A nurse is assessing a patient who has mitral valve stenosis.
What symptoms should the nurse expect?
Heart murmur
Bradycardia
Clubbing of the fingers
Barrel chest
Barrel chest
The Correct Answer is A
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.

Correct Answer is C
Explanation
Choice A rationale:
Hypertension is not typically a sign of hypokalemia. Hypokalemia, or low potassium levels, can cause symptoms like fatigue, muscle weakness, digestive problems, and frequent urination. Hypertension, or high blood pressure, is not commonly associated with hypokalemia.
Choice B rationale:
Cerebral edema, or swelling in the brain, is not a common symptom of hypokalemia. Hypokalemia is more likely to cause symptoms related to muscle function and digestion, as potassium is an essential mineral that helps regulate muscle contractions, maintain healthy nerve function, and regulate fluid balance.
Choice C rationale:
Muscle weakness is a common symptom of hypokalemia. Potassium helps regulate muscle contractions. When blood potassium levels are low, your muscles produce weaker contractions. This can result in symptoms like muscle weakness and fatigue.
Choice D rationale:
Hyperactive bowel sounds are not typically associated with hypokalemia. Hypokalemia can cause digestive problems, but these are more likely to be issues like constipation rather than increased bowel sounds.
Correct Answer is ["A","C"]
Explanation
The correct answers are Choices A and C.
Choice A rationale: Ignoring the urge to defecate can lead to constipation because the longer stool remains in the colon, the more water is absorbed from it, making it harder and more difficult to pass. This can lead to a cycle of further constipation and discomfort.
Choice B rationale: Increased fiber in the diet usually helps prevent constipation by adding bulk to the stool and making it easier to pass. Therefore, it is not a cause of constipation, but rather a preventive measure.
Choice C rationale: Excessive laxative use can lead to dependence on laxatives for bowel movements and can disrupt normal bowel function. Over time, this can lead to constipation as the bowel becomes less responsive to normal stimuli.
Choice D rationale: Increased activity generally helps to prevent constipation by stimulating bowel motility. Physical exercise can enhance the efficiency of the digestive system, so it is not a cause of constipation.
