A nurse is preparing to infuse 1 liter of 0.9% sodium chloride IV over 8 hr with a tubing set that delivers 15 gtts/mL. The nurse should set the manual IV infusion to deliver how many drops/min? Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.

Answer and Explanation

The Correct Answer is ["31"]

The correct answer is 31 gtts/min. To calculate the infusion rate, the nurse should use the following formula:

Infusion rate (gtts/min) = Volume (mL) x Drop factor (gtts/mL) / Time (min)

Plugging in the given values, we get:

Infusion rate (gtts/min) = 1000 mL x 15 gtts/mL / 480 min

Infusion rate (gtts/min) = 31.25 gtts/min

Rounding to the nearest whole number, we get 31 gtts/min.

Correct Answer is D

Explanation

Choice A: 28 weeks' gestation is too early to screen for group B streptococcus infection. Group B streptococcus (GBS) is a type of bacteria that can cause serious infections in newborns if transmitted from the mother during labor and delivery. The optimal time to screen for GBS is between 35 and 37 weeks' gestation.

Choice B: 32 weeks' gestation is also too early to screen for GBS infection. Screening at this time may not reflect the true colonization status of the mother at the time of delivery, as GBS can be transient or intermittent.

Choice C: 16 weeks' gestation is much too early to screen for GBS infection. Screening at this time has no clinical value, as GBS colonization can change throughout pregnancy.

Choice D: 36 weeks' gestation is the appropriate time to screen for GBS infection. Screening at this time can identify mothers who are colonized with GBS and who need intrapartum antibiotic prophylaxis to prevent neonatal sepsis, pneumonia, and meningitis.

A. 3-2-1-0-3 B. 4-1-1-1-3 C. 4-2-1-3-1 D. 3-1-2-2-3

Correct Answer is B

Explanation

Choice A Reason: This option is incorrect because it underestimates the number of pregnancies (gravida) and overestimates the number of preterm births (preterm). The client has had four pregnancies (twins count as one pregnancy), not three. The client has had one preterm birth (the twins), not two.

Choice B Reason: This option is correct because it accurately reflects the client's obstetric history. GTPAL stands for Gravida, Term, Preterm, Abortions, and Living children. Gravida is the number of pregnancies a woman has had, regardless of outcome. Term is the number of pregnancies that ended at or beyond 37 weeks gestation. Preterm is the number of pregnancies that ended between 20 and 36 weeks gestation. Abortions are the number of pregnancies that ended before 20 weeks gestation, either spontaneously or induced. Living children are the number of children who are alive at present.
The client has had four pregnancies (gravida), one term birth (the son), one preterm birth (the twins), one abortion (the miscarriage), and three living children (the twins and the son).

Choice C Reason: This option is incorrect because it overestimates the number of preterm births (preterm) and underestimates the number of living children (living). The client has had one preterm birth (the twins), not two. The client has three living children (the twins and the son), not one.

Choice D Reason: This option is incorrect because it underestimates the number of pregnancies (gravida) and overestimates the number of abortions (abortions) and preterm births (preterm). The client has had four pregnancies (twins count as one pregnancy), not three. The client has had one abortion (the miscarriage), not two. The client has had one preterm birth (the twins), not two.
