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 nurse is assessing a client with cirrhosis who has developed ascites. What is the most important intervention to include in the care plan?

• A. Restrict sodium intake
• B. Encourage high-protein meals
• C. Increase fluid intake
• D. Administer diuretics as prescribed

Correct answer: D

Rationale: The correct answer is to administer diuretics as prescribed. Diuretics are often prescribed to help manage fluid accumulation in ascites, which is a common complication of cirrhosis. Restricting sodium intake (Choice A) is essential in managing ascites, but administering diuretics takes precedence in the care plan. Encouraging high-protein meals (Choice B) and increasing fluid intake (Choice C) are not the primary interventions for managing ascites in cirrhosis.

3. 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.

4. What is the primary function of neutrophils?

• A. Heparin secretion
• B. Transport oxygen
• C. Phagocytotic action
• D. Antibody formation

Correct answer: C

Rationale: The correct answer is C: Phagocytotic action. Neutrophils are key components of the immune system, primarily involved in the phagocytosis of bacteria and other pathogens. Choice A, Heparin secretion, is incorrect as heparin is primarily secreted by mast cells and basophils. Choice B, Transport oxygen, is incorrect as this is mainly the function of red blood cells. Choice D, Antibody formation, is incorrect as antibody production is primarily carried out by B lymphocytes.

5. What is the priority nursing action during the immediate postoperative period for a client who just underwent a coronary artery bypass graft?

• A. Monitor for signs of infection
• B. Ensure the client is pain-free
• C. Assess for bleeding and arrhythmias
• D. Maintain a patent airway

Correct answer: D

Rationale: Maintaining a patent airway is the priority nursing action during the immediate postoperative period for a client who just underwent a coronary artery bypass graft. This is crucial to ensure adequate oxygenation, especially in the early recovery phase. Monitoring for signs of infection, ensuring the client is pain-free, and assessing for bleeding and arrhythmias are important aspects of postoperative care but maintaining a clear airway takes precedence in this scenario to prevent hypoxia and respiratory compromise. In the immediate postoperative period, maintaining a patent airway is essential to prevent complications such as airway obstruction, hypoxia, and respiratory distress, which are critical in ensuring the client's safety and recovery.
