Nursing Elites

1. A nurse in the neurologic ICU has orders to infuse a hypertonic solution into a patient with increased intracranial pressure. This solution will increase the number of dissolved particles in the patients blood, creating pressure for fluids in the tissues to shift into the capillaries and increase the blood volume. This process is best described as which of the following?

• A. Hydrostatic pressure
• B. Osmosis and osmolality
• C. Diffusion
• D. Active transport

Correct answer: B

Rationale:

2. A nurse is assessing clients for fluid and electrolyte imbalances. Which client should the nurse assess first for potential hyponatremia?

• A. A 34-year-old on NPO status who is receiving intravenous D5W
• B. A 50-year-old with an infection who is prescribed a sulfonamide antibiotic
• C. A 67-year-old who is experiencing pain and is prescribed ibuprofen (Motrin)
• D. A 73-year-old with tachycardia who is receiving digoxin (Lanoxin)

Correct answer: A

Rationale: The correct answer is the 34-year-old on NPO status receiving intravenous D5W because D5W is a hypotonic solution that can dilute the blood's sodium levels, leading to hyponatremia. Patients on NPO status rely solely on intravenous fluids for hydration, making them more susceptible to electrolyte imbalances. Choices B, C, and D are less likely to cause hyponatremia. Choice B, the 50-year-old with an infection on a sulfonamide antibiotic, is at risk for allergic reactions or renal issues. Choice C, the 67-year-old taking ibuprofen, is at risk for gastrointestinal bleeding or kidney problems. Choice D, the 73-year-old on digoxin with tachycardia, is more likely to experience digoxin toxicity, affecting the heart's rhythm.

3. The triage nurse notes upon assessment in the emergency room that the patient with anxiety is hyperventilating. The nurse is aware that hyperventilation is the most common cause of which acid-base imbalance?

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

Correct answer: B

Rationale: The correct answer is B: Respiratory alkalosis. Hyperventilation is the most common cause of acute respiratory alkalosis. When a patient hyperventilates due to anxiety or other causes, they blow off excessive carbon dioxide, leading to a decrease in PaCO2 and a rise in pH. Choices A, C, and D are incorrect because hyperventilation leads to a decrease in PaCO2, causing respiratory alkalosis, not respiratory acidosis, metabolic acidosis, or metabolic alkalosis.

4. What is the fluid inside the cell called?

• A. Plasma
• B. Intracellular fluid
• C. Interstitial fluid
• D. Plasma and intracellular fluid

Correct answer: B

Rationale: The correct answer is 'Intracellular fluid.' Intracellular fluid refers to the fluid contained within the cells, constituting a significant portion of the body's total water content. Choices A, C, and D are incorrect. Plasma is the liquid component of blood outside the cells, interstitial fluid is the fluid surrounding cells in tissues, and the combination of plasma and intracellular fluid is not the specific term for the fluid inside the cell.

5. A medical-surgical nurse is concerned about the incidence of complications related to IV therapy, including bloodstream infection. Which intervention should the nurse suggest to the management team to make the biggest impact on decreasing complications

• A. Initiate a dedicated team to insert access devices
• B. . Require additional education for all nurses.
• C. Limit the use of peripheral venous access devices.
• D. Perform quality control testing on skin preparation products.

Correct answer: A
