Nursing Elites

1. What is the goal of pharmacologic therapy in the treatment of Parkinson�s disease?

• A. To increase the amount of acetylcholine at the pre-synaptic neurons
• B. To reduce the amount of dopamine available in the substantia nigra
• C. To balance cholinergic and dopaminergic activity in the brain
• D. To block dopamine receptors in pre-synaptic and post-synaptic neurons

Correct answer: C

Rationale: Parkinson�s disease results from a decrease in dopaminergic (inhibitory) activity, leaving an imbalance with too much cholinergic (excitatory) activity. With an increase in dopamine, the neurotransmitter activity becomes more balanced, and symptoms are controlled.

2. A child with croup has an increased PCO2, a decreased pH, and a normal HCO3 blood gas value. Which finding does the nurse report to the healthcare provider based on these data?

• A. Uncompensated metabolic alkalosis
• B. Uncompensated metabolic acidosis
• C. Uncompensated respiratory acidosis
• D. Uncompensated respiratory alkalosis

Correct answer: C

Rationale: The blood gas values indicate uncompensated respiratory acidosis. In respiratory acidosis, there is an increased PCO2, decreased pH, and a normal HCO3 level. This condition requires immediate attention to address the underlying respiratory problem causing the acidosis.

3. The nurse is unsuccessful in inserting a nasogastric tube for a newborn client. The nurse suspects the newborn has esophageal atresia/tracheoesophageal (EA/TE) fistula. Which nursing action is appropriate while waiting for the healthcare provider to further assess the neonate?

• A. Position the newborn in a semi-Fowler position.
• B. Allow the newborn to stay in the nursery for observation.
• C. Offer the newborn pacifier for comfort.
• D. Wrap the newborn in blankets and place in an incubator.

Correct answer: A

Rationale: Positioning the newborn in a semi-Fowler position is appropriate as it helps prevent aspiration in suspected EA/TE fistula. This position helps reduce the risk of regurgitation and aspiration of gastric contents. Placing the newborn in a semi-Fowler position promotes the drainage of secretions and reduces the risk of complications while awaiting further assessment by the healthcare provider.

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. The healthcare provider is providing dietary teaching to the parent of a school-age child who has celiac disease. The healthcare provider should recommend that the parent offer which of the following foods to the child?

• A. Wheat bread
• B. Vanilla malt
• C. Barley soup
• D. Rice pudding

Correct answer: D

Rationale: Celiac disease requires a lifelong gluten-free diet. Foods containing gluten such as wheat, barley, and rye should be avoided. Rice pudding is a safe option as it does not contain gluten, making it a suitable choice for a child with celiac disease.
