Q

When considering the use of fetal movement counting for a particular patient, it is important to know that:

A) fetuses move constantly, so the counting can be done at any time.
B) fetal movement is strongest at 29–38 weeks.
C) most women do not feel the fetus move before 24 weeks.
D) there is only one way to perform fetal movement counts.

A

B) fetal movement is strongest at 29–38 weeks.

Fetal movement counting is a safe, simple, no-cost, noninvasive fetal assessment technique. Research has demonstrated that fetal activity is a good predictor of well-being. A dramatic decrease or cessation of such movement is cause for concern.

Q

On physical examination at an initial prenatal visit of a 25-year-old woman who is at 14 weeks’ gestation, you feel a 1-cm, mobile, well-defined, nontender mass in the upper, outer quadrant of her right breast. Your plan is to:

A) explain that this is normal with the hormonal changes of pregnancy.
B) advise the patient that you will watch this mass at each visit to assess for any change.
C) schedule a mammogram to be done in the third trimester.
D) refer the patient for further evaluation with biopsy.

A

B) advise the patient that you will watch this mass at each visit to assess for any change.

This well-defined, nontender mass has benign characteristics, and watching it would be an acceptable approach. A malignant breast mass is usually nontender, firm, irregularly shaped, and fixed to underlying tissue.

Q

The effect of pregnancy on the cardiovascular system is most clearly seen in:

A) lower diastolic blood pressure in the third trimester.
B) a 10% cardiac volume increase that peaks in midpregnancy.
C) a resting pulse increase of 10–15 beats in the first trimester.
D) a slight decrease in cardiac output in the second trimester.

A

B) a 10% cardiac volume increase that peaks in midpregnancy.

Cardiac volume increases by approximately 10% and peaks at about 20 weeks, and resting pulse increases by 10–15 beats per minute, with the peak occurring at 28 weeks.

Q

Pregnant for the third time, the patient has an obstetric history that indicates two miscarriages at 16 and 18 weeks, respectively, and one twin birth at 36 weeks. One twin died, but the other is alive and well. The four-digit descriptor of this history is:

A) 121
B) 221
C) 2021
D) 2201

A

A) 121

The patient has not had any term pregnancies, which accounts for the first number, 0. She had a preterm delivery at 36 weeks of twins, which accounts for the second number; even though these were twins, they still count as one number—thus, the 1. The patient had two miscarriages at less than 20 weeks, which accounts for the third number, a 2. The fourth number is the total number of living children. One of the patient’s twins died; therefore, she has only one living child.

C) evaluating the size of the uterus.
D) evaluating adequacy of fetal growth.

A

B) finding the direction in which the fetus is lying.

Serologic testing measuring MSAFP, estriol, and hCG is called a triple screen; with the addition of inhibin A, this becomes a quad screen.

B) progesterone’s effect on the vessel walls.
C) increased cardiac output.
D) pooling of plasma in the tissues.

Nausea and vomiting of pregnancy are most common in the first trimester. It is recommended that patients eat small, frequent meals, with no restriction on the kind of food or how often. Education includes discontinuing prenatal vitamins with iron until nausea and vomiting have resolved, but continuing folic acid. Other recommendations may include consuming raspberry tea, peppermint tea, carbonated beverages, or hard candy; using acupressure, including sea bands for wrists; taking ginger 1 g per day in divided doses, pyridoxine (vitamin B6) 25 mg BID or TID orally, doxylamine 12.5 mg BID or QID with pyridoxine orally, metoclopramide 5 to 10 mg g q6–8h orally, or promethazine 25 mg q4h per rectal suppository.

Normal findings on speculum and pelvic examination of a pregnant person include:

A) bluish color of the cervix.
B) pale vaginal mucosa.

Q

A patient’s (G2 P1001) initial visit reveals a healthy pregnant patient. The urinalysis and culture and sensitivity (C&S) report indicates a colony count of greater than 100,000 organisms per milliliter. You would:

A) refer the patient to a urologist to evaluate for underlying renal disease.
B) encourage fluids and repeat C&S in 2 weeks.
C) initiate treatment with antibiotics.
D) advise the patient to contact you in case of any UTI symptoms.

A

C) initiate treatment with antibiotics.

A diagnosis of a UTI can be made by finding 100,000 colonies of pathogenic bacteria in a urinary culture. Treatment with appropriate antibiotics is necessary. Untreated asymptomatic bacteriuria may lead to pyelonephritis, which may lead to serious complications for both mother and baby.

46
Q

The etiology of polyhydramnios is associated with:

A) maternal overhydration.
B) fetal anomalies of the GI tract.
C) fetal anomalies of the cardiovascular system.

Q

A 32-year-old patient (G1 P1001), during a discussion of infant care and breastfeeding, says, “My first baby did not like the breast, then I did not have enough milk, so I stopped breastfeeding after 2 weeks.” What is your response to her statement?

A) Tell the patient that she probably misinterpreted what was going on and should not have stopped nursing.
B) Delve further into what occurred and how the patient came to the conclusions that led her to stop breastfeeding.
C) Let the patient know that she probably was not drinking enough fluids, so she did not have enough milk to feed the baby.
