A nurse is caring for a client who has a three-chamber chest tube system. Which of the following actions should the nurse take?
Ensure 2 cm (0.8 in) of water is in the water seal chamber.
Check the patency of the tubing every 2 hr.
Keep the drainage system above the level of the client's chest.
Empty the collection chamber every 8 hr.
The Correct Answer is A
A. Ensure 2 cm (0.8 in) of water is in the water seal chamber. This is correct because maintaining the correct water level in the water seal chamber is essential for proper functioning of the chest tube system, as it prevents air from entering the pleural space.
B. Check the patency of the tubing every 2 hr. This is incorrect because continuous monitoring is required, and patency should be ensured at all times, not just at set intervals. However, frequent assessments are important.
C. Keep the drainage system above the level of the client's chest. This is incorrect because the drainage system should be kept below chest level to allow gravity drainage and prevent backflow into the pleural space.
D. Empty the collection chamber every 8 hr. This is incorrect because the collection chamber should only be emptied when full, following facility protocol, to maintain an accurate record of drainage output.

Correct Answer is B
Explanation
A. Breathlessness is not a typical symptom of a sliding hiatal hernia. However, in severe cases, large hernias may cause shortness of breath due to pressure on the diaphragm.
B. Heartburn (acid reflux) is a common symptom because the hernia allows stomach acid to move up into the esophagus, causing irritation and discomfort.
C. Abdominal cramping is not a primary symptom of a sliding hiatal hernia. Cramping is more commonly associated with gastrointestinal conditions like irritable bowel syndrome (IBS) or gastroenteritis.
D. Constipation is not directly linked to a sliding hiatal hernia. Instead, symptoms usually involve gastroesophageal reflux disease (GERD)-related issues, such as heartburn and regurgitation.
Correct Answer is A
Explanation
A. A child with cystic fibrosis and difficulty clearing secretions is the priority because airway clearance is critical in cystic fibrosis. Mucus buildup can lead to respiratory distress and infection, requiring immediate intervention.
B. A child with an atrial septal defect and a heart rate of 120/min is not the priority because a heart rate of 120/min is within the expected range for a 3-year-old and does not indicate immediate distress.
C. A child with type 1 diabetes and a blood sugar of 150 mg/dL is not the priority because this blood glucose level is slightly elevated but not critical.
D. A child with diarrhea and abdominal pain requires assessment, but dehydration or electrolyte imbalance develops over time. Airway issues take priority over gastrointestinal symptoms.
