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 B
Explanation
Choice A rationale:
The base does interact with acids in the acid-base balance. Bases, by definition, are substances that can accept hydrogen ions (protons) and neutralize acids. In the context of acid-base balance, bases help regulate the pH of body fluids by counteracting the effects of acids.
Choice B rationale:
The role of the base in the acid-base balance is to promote the excretion of acid. Bicarbonate ions (HCO3-) are a vital component of the body's buffering system, helping to neutralize excess acid. The kidneys play a crucial role in excreting acids from the body, maintaining the acid-base balance.
Choice C rationale:
The base does not activate the system of acid-base balance; instead, it is part of the body's natural buffering system. The acid-base balance is regulated by the lungs and kidneys, which work together to maintain the pH of body fluids within a narrow range (7.35-7.45)
Choice D rationale:
Bases do not increase the action of hydrogen ions. In fact, bases neutralize hydrogen ions, which are acidic. By accepting these ions, bases help to decrease the acidity of a solution, playing a key role in maintaining the body's acid-base balance.
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.
