1. The renin and angiotensin systems help to maintain the balance of sodium and water in the body. What other functions do these systems serve?

Correct answer: B

Rationale: The correct answer is B: Maintaining a healthy blood volume. The renin and angiotensin systems not only help to regulate sodium and water balance in the body but also play a crucial role in maintaining an adequate blood volume. This is essential for normal blood pressure regulation and overall cardiovascular health. Choices A, C, and D are incorrect because hemoglobin levels are primarily regulated by the bone marrow and erythropoietin, platelets are released in response to blood vessel injury by a different mechanism, and the systems do not focus on lowering blood volumes but rather on maintaining them.

2. While assessing a clients peripheral IV site, the nurse observes a streak of red along the vein path and palpates a 4-cm venous cord. How should the nurse document this finding?

Correct answer: A

Rationale:

3. A nurse is assessing clients who have intravenous therapy prescribed. Which assessment finding for a client with a peripherally inserted central catheter (PICC) requires immediate attention?

Correct answer: D

Rationale:

4. Extracellular fluid includes:

Correct answer: C

Rationale: The correct answer is C: 'plasma and interstitial fluid.' Extracellular fluid consists of all body fluids outside the cells, primarily including plasma (the liquid component of blood) and interstitial fluid (the fluid between cells). Choices A, B, and D are incorrect because intracellular fluid is located within the cells, not in the extracellular fluid compartment.

5. A 65-year-old male patient was admitted to a medical-surgical unit 72 hours ago with pyloric stenosis; a nasogastric tube was inserted upon admission and has been on low intermittent suction since then. The nurse taking care of the patient notices that his potassium is very low and becomes concerned that the patient may be at risk for:

Correct answer: C

Rationale: The correct answer is C, metabolic alkalosis. The patient with pyloric stenosis has been on low intermittent suction, leading to the loss of hydrogen and chloride ions. This condition causes metabolic alkalosis due to the removal of these ions. Options A (Hypercalcemia) and D (Respiratory acidosis) are incorrect as they are not directly related to the scenario described. Option B (Metabolic acidosis) is also incorrect; in this case, the patient is at risk of metabolic alkalosis due to the loss of hydrogen and chloride ions through gastric suction.
