The MAIN clinical feature of puerperal psychosis is

Correct Answer: C

Rationale: The correct answer is C, major depression. Puerperal psychosis is a severe mental health condition that occurs in the postpartum period, characterized by symptoms such as hallucinations, delusions, and disorganized thinking. Major depression is a key clinical feature, often accompanied by mood disturbances and severe emotional distress. Rationale: - A: Episodic insomnia is a common symptom in various mental health disorders but not specific to puerperal psychosis. - B: Neglect of hygiene may occur in severe cases but is not the main clinical feature of puerperal psychosis. - D: Mild headache is not a characteristic symptom of puerperal psychosis, which is primarily marked by severe psychiatric symptoms.

Correct Answer: A

Rationale: The correct answer is A: Bradycardia. Hypothermia neonatorum is characterized by low body temperature in newborns, which can lead to bradycardia as the heart rate decreases in response to the cold stress. Bradycardia is a common physiological response to hypothermia as the body tries to conserve energy and maintain vital functions. Hyperglycemia, hypoventilation, and hyperventilation are not specific clinical features of hypothermia neonatorum. Hyperglycemia is more commonly associated with conditions like diabetes, hypoventilation could be a sign of respiratory distress, and hyperventilation is usually seen in response to metabolic acidosis or anxiety.

Correct Answer: B

Rationale: In the management of hypothermia neonatorum, the gradual rewarming process is aimed at preventing shock. Rapid rewarming can lead to vasodilation, causing a sudden drop in blood pressure and potentially leading to shock. Gradual rewarming helps the body adjust slowly to prevent this. Providing energy (Choice A) is not the primary goal of rewarming in hypothermia. Providing comfort (Choice C) is important but not the main purpose of the rewarming process. Preventing burns (Choice D) is not directly related to the rewarming process but is important to ensure the safety of the neonate during the rewarming process.

Correct Answer: D

Rationale: The correct answer is D, postpartum eclampsia. In amniotic fluid embolism, convulsions are often mistaken for postpartum eclampsia due to similar symptoms such as seizures and altered mental status. Postpartum eclampsia occurs after delivery, usually within 48 hours, while antepartum eclampsia occurs before delivery. Presence of stroke and pre-existing epilepsy are not directly related to convulsions in amniotic fluid embolism. Thus, D is the correct choice as it closely resembles the presentation of convulsions in amniotic fluid embolism.

Correct Answer: B

Rationale: Classical vitamin K deficiency bleeding occurs within the neonatal stage because newborns have low levels of vitamin K, which is essential for blood clotting. This deficiency typically manifests between 1-7 days after birth. Bleeding within the first 24 hours (choice A) is unlikely as it is too early for vitamin K deficiency to cause symptoms. Bleeding within infancy (choice C) is incorrect as it specifically refers to the neonatal stage. Bleeding within the first week of birth (choice D) is a close distractor, but the critical period for classical vitamin K deficiency bleeding is within the neonatal stage, which is slightly more specific than the first week of birth.
