The gradual rewarming process in the management of hypothermia neonatorum is aimed at

Correct Answer: C

Rationale: The primary goal of gradual rewarming is to prevent shock and stabilize the neonate's condition.

Correct Answer: B

Rationale: The patient's presentation with low blood pressure, tachycardia, tachypnea, decreased oxygen saturation, and altered mental status is most consistent with distributive shock. Distributive shock is characterized by systemic vasodilation and decreased systemic vascular resistance (SVR), leading to inadequate perfusion of tissues and organs despite normal or high cardiac output. In this case, the low SVR (1600 dynes ∙ sec/cm5) and low blood pressure indicate vasodilation. The patient's pulmonary capillary wedge pressure (PCWP) of 8 mm Hg is not consistent with cardiogenic shock, where elevated PCWP would be expected. Additionally, there are no signs of obstructive shock, such as a history of pulmonary embolism but rather clinical findings that suggest distributive shock. Hypovolemic shock would typically present with signs of volume depletion and would be less likely in this patient with stable mental status initially.

Correct Answer: C

Rationale: The Grey Turner sign is characterized by bruising in the flanks and is a rare finding associated with acute pancreatitis. It indicates retroperitoneal bleeding and is considered an ominous finding that suggests a severe and potentially moribund state in patients with acute pancreatitis. The presence of the Grey Turner sign should prompt immediate intervention and close monitoring in a hospital setting. The other options, severe epigastric pain with radiation to the back, abdominal guarding and rigidity, and obturator sign, are indicative of pancreatitis but do not carry the same ominous implication as the Grey Turner sign.

Correct Answer: B

Rationale: Puerperal psychosis often presents with manic episodes in the majority of cases.

Correct Answer: C

Rationale: Hypovolaemia from excessive bleeding can lead to renal failure.
