Multiple Choice Questions About Respiratory System Questions
Question 1 of 5
The abnormal assessment findings of dullness and hyperresonance are found with which assessment technique?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 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 3 of 5
Bohr effect shifts the O2 Hb dissociation curve to right
Correct Answer: D
Rationale: The Bohr effect states that a decrease in pH shifts the oxygen-hemoglobin dissociation curve to the right, promoting the release of oxygen to tissues. This occurs in metabolically active tissues where CO2 is produced, lowering the pH. Choice D is correct because a decrease in blood pH facilitates oxygen unloading. Choices A and B are incorrect because the Bohr effect is related to oxygen release, not uptake. Choice C is incorrect because decreasing CO2 concentration would actually shift the curve to the left.
Question 4 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 5 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.
