HESI Focus on Maternity Exam
1. A charge nurse is teaching a group of staff nurses about fetal monitoring during labor. Which of the following findings should the charge nurse instruct the staff members to report to the provider?
- A. Contraction durations of 95 to 100 seconds
- B. Contraction frequency of 2 to 3 minutes apart
- C. Absent early deceleration of fetal heart rate
- D. Fetal heart rate is 140/min
Correct answer: A
Rationale: The correct answer is A. Contraction durations of 95 to 100 seconds are prolonged, indicating uterine hyperstimulation, which can lead to fetal distress and requires immediate intervention. Reporting this finding to the provider is crucial to ensure timely management and prevent adverse outcomes. Choice B, contraction frequency of 2 to 3 minutes apart, is within the normal range and does not raise immediate concerns. Choice C, absent early deceleration of fetal heart rate, is a reassuring finding suggesting fetal well-being. Choice D, a fetal heart rate of 140/min, is also normal for a fetus and does not typically require immediate reporting unless it deviates significantly from the baseline or is accompanied by other concerning signs.
2. A healthcare professional is caring for a client who is 14 weeks of gestation. At which of the following locations should the healthcare professional place the Doppler device when assessing the fetal heart rate?
- A. Midline 2 to 3 cm (0.8 to 1.2 in) above the symphysis pubis
- B. Left Upper Abdomen
- C. Two fingerbreadths above the umbilicus
- D. Lateral at the Xiphoid Process
Correct answer: A
Rationale: At 14 weeks of gestation, the uterus is still relatively low in the abdomen. Placing the Doppler midline 2 to 3 cm above the symphysis pubis is appropriate for assessing the fetal heart rate. This location allows for better detection of the fetal heart tones as the uterus is at a lower position during this stage of pregnancy. Placing the Doppler on the left upper abdomen would not be ideal at 14 weeks gestation as the uterus is not yet at that level. Placing it two fingerbreadths above the umbilicus or lateral at the xiphoid process would also not be accurate for locating the fetal heart rate at this stage of gestation.
3. A newborn is being assessed following a forceps-assisted birth. Which of the following clinical manifestations should the nurse identify as a complication of the birth method?
- A. Hypoglycemia
- B. Polycythemia
- C. Facial Palsy
- D. Bronchopulmonary dysplasia
Correct answer: C
Rationale: Facial palsy is a known complication of forceps-assisted birth. During forceps delivery, pressure applied to the facial nerve can result in facial palsy. The newborn may present with weakness or paralysis of the facial muscles on one side. Hypoglycemia (Choice A) is not directly related to forceps-assisted birth. Polycythemia (Choice B) is a condition characterized by an increased number of red blood cells and is not typically associated with forceps delivery. Bronchopulmonary dysplasia (Choice D) is a lung condition that primarily affects premature infants who require mechanical ventilation and prolonged oxygen therapy, not a direct outcome of forceps-assisted birth.
4. Which synthetic hormone is used to prevent miscarriages and can cause masculinization of the fetus?
- A. Testosterone
- B. Estrogen
- C. Progestin
- D. Oxytocin
Correct answer: C
Rationale: Progestin is the synthetic hormone used to prevent miscarriages. While it is beneficial in maintaining pregnancy, in some cases, it can lead to masculinization of the fetus. Testosterone (Choice A) and estrogen (Choice B) are not typically used to prevent miscarriages and do not cause masculinization of the fetus in this context. Oxytocin (Choice D) is a hormone involved in labor and breastfeeding, but it is not used to prevent miscarriages nor does it cause masculinization of the fetus.
5. A client is experiencing preterm labor and has a prescription for 4 doses of dexamethasone 6 mg IM every 12 hours. The available concentration is dexamethasone 10 mg/mL. How many mL of dexamethasone should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use trailing zero.)
- A. 0.6 mL
- B. ---
- C. ---
- D. ---
Correct answer: A
Rationale: Calculation: (6 mg/dose) / (10 mg/mL) = 0.6 mL per dose. The correct answer is 0.6 mL. This calculation is obtained by dividing the dose needed (6 mg) by the concentration available (10 mg/mL). The resulting value is 0.6 mL per dose. Choices B, C, and D are not applicable as the correct answer has been calculated accurately.
