A nurse is collecting data on a patient who is experiencing oxygen toxicity.
What symptoms should the nurse anticipate?
Muscle twitching
Redness of the face
Swelling around the eyes
A metallic taste in the mouth
The Correct Answer is A
Choice A rationale:
Muscle twitching is a symptom of oxygen toxicity. Oxygen toxicity is a condition resulting from the harmful effects of breathing molecular oxygen (O2) at increased partial pressures. Severe cases can result in cell damage and death, with effects most often seen in the central nervous system, lungs, and eyes. Central nervous system symptoms can include muscle twitching.
Choice B rationale:
Redness of the face is not typically associated with oxygen toxicity. Oxygen toxicity primarily affects the central nervous system, lungs, and eyes. It does not typically cause redness of the face.
Choice C rationale:
Swelling around the eyes is not a common symptom of oxygen toxicity. The primary effects of oxygen toxicity are seen in the central nervous system, lungs, and eyes. However, this does not typically manifest as swelling around the eyes.
Choice D rationale:
A metallic taste in the mouth is not a known symptom of oxygen toxicity. Oxygen toxicity is a condition that results from the harmful effects of breathing molecular oxygen (O2) at increased partial pressures. It primarily affects the central nervous system, lungs, and eyes, but a metallic taste in the mouth is not a recognized symptom.

Correct Answer is D
Explanation
Choice A rationale:
Numbness in the fingers is not typically a symptom of respiratory acidosis. This condition is characterized by an excess of carbon dioxide (CO2) in the body, which leads to a decrease in the pH of your blood, making it too acidic. Numbness in the fingers could be a symptom of other conditions, such as peripheral neuropathy or Raynaud’s disease.
Choice B rationale:
Abdominal pain is also not a common symptom of respiratory acidosis. While abdominal discomfort can occur in a variety of conditions, it is not directly associated with the acid-base balance disturbance that characterizes respiratory acidosis.
Conditions that commonly cause abdominal pain include gastrointestinal issues like gastritis, appendicitis, or gallstones.
Choice C rationale:
Dry skin is not a symptom of respiratory acidosis. The skin’s condition can be influenced by many factors, including hydration, environmental conditions, and certain skin conditions like eczema or psoriasis. Respiratory acidosis, on the other hand, is a condition that affects the acid-base balance in the body due to alveolar hypoventilation.
Choice D rationale:
Lethargy is indeed a symptom of respiratory acidosis. This condition occurs when the lungs can’t remove enough CO2, leading to an increase in the acidity of the blood. Symptoms of respiratory acidosis vary according to how long you’ve had the condition and its severity. Initial symptoms can include anxiety, blurred vision, and shortness of breath. If left untreated or in severe cases, symptoms may include fatigue, lethargy, delirium, or confusion. Therefore, a nurse assessing a patient with respiratory acidosis should anticipate lethargy among other symptoms.
Correct Answer is A
Explanation
Choice A rationale:
Mitral valve stenosis is a condition characterized by a narrowing of the mitral valve in the heart, which can lead to a variety of symptoms. One of the most common symptoms of mitral valve stenosis is a heart murmur. This is due to the turbulent flow of blood caused by the narrowed valve. The murmur is typically heard during a physical examination when a healthcare provider listens to the heart with a stethoscope.
Choice B rationale:
Bradycardia, or a slower than normal heart rate, is not typically associated with mitral valve stenosis. While mitral valve stenosis can cause irregular heart rhythms, it does not typically cause the heart rate to slow down.
Choice C rationale:
Clubbing of the fingers is a physical symptom that involves changes in the areas under and around the nails and is typically associated with conditions that cause chronic low blood oxygen levels. While mitral valve stenosis can lead to shortness of breath and fatigue, it does not typically cause clubbing of the fingers.
Choice D rationale:
A barrel chest, characterized by an increased chest diameter, is typically associated with conditions that cause chronic overinflation of the lungs, such as chronic obstructive pulmonary disease (COPD). It is not a typical symptom of mitral valve stenosis.
In conclusion, while mitral valve stenosis can lead to a variety of symptoms, the most relevant to this question is a heart murmur. Other symptoms such as bradycardia, clubbing of the fingers, and a barrel chest are not typically associated with this condition.
