Questions on Respiratory System Questions
Question 1 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 2 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 3 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.
Question 4 of 5
The nurse is teaching a client with obstructive sleep apnea (OSA) about the prescribed CPAP. What information does the nurse NOT include?
Correct Answer: A
Rationale: The correct answer is A because insurance coverage for CPAP machines is generally not based on the number of hours it is worn per day but rather on medical necessity. The nurse would not include this information as it could lead to misunderstanding and incorrect assumptions. Choice B is incorrect because adjusting the mask may be necessary for comfort. Choice C is correct as CPAP does provide pressure to keep airways open. Choice D is also correct as cleaning the mask regularly is essential to prevent infections.
Question 5 of 5
Sputum specimens are examined to detect which of the following?
Correct Answer: B
Rationale: The correct answer is B. Sputum specimens are often examined for cancer cells in cases of suspected lung cancer. While foreign bodies (A) can sometimes be identified, they are less common in routine sputum analysis. Pulmonary emboli (C) cannot be detected via sputum examination; imaging studies are required. Inflammation (D) may be inferred from white blood cell counts, but detecting cancer cells is more specific and clinically significant.
