Multiple Choice Questions About Respiratory System Questions
Question 1 of 5
Wall of Larynx is supported by the cartilage
Correct Answer: D
Rationale: The correct answer is D, All these. The wall of the larynx is supported by a combination of cartilages, including the cricoid, thyroid, and arytenoid cartilages. The cricoid cartilage forms the base of the larynx, the thyroid cartilage forms the front and sides, and the arytenoid cartilages sit on top of the cricoid and are involved in vocal cord movement. Each of these cartilages plays a crucial role in supporting and maintaining the structure and function of the larynx. Therefore, all of these cartilages collectively support the wall of the larynx. Choices A, B, and C are incorrect because each of these cartilages individually contributes to the support of the larynx, but it is the combination of all three that fully supports the wall of the larynx.
Question 2 of 5
Pinnaglobin is a brown coloured blood pigment present in the plasma of the mollusk Pinna. It contains
Correct Answer: B
Rationale: The correct answer is B: Copper. Pinnaglobin is a copper-containing blood pigment found in the plasma of the mollusk Pinna. Copper ions are essential for the formation of this pigment. Iron (Choice A), Manganese (Choice C), and Vanadium (Choice D) are not typically found in Pinnaglobin. Iron is commonly associated with hemoglobin in vertebrates, while manganese and vanadium do not play a significant role in mollusk blood pigments. Therefore, the presence of copper in Pinnaglobin makes Choice B the correct answer.
Question 3 of 5
The nurse is assessing a newly admitted medical patient and notes there is a depression in the lower portion of the patient's sternum. This patient's health record should note the presence of what chest deformity?
Correct Answer: B
Rationale: The correct answer is B: A funnel chest. A funnel chest, also known as pectus excavatum, is characterized by a depression in the lower portion of the sternum. This deformity causes the chest to appear sunken or caved in. The other choices are incorrect because: A) A barrel chest is associated with COPD and is characterized by an increased anterior-posterior diameter of the chest. C) A pigeon chest, also known as pectus carinatum, is characterized by a protrusion of the sternum and ribs. D) Kyphoscoliosis is a combination of kyphosis and scoliosis, involving both a curvature of the spine and rotation of the vertebrae.
Question 4 of 5
A medical patient rings her call bell and expresses alarm to the nurse, stating, 'I've just coughed up this blood. That can't be good, can it?' How can the nurse best determine whether the source of the blood was the patient's lungs?
Correct Answer: B
Rationale: The correct answer is B: Try to see if the blood is frothy or mixed with mucus. By observing if the blood is frothy or mixed with mucus, the nurse can determine if the source is more likely to be from the lungs, as blood from the lungs is often frothy due to air mixing with it during coughing. This observation helps differentiate between blood coming from the respiratory tract versus other sources in the body. Incorrect choices: A: Testing the pH of the blood does not directly indicate the source of the blood in this context. C: Performing oral suctioning may not provide accurate information about the source of the blood. D: Swabbing the back of the throat may not help determine if the blood is coming from the lungs as it could be from other sources in the upper respiratory tract.
Question 5 of 5
Lungs are held tightly to the wall of the thorax due to
Correct Answer: C
Rationale: The correct answer is C because the surface tension of the pleural fluid creates a cohesive force that keeps the lungs adhered to the thoracic wall. This, combined with the negative pressure in the pleural cavity, creates a vacuum effect that maintains the lungs' position. A) The diaphragm and intercostal muscle contractions help with breathing but do not directly secure the lungs to the thorax. B) Tight junctions between the lungs and thorax do not play a significant role in holding the lungs in place. D) Atmospheric pressure does not hold the lungs against the thoracic wall; rather, it helps with breathing by aiding in lung expansion and contraction.
