A nurse is caring for a child who has cystic fibrosis and requires postural drainage.

Which of the following actions should the nurse take?

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.

These are signs of severe dehydration in an infant, which can be life-threatening and should be reported to the provider immediately. The infant may need intravenous fluids and electrolytes to restore hydration and prevent complications.

Choice B is wrong because a temperature of 38° C (100.4° F) and pulse rate of 124/min are not abnormal for an infant and do not indicate severe dehydration. These are common findings in an infant who has gastroenteritis, which is an inflammation of the stomach and intestines caused by a virus, bacteria, or parasite.

Choice C is wrong because decreased appetite and irritability are also common findings in an infant who has gastroenteritis, but they do not indicate severe dehydration. The nurse should encourage oral rehydration with fluids such as breast milk, formula, or oral electrolyte solution.

Choice D is wrong because pale skin and a 24-hr fluid deficit of 30 mL are not signs of severe dehydration in an infant.

A fluid deficit of 30 mL is less than 1 oz and is not significant for an infant who weighs about 10 kg (22 lbs). A fluid deficit of more than 10% of body weight would indicate severe dehydration.

Normal ranges for vital signs in infants are as follows:

• Temperature: 36.5° C to 37.5° C (97.7° F to 99.5° F)
• Pulse rate: 100 to 160/min
• Respiratory rate: 30 to 60/min
• Blood pressure: 65/41 to 100/50 mm Hg

Normal ranges for fluid intake and output in infants are as follows:

• Fluid intake: 100 to 150 mL/kg/day
• Fluid output: 1 to 2 mL/kg/hr
