A nurse is caring for a patient with pneumonia who has been on oxygen therapy for several days.
Which of the following symptoms should the nurse recognize as a potential adverse effect of oxygen therapy?
Tachycardia.
Poor skin turgor.
Excessive pulmonary secretions.
Cracks in oral mucous membranes.
The Correct Answer is D
Choice A rationale
Tachycardia is not a common adverse effect of oxygen therapy. It is more likely to be associated with conditions such as fever, anemia, or hypoxia.
Choice B rationale
Poor skin turgor is a sign of dehydration, not a typical adverse effect of oxygen therapy. Oxygen therapy does not directly affect the body’s hydration status.
Choice C rationale
Excessive pulmonary secretions are not a direct adverse effect of oxygen therapy. Conditions such as pneumonia or bronchitis often cause increased secretions.
Choice D rationale
Cracks in the oral mucous membranes can occur as a result of oxygen therapy. Oxygen can dry out the mucous membranes, leading to discomfort and potential cracking.

Correct Answer is B
Explanation
Choice A rationale
Assisting the guest to the floor and beginning mouth-to-mouth resuscitation is not the appropriate initial response. The guest’s symptoms indicate choking, and the Heimlich maneuver is the recommended first aid response.
Choice B rationale
The Heimlich maneuver is the correct response when someone is choking. The guest’s symptoms of a weak cough, inability to speak, and grasping the throat are classic signs of choking.
Choice C rationale
Observing the guest before taking further action is not appropriate in this situation. Immediate action is required to clear the guest’s airway.
Choice D rationale
Slapping the guest on the back is not the recommended response for choking in adults. It can potentially cause the object to become more deeply lodged in the throat.
Correct Answer is C
Explanation
Choice A rationale
Mycoplasmal pneumonia, also known as walking pneumonia, is typically not an airborne disease. Standard precautions, including the use of a surgical mask, are usually sufficient when caring for these patients.
Choice B rationale
Scarlet fever is caused by group A Streptococcus bacteria, which are spread through respiratory droplets. Standard precautions, including the use of a surgical mask, are usually sufficient when caring for these patients.
Choice C rationale
Tuberculosis is an airborne disease. Healthcare providers should wear an N95 respirator when caring for a client with tuberculosis to protect themselves from inhaling the bacteria.
Therefore, Choice C is the correct answer.
Choice D rationale
Scabies is caused by a mite and is spread through direct skin-to-skin contact. It is not an airborne disease, so an N95 respirator is not necessary when caring for a client with scabies.
