Question

the ph of blood must stay *
slightly acid
neutral
slightly basic
moderately acid

which of these is not a symptom of cushing syndrome? *
moon face
buffalo hump
virilization in women
all of these are symptoms of cushing syndrome.

the qrs complex in an electrocardiogram results from *
depolarization of the ventricles
depolarization of the atria
repolarization of the ventricles
repolarization of the atria

Explanation:

1. Normal blood pH ranges from 7.35 to 7.45, which is slightly above the neutral pH of 7, so it is slightly basic.
2. Cushing syndrome, caused by excess cortisol, presents with moon face (facial fat accumulation), buffalo hump (upper back fat deposit), and virilization in women (development of male-like traits) as common symptoms.
3. On an electrocardiogram, the QRS complex corresponds to the electrical activation (depolarization) of the heart's ventricles, which triggers ventricular contraction.

Answer:

1. slightly basic
2. All of these are symptoms of Cushing syndrome.
3. depolarization of the ventricles
