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: Sporadic vaginal bleeding accompanied by chronic pelvic pain is not the correct answer because it is not a symptom of cystocele or rectocele. This symptom may indicate other conditions such as endometriosis, fibroids, or cervical cancer.
Choice B: Menstrual irregularities and hirsutism on the chin are not the correct answers because they are not symptoms of cystocele or rectocele. These symptoms may indicate other conditions such as polycystic ovary syndrome (PCOS), thyroid disorder, or menopause.
Choice C: Heavy leukorrhea with vulvar pruritus is not the correct answer because it is not a symptom of cystocele or rectocele. This symptom may indicate other conditions such as bacterial vaginosis, yeast infection, or sexually transmitted infection (STI).
Choice D: Stress incontinence with a feeling of low abdominal pressure is the correct answer because it is a symptom of cystocele or rectocele. Stress incontinence is a condition that causes leakage of urine when there is increased pressure on the bladder, such as during coughing, sneezing, laughing, or lifting. Cystocele or rectocele can cause stress incontinence by weakening the pelvic floor muscles and connective tissue that supports the bladder and urethra. The feeling of low abdominal pressure is also a symptom of cystocele or rectocele, as it indicates that the bladder or rectum is protruding into the vagina.
