Correct Answer: A

Rationale: The correct action is to administer IV fluids when a client's blood pressure drops significantly. This helps increase blood volume and improve circulation, stabilizing the blood pressure. Administering pain medication (B) does not address the root cause of low blood pressure. Applying a heating pad (C) is not effective in treating low blood pressure. Monitoring the client's respiratory rate (D) is important but not the immediate action needed to address a significant drop in blood pressure.

Correct Answer: A

Rationale: The correct answer is A: Monitor aPTT levels. This is crucial in intravenous heparin therapy to ensure the therapeutic range is maintained for anticoagulation without causing bleeding. Monitoring aPTT helps adjust heparin dosage to prevent clot formation or excessive bleeding. B: Monitoring for bleeding is important but not the most important action compared to monitoring aPTT levels for appropriate dosing. C: Checking platelet count is important for some anticoagulants like heparin, but aPTT monitoring is more directly related to heparin's anticoagulant effect. D: Administering a heparin antidote (protamine sulfate) is necessary in case of heparin overdose or in emergency situations but is not the primary action in routine care.

Correct Answer: A

Rationale: The correct answer is A: Assess vital signs. This is the first intervention because it provides immediate information on the client's condition and helps determine the severity of the pain. Monitoring vital signs can reveal signs of shock, dehydration, or other serious complications. Performing a CT scan (B) is not the first priority as it requires time and resources. Monitoring urine output (C) may be important but not as immediate as assessing vital signs. Monitoring for signs of shock (D) can be included in assessing vital signs but is not the primary intervention.

Correct Answer: A

Rationale: Step 1: Stop the transfusion - Febrile reaction can indicate a transfusion reaction, so stopping the transfusion is crucial. Step 2: Administer antipyretics - To reduce fever and prevent further complications. Step 3: Assess for other signs of transfusion reaction - Such as chills, rash, or hypotension. Summary: Option A is correct as it addresses the immediate need to stop the transfusion and manage the fever. Options B, C, and D do not prioritize stopping the transfusion, which is crucial in this scenario.

Correct Answer: A

Rationale: The correct answer is A: Administer antiepileptic drugs. This is the most important nursing action for a client with a history of seizures because antiepileptic drugs help prevent or reduce the frequency and severity of seizures. By ensuring the client receives their prescribed medication, the nurse can help manage the condition effectively. Placing the client on their side (B) is important to prevent aspiration if a seizure occurs, but administering antiepileptic drugs is more crucial for long-term management. Checking the airway (C) is important during and after a seizure but does not address the underlying cause. Monitoring for hypoglycemia (D) is important as a potential trigger for seizures, but administering antiepileptic drugs takes precedence in managing the condition.
