NCLEX RN Questions on Respiratory System Questions
Question 1 of 5
Client history and assessment reveals all of these findings. Which finding supports the diagnosis of PE?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
What is the most effective treatment for cystic fibrosis?
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
Inflammation of the lung covering causing severe chest pain is
Correct Answer: B
Rationale: The correct answer is B: Pleurisy. Pleurisy is the inflammation of the lung covering (pleura), leading to severe chest pain. Emphysema (A) is a chronic lung disease characterized by damaged air sacs. Asphyxia (C) is a condition of inadequate oxygen supply. Hypoxia (D) is a state of low oxygen levels in tissues. Pleurisy is the best fit as it directly relates to inflammation of the lung covering and severe chest pain.
Question 4 of 5
Double Bohr effect (Oxygen curves for maternal and foetal Hb move apart in opposite directions) occurs in
Correct Answer: C
Rationale: Rationale: 1. In the placenta, maternal and fetal blood circulations are in close proximity. 2. Maternal Hb releases oxygen to fetal Hb due to the lower affinity of fetal Hb for oxygen. 3. This double Bohr effect causes the oxygen dissociation curves of maternal and fetal Hb to move apart. 4. This occurs specifically in the placenta where both maternal and fetal circulations operate. Summary: A. Incorrect. Double Bohr effect doesn't occur solely in fetal circulation. B. Incorrect. Double Bohr effect doesn't occur solely in maternal circulation. C. Correct. Placenta facilitates the exchange between maternal and fetal blood causing the double Bohr effect. D. Incorrect. Double Bohr effect is not related to the uterine wall.
Question 5 of 5
Spirometry is used
Correct Answer: B
Rationale: The correct answer is B: To detect the air flow through the respiratory system. Spirometry measures lung function by assessing the volume of air inhaled and exhaled. It helps in diagnosing respiratory conditions like asthma or COPD. Choice A is incorrect because spirometry does not measure hemoglobin levels. Choice C is incorrect as spirometry does not determine the respiratory quotient, which relates to metabolic processes. Choice D is incorrect as spirometry is used for assessing respiratory function.
