Types and Components of Chest Tube Drainage Systems

- There are four main types of chest tube drainage systems:

  • Wet suction: a system that uses water to create suction and a water seal
  • Dry suction: a system that uses a mechanical regulator to create suction and a water seal
  • Dry-Wet suction: a system that uses a mechanical regulator to create suction and water to create a water seal
  • Mediastinal: a system that drains air or fluid from the mediastinum without suction or water seal

- The common components of chest tube drainage systems are:

  • Collection chamber: a chamber that collects the drainage from the chest tube and has a calibrated scale to measure the amount and rate of drainage
  • Water-seal chamber: a chamber that contains water (usually 2 cm) and acts as a one-way valve to prevent air or fluid from returning to the chest cavity. It also allows for monitoring of intrapleural pressure changes by observing fluctuations (tidaling) or bubbling in the water column.
  • Suction-control chamber: a chamber that regulates the amount of suction applied to the chest cavity by using either water (usually 20 cm) or a mechanical regulator. It also indicates the presence and level of suction by observing gentle bubbling in the water column or an orange bellows in the regulator.
  • Tubing: a set of tubing that connects the chest tube to the drainage system and has clamps, stopcocks, or caps to control or occlude the flow of air or fluid. The tubing should be patent, secured, and free of kinks, loops, or dependent areas.

Questions on Types and Components of Chest Tube Drainage Systems

Correct Answer is C

Explanation

Overproduction of glucagon by the pancreas is not the primary cause of elevated blood sugar levels and excessive thirst. Glucagon, a hormone produced by the pancreas, raises blood sugar levels when necessary, but it is not the main culprit in diabetes.

Correct Answer is ["B","D"]

Explanation

Lean protein is a good choice for individuals with diabetes as it can help stabilize blood sugar levels and promote satiety without contributing to significant fluctuations in glucose.

Correct Answer is B

Explanation

Using adhesive tape to treat blisters or sores on the feet is not advised. Any wounds or foot issues should be assessed and treated by a healthcare professional to prevent infection and promote proper healing.

Correct Answer is A

Explanation

"My heart has been racing throughout the day”. is also not indicative of hypoglycemia. Rapid heart rate (tachycardia) can have multiple underlying causes, and it is not a primary symptom of low blood sugar.

Correct Answer is B

Explanation

Checking the client's oxygen saturation is not directly related to insulin administration for diabetes. It may be relevant in certain medical conditions or emergencies, but it is not a priority action before giving insulin.

Correct Answer is D

Explanation

While an intravenous infusion pump can be used for insulin administration in some situations, it is not the best choice for rapidly correcting hyperglycemia. Intravenous bolus injection provides a more immediate and precise response. Infusion pumps are more commonly used for continuous insulin infusions, such as in critical care settings.

Correct Answer is E

Explanation

Monitoring blood glucose levels more frequently is essential for clients with diabetes experiencing hypoglycemic episodes. By regularly checking blood glucose levels, the client and healthcare team can identify trends and adjust insulin or medication dosages appropriately, helping to prevent future hypoglycemic episodes.

Correct Answer is D

Explanation

Instructing the patient to take deep breaths during the insertion is not appropriate because chest tube insertion is a sterile procedure, and patients are usually not conscious during the process. The insertion site is anesthetized, and deep breaths could compromise sterile technique and increase the risk of infection.

Keeping the tubing free of kinks, loops, or dependent areas is correct. Any kinks, loops, or dependent areas can obstruct the flow of fluids and air within the chest tube system, impairing its functionality.

Notifying the physician immediately about the air leak is the appropriate nursing action. Continuous bubbling in the water-seal chamber suggests an air leak, which could compromise the effectiveness of the chest tube and require immediate medical attention.

Instructing the client to take slow, deep breaths to prevent further complications is incorrect. The client's condition requires urgent medical intervention, and slow, deep breaths would not address the acute issue of increased intrathoracic pressure and compromised lung function.

The nurse should inform the patient that the drainage color may change from serosanguineous (pale, pink, or slightly bloody) to bright red during the recovery process. Initially, the drainage may be bloody, but as healing progresses, it should become clearer. However, if the drainage suddenly become

Monitoring vital signs and oxygen saturation is essential but does not address the infection directly. Vital sign monitoring is ongoing, while obtaining cultures is a specific intervention targeted at the suspected infection.

Infection does not explain the sudden decrease in drainage and pink frothy sputum. Although obtaining cultures from the chest tube site is important to assess for infection, it is not the most appropriate intervention at this moment. The priority is to address the potential tension pneumothorax.

<p>Applying an occlusive dressing with petroleum gauze over the wound site after removal is not the standard practice. Rationale: After chest tube removal, the wound site is typically left open to allow for the drainage of any residual air or fluid. Applying an occlusive dressing can trap air or flu
