Respiratory Disorders NCLEX Quiz

Respiratory Disorders NCLEX Practice Question.

The respiratory system functions primarily to maintain the exchange of oxygen and carbon dioxide in the lungs and tissues and to regulate acid-base balance. Any change in this system affects every other body system. Conversely, changes in other body systems may reduce the lungs’ ability to provide oxygen and eliminate carbon dioxide.

Following 10 Practice Questions are based on Respiratory Disorders.

Respiratory Disirder includes the following.

  • Tonsillitis
  • Laryngitis
  • Common coldBronchitis
  • Pneumonia
  • Pleurisy
  • Emphysema
  • Cystic fibrosis
  • Asthma
  • Lung cancer

The respiratory system consists of the airways, lungs, bony thorax, and respiratory muscles and functions in conjunction with the central nervous system (CNS).



The airways are divided into the upper and lower airways. The upper airways include the nasopharynx (nose), oropharynx (mouth), laryngopharynx, and larynx. Their purpose is to warm, filter, and humidify inhaled air. They also help make sound and send air to the lower airways.


Each lung is wrapped in a lining called the visceral pleura. The larger of the two lungs, the right lung has three lobes: upper, middle, and lower. The smaller left lung has only an upper and a lower lobe.

The bony thorax includes the clavicles, sternum, scapula, 12 sets of ribs, and 12 thoracic vertebrae. You can use specific parts of the thorax, along with some imaginary vertical lines drawn on the Ribs are made of bone and cartilage and allow the chest to expand and contract during each breath. All ribs attach to the vertebrae.
The first seven ribs also attach directly to the sternum. The 8th, 9th, and 10th ribs attach to the costal cartilage of the ribs above. The 11th and 12th ribs are called floating ribs because they don’t attach to anything in the front.

Respiratory muscles:

The diaphragm and the external intercostal muscles are the primary muscles used in breathing. They contract when the patient inhales and relax when the patient exhales. The respiratory center in the medulla initiates each breath by sending messages to the primary respiratory muscles over the phrenic nerve. Impulses from
the phrenic nerve adjust the rate and depth of breathing, depending on the carbon dioxide and pH levels in the cerebrospinal fluid (CSF).
