A primipara at 20-weeks gestation is scheduled for an ultrasound. In preparing the client for the procedure, the nurse should explain that the primary reason for conducting this diagnostic study is to obtain which information?
A. Chromosomal abnormalities
Chromosomal abnormalities:While an ultrasound can sometimes identify structural abnormalities, it's not the primary tool for detecting chromosomal abnormalities. Genetic testing or procedures like amniocentesis are more specific for this purpose.
B. Sex and size of the infant
Sex and size of the infant:An ultrasound is indeed used to determine the sex of the baby and assess its size and growth.
C. Lecithin-sphingomyelin ratio
Lecithin-sphingomyelin ratio: The lecithin-sphingomyelin ratio is typically assessed in tests related to fetal lung maturity, which is not the primary purpose of a routine ultrasound.
D. Fetal growth and gestational age.
Fetal growth and gestational age:This is one of the primary purposes of a routine ultrasound during pregnancy. It helps evaluate the baby's growth and ensures it aligns with the expected gestational age.

The healthcare provider prescribes magnesium sulfate 6 grams intravenously (IV) to be infused over 20 minutes for client with preterm labor. The IV bag contains magnesium sulfate 20 grams in dextrose 5% in water 500 mL. How many mL/hour should the nurse set the infusion pump?
(Enter numerical value only.)
Full Explanation
- To calculate the infusion rate, use the formula:
(mL of solution / grams of drug) x (grams ordered / minutes to infuse) x 60
- In this case, the formula becomes: (500 mL / 20 g) x (6 g / 20 min) x 60
- Simplify and solve: (25 mL / g) x (0.3 g / min) x 60
- The answer is 450 mL/hour
- The nurse should set the infusion pump at 450 mL/hour
A father watching the admission of his newborn to the nursery notices that eye ointment is placed in the infant's eyes. He asks the nurse what is the purpose of the ointment. The nurse would be correct in stating that the purpose for using the ointment is to
A. dilate the pupil so the red reflex can be visualized
Dilate the pupil so the red reflex can be visualized:This statement is not accurate regarding the purpose of the eye ointment. The eye ointment is not used to dilate the pupil but serves a different purpose.
B. prevent herpes infection.
Prevent herpes infection:While eye ointment can help prevent certain eye infections, it's not specifically administered to prevent herpes infection.
C. prevent eye infections
Prevent eye infections: This is the correct answer. The eye ointment typically contains an antibiotic and is applied to prevent infections, particularly those that could be transmitted during childbirth.
D. clear the infant's vision
Clear the infant's vision:The eye ointment is not used to clear the infant's vision. Its primary purpose is to prevent infections rather than affect vision.

A client who had her first baby three months ago and is breastfeeding her infant tells the nurse that she is currently using the same diaphragm that she used before becoming pregnant. Which information should the nurse provide this client?
A. After ceasing breastfeeding the diaphragm should be resized.
After ceasing breastfeeding, the diaphragm should be resized: Breastfeeding can affect vaginal lubrication and elasticity. It might be advisable to have the diaphragm refitted after childbirth and after breastfeeding stops. However, this choice doesn't directly address the current situation.
B. Use an alternate form of contraception until a new diaphragm is obtained.
Use an alternate form of contraception until a new diaphragm is obtained: This is a reasonable suggestion. Using a diaphragm that was fitted before pregnancy might not offer adequate protection due to potential changes in the cervix's size or shape after childbirth.
C. If no more than 20 pounds was gained during pregnancy, the diaphragm is safe to use.
If no more than 20 pounds were gained during pregnancy, the diaphragm is safe to use: Weight gain during pregnancy can affect the size and shape of the vagina and cervix. However, specifying a particular weight gain as a safety criterion for using the diaphragm isn't entirely accurate.
D. Avoid intercourse during ovulation until the size of the diaphragm has been evaluated
Avoid intercourse during ovulation until the size of the diaphragm has been evaluated: This is a cautious approach. Waiting until the diaphragm size is confirmed by a healthcare professional could be prudent to ensure the correct fit and effectiveness.
