A 72-year-old woman comes to the physician for follow-up care. One year ago, she was diagnosed with a 3.8-cm infrarenal aortic aneurysm found incidentally on abdominal ultrasound. She has no complaints. She has hypertension, type 2 diabetes mellitus, and COPD. Current medications include hydrochlorothiazide, lisinopril, glyburide, and an albuterol inhaler. She has smoked a pack of cigarettes daily for 45 years. Her temperature is 37°C (98.6°F), pulse is 90/min, respirations are 12/min, and blood pressure is 145/85 mm Hg. Examination shows a faint abdominal bruit on auscultation. Ultrasonography of the abdomen shows a 4.9-cm saccular dilation of the infrarenal aorta. Which of the following is the most appropriate next step in management?
AElective endovascular aneurysm repair
BAdjustment of cardiovascular risk factors and follow-up ultrasound in 12 months
CAdjustment of cardiovascular risk factors and follow-up ultrasound in 6 months
DElective open aneurysm repair
EAdjustment of cardiovascular risk factors and follow-up CT in 6 months
A 16-year-old boy comes to the physician for a routine health maintenance examination. He feels well. He has no history of serious illness. He is at the 60th percentile for height and weight. Vital signs are within normal limits. The lungs are clear to auscultation. A grade 3/6 ejection systolic murmur is heard along the lower left sternal border. The murmur decreases in intensity on rapid squatting and increases in intensity when he performs the Valsalva maneuver. This patient is at increased risk for which of the following complications?
ASudden cardiac death
BPulmonary apoplexy
CInfective endocarditis
DCerebral aneurysm
EAngiodysplasia
A 27-year-old soldier stationed in Libya sustains a shrapnel injury during an attack, causing a traumatic above-elbow amputation. The resulting arterial bleed is managed with a tourniquet prior to transport to the military treatment facility. On arrival, he is alert and oriented to person, place, and time. His armor and clothing are removed. His pulse is 145/min, respirations are 28/min, and blood pressure is 95/52 mm Hg. Pulmonary examination shows symmetric chest rise. The lungs are clear to auscultation. Abdominal examination shows no abnormalities. There are multiple shrapnel wounds over the upper and lower extremities. A tourniquet is in place around the right upper extremity; the right proximal forearm has been amputated. One large-bore intravenous catheter is placed in the left antecubital fossa. Despite multiple attempts, medical staff is unable to establish additional intravenous access. Which of the following is the most appropriate next step in management?
AIrrigate the shrapnel wounds
BPerform endotracheal intubation
CEstablish intraosseous access
DEstablish central venous access
EReplace the tourniquet with a pressure dressing
