Correct method of mouth to mouth respiration is that the victim's chin is held:
- A. Forward
- B. Backward
- C. Sideward
- D. Downward
Correct Answer: D
Rationale: When performing the correct method of mouth-to-mouth respiration, it is essential to ensure that the victim's chin is held downward. This helps to properly open the airway, allowing for effective ventilation. By tilting the head back and holding the chin downward, you are able to align the victim's airway to allow the entry of air into the lungs during rescue breathing. Holding the chin in a downward position also helps prevent any obstruction that may hinder the flow of air. Remember to also pinch the victim's nose closed while giving breaths to ensure that the air goes into their lungs.

Which is an important nursing consideration when chest tubes will be removed from a child?
- A. Explain that it is not painful.
- B. Explain that only a Band-Aid will be needed.
- C. Administer analgesics before the procedure.
- D. Expect bright red drainage for several hours after removal.
Correct Answer: C
Rationale: Administering analgesics before removing chest tubes from a child is an important nursing consideration because the procedure may cause pain or discomfort. While it is ideal to minimize pain during and after the removal, it is essential to anticipate the possibility of discomfort and provide appropriate pain management to ensure the child's comfort and well-being. By administering analgesics before the procedure, nurses can help alleviate any potential pain and promote a more positive experience for the child.
Which of the following conditions is suspected?
- A. Anemia
- B. Rheumatic arthritis
- C. Leukemia
- D. Systematic Lupus Erythematosus (SLE)
Correct Answer: C
Rationale: Leukemia is a type of cancer that affects the blood and bone marrow, leading to an overproduction of abnormal white blood cells. The symptoms of leukemia can include fatigue, weakness, weight loss, frequent infections, fever, bruising or bleeding easily, and bone pain. Given the vague presenting symptoms and the potential involvement of multiple bodily systems, leukemia is a condition that should be suspected and investigated further. Anemia, rheumatic arthritis, and systematic lupus erythematosus can also present with some similar symptoms, but for the given scenario, leukemia is the most probable condition to suspect.
Which of the following is MOST likely considered a risk factor for extraneural metastasis in primary brain tumors?
- A. age less than 10 year
- B. female gender
- C. ventriculoperitoneal (VP) shunt insertion
- D. supratentorial tumor
Correct Answer: A
Rationale: Younger age is a significant risk factor for extraneural metastasis in pediatric brain tumors.
When palpating the brachial, radial, and femoral pulses of a neonate, the nurse notes a difference in pulse amplitude between the femoral and radial pulses bilaterally. This difference suggests:
- A. Patent ductus arteriosus
- B. Coarctation of the aorta
- C. Diminished cardiac output
- D. Left to right shunting in the heart. 104 Practice Exam I
Correct Answer: B
Rationale: Coarctation of the aorta is a congenital heart defect in which there is a narrowing of the aorta leading to differential pulses in the upper and lower extremities. In neonates, this can manifest as weaker femoral pulses compared to radial pulses due to decreased blood flow to the lower body. This difference in pulse amplitude between the femoral and radial pulses bilaterally is a classic finding in coarctation of the aorta, making it the most likely cause in this scenario. Other conditions like patent ductus arteriosus, diminished cardiac output, or left to right shunting in the heart may not specifically present with this particular pulse amplitude difference.
Which chromosomal abnormality is often characteristic of infantile ALL?
- A. t(4;11)
- B. t(12;21)
- C. t(9;22)
- D. t(1;19)
Correct Answer: A
Rationale: The t(4;11) translocation is commonly found in infantile ALL and is associated with a poor prognosis.
