ATI Fluid Electrolyte and Acid-Base Regulation

1. You are the nurse caring for a patient who is to receive IV daunorubicin, a chemotherapeutic agent. You start the infusion and check the insertion site as per protocol. During your most recent check, you note that the IV has infiltrated so you stop the infusion. What is your main concern with this infiltration?

A. Extravasation of the medication
B. Discomfort to the patient
C. Blanching at the site
D. Hypersensitivity reaction to the medication

Correct answer: A

Rationale:

2. A nurse teaches a client who is being discharged home with a peripherally inserted central catheter (PICC). Which statement should the nurse include in this clients teaching?

A. avoid carrying your grandchild with the arm that has the central catheter.
B. Be sure to place the arm with the central catheter in a sling during the day
C. Flush the peripherally inserted central catheter line with normal saline daily.
D. You can use the arm with the central catheter for most activities of daily living.

Correct answer: A

Rationale:

3. Which hormone reduces the amount of water in the body?

A. ADH
B. aldosterone
C. ANH
D. ADH and aldosterone

Correct answer: B

Rationale: The correct answer is 'aldosterone.' Aldosterone is the hormone that reduces the amount of water in the body by increasing the reabsorption of sodium and water from the kidney tubules. ANH (atrial natriuretic hormone) actually works to increase the excretion of sodium and water by the kidneys, leading to a reduction in blood volume and pressure. ADH (antidiuretic hormone) works to increase water reabsorption by the kidneys, thereby increasing blood volume. Therefore, choices A (ADH) and D (ADH and aldosterone) are incorrect in the context of reducing the amount of water in the body.

4. 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.

5. 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.
