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. A client is prescribed warfarin (Coumadin) for atrial fibrillation. Which dietary instruction should the nurse provide?

• A. Increase intake of green leafy vegetables
• B. Avoid foods high in vitamin K
• C. Increase intake of foods rich in vitamin C
• D. Limit intake of dairy products

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Vitamin K can decrease the effectiveness of warfarin, so it is essential for clients on warfarin therapy to avoid foods high in vitamin K. Green leafy vegetables are high in vitamin K, so choice A is incorrect. Choices C and D are unrelated to the dietary restrictions needed for clients taking warfarin and are therefore incorrect.

3. The nurse plans to evaluate the effectiveness of several drugs administered by different routes. Arrange the routes of administration from fastest to slowest rate of absorption. 1. Intravenous 2. Sublingual 3. Intramuscular 4. Subcutaneous

• A. 1,2,3,4
• B. 4,3,2,1
• C. 2,4,3,1
• D. 3,4,1,2

Correct answer: A

Rationale: The correct order of routes of administration from fastest to slowest rate of absorption is 1. Intravenous, 2. Sublingual, 3. Intramuscular, 4. Subcutaneous. Intravenous administration provides the fastest absorption as the drug is directly injected into the bloodstream. Sublingual administration allows for rapid absorption through the mucous membranes under the tongue. Intramuscular administration has a slower absorption rate as the drug is injected into the muscle tissue. Subcutaneous administration is the slowest as the drug is injected into the fatty tissue under the skin, leading to a slower absorption compared to the other routes.

4. The client is being educated by the nurse about the side effects of prednisone. Which side effect should the client be instructed to report immediately?

• A. Weight gain.
• B. Increased appetite.
• C. Hyperglycemia.
• D. Fever or sore throat.

Correct answer: D

Rationale: The correct answer is D: Fever or sore throat. These symptoms should be reported immediately as they could indicate an infection, which can be serious in clients taking prednisone due to its immunosuppressive effects. Choices A and B are common side effects of prednisone but are not typically considered urgent. Choice C, hyperglycemia, is a known side effect of prednisone but is not an immediate concern compared to the potential of an infection signaled by fever or sore throat.

5. A client with a diagnosis of hypothyroidism is prescribed levothyroxine (Synthroid). Which symptom should prompt the nurse to notify the healthcare provider?

• A. Weight gain.
• B. Bradycardia.
• C. Nervousness and tremors.
• D. Fatigue.

Correct answer: C

Rationale: The correct answer is C: 'Nervousness and tremors.' In a client with hypothyroidism prescribed levothyroxine, the development of nervousness and tremors may indicate hyperthyroidism, which can result from excessive dosing of levothyroxine. Therefore, the nurse should promptly notify the healthcare provider to adjust the medication dosage. Choices A, B, and D are incorrect because weight gain, bradycardia, and fatigue are more commonly associated with hypothyroidism itself, indicating that the levothyroxine therapy may not be effective enough, rather than being signs of excessive dosing.
