A couple has been diagnosed with infertility after trying to conceive for a year.
Which test would likely be performed first?
Semen analysis
Transvaginal ultrasound
Hysterosalpingography
Hysteroscopy
The Correct Answer is A
Choice A rationale:
Semen analysis is the initial test often performed in the evaluation of infertility. It's a non-invasive, cost-effective, and informative assessment of male fertility. Here's a detailed explanation of its significance:
Assessment of Sperm Quality:
Measures sperm count, motility (movement), and morphology (shape).
Abnormalities in any of these parameters can significantly impact the chances of conception.
Identification of Male Factor Infertility:
Contributes to approximately 40% of infertility cases.
Early identification of male factor infertility guides treatment options and avoids unnecessary testing for the female partner.
Non-Invasive and Cost-Effective:
Simple procedure involving the collection of a semen sample.
Relatively inexpensive compared to other fertility tests.
Informative Results:
Provides valuable insights into sperm health and potential causes of infertility.
Guides further diagnostic evaluation and treatment strategies.
Rationale for other choices:
Choice B: Transvaginal ultrasound
Primarily evaluates female reproductive organs.
Assesses uterine structure, ovarian function, and potential abnormalities like fibroids or cysts.
Not typically the first test in infertility evaluation unless there's a specific female-factor concern.
Choice C: Hysterosalpingography (HSG)
Assesses the patency of the fallopian tubes.
Involves X-ray imaging after injecting contrast dye into the uterus.
Often performed after semen analysis if male factor infertility is not identified.
Choice D: Hysteroscopy
A more invasive procedure involving direct visualization of the inside of the uterus.
Used to diagnose and treat uterine abnormalities such as polyps or fibroids.
Not typically a first-line test in infertility evaluation.

Correct Answer is C
Explanation
Choice A rationale:
Effleurage is a gentle massage technique often used in labor to promote relaxation and reduce discomfort. It involves using light, stroking movements over the abdomen or back. While effleurage can be soothing for some women, it may not be as effective for specifically addressing the intense back pain associated with back labor. It is more focused on general relaxation than on targeted pain relief in the sacral region.
Choice B rationale:
Pant-blow (breaths and puffs) breathing techniques are commonly taught in childbirth classes as a way to manage labor pain. They involve using specific patterns of breathing to help control contractions and minimize discomfort. While these techniques can be helpful for some women, they may not be as effective for back labor pain as they are primarily focused on managing the sensations of contractions in the abdomen and uterus. They don't directly address the sacral pain that characterizes back labor.
Choice C rationale:
Counterpressure against the sacrum is a specific technique that can be very effective for relieving back labor pain. It involves applying firm, steady pressure to the lower back, specifically the sacral area, using the hands, a fist, or a tennis ball. This pressure can help to counteract the intense sensations of pain and pressure in the lower back, providing significant relief. The mechanism behind this relief is likely related to:
Gate-control theory: Counterpressure may stimulate other nerve pathways, which can block or reduce pain signals from reaching the brain.
Counteracting pressure: The pressure applied to the sacrum may help to counteract the internal pressure of the baby's head against the sacrum, which can be a major source of back labor pain.
Muscle relaxation: Firm pressure can help to relax tense muscles in the lower back, which can contribute to pain.
Choice D rationale:
Conscious relaxation or guided imagery are techniques that can promote overall relaxation and reduce anxiety during labor. They involve using mental exercises to focus the mind on calming images or sensations. While these techniques can be helpful for some women, they may not be as effective for specifically targeting back labor pain as they are more general relaxation methods that don't directly address the sacral pain.
Correct Answer is ["A","D"]
Explanation
Choice A rationale:
Prostaglandins:
Mechanism of action: Prostaglandins are hormone-like substances that play a crucial role in labor initiation. They act by softening and ripening the cervix, stimulating uterine contractions, and rupturing the amniotic sac.
Types: Prostaglandins used for labor induction include:
Dinoprostone (Cervidil, Prepidil): Inserted into the vagina as a gel or pessary.
Misoprostol (Cytotec): Administered orally or vaginally.
Effectiveness: Generally effective in initiating labor within 24 hours, with success rates ranging from 60-85%.
Advantages:
Can be used when the cervix is unfavorable (not ripe).
Can be administered in a variety of ways to suit the patient's preferences.
May have a lower risk of uterine hyperstimulation compared to oxytocin.
Disadvantages:
Can cause side effects such as nausea, vomiting, diarrhea, and fever.
May increase the risk of uterine rupture, especially in women with a history of cesarean delivery.
Choice D rationale:
Amnioinfusion:
Procedure: Involves the infusion of sterile saline solution into the amniotic sac through a small catheter.
Mechanism of action: Not fully understood, but it's thought to work by:
Increasing amniotic fluid volume, which can help to stimulate contractions.
Stretching the uterine walls, which may trigger the release of prostaglandins.
Reducing pressure on the umbilical cord, which can improve fetal oxygenation.
Effectiveness: Usually used in conjunction with other induction methods, such as oxytocin or prostaglandins. Has a success rate of about 50-60% in initiating labor within 24 hours.
Advantages:
May be helpful in cases of low amniotic fluid (oligohydramnios).
Can decrease the risk of umbilical cord compression.
Disadvantages:
Requires the insertion of a catheter into the uterus, which carries a small risk of infection.
May cause discomfort for the mother.
