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 with cirrhosis is experiencing pruritus. Which intervention should the nurse include in the care plan?

• A. Administer antihistamines as prescribed
• B. Apply alcohol-based lotions to the skin
• C. Encourage frequent baths with hot water
• D. Limit fluid intake

Correct answer: A

Rationale: The correct answer is A: Administer antihistamines as prescribed. Pruritus, or itching, is a common symptom in clients with cirrhosis. Antihistamines can help relieve itching by blocking the effects of histamine. Applying alcohol-based lotions (choice B) can further dry out the skin and exacerbate itching. Encouraging frequent baths with hot water (choice C) can also worsen pruritus by stripping the skin of natural oils. Limiting fluid intake (choice D) is not directly related to managing pruritus in cirrhosis.

3. A client with a diagnosis of hypothyroidism is prescribed levothyroxine (Synthroid). What is the most important instruction the nurse should provide?

• A. Take the medication in the morning on an empty stomach
• B. Take the medication with food
• C. Report any symptoms of hyperthyroidism
• D. Do not discontinue the medication abruptly

Correct answer: C

Rationale: The correct answer is C: 'Report any symptoms of hyperthyroidism.' Symptoms of hyperthyroidism, such as palpitations or tremors, may indicate an excessive dose of levothyroxine and should be reported to the healthcare provider for proper adjustment of the medication. Choice A is incorrect because levothyroxine is usually taken in the morning on an empty stomach to maximize absorption. Choice B is incorrect because taking levothyroxine with food can interfere with its absorption. Choice D is incorrect because discontinuing levothyroxine abruptly can lead to a worsening of hypothyroidism symptoms.

4. Which client assessment falls within the scope of practice for the practical nurse?

• A. An agitated client with bilateral wrist restraints
• B. New admission of a client with deep vein thrombosis
• C. Return of a post-anesthesia client following a colon resection
• D. Transfer of a client with sepsis from a long-term care facility

Correct answer: B

Rationale: The correct answer is B because assessing a new deep vein thrombosis (DVT) patient is within the scope of practical nursing. It involves monitoring and supporting the circulatory system health, which is a common responsibility for practical nurses. Choices A, C, and D involve scenarios that are typically beyond the initial assessment and care provided by practical nurses. An agitated client with bilateral wrist restraints may require immediate intervention by higher-level healthcare providers due to safety concerns and potential underlying issues. The return of a post-anesthesia client following a colon resection and the transfer of a client with sepsis involve more specialized care that goes beyond the typical responsibilities of a practical nurse, often requiring interventions from registered nurses or physicians.

5. The healthcare provider reviews the laboratory results of a client whose serum pH is 7.38. What does this value imply about the client's homeostasis?

• A. Alkalosis
• B. Acidosis
• C. Normal serum pH
• D. Incompatible with life

Correct answer: C

Rationale: A pH of 7.38 falls within the normal range (7.35-7.45), indicating that the client’s acid-base balance is adequately maintained. Choices A and B are incorrect as alkalosis and acidosis refer to abnormal pH levels. Choice D is incorrect as a pH of 7.38 within the normal range is compatible with life.
