Finely ground mineral (0.5864 g) was dissolved in 25 mL of boiling 4 M HCl and diluted with 175 mL H2O containing two drops of methyl red indicator. The solution was heated to 100C, and 50 mL of warm solution containing 2.0 g (NH4)2C2O4 were slowly added to precipitate CaC2O4. Then 6 M NH3 was added until the indicator changed from red to yellow, showing that the liquid was neutral or slightly basic. After slow cooling for 1 h, the...

Case Study: Opioid-induced Constipation
You work in a pediatric surgical practice. You notice that
children are frequently seen post-discharge for complaints of
abdominal distress and constipation. You suspect opioid-induced
constipation. Your practice has no related practice policies.
Questions: What can you discover about
opioid-induced constipation in your own practice and in general?
Should your practice have a related policy? If not, why not? If so,
what should the policy be?
