What is a common cause of oligohydramnios during pregnancy?
- A. Maternal hypertension
- B. Multiple gestations
- C. Premature rupture of membranes
- D. Fetal macrosomia
Correct Answer: C
Rationale: The correct answer is C: Premature rupture of membranes. Oligohydramnios is a condition characterized by low levels of amniotic fluid which can be caused by the premature rupture of membranes, leading to the leakage of amniotic fluid. This condition can result in various complications such as fetal growth restriction and compression of the umbilical cord. Maternal hypertension (choice A) is not a direct cause of oligohydramnios. Multiple gestations (choice B) may lead to polyhydramnios (excessive amniotic fluid) rather than oligohydramnios. Fetal macrosomia (choice D) is associated with increased amniotic fluid levels rather than decreased levels seen in oligohydramnios.

Icterus gravis and hydrops fetalis are conditions highly associated with:
- A. Rhesus D incompatibility
- B. ABO incompatibility
- C. Physiological jaundice
- D. Instant perinatal death
Correct Answer: A
Rationale: The correct answer is A: Rhesus D incompatibility. Icterus gravis and hydrops fetalis are conditions associated with hemolytic disease of the newborn, caused by Rhesus D incompatibility between the mother and fetus. This occurs when the mother is Rh-negative and the baby is Rh-positive, leading to the production of antibodies by the mother that attack the baby's red blood cells. This can result in severe jaundice (icterus gravis) and excessive fluid accumulation in the fetus (hydrops fetalis).
Summary:
- Choice B (ABO incompatibility) is incorrect because it typically causes less severe jaundice and anemia compared to Rhesus D incompatibility.
- Choice C (Physiological jaundice) is incorrect as it is a common benign condition in newborns due to immature liver function.
- Choice D (Instant perinatal death) is incorrect as it does not specifically relate to the conditions mentioned.
Flexion-distraction injuries of the thoracolumbar spine are most commonly caused by
- A. Blunt trauma
- B. Rotational injury
- C. Seat belts
- D. Gunshot wounds
Correct Answer: B
Rationale: The correct answer is B: Rotational injury. Flexion-distraction injuries of the thoracolumbar spine are often caused by rotational forces that occur during accidents such as motor vehicle collisions or falls. These forces lead to the spine being twisted, causing separation of the vertebrae. Blunt trauma (A) can cause various spinal injuries but is not specific to flexion-distraction injuries. Seat belts (C) are designed to prevent spinal injuries by restraining the body during a collision. Gunshot wounds (D) can cause spinal cord injuries but are not commonly associated with flexion-distraction injuries of the thoracolumbar spine.
During induction of labor with syntocinon, drops increase is stopped prematurely on
- A. Achieving three moderate contractions
- B. Realizing normal maternal observations
- C. Achieving progressive cervical dilatation
- D. Observing normal fetal-related observations
Correct Answer: C
Rationale: Step-by-step rationale for choice C:
1. Progressive cervical dilatation indicates effective labor progress.
2. Stopping the syntocinon drops prematurely allows natural labor progression.
3. Prematurely stopping drops before reaching full dilation may hinder labor.
4. Achieving cervical dilatation is a crucial indicator for successful labor.
Summary:
A: Contractions should be strong, not just moderate.
B: Maternal observations alone do not determine labor progress.
D: Fetal-related observations are important but not the primary indicator for stopping drops.
Which of the following is not a true statement with respect to decision making for a cognitively impaired patient?
- A. Only a court can declare a patient incompetent
- B. Impaired cognition does not make a person incompetent
- C. Living wills typically are honored if a person is terminally ill
- D. A patient can give informed consent if not declared incompetent
Correct Answer: C
Rationale: The correct answer is C because living wills are typically not honored for terminally ill patients with impaired cognition. Firstly, living wills require the patient to be of sound mind to make decisions. Secondly, in the case of a cognitively impaired patient, their ability to express their wishes and understand the implications may be compromised. Therefore, healthcare providers may not be able to honor the living will accurately. Choices A, B, and D are incorrect because A) competency can be determined by healthcare professionals, B) impaired cognition can lead to incompetence, and D) informed consent requires the patient to understand the decision-making process.
Mother-to-child transmission of TB organisms never occurs during labor.
- A. TRUE
- B. FALSE
- C. -
- D. -
Correct Answer: B
Rationale: Step 1: TB can be transmitted through respiratory droplets, not just during labor.
Step 2: Mother with active TB can transmit the bacteria to the child during childbirth.
Step 3: Therefore, the statement that mother-to-child transmission never occurs during labor is false.
Summary: Choice B is correct because TB transmission can occur during labor, making Choice A incorrect. Choices C and D are irrelevant.
