Correct Answer: A

Rationale: The nurse would question the order for a D-dimer test in this case. A D-dimer test is a blood test used to help rule out or diagnose blood clots. However, in a child with a fractured femur complaining of sudden chest pain and difficulty breathing, the symptoms suggest the possibility of a pulmonary embolism (PE). In this scenario, a D-dimer test may not be necessary because the clinical presentation warrants more advanced imaging studies such as V/Q scans, CT pulmonary angiography, or MR pulmonary angiography to definitively diagnose or rule out a PE. Therefore, the focus should be on imaging studies rather than a D-dimer test in this situation.

Correct Answer: C

Rationale: Placental abruption is the separation of the placenta from the uterine wall before delivery. This condition is a significant risk factor for disseminated intravascular coagulation (DIC) because the sudden detachment can lead to massive internal bleeding. The release of large amounts of tissue factor from the placenta into the maternal circulation triggers widespread activation of the coagulation cascade, leading to the consumption of clotting factors and platelets. This uncontrolled activation of the clotting system can result in both excessive clot formation and bleeding, characteristic of DIC. Gestational diabetes, polyhydramnios, and placenta previa are not direct risk factors for DIC.

Correct Answer: C

Rationale: Sulfasalazine can cause photosensitivity, making the patient more prone to sunburn. Therefore, it is important for patients taking sulfasalazine to use sunscreen to protect their skin from harmful UV rays. This can help prevent sunburn and skin damage while on the medication. It is not necessary to take vitamin C with this drug, take it on an empty stomach, or limit fluid intake to 1500 mL per day.

Correct Answer: A

Rationale: Preeclampsia is a pregnancy complication characterized by high blood pressure and signs of damage to other organ systems, most often the liver and kidneys. Placental dysfunction is believed to be the main cause of preeclampsia. In a normal pregnancy, blood vessels in the placenta develop to supply the fetus with nutrients and oxygen. In preeclampsia, these blood vessels don't develop or function properly, leading to inadequate blood flow and reduced supply of nutrients to the placenta. This can result in high blood pressure and affect the function of other organs.
