NCLEX-RN Complete Prep Course — Lesson 38: Newborn Assessment and Care: Apgar, Vital Signs, Reflexes, Thermoregulation, Jaundice, and Feeding
Sarah Mitchell scores an Apgar, reviews normal newborn vital signs and the distress signs that are not normal, and explains why cold stress leads to hypoglycemia and acidosis. She covers vitamin K, eye prophylaxis, hepatitis B, cord care, p
MATSEC AM Pure Mathematics Complete Prep Course — Lesson 37: Tangents and contact of circles
Sarah Mitchell derives the tangent at a point on a circle from the perpendicular radius property, then finds tangents of a given gradient using the perpendicular distance from the centre and the zero discriminant test. She covers the two eq
NCLEX-RN Complete Prep Course — Lesson 37: Postpartum Care and Complications: Fundal Checks, Lochia, Hemorrhage, Infection, and Postpartum Depression
Sarah Mitchell walks through the BUBBLE-HE postpartum assessment, the fundus and lochia numbers that separate normal recovery from hemorrhage, and the uterotonic sequence with the contraindications for methylergonovine and carboprost. She c
MATSEC AM Pure Mathematics Complete Prep Course — Lesson 36: The circle: both general forms
Sarah Mitchell teaches the two equations of a circle for MATSEC Paper One. She moves between centre-radius form and the expanded form with two g x and two f y, reading the centre as minus g, minus f and the radius as the square root of g sq
NCLEX-RN Complete Prep Course — Lesson 36: High-Risk Pregnancy: Preeclampsia, Gestational Diabetes, Placenta Previa, Abruption, Ectopic Pregnancy, and HELLP
Sarah Mitchell covers the pregnancy complications that generate bow-tie and priority questions: gestational hypertension, preeclampsia with severe features, and eclampsia; magnesium sulfate dosing, therapeutic range, the ordered toxicity si
MATSEC AM Pure Mathematics Complete Prep Course — Lesson 35: Loci and parametric coordinates
Sarah shows how to turn a verbal description of a moving point into an equation by letting the point be x and y, then clearing roots and fractions. She names the standard loci, circle, perpendicular bisector, angle bisectors, the circle of
NCLEX-RN Complete Prep Course — Lesson 35: Labor and Delivery: Stages of Labor, Fetal Heart Rate Monitoring, and Nursing Interventions
Sarah Mitchell separates true from false labor, explains the five P's, dilation, effacement, and station, then walks through the four stages of labor with the nursing care in each. She teaches the fetal heart rate baseline of 110 to 160, va
MATSEC AM Pure Mathematics Complete Prep Course — Lesson 34: Perpendicular distance from a point to a line
Sarah Mitchell teaches the perpendicular distance formula for MATSEC Advanced Matriculation Pure Mathematics: the modulus of a x-one plus b y-one plus c over the square root of a squared plus b squared. She stresses rewriting the line in ge
NCLEX-RN Complete Prep Course — Lesson 34: Antepartum Care: Prenatal Visits, Fetal Development, Nutrition, and Warning Signs
Sarah Mitchell walks through the normal pregnancy the NCLEX expects before the complications: GTPAL and Naegele's rule with worked examples, presumptive, probable, and positive signs, the visit schedule and fundal height rule, which prenata
MATSEC AM Pure Mathematics Complete Prep Course — Lesson 33: Intersection and angle between two lines
This lesson shows how to locate where two straight lines cross by solving their equations simultaneously, and how to find the acute angle between them using the modulus form of the tangent formula. It covers parallel and identical line case
