What is the appropriate technique for suctioning a tracheostomy tube?
Insert the suction catheter forcefully to clear all secretions from the tracheostomy tube.
Hyper-oxygenate the patient before and after, and limit each pass to 10 seconds or less.
Insert the suction catheter until it reaches the carina, then apply suction while withdrawing the catheter.
Apply suction continuously while inserting the suction catheter into the tracheostomy tube.
The Correct Answer is B
A. Forceful insertion can cause trauma to the airway mucosa.
B. Hyper-oxygenating the patient before and after suctioning helps prevent hypoxia, and limiting suctioning time to 10 seconds or less reduces mucosal damage and patient discomfort.
C. Suction should be applied only while withdrawing the catheter, not while inserting it.
D. Continuous suction during insertion increases the risk of mucosal injury; suction is applied intermittently during withdrawal only.

Correct Answer is A
Explanation
A. The Allen test assesses collateral circulation to the hand by evaluating blood flow through the ulnar artery before cannulating the radial artery for an arterial line, ensuring adequate circulation.
B. Blood pressure assessment is important but does not specifically evaluate collateral circulation at the insertion site.
C. Monitoring heart rate and rhythm is vital for overall cardiovascular status but unrelated to local circulation for arterial line placement.
D. Oxygen saturation reflects respiratory function, not the adequacy of circulation at the insertion site.
Correct Answer is C
Explanation
A. An elevated heart rate can be a sign of hypovolemia or stress response but is not the most reliable indicator of adequate fluid resuscitation.
B. Serum hemoglobin levels may remain elevated due to hemoconcentration and are not the best indicator of resuscitation effectiveness.
C. Urine output greater than 0.5 mL/kg/hr is the most reliable and practical indicator of adequate fluid resuscitation in burn clients. It reflects renal perfusion and overall circulatory status.
D. Clear breath sounds are important but do not directly reflect the effectiveness of fluid resuscitation.
