Nursing a Concept Based Approach Test Bank

Correct Answer: A

Rationale: Dilated cardiomyopathy is a condition characterized by an enlarged and weakened heart muscle, leading to decreased heart function. Common clinical manifestations of dilated cardiomyopathy include:

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.

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: C

Rationale: When teaching about the type of injury of an amputated digit, the nurse should include the proper handling of the amputated part. The correct method is to wrap the amputated digit in a clean towel, place it in a sealed plastic bag to prevent direct contact with ice, and then place the bag on ice. Placing the amputated digit directly on ice can cause frostbite and further damage to the tissue. By following this method, the amputated digit can be preserved properly until medical help is received. Transporting the person to the hospital is important but proper handling of the amputated digit is critical to increase the chances of successful reattachment. Placing the amputated digit in warm water or taping it to the hand are not recommended methods for preserving an amputated digit.

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.
