Psychosis during puerperium mostly manifests as

Correct Answer: C

Rationale: The correct answer is C: Depression. Psychosis during puerperium commonly manifests as postpartum depression, characterized by feelings of extreme sadness, anxiety, and fatigue. This is due to hormonal changes and stress associated with childbirth. Mania (choice A) and bipolar disorder (choice B) are less common during this period. Infection (choice D) is not a typical manifestation of psychosis during puerperium. Overall, postpartum depression is the most prevalent and well-documented form of psychosis in the postpartum period.

Correct Answer: A

Rationale: The correct answer is A: Prevent alveoli of the lungs from collapsing. Surfactant reduces surface tension in the alveoli, preventing them from collapsing during exhalation and maintaining lung compliance. B, C, and D are incorrect because surfactant primarily affects lung mechanics, not the initiation of breathing, maturity of the respiratory center, or immediate regulation of breathing upon birth.

Correct Answer: A

Rationale: The correct answer is A: Rhesus D incompatibility. Icterus gravis (severe jaundice) and hydrops fetalis (abnormal accumulation of fluid) are both conditions commonly associated with Rhesus D incompatibility between a mother and her fetus. This occurs when the mother is Rh-negative and the fetus is Rh-positive, leading to maternal antibodies attacking the fetal red blood cells, resulting in severe hemolytic anemia and subsequent complications. Explanation for why other choices are incorrect: B: ABO incompatibility typically leads to less severe jaundice and hemolytic disease compared to Rhesus D incompatibility. C: Physiological jaundice is a common and benign condition in newborns caused by the immaturity of the liver, not by blood type incompatibility. D: Instant perinatal death is not specifically associated with these conditions, but rather with other serious complications during childbirth.

Correct Answer: C

Rationale: The correct answer is C: Very low birth weight neonate. This designation is given to infants whose birth weight is less than 1500 grams. In this case, the neonate's weight of 1201 grams falls within the criteria for very low birth weight. Choice A is incorrect because being genetically small does not necessarily equate to low birth weight. Choice B is incorrect as low birth weight typically refers to infants weighing between 1500-2499 grams. Choice D is incorrect as extremely low birth weight pertains to infants weighing less than 1000 grams.

Correct Answer: B

Rationale: In uterine inversion, the fundus is the last part to be replaced due to its position being the deepest inside the vagina. The fundus is the upper portion of the uterus and is the last part to invert back into its normal position. The cervix, isthmus, and body are parts of the uterus that are more easily replaced during the process of uterine inversion. The fundus being the final part to be replaced ensures the uterus is fully restored to its correct orientation.
