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 B
Explanation
An ectopic pregnancy is a pregnancy that occurs outside the uterus, usually in the fallopian tube. The most common manifestation of an ectopic pregnancy is sharp pelvic pain, typically on one side. This pain is often described as severe and may be accompanied by shoulder pain or dizziness. The pain occurs because the fallopian tube is not designed to accommodate a growing embryo, leading to stretching and possible rupture of the tube.
Elevated blood pressure is not typically associated with an ectopic pregnancy. Blood pressure changes may occur in other conditions, such as preeclampsia, but it is not a characteristic manifestation of an ectopic pregnancy.
Bright red vaginal discharge is not a typical manifestation of an ectopic pregnancy. Vaginal bleeding may occur, but it is usually darker and more like a menstrual flow. Bright red vaginal discharge may indicate other conditions, such as a threatened miscarriage or a vaginal infection.
A scaphoid abdomen (a concave or sunken appearance of the abdomen) is not a specific manifestation of an ectopic pregnancy. It may be seen in conditions like malnutrition or dehydration, but it is not directly related to an ectopic pregnancy.
Correct Answer is B
Explanation
A. Using povidone-iodine on the site of a myelomeningocele is not recommended as it can be irritating to the tissue and might not be safe for use on open neural tissue. The focus should be on preventing infection through other means.
B. Administering broad-spectrum antibiotics is crucial as the cerebrospinal fluid (CSF) leak increases the risk of infection, such as meningitis. Antibiotics help protect the newborn from potentially serious infections until surgical repair can be performed.
C. Surgical closure of a myelomeningocele is typically done as soon as possible, often within 24-48 hours after birth, to minimize the risk of infection and further damage to the exposed spinal cord.
D. While monitoring temperature is important, rectal temperature measurement is not recommended for a newborn with a myelomeningocele due to the risk of causing further complications. Axillary temperature measurement would be safer and less invasive.
