What is the process of ejaculation (2)?

• Sympathetic impulses• Urethra fills with semen• Contraction of muscles at the base of the

penis• Pressure forces semen through urethra

resolution• D. Excitement, ejaculation, resolution• E. Excitement, plateau, orgasmic, resolution

• B. 2 umbilical arteries carrying oxygenated blood and one umbilical vein carrying deoxygenated blood

• C. 2 umbilical arteries carrying deoxygenated blood and one umbilical vein carrying oxygenated blood

• D. 1 umbilical artery carrying deoxygenated blood and 2 umbilical veins carrying oxygenated blood

• E. 1 umbilical artery carrying deoxygenated blood and 1 umbilical vein carrying oxygenated blood

Give three forms of transport across the placenta? (3)

What is transported across the placenta by simple diffusion?

• A. Oxygen• B. Iron• C. Glucose• D. Amino Acids• E. Globulins

Give three factors that affect the onset of puberty. (3)

• Malnutrition• Chronic disease (renal failure, CCF, Crohn’s)• Low BMI• High BMI• Exercise in females• Endocrine (thyroid, adrenal)• Genetic factors• Black girls develop earlier than white • Emotional deprivation

What is the classical symptom triad of the menopause? (3)

• Hot flushes• Sweats• Vaginal dryness

Explain the process of cervical ripening. (2)

• Marked reduction in collagen and increase in glycosaminoglycans which decrease the aggregation of collagen fibres

• Collagen bundles ‘loosen’• Influx of inflammatory cells, and increase in

nitric oxide output• All changes are triggered by prostaglandins

What is brachystasis? (2)

• At each contraction muscle fibres shorten, but do not relax fully

• The uterus, particularly the fundus shortens progressively

• Pushes the presenting part towards the birth canal and stretches or dilates the cervix over it

When does the first stage of labour end?

• A. When the cervix begins to dilate• B. When the cervix is fully dilated• C. When the head is delivered• D. When the baby is delivered• E. When the placenta is delivered

How is the risk of tearing to the perineum and vagina reduced? (1)

• Episiotomy

What happens in the third stage of labour? (3)

• Powerful uterine contractions, which separates the placenta, positioning it in the upper part of the vagina

• Placenta and the membranes are then expelled

• Contraction of the uterus compresses blood vessels and reduced bleeding

What are the three elements of labour?

• A. Pain, Passenger, Passage• B. Powers, Pain, Passage• C. Passage, Pain, Passenger• D. Powers, Passage, Passenger• E. Powers, Passenger, Parturition

Name three foetal presentations (3)

• Vertex – cephalic presentation• Breech• Shoulder• Face – complete extension • Brow – partial extension

Give three methods of induction. (3)

• Membrane sweep• Prostaglandins (PGE2) – vaginally• Artificial rupture of membranes• Oxytocin – given as infusion

What is meconium and what is the significance of it being present in the liquor? (2)

• First stool, blackish green and tenacious• Presence in liquor may be indicative of foetal

distress
