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: Persistent vomiting or nausea. Hyperemesis gravidarum is a severe form of morning sickness characterized by persistent vomiting and nausea during pregnancy. This is the main clinical feature due to hormonal changes and increased sensitivity to certain odors. Choice B is incorrect as sight-related problems are not a typical feature of hyperemesis gravidarum. Choice C is incorrect as persistent diarrhea is not a defining feature of this condition. Choice D is incorrect as frequency or urgency of micturition is not a primary symptom of hyperemesis gravidarum.

Correct Answer: D

Rationale: The correct answer is D: Serotonin. Serotonin is not a primary chemical mediator of hepatic encephalopathy. The main chemical mediators involved in hepatic encephalopathy are A: Gamma-aminobutyric acid (GABA), B: Ammonia, and C: False neurotransmitters. GABA plays a role in inhibiting neurotransmission, ammonia is a key factor in the pathogenesis of hepatic encephalopathy, and false neurotransmitters are produced due to altered amino acid metabolism in the liver. Serotonin is not a key player in the development of hepatic encephalopathy, hence it is the correct answer.

Correct Answer: A

Rationale: The correct answer is A: TRUE. This is because BCG vaccination for newborns is recommended even if the mother is smear-negative for tuberculosis, as it helps protect the newborn from severe forms of TB. Smear status of the mother does not impact the need for BCG vaccination in the neonate. Choice B is incorrect as it falsely implies that BCG should not be given in this scenario. Choices C and D are not applicable as they do not provide any information.

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.
