Correct Answer: T

Rationale: Step-by-step rationale: 1. Puerperal psychosis is a severe mental health condition occurring postpartum. 2. Psychosocial adversities, such as stress or lack of social support, can trigger or exacerbate mental health issues. 3. Therefore, psychosocial adversities can be predisposing factors for puerperal psychosis. 4. Option A (TRUE) is correct as it aligns with the established relationship between psychosocial factors and mental health. Summary: Option A is correct because psychosocial adversities can indeed contribute to the development of puerperal psychosis, making it a relevant predisposing factor. Options B, C, and D are incorrect as they do not provide any rationale or evidence to support their validity.

Correct Answer: D

Rationale: The correct answer is D: Obturator sign. This finding indicates irritation of the peritoneum and is associated with a ruptured appendix, not acute pancreatitis. A: Severe epigastric pain with radiation to the back is a common presentation of acute pancreatitis, but not necessarily indicative of a seriously ill patient. B: Abdominal guarding and rigidity may suggest peritonitis but are not specific to acute pancreatitis. C: Grey Turner sign, bruising of the flanks, is associated with severe pancreatitis but does not necessarily indicate a seriously ill patient.

Correct Answer: D

Rationale: The correct answer is D: All of the above. Ultrasound in monitoring fetal growth can detect fetal anomalies by visualizing the fetus in real-time. It can also monitor placental health by assessing blood flow and position. Additionally, ultrasound can assess amniotic fluid levels to ensure proper fetal development. Therefore, all the benefits mentioned in choices A, B, and C are valid reasons why ultrasound is essential in monitoring fetal growth.

Correct Answer: C

Rationale: The correct answer is C: His blood pressure is likely a physiologic response to traumatic head injury. Rationale: 1. Physiologic response: Traumatic head injury can lead to autonomic dysregulation, causing increased sympathetic activity and elevated blood pressure to maintain cerebral perfusion. 2. Compensation mechanism: The body may increase blood pressure in response to hypotension to ensure vital organs receive adequate blood flow. 3. Treatment consideration: Understanding that elevated blood pressure can be a compensatory mechanism helps guide appropriate management strategies for traumatic head injury patients. Summary: A: Vasopressors can be used in traumatic head injury depending on the specific situation, and they are not always contraindicated. B: While hypotension can worsen outcomes in traumatic head injury, this choice overstates the risk without providing context. D: Identifying the cause of hypotension is crucial in managing traumatic head injury patients and should not be disregarded in favor of stabilizing the head injury.

Correct Answer: B

Rationale: The correct answer is B: Grunting on expiration. In respiratory distress syndrome, the infant may exhibit grunting on expiration due to the difficulty in maintaining lung inflation during exhalation. This is a compensatory mechanism to increase functional residual capacity. Grunting on inspiration (choice A) may be seen in other respiratory conditions. Flaring of the nostrils (choice C) is a sign of increased work of breathing but is not specific to respiratory distress syndrome. Neonatal tachycardia (choice D) can be a nonspecific sign of distress and is not a specific feature of respiratory distress syndrome.
