What are the main differences between a stroke caused by ischemia and one caused by hemorrhage?

Correct Answer: A

Rationale: The correct answer is A: "Blockage in a blood vessel supplying the brain." Ischemic stroke is caused by a blockage in a blood vessel supplying the brain, leading to reduced blood flow. Hemorrhagic stroke, on the other hand, is caused by bleeding in the brain due to a ruptured blood vessel. Choices B, C, and D are incorrect. Administering thrombolytics, avoiding anticoagulants, and preparing for surgery are specific management strategies that may apply to ischemic or hemorrhagic strokes but do not define the main differences between the two types of strokes.

Correct Answer: A

Rationale: The correct answer is A. Pursed-lip breathing is a nursing consideration for patients with COPD as it helps improve oxygenation and reduces air trapping. While administering bronchodilators and corticosteroids (choice B) is part of the treatment plan, it is typically done by healthcare providers. Monitoring oxygen saturation and arterial blood gases (ABGs) (choice C) is important but not a direct nursing consideration. Teaching the patient how to use an inhaler (choice D) is relevant but not specific to COPD care.

Correct Answer: D

Rationale: The correct answer is D: Tachycardia, hypotension, and decreased urine output are classic clinical manifestations of hypovolemic shock. In hypovolemic shock, the body tries to compensate for low blood volume by increasing the heart rate (tachycardia) to maintain cardiac output, leading to hypotension and decreased urine output. Prompt fluid replacement is necessary to restore intravascular volume. Choices A, B, and C are incorrect because they do not represent the typical manifestations of hypovolemic shock.

Correct Answer: B

Rationale: Verifying the patient's identity before administration is a critical step to ensure that the correct blood product is given to the right patient, thereby preventing transfusion errors. While ensuring proper documentation of the transfusion (choice A) is important for record-keeping, verifying patient identity (choice B) directly addresses the risk of administering blood to the wrong patient. Monitoring for allergic reactions or transfusion reactions (choice C) and monitoring the patient's vital signs during transfusion (choice D) are also essential considerations during blood product administration, but verifying patient identity takes precedence to prevent potentially life-threatening errors.

Correct Answer: A

Rationale: The correct nursing intervention for a patient with acute kidney injury (AKI) includes preparing the patient for dialysis if necessary. While choices B, C, and D are also important aspects of managing AKI, the critical intervention in severe cases is to prepare the patient for dialysis to support kidney function. Providing dietary modifications to reduce potassium, monitoring urine output and electrolytes, and administering fluids are essential components of the overall care plan for AKI patients, but in cases where the condition is severe or if conservative management fails, dialysis may be required to support the patient's kidney function and prevent further complications.
