An employee asks the occupational health nurse about measures to prevent inhalation exposure of job-related substances.
Which of the following explanations should the nurse include?
"Take breaks outside in fresh air to clear your lungs of inhaled toxins.”.
"Consistently wear a disposable paper mask when working in an environment with inhalable toxins.”.
"Keep a fan blowing in the environment to prevent the toxic substances from becoming stagnant in the air.”.
"Wear designated protective attire and devices when working with a toxic substance.”. .
The Correct Answer is D
Choice A rationale
Taking breaks outside in fresh air can help to clear the lungs of inhaled toxins to some extent. However, this measure alone is not sufficient to prevent inhalation exposure of job-related substances.
Choice B rationale
Consistently wearing a disposable paper mask can provide some protection against inhalable toxins. However, such masks may not be effective against all types of toxins and may not provide complete protection.
Choice C rationale
Keeping a fan blowing in the environment can help to disperse toxic substances and prevent them from becoming stagnant in the air. However, this measure alone may not be sufficient to prevent inhalation exposure, and in some cases, it could even spread the toxins more widely.
Choice D rationale
Wearing designated protective attire and devices when working with a toxic substance is the most effective measure to prevent inhalation exposure. This can include items such as respirators, which are designed to filter out specific toxins and protect the respiratory system.

Correct Answer is ["A","B","C","D","E"]
Explanation
Choice A rationale
Thoracentesis may be performed to remove air from the pleural space in a client with a pneumothorax.
Choice B rationale
Obtaining arterial blood gases (ABGs) can help assess the client’s respiratory status and the severity of the pneumothorax.
Choice C rationale
A computed tomography (CT) scan of the chest can provide detailed images of the lungs and can help confirm the diagnosis of a pneumothorax.
Choice D rationale
Preparation for the insertion of a chest tube may be necessary to remove air from the pleural space and allow the lung to re-expand in a client with a pneumothorax.
Choice E rationale
Obtaining intravenous access is often necessary for administering medications and fluids.
Correct Answer is D
Explanation
Choice A rationale
While it’s true that appetite and sense of smell are closely linked, the return of appetite does not necessarily mean the return of the sense of smell, especially after a total laryngectomy.
Choice B rationale
The body does not develop an ability to smell through the stoma. The sense of smell is primarily mediated by the olfactory nerve (Cranial Nerve I), which is located in the upper part of the nasal cavity.
Choice C rationale
The sense of smell does not typically return after several months following a total laryngectomy. This is because the surgery involves removal of the larynx and separation of the airway from the mouth, nose and throat.
Choice D rationale
Breathing through a stoma after a total laryngectomy does alter the sense of smell. This is because the nose and mouth are bypassed during breathing, and these are the primary routes for smell.
