Correct Answer: B

Rationale: Option B, 'I will take my bronchodilators after meals,' indicates a need for further teaching. Bronchodilators should be taken before meals to help open the airways and make breathing easier before eating. This statement suggests a misunderstanding of the timing for optimal bronchodilator effectiveness. Options A, C, and D are all appropriate strategies for facilitating eating for a client with chronic obstructive pulmonary disease.

Correct Answer: D

Rationale: When a client with a chest tube connected to wall suction complains of chest burning, it may indicate that the tube is irritating or compressing nearby tissues. Repositioning the client can help relieve this irritation by ensuring the tube is not kinked or pulling on the tissues. Increasing suction, stripping the tube, or clamping it are not appropriate actions and could potentially worsen the situation or cause harm.

Correct Answer: B

Rationale: In a client with a high respiratory rate, low PaO2, and low SaO2, the priority intervention is to improve oxygenation. Administering oxygen via a face mask will help increase the oxygen supply to the client's lungs and tissues, addressing the hypoxemia. While mechanical ventilation may be necessary in severe cases, administering oxygen is the initial and most appropriate intervention to address the client's respiratory distress. Sedatives should not be given without ensuring adequate oxygenation. Assessing for pulmonary embolism is important but not the priority at this moment when the client is experiencing respiratory distress and hypoxemia.

Correct Answer: C

Rationale: In the scenario of a pulmonary embolism, the priority medication to administer is Heparin. Heparin is an anticoagulant that helps prevent the formation of new blood clots and the growth of existing ones, which is crucial in managing pulmonary embolism. Furosemide is a diuretic used to treat fluid retention, Dexamethasone is a corticosteroid used for inflammation, and Atropine is an anticholinergic medication used for various purposes such as treating bradycardia.

Correct Answer: A

Rationale: Before initiating percussion, vibration, and postural drainage, the nurse should first auscultate the lung fields to assess the baseline lung sounds and identify areas of congestion or abnormality. This initial assessment helps the nurse to tailor the percussion and drainage techniques effectively. Assessing pulse and respirations, sputum characteristics, and providing instructions to the client for exhalation are important steps in the procedure but should follow the initial auscultation to ensure a comprehensive and individualized care approach.
