The nurse suspects which cause of increased bubbling in the water seal chamber of a patient's chest drainage unit?
The patient has a pleural friction rub.
The patient has an infection at the drainage site.
The patient has a bronchopleural leak.
The patient has complete lung re-expansion.
The Correct Answer is C
A. A pleural friction rub occurs when the pleural surfaces rub against each other, usually due to inflammation, but it does not directly cause increased bubbling in the water seal chamber of a chest drainage unit.
B. An infection at the drainage site could lead to localized symptoms like redness or discharge, but it does not directly cause increased bubbling in the water seal chamber.
C. A bronchopleural leak is the most likely cause of increased bubbling in the water seal chamber. This occurs when there is an air leak between the lungs and pleural space, causing continuous air to enter the chest drainage system.
D. Complete lung re-expansion would not typically cause bubbling in the water seal chamber. Once the lung is fully re-expanded, bubbling should stop.

Correct Answer is C
Explanation
A. The client exhales as the medication is released from the inhaler: This is incorrect. The client should inhale deeply while activating the inhaler. Exhaling before inhaling will reduce the effectiveness of the medication.
B. The client takes a quick inhalation while releasing the medication from the inhaler: This is incorrect. The client should inhale slowly and deeply to allow the medication to reach the lungs effectively. A quick inhalation may result in less medication being delivered to the lungs.
C. The client holds his breath for 10 seconds after inhaling the medication: This is the correct action. Holding the breath allows the medication to settle in the lungs, enhancing its therapeutic effect.
D. The client waits 10 min between inhalations: This is not necessary unless instructed by the healthcare provider. Most guidelines suggest waiting 1 to 2 minutes between inhalations of the same medication.
Correct Answer is D
Explanation
A. A BMI of 28 kg/m² is considered overweight, but it does not meet the threshold for bariatric surgery, which typically requires a BMI of 40 or more.
B. While a BMI of 32 kg/m² may be relevant when combined with significant co-morbidities (like type 2 diabetes or hypertension), the standard guideline for bariatric surgery generally requires a BMI of 40 or higher, or 35 with comorbid conditions.
C. A BMI of 30 kg/m² is classified as obese, but bariatric surgery is generally considered for those with a BMI of 40 or higher, or 35 with severe comorbidities.
D. A BMI of 40 kg/m² or more is the standard criteria for bariatric surgery, particularly when other treatments (such as diet, exercise, and medication) have failed, or when obesity-related health issues are present.
