Questions About the Respiratory System Questions
Question 1 of 5
The nurse is preparing a presentation that highlights the benefits of annual influenza vaccination. The nurse correctly targets which groups Except?
Correct Answer: A
Rationale: The correct answer is A because children aged 3 to 6 months are too young to receive the influenza vaccine. They are not recommended for vaccination until they reach 6 months of age. Choice B is correct as older diabetics are at higher risk for complications from the flu. Choice C is correct as pregnant women are a high-risk group for flu-related complications. Choice D is correct as home health aides are in close contact with vulnerable populations.
Question 2 of 5
The nurse has instructed the client on how to obtain a sputum culture. Which of the statements indicates that the client understood the instruction from the nurse?
Correct Answer: D
Rationale: The correct answer is D because the client demonstrates understanding by acknowledging the need to breathe deeply and cough up the sputum to obtain a sputum culture. This action helps bring up the lower respiratory tract secretions for an accurate culture. Choice A is incorrect because increasing fluids actually helps in sputum production. Choice B is incorrect as mouth care should be done before to prevent contamination. Choice C is incorrect as early morning is the best time due to the accumulation of secretions overnight.
Question 3 of 5
Which of the following substances is activated by passage through the pulmonary circulation?
Correct Answer: D
Rationale: The correct answer is D: Angiotensin 1. When blood passes through the pulmonary circulation, angiotensinogen is converted into angiotensin 1 by the enzyme renin. This activation occurs in the lungs. Bradykinin, serotonin, and noradrenaline are not activated in the pulmonary circulation. Bradykinin is a peptide released during inflammation, serotonin is a neurotransmitter, and noradrenaline is a neurotransmitter and hormone. Therefore, D is the only substance activated by passage through the pulmonary circulation.
Question 4 of 5
A male adult patient hospitalized for treatment of a pulmonary embolism develops respiratory alkalosis. Which clinical findings commonly accompany respiratory alkalosis?
Correct Answer: D
Rationale: The correct answer is D: Lightheadedness or paresthesia. Respiratory alkalosis is caused by hyperventilation, leading to decreased carbon dioxide levels and an increase in pH. This can result in symptoms such as lightheadedness (from decreased cerebral blood flow) and paresthesia (tingling sensations due to changes in calcium ionization). Choices A, B, and C are incorrect as they are not typically associated with respiratory alkalosis. Nausea, vomiting, abdominal pain, and diarrhea are more commonly seen in metabolic alkalosis, while hallucinations and tinnitus are not typical symptoms of respiratory alkalosis.
Question 5 of 5
A nurse is caring for a male client with emphysema who is receiving oxygen. The nurse assesses the oxygen flow rate to ensure that it does not exceed:
Correct Answer: B
Rationale: The correct answer is B: 2 L/min. The rationale is that in emphysema, high oxygen flow rates can cause oxygen toxicity. The recommended maximum flow rate for patients with emphysema is typically 2 L/min to prevent oxygen toxicity. Choice A (1 L/min) may not provide sufficient oxygen, choice C (6 L/min) and choice D (10 L/min) are too high and can lead to oxygen toxicity in patients with emphysema. Therefore, choice B is the most appropriate and safe option for this client.
