Clinical diagnosis of polyhydramnios is based on an excessive amount of amniotic fluid exceeding

Correct Answer: D

Rationale: The correct answer is D: 3000 ml. Polyhydramnios is diagnosed when the amniotic fluid volume exceeds 2000 to 3000 ml. This is because amniotic fluid serves important functions in protecting the fetus and aiding in fetal movements. Having an excessively high volume can lead to complications such as preterm labor, fetal malpresentation, and placental abruption. Choices A, B, and C are incorrect as they do not fall within the range typically used to diagnose polyhydramnios. A: 1500 ml and C: 1900 ml are below the threshold, while B: 2500 ml is at the lower end but still not exceeding the diagnostic range for polyhydramnios.

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: Step 1: The presence of bile in vomitus suggests that the vomit originated from the small intestine or stomach, indicating an obstruction in the pyloric region. Step 2: Pyloric stenosis is a condition characterized by narrowing of the opening from the stomach to the small intestine, leading to projectile vomiting with bile. Step 3: Therefore, the presence of bile in vomitus suggests pyloric stenosis, making option D the correct answer. Summary: Option A is incorrect because vomiting preceding pain does not necessarily indicate a surgical abdomen. Option B is incorrect as the severity of symptoms is not solely based on age. Option C is incorrect as some surgical abdomens can present with vomiting as a primary symptom.

Correct Answer: A

Rationale: The correct answer is A: Six hours postnatally. Cephalohematoma is a collection of blood between a baby's skull and the periosteum. It typically appears several hours after birth due to trauma during delivery, causing bleeding under the periosteum. This allows time for the blood to accumulate and form a distinct swelling, making the onset around six hours postnatally. Choices B, C, and D are incorrect as they do not align with the typical timeline for the development of cephalohematoma.

Correct Answer: B

Rationale: Correct Answer: B (Managing as an outpatient case) Rationale: 1. Moderate pre-eclampsia indicates stable condition. 2. Outpatient management allows close monitoring without hospitalization. 3. Early intervention can prevent progression to severe pre-eclampsia. 4. Hospital admission is reserved for severe cases or complications (not moderate). 5. Encouraging fluids is important, but not the specific management for pre-eclampsia.

Correct Answer: B

Rationale: The correct answer is B: Within the first week of birth. Classical vitamin K deficiency bleeding typically occurs within the first week of birth due to low levels of vitamin K in newborns. During this time, infants are at a higher risk of bleeding complications if not supplemented with vitamin K. Choice A is incorrect because bleeding usually occurs after the first 24 hours. Choice C is incorrect as it does not specify a specific time frame within the neonatal stage. Choice D is incorrect as classical vitamin K deficiency bleeding is typically seen within the first week, not necessarily during the entire infancy stage.

Correct Answer: D

Rationale: Step 1: Campylobacter jejuni is a bacteria commonly associated with foodborne illness, often found in undercooked poultry and unpasteurized milk. Step 2: The patient's symptoms and microbiological findings are consistent with Campylobacter infection. Step 3: Advising the patient that there is no readily identified food source of this bacteria is important for preventing future exposure and potential reinfection. Step 4: Choices A, B, and C are incorrect as they do not address the specific educational need related to food safety and prevention of Campylobacter infection.

Correct Answer: D

Rationale: The correct answer is D: Escherichia coli. E. coli is the most common causative organism of pyelonephritis due to its prevalence in the gastrointestinal tract. It has specific virulence factors that enable it to ascend the urinary tract and cause infection. Streptococcus faecalis, Proteus vulgaris, and Staphylococcus pyogene are less commonly associated with pyelonephritis compared to E. coli.

Correct Answer: B

Rationale: The correct answer is B: Correct dehydration. Acute pyelonephritis can lead to dehydration due to fever, vomiting, and decreased fluid intake. High fluid intake helps correct dehydration by maintaining adequate fluid balance and preventing further complications. Increasing urine output (choice D) is a consequence of correcting dehydration. Promoting enough rest (choice A) is important but not the primary reason for advising high fluid intake. Relief of irritability (choice C) is not directly related to the management of acute pyelonephritis.
