NCLEX RN Questions on Respiratory System Questions
Question 1 of 5
which of the following is a chronic respiratory disorder caused by smoking?
Correct Answer: B
Rationale: Emphysema is the correct answer because it is a chronic respiratory disorder specifically caused by smoking. Smoking damages the air sacs in the lungs, leading to shortness of breath and difficulty breathing. Asthma is a separate condition involving airway inflammation. Respiratory alkalosis and acidosis refer to imbalances in blood pH levels, not directly caused by smoking.
Question 2 of 5
The nurse is caring for a first-day postoperative thoracotomy patient. The nurse assesses that the level of drainage has not increased over the last 3 hours. After assessing the patient’s respiratory status, what should the nurse do next?
Correct Answer: B
Rationale: The correct answer is B: Check the tubing for kinks. This is the best next step because stagnant drainage could be caused by a kink in the tubing, obstructing proper drainage. By checking for kinks, the nurse ensures proper functioning of the drainage system, preventing potential complications such as fluid buildup or infection. Raising the system above the patient's heart (A) may not address the underlying issue of kinked tubing. Repositioning the patient (C) may not be necessary if the drainage is not related to patient positioning. Notifying the physician (D) should be done after checking the tubing for kinks, as it is important to troubleshoot and address the issue promptly.
Question 3 of 5
The nurse on the intermediate care unit received a change-of-shift report on four patients with hypertension. Which patient should the nurse assess first?
Correct Answer: A
Rationale: The correct answer is A. The nurse should assess the 48-yr-old with a blood pressure of 160/92 mm Hg who reports chest pain first because chest pain can be a sign of a cardiac issue, which could be life-threatening. Assessing this patient first is crucial to rule out any acute cardiac events. Leg cramping (choice B) is a common symptom in hypertensive patients but is not as urgent as chest pain. High creatinine levels (choice C) may indicate kidney issues but do not require immediate assessment compared to chest pain. Microalbuminuria (choice D) is a sign of kidney damage in hypertension but does not pose an immediate threat like chest pain.
Question 4 of 5
Which assessment findings aren't consistent with a client diagnosis of right-sided heart failure?
Correct Answer: A
Rationale: The correct answer is A because collapsed neck veins are not consistent with right-sided heart failure. In right-sided heart failure, venous congestion leads to jugular venous distention, not collapse. Distended abdomen (choice B) occurs due to fluid accumulation in the abdomen, a common finding in right-sided heart failure. Dependent edema (choice C) results from fluid retention in the lower extremities, also seen in right-sided heart failure. Decreased appetite (choice D) can be present due to abdominal discomfort from fluid accumulation. Therefore, the presence of collapsed neck veins is the only assessment finding that is not indicative of right-sided heart failure.
Question 5 of 5
O2 dissociation curve shift to R) by all of the following except
Correct Answer: D
Rationale: The correct answer is D: Carbon monoxide. Carbon monoxide does not shift the O2 dissociation curve to the right (R) because it binds to hemoglobin with a higher affinity than oxygen, causing a leftward shift (L). Increased [H+], pCO2, and temperature all shift the curve to the right by decreasing hemoglobin's affinity for oxygen.
