A nurse is caring for a client with a pre-existing cardiovascular disease and atrial fibrillation. What type of stroke is this client at increased risk to have?
hemorrhagic stroke
thrombotic stroke
embolic stroke
subarachnoid stroke
The Correct Answer is C
Choice A reason: A hemorrhagic stroke occurs due to bleeding in the brain, often from a burst blood vessel. While individuals with cardiovascular disease might have risk factors, atrial fibrillation primarily increases the risk for strokes caused by clots, not bleeding.
Choice B reason: A thrombotic stroke is caused by a clot that forms within the blood vessels of the brain. While cardiovascular disease can contribute to thrombosis, atrial fibrillation more commonly leads to embolic strokes due to clots forming in the heart and traveling to the brain.
Choice C reason: This is the correct answer. Atrial fibrillation increases the risk of embolic strokes because it can cause blood clots to form in the heart. These clots can travel to the brain and cause an embolic stroke, which is why patients with atrial fibrillation are often on anticoagulant therapy.
Choice D reason: A subarachnoid stroke involves bleeding in the space between the brain and the surrounding membrane. It is typically associated with aneurysms or head injury, rather than atrial fibrillation. This choice does not align with the client’s condition.

Correct Answer is ["3"]
Explanation
Step 1: Determine the number of capsules required for the prescribed dose.
The prescribed dose is 900 mg, and each capsule contains 300 mg.
Step 2: Divide the prescribed dose (900 mg) by the amount in each capsule (300 mg).
900 ÷ 300 = 3 capsules.
Correct Answer is B
Explanation
Choice A reason: A nasal cannula can deliver oxygen at a rate of 1-6 L/min, but it typically provides an FiO2 ranging from 24% to 44%. It is not capable of delivering the higher concentration of 40-60% FiO2 required in the question.
Choice B reason: This is the correct answer. A simple face mask can deliver an FiO2 of 40-60% at a flow rate of 5-8 L/min. This makes it suitable for patients who need a moderate increase in oxygen concentration. The mask covers the nose and mouth, ensuring adequate delivery of the prescribed oxygen levels.
Choice C reason: An aerosol mask is generally used for administering humidified oxygen or medications and can deliver various oxygen concentrations depending on the setup. However, it is not specifically designed to deliver a consistent 40-60% FiO2 at the specified flow rate.
Choice D reason: A face tent is primarily used for patients who need humidified oxygen but cannot tolerate a mask covering their face. It delivers a variable FiO2 and is not suitable for providing a consistent 40-60% FiO2 at 5-8 L/min, making it incorrect for this scenario.
