Nursing Elites

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

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

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.

2. You are the surgical nurse caring for a 65-year-old female patient who is postoperative day 1 following a thyroidectomy. During your shift assessment, the patient complains of tingling in her lips and fingers. She tells you that she has an intermittent spasm in her wrist and hand, and she exhibits increased muscle tone. What electrolyte imbalance should you first suspect?

• A. Hypophosphatemia
• B. Hypocalcemia
• C. Hypermagnesemia
• D. Hyperkalemia

Correct answer: B

Rationale: The symptoms described, including tingling in the lips and fingers, intermittent spasms, and increased muscle tone, are indicative of tetany, which is a common manifestation of hypocalcemia. Hypocalcemia can lead to neuromuscular irritability, causing symptoms such as paresthesias and muscle spasms. Hypophosphatemia primarily affects the central nervous system, resulting in seizures and coma. Hypermagnesemia typically presents with hypoactive reflexes and somnolence. Hyperkalemia can cause paresthesias and anxiety, but in this case, the patient's symptoms are more suggestive of hypocalcemia.

3. 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

Rationale:

4. 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.)

• A. Use a draw sheet to reposition the client in bed.
• B. . Strain all urine output and assess for urinary stones.
• C. Provide nonslip footwear for the client to use when out of bed.
• D.

Correct answer: B

Rationale:

5. What is the fluid inside the cell called?

• A. Plasma
• B. Intracellular fluid
• C. Interstitial fluid
• D. Plasma and intracellular fluid

Correct answer: B

Rationale: The correct answer is 'Intracellular fluid.' Intracellular fluid refers to the fluid contained within the cells, constituting a significant portion of the body's total water content. Choices A, C, and D are incorrect. Plasma is the liquid component of blood outside the cells, interstitial fluid is the fluid surrounding cells in tissues, and the combination of plasma and intracellular fluid is not the specific term for the fluid inside the cell.
