A female patient with chronic hypertension is admitted to the emergency department with a sudden rise in blood pressure (BP) Which question is the priority for the nurse to ask the patient?
"Are you pregnant?”
"Do you need to urinate?”
"Do you have a headache or confusion?”
"Are you taking antiseizure medications?”
The Correct Answer is C
Choice A rationale:
While pregnancy can contribute to increased blood pressure, it is not the priority question in this scenario. The sudden rise in blood pressure could indicate a hypertensive crisis, which needs immediate attention.
Choice B rationale:
Urination is not directly related to sudden rises in blood pressure. While urinary issues could be a sign of certain conditions, they are not the priority when dealing with a hypertensive emergency.
Choice C rationale:
A sudden rise in blood pressure can lead to symptoms such as headache and confusion, which could indicate a hypertensive crisis. This question is crucial to assess neurological symptoms, which can be indicative of target organ damage due to hypertension.
Choice D rationale:
Antiseizure medications are not directly related to sudden increases in blood pressure. Neurological symptoms (like those in choice C) are more indicative of a hypertensive crisis and require immediate attention.

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.
Correct Answer is C
Explanation
Choice A rationale:
Buffers do not excrete weak acids; instead, they help regulate the pH of bodily fluids by preventing drastic changes in acidity or alkalinity.
Choice B rationale:
Buffers do not secrete hydrogen ions. In fact, buffers can either absorb or release hydrogen ions to maintain a stable pH.
Choice C rationale:
To convert strong acids to weak acids is the correct answer. Buffers are substances that can neutralize both acids and bases, helping to maintain a stable pH in a solution. They achieve this by accepting hydrogen ions from strong acids or donating hydrogen ions to strong bases, converting them into weaker acids or bases, respectively.
Choice D rationale:
Buffers do not convert ammonia to ammonium ions. This conversion is a part of the body's acid-base regulation system, but it is not the primary function of buffers.
