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. Palpitations. B. Conjunctival pallor. C. Sternal tenderness. D. Heart rate of 104 beats/min.

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

Explanation

Choice A rationale:

Palpitations are not directly related to a low hemoglobin level. They can occur due to various cardiac conditions but are not specific to anemia.

Choice B rationale:

Conjunctival pallor is a common physical finding in patients with low hemoglobin levels (anemia) Anemia leads to reduced oxygen-carrying capacity, causing paleness in mucous membranes such as the conjunctiva.

Choice C rationale:

Sternal tenderness is not a typical finding associated with low hemoglobin levels. It is more often associated with conditions affecting the sternum or adjacent structures, such as infections or inflammation.

Choice D rationale:

A heart rate of 104 beats/min can be a compensatory response to anemia. When the body senses reduced oxygen levels due to anemia, the heart rate may increase to pump more blood and oxygen to vital organs, attempting to compensate for the low hemoglobin levels.
