How does hypoventilation affect the blood's pH?
Less H and HCO3 form, increasing the blood's pH.
More H and HCO3 form, increasing the blood's pH.
Less H and HCO3- form, decreasing the blood's pH.
More H and HCO3 form, decreasing the blood's pH.
The Correct Answer is D
More H and HCO3 form, decreasing the blood's pH.
Rationale: Hypoventilation is a condition where the breathing rate is too slow or shallow, resulting in insufficient removal of carbon dioxide (CO2) from the body. CO2 reacts with water (H2O) to form carbonic acid (H2CO3), which can dissociate into hydrogen ions (H+) and bicarbonate ions (HCO3-). Therefore, when CO2 accumulates in the blood due to hypoventilation, more H2CO3 is formed, which lowers the blood's pH by increasing the concentration of H+ and HCO3-.

Explanation
Spina bifida is a birth defect that occurs when the neural tube, which forms the brain and spinal cord, does not close properly during early fetal development. This can result in an opening in the spine that exposes the spinal cord and nerves, leading to various complications such as paralysis, bladder and bowel problems, hydrocephalus, and learning difficulties. Folic acid is a B vitamin that is essential for the formation of the neural tube and other organs in the embryo. Inadequate folic acid intake before and during pregnancy can increase the risk of spina bifida and other neural tube defects.
Correct Answer is B
Explanation
MRSA stands for methicillin-resistant Staphylococcus aureus, a type of bacteria that is resistant to many antibiotics and can cause serious infections in various parts of the body. MRSA can spread through direct contact with infected people or contaminated objects and can be difficult to treat due to its resistance to treatment. MRSA can progress into blood, bone, lung, or skin infections that may be life-threatening if not treated promptly and appropriately.
