Correct Answer: A

Rationale: The most important nursing action when a patient experiences a fall is to assess the patient for injuries. This is critical to identify any potential harm or underlying issues that may require immediate attention. Calling for help and notifying the healthcare provider are important steps, but assessing the patient's condition takes precedence to ensure prompt and appropriate care. Documenting the fall is also necessary but should follow the initial assessment and care provided to the patient.

Correct Answer: C

Rationale: The correct answer is C. Clients on warfarin therapy need to have their International Normalized Ratio (INR) checked regularly to monitor the medication's effectiveness and prevent complications like clotting or bleeding. Option A is incorrect because increasing leafy green vegetables can affect INR levels due to their vitamin K content. Option B is incorrect as grapefruit juice is not a significant concern with warfarin. Option D is important for medication adherence but does not specifically address the monitoring aspect required for warfarin therapy.

Correct Answer: D

Rationale: The correct answer is D because viewing the newborn's actions as uncooperative indicates a lack of bonding, which requires intervention. Choices A, B, and C all involve appropriate and caring actions by the client towards the newborn. Holding the newborn in an en face position promotes bonding, involving the father in caring for the newborn is beneficial for family involvement, and requesting rest by asking the nurse to take the newborn to the nursery is a responsible action to ensure both the client and the newborn get adequate rest.

Correct Answer: C

Rationale: To prevent aspiration in clients receiving continuous enteral feedings, the nurse should elevate the head of the bed to 45 degrees. This position helps reduce the risk of regurgitation and aspiration. Flushing the tube with water every 4 hours (Choice A) is important for maintaining tube patency but does not directly prevent aspiration. Positioning the client on the left side during feedings (Choice B) is not specifically related to preventing aspiration in this context. Checking gastric residual every 2 hours (Choice D) is important to assess feeding tolerance but does not directly prevent aspiration.

Correct Answer: C

Rationale: The correct answer is C: aPTT. Monitoring the activated partial thromboplastin time (aPTT) is crucial when a client is receiving heparin therapy. The aPTT reflects the clotting time and helps assess the effectiveness of heparin in preventing clot formation. Keeping the aPTT within the therapeutic range ensures that the medication is working optimally. Choices A, B, and D are incorrect because serum potassium, platelets, and INR are not direct indicators of heparin's effectiveness or therapeutic range.
