Calculate the gravity rate for gentamycin 100 mg/100ml with secondary tubing (20gtts/mL) over 60 minutes.
The Correct Answer is ["33"]
Given:
Total volume to infuse: 100 mL
Infusion time: 60 minutes
Drop factor of tubing: 20 gtt/mL
To find:
Drip rate (gtt/min)
Step 1: Calculate the total number of drops
Total drops = Total volume x Drop factor
Total drops = 100 mL x 20 gtt/mL = 2000 gtt
Step 2: Calculate the drip rate
Drip rate = Total drops / Infusion time in minutes
Drip rate = 2000 gtt / 60 minutes = 33.33 gtt/min
Step 3: Round to the nearest whole number
33 gtt/min.

Explanation
The newborn's assessment findings that require follow-up:
Temperature 35.7°C (96.3°F) at 2200:
Hypothermia in newborns can lead to cold stress, which increases the risk of respiratory distress and hypoglycemia. The newborn’s temperature should be closely monitored, and warming measures should be initiated to prevent further complications.
Respiratory rate 68/min at 2200:
A respiratory rate above 60 breaths per minute in a newborn is considered tachypnea and can indicate respiratory distress or underlying conditions such as infection. The newborn should be further evaluated to determine the cause of the tachypnea and to ensure proper oxygenation.
Sternal retractions at 2200:
Sternal retractions suggest that the newborn is experiencing increased work of breathing, which is a key sign of respiratory distress. This requires immediate evaluation to assess the severity and identify potential causes, such as respiratory infections or inadequate ventilation.
Coarse rhonchi in bilateral lung fields at 2200:
The presence of coarse rhonchi indicates abnormal breath sounds, often related to fluid retention or infection in the lungs. This finding requires further assessment and possibly interventions to clear the airway and support respiratory function.
Correct Answer is D
Explanation
A) At the umbilicus:
After delivery, the fundus is typically located at or just below the umbilicus in the immediate postpartum period, but it will gradually descend over the next few days. By 8 hours postpartum, the fundus is often slightly below the umbilicus, not directly at the umbilicus. The fundus will continue to shrink in size and move downward toward the pelvic region as the uterus contracts and involutes.
B) At a non-palpable depth:
A fundus that is non-palpable is generally expected later in the postpartum period, typically by 10-14 days after delivery, as the uterus contracts and returns to its pre-pregnancy size. At 8 hours postpartum, the fundus is still palpable, generally just below the umbilicus, and should be evaluated for firmness and position.
C) Just above the symphysis pubis:
The fundus is usually higher than the symphysis pubis at 8 hours postpartum, as it is still in the process of descending from the higher position it occupied during pregnancy. It would be expected to be just below the umbilicus or about 1 to 2 finger widths below it. By the second or third day postpartum, the fundus begins to move lower toward the symphysis pubis as it continues to involute.
D) Just below the umbilicus:
Eight hours after delivery, the nurse should expect to palpate the fundus just below the umbilicus. This is a typical finding as the uterus begins to contract and shrink after the delivery of the placenta. The fundus will descend about 1-2 cm per day postpartum, so by 8 hours, it is usually just slightly below the level of the umbilicus.
