Correct Answer: B

Rationale: The correct instruction for a client with home oxygen therapy is to keep oxygen tubing away from heat sources to prevent fires and other hazards. Option A is incorrect because adjusting the oxygen flow rate without healthcare provider guidance can be dangerous. Option C is incorrect as synthetic fabrics can generate static electricity, which is a fire hazard. Option D is incorrect as oxygen should be left on as prescribed unless advised otherwise.

Correct Answer: C

Rationale: After a client experiences a seizure, the nurse should immediately turn the client on their side. This action helps maintain an open airway and prevents aspiration, as it allows any secretions or vomitus to drain from the mouth. Administering oxygen can be necessary if the client is hypoxic, but turning the client on their side takes precedence to prevent complications. While documenting the seizure activity is important for the client's medical record, ensuring the client's immediate safety by positioning them correctly is the priority. Reassuring the client should follow after ensuring their physical safety.

Correct Answer: B

Rationale: The ventrogluteal muscle is the preferred site for intramuscular injections to avoid injury. Choosing the ventrogluteal site reduces the risk of injury to major nerves and blood vessels, unlike the deltoid, rectus femoris, or dorsogluteal sites. The deltoid muscle is commonly used for vaccines but has a higher risk of injury due to its proximity to the radial nerve. The rectus femoris muscle is not recommended for intramuscular injections due to its location and the risk of injury. The dorsogluteal site is also not recommended as it poses a risk of injury to the sciatic nerve and superior gluteal artery.

Correct Answer: B

Rationale: The correct answer is B: 'Use a special mattress for the client.' Using a special mattress reduces pressure on bony prominences and helps prevent pressure injuries. Repositioning the client every 4 hours (choice A) is important but using a special mattress is more effective. Keeping the client on bedrest (choice C) can increase the risk of pressure injuries due to prolonged immobility. Encouraging the client to remain in one position (choice D) is incorrect as it can lead to pressure injuries by exerting pressure on the same areas for an extended period.

Correct Answer: A

Rationale: The correct instruction the nurse should include to improve oxygenation for a client with COPD is to 'Use pursed-lip breathing during activities.' Pursed-lip breathing helps improve oxygenation by slowing down the respiratory rate, reducing the work of breathing, and keeping the airways open. This technique also helps prevent the collapse of small airways during exhalation, allowing for more complete emptying of the lungs. Choices B, C, and D are incorrect because deep breathing exercises after meals, diaphragmatic breathing during exercise, and breathing in short, shallow breaths do not specifically target the improvement of oxygenation in individuals with COPD.
