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?
Tachycardia
Cracks in oral mucous membranes
Excessive pulmonary secretions
Poor skin turgor
The Correct Answer is B
Choice A rationale:
Tachycardia, or a rapid heart rate, is not typically an adverse effect of oxygen therapy. Oxygen therapy is often used to help people with conditions like COPD, COVID-19, emphysema, and sleep apnea get enough oxygen to function and stay well. While tachycardia can be a symptom of these conditions, it is not directly caused by the oxygen therapy itself.
Choice B rationale:
Cracks in the oral mucous membranes can indeed be an adverse effect of oxygen therapy. Oxygen therapy involves the delivery of highly concentrated oxygen, which can cause irritation and dryness in the airways, including the oral mucous membranes. This can lead to cracks and discomfort in the mouth. Therefore, it’s important for healthcare providers to monitor patients receiving oxygen therapy for signs of this adverse effect.
Excessive pulmonary secretions are not typically a direct adverse effect of oxygen therapy. While conditions that often require oxygen therapy, such as pneumonia and COPD, can lead to increased pulmonary secretions, these are symptoms of the underlying disease rather than the oxygen therapy itself.
Choice D rationale:
Poor skin turgor is not typically an adverse effect of oxygen therapy. Skin turgor refers to the elasticity of the skin, and poor skin turgor is often a sign of dehydration. While oxygen therapy can cause dryness of the mucous membranes, it does not typically affect the hydration status of the skin.

Correct Answer is B
Explanation
Choice A rationale:
Administering insulin is a crucial step in managing diabetic ketoacidosis (DKA), as insulin deficiency is a primary cause of DKA12. However, it is not the first action to take when a patient presents with both DKA and hypoxia. While insulin helps to reduce blood glucose levels and suppress the production of ketones, it does not address the immediate life-threatening condition of hypoxia.
Choice B rationale:
Hypoxia, or low levels of oxygen in the body, is a medical emergency that requires immediate attention. Supplemental oxygen can help increase the oxygen levels in the patient’s blood, thereby alleviating hypoxia. In the context of a patient with DKA and hypoxia, providing supplemental oxygen would be the first action to take to stabilize the patient’s condition before addressing the DKA12.
Choice C rationale:
Checking the patient’s glucose level is an important part of managing DKA, as hyperglycemia is a key feature of this condition. However, it is not the first action to take in this scenario. While monitoring glucose levels can guide the administration of insulin and other treatments for DKA, it does not address the immediate threat posed by hypoxia.
Choice D rationale:
Administering intravenous fluids is another important step in managing DKA12. Dehydration is a common complication of DKA due to excessive urination caused by high blood sugar levels. However, similar to Choices A and C, while it is an important part of treatment, it is not the first action to take when a patient presents with both DKA and hypoxia.
Correct Answer is ["A","D","E"]
Explanation
Choice A rationale:
Antinuclear antibody (ANA) titer is a blood test that detects the presence of antinuclear antibodies, which are autoantibodies that target the body's own tissues. These antibodies are often present in people with autoimmune diseases, including rheumatoid arthritis.
While a positive ANA test does not definitively diagnose rheumatoid arthritis, it can support a diagnosis when considered alongside other clinical findings and laboratory tests.
Choice B rationale:
Blood urea nitrogen (BUN) is a blood test that measures the amount of urea nitrogen in the blood. Urea nitrogen is a waste product that is produced when the body breaks down proteins.
BUN levels can be elevated in people with kidney disease, dehydration, or certain other medical conditions. However, BUN is not specifically used to diagnose rheumatoid arthritis.
Choice C rationale:
Urinalysis is a test that examines the urine for various substances, including cells, bacteria, and chemicals.
It can be used to diagnose a variety of conditions, including urinary tract infections, kidney disease, and diabetes. However, urinalysis is not typically used to diagnose rheumatoid arthritis.
Choice D rationale:
Erythrocyte sedimentation rate (ESR) is a blood test that measures how quickly red blood cells settle at the bottom of a test tube.
A high ESR can indicate inflammation in the body.
ESR is often elevated in people with rheumatoid arthritis, as it is a marker of inflammation.
Choice E rationale:
White blood cell count (WBC) is a blood test that measures the number of white blood cells in the blood. White blood cells are part of the immune system and help fight infection.
A high WBC count can indicate an infection or inflammation.
WBC count can be elevated in people with rheumatoid arthritis, as it is a marker of inflammation.
