Questions on the Respiratory System Questions
Question 1 of 5
Which of the following are not present prior to birth?
Correct Answer: D
Rationale: The correct answer is D: Alveoli are expanded. Prior to birth, the alveoli in the lungs are collapsed, and they begin to expand and develop after birth when the baby starts breathing air. A: Pulmonary arterial resistance is high due to blood flow bypassing the lungs. B: Pulmonary vessels are collapsed to prevent blood flow in the fetal lungs. C: The rib cage is compressed in the womb due to the limited space, but it expands after birth to allow for lung expansion.
Question 2 of 5
cochlea's have how many fluid filled chamber?
Correct Answer: C
Rationale: The cochlea has 3 fluid-filled chambers: the scala vestibuli, scala media, and scala tympani. These chambers are essential for hearing as they contain different fluids (perilymph and endolymph) that help transmit sound vibrations. Choice A (1 chamber) is incorrect as the cochlea has multiple distinct chambers. Choice B (2 chambers) is incorrect as it does not accurately reflect the anatomical structure of the cochlea. Choice D (4 chambers) is incorrect as the cochlea typically consists of 3 chambers, not 4. Therefore, the correct answer is C (3 chambers) based on the accurate anatomical structure of the cochlea.
Question 3 of 5
during rest state normal breathing called
Correct Answer: C
Rationale: The correct answer is C: Diaphragmatic breathing. During rest, normal breathing involves the diaphragm contracting and moving downward to draw air into the lungs. This type of breathing is known as diaphragmatic breathing. Choice A (Breathing) is too broad and does not specify the involvement of the diaphragm. Choice B (Diaphragmatic) does not fully describe the process of breathing during rest. Choice D (Non) is incorrect as it does not provide any information related to the breathing process during rest state. Therefore, C is the most accurate choice as it specifically identifies the type of breathing that occurs during rest.
Question 4 of 5
The nurse is caring for a patient with advanced emphysema. Which sign isn't manifestations of this disorder?
Correct Answer: D
Rationale: The correct answer is D: Wheezing. Emphysema is characterized by destruction of lung tissue, leading to air trapping and decreased airflow. Wheezing is typically associated with asthma or bronchitis, not emphysema. A: Productive cough is common in emphysema due to increased mucus production. B: Dyspnea (shortness of breath) is a hallmark symptom of emphysema due to impaired gas exchange. C: Barrel chest is a physical finding in emphysema caused by hyperinflation of the lungs.
Question 5 of 5
Which information from a client helps the nurse confirm the previous diagnosis of chronic stable angina?
Correct Answer: D
Rationale: The correct answer is D because chronic stable angina is characterized by chest pain or discomfort that is triggered by physical exertion or emotional stress and relieved by rest or medication. Therefore, the fact that the pain goes away after stopping jogging aligns with the typical pattern of chronic stable angina. A: The pain waking the client up at night is more indicative of unstable angina or a heart attack. B: The level of pain on a scale does not provide conclusive evidence of chronic stable angina. C: Pain worsening over time may suggest unstable angina or a heart attack rather than chronic stable angina.
