Multiple Choice Questions for Respiratory System Questions
Question 1 of 5
The cartilage which are triangular pieces of hyaline cartilage and influence the position and tension of vocal cords?
Correct Answer: B
Rationale: The correct answer is B: paired arytenoid cartilage. These cartilages are triangular and play a crucial role in adjusting the tension and position of the vocal cords, thus affecting voice pitch and quality. The thyroid cartilage (A) is a large shield-shaped cartilage, the corniculate cartilage (C) is small and horn-shaped, and the cricoid cartilage (D) is a ring-shaped cartilage. These cartilages do not directly influence the vocal cords' tension and position.
Question 2 of 5
After using a nasal cannula delivery system at 3 L/min, a patient with chronic airflow limitation (CAL) changes to a simple face mask. The nasal equipment oxygen was set at 3 L/min. How should the nurse adjust the oxygen flow for the new delivery system?
Correct Answer: D
Rationale: To determine the correct oxygen flow for a simple face mask, you should increase it from the previous nasal cannula rate. As simple face masks deliver oxygen less efficiently, a higher flow rate is needed to maintain the same oxygen concentration. Moving from 3 L/min nasal cannula to a simple face mask, you should increase the flow to 6 L/min to ensure adequate oxygen delivery to the patient with chronic airflow limitation. Choices A and B are incorrect as decreasing or keeping the flow the same would not provide sufficient oxygen. Choice C is also incorrect as increasing it to 4 L/min may not be enough to compensate for the decreased efficiency of the simple face mask.
Question 3 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 4 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 5 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.
