A nurse is collecting data on a client who has oxygen toxicity. Which of the following findings should the nurse expect?

Choice A reason: Confirming the client's identity by checking their wristband is the first step to ensure that the right client receives the right treatment.

Choice B reason: Providing for the client's privacy by closing the curtains is the second step to respect the client's dignity and comfort.

Choice C reason: Assisting the client into the Sims' position is the third step to facilitate the insertion of the enema tubing and the flow of the solution. The Sims' position is a side-lying position with the upper leg flexed and the lower leg straight.

Choice D reason: Inserting the tip of the enema tubing into the client's rectum is the fourth and final step to administer the enema. The nurse should lubricate the tip of the tubing, gently insert it about 3 to 4 inches into the rectum, and release the clamp to allow the solution to flow. The nurse should monitor the client for any signs of discomfort or cramping and adjust the flow rate accordingly.

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.
