Match the drug Digoxin to the correct classification?

A. Encourage the child to take deep breaths: While deep breaths may help improve oxygenation, the first action should be confirming that the monitoring device is correctly placed and providing accurate readings.

B. Ensure proper placement of the sensor probe: Incorrect placement of the sensor probe (e.g., on a fingernail or a cold extremity) can lead to inaccurate oxygen saturation readings. Ensuring proper placement is the priority to verify the accuracy of the reading.

C. Place the child in the Fowler's position: Fowler's position can help with breathing, but before making this change, the nurse should first verify that the pulse oximeter is working correctly.

D. Increase the oxygen flow rate: Increasing the oxygen flow rate may be necessary if the child’s oxygen saturation remains low, but the first step is to ensure the monitoring device is accurate.

A. Squatting increases the return of venous blood flow to the heart: Squatting increases systemic vascular resistance and venous return, which helps to increase oxygenation in children with Tetralogy of Fallot, as it reduces the right-to-left shunting and increases blood flow to the lungs.

B. Squatting in common resting position when a child is tachycardic: While squatting can be used to manage symptoms, this answer is misleading as squatting specifically helps in increasing blood flow and decreasing the symptoms of cyanosis in Tetralogy of Fallot, not just during tachycardia.

C. Squatting decreases arterial blood flow away from the heart: Squatting actually increases blood flow to the heart and lungs by increasing systemic vascular resistance.

D. Squatting increases the workload of the heart: Squatting helps reduce the workload on the heart in Tetralogy of Fallot by improving oxygenation and decreasing cyanosis.
