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 A
Explanation
Choice A reason: This is the best action, because compression stockings can help improve the blood flow and prevent the formation of new clots in the veins of the legs. Compression stockings can also reduce the swelling, pain, and inflammation caused by thrombophlebitis.
Choice B reason: This is an incorrect action, because cold compresses can cause vasoconstriction and worsen the blood flow and the clotting process in the affected vein. Cold compresses can also increase the discomfort and numbness of the extremity.
Choice C reason: This is an incorrect and dangerous action, because gently massaging the area can dislodge the clot and cause it to travel to the lungs, heart, or brain, resulting in a life-threatening complication, such as pulmonary embolism, myocardial infarction, or stroke.
Choice D reason: This is an incorrect and misleading statement, because heparin is not prescribed to dissolve the thrombus, but to prevent the growth and extension of the existing clot and the formation of new clots. Heparin is an anticoagulant that inhibits the clotting factors in the blood, but does not break down the clot. The body's own enzymes, such as plasmin, are responsible for dissolving the clot.
Correct Answer is D
Explanation
Choice A reason: This is a dangerous action, because recapping the needle on the syringe can increase the risk of needlestick injuries and bloodborne infections.
Choice B reason: This is an unnecessary action, because the client may be able to self-administer insulin injections with proper education and supervision.
Choice C reason: This is an inappropriate action, because the syringe should not be disposed of in the bathroom trash can, which is not a safe or sanitary place for sharps waste.
Choice D reason: This is the correct action, because placing the syringe in a puncture-proof disposal container can prevent accidental injuries and infections, and comply with the local regulations for sharps disposal.
