Nursing Elites

1. 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.

2. While caring for a client's postoperative dressing, the nurse observes purulent wound drainage. Previously, the wound was inflamed and tender but without drainage. Which is the most important action for the nurse to take?

• A. Determine if the drainage has an unpleasant odor.
• B. Monitor the client's white blood cell count (WBC).
• C. Request a culture and sensitivity of the wound.
• D. Cleanse the wound with a sterile saline solution.

Correct answer: C

Rationale: Requesting a culture and sensitivity of the wound is the most crucial action in this scenario. This will help identify the specific organism causing the infection and determine its sensitivity to antibiotics, guiding appropriate antibiotic therapy. Option A is less critical as odor alone may not provide enough information about the type of infection. Monitoring the client's white blood cell count (WBC) in option B is important but not as immediate as obtaining a wound culture. Cleansing the wound with a sterile saline solution in option D is necessary but should follow after obtaining the culture results to ensure proper treatment.

3. The healthcare provider is assessing a client who has just undergone a thoracentesis. Which finding should be reported immediately?

• A. Diminished breath sounds on the affected side.
• B. Pain at the procedure site.
• C. Blood-tinged sputum.
• D. Shortness of breath.

Correct answer: D

Rationale: Shortness of breath should be reported immediately as it may indicate a pneumothorax, a potential complication of thoracentesis. Diminished breath sounds on the affected side, pain at the procedure site, and blood-tinged sputum are common findings post-thoracentesis and do not necessarily indicate immediate complications like a pneumothorax.

4. The nurse is assessing a client with hyperkalemia. Which finding is consistent with this electrolyte imbalance?

• A. Muscle weakness
• B. Decreased deep tendon reflexes
• C. Constipation
• D. Hypotension

Correct answer: A

Rationale: Muscle weakness is a common finding in clients with hyperkalemia. Hyperkalemia can lead to muscle weakness due to the effect of high potassium levels on muscle function. Decreased deep tendon reflexes (Choice B) are not typically associated with hyperkalemia; instead, hyperreflexia or increased reflexes may be observed. Constipation (Choice C) is not a common symptom of hyperkalemia. Hypotension (Choice D) is also not a typical finding in hyperkalemia; instead, hypertension or normal blood pressure may be present.

5. 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.
