NCLEX RN Questions on Respiratory System Questions
Question 1 of 5
When obtaining a health history from a 76-year-old patient with suspected CAP, what does the nurse expect the patient or caregiver to report?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 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 3 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 4 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.
Question 5 of 5
While assessing an acutely ill patient's respiratory rate, the nurse assesses four normal breaths followed by an episode of apnea lasting 20 seconds. How should the nurse document this finding?
Correct Answer: C
Rationale: The correct answer is C: Biot's respiration. Biot's respiration is characterized by regular breathing interrupted by periods of apnea. In this scenario, the nurse observed normal breaths followed by a 20-second episode of apnea, which aligns with Biot's respiration. It is crucial to document this finding accurately to ensure appropriate care. Incorrect answers: A: Eupnea refers to normal breathing without any interruptions or irregularities. The presence of apnea in the scenario rules out eupnea. B: Apnea would be an incomplete assessment as it does not capture the alternating pattern of normal breaths and apnea observed in Biot's respiration. D: Cheyne-Stokes breathing involves a cyclical pattern of gradually increasing and decreasing breathing rates, which is not evident in the scenario described.
