A nurse is reinforcing discharge instructions with the parents of an infant who has been prescribed home oxygen and pulse oximetry monitoring.
Which statement by the parents suggests that further instruction is needed?

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.

Choice A rationale:

Dry skin is not typically associated with respiratory alkalosis. Respiratory alkalosis occurs when the levels of carbon dioxide and oxygen in the blood aren’t balanced. It occurs when you breathe too fast or too deep and carbon dioxide levels drop too low. This condition does not directly cause dry skin.

Choice B rationale:

Abdominal pain is not a common symptom of respiratory alkalosis. The condition is usually caused by over-breathing (called hyperventilation) that occurs when you breathe very deeply or rapidly. While it can cause discomfort, it does not typically result in abdominal pain.

Choice C rationale:

Diarrhea is not a direct symptom of respiratory alkalosis. However, the stress or anxiety that can cause hyperventilation and lead to respiratory alkalosis might also upset the digestive system and cause diarrhea. It’s important to note that while stress and anxiety can cause both conditions, they are not a direct result of the respiratory alkalosis itself.

Choice D rationale:

Flank pain is not a symptom of respiratory alkalosis. Flank pain is often associated with kidney problems, not respiratory conditions. Respiratory alkalosis is characterized by symptoms such as dizziness, bloating, feeling light-headed, numbness or muscle spasms in the hands and feet, discomfort in the chest area, confusion, dry mouth, tingling in the arms, heart palpitations, and feeling short of breath.
