Nursing Elites

1. Which of the following blood tests should be performed before a blood transfusion?

• A. Prothrombin and coagulation time
• B. Blood typing and cross-matching
• C. Bleeding and clotting time
• D. Complete blood count (CBC) and electrolyte levels

Correct answer: B

Rationale: Before administering a blood transfusion, it is crucial to perform blood typing and cross-matching to ensure compatibility between the donor's blood and the recipient's blood. This process helps prevent adverse reactions such as transfusion reactions, which can be life-threatening. Prothrombin and coagulation time, bleeding and clotting time, as well as CBC and electrolyte levels are important tests in other clinical contexts, but for blood transfusions, blood typing and cross-matching are essential to ensure patient safety.

2. When providing discharge teaching for a group of clients, a nurse should recommend a referral to a dietitian for which client?

• A. A client who has a prescription for warfarin and states, 'I will need to limit how much spinach I eat.'
• B. A client who has gout and states, 'I can continue to eat anchovies on my pizza.'
• C. A client who has a prescription for spironolactone and states, 'I will reduce my intake of foods that contain potassium.'
• D. A client who has osteoporosis and states, 'I'll plan to take my calcium carbonate with a full glass of water.'

Correct answer: B

Rationale: The correct answer is the client who has gout and states, 'I can continue to eat anchovies on my pizza.' Gout is a condition that requires dietary modifications to manage symptoms. Anchovies are high in purines, which can exacerbate gout symptoms. Therefore, a referral to a dietitian is essential to provide appropriate dietary guidance for a client with gout. Clients on warfarin may need to monitor their vitamin K intake, particularly from foods like spinach. Clients taking spironolactone should be cautious about potassium-rich foods. Clients with osteoporosis should be educated on the proper administration of calcium supplements but do not necessarily need a dietitian referral for this specific statement.

3. Which of the following procedures always requires surgical asepsis?

• A. Vaginal instillation of conjugated estrogen
• B. Urinary catheterization
• C. Nasogastric tube insertion
• D. Colostomy irrigation

Correct answer: B

Rationale: Surgical asepsis, which involves maintaining a sterile field and preventing contamination in a surgical setting, is required for urinary catheterization as it involves entering a sterile body cavity. Vaginal instillation of conjugated estrogen, nasogastric tube insertion, and colostomy irrigation do not always require surgical asepsis as they involve different levels of sterility and infection control measures.

4. Why is a precise amount of oxygen necessary for a patient with COPD to prevent which complication?

• A. Cardiac arrest related to increased partial pressure of carbon dioxide in arterial blood (PaCO2)
• B. Circulatory overload due to hypervolemia
• C. Respiratory excitement
• D. Inhibition of the respiratory hypoxic stimulus

Correct answer: D

Rationale: In patients with COPD, the respiratory drive is often stimulated by low oxygen levels. Administering too much oxygen can inhibit this hypoxic drive, leading to respiratory depression and potential respiratory failure. Therefore, it is crucial to carefully regulate the oxygen therapy to prevent the inhibition of the respiratory hypoxic stimulus in COPD patients.

5. A healthcare professional in the emergency department is assessing a client who has a suspected flail chest. Which of the following findings should the professional not expect?

• A. Bradycardia
• B. Cyanosis
• C. Hypotension
• D. Dyspnea

Correct answer: A

Rationale: Bradycardia is not typically associated with a flail chest. Flail chest is characterized by paradoxical chest wall movement, respiratory distress, and hypoxia, but it does not usually cause bradycardia. The other options, such as cyanosis (bluish discoloration of the skin due to poor oxygenation), hypotension (low blood pressure), and dyspnea (difficulty breathing), are commonly seen in patients with flail chest due to the underlying respiratory compromise.
