Questions About the Respiratory System Questions
Question 1 of 5
which factors affect on exercise.
Correct Answer: D
Rationale: The correct answer is D, "All of the above." Body temperature (A) is a factor as it affects how efficiently muscles work during exercise. Smoking (B) can negatively impact exercise performance and overall health. Physical exercise (C) is an obvious factor that directly influences exercise outcomes. Therefore, all three factors are interconnected and collectively influence an individual's exercise capacity and performance.
Question 2 of 5
A client has returned to the coronary care unit after having a coronary angiogram. Which assessment data indicate the need for immediate action by the nurse?
Correct Answer: A
Rationale: The correct answer is A: Diminished pedal pulse volume. This indicates potential circulation compromise, which can lead to ischemia or impaired tissue perfusion. Immediate action is required to prevent further complications. B: Heart rate 100 beats/min is within normal range. C: Blood pressure 104/60 mm Hg is slightly low but not critically concerning. D: Capillary refill less than 3 seconds indicates good peripheral perfusion.
Question 3 of 5
The nurse has instructed the client on how to obtain a sputum culture. Which of the statements indicates that the client understood the instruction from the nurse?
Correct Answer: D
Rationale: The correct answer is D because the client demonstrates understanding by acknowledging the need to breathe deeply and cough up the sputum to obtain a sputum culture. This action helps bring up the lower respiratory tract secretions for an accurate culture. Choice A is incorrect because increasing fluids actually helps in sputum production. Choice B is incorrect as mouth care should be done before to prevent contamination. Choice C is incorrect as early morning is the best time due to the accumulation of secretions overnight.
Question 4 of 5
Which of the following substances is activated by passage through the pulmonary circulation?
Correct Answer: D
Rationale: The correct answer is D: Angiotensin 1. When blood passes through the pulmonary circulation, angiotensinogen is converted into angiotensin 1 by the enzyme renin. This activation occurs in the lungs. Bradykinin, serotonin, and noradrenaline are not activated in the pulmonary circulation. Bradykinin is a peptide released during inflammation, serotonin is a neurotransmitter, and noradrenaline is a neurotransmitter and hormone. Therefore, D is the only substance activated by passage through the pulmonary circulation.
Question 5 of 5
A male adult patient hospitalized for treatment of a pulmonary embolism develops respiratory alkalosis. Which clinical findings commonly accompany respiratory alkalosis?
Correct Answer: D
Rationale: The correct answer is D: Lightheadedness or paresthesia. Respiratory alkalosis is caused by hyperventilation, leading to decreased carbon dioxide levels and an increase in pH. This can result in symptoms such as lightheadedness (from decreased cerebral blood flow) and paresthesia (tingling sensations due to changes in calcium ionization). Choices A, B, and C are incorrect as they are not typically associated with respiratory alkalosis. Nausea, vomiting, abdominal pain, and diarrhea are more commonly seen in metabolic alkalosis, while hallucinations and tinnitus are not typical symptoms of respiratory alkalosis.
