical ventilation, its primary benefit is not facilitating weaning. It is used to improve oxygenation and prevent alveolar collapse.

Correct Answer is B

Explanation

Choice A rationale
While it is important to monitor oxygen use to prevent hypoxia and hypercapnia, taking breaks from oxygen use is not typically recommended for clients with COPD. These clients often require supplemental oxygen to maintain adequate oxygen saturation.
Choice B rationale
Maintaining a low flow rate of oxygen is crucial in clients with COPD. These clients are often “CO2 retainers,” and administering a high concentration of oxygen can suppress their respiratory drive, leading to further CO2 retention and respiratory distress.
Choice C rationale
While it is important to assess for signs of skin breakdown in clients receiving oxygen therapy, this is not the priority when administering nasal oxygen to a client with COPD38.
Choice D rationale
Clients should not adjust their oxygen flow rate without medical supervision. Increasing the oxygen flow rate can lead to hyperoxia, which can be harmful, especially in clients with COPD who are CO2 retainers.

A. Client uses chewing tobacco every day. B. Client is an industrial-commercial painter. C. Client is an ultrasound technician. D. Client wears magnetic healing bracelets. E. Client’s husband smokes cigarettes.

Correct Answer is ["A","B","E"]

Explanation

Choice A rationale
Using chewing tobacco every day is a significant risk factor for laryngeal cancer. Tobacco contains many carcinogens, which can damage the cells in the larynx and lead to cancer.
Choice B rationale
Being an industrial-commercial painter is associated with an increased risk of laryngeal cancer. This is likely due to exposure to certain chemicals and toxins that are used in paints and other materials.
Choice C rationale
Being an ultrasound technician is not typically associated with an increased risk of laryngeal cancer. Ultrasound technicians are not generally exposed to the types of toxins or risk factors that are associated with laryngeal cancer.
Choice D rationale
Wearing magnetic healing bracelets is not associated with an increased risk of laryngeal cancer. There is no scientific evidence to suggest that these bracelets have any effect on cancer risk.
Choice E rationale
Having a spouse who smokes cigarettes is a risk factor for laryngeal cancer. Secondhand smoke, also known as passive smoke, contains many of the same carcinogens as the smoke inhaled by smokers. Exposure to secondhand smoke can increase a person’s risk of developing laryngeal cancer.
