ATI Fluid Electrolyte and Acid-Base Regulation

1. A home care nurse prepares to administer intravenous medication to a client. The nurse assesses the site and reviews the clients chart prior to administering the medication: Client: Thomas Jackson DOB: 5/3/1936 Gender: Male January 23 (Today): Right uppe

Correct answer: B

Rationale:

2. Which mineral is important in hemoglobin production?

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.

3. A patient who is in renal failure partially loses the ability to regulate changes in pH because the kidneys:

Correct answer: C

Rationale: The correct answer is C. In renal failure, the kidneys lose the ability to regulate pH by controlling bicarbonate levels in the extracellular fluid (ECF). The kidneys can regenerate and reabsorb bicarbonate ions to maintain a stable pH. Choices A, B, and D are incorrect because the kidneys do not primarily regulate or reabsorb carbonic acid, buffer acids through electrolyte changes, or combine carbonic acid and bicarbonate to maintain pH. The key function of the kidneys in maintaining pH balance lies in the control of bicarbonate levels.

4. 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?

Correct answer: B

Rationale: When selecting a site for IV insertion on the hand or arm, it is important to consider the potential effects on the patient's mobility. The chosen site should not interfere with the patient's movement. Instructing the patient to hold his arm in a dependent position helps increase blood flow, aiding in vein visualization and insertion. It is advisable to choose a site with minimal hair if possible for better adhesion of the dressing. Removing the tourniquet after 2 minutes is recommended to prevent complications like hemoconcentration and potential vein damage. Therefore, option B is the correct choice as it aligns with best practices for IV insertion.

5. Which hormone is made in the pituitary gland and increases water absorption in the kidney?

Correct answer: D

Rationale: The correct answer is D, ADH (Antidiuretic hormone). ADH is produced by the pituitary gland and functions to increase water reabsorption in the kidneys. Choices A, B, and C are incorrect as they do not refer to a hormone responsible for increasing water absorption in the kidney.
