While the kidneys should compensate for alkalemia, this is a slow process and would not normalize the blood pH within an hour further, adequate compensation by the kidneys would actually be a reassuring sign, eliminating choice (A). Despite the fact that this pH is normal at the moment, this patient is crashing and may start demonstrating acidemia in the near future. By extension, carbon dioxide is trapped in the blood, and the pH begins to drop. In this case, the patient begins to decrease his or her breathing rate and is not receiving adequate oxygen. When a patient with an asthma attack does not respond to treatment and has been hyperventilating for over an hour, he or she may become fatigued and may not be able to maintain hyperventilation. The score for this section of the test is combined with the other three sections to give an overall score ranging from 472 to 528. ![]() There is no specific number of right or wrong questions that corresponds to a given scaled score instead, each test administration is curved according to its level of difficulty and the performance of the test-takers on that day. The biology/biochem section of the MCAT is scored on a curved scale of 118-132, with the median score of all test takers set at 125. You can find more details on what you need to know about the overall structure of the MCAT here. These will also be designed to test both your science knowledge and application of that knowledge based on these four skills. You will also be presented with 15 discrete questions that are not associated with passages. ![]() The questions will address the four skills listed, although not every passage will require you to use each skill. ![]() The MCAT will present you with 10 passages on biology and biochemistry topics, and ask 4-7 questions about each passage.
