Correct Answer: B

Rationale: Thrombophlebitis, which is inflammation of a vein with the formation of a clot, is a contraindication to the use of oral contraceptives due to an increased risk of thromboembolism. Clients with a history of thrombophlebitis or thromboembolic disorders should avoid oral contraceptives to prevent further complications like deep vein thrombosis or pulmonary embolism.

Correct Answer: B

Rationale: In therapeutic groups, the focus is often on addressing specific issues or topics. This approach allows group members to concentrate on their concerns, share experiences, and work towards common goals. Autocratic structures, mandatory leadership by a licensed psychiatrist, or fostering dependent relationships are not typical characteristics of therapeutic groups.

Correct Answer: C

Rationale: Postterm pregnancy with oligohydramnios is a contraindication for the use of oxytocin due to the increased risk of uterine hyperstimulation and fetal distress. Oxytocin can further stress the fetus in this scenario, potentially leading to adverse outcomes. Therefore, it is crucial for the nurse to recognize this contraindication to ensure the safety of both the mother and the baby during labor.

Correct Answer: A

Rationale: Substernal retractions are a concerning sign of respiratory distress and can indicate acute chest syndrome, a severe complication of sickle-cell anemia. It results from vaso-occlusion in the pulmonary vasculature, leading to impaired oxygenation. Prompt reporting of this symptom is crucial for early intervention to prevent further complications. Hematuria, a high temperature, and sneezing are not specific manifestations of acute chest syndrome and would not warrant immediate notification to the provider in this context.

Correct Answer: A

Rationale: Placing the client's left arm on a pillow while sitting helps prevent shoulder displacement and assists in maintaining proper positioning and alignment. This intervention is crucial to prevent complications associated with immobility. Providing total care in ADLs may hinder the client's independence and recovery. Encouraging mobility is essential in preventing complications of immobility. Facilitating feeding by placing food on the unaffected side of the mouth helps reduce the risk of aspiration in clients with dysphagia.
