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 patient develops hypotension, laryngeal edema, and bronchospasm after eating peanuts. Which medication should the nurse prepare to administer?

• A. Promethazine
• B. Epinephrine
• C. Diphenhydramine
• D. Hydroxyzine

Correct answer: B

Rationale: The patient is exhibiting symptoms of anaphylaxis triggered by a peanut allergy, a severe and potentially life-threatening allergic reaction. The appropriate medication for anaphylaxis is epinephrine. Epinephrine acts quickly to reverse the symptoms by constricting blood vessels, relaxing bronchial muscles, and reducing laryngeal edema, making it the drug of choice for this situation. Promethazine, diphenhydramine, and hydroxyzine are not the first-line treatments for anaphylaxis. Promethazine is an antihistamine with sedative effects, Diphenhydramine is an antihistamine, and Hydroxyzine is also an antihistamine with sedative properties. While these medications can help with mild allergic reactions, they are not as effective or fast-acting as epinephrine in treating the severe manifestations of anaphylaxis.

3. When a patient is taking glucocorticoids and digoxin, which electrolyte should the nurse prioritize monitoring?

• A. Calcium
• B. Magnesium
• C. Sodium
• D. Potassium

Correct answer: D

Rationale: The nurse should primarily monitor potassium levels in a patient taking glucocorticoids and digoxin. Glucocorticoids can lead to potassium loss, potentially increasing the risk of digoxin toxicity. Additionally, glucocorticoids may worsen hypokalemia induced by diuretics like thiazides and loops. While calcium, magnesium, and sodium are important electrolytes to monitor in various clinical situations, they are not the priority in this specific scenario of a patient on glucocorticoids and digoxin.

4. A nurse is planning care to address nutritional needs for a preschooler with cystic fibrosis. Which interventions should the nurse include in plans?

• A. Administer pancreatic enzymes 2 hours after meals.
• B. Monitor and adjust the use of pancreatic enzymes if steatorrhea develops.
• C. Encourage adequate fluid intake based on the child's needs.
• D. Increase fat content in the child's diet to 40% of total calories.

Correct answer: D

Rationale: Increasing fat content in the diet is essential for meeting the high energy needs of a child with cystic fibrosis. Cystic fibrosis impairs the absorption of nutrients, particularly fats, so increasing the fat content in the child's diet to 40% of total calories helps ensure adequate caloric intake. This intervention can help maintain the child's nutritional status and support growth and development.

5. Which statement is true concerning early intervention services for children 0-2 years?

• A. Only healthcare professionals can determine if the child is eligible for services
• B. Specific diagnoses are not required to qualify for services
• C. Families must not pay for services
• D. Services are provided to a diverse group of children and families

Correct answer: D

Rationale: Early intervention services aim to support a diverse group of children and families without the need for a specific diagnosis. These services are inclusive and provided to all eligible children and families, regardless of their background or particular condition.
