Correct Answer: A

Rationale: The correct nursing intervention for a patient receiving anticoagulant therapy is to monitor INR levels and check for signs of bleeding. Monitoring the INR levels helps assess the effectiveness and safety of anticoagulant therapy, while checking for bleeding is essential due to the increased risk associated with anticoagulants. Choice B is incorrect as antiplatelet therapy is not the standard treatment for patients on anticoagulant therapy. Choice C is incorrect as providing additional anticoagulation is not a direct nursing intervention in this scenario. Choice D is incorrect because administering aspirin, an antiplatelet medication, along with anticoagulants can increase the risk of bleeding and is generally avoided.

Correct Answer: B

Rationale: The correct intervention when managing a client with delirium is to identify any reversible causes. Delirium can be caused by various factors such as infections, medications, dehydration, or metabolic imbalances. Administering antipsychotic medications (Choice A) may worsen delirium and should be avoided unless necessary for specific indications. Providing a low-stimulation environment (Choice C) is beneficial as it can help reduce agitation and confusion in individuals with delirium. Increasing environmental stimulation (Choice D) is contraindicated as it can exacerbate symptoms in delirious patients. Therefore, the priority should be on identifying and addressing reversible causes to effectively manage delirium.

Correct Answer: B

Rationale: The correct answer is to instruct the client not to get out of bed. Lorazepam is a sedative that can cause drowsiness and impair coordination. By instructing the client not to get out of bed, the nurse helps prevent falls or injuries that could occur due to the medication's sedative effects. Choice A is incorrect as keeping the client awake may not be necessary and could lead to unnecessary discomfort. Choice C is incorrect as encouraging the client to drink fluids is not directly related to the administration of lorazepam. Choice D is incorrect as early ambulation is not safe immediately after administering a sedative medication.

Correct Answer: A

Rationale: The correct instruction the nurse should include is to 'Use pursed-lip breathing during physical activity.' Pursed-lip breathing is a technique that helps improve breathing efficiency in individuals with COPD by preventing airway collapse and allowing for better air exchange. Choice B is incorrect because breathing deeply and quickly can lead to hyperventilation and worsen symptoms in COPD patients. Choice C is incorrect because the incentive spirometer is a device used to encourage deep breathing and improve lung function, so it should not be avoided. Choice D is incorrect because physical activity is important for maintaining overall health and should be encouraged in a controlled and appropriate manner for individuals with COPD.

Correct Answer: A

Rationale: The Z-track method should be used to administer IM injections in obese clients to prevent medication from leaking into subcutaneous tissue. Using a longer needle (1.5 inches) ensures that the medication reaches the muscle mass adequately. Choice C is incorrect because the deltoid muscle is not ideal for IM injections in obese clients due to inadequate muscle mass. Administering the injection at a 90° angle (perpendicular to the skin) is recommended for IM injections to ensure proper delivery into the muscle.
