Nursing Elites

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 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.

3. A client has a prescription for a Transcutaneous Electrical Nerve Stimulator (TENS) unit for pain management during the postoperative period following a Lumbar Laminectomy. What information should the nurse reinforce about the action of this adjuvant pain modality?

• A. Mild electrical stimulus on the skin surface closes the gates of nerve conduction for severe pain
• B. Pain perception in the cerebral cortex is dulled by the unit's discharge of an electrical stimulus
• C. An infusion of medication in the spinal canal will block pain perception
• D. The discharge of electricity will distract the client's focus on the pain

Correct answer: A

Rationale: The correct answer is A. TENS units work by delivering small electrical impulses through the skin. These impulses are thought to close the 'gates of nerve conduction,' which can help in managing severe pain. Choice B is incorrect because the dulled pain perception does not occur in the cerebral cortex by the TENS unit. Choice C is incorrect as it describes a different method of pain management involving medication in the spinal canal. Choice D is incorrect because TENS does not work by distracting the client's focus on pain, but rather by altering pain perception through electrical impulses.

4. A client requires application of an eye shield to the right eye. What should the nurse do in order to apply tape to anchor the shield most effectively?

• A. Place tape from the cheek to the forehead
• B. Secure tape from the nose to the ear
• C. Attach tape from the lower eyelid to the upper forehead
• D. Use circular bandaging around the head

Correct answer: C

Rationale: The correct way to apply tape to anchor an eye shield effectively is to attach the tape from the lower eyelid to the upper forehead. This method provides stability for the shield without putting pressure on the eye itself, thus helping to protect the eye. Choices A, B, and D are incorrect because taping from the cheek to the forehead, securing tape from the nose to the ear, or using circular bandaging around the head may not provide the necessary stability and protection required for the eye shield.

5. The nurse is assessing a client with chronic liver disease. Which lab value is most concerning?

• A. Elevated AST and ALT levels
• B. Decreased albumin level
• C. Elevated bilirubin level
• D. Prolonged PT/INR

Correct answer: D

Rationale: In a client with chronic liver disease, a prolonged PT/INR is the most concerning lab value. This finding indicates impaired liver function affecting the synthesis of clotting factors, leading to an increased risk of bleeding. Elevated AST and ALT levels (Choice A) indicate liver cell damage but do not directly correlate with the risk of bleeding. A decreased albumin level (Choice B) is common in liver disease but is not the most concerning in terms of bleeding risk. Elevated bilirubin levels (Choice C) are seen in liver disease but do not directly reflect the risk of bleeding as PT/INR values do.
