A nurse is assessing a client who has a chest tube with a water seal drainage system.
Upon assessment, the nurse notes tidaling in the water seal.
Which of the following is an explanation for the tidaling?
The lung has re-expanded.
There is a loop of tubing below the drainage system.
The system is working properly.
The tubing is partially obstructed by clots.
The Correct Answer is C
The correct answer is Choice C, the system is working properly.
Choice A rationale: The lung has re-expanded is incorrect. If the lung has re-expanded, there would be no tidaling in the water seal chamber, as the pleural space would be restored to its normal negative pressure. Tidaling indicates that there is still air or fluid in the pleural space that needs to be drained
Choice B rationale: There is a loop of tubing below the drainage system is incorrect. A loop of tubing below the drainage system would not cause tidaling in the water seal chamber, but it could cause fluid accumulation in the tubing, which could impair the drainage and increase the risk of infection. The tubing should be straight and free of kinks or loops
Choice C rationale: The system is working properly is correct. Tidaling in the water seal chamber means that the water level rises and falls with the patient’s respirations. This is normal and expected, as it indicates that the chest tube is patent and connected to the pleural space, and that the drainage system is airtight and preventing air or fluid from entering the pleural space. Tidaling should stop when the lung is fully re-expanded or the chest tube is clamped
Choice D rationale: The tubing is partially obstructed by clots is incorrect. If the tubing is partially obstructed by clots, there would be no tidaling in the water seal chamber, as the chest tube would not be able to drain the air or fluid from the pleural space. The water level in the water seal chamber would be stagnant, and the patient may experience respiratory distress. The tubing should be checked regularly for clots and milked gently if needed

Correct Answer is ["A","E"]
Explanation
Choice A rationale:
Contractures are a risk for this client due to the lack of movement and constant positioning on one side. Contractures occur when the muscles, tendons, or ligaments shorten and tighten, limiting range of motion and flexibility. This can be a result of prolonged immobility or lack of use of the muscles.
Choice B rationale:
Calcium resorption is not a risk for this client. Calcium resorption refers to the process where bone tissue is broken down and calcium is released into the bloodstream. This process is not directly related to immobility or multiple sclerosis.
Choice C rationale:
Hypocalcemia, or low calcium levels in the blood, is also not a direct risk for this client. While immobility can lead to bone loss over time, it does not directly cause hypocalcemia.
Choice D rationale:
Diarrhea is not a risk for this client based on the information provided. Diarrhea can be a symptom of many conditions but there is no indication in the scenario that this client is at risk.
Choice E rationale:
Urinary stasis is a risk for this client due to their immobility. When a person is immobile, urine can pool in the bladder, creating an environment where bacteria can grow, potentially leading to urinary tract infections.
Correct Answer is D
Explanation
The correct answer is Choice D.
Choice A rationale: Requesting additional information about the caller's relationship to the client does not ensure the caller's identity is verified, and it could still result in a breach of confidentiality.
Choice B rationale: Providing a general update about the client's condition over the telephone is not appropriate, as it could breach the client's confidentiality.
Choice C rationale: Referring the family member to the client's provider for the update respects confidentiality and ensures that information is only provided to authorized individuals, maintaining the client's privacy.
Choice D rationale: Encouraging the family member to contact the client directly for information ensures that the client has control over their own information and maintains confidentiality. This action respects the client's privacy and autonomy.
