Respiratory System Questions and Answers PDF Questions
Question 1 of 5
Rhea, confused and short breath, is brought to the emergency department by a family member. The medical history reveals chronic bronchitis and hypertension. To learn more about the current respiratory problem, the doctor orders a chest x-ray and arterial blood gas (ABG) analysis. When reviewing the ABG report, the nurses see many abbreviations. What does a lowercase in ABG value present?
Correct Answer: B
Rationale: The correct answer is B: Arterial Blood. The lowercase "a" in ABG values denotes arterial blood, indicating that the values are specific to the blood obtained from an artery. ABG analysis provides information about the oxygen and carbon dioxide levels in the blood, as well as the pH and bicarbonate levels, which are crucial in assessing respiratory and metabolic functions. Choice A: Acid-base balance - This is incorrect because the lowercase "a" in ABG does not represent acid-base balance. Acid-base balance is determined by the pH level in the blood, which is one of the parameters measured in ABG analysis. Choice C: Arterial oxygen saturation - This is incorrect because oxygen saturation is typically measured using pulse oximetry, not through ABG analysis. ABG values focus on the partial pressure of oxygen in the arterial blood. Choice D: Alveoli - This is incorrect because ABG values do not directly represent the condition of the alveoli. ABG analysis
Question 2 of 5
A nurse is preparing to obtain a sputum specimen from a client. Which of the following nursing actions will facilitate obtaining the specimen?
Correct Answer: B
Rationale: Step 1: Taking deep breaths helps to bring sputum up from the lungs. Step 2: Coughing deeply helps to further bring sputum up. Step 3: This action facilitates the collection of a good sputum specimen. Step 4: Limiting fluids can make sputum thicker and harder to expectorate. Step 5: Asking the client to spit may result in saliva instead of sputum. Step 6: Asking for a specimen after eating can lead to contamination.
Question 3 of 5
Which of the following instructions should the nurse give a client about his active tuberculosis (TB)?
Correct Answer: D
Rationale: The correct answer is D because adherence to the medication regimen is crucial in treating active TB to prevent drug resistance and ensure successful treatment. Missing doses can lead to treatment failure and the spread of TB. Option A is incorrect because missing doses compromises treatment effectiveness. Option B is incorrect as stopping medication due to side effects can also result in treatment failure. Option C is incorrect because TB treatment must be completed as prescribed, regardless of symptom improvement.
Question 4 of 5
The atmospheric pressure at sea level is
Correct Answer: B
Rationale: The atmospheric pressure at sea level is typically around 760mm Hg, which is equivalent to 101.3 kilopascals. This is the standard atmospheric pressure used in various scientific calculations. This value represents the pressure exerted by the weight of air above a given area at sea level. Choice B is correct because it accurately reflects the standard atmospheric pressure at sea level. Choices A, C, and D are incorrect as they do not match the accepted value for atmospheric pressure at sea level.
Question 5 of 5
Although carbon dioxide is normally carried by hemoglobin, the fact that carbon monoxide reduces hemoglobin's oxygen-carrying capacity would indicate that
Correct Answer: B
Rationale: The correct answer is B because carbon monoxide competes with oxygen for the same binding sites on hemoglobin, leading to reduced oxygen-carrying capacity. This is known as competitive inhibition. Other choices are incorrect because different hemoglobins do not carry different gases (A), binding of gases is not directed by enzymes in this context (C), and carbon dioxide is a normal gas in the body (D).
