Questions and Answers on Respiratory System Questions
Question 1 of 5
which of the following part of the ear separate middle ear from outer ear
Correct Answer: D
Rationale: The correct answer is D: tympanic membrane because it separates the middle ear from the outer ear. The tympanic membrane, also known as the eardrum, vibrates in response to sound waves and transmits these vibrations to the middle ear. The oval window (A) is a membrane-covered opening in the inner ear that receives vibrations from the stapes bone. The round window (B) is a membrane-covered opening that equalizes pressure within the inner ear. The malleus (C) is a small bone in the middle ear that transmits sound vibrations from the eardrum to the incus. Therefore, the tympanic membrane is the correct answer as it physically separates the middle ear from the outer ear.
Question 2 of 5
The patient with sleep apnea is fitted with a continuous positive airway pressure (CPAP) mask and asks the nurse how this device will help. How should the nurse respond?
Correct Answer: A
Rationale: The correct answer is A because a CPAP mask delivers a constant positive pressure to keep the airway open during sleep, preventing airway collapse and interruptions in breathing. This helps improve oxygenation and reduce the frequency of apnea episodes. Choice B is incorrect as intubation is not required with CPAP. Choice C is incorrect as CPAP does not deliver oxygen, it only provides pressurized air. Choice D is incorrect as CPAP delivers positive pressure, not negative pressure, to support breathing.
Question 3 of 5
Which blood pressure (BP) finding by the nurse indicates that no changes in therapy are needed for a 78-yr-old patient with newly diagnosed hypertension?
Correct Answer: B
Rationale: The correct answer is B (118/76 mm Hg) because it falls within the recommended range for a 78-year-old patient with hypertension. The systolic BP should ideally be below 140 mm Hg and the diastolic BP below 90 mm Hg for this age group. Option A is too low for systolic BP, indicating hypotension. Option C has elevated diastolic BP, suggesting uncontrolled hypertension. Option D has high systolic BP, indicating a need for therapy adjustment. Thus, only option B aligns with the guidelines, making it the correct choice.
Question 4 of 5
Which action should the nurse take first when a client develops epistaxis?
Correct Answer: B
Rationale: The correct action is to apply squeezing pressure to the nostrils for 10 minutes. This helps control the bleeding by promoting clot formation. It is the initial intervention to stop the bleeding before considering other options. Packing the nostril with a balloon (Choice A) may worsen the bleeding. Obtaining silver nitrate (Choice C) for cauterization is not the first-line approach. Instilling vasoconstrictor medication (Choice D) should be considered after applying pressure if bleeding persists.
Question 5 of 5
Which statement is false?
Correct Answer: D
Rationale: The correct answer is D, None of the above, is false. A: Dorsal respiratory group in the upper pons is indeed responsible for inspiration. B: The apneustic centre can inhibit the inspiratory centre, so this statement is true. C: The pneumotaxic centre is responsible for regulating the duration and depth of each breath, not for a prolonged inspiratory gasp interrupted by expiratory efforts. Therefore, choice D is false as all the other statements are accurate.
