Correct Answer: D

Rationale: Tachycardia and nonspecific T-wave changes on the EKG are consistent with a pulmonary embolism (PE). Tachycardia is a common finding in PE, as the body tries to compensate for the decreased oxygenation due to the blockage in the pulmonary artery. Nonspecific T-wave changes, such as ST-segment abnormalities or inverted T-waves, can also be seen in patients with PE. These EKG findings, along with symptoms like dyspnea and chest pain, raise the suspicion for pulmonary embolism and warrant further diagnostic workup. Options A, B, and C are not specific findings related to a pulmonary embolism.

Correct Answer: A

Rationale: 1. A palpable thrill in the pulmonic area is a common finding in children with tetralogy of Fallot (TOF). This sensation is caused by turbulent blood flow across the pulmonic valve due to the structural abnormalities present in TOF.

Correct Answer: A

Rationale: For a client with coronary artery disease, physical rest is important to help decrease cardiac workload and sympathetic nervous system stimulation. Physical rest helps reduce the demand on the heart muscle, allowing the heart to work more efficiently. By minimizing physical activity, the client can prevent further strain on the heart and lower the risk of complications such as angina or heart attack. Additionally, reducing physical activity can help lower blood pressure and heart rate, which in turn decreases the workload on the heart. Thus, recommending physical rest is essential in managing and improving outcomes for clients with coronary artery disease.

Correct Answer: C

Rationale: The nurse is assessing the deep tendon reflexes of the patient to evaluate for signs of hyperthyroidism. In hyperthyroidism, there is an excessive production of thyroid hormones, which can lead to symptoms such as hyperactivity of the nervous system. Patients with hyperthyroidism may exhibit brisk deep tendon reflexes, along with other signs such as tremors, weight loss, heat intolerance, and tachycardia. Therefore, the nurse's assessment of deep tendon reflexes is particularly relevant in identifying signs of hyperthyroidism.

Correct Answer: C

Rationale: Disseminated intravascular coagulation (DIC) is a serious condition characterized by widespread clot formation in the small blood vessels, leading to bleeding tendencies. In DIC, the body consumes clotting factors and platelets faster than they can be replaced, resulting in both bleeding and clotting. Because of this complex pathophysiology, the first line treatment for DIC-related bleeding is to provide replacement of the consumed clotting factors and platelets. Fresh frozen plasma contains clotting factors, and platelets help in stopping bleeding by aiding in clot formation. Therefore, the administration of fresh frozen plasma and platelets helps to correct the coagulopathy in DIC and manage the bleeding episodes effectively. Aspirin, Warfarin (Coumadin), and Heparin are anticoagulants and would not be appropriate in the treatment of DIC-related bleeding as they can exacerbate the bleeding tendency in this condition.
