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 school-age child has peripheral edema. Which of the following assessments should the nurse perform to confirm peripheral edema?

• A. Palpate the dorsum of the child's feet
• B. Weigh the child daily using the same scale
• C. Assess the child's skin turgor
• D. Observe the child for periorbital swelling

Correct answer: A

Rationale: To confirm peripheral edema in a child, the nurse should palpate the dorsum of the child's feet by pressing a fingertip against a bony prominence for 5 seconds. This assessment helps detect the presence of pitting edema, which is characterized by an indentation that remains after the pressure is released.

3. Which menu choices for a child diagnosed with renal failure and experiencing hyperkalemia indicate the need for further instruction by the nurse?

• A. Carrots and green, leafy vegetables
• B. Spaghetti and meat sauce with breadsticks
• C. Hamburger on a bun and cherry gelatin
• D. Chips, cold cuts, and canned foods

Correct answer: A

Rationale: Carrots and green, leafy vegetables are high in potassium, which should be avoided in hyperkalemia. Therefore, this choice requires further instruction by the nurse to prevent exacerbating the child's condition.

4. A child is being cared for following a head injury. Which of the following findings should indicate to the healthcare provider that the child is developing diabetes insipidus?

• A. Urine specific gravity of 1.045
• B. Sodium level of 155
• C. Blood glucose level of 45
• D. Urine output of 35 ml per hour

Correct answer: B

Rationale: In a child with a head injury, the development of diabetes insipidus can occur due to pituitary hypofunction, leading to a deficiency of antidiuretic hormone. An elevated sodium level (hypernatremia) is a key finding in diabetes insipidus due to the excessive loss of free water in the urine, resulting in increased sodium concentration in the blood.

5. A patient is 1 hour postoperative following an open reduction internal fixation of the left tibia. Which of the following actions should the nurse take?

• A. Assess neurovascular status of the extremities every 4 hours
• B. Monitor the patient's pain level every 8 hours
• C. Assist the patient to the bathroom every 2 hours
• D. Keep the patient's left leg elevated on two pillows

Correct answer: A

Rationale: The correct action for the nurse to take 1 hour postoperative following an open reduction internal fixation of the left tibia is to assess neurovascular status of the extremities every 4 hours. This frequent assessment is crucial to monitor for any signs of complications such as impaired circulation or nerve damage. Monitoring every 4 hours allows for early detection of any issues, enabling timely intervention and prevention of potential complications. Monitoring the patient's pain level every 8 hours (choice B) is not as immediate or essential for postoperative care. Assisting the patient to the bathroom every 2 hours (choice C) may not be necessary if the patient is not ambulatory yet. Keeping the patient's left leg elevated on two pillows (choice D) can be beneficial but is not the priority in the immediate postoperative period compared to assessing neurovascular status.
