Oxygen moves from the lungs into the blood via:

A. Waiting 15 minutes after giving the cough syrup is unnecessary. There's typically no reason to delay giving tablets after a liquid medication unless specifically indicated.
B. Giving the cough syrup between the tablets is not an optimal approach, as it could result in potential interactions or interfere with absorption of the medications.
C. Administering the cough syrup first allows the liquid medication to be absorbed more quickly. Afterward, the tablets can be given with water to facilitate swallowing and ensure proper absorption. This order is generally most effective in promoting absorption and preventing interference between the two types of medication.
D. Administering the tablets first may lead to them being coated with the liquid, potentially delaying their absorption and effectiveness.

A. Crackles are discontinuous, short popping sounds that are often heard during inhalation and are typically associated with conditions like pneumonia or pulmonary edema, not asthma.
B. Wheezes are continuous, high-pitched sounds often heard during exhalation and are commonly associated with asthma or other obstructive airway conditions. These sounds are caused by the narrowing of the airways.
C. Stridor is a harsh, high-pitched sound often heard during inhalation and indicates upper airway obstruction, such as in croup or a foreign body in the airway.
D. Rhonchi are low-pitched, gurgling sounds that are often associated with blockages in the larger airways (such as mucus) and are generally heard during both inhalation and exhalation, but they are not typically high-pitched like wheezes.
