Nursing Elites

1. The nurse is selecting a site to begin an intravenous infusion on a 2-year-old child. The superficial veins on his hand and arm are not readily visible. What intervention should increase the visibility of these veins?

• A. Gently tap over the site.
• B. Apply a cold compress to the site.
• C. Raise the extremity above the level of the body
• D. Use a rubber band as a tourniquet for 5 minutes.

Correct answer: A

Rationale: Gently tapping over the site helps dilate the veins and increase visibility. Applying a cold compress or raising the extremity above the body level constricts the veins, making them harder to access. Prolonged tourniquet use can cause discomfort and venous congestion.

2. What problem is most often associated with myelomeningocele?

• A. Biliary atresia
• B. Hydrocephalus
• C. Craniostenosis
• D. Tracheoesophageal fistula

Correct answer: B

Rationale: Hydrocephalus is the most commonly associated problem with myelomeningocele, present in 80% to 90% of affected children. Biliary atresia and tracheoesophageal fistula are not typically associated with myelomeningocele. Craniostenosis refers to the premature closing of cranial sutures and is not a common issue seen with myelomeningocele.

3. The nurse is assessing a child with type 2 diabetes. The child is awake and alert with a serum glucose of 60 mg/dL. What action should the nurse take?

• A. Administer Insulin.
• B. Administer Epinephrine.
• C. Give 15 grams of carbohydrates.
• D. Give glucagon by injection.

Correct answer: C

Rationale: For a conscious child with mild hypoglycemia, giving 15 grams of fast-acting carbohydrates is the appropriate intervention. This can quickly raise blood glucose levels to prevent further complications. Administering insulin (Choice A) would further lower the glucose level, which is not suitable in this scenario. Administering epinephrine (Choice B) is not indicated for hypoglycemia. Glucagon (Choice D) is used for severe hypoglycemia with altered consciousness, not for mild cases where the child is awake and alert.

4. What clinical manifestation(s) is associated with calcium depletion (hypocalcemia)?

• A. Nausea, vomiting
• B. Weakness, fatigue
• C. Muscle hypotonicity
• D. Neuromuscular irritability

Correct answer: D

Rationale: Hypocalcemia can lead to neuromuscular irritability, causing symptoms such as muscle cramps, tetany, or seizures. Other symptoms like nausea, vomiting, and weakness are less specific and can be related to various conditions.

5. What physiologic state(s) produces the clinical manifestations of nervous system stimulation and excitement, such as overexcitability, nervousness, and tetany?

• A. Metabolic acidosis
• B. Respiratory alkalosis
• C. Metabolic and respiratory acidosis
• D. Metabolic and respiratory alkalosis

Correct answer: D

Rationale: Both metabolic and respiratory alkalosis can cause overexcitability and nervous system stimulation due to a decrease in ionized calcium levels, which can cause symptoms such as tetany and paresthesias. Acidosis typically has the opposite effect, leading to depression of the nervous system.
