A nurse is gathering data on a patient who has diarrhea.
Which of the following findings is a sign of hypokalemia?

B. Confirm the patient’s identity by checking their wristband.
Explanation: Always begin by confirming the patient’s identity to ensure the correct treatment is given to the right patient. This step is critical in maintaining patient safety and is a standard part of care.

C. Provide privacy for the patient by closing the curtains.
Explanation: After confirming identity, ensuring privacy is important for the patient’s comfort and dignity. This is especially relevant for procedures like enemas, which may cause embarrassment or discomfort.

A. Assisting the patient into the Sims’ position.
Explanation: The Sims' position, where the patient lies on their left side with the right knee flexed, is the preferred position for enema administration. This position allows for easy insertion of the enema tube and ensures that gravity helps the solution flow into the rectum and colon.

D. Insert the tip of the enema tubing into the patient’s rectum.
Explanation: Once the patient is in the correct position, the nurse carefully inserts the enema tubing into the rectum, following proper technique to ensure patient safety and comfort.

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.
