A nurse is caring for a client who has pneumonia and has been receiving oxygen therapy for several days.
Which of the following findings should the nurse identify as an indication of an adverse effect of oxygen therapy?

Choice A rationale:

Metabolic alkalosis can occur in clients who have excessive vomiting because of the loss of hydrochloric acid. When a person vomits, they lose hydrochloric acid, and the loss of this acid can cause the blood to become more basic. This shift in pH can lead to metabolic alkalosis, a condition characterized by high levels of bicarbonate in the blood, which makes it more alkaline (or less acidic). Symptoms of metabolic alkalosis can include muscle twitching, hand tremor, nausea or vomiting, and tingling in the face, hands or feet. In severe cases, it can cause prolonged muscle contractions or seizures.

Choice B rationale:

Respiratory acidosis is a condition that occurs when the lungs can’t remove enough carbon dioxide (CO2) from the body, which causes the body’s fluids, especially the blood, to become too acidic. This can occur due to conditions that affect the lungs such as chronic obstructive pulmonary disease (COPD), asthma, or sleep apnea. However, in the case of a patient experiencing nausea and vomiting, respiratory acidosis is less likely to be the primary concern.

Choice C rationale:

Metabolic acidosis occurs when the body produces too much acid, or when the kidneys aren’t removing enough acid from the body. This can be caused by conditions such as kidney disease, lactic acidosis, or ketoacidosis. In the case of a patient experiencing nausea and vomiting, the primary concern would not typically be metabolic acidosis, as vomiting leads to a loss of stomach acid, which would more likely result in a state of alkalosis, not acidosis.

Choice D rationale:

Respiratory alkalosis is a condition that occurs when you breathe too fast or too deep and carbon dioxide levels drop too low. This causes the pH of the blood to rise and become too alkaline. When the blood is too alkaline, it means that it is not carrying enough carbon dioxide. This condition can be caused by fever, hyperventilation, or lack of oxygen. In the case of a patient experiencing nausea and vomiting, respiratory alkalosis is not typically the primary concern.

Choice A rationale:

The statement “I do my wheelchair exercises sitting in my chair” is correct. Wheelchair exercises are designed to be performed while seated in a wheelchair. They help to maintain muscle strength and flexibility, which is crucial for individuals with paralysis.

Choice B rationale:

The statement “I use a suppository every night to have a bowel movement” is also correct. Individuals with paralysis often have difficulty with bowel movements due to lack of muscle control. Using a suppository can stimulate the rectum and induce a bowel movement. Choice C rationale:

The statement “I need to catheterize myself twice a day” indicates a need for further teaching. Individuals with paralysis from the waist down following a spinal cord injury typically need to perform intermittent self-catheterization every 4-6 hours, not just twice a day. This helps to prevent urinary tract infections and bladder overdistension.

Choice D rationale:

The statement “I carry a water bottle with me because I drink a lot of water” is correct. Drinking plenty of water is important for overall health and can help to prevent urinary tract infections, which are common in individuals who self-catheterize.
