Correct Answer: A

Rationale: A patient with a severe viral infection exhibiting reduced levels of circulating lymphocytes is likely due to the apoptosis of infected lymphocytes. When a virus enters the body, it can infect and replicate within lymphocytes, subsequently triggering the immune system to induce apoptosis in infected cells to prevent further spread of the virus. This process is part of the body's defense mechanism to control the viral infection. As a result, the circulating lymphocyte levels may decrease as infected lymphocytes are targeted for apoptosis. This phenomenon helps to limit viral replication and spread within the body, thereby aiding in the immune response to eliminate the virus.

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: Postpartum hemorrhage (PPH) is a significant complication after childbirth. The risk factors for PPH that are typically included in the list are uterine atony, overdistended uterus (e.g., multiple gestation or polyhydramnios), and ruptured uterus. Retroversion of the uterus is not a known risk factor for PPH. Retroversion refers to the position of the uterus, where it is tilted back towards the rectum. While retroverted uterus can sometimes lead to other issues or complications during pregnancy, it is not directly associated with an increased risk of postpartum hemorrhage.

Correct Answer: C

Rationale: The most likely causative agent in this scenario is Borrelia burgdorferi, which is the bacterium responsible for causing Lyme disease. The classic presentation of Lyme disease includes fever, malaise, and a skin lesion resembling a "bull's eye" rash, known as erythema migrans. This rash typically appears at the site of a tick bite. If left untreated, Lyme disease can progress to involve multiple organ systems and lead to more severe complications. Plasmodium falciparum is the causative agent of malaria, which typically presents with symptoms such as fever, chills, and fatigue, but it does not cause a "bull's eye" rash. Trypanosoma cruzi is the parasite responsible for Chagas disease, which presents with symptoms such as fever, swelling at the site of entry (typically the bite wound), and enlarged lymph nodes, but it does not

Correct Answer: A

Rationale: When a baby is placed on phototherapy, especially for treating jaundice, it is crucial for the nurses to put sunglasses on the newborn to protect their eyes. Phototherapy involves exposing the baby's skin to certain types of light to help break down the bilirubin causing the jaundice. However, this light can be harmful to the baby's sensitive eyes, potentially leading to eye damage or other eye-related issues if not protected adequately. Therefore, placing sunglasses on the newborn is a necessary precaution to ensure the safety and well-being of the baby's eyes during the treatment.
