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 caring for a client with a chest tube after thoracic surgery. What is the most important assessment related to the chest tube?

• A. Ensure continuous bubbling in the water seal chamber
• B. Measure the amount of drainage every shift
• C. Keep the drainage system at the level of the chest
• D. Assess for subcutaneous emphysema around the insertion site

Correct answer: D

Rationale: The most important assessment related to a chest tube after thoracic surgery is to assess for subcutaneous emphysema around the insertion site. Subcutaneous emphysema can indicate air leakage from the pleural space, which can lead to serious complications such as a pneumothorax. Ensuring continuous bubbling in the water seal chamber is not the most critical assessment as it is a normal finding in a chest drainage system. While measuring the amount of drainage is important to monitor the client's condition, it is not as crucial as assessing for subcutaneous emphysema. Keeping the drainage system at the level of the chest helps maintain proper function but is not the most critical assessment in this scenario.

3. The nurse is providing care for a client with a draining postoperative wound infected with methicillin-resistant Staphylococcus aureus (MRSA). Which is the most important action for the nurse to take?

• A. Encourage increased oral fluids.
• B. Provide high-protein snacks.
• C. Change the wound dressing.
• D. Administer prescribed antibiotics.

Correct answer: D

Rationale: Administering prescribed antibiotics is crucial in treating MRSA infections. MRSA is a type of bacteria that is resistant to many antibiotics, including methicillin. Therefore, prompt administration of the appropriate antibiotics is essential to target the MRSA infection effectively. Encouraging increased oral fluids (Choice A) and providing high-protein snacks (Choice B) may be beneficial for overall recovery but are not the most important actions in treating an MRSA infection. Changing the wound dressing (Choice C) is important for wound care but does not directly address the infection caused by MRSA.

4. The nurse observes that a post-operative client's surgical wound has reddened edges and is oozing. What is the appropriate nursing action?

• A. Apply an antibiotic ointment
• B. Clean the wound with sterile saline
• C. Cover the wound with a sterile dressing
• D. Notify the surgeon immediately

Correct answer: D

Rationale: The correct action when a post-operative client's surgical wound has reddened edges and is oozing is to notify the surgeon immediately. Reddened, oozing wound edges can indicate an infection that requires prompt evaluation and intervention by the surgical team. Applying an antibiotic ointment (Choice A) without proper assessment and guidance can be inappropriate. Cleaning the wound with sterile saline (Choice B) and covering it with a sterile dressing (Choice C) may not address the potential infection adequately, and the client may require more specialized care that the surgeon can provide.

5. The nurse is caring for a client with chronic obstructive pulmonary disease (COPD) who is experiencing shortness of breath. What is the priority nursing intervention?

• A. Administer bronchodilator therapy as prescribed.
• B. Inhale the medication slowly while pressing down on the inhaler.
• C. Position the client in a high-Fowler's position.
• D. Increase the oxygen flow rate.

Correct answer: C

Rationale: The priority nursing intervention for a client with COPD experiencing shortness of breath is to position the client in a high-Fowler's position. This position helps improve lung expansion and ease breathing by maximizing chest expansion and allowing for better airflow. While administering bronchodilator therapy is important, positioning the client for improved breathing takes priority. Inhaling the medication slowly and pressing down on the inhaler is a correct technique for inhaler use but not the priority intervention. Increasing the oxygen flow rate may be needed, but adjusting the client's position to a high-Fowler's position is the priority to address the shortness of breath in COPD.
