1. During an otoscopic examination on an infant, in which direction is the pinna pulled?

• A. Up and back
• B. Up and forward
• C. Down and back
• D. Down and forward

Correct answer: C

Rationale: For infants, the pinna is pulled down and back to straighten the ear canal and allow proper visualization of the tympanic membrane during otoscopic examination.

2. A four-year-old boy is admitted to the hospital with leg pain and fever. He is pale-looking and has bruises over various areas of his body. The physician suspects acute lymphoblastic leukemia (ALL). Which test would be used to confirm the diagnosis?

• A. Bone marrow aspirate
• B. Red blood cell count
• C. Lumbar puncture
• D. Bone scan

Correct answer: A

Rationale: A bone marrow aspirate is the definitive test to confirm acute lymphoblastic leukemia (ALL) in this case. It allows for the examination of leukemic cells in the bone marrow, providing a direct assessment of the disease. Red blood cell count (Choice B) is not specific for diagnosing leukemia but may show anemia commonly seen in leukemia patients. Lumbar puncture (Choice C) is used to assess central nervous system involvement, not primarily for confirming ALL. Bone scan (Choice D) is not a standard diagnostic test for ALL and is mainly used for evaluating bone metastases in other conditions.

3. What type of shock is characterized by a hypersensitivity reaction causing massive vasodilation and capillary leaks, which may occur with drug or latex allergy?

• A. Neurogenic shock
• B. Cardiogenic shock
• C. Hypovolemic shock
• D. Anaphylactic shock

Correct answer: D

Rationale: Anaphylactic shock is a severe allergic reaction that causes massive vasodilation and increased capillary permeability, leading to rapid fluid shifts and circulatory collapse if not treated promptly. Neurogenic, cardiogenic, and hypovolemic shocks have different etiologies.

4. A mother delivers an infant at 30 weeks gestation and asks if formula is better than breast milk since the baby is premature. What should the nurse respond?

• A. Human milk is preferred over other types of nutrition
• B. Human milk lacks essential nutrients for preterm infants
• C. Commercial infant formulas are preferred for preterm infants
• D. Commercial formulas have not been designed to meet preterm infants' needs

Correct answer: A

Rationale: Human milk is preferred, even for preterm infants, because it contains essential nutrients and antibodies that are particularly beneficial for their growth and development. Choice B is incorrect because human milk is rich in essential nutrients necessary for preterm infants. Choice C is incorrect as commercial infant formulas do not provide the same benefits as human milk. Choice D is incorrect as specialized formulas are available to meet the unique nutritional needs of preterm infants, but human milk remains the optimal choice.

5. A child is admitted in acute renal failure (ARF). Therapeutic management to rapidly provoke a flow of urine includes the administration of what medication?

• A. Propranolol (Inderal)
• B. Calcium gluconate
• C. Mannitol (Osmitrol) or furosemide (Lasix)
• D. Sodium, chloride, and potassium

Correct answer: C

Rationale: Mannitol and furosemide are diuretics commonly used to induce diuresis in acute renal failure, helping to provoke urine flow and manage fluid overload. Calcium gluconate and electrolyte supplementation are used for other specific conditions and not primarily for diuresis.
