A new mother is changing the diaper of her 12-hour-old newborn and asks why the stool is black and sticky. Which response by the nurse would be most appropriate?

"This is meconium stool and is normal for a newborn."

"You probably took iron during your pregnancy and that is what causes this type of stool."

“ This is unusual, and I need to report this to your pediatrician."

I'll take a sample and check it for possible bleeding"

Answer and Explanation

The Correct Answer is A

A. "This is meconium stool and is normal for a newborn." is the correct and most appropriate response. Meconium is the newborn’s first stool, typically passed within the first 24 to 48 hours of life. It is black, tarry, and sticky in appearance and consists of materials the baby ingested while in the womb, such as amniotic fluid, mucus, and cells. It is completely normal and expected.

B. "You probably took iron during your pregnancy and that is what causes this type of stool." is incorrect. While iron supplements can darken adult stools, meconium is unrelated to maternal iron intake and is a normal physiological occurrence in all newborns.

C. “This is unusual, and I need to report this to your pediatrician." is incorrect and would be alarming to the parent unnecessarily. This is a normal finding, not something requiring physician notification.

D. "I'll take a sample and check it for possible bleeding" is also inappropriate unless there are other signs of concern (e.g., blood in stool later on). Meconium is not indicative of bleeding and does not warrant testing under normal circumstances.

Correct Answer is B

Explanation

A. 50mg/hr is not the correct unit for volume, it’s the dose in milligrams.
B. 50 mL/hr is the correct volume to administer to achieve the ordered dose of 2g/hr. Determine the concentration of the solution: The supply is 10g in 250mL. This means the concentration is 10g / 250mL, or 0.04g/mL (since 10g = 10,000mg, this is equivalent to 40mg/mL). Convert the ordered dose to match the concentration: The order is for 2g/hr (which is 2,000mg/hr). Calculate the volume to be infused to deliver the desired dose: Dose = Ordered/concentration= 2000/40= 50 mL/hr
C. 5mg/mL refers to the concentration, not the rate of infusion.
D. 5 mL/hr would administer only 200mg/hr, which is much lower than the ordered dose of 2g/hr.

A. 7 B. 8 C. 5 D. 9

Correct Answer is B

Explanation

A. A score of 7 would be given if the infant’s heart rate was 100, but with less than optimal responses for color, muscle tone, and respiratory effort. However, this baby demonstrates strong responses in all categories.

B. The Apgar score is calculated based on five criteria: heart rate, respiratory effort, muscle tone, reflex irritability, and color. The infant in the scenario has:

Heart rate of 100 (score 2)

Pink body and blue hands (score 1 for color—because the baby is not fully pink, indicating some cyanosis in the extremities)

Active motion (score 2 for muscle tone)

Strong lusty cry (score 2 for reflex irritability/responsiveness to stimuli)

Good respirations (score 2)

Adding these scores (2 + 1 + 2 + 2 + 2), the total is 8.

C. A score of 5 would indicate more significant distress, with poor color, respiratory effort, and muscle tone. This infant is showing good signs of adaptation.

D. A score of 9 would indicate that the baby has no signs of cyanosis and perfect responses in all categories, but since the infant has blue hands, it scores slightly lower (1 point less for color).
