A client presents to the emergency department with muscle aches, headache, fever, and describes a recent loss of taste and smell.
The nurse obtains a nasal swab for COVID-19 testing. Which action is most important for the nurse to take?

Choice A rationale:

Carbon dioxide is primarily eliminated through the lungs, not the kidneys. While the kidneys do play a role in acid-base balance, their primary mechanism for regulating pH is through the excretion or retention of bicarbonate ions (HCO3-), not carbon dioxide itself.

The kidneys' ability to compensate for respiratory acidosis is limited. In cases of severe respiratory acidosis, the kidneys may not be able to adequately compensate, leading to a further decrease in blood pH.

Choice B rationale:

Hyperventilation would actually decrease carbon dioxide levels in the blood, not increase them. Hyperventilation is a state of rapid, deep breathing that leads to increased exhalation of carbon dioxide. This can result in respiratory alkalosis, which is the opposite of respiratory acidosis.

Choice D rationale:

Low blood oxygen levels (hypoxia) can stimulate respiration, but this would not directly cause respiratory acidosis. In fact, hypoxia can sometimes lead to respiratory alkalosis due to hyperventilation.

Respiratory acidosis is primarily caused by impaired carbon dioxide elimination, not decreased oxygen levels.

Choice C rationale:

High levels of carbon dioxide in the blood (hypercapnia) are the hallmark feature of respiratory acidosis. This can occur due to a variety of factors that impair ventilation, such as:

Chronic obstructive pulmonary disease (COPD) Asthma

Pneumonia Sleep apnea

Neuromuscular disorders that affect breathing Drug overdose (e.g., opioids)

The accumulation of carbon dioxide in the blood leads to a decrease in blood pH, which can have a range of negative effects on the body's organ systems.

Choice A rationale:

Leaving the dressing off would expose the wound to air and potential contamination, which could delay healing and increase the risk of infection.

While consulting with the healthcare provider is always an option, it's not necessary in this case as the nurse has the knowledge and skills to select an appropriate dressing.

Additionally, leaving the wound uncovered could cause pain and discomfort to the patient, as well as potentially disrupt the delicate granulation tissue that has already formed.

Choice C rationale:

Increasing the frequency of dressing changes could disrupt the healing process and irritate the wound bed.

It's generally recommended to change dressings only as often as necessary to keep the wound clean and moist. Excessive dressing changes can also be costly and time-consuming for both the patient and the healthcare provider. Choice D rationale:

Transparent dressings are not ideal for stage 3 pressure injuries with significant granulation tissue. These dressings are more suitable for wounds with minimal exudate and that are not actively healing. Transparent dressings can also adhere to the wound bed, causing pain and trauma upon removal.

Choice B rationale:

Hydrocolloidal gel dressings are a good choice for stage 3 pressure injuries with granulation tissue because they: Provide a moist wound environment, which promotes healing.

Absorb exudate, which helps to prevent maceration of the surrounding skin. Form a protective barrier over the wound, which helps to prevent infection.

Are comfortable for the patient and can be left in place for several days.
