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?
Chromosomal abnormalities
Sex and size of the infant
Lecithin-sphingomyelin ratio
Fetal growth and gestational age.
The Correct Answer is D
A. 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:
An ultrasound is indeed used to determine the sex of the baby and assess its size and growth.
C. 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:
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.

Correct Answer is D
Explanation
A. Cleanse the spinal injection site:
Cleansing the spinal injection site is a routine part of maintaining proper hygiene during and after the administration of spinal anesthesia. However, if the client is experiencing symptoms of a spinal headache, the priority is to prepare for potential interventions by having the necessary equipment ready rather than focusing on the site itself.
B. Apply an abdominal binder:
Applying an abdominal binder is not directly related to addressing a spinal headache. Abdominal binders are typically used for providing support to the abdominal muscles after childbirth or surgery. It wouldn't be the primary intervention for a spinal headache.
C. Insert an indwelling Foley catheter:
Inserting an indwelling Foley catheter is not a direct intervention for addressing a spinal headache. Spinal headaches are related to cerebrospinal fluid leakage and positioning. While managing the patient's overall care is important, it may not be the immediate priority in this context.
D. Place procedure equipment at bedside:
This is the most appropriate action in the context of a postpartal client exhibiting symptoms of a spinal headache. Having the necessary procedure equipment, such as materials for a blood patch, ready at the bedside ensures preparedness for potential interventions by the anesthesiologist.
Correct Answer is ["450"]
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
