Some Bio Questions!! need help!!?

Question

Q1

Daniel, a pilot for a paramedical squad, has recently been stationed to Mexico City for 3 months. Six weeks after his arrival, a routine medical examination shows that his erythrocyte count is elevated, his respiratory rate is above normal, and his hemoglobin O2 saturation level is lower than normal.

What condition is Daniel suffering from?

A very virulent intestinal virus has triggered repeated vomiting and severe diarrhoea in Jessica. After 12 hours of feeling helpless, her frantic flatmates bring her to the health clinic.

(a) Along with rehydration (replacing lost water), what electrolytes must also be replaced in Jessica’s body?

Q2

(b) (b) Shortly after Jessica has been diagnosed and treated, her infant niece starts to exhibit the same signs and symptoms. Three hours later, the baby’s anterior fontanel and eyes appear sunken and she is lethargic with a rapid pulse. Should treatment be sought, or is it safe to wait and see if the baby’s symptoms subside without treatment?

Answer 1

I can answer question 1 easily. In Mexico City we live at 2400m above sea level (like 7000 feet), the guy's body has developed red blood cells as a defense mechanism to survive the lower amount of oxygen available in this city. I know because I live here and know firsthand what it feels like to be on sea level and coming back here and getting hit with the altitude. I've been close to puking a few times because the altitude really hits me hard. If his blood was tested immediately after arriving, it would have still been normal. It makes a red blood cells 10 days to develop. Your body fully adjusts to the altitude in 12 weeks.

It's not a disease what Daniel has, his body is just adjusting to the altitude.

As for Question 2, maybe give her something like Ranitidine to reduce the diahhrea and vomiting along with the rehydration therapy. She needs potassium and sodium for the most part which are the 2 electrolytes that are the biggest problems.

I'd treat that kid as soon as possible. Small children can die like a snap with those kinds of infections. The kid should be taken to an ER immediately.

Answer 2

Q1: Daniel is suffering from high altitude pulmonary edema.

Q2:  a) Mainly primary lytes (Na+, K+, and Cl-), mainly K+ though

        b)Her infant neice is dehydrated (signs = sunken ant. fontanel, sunken eyes, & tachycardia).  Given that the sequelae of Jessica's "virulent intestinal virus" are identical, it would be prudent to treat her infant neice for dehydration and observation.
