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. A nurse is assessing a client with hypokalemia and notes that the client's handgrip strength has diminished since the previous assessment 1 hour ago. Which action should the nurse take first?

• A. Assess the client's respiratory rate, rhythm, and depth.
• B. Measure the client's pulse and blood pressure.
• C. Document findings and monitor the client.
• D. Call the healthcare provider.

Correct answer: A

Rationale: In a client with hypokalemia experiencing diminished handgrip strength, the priority action for the nurse is to assess the client's respiratory rate, rhythm, and depth. Hypokalemia can lead to muscle weakness, including respiratory muscles, potentially causing respiratory distress. Assessing the respiratory status is crucial to determine if immediate interventions are needed to maintain adequate oxygenation. Measuring the client's pulse and blood pressure (Choice B) is important but should come after assessing the respiratory status. Simply documenting findings and monitoring the client (Choice C) may delay necessary interventions. Calling the healthcare provider (Choice D) is not the first action indicated in this situation; assessing the client's respiratory status takes precedence.

3. 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?

• A. Choose a hairless site if available.
• B. Consider potential effects on the patients mobility when selecting a site.
• C. Have the patient briefly hold his arm over his head before insertion
• D. Leave the tourniquet on for at least 3 minutes.

Correct answer: B

Rationale:

4. The nurse is caring for a patient in metabolic alkalosis. The patient has an NG tube to low intermittent suction for a diagnosis of bowel obstruction. What drug would the nurse expect to find on the medication orders?

• A. Cimetidine
• B. Maalox
• C. Potassium chloride elixir
• D. ) Furosemide

Correct answer: A

Rationale:

5. Which of the following organs does not contribute to fluid output from the body?

• A. Lungs
• B. Skin
• C. Intestine
• D. Lungs, skin, and intestine

Correct answer: D

Rationale: The correct answer is D. All the listed organs (lungs, skin, and intestines) contribute to fluid loss from the body. Lungs contribute to fluid loss through respiration, skin through sweating, and intestines through excretion. Therefore, none of the organs listed in the options retain fluids within the body. Choices A, B, and C are incorrect because all of these organs play a role in fluid output from the body.
