Your neighbors are purchasing bottles of water for a backyard barbecue. They are expecting 90 guests and want to provide an average of 2 bottles of water per guest. The bottles of water are sold in packages of eighteen. Set up the problem below and calculate the number of eighteen-packs of bottles of water they will need. Place your conversion factors in order such that "guests" cancels first. 90 guests \( \times \) packages

Jill wrote the number 40 . If her rule is add 7 , what is the fourth number in Jill's pattern? How can you check your answer?

A nurse is preparing to administer tobramycin \( 4 \mathrm{mg} / \mathrm{kg} / \) day IM divided in three equal doses to a client who weighs 60 kg . Available is tobramycin \( 40 \mathrm{mg} / \mathrm{mL} \). How many mL should the nurse administer per dose? (Round the answer to the whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A nurse is preparing to administer morphine 4 mg IM. Available is morphine injection \( 10 \mathrm{mg} / \mathrm{mL} \). How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

(t) \( \frac{7}{8}-\frac{3}{4}+\frac{5}{16} \)

A nurse is preparing to administer cefazolin 1 g IM . The nurse reconstitutes a 1 g vial of cefazolin with sterile water to yield a final concentration of \( 330 \mathrm{mg} / \mathrm{mL} \).
