Which gauge IV cannula should the nurse choose when preparing to initiate a blood transfusion?
- A. 18
- B. 24
- C. 22
- D. 28
Correct Answer: A
Rationale: An 18-gauge IV cannula is the most appropriate choice when preparing to initiate a blood transfusion. This larger size allows for the rapid administration of blood products, which is important to prevent clotting and ensure a stable flow of the transfusion. Smaller gauge sizes, such as 22, 24, or 28, may be too slow for transfusion purposes and could potentially lead to delays or complications during the procedure. Therefore, the optimal choice for initiating a blood transfusion is an 18-gauge IV cannula.

The procedure that has to be performed in order to shift thehigh pressure from the right ventricle to the left ventricle in Transposition of the Great Arteries (TGA) is:
- A. Rashkind Procedure
- B. Rastelli Procedure
- C. Pulmonary Artery Banding
- D. Jatene Procedure
Correct Answer: D
Rationale: The Jatene procedure is a surgical technique used to correct Transposition of the Great Arteries (TGA). In this procedure, the great arteries (aorta and pulmonary artery) are switched back to their correct positions. The aorta is connected to the left ventricle, and the pulmonary artery is connected to the right ventricle. This correction allows for oxygen-rich blood to flow from the left side of the heart to the body, and oxygen-poor blood to flow from the right side of the heart to the lungs for oxygenation. The Jatene procedure is preferred over other methods like the Rashkind procedure, Rastelli procedure, or pulmonary artery banding for this specific purpose of correcting the high-pressure circulation seen in TGA.
The nurse explains to a client that she will administer his first insulin dose in his abdomen. How does absorption at the abdominal site compare to absorption at other sites?
- A. Insulin is absorbed more slowly at abdominal injection sites than at other sites.
- B. Insulin absorbed rapidly regardless of the injection site.
- C. Insulin is absorbed more rapidly at abdominal injection than at other sites.
- D. Insulin is absorbed unpredictably at all injection sites.
Correct Answer: C
Rationale: Insulin absorption rates can vary depending on the injection site. The abdomen is one of the recommended sites for insulin injection due to its relatively rapid absorption rate compared to other sites such as the upper arm or thigh. Insulin injected into the abdomen is absorbed more quickly because of the larger blood supply in that area, leading to faster onset of action and better blood glucose control. This is why the nurse chose to administer the first insulin dose in the client's abdomen for optimal effectiveness.
An adolescent patient, who has pelvic inflammatory disease (PID), inquires about the effects of the disease on their ability to bear children. What is the pediatric nurse's best response?
- A. The occurrence of spontaneous abortion during pregnancy increases with PID.
- B. There is an increased risk for ectopic pregnancy or infertility.
- C. There is an increased risk of placenta previa.
- D. There should be no problems with your ability to conceive.
Correct Answer: B
Rationale: PID can lead to scarring of the fallopian tubes, increasing the risk of ectopic pregnancy or infertility.
About 500 children have just been exposed to radiation from a nuclear power plant accident. The most appropriate first step in your treatment of these children should be to
- A. prescribe potassium iodide to protect the thyroid
- B. order thyroid function tests
- C. order complete blood counts (CBCs)
- D. do nothing acutely; evaluate in 4-6 weeks
Correct Answer: A
Rationale: Potassium iodide can protect the thyroid from radioactive iodine exposure, which is a critical first step in radiation exposure.
Which is an effective strategy to reduce the stress of burn dressing procedures?
- A. Give the child as many choices as possible.
- B. Reassure the child that dressing changes are not painful.
- C. Explain to the child why analgesics cannot be used.
- D. Encourage the child to master stress with controlled passivity.
Correct Answer: A
Rationale: Giving the child as many choices as possible is an effective strategy to reduce the stress of burn dressing procedures. Allowing the child to have some control over the situation can help them feel more empowered and less anxious. By giving choices, such as letting the child choose the order in which things are done or the type of dressing used, the child is more likely to feel a sense of autonomy and reduced stress during the procedure. This approach can help the child cope better with the dressing changes and make the experience more manageable for them.
