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 with a longstanding diagnosis of generalized anxiety disorder presents to the emergency room. The triage nurse notes upon assessment that the patient is hyperventilating. The triage nurse is aware that hyperventilation is the most common cause

• A. Respiratory acidosis
• B. Respiratory alkalosis
• C. Increased PaCO2
• D. CNS disturbances

Correct answer: B

Rationale:

3. 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.

4. A newly graduated nurse is admitting a patient with a long history of emphysema. The new nurses preceptor is going over the patients past lab reports with the new nurse. The nurse takes note that the patients PaCO2 has been between 56 and 64 mm Hg for several months. The preceptor asks the new nurse why they will be cautious administering oxygen. What is the new nurses best response?

• A. The patients calcium will rise dramatically due to pituitary stimulation.
• B. Oxygen will increase the patients intracranial pressure and create confusion.
• C. Oxygen may cause the patient to hyperventilate and become acidotic.
• D. Using oxygen may result in the patient developing carbon dioxide narcosis and hypoxemia.

Correct answer: D

Rationale:

5. You are performing an admission assessment on an older adult patient newly admitted for end-stage liver disease. What principle should guide your assessment of the patients skin turgor?

• A. Overhydration is common among healthy older adults.
• B. Dehydration causes the skin to appear spongy
• C. Inelastic skin turgor is a normal part of aging
• D. Skin turgor cannot be assessed in patients over 70.

Correct answer: C
