b. Convert 1 L to 1000 mL, and then calculate drops needed: $1000\mathrm{m}\mathrm{L}\times <!--\; \times \; -->10\mathrm{d}\mathrm{r}\mathrm{o}\mathrm{p}\mathrm{s}/\mathrm{m}\mathrm{L}=10,000\mathrm{d}\mathrm{r}\mathrm{o}\mathrm{p}\mathrm{s}$. Then divide the total number of drops by the total number of minutes: $10,000\mathrm{d}\mathrm{r}\mathrm{o}\mathrm{p}\mathrm{s}÷(6\mathrm{h}\mathrm{o}\mathrm{u}\mathrm{r}\mathrm{s}\times <!--\; \times \; -->60\mathrm{m}\mathrm{i}\mathrm{n}\mathrm{u}\mathrm{t}\mathrm{e}\mathrm{s}/\mathrm{h}\mathrm{o}\mathrm{u}\mathrm{r})=27.78\mathrm{d}\mathrm{r}\mathrm{o}\mathrm{p}\mathrm{s}/\mathrm{m}\mathrm{i}\mathrm{n}\mathrm{u}\mathrm{t}\mathrm{e}$. Round to 28 drops/minute.

c. Vitamin C is a water-soluble vitamin that is important for the synthesis of collagen and wound healing.

b. Diuretic drugs are prescribed to help the body eliminate excess fluid.

c. Itching, hives, and shortness of breath are common symptoms of an allergic reaction to blood or blood products.

a. $750\text{mL}÷\text{by}8\mathrm{h}\mathrm{o}\mathrm{u}\mathrm{r}\mathrm{s}=93.75\text{mL}/\mathrm{h}\mathrm{o}\mathrm{u}\mathrm{r}$. Round to 94 mL/hour.

d. Vitamin A is a fat-soluble vitamin that can accumulate in the body and potentially cause toxicity.

b. Symptoms of fluid volume deficit include thirst, dry mouth, and tachycardia.

d. Iron should be administered 1 to 2 hours before or after calcium because it may alter its effectiveness.

b. Echinacea is hepatotoxic; therefore, liver function should be monitored.

d. St. John’s wort may interact with many other drugs, including antidepressants.
