Multiple Choice Questions and Answers on Respiratory System Questions
Question 1 of 5
Carina is the point where ...... divided
Correct Answer: A
Rationale: The correct answer is A: Trachea. Carina is the point where the trachea is divided into the left and right primary bronchi. This anatomical landmark is located at the lower end of the trachea where it bifurcates into the bronchi. The other choices, B: bronchi and C: larynx, are incorrect because the trachea is the structure that is divided at the carina, not the bronchi or larynx. Choice D: none of them is also incorrect because the trachea is indeed divided at the carina. Therefore, the correct answer is A as it accurately describes the anatomical location where the trachea divides.
Question 2 of 5
The patient with asthma is prescribed a leukotriene modifier drug, montelukast (Singulair). Which statement describes an advantage of this medication?
Correct Answer: B
Rationale: The correct answer is B because montelukast is a leukotriene modifier that works by reducing inflammation and promoting bronchodilation in asthma patients. This helps in managing asthma symptoms and improving lung function. A is incorrect because montelukast can cause mild GI side effects such as nausea and diarrhea. C is incorrect because while montelukast helps in controlling asthma symptoms, it does not provide immediate relief during acute episodes. D is incorrect because montelukast is typically used as an add-on therapy and not as a replacement for all other asthma medications.
Question 3 of 5
Which action should the nurse in the hypertension clinic take to obtain an accurate baseline blood pressure (BP) for a new client?
Correct Answer: B
Rationale: The correct answer is B because having the client sit in a chair with feet flat on the floor is the recommended position for accurate baseline BP measurement. This position ensures proper alignment of the heart and the cuff, reducing errors caused by arm positioning. Choice A is incorrect as deflating the cuff at a rate of 30 mm Hg per second is not related to obtaining an accurate baseline BP measurement. Choice C is incorrect as measuring BP in the supine position can lead to inaccurate readings due to changes in blood flow dynamics. Choice D is incorrect as obtaining two BP readings in the dominant arm and averaging the results may not provide an accurate baseline BP measurement due to variations in BP readings between arms.
Question 4 of 5
A client who has chronic heart failure tells the nurse 'I was fine when I went to bed but I woke up in the middle of the night feeling like I was suffocating!' How should the nurse document this finding?
Correct Answer: C
Rationale: The correct answer is C: Paroxysmal nocturnal dyspnea. This finding describes the sudden onset of severe shortness of breath at night, commonly seen in patients with chronic heart failure due to fluid redistribution when lying down. Orthopnea (A) is difficulty breathing when lying flat, not specifically at night. Pulsus alternans (B) is a regular rhythm with alternating strong and weak pulses, not related to this patient's symptom. Acute bilateral pleural effusion (D) is a buildup of fluid in the lungs, not a sudden onset symptom like in this case.
