In face presentation, obstructed labor is likely to result because

Correct Answer: A

Rationale: In face presentation, the face is an ill-fitting presenting part, leading to obstructed labor. The face has larger diameters, making it difficult to pass through the birth canal. This differs from vertex delivery where the head can mold to fit. Caput succedaneum is swelling of the soft tissues on the baby's head and does not directly cause obstructed labor.

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.

Correct Answer: B

Rationale: Step 1: Puerperal pyrexia refers to fever occurring after childbirth. Step 2: Causes can be obstetric (infection) or non-obstetric (e.g., urinary tract infection). Step 3: Non-obstetric causes are also common postpartum. Step 4: Therefore, puerperal pyrexia is not entirely obstetrically related. Step 5: Hence, the correct answer is B (FALSE).

Correct Answer: A

Rationale: The correct answer is A: Fever ≥ 38°C for three consecutive occasions. Puerperal pyrexia is defined as fever occurring after childbirth. The key diagnostic feature is the presence of fever (≥ 38°C) on three consecutive occasions, indicating a persistent infection. Choice B is incorrect because it doesn't specify the need for consecutive occasions. Choice C is incorrect as it extends the duration of fever to three weeks, which is too long for typical puerperal pyrexia. Choice D is incorrect as it mentions "occasionally" instead of "consecutively," which is not indicative of a consistent fever pattern seen in puerperal pyrexia.

Correct Answer: A

Rationale: The correct answer is A: 60 compressions coordinated with 30 breaths per minute. In neonatal resuscitation, the recommended compression-to-ventilation ratio is 3:1. This means 3 compressions are given followed by 1 breath. With a target compression rate of 120 per minute, this translates to 60 compressions coordinated with 30 breaths per minute. Each compression should be at a depth of about one-third the anterior-posterior diameter of the chest. This ratio and rate are crucial for maintaining adequate circulation and oxygenation during neonatal resuscitation. Choice B: 3 compressions coordinated with 1 breath per minute is too slow and would not provide enough support for the neonate's circulation. Choice C: 1 compression coordinated with 3 breaths per minute would not provide sufficient compressions to maintain circulation. Choice D: 90 compressions coordinated with 30 breaths per minute would result in an incorrect compression-to-vent
