When a client is suffering from respiratory difficulty and requires suctioning, the appropriate method to use is:

Correct Answer: B

Rationale: When a client is suffering from respiratory difficulty and requires suctioning, the appropriate method to use is a portable or wall suction machine with tubing and collection receptacle. This method is necessary to effectively remove excess secretions or fluids from the airway and improve the client's breathing. Goggles are not needed in this situation as they are not directly related to the suctioning procedure. Dextrose-and-water solution and nasal cannula are also not appropriate methods for suctioning and would not effectively address the respiratory difficulty.

Correct Answer: D

Rationale: The correct answer is D: Obstruction. Obstruction of the airway can lead to respiratory insufficiency by blocking the flow of air in and out of the lungs. This can result in inadequate oxygen exchange, leading to respiratory distress. Expiration (choice A) is the process of exhaling air, not a problem with the airway itself. Hypercapnia (choice B) is an elevated level of carbon dioxide in the blood, which can be a consequence of respiratory insufficiency but is not a direct problem with the airway. Infection (choice C) can also affect the airway, but it is not as common of a cause of respiratory insufficiency as obstruction.

Correct Answer: A

Rationale: The correct answer is A: Peripheral edema. In right-sided heart failure, the right side of the heart is unable to effectively pump blood to the lungs for oxygenation, leading to fluid backup in the venous system. This results in increased pressure in the peripheral veins, leading to fluid leakage into the surrounding tissues, causing peripheral edema. Basilar crackles (B) are associated with left-sided heart failure due to pulmonary congestion. Chest pain (C) is not typically a primary symptom of right-sided heart failure. Cyanosis (D) is usually seen in advanced stages of heart failure when oxygen saturation is severely compromised and is not specific to right-sided heart failure.

Correct Answer: A

Rationale: The correct answer is A: Monitor the client for subcutaneous emphysema. Subcutaneous emphysema is a potential complication of a chest tube insertion, characterized by air trapped under the skin. The nurse should assess the client for signs like a crackling sensation upon palpation. This action is crucial as early detection can prevent serious complications. Choices B and C are incorrect. Continuous bubbling in the water seal chamber indicates an air leak, which should be reported immediately. Keeping the drainage system above the chest level can lead to backflow of drainage into the client, increasing the risk of infection. Choice D is incorrect as clamping the chest tube during ambulation can cause a tension pneumothorax.

Correct Answer: A

Rationale: The correct answer is A because the elderly client with pneumonia getting restless may indicate a change in condition or potential complications, requiring immediate assessment. Restlessness can be a sign of decreased oxygenation or sepsis in pneumonia patients. Choice B is incorrect as a headache in a young adult with influenza is not typically an immediate priority compared to potential respiratory distress in the elderly client. Choice C is incorrect as tidaling in the chest drainage system is expected and does not necessarily require immediate assessment unless other signs of distress are present. Choice D is incorrect as green drainage from the nose in a client with a sinus infection may indicate a bacterial infection but is not typically an urgent concern compared to potential acute respiratory compromise in the elderly client with pneumonia.
