A nurse is preparing to administer Ringer's lactate by continuous IV infusion at 120 mL/hr. The drop factor of the manual IV tubing is 10 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["20"]
- To find out how many gtt/min to set for a manual IV infusion, we need to use this formula: gtt/min = (mL/hr x drop factor) / 60
- In this formula, mL/hr is the rate of infusion in milliliters per hour, drop factor is the number of drops per milliliter for a specific IV tubing, and 60 is the number of minutes in an hour.
- We plug in the given values into this formula: gtt/min = (120 mL/hr x 10 gtt/mL) / 60
- We simplify and solve this equation: gtt/min = (1200 gtt/hr) / 60
- We divide both sides by 60: gtt/min = 20 gtt/hr
- We round off to the nearest whole number: gtt/min = **20**
- We add a leading zero if needed: gtt/min = **20**
- We do not add a trailing zero: gtt/min = **20**

Correct Answer is B
Explanation
Choice A: Danazol is not the correct answer because it is a drug that can be used to treat fibrocystic breast disease. Danazol is a synthetic hormone that reduces the production of estrogen and progesterone, which are involved in the development of breast cysts.
Choice B: Penicillin is the correct answer because it is a drug that has no effect on fibrocystic breast disease. Penicillin is an antibiotic that is used to treat bacterial infections, such as strep throat or syphilis. It has no role in the management of fibrocystic breast disease.
Choice C: Bromocriptine is not the correct answer because it is a drug that can be used to treat fibrocystic breast disease. Bromocriptine is a dopamine agonist that inhibits the secretion of prolactin, which is a hormone that stimulates breast tissue growth and milk production.
Choice D: Tamoxifen is not the correct answer because it is a drug that can be used to treat fibrocystic breast disease. Tamoxifen is an anti-estrogen that blocks the action of estrogen on breast cells, which can reduce the size and number of breast cysts.

Correct Answer is D
Explanation
Choice A: Breast milk is not the correct answer because it is not a route of transmission for syphilis. Syphilis is caused by a bacterium called Treponema pallidum, which cannot survive in breast milk. However, breastfeeding mothers with syphilis should be treated with antibiotics to prevent other complications.
Choice B: The birth canal is not the correct answer because it is not a route of transmission for syphilis. Syphilis can be transmitted through sexual contact, but not through vaginal delivery. However, pregnant women with syphilis should be screened and treated before delivery to prevent congenital syphilis in their newborns.
Choice C: Amniotic fluid is not the correct answer because it is not a route of transmission for syphilis. Syphilis cannot cross the amniotic membrane, which protects the fetus from infections in the uterus. However, pregnant women with syphilis should be monitored for signs of fetal distress or premature rupture of membranes.
Choice D: Placenta is the correct answer because it is a route of transmission for syphilis. Syphilis can cross the placenta, which connects the mother and the fetus through blood vessels. This can result in congenital syphilis, which can cause serious problems such as stillbirth, miscarriage, low birth weight, deformities, or neurological damage in newborns.
