A nurse is collecting data on a client who has mitral valve stenosis. Which of the following findings should the nurse expect?
Heart murmur
Bradycardia
Clubbing of the fingers
Barrel chest
The Correct Answer is A
Choice A reason: A heart murmur is a common finding in clients who have mitral valve stenosis. It is a sound produced by turbulent blood flow through the narrowed valve. The murmur is usually heard as a low-pitched rumbling sound during diastole.
Choice B reason: Bradycardia is not a typical finding in clients who have mitral valve stenosis. Bradycardia is a slow heart rate, usually below 60 beats per minute. Mitral valve stenosis can cause tachycardia, which is a fast heart rate, due to increased cardiac workload and reduced cardiac output.
Choice C reason: Clubbing of the fingers is not a sign of mitral valve stenosis. Clubbing is a deformity of the fingertips and nails that occurs due to chronic hypoxia. Mitral valve stenosis can cause pulmonary hypertension and pulmonary edema, which can impair gas exchange, but not to the extent of causing clubbing.
Choice D reason: Barrel chest is not a sign of mitral valve stenosis. Barrel chest is a condition where the chest is enlarged and rounded due to chronic lung disease. Mitral valve stenosis can affect the lungs by increasing the pressure in the pulmonary circulation, but it does not cause structural changes in the chest wall.

Correct Answer is C
Explanation
Choice A reason: The nurse applies the sterile drape prior to cleansing the perineal area. This is a correct action by the nurse, as it helps to prevent contamination of the catheter insertion site and maintain a sterile field.
Choice B reason: The nurse coats the indwelling urinary catheter with lubricant. This is a correct action by the nurse, as it helps to ease the insertion of the catheter and reduce the risk of trauma or infection.
Choice C reason: The nurse separates the client's labia with her dominant hand. This is an incorrect action by the nurse, as it violates the principle of sterile technique. The nurse should use her non-dominant hand to separate the labia and expose the urethral meatus, and use her dominant hand to hold the catheter. The non-dominant hand should not touch anything else after separating the labia, as it is considered contaminated.
Choice D reason: The nurse provides perineal care prior to inserting the urinary catheter. This is a correct action by the nurse, as it helps to reduce the bacterial load and prevent infection. The nurse should use soap and water to cleanse the perineal area from front to back, and use a new washcloth for each stroke.
Correct Answer is B
Explanation
Choice A reason: Respiratory rate 28/min is not a sign of effective oxygen therapy, as it indicates tachypnea, which is a rapid breathing rate. Tachypnea can be caused by hypoxia, anxiety, fever, or pain.
Choice B reason: Pink mucous membranes are a sign of effective oxygen therapy, as they indicate adequate oxygenation of the tissues. Pink mucous membranes are a normal finding, while pale, cyanotic, or jaundiced mucous membranes can indicate hypoxia or other problems.
Choice C reason: Heart rate 110/min is not a sign of effective oxygen therapy, as it indicates tachycardia, which is a rapid heart rate. Tachycardia can be caused by hypoxia, stress, dehydration, or infection.
Choice D reason: Restlessness is not a sign of effective oxygen therapy, as it indicates agitation, anxiety, or discomfort. Restlessness can be caused by hypoxia, pain, or medication side effects.
