Questions on Respiratory System Questions
Question 1 of 5
The last mammalian structure that air moves through before the alveoli is the
Correct Answer: C
Rationale: The correct answer is C: bronchioles. After air passes through the trachea, it enters the bronchi, which further divide into bronchioles. The bronchioles are the last structures where air passes before reaching the alveoli for gas exchange. The larynx is involved in sound production and the glottis is the opening between the vocal cords in the larynx. While the trachea is the initial passage for air into the respiratory system, the bronchioles are the final branching structures where air reaches the alveoli, making them the correct answer.
Question 2 of 5
Which of the following describes a correct order of structures in the respiratory passageways?
Correct Answer: D
Rationale: The correct order of structures in the respiratory passageways is D: pharynx, larynx, trachea, bronchi, bronchioles. This is the correct order because air enters the body through the pharynx, then passes through the larynx (voice box), followed by the trachea (windpipe), which branches into the bronchi, and then further divides into bronchioles. The other choices are incorrect because they do not follow the natural flow of air through the respiratory system. Choice A has the incorrect order starting with the pharynx, followed by the trachea, larynx, bronchi, and bronchioles. Choice B starts with the larynx, then pharynx, trachea, bronchioles, and bronchi, which is out of sequence. Choice C begins with the trachea, then pharynx, larynx, bronchi, and bronchioles, which is also incorrect
Question 3 of 5
Inflammation of the lungs covering causing severe chest pain is
Correct Answer: B
Rationale: The correct answer is B: Pleurisy. Pleurisy is inflammation of the pleura, the lining around the lungs, causing severe chest pain. Emphysema (A) is a chronic lung condition causing shortness of breath, not chest pain. Asphyxia (C) is a condition of insufficient oxygen, not related to lung inflammation. Hypoxia (D) is low oxygen levels in tissues, not specific to lung covering inflammation. Pleurisy is the only choice directly related to inflammation of the lungs' covering, making it the correct answer.
Question 4 of 5
The metal associated with haemoglobin is
Correct Answer: D
Rationale: The correct answer is D: Iron. Haemoglobin is a protein in red blood cells that carries oxygen throughout the body. Iron is an essential component of haemoglobin, binding to oxygen molecules and facilitating their transport. Sodium, potassium, and calcium do not play a direct role in the structure or function of haemoglobin, making them incorrect choices. Iron deficiency can lead to anemia due to the lack of adequate oxygen-carrying capacity in the blood.
Question 5 of 5
An assistive personnel (AP) was feeding a client with a tracheostomy. Later that evening the UAP reports that the client had a coughing spell during the meal. What action by the nurse is best?
Correct Answer: A
Rationale: Correct Answer: A - Assess the client's lung sounds. Rationale: 1. Assessing lung sounds helps determine if the client is experiencing respiratory distress. 2. Coughing during a meal with a tracheostomy can indicate aspiration or airway obstruction. 3. Prompt assessment can prevent potential complications and guide further interventions. Summary: - B: Assigning a different AP does not address the client's immediate respiratory status. - C: Reporting the AP to the manager is not necessary before assessing the client's condition. - D: Requesting thicker liquids does not address the underlying issue of potential aspiration or airway obstruction.
