ATI Fluid Electrolyte and Acid-Base Regulation

1. The physician has ordered a peripheral IV to be inserted before the patient goes for computed tomography. What should the nurse do when selecting a site on the hand or arm for insertion of an IV catheter?

Correct answer: B

Rationale:

2. Which electrolyte is important in the formation of the thyroid hormones?

Correct answer: B

Rationale: Iodine is the correct answer because it is essential for the synthesis of thyroid hormones. The thyroid gland incorporates iodine into thyroid hormones such as thyroxine (T4) and triiodothyronine (T3). These hormones are crucial for regulating metabolism, growth, and development. Sodium, iron, and chloride are not directly involved in the formation of thyroid hormones, making them incorrect choices.

3. A patient who is hospitalized with a possible electrolyte imbalance is disoriented and weak, has an irregular pulse, and takes hydrochlorothiazide. He most likely suffers from:

Correct answer: D

Rationale: The patient is displaying symptoms of hypokalemia, including weakness, disorientation, irregular pulse, which can lead to cardiac disturbances. Hydrochlorothiazide is a potassium-wasting diuretic that can cause hypokalemia if not accompanied by potassium replacement therapy. Hypernatremia (choice A) is characterized by high sodium levels, not potassium. Hyponatremia (choice B) is low sodium levels. Hyperkalemia (choice C) is high potassium levels, which is not consistent with the symptoms described in the question.

4. A nurse is planning care for a client who is hyperventilating. The clients arterial blood gas values are pH 7.30, PaO2 94 mm Hg, PaCO2 31 mm Hg, and HCO3 26 mEq/L. Which question should the nurse ask when developing this clients plan of care?

Correct answer: B

Rationale:

5. A patient who is in renal failure partially loses the ability to regulate changes in pH because the kidneys:

Correct answer: C

Rationale: The correct answer is C. In renal failure, the kidneys lose the ability to regulate pH by controlling bicarbonate levels in the extracellular fluid (ECF). The kidneys can regenerate and reabsorb bicarbonate ions to maintain a stable pH. Choices A, B, and D are incorrect because the kidneys do not primarily regulate or reabsorb carbonic acid, buffer acids through electrolyte changes, or combine carbonic acid and bicarbonate to maintain pH. The key function of the kidneys in maintaining pH balance lies in the control of bicarbonate levels.
