What organ is contained in the cranial cavity?
Spinal cord.
Heart.
Brain.
Stomach.
The Correct Answer is C
Choice A rationale:
The spinal cord is not contained in the cranial cavity. The spinal cord is located within the spinal canal, which runs through the vertebral column, providing protection to the spinal cord.
Choice B rationale:
The heart is not contained in the cranial cavity. The heart is situated in the thoracic cavity, between the lungs, and is protected by the ribcage.
Choice C rationale:
The brain is contained in the cranial cavity. The cranial cavity, also known as the intracranial space, houses the brain and provides protection to this vital organ. The brain is the control center of the body, regulating various functions and processing sensory information.
Choice D rationale:
The stomach is not contained in the cranial cavity. The stomach is located in the abdominal cavity, which is situated below the diaphragm and above the pelvis. It is involved in the digestion of food and is not found in the cranial cavity.

Correct Answer is B
Explanation
Choice A rationale:
Obtaining the blood pressure first thing in the morning is not the most critical factor in accurately measuring blood pressure. Blood pressure can vary throughout the day due to various factors, and it is essential to use the appropriate technique and equipment at any time of the day.
Choice B rationale:
Using the appropriate size cuff for the client is crucial in obtaining an accurate blood pressure reading. If the cuff is too small, it can lead to falsely elevated blood pressure readings, while a cuff that is too large can result in falsely lowered readings. This is because cuff size affects the pressure applied to the artery during measurement.
Choice C rationale:
Ensuring that the client is relaxed and comfortable prior to obtaining the blood pressure is important but not the most critical factor. Anxiety or discomfort can temporarily elevate blood pressure, so it's essential to create a calm and comfortable environment for the client. However, using the correct cuff size is still more critical for accurate measurements.
Choice D rationale:
Removing clothing from the arms before obtaining blood pressure is not the most important action. While it is generally recommended to expose the client's arm for proper cuff placement, it is secondary to using the appropriate cuff size. The cuff should be placed directly on the skin or over a thin layer of clothing, but this step should not take precedence over cuff size selection.
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.
