Correct Answer: C

Rationale: The considered ideal fetal position for a healthy delivery is left transverse anterior with moderate flexion. This position allows for an easier descent through the birth canal and reduces the chances of complications during delivery. This position is optimal for a smoother and safer delivery process for both the mother and the baby.

Correct Answer: D

Rationale: A trimalleolar fracture is characterized by fractures involving the lateral malleolus (distal fibula), medial malleolus (distal tibia), and the posterior tubercle of the distal tibia. This fracture pattern results in instability of the ankle joint and is often associated with widening of the ankle mortise on X-ray. The deformity and swelling seen in this patient are indicative of a trimalleolar fracture and are typically caused by a high-energy injury, such as a forceful twisting motion. Treatment for trimalleolar fractures often involves surgical intervention to stabilize the ankle joint and restore normal function.

Correct Answer: D

Rationale: Incompetent cervix refers to a weakened cervix that is unable to support the weight of the growing fetus, leading to painless cervical dilation and second-trimester pregnancy loss. In this condition, the cervix may dilate prematurely without contractions, resulting in a painless cervical dilation. The history of recurrent second-trimester losses, along with cervical dilation and absence of uterine contractions in the presenting pregnant woman, are characteristic of incompetent cervix. Prompt recognition and management with cerclage placement can help prevent further pregnancy losses in women with incompetent cervix.

Correct Answer: C

Rationale: Cryptosporidium parvum is a protozoan parasite that commonly causes waterborne illness characterized by watery diarrhea, abdominal cramps, and nausea. This parasite is often transmitted through contaminated water sources such as streams or lakes. Laboratory tests identifying oocysts in the stool sample are indicative of Cryptosporidium infection. Giardia lamblia can also cause similar symptoms, but the presence of oocysts points more towards Cryptosporidium in this case. Entamoeba histolytica causes amoebic dysentery with bloody diarrhea and is usually associated with fecal-oral transmission through contaminated food or water. Cyclospora cayetanensis typically causes prolonged watery diarrhea and is associated with the ingestion of contaminated food or water.

Correct Answer: A

Rationale: A retrospective audit involves reviewing past cases or data to evaluate processes, outcomes, or compliance with standards. In this scenario, the nursing team plans to audit post-op patients who developed pressure sores over the past year at the Orthopedic unit. By looking at historical data from the past year, the audit is considered retrospective as it assesses what has occurred over a specified period. This type of audit helps identify trends, patterns, and areas for improvement based on past events.
