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 B
Explanation
Choice A reason: The pulse oximeter might not be accurate during times of excessive movement is a correct statement, as movement can interfere with the detection of the pulse and the oxygen saturation. The parents should try to keep the infant still and calm while using the pulse oximeter.
Choice B reason: We will notify the doctor if the pulse oximeter consistently reads 100% is an incorrect statement, as it indicates a misunderstanding of the normal range of oxygen saturation. The parents should not be alarmed if the pulse oximeter reads 100%, as it means that the infant's blood is fully saturated with oxygen. The normal range of oxygen saturation for infants is 95% to 100%.
Choice C reason: The probe of the pulse oximeter can be applied to a finger or a toe is a correct statement, as these are suitable sites for measuring the oxygen saturation in infants. The parents should make sure that the probe fits snugly and securely on the infant's finger or toe.
Choice D reason: We will rotate the probe of the pulse oximeter every 24 hours is a correct statement, as it helps to prevent skin irritation, pressure ulcers, or infection from prolonged contact with the probe. The parents should also check the infant's skin regularly for any signs of redness, swelling, or pain.

Choice C reason: Parasites are not detected by the stool guaiac test. The stool guaiac test is a chemical test that reacts with hemoglobin, a protein found in red blood cells. Parasites are organisms that live in or on another host and do not contain hemoglobin.
Choice D reason: Blood is detected by the stool guaiac test. The stool guaiac test is a chemical test that reacts with hemoglobin, a protein found in red blood cells.
