Nursing Elites

1. A healthcare provider is assessing a child with acute lymphocytic leukemia. Which of the following findings is the priority for the healthcare provider to report?

• A. Bruising
• B. Petechiae
• C. Elevated WBC count
• D. Elevated platelet count

Correct answer: B

Rationale: The priority finding to report for a child with acute lymphocytic leukemia is petechiae. Petechiae indicate a low platelet count, which increases the risk of bleeding. Therefore, the healthcare provider should promptly report petechiae to initiate appropriate interventions to prevent bleeding complications.

2. The renin-angiotensin-aldosterone system plays an important role in maintaining blood pressure. Which compound in this system is most powerful at raising blood pressure?

• A. Angiotensin I
• B. Angiotensin II
• C. Angiotensin III
• D. Renin

Correct answer: B

Rationale: Angiotensin II is the most potent compound in the renin-angiotensin-aldosterone system for raising blood pressure. It acts as a powerful vasoconstrictor, leading to increased systemic vascular resistance. Angiotensin II is formed from angiotensin I through the action of the angiotensin-converting enzyme. While renin initiates the cascade by converting angiotensinogen to angiotensin I, it is angiotensin II that exerts the strongest pressor effect.

3. A neonate with a meningomyelocele is scheduled for surgery in the morning. Which nursing action is appropriate for this neonate?

• A. Applying a diaper to prevent contamination of the sac
• B. Positioning the newborn in a side-lying position
• C. Encouraging the mother to hold the newborn because she will not be able to pick him up after surgery
• D. Positioning the newborn in a prone position

Correct answer: D

Rationale: Positioning the newborn in a prone position is appropriate for a neonate with a meningomyelocele before surgery. Placing the newborn in this position helps prevent pressure on the sac, reducing the risk of damaging it and promoting optimal surgical outcomes. Applying a diaper (choice A) may not be recommended as it can increase pressure on the sac. Positioning the newborn in a side-lying position (choice B) or encouraging the mother to hold the newborn (choice C) are not ideal actions before surgery as they do not address the specific needs of a neonate with a meningomyelocele.

4. A healthcare professional is reviewing the laboratory report of an infant who is receiving treatment for severe dehydration. The professional should identify which of the following laboratory values indicates effectiveness of the current treatment?

• A. Potassium 2.9 mEq/L
• B. Sodium 140 mEq/L
• C. Urine specific gravity 1.035
• D. BUN 25 mg/dL

Correct answer: B

Rationale: A sodium level of 140 mEq/L within the expected reference range indicates effective treatment for dehydration. In dehydration, sodium levels are often elevated, so a normal sodium level suggests that the treatment is helping to restore the electrolyte balance in the infant's body.

5. While caring for four different pediatric clients, which child is at the highest risk for dehydration?

• A. 7-year-old child with migraine headaches
• B. 4-year-old child with a broken arm
• C. 2-year-old child with cellulitis of the left leg
• D. 18-month-old child with tachypnea

Correct answer: D

Rationale: The 18-month-old child with tachypnea is at the highest risk for dehydration due to increased insensible water loss associated with rapid breathing.
