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. A client complains of pain at the IV site. Upon assessment, the nurse notes the site is warm, red, and swollen. What is the most likely cause of these findings?

• A. Phlebitis
• B. Infiltration
• C. Allergic reaction
• D. Fluid overload

Correct answer: A

Rationale: The correct answer is A, Phlebitis. Phlebitis is the inflammation of a vein, often caused by irritation from an IV catheter, resulting in warmth, redness, and swelling at the site. Infiltration (choice B) refers to the leaking of IV fluids into the surrounding tissues, causing swelling and pallor, not redness and warmth like in the scenario described. An allergic reaction (choice C) would present with itching, hives, or anaphylaxis, rather than localized warmth, redness, and swelling. Fluid overload (choice D) typically manifests as generalized edema, shortness of breath, and weight gain, not localized symptoms at the IV site.

3. The nurse is monitoring a client's intravenous infusion and observes that the venipuncture site is cool to the touch, swollen, and the infusion rate is slower than the prescribed rate. What is the most likely cause of this finding?

• A. The solution's rate is too rapid
• B. The client has phlebitis
• C. The infusion site is infected
• D. The infusion is infiltrated

Correct answer: D

Rationale: The correct answer is D. An infiltrated IV occurs when fluid leaks into the surrounding tissue, causing coolness, swelling, and a slow infusion rate. Choice A is incorrect because a rapid solution rate does not typically cause these specific symptoms. Choice B, phlebitis, presents with redness, warmth, and tenderness along the vein, not coolness. Choice C, infection, usually manifests with redness, warmth, and possibly purulent drainage, not coolness and swelling.

4. After morning dressing changes, a male client with paraplegia contaminates his ischial decubiti dressing with diarrheal stool. What is the best activity for the nurse to assign to the unlicensed assistive personnel (UAP)?

• A. Identify the need for additional supplies for an extra dressing change
• B. Provide perianal care and collect clean linens for the dressing change
• C. Document the diarrhea that necessitates an additional dressing change
• D. Position the client for access to the decubiti sites and remove dressings

Correct answer: B

Rationale: The best activity for the nurse to assign to the unlicensed assistive personnel (UAP) in this situation is to provide perianal care and collect clean linens for the dressing change. This task is crucial to maintain proper hygiene, prevent infection, and promote healing in the areas affected by decubiti. Choice A is not the priority as addressing the contamination and ensuring hygiene is more critical. Choice C is not the immediate concern and does not address the current situation. Choice D involves direct client care tasks that should be handled by licensed nursing staff.

5. The client with high blood pressure is being taught by the nurse to avoid adding salt during cooking. What effect does sodium have on blood pressure?

• A. It decreases the viscosity of blood
• B. It leads to increased fluid retention
• C. It causes vasoconstriction of the blood vessels
• D. It enhances the excretion of potassium

Correct answer: C

Rationale: The correct answer is C: 'It causes vasoconstriction of the blood vessels.' Sodium can lead to vasoconstriction, which narrows the blood vessels, increasing resistance to blood flow and subsequently raising blood pressure. Choices A, B, and D are incorrect. Sodium does not decrease blood viscosity, but it can lead to fluid retention, which increases blood volume and pressure. It does not enhance the excretion of potassium; instead, high sodium intake can lead to potassium excretion by the kidneys.
