Risk factors for stroke include: (Select All That Apply)

Choice A rationale

While secondary hypertension can cause organ damage if left untreated, this is not its defining characteristic. Both primary and secondary hypertension can lead to complications like stroke, kidney failure, and heart disease. The distinguishing factor of secondary hypertension is its etiology rather than its severity. Organ damage is often more a function of the duration and magnitude of the blood pressure elevation rather than whether the underlying cause is identified or is considered to be idiopathic in nature.

Choice B rationale

This statement describes primary or essential hypertension, which accounts for about 90 to 95 percent of all hypertension cases. Primary hypertension has no single identifiable cause and is thought to result from a complex interaction of genetics and lifestyle factors. Secondary hypertension, by definition, has a specific, identifiable underlying cause. Common causes of secondary hypertension include chronic kidney disease, primary aldosteronism, renovascular disease, sleep apnea, or certain medications like oral contraceptives and nonsteroidal anti-inflammatory drugs.

Choice C rationale

Secondary hypertension is high blood pressure that is caused by another medical condition. Because it is a symptom of an underlying issue, treating that specific condition often results in the blood pressure returning to normal or becoming much easier to manage. For example, if a patient has a pheochromocytoma, removing the tumor usually cures the hypertension. This distinguishes it from essential hypertension, which requires lifelong management with lifestyle changes and medications because the root cause cannot be definitively removed.

Choice D rationale

The term silent killer is used to describe hypertension in general, both primary and secondary, because it often has no obvious symptoms while it causes progressive damage to the cardiovascular system. Patients can have dangerously high blood pressure for years without feeling any different. However, this nickname does not specifically define what secondary hypertension is or how it differs from the primary form. The focus of the term is on the asymptomatic nature of high blood pressure rather than its underlying cause.

Choice A rationale

Myocardial infarction involves ischemia and necrosis of the heart muscle, often presenting with chest pain that may radiate to the left arm or jaw. While epigastric pain can occur, the negative electrocardiogram and normal cardiac enzymes (such as Troponin I < 0.04 ng/mL) significantly lower the probability of a cardiac event. The specific trigger of a high-fat meal and radiation to the back is much more characteristic of gallbladder disease than coronary occlusion.

Choice B rationale

Cholecystitis is inflammation of the gallbladder, often caused by gallstones obstructing the cystic duct. High-fat meals trigger the release of cholecystokinin, which causes the gallbladder to contract to release bile. If obstructed, this contraction causes sharp pain in the right upper quadrant that frequently radiates to the right scapula or back. This classic presentation, combined with the lack of cardiac markers and the dietary trigger, strongly suggests the gallbladder is the source of the pain.

Choice C rationale

Gastroesophageal reflux occurs when stomach acid backs up into the esophagus, causing a burning sensation in the chest known as heartburn. While it is often triggered by eating, it typically causes retrosternal burning rather than sharp right upper quadrant pain that radiates to the back. Reflux does not usually present with the severity and specific radiation pattern seen in biliary colic or cholecystitis, making it a less likely primary diagnosis for this specific patient.

Choice D rationale

Appendicitis is the inflammation of the vermiform appendix, typically presenting with periumbilical pain that later localizes to the right lower quadrant at McBurney's point. While it can cause nausea and vomiting, the pain is not usually triggered specifically by high-fat meals, nor does it typically radiate to the back from the right upper quadrant. The anatomical location of the pain in this scenario is too high for a standard presentation of acute appendicitis.
