A nurse is assessing a full-term newborn. Which of the following findings should the nurse report to the provider?
Respiratory rate 55/min
Blood pressure 80/50 mm Hg
Temperature 36.5°C (97.7°F)
Heart rate 72/min
The Correct Answer is D
Heart rate is one of the vital signs that reflects the health and well-being of a newborn. It is measured by counting the number of heart beats per minute, either by listening to the chest with a stethoscope or by feeling the pulse at the wrist, elbow, or groin. Heart rate can vary depending on the newborn's activity level, temperature, and emotional state¹.
The normal range for heart rate in full-term newborns is 120 to 160 beats per minute. The heart rate may be slightly higher or lower depending on the newborn's age, weight, and gestational age. For example, premature newborns may have a higher heart rate than term newborns, and heavier newborns may have a lower heart rate than lighter newborns¹².
A heart rate that is too high (tachycardia) or too low (bradycardia) can indicate a problem with the newborn's heart function, oxygenation, or circulation. Some of the possible causes of abnormal heart rate in newborns are:
- Congenital heart defects: structural abnormalities of the heart that are present at birth and affect the blood flow through the heart and the body. They can cause cyanosis (bluish skin color), murmur (abnormal heart sound), poor feeding, or failure to thrive¹³.
- Arrhythmias: irregular or abnormal heart rhythms that can affect the electrical impulses that control the heartbeat. They can cause palpitations (feeling of skipped or extra beats), dizziness, fainting, or cardiac arrest¹³.
- Hypoxia: lack of oxygen in the blood or tissues that can affect the brain and other organs. It can be caused by respiratory distress, anemia, infection, or birth asphyxia. It can cause bradycardia, apnea (pauses in breathing), seizures, or coma¹⁴.
- Hypothermia: low body temperature that can affect the metabolism and organ function. It can be caused by exposure to cold environment, infection, or prematurity. It can cause bradycardia, lethargy, poor feeding, or hypoglycemia (low blood sugar)¹⁴.
- Sepsis: severe infection that can affect the whole body and cause inflammation and organ damage. It can be caused by bacteria, viruses, fungi, or parasites that enter the bloodstream from the mother, the umbilical cord, or the environment. It can cause tachycardia, fever, chills, poor feeding, or shock¹⁴.
Therefore, the nurse should report a heart rate of 72/min to the provider as an abnormal finding and monitor the newborn for any other signs of distress or illness. The provider may order further tests or treatments to determine the cause and severity of the low heart rate and prevent any complications.
The other findings are not findings that the nurse should report to the provider because they are within the
normal range for full-term newborns:
- a) Respiratory rate 55/min is within the normal range for respiratory rate in full-term newborns. The normal range for respiratory rate in full-term newborns is 40 to 60 breaths per minute. The respiratory rate may vary depending on the newborn's activity level, temperature and emotional state¹².
- b) Blood pressure 80/50 mm Hg is within the normal range for blood pressure in full-term newborns. The normal range for blood pressure in full-term newborns is 65 to 95 mm Hg for systolic pressure (the top number) and 30 to 60 mm Hg for diastolic pressure (the bottom number). The blood pressure may vary depending on the newborn's age, weight, and gestational age¹².
- c) Temperature 36.5°C (97.7°F) is within the normal range for temperature in full-term newborns. The normal range for temperature in full-term newborns is 36.5°C to 37.5°C (97.7°F to 99.5°F). The temperature may vary depending on the newborn's activity level, clothing, and environment¹².

Correct Answer is C
Explanation
Nägele's Rule is a common method used to estimate the expected date of delivery (EDD) based on the first day of the client's last menstrual period (LMP). According to Nägele's Rule, you subtract 3 months from the LMP date and add 7 days, then adjust the year if necessary.
In this case, the first day of the client's last menstrual period was August 10. Subtracting 3 months gives us May 10. Adding 7 days gives us May 17. Therefore, the estimated date of delivery for this client is May 17.
Correct Answer is C
Explanation
Postpartum hemorrhage (PPH) is severe vaginal bleeding after childbirth. It can occur within 24 hours of delivery (primary PPH) or up to 12 weeks postpartum (secondary PPH) ¹. PPH can cause serious complications and even death if not treated promptly and effectively¹.
The client in the question is at risk for PPH because she has a rapid labor and a high degree of cervical dilation. These factors can cause uterine atony, which is the failure of the uterus to contract and compress the blood vessels after delivery. Uterine atony is the most common cause of PPH, accounting for up to 80% of cases². Other risk factors for PPH include placental abruption, placenta previa, overdistended uterus, multiple pregnancy, prolonged labor, operative delivery, retained placenta, coagulation disorders, and infection²³.
a) Hyperemesis gravidarum is a condition of severe nausea and vomiting during pregnancy that can cause dehydration, electrolyte imbalance, weight loss, and nutritional deficiencies. It usually occurs in the first trimester and resolves by the second trimester. It is not related to PPH⁴.
b) Ectopic pregnancy is a condition where the fertilized egg implants outside the uterus, usually in the fallopian tube. It can cause abdominal pain, vaginal bleeding, and rupture of the tube. It is a medical emergency that requires prompt diagnosis and treatment. It occurs in early pregnancy and cannot be diagnosed at 12 weeks of gestation by amniocentesis.
d) Incompetent cervix is a condition where the cervix dilates prematurely and painlessly during pregnancy, leading to preterm labor and delivery or pregnancy loss. It usually occurs in the second trimester and can be treated with cervical cerclage or progesterone. It is not associated with PPH.
