1. What is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space?

• A. Filtration
• B. Diffusion
• C. Osmosis
• D. Active transport

Correct answer: C

Rationale: The correct answer is C: Osmosis. Osmosis is the homeostatic cellular transport mechanism that moves water from a hypotonic to a hypertonic fluid space to maintain cellular balance. In osmosis, water moves across a semi-permeable membrane from an area of low solute concentration (hypotonic) to an area of high solute concentration (hypertonic). This process helps regulate the water content inside cells. Choices A, B, and D are incorrect. Filtration involves the movement of solutes and solvents through a membrane due to a pressure difference, diffusion is the movement of solutes from an area of high concentration to low concentration, and active transport requires energy to move substances against their concentration gradient.

2. The nurse is assessing a client with an IV infusion of normal saline. The client reports pain and swelling at the IV site. What should the nurse do first?

• A. Slow the rate of infusion
• B. Apply a warm compress to the site
• C. Elevate the affected arm
• D. Discontinue the IV infusion

Correct answer: D

Rationale: The correct answer is to discontinue the IV infusion. Pain and swelling at the IV site may indicate infiltration or phlebitis, which requires immediate discontinuation of the infusion to prevent further complications. Continuing the infusion can lead to tissue damage or infection. Slowing the rate of infusion, applying a warm compress, or elevating the affected arm would not address the underlying issue of infiltration or phlebitis and could potentially worsen the condition by allowing more fluid to infiltrate the tissues.

3. A client with a diagnosis of chronic heart failure is receiving digoxin. What is the most important instruction the nurse should provide?

• A. Take the medication with a high-fiber meal
• B. Monitor pulse rate daily before taking the medication
• C. Avoid dairy products while on this medication
• D. Discontinue the medication if blurred vision is experienced

Correct answer: B

Rationale: The most important instruction the nurse should provide is to monitor pulse rate daily before taking the medication. Digoxin can lead to bradycardia, so it is crucial to assess the pulse rate before administering the medication. This practice helps ensure that the heart rate is not too low for the safe use of digoxin. Choice A is incorrect as there is no specific requirement to take digoxin with a high-fiber meal. Choice C is also incorrect because there is no need to avoid dairy products while on digoxin. Choice D is incorrect since blurred vision is not a common side effect of digoxin; hence, it is not the most critical instruction to provide.

4. A client with chronic kidney disease (CKD) is receiving erythropoietin therapy. What is the primary purpose of this medication?

• A. To lower blood pressure
• B. To improve appetite
• C. To increase red blood cell production
• D. To reduce fluid retention

Correct answer: C

Rationale: The correct answer is C: 'To increase red blood cell production.' Erythropoietin stimulates the production of red blood cells to treat anemia associated with CKD. Choices A, B, and D are incorrect because erythropoietin therapy is primarily used to address anemia by increasing the production of red blood cells rather than lowering blood pressure, improving appetite, or reducing fluid retention.

5. A client with a diagnosis of chronic kidney disease (CKD) is receiving epoetin alfa (Epogen). What is the primary goal of this medication?

• A. To reduce the risk of bleeding.
• B. To lower blood pressure.
• C. To stimulate red blood cell production.
• D. To increase appetite.

Correct answer: C

Rationale: The correct answer is C: 'To stimulate red blood cell production.' Epoetin alfa, such as Epogen, is used to treat anemia by stimulating red blood cell production in clients with chronic kidney disease. This medication helps increase hemoglobin levels and reduce the need for blood transfusions. Option A, 'To reduce the risk of bleeding,' is incorrect as epoetin alfa does not directly impact bleeding risk. Option B, 'To lower blood pressure,' is incorrect as epoetin alfa is not indicated for blood pressure management. Option D, 'To increase appetite,' is also incorrect as the primary goal of epoetin alfa is related to improving anemia by boosting red blood cell production.
