A nurse is caring for a client who has an implanted venous access port.

Which of the following should the nurse use to access the port?

Choice A reason

Setting the IV infusion pump to administer the blood over 6 hours is not the recommended rate for administering packed RBCs. Blood transfusions are typically given more rapidly, usually within 2 to 4 hours. The specific rate may vary depending on the client's condition and the provider's order.

Choice B reason

Administering the blood via a 21-gauge IV needle is not typically related to the administration of the packed RBCs. The appropriate gauge of the IV needle for blood transfusions depends on the client's condition and the type of transfusion. Larger-gauge needles are often used for blood transfusions to allow for a faster flow rate and prevent haemolysis of the blood cells.

Choice C reason

Checking the client's vital signs from the previous shift prior to the initiation of the transfusion is not sufficient for ensuring the client's safety during the blood transfusion. The nurse should assess the client's current vital signs, including temperature, heart rate, blood pressure, and respiratory rate, before initiating the transfusion. Monitoring vital signs is essential during the transfusion to detect any adverse reactions or changes in the client's condition.

Choice D reason

Rush the blood administration tubing with 0.9% sodium chloride prior to the transfusion is the correct answer. When preparing to administer a blood transfusion to an adult client with chronic anaemia, the nurse should rush the blood administration tubing with 0.9% sodium chloride (normal saline) prior to the transfusion. This process is called priming the tubing.

Priming the tubing helps remove any residual air from the tubing and ensures that the blood transfusion is administered smoothly without introducing air into the client's bloodstream. Air embolisms can be a serious complication, and priming the tubing with normal saline helps prevent this risk.

This is because coarctation of the aorta is a congenital condition where the aorta is narrow, usually in the area where the ductus arteriosus inserts. This causes a decrease in blood flow to the lower body, resulting in weak or absent pulses in the femoral arteries.

The other choices are incorrect for the following reasons:

• Choice A, frequent nosebleeds, is not a typical sign of coarctation of the aorta.

Nosebleeds can be caused by many factors, such as dry air, allergies, trauma, or bleeding disorders.

• Choice B, upper extremity hypotension, is also not a common finding in coarctation of the aorta. In fact, patients with this condition may have high blood pressure in the upper extremities due to the increased resistance of the narrowed aorta.
• Choice D, increased intracranial pressure, is not directly related to coarctation of the aorta.

Increased intracranial pressure can be caused by various conditions that affect the brain, such as head injury, stroke, infection, or tumor.

Normal ranges for blood pressure and pulse vary depending on age, sex, and health status.

However, some general guidelines are:

• Blood pressure: less than 120/80 mmHg for adults; less than 95/65 mmHg for infants.
• Pulse: 60 to 100 beats per minute for adults; 100 to 160 beats per minute for infants.
