question 10 (2 points)
what change occurs as a result of hypoventilation?
partial pressure of carbon dioxide increases.
lungs expel carbon dioxide.
respiratory alkalosis occurs.
none of the above
question 11 (2 points)
a nurse is teaching student nurses about the epidemiology of renal calculi. which statement made by a student nurse indicates the need for further training?
\the lifetime risk of developing nephrolithiasis is around 7% for men in the united states.\

enal calculi develop most commonly in adults aged 20 to 49 years.\
\the risk of developing renal calculi doubles if there is a family history.\

enal calculi can recur, with a chance of 52% recurrence within 10 years.\
question 12 (2 points)
which is the most common condition associated with the formation of renal calculi?
hyperabsorption of calcium and oxalate from the gastrointestinal tract
chronic urinary tract infection
gout
failure of renal tubular reabsorption of cystine

Explanation:

Question 10:

Hypoventilation is a decrease in ventilation, leading to reduced expulsion of carbon - dioxide. This causes an increase in the partial pressure of carbon dioxide in the blood. Lungs expelling carbon dioxide is normal ventilation, and respiratory alkalosis occurs with hyperventilation.

Question 11:

The lifetime risk of developing nephrolithiasis in men in the United States is around 13 - 15%, not 7%. The other statements about the age group, family - history risk, and recurrence rate are correct.

Question 12:

Hyperabsorption of calcium and oxalate from the gastrointestinal tract is a very common cause of renal calculi formation as it increases the concentration of these substances in the urine, promoting crystal formation.

Answer:

Question 10: Partial pressure of carbon dioxide increases.
Question 11: "The lifetime risk of developing nephrolithiasis is around 7% for men in the United States."
Question 12: Hyperabsorption of calcium and oxalate from the gastrointestinal tract
