What controls the rate and depth of respiration in a normal adult?
Chemoreceptors in response to the acid-base and oxygen status.
The amount of stretch and elastic recoil in the lung muscles.
Feedback from cells in peripheral parts of the body during activity.
The percentage of oxygen available compared to the amount required by the brain.
The Correct Answer is A
The rate and depth of respiration in a normal adult are primarily controlled by chemoreceptors. These receptors monitor the levels of carbon dioxide (CO₂), oxygen (O₂), and the pH (acid-base balance) of the blood. They send signals to the respiratory centers in the brain to adjust breathing accordingly to maintain homeostasis.

Correct Answer is A
Explanation
The frontal lobe of the brain is responsible for controlling thoughts, plans, and behavior. It is involved in executive functions such as decision-making, problem-solving, planning, and controlling voluntary movements.
Correct Answer is ["B","C","D"]
Explanation
Choice A reason:
Canceling Netflix by Internet service is not relevant to Mr. Jones’ discharge planning. While managing finances and subscriptions may be part of overall life management, it does not address the immediate safety and mental health needs of Mr. Jones.
Choice B reason:
Releasing information signed for family to secure Mr. Jones’ loaded gun or having the police secure the gun if needed prior to discharge is crucial for ensuring his safety. Removing access to firearms reduces the risk of self-harm and is an important step in discharge planning for someone with suicidal ideation.
Choice C reason:
Obtaining a psychiatric provider follow-up appointment as soon as possible and evaluating for PHP (Partial Hospitalization Program) or residential treatment with the treatment team is essential. Continuity of care and appropriate follow-up are critical for managing Mr. Jones’ depression and preventing relapse.
Choice D reason:
Assisting in developing a safety plan prior to discharge that is written with phone numbers and interventions is vital. A safety plan provides Mr. Jones with clear steps to take if he feels at risk of harming himself, including contact information for crisis services and supportive individuals.
