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. Which of the following are sources of water intake?

• A. Drinking fluids.
• B. Consuming water from the food we eat.
• C. Water from metabolic processes.
• D. Drinking fluids, consuming water from the food we eat, and water from metabolic processes.

Correct answer: D

Rationale: The correct answer is D. The sources of water intake include drinking fluids, consuming water from the food we eat, and water from metabolic processes. Water intake is not solely from the liquids we drink but also from the water content present in the food we consume and the water produced during metabolic processes such as cellular respiration. Therefore, option D is the correct answer as it covers all the sources of water intake. Options A, B, and C alone do not encompass all the sources of water intake, making them incorrect choices.

3. A nurse is caring for a client who has a serum calcium level of 14 mg/dL. Which provider order should the nurse implement first?

• A. Encourage oral fluid intake.
• B. Connect the client to a cardiac monitor.
• C. Assess urinary output.
• D. Administer oral calcitonin (Calcimar).

Correct answer: A

Rationale: The correct answer is to encourage oral fluid intake. With a serum calcium level of 14 mg/dL, the client is at risk of hypercalcemia. Encouraging oral fluid intake helps to promote hydration and can help prevent further elevation of calcium levels. Connecting the client to a cardiac monitor (Choice B) is important but not the first priority in this situation. Assessing urinary output (Choice C) is relevant but does not address the immediate concern of high serum calcium levels. Administering oral calcitonin (Calcimar) (Choice D) may be a treatment option later, but the first step should be to address hydration.

4. A nurse is caring for a client who is experiencing moderate metabolic alkalosis. Which action should the nurse take?

• A. Monitor daily hemoglobin and hematocrit values.
• B. Administer furosemide (Lasix) intravenously.
• C. Encourage the client to take deep breaths.
• D. Teach the client fall prevention measures.

Correct answer: D

Rationale:

5. . You are caring for a patient who has a diagnosis of syndrome of inappropriate antidiuretic hormone secretion (SIADH). Your patients plan of care includes assessment of specific gravity every 4 hours. The results of this test will allow the nurse to as

• A. Nutritional status
• B. Potassium balance
• C. Calcium balance
• D. Fluid volume status

Correct answer: D

Rationale:
