Respiratory System Questions Questions
Question 1 of 5
You observe the nurse perform all of these actions. For which action must you intervene immediately?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
Which obstructive pulmonary disease would a 30-year-old white female patient with a parent with the disease be most likely to be diagnosed with?
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
A nurse assesses a client after an open lung biopsy. Which assessment finding is matched with the correct intervention?
Correct Answer: C
Rationale: The correct answer is C because reduced breath sounds after an open lung biopsy may indicate a pneumothorax, a serious complication requiring immediate attention. Calling the physician allows for prompt assessment and intervention. A: Oxygen and pulse oximetry are not the appropriate interventions for dizziness. B: Withholding pain medication based solely on heart rate is not indicated without further assessment. D: Decreasing oxygen flow rate when the respiratory rate is within normal range is unnecessary and may compromise oxygenation.
Question 4 of 5
Respiratory Quotient is not less than one in
Correct Answer: A
Rationale: The Respiratory Quotient (RQ) is the ratio of CO2 produced to O2 consumed during metabolism. For carbohydrates, RQ is always equal to or greater than 1 because they are completely oxidized to CO2 and H2O. Proteins and fats have RQ values less than 1 as they may not be fully oxidized. Normal diet consists of a mix of carbohydrates, proteins, and fats, so the RQ can vary. Therefore, the correct answer is A (Carbohydrates) because they have an RQ not less than one due to complete oxidation. Proteins and fats (choices B and C) have RQ values less than one, and the RQ for a normal diet (choice D) can't be generalized as it includes a mix of nutrients.
Question 5 of 5
At high altitude, the number of RBC increases
Correct Answer: B
Rationale: Step 1: High altitude has lower oxygen levels, causing oxygen deficiency. Step 2: The body adapts to this by increasing the number of red blood cells (RBC). Step 3: More RBCs enhance oxygen-carrying capacity, aiding in oxygen delivery. Step 4: Choice B is correct as it accurately describes the physiological response to high altitude. Summary: A: Incorrect. RBCs increase to enhance oxygen uptake, not trap oxygen. C: Incorrect. RBCs do not increase to remove more CO2 at high altitudes. D: Incorrect. RBC increase is primarily to compensate for oxygen deficiency, not to increase metabolism.
