A nurse is assessing a client who has a chest tube following a thoracotomy. Which of the following findings requires intervention by the nurse?
1 cm of water present in the water seal chamber
Tidaling with spontaneous respirations
Suction chamber pressure of -20 cm H20
Drainage collection chamber is one-third full
The Correct Answer is A
A. The water seal chamber should contain at least 2 cm of water to maintain the seal and prevent air from entering the pleural space. Only 1 cm of water is inadequate and requires intervention.
B. Tidaling, or fluctuation of water with respirations, is an expected finding and indicates that the system is functioning properly.
C. A suction chamber pressure of -20 cm H₂O is the standard setting for chest tube drainage systems and does not require intervention.
D. A drainage collection chamber that is one-third full is within normal limits and simply indicates the need to continue monitoring output.

Correct Answer is C
Explanation
A. Varicella-zoster requires airborne and contact precautions due to the highly contagious nature of chickenpox (varicella) and shingles (zoster).
B. Vancomycin-resistant enterococcus (VRE) typically requires contact precautions to prevent transmission.
C. Pertussis is spread via respiratory droplets, so droplet precautions are necessary to prevent transmission.
D. Rotavirus is transmitted via the fecal-oral route and typically requires contact precautions.
Correct Answer is D
Explanation
A. Adjusting the straps on the harness once per week is not recommended. The straps should only be adjusted by a healthcare provider to ensure proper fit and alignment, as incorrect adjustments can compromise the effectiveness of the treatment.
B. Using ultra-thin diapers applied over the straps is incorrect. Diapers should be placed under the harness to prevent soiling and maintain the harness's effectiveness. Placing diapers over the straps can interfere with proper positioning.
C. Maintaining the child in a prone position while the harness is in place is not necessary. The Pavlik harness is designed to keep the hips in a flexed and abducted position, and the infant can remain in various positions that are comfortable and safe.
D. Gently massaging the skin under the straps once per day is correct. This helps prevent skin irritation and promotes circulation. Guardians should also check for redness or irritation and ensure the harness fits properly to avoid pressure injuries.
