Answer 1

66. The correct answer is A. Folate, $1.5ng/ml$. A serum B12 concentration of $700mg/ml$ is significantly elevated and may indicate a deficiency in folate, which can be a sign of drug or alcohol abuse. Folate is essential for the production and maintenance of new cells, and a deficiency can lead to anemia and other health problems. 67. The correct answer is C. Partial thromboplastin time. Hemophilia is a bleeding disorder caused by a deficiency in clotting factors, which can be detected by an abnormal partial thromboplastin time (PTT) test. This test measures the time it takes for a clot to form in a sample of blood, and a prolonged PTT can indicate a bleeding disorder. 68. The correct answer is B. Normal sinus rhythm. The given information indicates that the P waves and QRS complexes are regular, the PR interval is within the normal range, and the heart rate is within the normal range. These findings are consistent with a normal sinus rhythm, which is the normal heart rhythm. 69. The correct answer is C. Oxygen administration. In a patient experiencing symptoms of myocardial infarction (heart attack), the first intervention should be to administer oxygen. This helps to increase the oxygen supply to the heart muscle and reduce the risk of further damage. 70. The correct answer is D. Inotropic agents. Inotropic agents are medications that increase the contractility of the heart muscle, which can improve cardiac performance. They work by increasing the responsiveness of the heart muscle to the signals that stimulate it to contract. 71. The correct answer is B. An elevated creatinine level. Acute renal failure is a condition in which the kidneys suddenly lose their ability to filter waste products from the blood. An elevated creatinine level is a confirmatory investigation for acute renal failure, as creatinine is a waste product that is normally filtered out by the kidneys.
