1. A healthcare professional is reviewing the results of an ABG performed on a client with chronic emphysema. Which of the following results suggests the need for further treatment?

A. PaO2 level of 89 mm Hg
B. PaCO2 level of 55 mm Hg
C. HCO3 level of 25 mEq/L
D. pH level of 7.37

Correct answer: B

Rationale: The correct answer is B. A high PaCO2 level (55 mm Hg) in a client with chronic emphysema suggests respiratory acidosis, which requires further treatment. In chronic emphysema, impaired gas exchange leads to elevated carbon dioxide levels in the blood. Option A (PaO2 level of 89 mm Hg) is near the normal range and does not indicate immediate treatment. Option C (HCO3 level of 25 mEq/L) and option D (pH level of 7.37) are within normal limits and do not suggest the need for further treatment in this context.

2. A nurse is reviewing the medical record of a client who has chronic kidney disease. The client's potassium level is 6.5 mEq/L. Which of the following actions should the nurse take?

A. Administer sodium bicarbonate
B. Administer sodium polystyrene sulfonate
C. Administer calcium gluconate
D. Administer calcium carbonate

Correct answer: B

Rationale: The correct answer is B: Administer sodium polystyrene sulfonate. Sodium polystyrene sulfonate is used to treat hyperkalemia by promoting the excretion of potassium. Choice A, administering sodium bicarbonate, is incorrect as it is not used to treat hyperkalemia. Choice C, administering calcium gluconate, is incorrect as it is used to treat hypocalcemia, not hyperkalemia. Choice D, administering calcium carbonate, is incorrect as it is used to treat conditions like osteoporosis and indigestion, not hyperkalemia.

3. Which lab value is most critical to monitor in a patient receiving digoxin?

A. Monitor potassium levels
B. Monitor sodium levels
C. Monitor calcium levels
D. Monitor magnesium levels

Correct answer: A

Rationale: The correct answer is to monitor potassium levels in a patient receiving digoxin. Hypokalemia can potentiate the toxic effects of digoxin, leading to serious cardiac arrhythmias. Monitoring potassium levels helps prevent toxicity. Monitoring sodium levels (Choice B), calcium levels (Choice C), and magnesium levels (Choice D) are also important aspects of patient care, but potassium levels are most critical in patients on digoxin therapy.

4. A client is 24 hours postoperative following a right-sided mastectomy. Which of the following interventions should the nurse include in the plan of care?

A. Place the client in the supine position.
B. Encourage the client to lift objects with the right arm.
C. Measure the client's blood pressure on the right arm.
D. Elevate the client's right arm on a pillow.

Correct answer: D

Rationale: Elevating the client's right arm on a pillow is essential post-mastectomy to reduce swelling and promote circulation. Placing the client in the supine position may not be comfortable or ideal after a mastectomy. Encouraging the client to lift objects with the right arm can strain the surgical site and hinder healing. Measuring the client's blood pressure on the right arm should be avoided to prevent disruption to the area and inaccurate readings.

5. Which electrolyte imbalance is most concerning in a patient on furosemide?

A. Hyperkalemia
B. Hypokalemia
C. Hyponatremia
D. Hypercalcemia

Correct answer: B

Rationale: The correct answer is Hypokalemia. Furosemide is a loop diuretic that can lead to potassium depletion by increasing its excretion in the urine. Hypokalemia is a common and concerning side effect of furosemide therapy. Hyperkalemia (Choice A) is less likely as furosemide tends to lower potassium levels. Hyponatremia (Choice C) is more commonly seen with thiazide diuretics. Hypercalcemia (Choice D) is not directly associated with furosemide use.
