Correct Answer: A

Rationale: The correct answer is A: Monitor vital signs and check for allergic reactions. When administering blood products, monitoring vital signs such as blood pressure, heart rate, and temperature is crucial to detect any adverse reactions promptly. Checking for allergic reactions, such as hives, itching, or difficulty breathing, is essential to ensure patient safety. Choice B is incorrect because verifying blood type and compatibility is typically done by the laboratory before the blood is issued for transfusion. Choice C is not a direct nursing consideration during the administration of blood products. While monitoring for signs of infection and sepsis is important in general patient care, it is not specific to blood transfusions. Choice D is also incorrect as ensuring consent is signed and preparing for possible reactions are important but do not directly relate to the immediate nursing considerations during blood product administration.

Correct Answer: C

Rationale: In the early stages of hypovolemic shock, the body initiates compensatory mechanisms to maintain perfusion. One of these mechanisms is an increased respiratory rate to improve oxygen delivery. This helps to offset the decreased circulating blood volume. A heart rate of 60/min (choice A) is not expected in hypovolemic shock; instead, tachycardia is a common finding due to the body's attempt to maintain cardiac output. Increased urinary output (choice B) is not typically seen in hypovolemic shock as the body tries to conserve fluid. Hypothermia (choice D) is usually a late sign of shock when the body's compensatory mechanisms are failing, and perfusion is severely compromised.

Correct Answer: B

Rationale: The priority for a client with dehydration is to monitor electrolyte levels to prevent imbalances. Dehydration can lead to electrolyte disturbances, which can have serious consequences. Administering antiemetics (Choice A) may help with nausea but does not address the root cause of dehydration. Administering oral rehydration solutions (Choice C) can be beneficial, but monitoring electrolyte levels is crucial in managing dehydration. Administering intravenous fluids (Choice D) is important in severe cases of dehydration, but monitoring electrolytes should come first to assess the extent of the imbalance and guide fluid replacement therapy effectively.

Correct Answer: C

Rationale: A prothrombin time (PT) of 12 seconds is below the therapeutic range for warfarin and indicates a need for dosage adjustment. The correct answer is C. A normal International normalized ratio (INR) for a client on warfarin therapy is usually between 2.0 to 3.0; therefore, an INR of 2.5 is within the expected range. A platelet count of 180,000/mm³ is within the normal range (150,000 to 450,000/mm³) and does not require immediate reporting. A partial thromboplastin time (PTT) of 30 seconds is also within the normal range (25-35 seconds) and does not indicate a need for urgent action.
