A patient is diagnosed with primary hypertension and asks the nurse what caused the condition.
Which response would the nurse give?

"There is no identified cause!”

"A decrease in plasma renin levels.”

"Too much plaque in the blood vessels.”

"Kidney disease is the most common cause.”

Answer and Explanation

The Correct Answer is A

Choice B rationale:

A decrease in plasma renin levels is not a known cause of primary hypertension. Primary hypertension often has no identifiable cause, and it is a diagnosis of exclusion.

Choice C rationale:

Too much plaque in the blood vessels describes atherosclerosis, which is a risk factor for hypertension but not the direct cause of primary hypertension. Plaque buildup narrows arteries and increases resistance, contributing to elevated blood pressure.

Choice D rationale:

Kidney disease can cause secondary hypertension but is not the most common cause of primary hypertension. Primary hypertension, also known as essential hypertension, is the most common form, and its exact cause remains unknown in many cases.

Correct Answer is ["C","D"]

Explanation

Choice A rationale:
Increased cobalamin levels are not indicative of polycythemia vera. Polycythemia vera is characterized by an increase in the total red blood cell mass. Elevated cobalamin levels are not specific to this condition.
Choice B rationale:
Decreased histamine levels are not a diagnostic marker for polycythemia vera. Histamine levels are not typically associated with this disorder.
Choice C rationale:
Increased hemoglobin levels are a significant finding in polycythemia vera. Polycythemia vera is a disorder characterized by an abnormal increase in the number of red blood cells, leading to elevated hemoglobin levels.
Choice D rationale:
Increased red blood cell levels are a hallmark feature of polycythemia vera. The increased production of red blood cells leads to elevated red blood cell levels, which is a key diagnostic indicator for this condition.

A. Peripheral arterial disease. B. Lymphatic obstruction. C. Chronic venous insufficiency. D. Musculoskeletal abnormalities.

Correct Answer is A

Explanation

Choice A rationale:

The patient's symptoms of leg pain that worsens at night and occurs when the legs are elevated but improves when they are dangled are indicative of peripheral arterial disease (PAD) PAD is a condition caused by the narrowing of arteries in the legs due to atherosclerosis. This narrowing restricts blood flow to the muscles, causing pain, especially during activities or positions that demand increased blood flow like walking or elevating the legs.

Choice B rationale:

Lymphatic obstruction typically does not cause pain in the same manner described by the patient. Lymphatic obstruction may cause swelling and discomfort, but it usually does not lead to pain that worsens with elevation and improves with dangling.

Choice C rationale:

Chronic venous insufficiency can cause leg pain and swelling, especially when standing for extended periods. However, the characteristic of pain worsening at night and with leg elevation points more towards arterial issues like PAD rather than venous insufficiency.

Choice D rationale:

Musculoskeletal abnormalities could cause localized pain, but the pattern described by the patient (worsening at night, relief with dangling) is not typical of musculoskeletal issues. PAD, on the other hand, often presents with these specific symptoms due to compromised blood flow to the muscles in the legs.
