Correct Answer: B

Rationale: The correct answer is B because nurse-initiated interventions involve autonomous actions based on clinical judgment to achieve client outcomes. Nurses assess, plan, and implement care independently. Choice A involves physician orders, not nurse-initiated actions. Choice C relates to medical treatment, not nursing interventions. Choice D focuses on collaboration with other providers, not solely nurse-initiated actions. In summary, only choice B aligns with the independent and outcome-focused nature of nurse-initiated interventions.

Correct Answer: B

Rationale: The correct answer is B: Redness of the upper part of the feet. During lymphangiography, a contrast dye is injected into the lymphatic vessels. This may cause temporary redness in the upper part of the feet due to the dye spreading throughout the lymphatic system. Purplish stools (A), bluish urine (C), and coldness of the soles (D) are not expected side effects of lymphangiography and do not have a direct correlation with the procedure.

Correct Answer: A

Rationale: Step 1: Pulmonary edema is caused by fluid accumulation in the lungs due to increased pressure in the pulmonary vasculature. Step 2: Decreased left ventricular pumping leads to congestive heart failure, causing increased pressure in pulmonary circulation. Step 3: This increased pressure forces fluid from the capillaries into the alveoli, causing pulmonary edema. Step 4: Increased left atrial contractility (B) would not directly lead to pulmonary edema. Step 5: Decreased right ventricular elasticity (C) and increased right atrial pressure (D) are not directly related to the pathophysiology of pulmonary edema. Summary: The correct answer is A because decreased left ventricular pumping directly contributes to the increased pressure in the pulmonary circulation that leads to pulmonary edema. Choices B, C, and D do not align with the primary underlying disorder of pulmonary edema.

Correct Answer: A

Rationale: The correct answer is A: Type I (immediate, anaphylactic) hypersensitivity reaction. In this scenario, the client experiences symptoms shortly after the transfusion starts, such as chest pain, nausea, itching, urticaria, tachycardia, and hypotension, which are indicative of an immediate hypersensitivity reaction. Type I reactions involve the release of histamine and other inflammatory mediators from mast cells and basophils, leading to the symptoms described. The nurse's prompt action of stopping the transfusion and notifying the physician aligns with managing this type of reaction. Incorrect choices: B: Type II (cytolytic, cytotoxic) hypersensitivity reaction - This type of reaction involves antibodies targeting specific cells, leading to their destruction. The symptoms described in the scenario are not consistent with this type of reaction. C: Type III (immune complex) hypersensitivity reaction - This type of reaction involves the formation of immune complexes that deposit in tissues, causing
