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

Answer and Explanation

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 ["A","B","C"]

Explanation

Choice A reason:

Regular insulin combined with dextrose can be used to lower high potassium levels, serving as an antidote for hyperkalemia. This combination helps drive potassium back into the cells, reducing serum potassium levels.

Choice B reason:

Never pushing IV KCL is critical because it can cause fatal arrhythmias. Potassium chloride must be administered as an infusion over time to safely deliver the necessary potassium without causing cardiac complications.

Choice C reason:

Infusion of KCL can cause burning, extravasation, and infiltration at the infusion site. This is because potassium chloride is an irritant to veins, so the site should be monitored closely during administration.

Choice D reason:

IV push boluses of KCL are dangerous and contraindicated due to the high risk of causing life-threatening arrhythmias. KCL should always be infused slowly to mitigate this risk.

Choice E reason:

There is no specific requirement that KCL must be given with the patient supine. This position does not affect the administration or safety of potassium chloride infusion.

A. Supplemental therapy B. Replacement therapy C. Empiric therapy

Correct Answer is C

Explanation

Choice A reason:

Supplemental therapy refers to the use of additional substances or interventions to support and enhance the primary treatment. This is not relevant to the scenario described, where antibiotics are given while awaiting culture results. Supplemental therapy does not describe the preemptive use of antibiotics based on clinical judgment without confirmed microbiological evidence.

Choice B reason:

Replacement therapy typically involves providing the body with necessary substances that it is lacking, such as insulin for diabetes or thyroid hormones for hypothyroidism. This term does not apply to the scenario of administering antibiotics while waiting for culture results. Replacement therapy is used to restore normal function when the body is deficient in certain hormones or enzymes, not for treating infections.

Choice C reason:

Empiric therapy is the correct term for the administration of antibiotics based on clinical signs and symptoms before the exact cause of the infection is confirmed by culture results. This approach is used to promptly manage infections

and prevent their spread while waiting for detailed diagnostic information. It is a common practice in medicine to
