1. Which mineral is important in hemoglobin production?

• A. Sodium
• B. Iodine
• C. Iron
• D. Chloride

Correct answer: C

Rationale: Iron (Fe) is a critical mineral in hemoglobin production. Hemoglobin is a protein found in red blood cells that is essential for transporting oxygen throughout the body. Sodium (Choice A), Iodine (Choice B), and Chloride (Choice D) are not directly involved in hemoglobin production. Sodium is an electrolyte that helps maintain fluid balance, Iodine is essential for thyroid hormone production, and Chloride is an electrolyte that helps regulate fluid balance and acidity in the body.

2. 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:

• A. Hypernatremia
• B. Hyponatremia
• C. Hyperkalemia
• D. Hypokalemia

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.

3. The nurse caring for a patient post colon resection is assessing the patient on the second postoperative day. The nasogastric tube (NG) remains patent and continues at low intermittent wall suction. The IV is patent and infusing at 125 mL/hr. The patient reports pain at the incision site rated at a 3 on a 0-to-10 rating scale. During your initial shift assessment, the patient complains of cramps in her legs and a tingling sensation in her feet. Your assessment indicates decreased deep tendon reflexes (DTRs) and you suspect the patient has hypokalemia. What other sign or symptom would you expect this patient to exhibit

• A. Diarrhea
• B. Dilute urine
• C. Increased muscle tone
• D. Joint pain

Correct answer: B

Rationale:

4. Where is the largest volume of water in the body located?

• A. Plasma
• B. The fluid inside the cells
• C. Interstitial fluid
• D. Lymph

Correct answer: B

Rationale: The correct answer is B. The largest volume of water in the body is found inside the cells, known as intracellular fluid. This fluid makes up the majority of the body's total water content. Choices A, C, and D are incorrect because while plasma, interstitial fluid, and lymph are important components of the body's fluid compartments, they do not contain the largest volume of water in the body.

5. A nurse assesses a client who is admitted with an acid-base imbalance. The clients arterial blood gas values are pH 7.32, PaO2 85 mm Hg, PaCO2 34 mm Hg, and HCO3 16 mEq/L. What action should the nurse take next?

• A. Assess clients rate, rhythm, and depth of respiration.
• B. Measure the clients pulse and blood pressure.
• C. Document the findings and continue to monitor.
• D. Notify the physician as soon as possible.

Correct answer: A
