Questions and Answers on Respiratory System Questions
Question 1 of 5
In medical term shortness of breathing known as
Correct Answer: C
Rationale: The correct answer is C: Both A and B. "SOB" is the abbreviation for shortness of breath, while "dyspnea" is the medical term for difficulty breathing. Both terms are used interchangeably to describe the sensation of breathing difficulty. Choosing C is correct because it encompasses both terms that are synonymous with the medical condition. Option D is incorrect because there are appropriate terms for shortness of breathing, which are provided in options A and B. Option A is incorrect because it only provides the abbreviation for the term without the actual medical term. Option B is incorrect because it only provides one of the terms used to describe shortness of breathing, while the correct answer includes both terms.
Question 2 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 3 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 4 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.
Question 5 of 5
The organ of the respiratory system that closes when food is being swallowed is the:
Correct Answer: C
Rationale: The correct answer is C: larynx. The larynx houses the vocal cords and serves as a passageway for air between the pharynx and trachea. During swallowing, the larynx closes to prevent food and liquids from entering the airway, directing them towards the esophagus instead. The nose (A) is not directly involved in swallowing. The pharynx (B) is a shared pathway for both air and food, but it does not actively close during swallowing. The trachea (D) is responsible for transporting air to and from the lungs and does not play a role in swallowing.
