Correct Answer: D

Rationale: Thrombolytic therapy increases the risk of bleeding, not infection, fluid volume deficit, or impaired skin integrity. The most significant concern with thrombolytic therapy is the potential for bleeding complications, which can lead to various injuries. Therefore, 'Risk for injury related to effects of thrombolysis' is the most appropriate nursing diagnosis in this scenario. Choices A, B, and C are incorrect as they do not directly correlate with the primary risk associated with thrombolytic therapy.

Correct Answer: C

Rationale: The correct answer is C: Heart defects. Many children with Down syndrome are born with congenital heart defects. These heart abnormalities are more prevalent in individuals with Down syndrome than in the general population. Choices A, B, and D are incorrect because while they may be congenital defects in children, they are not commonly associated with Down syndrome. Hypospadias is a urogenital condition, pyloric stenosis affects the stomach, and hip dysplasia involves the hip joint, but these are not typically seen as frequently as heart defects in children with Down syndrome.

Correct Answer: A

Rationale: A yellow triage tag should be placed on the client with partial-thickness burns covering 10% of his lower body. Yellow tags indicate delayed treatment, suitable for serious injuries that are not immediately life-threatening. Black tags are used for deceased individuals, red tags for immediate treatment of life-threatening injuries, and green tags for minor injuries.

Correct Answer: C

Rationale: The correct answer is to decrease IV fluids to the keep vein open (KVO) rate. The client is showing signs of fluid volume excess, such as drowsiness, headache, elevated CVP, crackles, bounding pulses, and increased blood pressure. Decreasing the IV fluids will help prevent further fluid overload. Reviewing the last administration of IV pain medication (Choice A) may be necessary but addressing the fluid balance issue is the priority. Administering a PRN dose of acetaminophen (Choice B) may help with the headache but does not address the underlying fluid overload. Calculating total intake and output (Choice D) is important but does not directly address the immediate issue of fluid overload and its associated symptoms.

Correct Answer: B

Rationale: The correct intervention the nurse should implement first is to determine the client's blood pressure. Assessing the blood pressure is crucial in this situation to rule out physiological causes like hypotension leading to the client's disorientation. Administering a sedative (Choice A) without understanding the underlying cause may worsen the situation. Applying soft restraints (Choice C) should not be the initial action and can be considered later if necessary. Calling for assistance (Choice D) may be needed eventually, but assessing the client's blood pressure takes precedence to address the immediate concern.
