Correct Answer: A

Rationale: The correct answer is A because cord presentation occurs when the umbilical cord lies in front of the presenting part after the membranes have ruptured. This can lead to compression of the cord during labor, affecting fetal oxygenation. Option B is incorrect as it describes cord prolapse, where the cord lies in front of the presenting part before membrane rupture. Option C describes nuchal cord, where the cord is wrapped around the fetal neck. Option D describes cord abruption, where the cord detaches prematurely from the placenta.

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: 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: A

Rationale: The correct answer is A: A temperature of 101.5°F. A fever indicates an inflammatory response, which could be due to a complication like cholecystitis or cholangitis. Elevated leukocyte count (choice B) supports infection but is not as specific as a fever. Palpable gallbladder (choice C) may suggest inflammation but not necessarily a complication. A positive Murphy's sign (choice D) is indicative of gallbladder inflammation but does not directly indicate a complication requiring surgical evaluation.

Correct Answer: D

Rationale: The correct answer is D: Check the neonate’s vital signs every 2-4 hourly. This is the priority action because neonates undergoing phototherapy are at risk for dehydration and temperature instability. Monitoring vital signs regularly helps to detect any signs of dehydration, such as decreased urine output or increased heart rate, and ensures timely intervention. Explanation for other choices: A: Turning the neonate every six hours routinely is important for preventing pressure ulcers but is not the priority when compared to monitoring vital signs for potential complications. B: Encouraging the mother to discontinue breastfeeding is incorrect as breastmilk provides essential nutrients and hydration, which are important for neonates, even during phototherapy. C: Notifying the physician if the skin turns bronze-colored is important to address a potential adverse reaction to phototherapy but does not take precedence over monitoring vital signs for immediate concerns.
