Correct Answer: A

Rationale: The correct answer is A: "Left-sided: Pulmonary congestion; Right-sided: Systemic edema." Left-sided heart failure primarily affects the lungs, leading to pulmonary congestion, which manifests as symptoms like shortness of breath and cough. On the other hand, right-sided heart failure causes systemic congestion and edema, often presenting as swelling in the legs and abdomen due to fluid retention. Choice B is incorrect because it swaps the features of left-sided and right-sided heart failure. Choice C is incorrect as it also incorrectly switches the characteristics of the two types of heart failure. Choice D is incorrect because it inaccurately associates left-sided heart failure with pulmonary congestion and right-sided heart failure with heart failure itself, which is not a distinguishing feature.

Correct Answer: A

Rationale: The key considerations for managing a patient with COPD include airway management, ensuring adequate oxygenation, promoting smoking cessation, and incorporating pulmonary rehabilitation. While airway management is crucial for maintaining patency and preventing exacerbations, oxygen therapy helps improve oxygen levels in the blood. Smoking cessation is essential to slow down disease progression and reduce exacerbation risk. Pulmonary rehabilitation plays a vital role in enhancing exercise tolerance and overall quality of life for COPD patients. Therefore, while all options are important in managing COPD, airway management is the most critical aspect.

Correct Answer: D

Rationale: The key management strategy for diabetic ketoacidosis (DKA) involves a comprehensive approach that includes administering insulin to lower blood glucose levels, monitoring blood glucose levels to ensure they are within the target range, and administering IV fluids to correct dehydration and electrolyte imbalances. Choosing 'All of the above' as the correct answer is the most appropriate because all three interventions are essential components of DKA management. Administering insulin alone without addressing fluid status and monitoring blood glucose could lead to complications. Similarly, solely focusing on IV fluids or blood glucose monitoring without insulin administration would not effectively manage DKA.

Correct Answer: A

Rationale: The correct answer is A: Yankauer catheter. The Yankauer catheter is specifically designed for oral suctioning, making it the most appropriate choice for this task. Choice B, the Bulb syringe, is typically used for suctioning small amounts of liquid from the nose or mouth. Choice C, the Suction catheter, is more commonly used for deep suctioning in the trachea or bronchi. Choice D, Sterile gloves, are necessary for infection control but are not the primary supply used for oral suctioning.

Correct Answer: B

Rationale: The correct answer is to check the client's capillary blood glucose level every 4 hours. Clients receiving TPN are at risk for hyperglycemia, so regular monitoring of blood glucose levels is essential to detect and manage hyperglycemia promptly. Administering TPN through a peripheral IV catheter (Choice A) is incorrect as TPN should be given through a central venous catheter to prevent complications. Heating the TPN solution to room temperature (Choice C) is unnecessary and not a standard practice. Weighing the client every 3 days (Choice D) is important for monitoring fluid status but is not the priority action when caring for a client receiving TPN.
