Which of the following BEST defines a normal FHR baseline? A) Average FHR rounded to the nearest 5 during a 10-minute window, excluding accelerations and decelerations B) Average FHR rounded to the nearest 10 during a 5-minute window, including all fluctuations C) The lowest FHR sustained for at least 1 minute during a 20-minute period D) The highest FHR observed during a 30-minute tracing, excluding marked variability Answer: A Rationale: The FHR baseline is defined as the average FHR rounded to the nearest 5 beats per minute during a 10-minute window, excluding accelerations, decelerations, and periods of marked variability. At least 2 minutes of identifiable baseline must be present (not necessarily continuous) to establish a baseline. Options B, C, and D describe incorrect measurement parameters. ________________________________________ 2. A patient at 38 weeks gestation has a FHR tracing showing a rate of 105 bpm for 15 minutes. This finding is classified as: A) Normal baseline B) Fetal bradycardia C) Fetal tachycardia D) Minimal variability Answer: B Rationale: Fetal bradycardia is defined as a FHR 110 bpm for ≥10 minutes. The rate of 105 bpm sustained for 15 minutes meets this criteria. A normal baseline is 110-160 bpm. Fetal tachycardia is 160 bpm for ≥10 minutes. Minimal variability refers to amplitude, not rate. ________________________________________ 3. Which of the following is NOT a common cause of fetal bradycardia? A) Cord prolapse B) Maternal fever C) Rapid descent D) Postdates pregnancy Answer: B Rationale: Maternal fever is a cause of fetal tachycardia, not bradycardia. Cord prolapse, rapid descent, and postdates pregnancy are all associated with fetal bradycardia. Other causes include hypotension, head compression, congenital defects, abruption or rupture, tachysystole, hypoglycemia, and lupus (heart block). ________________________________________ 4. A FHR tracing demonstrates a rate of 175 bpm sustained for 12 minutes. Which of the following could be a contributing factor? A) Terbutaline administration B) Magnesium sulfate therapy C) Fetal hypoglycemia D) Fetal sleep cycle Answer: A Rationale: Terbutaline (a betamimetic tocolytic) can cause fetal tachycardia. Fetal tachycardia (160 bpm for ≥10 minutes) can also be caused by fetal anemia, maternal fever/infection, fetal immaturity (preterm), SVT, maternal anxiety, dehydration, hyperthyroid, and hypoxia. Magnesium sulfate is more likely to cause decreased variability and bradycardia. Fetal hypoglycemia is associated with bradycardia, not tachycardia. Sleep cycles cause minimal variability. ________________________________________ 5. When verifying a suspected fetal bradycardia, the nurse should FIRST: A) Prepare for immediate cesarean delivery B) Verify it is not the maternal heart rate C) Administer oxygen at 10L/min D) Increase the IV fluid rate Answer: B Rationale: The first step when suspecting fetal bradycardia is to verify it is not the maternal heart rate being detected. The nurse should palpate the maternal radial pulse simultaneously while auscultating the FHR to differentiate. Following verification, interventions such as position change, vaginal exam to rule out cord prolapse, resuscitation, and preparation for expedited delivery may be indicated. ________________________________________ 6. Fetal tachycardia is defined as: A) FHR 160 bpm for ≥5 minutes B) FHR 160 bpm for ≥10 minutes C) FHR 180 bpm for ≥15 minutes D) FHR 200 bpm for ≥5 minutes Answer: B Rationale: Fetal tachycardia is defined as a FHR 160 beats per minute sustained for ≥10 minutes. The baseline must be established using a 10-minute window, and the tachycardia must persist for at least 10 minutes to be classified as such. Options A, C, and D incorrectly describe the duration and rate parameters. ________________________________________ 7. Which maternal condition is most likely to cause fetal bradycardia secondary to congenital heart block? A) Diabetes mellitus B) Systemic lupus erythematosus (SLE) C) Gestational hypertension D) Hyperthyroidism Answer: B Rationale: Systemic lupus erythematosus (SLE) can cause congenital 3rd-degree heart block in the fetus. The autoimmune inflammatory response leads to overgrowth of collagen in the heart muscle, damaging the fetal conduction system. This is usually diagnosed in the second trimester. Diabetes, hypertension, and hyperthyroidism are not directly associated with fetal heart block. ________________________________________ 8. A FHR tracing shows a baseline of 155 bpm with periods of rate dropping to 80 bpm during contractions. The nurse should: A) Document this as a normal tracing B) Assess for maternal fever C) Differentiate between bradycardia and decelerations D) Prepare for immediate delivery Answer: C Rationale: The nurse must differentiate between true fetal bradycardia (sustained low rate for ≥10 minutes) and recurrent decelerations. Bradycardia is a baseline change, while decelerations are transient drops that return to baseline. The rate dropping to 80 bpm during contractions suggests decelerations, which require evaluation of pattern type (early, variable, late). Documentation and intervention would depend on the classification of the decelerations and the overall category of the tracing. ________________________________________ 9. A preterm fetus at 33 weeks gestation is likely to exhibit which baseline characteristic compared to a term fetus? A) Lower baseline FHR B) Higher baseline FHR C) More moderate variability D) Fewer accelerations Answer: B Rationale: Preterm fetuses typically have a higher baseline FHR due to immaturity of the parasympathetic nervous system and decreased vagal tone. They also tend to have less variability and fewer accelerations. The immature central nervous system is not fully developed, resulting in these differences compared to term fetuses.
