What is the rationale for the order of supplemental oxygen 10 L/min via nasal cannula? Select the best answer.
To prevent hypoxia and tissue damage due to pneumonia.
To lower the blood pressure and reduce the workload of the heart.
To increase the oxygen saturation and improve the respiratory function.
To dilate the bronchioles and decrease the inflammation of the lungs.
The Correct Answer is A
Choice A rationale:
Supplemental oxygen is given to the patient to prevent hypoxia and tissue damage due to pneumonia. Pneumonia is an infection that inflames the air sacs in one or both lungs, which may fill with fluid or pus, causing cough with phlegm or pus, fever, chills, and difficulty breathing. Hypoxia occurs when the body or a region of the body is deprived of adequate oxygen supply at the tissue level. It can cause serious damage to your heart, brain, and other organs. Hence, supplemental oxygen is administered to ensure that the patient’s tissues receive adequate oxygen.
Choice B rationale:
While supplemental oxygen can indirectly help lower blood pressure by improving oxygen supply and reducing strain on the heart, it is not primarily used for this purpose. Enalapril, which the patient is already taking, is an angiotensin-converting enzyme (ACE) inhibitor that is commonly used to lower blood pressure and reduce the workload of the heart.
Choice C rationale:
Supplemental oxygen does increase the oxygen saturation and improve respiratory function. However, this is a more general rationale for providing supplemental oxygen and not specific to this patient’s condition of pneumonia.
Choice D rationale:
Supplemental oxygen does not directly dilate the bronchioles or decrease inflammation in the lungs. Medications such as bronchodilators and corticosteroids are typically used for these purposes. In this case, supplemental oxygen is being used to prevent hypoxia and tissue damage due to pneumonia.

Correct Answer is D
Explanation
The correct answer is d. hypovolemic.
Choice A reason: This is not a good choice. Septic shock is a type of distributive shock that occurs when an infection causes a systemic inflammatory response that leads to vasodilation, hypotension, and organ dysfunction. Septic shock is not the most common type of shock in children, although it can be a serious and life-threatening condition.
Choice B reason: This is not a good choice. Anaphylactic shock is a type of distributive shock that occurs when an allergic reaction causes a severe and rapid hypersensitivity response that leads to bronchoconstriction, angioedema, and hypotension. Anaphylactic shock is not the most common type of shock in children, although it can be a medical emergency that requires immediate treatment.
Choice C reason: This is not a good choice. Distributive shock is a broad category of shock that occurs when there is a loss of vascular tone and blood volume distribution that leads to hypoperfusion and tissue hypoxia. Distributive shock can be caused by various factors, such as sepsis, anaphylaxis, neurogenic injury, or adrenal insufficiency. Distributive shock is not the most common type of shock in children, although it can be a complex and challenging condition to manage.
Choice D reason: This is the correct choice. Hypovolemic shock is the most common type of shock in children. Hypovolemic shock occurs when there is a loss of blood or fluid volume that leads to decreased preload, cardiac output, and blood pressure. Hypovolemic shock can be caused by various factors, such as hemorrhage, dehydration, vomiting, diarrhea, or burns. Hypovolemic shock can be a life-threatening condition that requires prompt fluid resuscitation and correction of the underlying cause.
Correct Answer is C
Explanation
Choice A rationale:
A bottle is generally much better than using a pacifier. This statement is not accurate. Prolonged bottle use, especially with sugary liquids like milk, can have adverse effects on a child's dental health. It can lead to an increased risk of cavities, similar to prolonged pacifier use.
Choice B rationale:
The bottle will assist in preventing thumb sucking. This statement is incorrect. While a bottle may provide comfort to a child, it does not prevent thumb sucking. Thumb sucking is a separate behavior that may also have dental implications if it persists beyond a certain age.
Choice C rationale:
Prolonged bottle use can increase the risk for cavities. This response is correct. Prolonged bottle use, especially with milk or sugary beverages, can expose the child's teeth to prolonged contact with sugars, increasing the risk of cavities. It's important for the nurse to educate the mother about the potential dental risks associated with extended bottle use.
Choice D rationale:
Using milk rather than juice helps to avoid tooth decay. While milk is generally considered a healthier choice than juice, the key issue in this scenario is the prolonged use of the bottle, regardless of its content. Prolonged bottle use with any liquid, including milk, can still increase the risk of cavities.
