- Question 22 Which of the following is a symptom of asthma? Question 22 options: Shortness of breath Wheezing heard on auscultation Increased work of breathing Tachypnea and decreased O2 satsQuestion 1 When teaching parents what to do if their asthmatic child is in respiratory distress, the nurse would include all of the following EXCEPT: Question 1 options: Seek immediate medical attention if the child is in respiratory distress Do not allow the child to exert themselves Expose the child to cold fresh air to help with breathing Administer Ventolin 2 - 4 puffs every 15 - 20 minutesQuestion 33 Which pccurs during isovolumetric ventricular contraction? O Rapid filling of the ventricles occurs. O No blood enters or leaves the ventricles. The maximum volume of blood is ejected. Ventricular pressure reaches its maximum value of the cardiac cycle. The pressure in the ventricles decreases while the pressure in the atria increases. MacBook Pro O
- I need help with a respiratory question, thank you, I really appreciate it Stroke volume can be calculated using which formula? Group of answer choices End-diastolic volume – end-systolic volume Ejection fraction × heart rate Ejection fraction × end-systolic volume Cardiac output ÷ end-diastolic volumeIf the Mitral Valve failed in a patient, would the blood flow back into the Right Ventricle? Question 6 options: Only if the pulmonary semilunar valves also fail Only if the aortic semilunar valves also fail No, because the flow would be stopped by the bicuspid valve No, because blood can only flow forward, never in the reverse direction.QUESTION 17 Lungs: With age, lung function becomes "less efficient." Which one does not explain why? Lung tissue becomes more "elastic" resulting in less expansion. There is a decrease in "reserve capacity" that affects stamina. There is a decrease in the number of airs sacs for oxygen transport. Muscles in the rib cage become weaker and reduce contraction.
