A nurse is preparing to give a client an infusion of packed red blood cells (PRBCS). The nurse is priming her administration IV tubing, the nurse primes one side of the Y tubing with the blood and the other should be which solution?
DSW
0.3% NS
Lactated Ringers
0.9% NS
The Correct Answer is D
A) D5W: Dextrose 5% in water (D5W) is not used with blood transfusions because it can cause hemolysis of the red blood cells due to its hypotonic nature. It can also potentially cause clumping and clotting.
B) 0.3% NS: This is a hypotonic saline solution, which can lead to hemolysis of red blood cells when used as a diluent for blood products. It is not appropriate for use in blood transfusions.
C) Lactated Ringers: Although lactated Ringer's solution is often used for fluid resuscitation, it contains calcium, which can cause clotting in the blood product. Therefore, it is not suitable for use with blood transfusions.
D) 0.9% NS: Normal saline (0.9% sodium chloride) is isotonic and the only solution recommended for use with blood transfusions. It does not cause hemolysis of red blood cells, does not alter the composition of the blood product, and helps to maintain the patency of the IV line. It is the standard diluent used in blood transfusions to ensure the safe administration of blood products.

Correct Answer is C
Explanation
A) The client is reporting constipation:
Constipation is a common issue with enteral feeding, often due to decreased fluid intake or lack of fiber. While it is important to manage constipation to improve comfort and bowel function, it is not as urgent as dealing with vomiting.
B) The client reports being thirsty:
Thirst can be a sign of dehydration or inadequate fluid intake. Although it should be addressed to ensure proper hydration, it is less critical compared to vomiting, which poses immediate risks.
C) The client is vomiting the enteral formula:
Vomiting is a priority concern because it can lead to aspiration, dehydration, electrolyte imbalances, and further complications. Addressing the cause of vomiting and managing it promptly is crucial for the client’s safety.
D) The client is experiencing abdominal cramping:
Abdominal cramping can be related to the feeding rate, type of formula, or intolerance. While it requires attention, it is less urgent than addressing vomiting, which could have more immediate and serious consequences.
Correct Answer is B
Explanation
A) Hyperactive bowel sounds: Hypercalcemia typically leads to decreased gastrointestinal motility, not increased. Clients with elevated calcium levels may experience constipation, abdominal pain, or ileus due to the relaxing effect of calcium on smooth muscle. Therefore, hyperactive bowel sounds are not a common finding in hypercalcemia.
B) Increased blood clots: Hypercalcemia can promote a hypercoagulable state, increasing the risk of thromboembolic events. This occurs because high calcium levels can enhance platelet aggregation and increase the coagulability of blood. Therefore, a client with elevated serum calcium may have an increased risk of developing blood clots.
C) Hyperactive deep tendon reflexes: Hypercalcemia generally leads to reduced neuromuscular excitability, which may manifest as decreased or absent deep tendon reflexes, muscle weakness, and lethargy. Hyperactive reflexes are more commonly associated with hypocalcemia, which causes increased neuromuscular excitability.
D) Positive Chvostek’s sign: Chvostek's sign is a clinical indicator of hypocalcemia, not hypercalcemia. It involves twitching of the facial muscles in response to tapping the facial nerve and is due to increased neuromuscular excitability caused by low calcium levels. Hypercalcemia, conversely, does not typically present with a positive Chvostek’s sign.
