AMCB Flashcards Review

Latent Phase of Labor

• Marks the beginning of labor until cervical dilation reaches 4-6 cm.

Long Arc Rotation

• A maneuver most commonly initiated by babies in a Left Occiput Posterior (LOP) presentation during labor.

FHR Variability Control

• Influenced by the parasympathetic and sympathetic nervous systems.

Pudendal Anesthesia Timing

• In multiparous women, administration is ideal at 8-9 cm dilation to cover delivery and any necessary repairs.

Sudden Fetal Bradycardia

• Often linked to a vagal response during fetal descent in the second stage of labor.

Engagement in Labor

• Occurs when the widest diameter of the presenting part descends to or below the pelvic inlet; specifically, the biparietal diameter of the fetal head.

Iron Deficiency Labs

• Indicators include microcytic, hypochromic anemia with low hemoglobin, hematocrit, MCV, MCHC, RBC count, iron, and ferritin, alongside high TIBC and RDW.

Relief for Leg Cramps in Pregnancy

• Flexing the foot can alleviate discomfort caused by leg cramps.

Respiratory System Changes in Pregnancy

• Increased chest diameter and thoracic circumference (up by 5-6 cm), with reduced residual volume.

Polyhydramnios Fetal Causes

• Can result from central nervous system or gastrointestinal tract anomalies in the fetus.

Autosomal Recessive Traits

• Manifest only when both gene copies are identical; examples include cystic fibrosis and sickle cell anemia.

Effects of Maternal Tobacco Use

• Associated with intrauterine growth restriction (IUGR), preterm birth, and small-for-gestational-age (SGA) infants.

Severe Features of Preeclampsia

• Characterized by thrombocytopenia, renal insufficiency, impaired liver function, pulmonary edema, and neurological symptoms.

Hemodynamic Changes Postpartum

• Cardiac output can increase by 60-80% and remain elevated for up to 48 hours after childbirth.

Placental Transport Mechanisms

• Oxygen and glucose are transferred across the placenta via facilitated diffusion.

Amniotic Fluid Production Mechanisms

• Generated by the amniotic epithelium; during the second trimester, the fetus begins to swallow, urinate, and inspire amniotic fluid.

Trichomoniasis Treatment in Pregnancy

• Metronidazole (Flagyl) is prescribed as a single 2 g oral dose at any stage of pregnancy.

Ritgen Maneuver

• A technique to facilitate fetal head delivery by applying upward pressure from the coccygeal region during extension, protecting perineal musculature.

Contraindications for Breastfeeding

• Include being HIV positive (untreated), having active tuberculosis, ongoing illicit drug use, or taking prescribed chemotherapy medications.

Acrocyanosis in Newborns

• A bluish discoloration of the extremities due to reduced peripheral circulation, common and normal within the first 24-48 hours after birth.

Variable Decelerations Description

• Abrupt FHR decreases exceeding 15 BPM for over 15 seconds, indicating potential fetal distress.

Ezetimibe

• A drug used alongside moderate-intensity statins for dyslipidemia when patients can't tolerate high-intensity statins, working by inhibiting cholesterol absorption.

Types of Leiomyomata

• Include submucosal, subserosal, intraligamentous, interstitial (intramural), and pedunculated myomas, affecting the uterus in various ways.

Human Zygote Characteristics

• Contains 23 pairs of chromosomes (haploid number) or 46 total (diploid number) found in body cells.

Sexual Dysfunction DSM-5 Criteria

• Symptoms must occur at least 75% of the time over a minimum of six months and cause significant distress.

Risk Factors for Endometrial Carcinoma

• Include diabetes, obesity, hypertension, early menarche, late menopause, unopposed estrogen therapy, oligo-ovulation, anovulation, and estrogen-secreting tumors.

Community-acquired Pneumonia Treatment

• Outpatient treatment typically involves azithromycin, clarithromycin, or doxycycline; risk factors suggest respiratory fluoroquinolone use.

Safety Bundle Concept

• Comprises small, evidence-based practices that enhance patient outcomes when implemented collectively.

Mammary Changes During Pregnancy

• Include Montgomery tubercles enlargement, darkened areolas, enlarged breasts, and more visible blood vessels.

Initial Neonatal Resuscitation Steps

• Involve placing the infant under a radiant heater, clearing secretions, drying, and providing tactile stimulation while assessing vital signs.

Differential Diagnosis for First Trimester Bleeding

• Conditions include implantation bleeding, threatened abortion, ectopic pregnancy, cervicitis, cervical polyps, vaginitis, trauma, or disappearing twin.

Definition of Multigravida

• Refers to a person who has been pregnant two or more times, regardless of pregnancy outcomes.

Moderate FHR Variability

• Defined by an amplitude range of 6-25 BPM, indicating a stable fetal state.

Ospemifene

• A selective estrogen receptor modulator (SERM) used for treating moderate to severe dyspareunia associated with vulvovaginal atrophy; may cause hot flashes as a side effect.
