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: C

Rationale: For a client with peripheral vascular disease (PVD), the nurse would recommend low-impact exercises that promote circulation and improve overall health without overstressing the cardiovascular system. Yoga is a beneficial form of exercise for individuals with PVD because it involves gentle movements, controlled breathing, and mindfulness practices that can help improve flexibility, strength, and blood flow. Additionally, yoga can help reduce stress and improve relaxation, which can be beneficial for managing symptoms associated with PVD. Weight lifting and team sports may be too strenuous for individuals with PVD, and passive ROM exercises may not provide the cardiovascular benefits needed for this condition.

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: Activity intolerance is the most appropriate nursing diagnosis for a client with cardiomyopathy who becomes short of breath with ambulation and eating and fatigued with routine care activities. Cardiomyopathy is a condition where the heart muscle becomes weakened, affecting its ability to pump blood effectively. As a result, the client may experience symptoms such as shortness of breath, fatigue, and decreased tolerance for physical activity. By identifying activity intolerance as a nursing diagnosis, the nurse can focus on addressing the client's limitations in performing activities and developing a plan of care to help improve the client's endurance and functional ability.

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.
