Multiple Choice Questions for Respiratory System Questions
Question 1 of 5
oropharynx contain
Correct Answer: D
Rationale: The correct answer is D because the oropharynx contains both palatine tonsils (choice A) and lingual tonsils (choice B). Palatine tonsils are located on the sides of the oropharynx and lingual tonsils are located at the base of the tongue. Pharyngeal tonsils (choice C) are also known as adenoids and are located in the nasopharynx, not the oropharynx. Therefore, choices A, B, and C alone are incorrect. Choice D is correct because both palatine tonsils and lingual tonsils are present in the oropharynx.
Question 2 of 5
After the nurse teaches the client with stage 1 hypertension about diet modifications.Which diet choice indicates that the teaching has been most effective?
Correct Answer: A
Rationale: The correct answer is A because avoiding salted nuts helps reduce sodium intake, which is crucial for managing hypertension. Salt can increase blood pressure. Choice B is incorrect as chicken and fish can be part of a healthy diet. Choice C is incorrect as sugary beverages can worsen hypertension. Choice D is incorrect as excessive caffeine intake can raise blood pressure. In summary, choice A is the most effective as it directly addresses reducing sodium intake, which is essential for managing hypertension.
Question 3 of 5
A client who has chronic heart failure is admitted to the emergency department with severe dyspnea and a dry hacking cough. Which action should the nurse take first?
Correct Answer: C
Rationale: The correct action for the nurse to take first is to auscultate the breath sounds (Choice C) because the client is presenting with severe dyspnea and a dry hacking cough, which are indicative of respiratory distress in a patient with chronic heart failure. Auscultating the breath sounds will help the nurse assess the presence of crackles, wheezing, or decreased air entry, providing crucial information about the client's respiratory status and guiding immediate interventions. Checking the capillary refill (Choice B) is important but not the priority in this situation. Auscultating the abdomen (Choice A) is not relevant to the presenting symptoms. Asking about the patient's allergies (Choice D) is important but can be addressed after addressing the immediate respiratory distress.
Question 4 of 5
Identify the inconsistent value in these measurements on a mixed venous blood sample obtained in a healthy person from IVC at sea level
Correct Answer: C
Rationale: The correct answer is C: PN2 = 620mmHg. This is the inconsistent value because the normal partial pressure of nitrogen in venous blood is around 40 mmHg, not 620 mmHg. This discrepancy indicates an abnormal measurement. The other choices (A, B, D) are within expected ranges for a mixed venous blood sample in a healthy person at sea level. Choice A (pO2 = 40mmHg) is typical for venous blood, choice B (pCO2 = 48mmHg) falls within the normal range, and choice D (O2 content = 150ml/L blood) is a reasonable value for mixed venous blood.
Question 5 of 5
Of the four parts of respiration the part when oxygen and carbon dioxide are exchanged in the capillaries lining the alveoli in the lungs is:
Correct Answer: B
Rationale: The correct answer is B: external respiration. This is the part of respiration where oxygen and carbon dioxide are exchanged in the capillaries lining the alveoli in the lungs. During external respiration, oxygen from the alveoli diffuses into the bloodstream while carbon dioxide from the bloodstream diffuses into the alveoli to be exhaled. A: Pulmonary ventilation refers to the process of breathing, specifically the movement of air in and out of the lungs. This does not involve the actual exchange of gases in the alveoli. C: Transport of respiratory gases involves the movement of oxygen and carbon dioxide through the bloodstream to and from the tissues. This is not specifically related to the exchange of gases in the alveoli. D: Internal respiration refers to the exchange of gases between the bloodstream and the tissues at the cellular level. This does not specifically occur in the alveoli of the lungs.
