Her right carotid pulse is bounding but the left carotid pulse is weak. She is afebrile but her respirations are 24 times a minute. On auscultation her lungs are clear and her cardiac examination is unremarkable. You call EMS and have her taken to the hospital's ER for further evaluation. What disorder of the chest best describes her symptoms?

Correct Answer: C

Rationale: A dissecting aortic aneurysm is the most likely disorder that best describes the symptoms presented. In this condition, the inner layer of the aorta tears and blood can flow between the layers of the aortic wall, causing a number of potential symptoms. A patient with a dissecting aortic aneurysm may present with a difference in pulses between the right and left sides due to decreased blood flow to one side. The bounding pulse on one side and weak pulse on the other are indicative of uneven blood flow distribution. Additionally, a dissecting aortic aneurysm can lead to respiratory symptoms such as increased respiratory rate if there is associated pain or discomfort, although clear lung sounds would not typically be expected with this condition. The condition is a life-threatening emergency that requires immediate evaluation and treatment.

Correct Answer: B

Rationale: Peripheral arterial disease (PAD) is considered a coronary heart disease risk equivalent, meaning it confers a similar risk as having a history of coronary heart disease itself. Individuals with PAD have a significantly increased risk of cardiovascular events such as heart attack and stroke. Therefore, when assessing the 10-year coronary heart disease risk of the 40-year-old banker, having peripheral arterial disease would be a crucial factor to consider in addition to other risk factors like hypertension, exercise habits, and smoking history.

Correct Answer: B

Rationale: Jugular venous pressure (JVP) is measured as the vertical height of the blood column in centimeters above the sternal angle (Angle of Louis). To measure the JVP accurately, the patient should be positioned at a 30-45 degree angle (not 45-degree angle as in choice A). The value obtained by measuring the JVP in centimeters is then added to 5 cm, which represents the distance from the sternal angle to the right atrium. Therefore, the formula for calculating JVP is the vertical height of the blood column in cm + 5 cm. A JVP below 9 cm (not 9 cm or choice C) is generally considered normal, while a JVP above that level is considered elevated. It is important to measure the JVP correctly and interpret the findings in the context of the patient's

Correct Answer: A

Rationale: In hyperthyroidism, there is an increased metabolic rate and sympathetic activity. This can lead to increased cardiac output and left ventricular mass, causing the heart to work harder. As a result, the left ventricle becomes hypertrophied, leading to a sustained, high-amplitude Point of Maximum Impulse (PMI) that is displaced laterally and downward. This can be felt during a physical examination as a strong and forceful PMI. In contrast, conditions like anemia, fever, and hypertension are not typically associated with a sustained, high-amplitude PMI.

Correct Answer: C

Rationale: It is recommended for women to conduct breast self-examination immediately prior to their menses. This is because the breasts are less likely to be tender, lumpy, or swollen during this time of the menstrual cycle, making it easier to detect any abnormalities such as lumps or changes in the breast tissue. Conducting breast self-examination around this time each month can help women become familiar with the normal look and feel of their breasts, making it easier to detect any changes that may indicate a potential issue.
