Nursing Elites

1. What behavior is essential for preventing in a child postoperatively after undergoing heart surgery to repair defects associated with tetralogy of Fallot?

• A. Crying
• B. Coughing
• C. Straining at stool
• D. Unnecessary movement

Correct answer: C

Rationale: Preventing straining at stool is crucial postoperatively after heart surgery for tetralogy of Fallot to avoid increasing intrathoracic pressure and placing stress on the surgical site. This can help prevent complications and promote faster healing. While crying, coughing, and unnecessary movement are common postoperative behaviors, they are not specifically linked to worsening outcomes in this context. Straining at stool is particularly emphasized due to its potential to impact the surgical site and overall recovery process.

2. A nurse is caring for an infant with phenylketonuria (PKU). What diet should the nurse anticipate will be ordered by the health care provider?

• A. Fat-free
• B. Protein-enriched
• C. Phenylalanine-free
• D. Low-phenylalanine

Correct answer: D

Rationale: A low-phenylalanine diet is required for infants with PKU to prevent the buildup of phenylalanine, which can lead to brain damage.

3. The nurse is developing a teaching plan for a child who is to have his cast removed. What instruction would the nurse most likely include?

• A. Applying petroleum jelly to the dry skin.
• B. Rubbing the skin vigorously to remove the dead skin.
• C. Soaking the area in warm water every day.
• D. Washing the skin with diluted peroxide and water.

Correct answer: C

Rationale: The correct instruction for the nurse to include in the teaching plan is to advise the child to soak the area in warm water every day. Soaking the area in warm water helps to gently remove dead skin without causing irritation, facilitating the safe and comfortable removal of the cast. Applying petroleum jelly (Choice A) may not be necessary and could interfere with the cast removal process. Rubbing the skin vigorously (Choice B) can lead to skin damage and should be avoided. Washing the skin with diluted peroxide and water (Choice D) is not recommended as peroxide can be irritating to the skin and may not aid in cast removal.

4. A nurse is reviewing the laboratory report of a child with tetralogy of Fallot that indicates an elevated RBC count. What does the nurse identify as the cause of the polycythemia?

• A. Low tissue oxygen needs
• B. Tissue oxygen needs
• C. Diminished iron levels
• D. Hypertrophic cardiac muscle

Correct answer: B

Rationale: The correct answer is B: Tissue oxygen needs. Polycythemia occurs in response to chronic hypoxia, leading the body to increase red blood cell production to enhance oxygen delivery. In tetralogy of Fallot, a congenital heart defect that results in reduced oxygen levels in the blood, the body compensates by producing more red blood cells. Choice A is incorrect as low tissue oxygen needs would not trigger polycythemia. Choice C, diminished iron levels, is not the cause of polycythemia in this case. Choice D, hypertrophic cardiac muscle, is unrelated to the pathophysiology of polycythemia in tetralogy of Fallot.

5. A 1-year-old child has a congenital cardiac malformation that causes right-to-left shunting of blood through the heart. What clinical finding should the healthcare provider expect?

• A. Proteinuria
• B. Peripheral edema
• C. Elevated hematocrit
• D. Absence of pedal pulses

Correct answer: C

Rationale: In a congenital cardiac malformation causing right-to-left shunting, the nurse should expect an elevated hematocrit. This occurs because the body compensates for decreased oxygenation by producing more red blood cells. Proteinuria (Choice A) is not typically associated with congenital cardiac malformations causing right-to-left shunting. Peripheral edema (Choice B) is more commonly seen in conditions causing left-sided heart failure. Absence of pedal pulses (Choice D) is not a typical finding in congenital cardiac malformations causing right-to-left shunting.
