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.

Answer and Explanation

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 C

Explanation

Step 1 is to determine how many mL to administer. The client needs 300 mg of amoxicillin and the available medication is 250 mg/5 mL. So, the calculation is (300 mg ÷ 250 mg/mL) × 5 mL.
Step 2 is to perform the calculation. The result is 6 mL.

A. Raised toilet seats B. Throw rugs C. Water heater temperature 54.4°C (130° F) D. Bathtub with rails E. Electric cords behind furniture

Correct Answer is ["B","C","E"]

Explanation

Choice A rationale
Raised toilet seats are not a safety risk for older adults. In fact, they can help prevent falls in the bathroom by reducing the distance an individual has to move to sit down and stand up from the toilet.
Choice B rationale
Throw rugs are a safety risk for older adults. They can easily cause tripping and falling, especially if the edges are not secured.
Choice C rationale

A water heater temperature of 54.4°C (130° F) is a safety risk. Water at this temperature can cause burns, especially in older adults who may have decreased sensitivity to heat.
Choice D rationale
Bathtubs with rails are not a safety risk for older adults. Rails can provide support and stability when getting in and out of the bathtub, reducing the risk of falls.
Choice E rationale
Electric cords behind furniture are a safety risk. They can be a tripping hazard and can also pose a fire risk if they are damaged.
