A nurse is reinforcing discharge teaching about improving gas exchange with a client who has emphysema. Which of the following information should the nurse include in the teaching?
Use pursed-lip breathing during periods of dyspnea.
Limit fluid intake to 1,500 ml per day.
Practice chest breathing each day.
Wear home oxygen to maintain an SpO2 of at least 94%.
The Correct Answer is A
Choice A reason: This is the correct information, because pursed-lip breathing can help improve gas exchange by creating positive pressure in the airways, preventing air trapping and alveolar collapse, and increasing the exhalation time.
Choice B reason: This is an incorrect information, because limiting fluid intake to 1,500 ml per day can cause dehydration and thickening of the respiratory secretions, which can impair gas exchange and increase the risk of infection.
Choice C reason: This is an incorrect information, because practicing chest breathing each day can worsen gas exchange by increasing the use of accessory muscles, decreasing the diaphragmatic excursion, and reducing the lung expansion.
Choice D reason: This is an incorrect information, because wearing home oxygen to maintain an SpO2 of at least 94% can be harmful for a client who has emphysema, as it can suppress the hypoxic drive and cause carbon dioxide retention, which can lead to respiratory acidosis and coma. The client who has emphysema should wear home oxygen to maintain an SpO2 of 88% to 92%, or as prescribed by the provider.

Correct Answer is C
Explanation
Choice A reason: This is an incorrect action, because instructing the client to blink several times after instillation of the medication can cause the medication to drain out of the eye and reduce its effectiveness.
Choice B reason: This is a correct action, but not the best one. Asking the client to look straight ahead during instillation of the medication can help the nurse to aim the drop accurately and avoid touching the eye with the dropper.
Choice C reason: This is the best action, because applying pressure to the bridge of the nose after instillation of the medication can prevent the medication from entering the systemic circulation and causing adverse effects, such as bradycardia, hypotension, or bronchospasm.
Choice D reason: This is an incorrect action, because placing each drop of the medication directly on to the client's cornea can cause irritation, injury, or infection to the eye. The medication should be placed in the lower conjunctival sac of the eye.
Correct Answer is B
Explanation
Choice A reason: This is a correct statement, because using a soft toothbrush or foam swab for oral care can help prevent trauma and irritation to the mucous membranes of the mouth, which are inflamed and ulcerated due to stomatitis. The client should brush the teeth gently and avoid using dental floss.
Choice B reason: This is an incorrect statement, because using an alcohol-based mouthwash can cause burning, drying, and further damage to the mucous membranes of the mouth, which are already compromised by stomatitis. The client should avoid using any mouthwash that contains alcohol, menthol, or other harsh ingredients.
Choice C reason: This is a correct statement, because using a straw when drinking liquids can help reduce the contact and friction of the fluids with the mouth sores, which can cause pain and discomfort. The client should drink plenty of fluids to prevent dehydration and maintain hydration.
Choice D reason: This is a correct statement, because rinsing the mouth frequently with a hydrogen peroxide solution can help cleanse and disinfect the mouth, and promote healing of the mouth sores. The client should dilute the hydrogen peroxide with water and rinse the mouth at least four times a day, or as prescribed by the provider.
