An adult patient presents with a complaint of a cough that has lasted for two weeks. The patient has a rapid, shallow respiratory rate of 34 breaths per minute. Auscultation of the lungs reveals bilateral rhonchi in the upper lobes and diminished breath sounds in the bilateral lower lobes. The patient is diagnosed with bilateral pneumonia and respiratory alkalosis. What is the expected arterial blood gas laboratory value for this patient?
pH 7.5 and PaCO2 32 mm Hg
pH 6.5 and PaCO2 40 mm Hg
pH 6.5 and PaCO2 32 mm Hg
pH 7.5 and PaCO2 40 mm Hg
The Correct Answer is A
Respiratory alkalosis is a condition where the blood's pH is elevated due to excessive removal of CO2 from the body. This can occur when the breathing rate is too fast or deep, such as in response to hypoxia, anxiety, fever, or lung disease. When CO2 is removed from the blood, less H2CO3 is formed, which raises the blood's pH by decreasing the concentration of H+ and HCO3- . A normal blood pH is between 7.35 and 7.45, and a normal partial pressure of arterial carbon dioxide (PaCO2) is between 35- and 45 mm Hg. Therefore, a patient with respiratory alkalosis would have a higher-than-normal pH and a lower-than-normal PaCO2.

Correct Answer is B
Explanation
Oliguria is a condition where the urine output is less than normal, usually less than 500 mL per day in adults. Oliguria can be a sign of dehydration, which occurs when the body loses more water than it takes in. Dehydration can cause various symptoms such as thirst, dry mouth, headache, dizziness, fatigue, and confusion.
Dehydration can also affect kidney function and lead to electrolyte imbalances and acid-base disorders.
Correct Answer is B
Explanation
Naïve T cells are a type of white blood cell that has not encountered a specific antigen before and are ready to respond to new infections. As people age, the number of naïve T cells decreases due to the shrinking of the thymus gland, which produces and matures T cells. This reduces the ability of the immune system to recognize and fight new pathogens and lowers the effectiveness of vaccines.
