A developing fetus gets oxygen from its mothers blood. Fetal capillaries run through pools of maternal blood in an organ called the placenta. As fetal blood runs through these capillaries, it exchanges substances with the maternal blood around the capillary. The hemoglobin made by a fetus is different than that made after birth. Fetal hemoglobin binds oxygen more strongly at low oxygen levels than normal hemoglobin. How would fetal hemoglobins somewhat higher affinity for oxygen benefit the fetus?
The respiratory system_______. a. provides body tissues with oxygen b. provides body tissues with oxygen and carbon dioxide c. establishes how many breaths are taken per minute d. provides the body with carbon dioxide
Which of the following lamellar body counts indicates mature fetal lungs? 1) 15,000/uL 2) 30,000/uL 3) 45,000/uL 4) 60,000/uL
When a baby is born prematurely, its lung cells are often not differentiated. What can physicians do to accelerate lung development?
You are providing care to a 14 year old male teenager that was informed by the doctor of having restrictive pulmonary disease. A pulmonary function test was performed and also a TB test was done to evaluate his loss of in respiratory function and it was determined that he had reduced lung expansion. The child asks you several questions because he wants to learn much more about the ventilation process of his respiratory system. He asked the following questions because he noticed that you are a knowledgeable nurse. Which muscles typically allow him to ventilate at rest, and how much air is ventilated?
Explain why the first breath of a healthy neonate is more difficult than subsequent breaths and why premature infants often require respiratory assistance (a mechanical ventilator) to keep their lungsinflated. How else is this condition treated?
Describe fetal breathing movements and their purpose
When do fetal breathing movements begin?a. around week 20b. around week 37c. around week 16d. after birth

The child asks you several questions because he wants to learn much more about the ventilation process of his respiratory system. He asked the following questions because he noticed that you are a knowledgeable nurse. He wants to know why the doctor had him take a deep breath and then force as much air out as possible into a round instrument with a gauge? The doctor wrote down two different measurements, what was being measured, the child asked?
While the family is manually ventilating a 3-year-old boy with a tracheostomy tube, the child’s heart rate begins to drop, and he becomes cyanotic. During auscultation, breath sounds are significantly diminished bilaterally. Which action should the family member take after suctioning the tracheostomy tube produces no improvement?
As the diaphragm contracts, the rib cage expands and the lungs fill with air. This is an inhalation true or false
What causes wheeze in a patient suffering from an acute exacerbation of asthma? Question 19 options: Alveolar air trapping due to collapse of distal airways Presence of mucus plugs that occlude proximal bronchioles High velocity air travelling through narrowed airways Inadequate oxygenation of the blood and associated hypoxemia
