16. examination of: right hip. diagnosis: primary unilateral osteoarthritis right hip. one-view right hip: a single frontal view is obtained of the right hip. no previous studies are available for comparison. right hip arthroplasty is seen. alignment appears grossly unremarkable on this single view. there are skin staples present. air is seen in the soft tissues, likely due to recent surgery. there appear to be two drains present. the tip of one overlies the soft tissues superolateral to the greater trochanter. the second one is more inferior. the tip overlies the right proximal femoral prosthesis. impression: single view of the right hip with findings consistent with recent right total hip arthroplasty.

explanation:

the correct answer is b

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
