A nurse is planning teaching for a client who has a new diagnosis of HIV. Which of the following information should the nurse include about preventing the spread of the infection?

A. Prime the tubing with 0.9% sodium chloride: Blood products must be administered with 0.9% sodium chloride to prevent hemolysis. Priming the tubing with saline ensures compatibility and maintains patency, allowing safe and effective transfusion without compromising the integrity of red blood cells.

B. Attach a single-line administration set: Blood transfusions require a specialized Y-type or filtered tubing to reduce the risk of clots, debris, and air embolism. Using a single-line set without a filter could allow microaggregates to enter the circulation.

C. Use tubing that does not have a filter in the drip chamber: A filter is essential for removing clots, debris, and cellular aggregates from the blood product. Administering blood without a filter increases the risk of complications such as emboli and febrile reactions.

D. Use an IV catheter that is at least 24-gauge: A 24-gauge catheter is too small for safe transfusion of blood products. A larger-bore catheter, typically 18–20 gauge, is recommended to allow adequate flow and prevent hemolysis or catheter rupture during transfusion.

A. Muffled heart sounds: Muffled or distant heart sounds occur due to accumulation of fluid in the pericardial sac, which dampens the transmission of heart sounds. This is an early and classic manifestation of cardiac tamponade, reflecting impaired ventricular filling and reduced stroke volume. Prompt recognition is critical to prevent hemodynamic compromise.

B. Decreased jugular vein distention: Cardiac tamponade typically causes increased jugular vein distention due to impaired right atrial filling and elevated central venous pressure. A decrease in jugular venous distention would be inconsistent with this condition.

C. Widening pulse pressure: Cardiac tamponade usually produces a narrowing pulse pressure due to reduced stroke volume and systolic pressure, rather than widening. A widened pulse pressure is more characteristic of conditions like aortic regurgitation.

D. Coarse lung sounds: Coarse lung sounds are associated with pulmonary edema or fluid in the alveoli, not with pericardial tamponade. Lung sounds are often normal in early tamponade unless concurrent pulmonary complications are present.
