1. . A nurse assesses a client who had an intraosseous catheter placed in the left leg. Which assessment finding is of greatest concern?

Correct answer: D

Rationale:

2. The nurse in the intensive care unit receives arterial blood gases (ABG) with a patient who is complaining of being 'short of breath.' The ABG has the following values: pH = 7.21, PaCO2 = 64 mm Hg, HCO3 = 24 mmol/L. The labs reflect:

Correct answer: A

Rationale: The ABG values indicate respiratory acidosis. A pH below 7.40, a PaCO2 above 40 mm Hg, and a normal HCO3 level (24 mmol/L) suggest respiratory acidosis. In this case, the patient has an acidic pH (7.21) and an elevated PaCO2 (64 mm Hg), indicating inadequate ventilation. The normal HCO3 level suggests that compensation by the kidneys has not occurred, implying an acute event. Choices B, C, and D can be ruled out based on the given ABG values and the criteria for acid-base disorders.

3. A nurse develops a plan of care for a client who has a history of hypocalcemia. What interventions should the nurse include in this clients care plan? (Select all that apply.)

Correct answer: B

Rationale:

4. Which of the following is not considered an extracellular fluid?

Correct answer: D

Rationale: The correct answer is D. Cerebrospinal fluid and the humors of the eye are not considered extracellular fluids. Extracellular fluids are fluids found outside the cells, such as interstitial fluid and lymph. Cerebrospinal fluid is found within the central nervous system, while the humors of the eye (aqueous humor and vitreous humor) are located within the eyeball, making them distinct from extracellular fluids.

5. A nurse is assessing clients on a medical-surgical unit. Which clients are at increased risk for hypophosphatemia? (Select all that do not apply.)

Correct answer: C

Rationale:
