A nurse explains to a client's family that the client's respirations are faster and deeper than normal because of what?
The client is expelling too much carbon dioxide.
The client's blood oxygen level indicates hypoxemia.
The client has developed an inflammation of the phrenic nerve.
The client is using his intercostal muscles to breathe.
The Correct Answer is C
Choice A rationale:
Pulse pressure is the difference between systolic and diastolic blood pressure and is not related to changing positions or the symptoms described in the scenario.
Choice B rationale:
Essential hypertension is a chronic medical condition characterized by elevated blood pressure levels persistently exceeding 140/90 mmHg. It is not directly related to positional changes or postural hypotension symptoms.
Choice C rationale:
Postural (orthostatic) hypotension occurs when a person experiences a sudden drop in blood pressure upon standing up from a sitting or lying position. This drop in blood pressure can lead to symptoms such as dizziness, lightheadedness, and fainting. Slowly changing positions is essential in managing postural hypotension because abrupt movements can worsen these symptoms. Educating the client about the importance of gradual position changes is crucial in preventing or minimizing postural hypotension-related symptoms.
Choice D rationale:
Pre-hypertension refers to blood pressure levels that are higher than normal but not high enough to be diagnosed as hypertension. It does not directly relate to the symptoms described in the scenario.

Correct Answer is ["473"]
Explanation
The correct answer is choice: 473.
To convert 4 ounces to milliliters (mL), the following steps can be taken:
Understand the Conversion Factor: 1 fluid ounce (oz) is approximately 29.57 mL. Therefore, 4 oz can be converted to mL using the following calculation: 4 × 29.57 = 118.28
4oz × 29.57mL/oz = 118.28mL.
Convert Cups to Ounces: 1 cup is equal to 8 fluid ounces.
Therefore, 1 cup is 8 × 29.57= 236.56
8oz × 29.57mL/oz = 236.56mL.
So, 1 cup is equal to 236.56 mL. The correct answer is 473 mL (2 cups)
Correct Answer is A
Explanation
Choice A rationale:
The client's respirations are faster and deeper than normal due to expelling too much carbon dioxide. This condition is known as hyperventilation. Hyperventilation can occur due to various reasons such as anxiety, pain, fever, or metabolic acidosis. When the body expels excessive carbon dioxide, it leads to respiratory alkalosis, resulting in faster and deeper breathing to compensate for the decrease in carbon dioxide levels in the blood.
Choice B rationale:
This option is incorrect. Hypoxemia, or low blood oxygen levels, typically leads to rapid, shallow breathing (tachypnea) rather than deep and fast respirations.
Choice C rationale:
This option is incorrect. Inflammation of the phrenic nerve does not directly affect the depth and rate of respirations. Phrenic nerve inflammation is more likely to cause pain during breathing or hiccups.
Choice D rationale:
This option is incorrect. Using intercostal muscles to breathe is a normal physiological process, especially during deep or labored breathing. However, it does not explain the specific situation described in the question, where the respirations are faster and deeper than normal.
