Correct Answer: C

Rationale: The main source of nutrition for the baby during pregnancy is the placenta. The placenta is an organ that develops inside the uterus during pregnancy and provides essential nutrients and oxygen from the mother's blood to the baby through the umbilical cord. It acts as a barrier, protecting the baby from harmful substances while allowing necessary nutrients to pass through. The amniotic fluid serves as a protective cushion for the baby, the uterus provides the space for the baby to grow, and chorionic villi are small, hair-like structures on the placenta that aid in the exchange of nutrients and waste between the mother and the baby. However, the primary source of nutrition for the baby is the placenta, making option C the correct answer in this scenario.

Correct Answer: A

Rationale: The BEST position for a patient in shock is the modified Trendelenburg position. In this position, the patient's legs are elevated above the level of the heart to enhance blood flow back to the heart and vital organs. Placing the patient in the modified Trendelenburg position helps increase venous return, improves cardiac output, and promotes perfusion to vital organs, which can be crucial in managing shock. This position can help stabilize the patient's condition while awaiting further medical intervention.

Correct Answer: D

Rationale: Pemoline (Cylert) is a central nervous system stimulant used in the treatment of ADHD. One of the significant potential side effects of pemoline is hepatotoxicity, which can manifest as elevated liver function test results. Therefore, the nurse must monitor the patient's liver function regularly while they are taking pemoline to monitor for any signs of liver damage or dysfunction. It is essential to educate the patient about the signs and symptoms of liver problems, such as jaundice (yellowing of the skin or eyes), abdominal pain, nausea, or dark urine, and to report any such symptoms immediately to their healthcare provider. Regular monitoring and early detection of liver function abnormalities can help prevent severe liver damage in patients taking pemoline.

Correct Answer: A

Rationale: The appropriate approach of the nurse in this situation would be to talk about the reality of death with the father. It is important to provide appropriate and compassionate communication, acknowledging the father's grief while also gently guiding him towards accepting the reality of the situation. By discussing the reality of death and offering support, the nurse can help the father start the grieving process and eventually come to terms with the loss of his son. It is important to provide emotional support and guidance in a sensitive and respectful manner during such a difficult time.

Correct Answer: C

Rationale: The presence of persistent, severe perineal pain along with ecchymosis and swelling of the perineum can indicate a complication such as a hematoma. A hematoma is a collection of blood that can occur in the perineal area postpartum, usually as a result of trauma during delivery. It is essential to notify the healthcare provider immediately to assess the situation, provide appropriate treatment, and prevent further complications. Applying ice packs or administering additional analgesic medication may not address the underlying issue of a possible hematoma, so prompt medical evaluation is crucial in this situation.
