Answers 2024/2025
What is the normal range for AST?
10 - 30 u/L
What is the normal range for ALT?
10 - 40 u/L
What is the normal range for Creatinine?
0.6 - 1.2 mg/dL
What is the normal range of hematocrit for women?
37 - 47%
What is the normal range for hemoglobin?
12 - 18 g/dL
What is the normal range for platelets?
150,000 - 400,000 cells/mcL
What is the normal FHR (fetal heart rate) range?
110 to 160 beats/min
How is fetal tachycardia defined?
As a baseline FHR greater than 160 beats/min for 10 minutes or longer.
How is fetal bradycardia defined?
As a baseline FHR less than 110 beats/min for 10 minutes or longer.
What three important questions does Leopold Maneuvers help to answer?
1.) Which fetal part is in the uterine fundus?
2.) Where is the fetal back located?
3.) What is the presenting fetal part?
How is category I defined in the fetal heart rate classification system?
1.) Baseline rate 110 to 160 beats/min
2.) Baseline FHR variability: Moderate
3.) Late or variable decelerations: Absent
4.) Early decelerations: Either present or absent
5.) Accelerations: Either present or absent:
How is category II defined in the fetal heart rate classification system?
1.) Bradycardia not accompanied by absent baseline variability, tachycardia
2.) Minimal baseline variability, absent baseline variability not accompanied by recurrent
decelerations, marked baseline variability
, 3.) No accelerations produced in response to fetal stimulation
4.) Recurrent variable decelerations accompanied by minimal or moderate baseline variability,
prolonged decelerations (greater than or equal to 7 minutes but less than 10 minutes, recurrent late
decelerations with moderate baseline variability, variable decelerations with other characteristics
such as slow return to baseline, "overshoots" or "shoulders"
How is category III defined in the fetal heart rate classification system?
1.) Absent baseline variability and any of the following: Recurrent late decelerations, recurrent
variable decelerations, bradycardia
2.) Sinusoidal pattern
How can Variability of the FHR be described?
As irregular waves or fluctuations in the baseline FHR of two cycles per minute or greater. It is a
characteristic of the baseline FHR and does not include accelerations or decelerations of the FHR.
Variability is quantified in beats per minute and is measured from the peak to the trough of a single
cycle.
What kind of Variability is considered normal?
Moderate
How are Accelerations of the FHR defined?
As a visually apparent abrupt onset to peak increase in FHR above the baseline rate. The peak is at
least 15 beats/min above the baseline, and the acceleration lasts 15 seconds or more, with the return
to baseline less than 2 minutes from the beginning of the acceleration.
What are the causes of Accelerations?
1.) Spontaneous fetal movement
2.) Vaginal examination
3.) Electrode application
4.) Fetal scalp application
5.) Fetal reaction to external sounds
6.) Breech presention
7.) Occiput posterior position
8.) Uterine contractions
9.) Fundal pressure
10.) Abdominal palpation
What are the nursing interventions for Accelerations?
None required.
What are Early Decelerations of the FHR?
A visually apparent, gradual decrease in and return to baseline FHR associated with uterine
contractions.
What are the causes of Early Decelerations?
Head compression resulting from the following:
1.) Uterine contractions
2.) Vaginal examination
3.) Fundal pressure
