Correct Answer: B

Rationale: The correct answer is B: Hemorrhage. The nurse manager would intervene because hemorrhage is a life-threatening condition requiring immediate attention. Wandering (A), urinary retention (C), and impaired swallowing (D) are important assessments but do not pose the same level of immediate risk as hemorrhage. The nurse manager would prioritize addressing the hemorrhage to ensure the patient's safety and well-being.

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: C

Rationale: The correct answer is C: Pernicious anemia. Vitamin B12 is essential for the production of red blood cells, and its deficiency can lead to pernicious anemia, characterized by decreased red blood cell production. Without adequate vitamin B12, the body cannot properly utilize iron, leading to anemia. Iron deficiency anemia (choice A) is a result of insufficient iron levels, not vitamin B12 deficiency. Sickle cell anemia (choice B) is a genetic disorder affecting hemoglobin, not related to vitamin B12 deficiency. Acquired haemolytic anemia (choice D) is caused by the premature destruction of red blood cells, not by vitamin B12 deficiency.

Correct Answer: A

Rationale: The correct answer is A because monitoring the client's temperature before, during, and after the transfusion allows the nurse to identify any changes or trends that may indicate a complication related to the blood transfusion. This comprehensive monitoring helps differentiate between a normal body response to cold blood infusion and a potential adverse reaction. Choice B is incorrect because documenting the client's temperature only after the transfusion may miss important changes during the process. Choice C is incorrect as the temperature of the blood before transfusion does not directly indicate the client's response to the chilled blood. Choice D is incorrect as comparing the client's temperature with the temperature of the blood alone does not provide a complete picture of the client's condition throughout the transfusion process.

Correct Answer: A

Rationale: The correct answer is A: Hearing loss, vertigo, and tinnitus. Meniere's disease is characterized by a triad of symptoms: recurrent episodes of vertigo, sensorineural hearing loss, and tinnitus. Vertigo is a spinning sensation, hearing loss affects the inner ear, and tinnitus is ringing in the ear. Nausea, vomiting, pain, nystagmus, or headache are not typically part of the classic triad of Meniere's disease symptoms. Therefore, option A is the most appropriate choice based on the specific symptomatology associated with Meniere's disease.
