Nursing Elites

1. Third spacing occurs when fluid moves out of the intravascular space but not into the intracellular space. Based on this fluid shift, the nurse will expect the patient to demonstrate:

• A. Hypertension
• B. Bradycardia
• C. Hypervolemia
• D. Hypovolemia

Correct answer: D

Rationale: In the scenario of third-spacing fluid shift, where fluid moves out of the intravascular space but not into the intracellular space, the patient is expected to demonstrate hypovolemia. Hypertension (Choice A) is unlikely as hypovolemia typically leads to decreased blood pressure. Bradycardia (Choice B) is not a common manifestation of hypovolemia, as the body often tries to compensate by increasing heart rate. Hypervolemia (Choice C) indicates an excess of fluid, which is the opposite of what occurs in third spacing.

2. A patient's lab results show a slight decrease in potassium. The physician has declined to treat with drug therapy but has suggested increasing the potassium through diet. Which of the following would be a good source of potassium?

• A. Apples
• B. Asparagus
• C. Carrots
• D. Bananas

Correct answer: D

Rationale: Bananas are an excellent source of potassium, making them a good choice to increase potassium levels through diet. While apples, asparagus, and carrots are nutritious, they are not particularly high in potassium compared to bananas. Therefore, choosing bananas would be more effective in increasing the patient's potassium intake.

3. The healthcare professional working in the PACU is aware that which of the following procedures may contribute to extracellular losses?

• A. Removal of an ingrown toenail
• B. Tooth extraction
• C. Abdominal surgery
• D. Cataract surgery

Correct answer: C

Rationale: Fluid loss from the extracellular compartment can be caused by abdominal surgery as it involves opening the abdominal cavity, potentially leading to significant fluid losses. Choices A, B, and D do not typically result in substantial extracellular losses compared to abdominal surgery.

4. A patient with a longstanding diagnosis of generalized anxiety disorder presents to the emergency room. The triage nurse notes upon assessment that the patient is hyperventilating. The triage nurse is aware that hyperventilation is the most common cause

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Increased PaCO2
• D. CNS disturbances

Correct answer: B

Rationale:

5. What fluid is found in spaces between the cells?

• A. Intracellular fluid
• B. Interstitial fluid
• C. Plasma
• D. Electrolyte

Correct answer: B

Rationale: The correct answer is B, Interstitial fluid. Interstitial fluid is the fluid that surrounds and occupies the spaces between cells, providing them with nutrients and removing waste. Choices A, C, and D are incorrect because intracellular fluid refers to fluid inside cells, plasma refers to the liquid component of blood, and electrolyte refers to substances that dissociate into ions in solution, affecting fluid balance but not specifically found in spaces between cells.
