Nursing Elites

1. When speaking to young parents, the nurse states that lead poisoning is one of the most common preventable health problems affecting children. What condition occurs when the level of lead ingested exceeds the amount that can be absorbed by the bone?

• A. Malnutrition
• B. Anemia
• C. Bone pain
• D. Diarrhea

Correct answer: B

Rationale: The correct answer is B: Anemia. When the amount of lead ingested exceeds the amount that can be absorbed by the bone, it leads to anemia. Malnutrition (Choice A) is a state of inadequate nutrition, not directly related to lead poisoning. Bone pain (Choice C) is a symptom of lead poisoning due to its effects on bones but not directly related to lead ingestion exceeding absorption. Diarrhea (Choice D) is not a direct consequence of lead ingestion exceeding absorption by bones.

2. The parents of a child suffering from depression ask the nurse what causes depression in children. Which answer is an appropriate response by the nurse?

• A. The causes of major depression are unknown.
• B. Major affective disorders in parents increase depression in children.
• C. Boys are more likely than girls to be depressed.
• D. The prevalence rate is higher in prepubescent children.

Correct answer: B

Rationale: The correct answer is B because while the exact causes of depression in children are not fully understood, research indicates that children are more likely to experience depression if their parents have a major affective disorder. Choice A is incorrect because it suggests that the causes of major depression are entirely unknown, which is not accurate. Choice C is incorrect as there is no conclusive evidence that boys are more likely than girls to be depressed. Choice D is incorrect as the prevalence rate of depression is not necessarily higher in prepubescent children specifically.

3. When performing an assessment of a child with recurrent abdominal pain (RAP), what symptom is the child most likely to experience?

• A. Increased temperature
• B. Constipation
• C. Right quadrant pain
• D. Exercise-associated pain

Correct answer: B

Rationale: When assessing a child with recurrent abdominal pain (RAP), constipation is a common symptom. Children with RAP often experience periumbilical pain that is unrelated to eating, defecation, or exercise. While increased temperature, right quadrant pain, and exercise-associated pain can occur in various conditions, they are not typically associated with RAP in children.

4. Laboratory findings indicate that a client’s serum potassium level is 2.5 mEq/L. What action should the nurse take?

• A. Administer potassium supplements orally.
• B. Increase the client's dietary potassium intake.
• C. Inform the healthcare provider of the need for potassium replacement.
• D. Monitor the client's ECG continuously.

Correct answer: C

Rationale: A serum potassium level of 2.5 mEq/L is critically low, indicating severe hypokalemia. In this situation, it is essential for the nurse to inform the healthcare provider promptly about the need for potassium replacement. Administering potassium supplements orally or increasing dietary potassium intake is not appropriate in cases of critically low potassium levels as immediate and precise replacement is necessary. Monitoring the client's ECG continuously is important in severe cases of hypokalemia, but the priority action should be to inform the healthcare provider for further management and treatment.

5. Ten hours following thrombolysis for an ST elevation myocardial infarction (STEMI), a client is receiving a lidocaine infusion for isolated runs of ventricular tachycardia. Which finding should the nurse document in the EMR as a therapeutic response to the lidocaine infusion?

• A. Stabilization of BP ranges
• B. Cessation of chest pain
• C. Reduced heart rate
• D. Decreased frequency of episodes of VT

Correct answer: D

Rationale: The correct answer is D. Decreased frequency of ventricular tachycardia (VT) episodes indicates that the lidocaine infusion is effectively managing the ventricular tachycardia. Stabilization of BP ranges (choice A) may not directly correlate with the therapeutic response to lidocaine for VT. Cessation of chest pain (choice B) may indicate pain relief but does not specifically address the effectiveness of lidocaine for VT. Reduced heart rate (choice C) is not a direct indicator of the response to lidocaine for managing VT.
