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 is admitted with Atrial Fibrillation and is administered amiodarone (Cordarone). What therapeutic response should the nurse anticipate?

• A. Conversion of irregular heart rate to regular heart rhythm
• B. Pulse oximetry readings within normal range during activity
• C. Peripheral pulse points with adequate capillary refill
• D. Increase in exercise tolerance without shortness of breath

Correct answer: A

Rationale: The correct answer is A: Conversion of irregular heart rate to regular heart rhythm. Amiodarone is a medication commonly used to restore and maintain normal heart rhythm in clients with atrial fibrillation. It works by slowing down the electrical signals in the heart, helping to regulate the heartbeat. Choices B, C, and D are incorrect because they do not directly relate to the therapeutic response expected from administering amiodarone in a client with atrial fibrillation. Pulse oximetry readings, peripheral pulses, capillary refill, and exercise tolerance are important assessments but are not the primary therapeutic goal of using amiodarone in this situation.

4. 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.

5. The nurse is preparing to administer a tuberculin skin test (TST). Which area of the body is the preferred site for this injection?

• A. Deltoid muscle
• B. Inner forearm
• C. Abdomen
• D. Thigh

Correct answer: B

Rationale: The inner forearm is the preferred site for administering a tuberculin skin test (TST) due to its easy accessibility, minimal hair interference, and good visibility of the injection site, allowing for accurate interpretation of the test results. The deltoid muscle, abdomen, and thigh are not preferred sites for a TST as they may not provide the optimal conditions required for the test. The deltoid muscle is commonly used for intramuscular injections, the abdomen may have varying subcutaneous fat thickness affecting the test, and the thigh may not provide the necessary visibility for accurate reading.
