Nursing Elites

1. The nurse is administering an intradermal injection for a tuberculosis skin test. Which technique should the nurse use?

• A. Use a 25-gauge needle at a 90-degree angle
• B. Use a 27-gauge needle at a 15-degree angle
• C. Use a 22-gauge needle at a 45-degree angle
• D. Use a 20-gauge needle at a 90-degree angle

Correct answer: B

Rationale: An intradermal injection for a tuberculosis skin test should be administered using a 27-gauge needle at a 15-degree angle. This technique ensures that the medication is delivered into the dermis layer of the skin. Choice A is incorrect because a 25-gauge needle is too large for an intradermal injection. Choice C is incorrect as a 22-gauge needle is also too large and the angle is too steep for an intradermal injection. Choice D is incorrect as a 20-gauge needle is too large for an intradermal injection, and a 90-degree angle would not deliver the medication accurately into the dermis.

2. When caring for a client with acute respiratory distress syndrome (ARDS), why does the nurse elevate the head of the bed 30 degrees?

• A. To reduce abdominal pressure on the diaphragm
• B. To promote oxygenation by improving lung expansion
• C. To encourage use of accessory muscles for breathing
• D. To drain secretions and prevent aspiration

Correct answer: D

Rationale: Elevating the head of the bed in a client with acute respiratory distress syndrome (ARDS) is essential to drain secretions and prevent aspiration. This position helps facilitate the removal of secretions from the airways, reducing the risk of aspiration pneumonia. Choices A, B, and C are incorrect as the primary reason for elevating the head of the bed in ARDS is to assist with secretion drainage and prevent complications associated with aspiration.

3. A client with hyperparathyroidism is preparing for surgery. Which preoperative lab finding is most important to report?

• A. Elevated serum calcium.
• B. Decreased serum albumin.
• C. Elevated serum potassium.
• D. Elevated serum magnesium.

Correct answer: A

Rationale: The correct answer is A: Elevated serum calcium. In hyperparathyroidism, elevated calcium levels can lead to complications such as kidney stones, bone pain, and fractures. During surgery, high calcium levels can affect neuromuscular function, cardiac function, and blood clotting. Therefore, it is crucial to report elevated serum calcium levels preoperatively to prevent potential surgical complications. Choices B, C, and D are not directly associated with hyperparathyroidism and are less likely to impact the surgical outcome in this scenario.

4. The nurse is caring for a client with deep vein thrombosis (DVT) who is receiving anticoagulant therapy. Which intervention should the nurse implement to prevent complications?

• A. Elevate the affected leg
• B. Encourage early ambulation
• C. Perform frequent range-of-motion exercises
• D. Apply ice packs to the affected leg

Correct answer: A

Rationale: Elevating the affected leg is crucial in managing deep vein thrombosis (DVT) as it helps to reduce swelling and improve venous return. This intervention is essential for preventing complications such as pulmonary embolism. Encouraging early ambulation is generally beneficial for preventing DVT but is secondary to leg elevation. Performing range-of-motion exercises can be helpful for maintaining joint mobility but is not the priority intervention in this case. Applying ice packs to the affected leg is not recommended in DVT management as it can cause vasoconstriction and potentially worsen the condition.

5. A client recently started on warfarin therapy. What laboratory value is most important to monitor for this client?

• A. Platelet count
• B. Prothrombin time (PT)
• C. Creatinine level
• D. Blood urea nitrogen (BUN)

Correct answer: B

Rationale: Prothrombin time (PT) is the most important laboratory value to monitor for clients on warfarin therapy. PT helps determine how long it takes blood to clot and ensures the warfarin dose is within the therapeutic range to prevent either excessive bleeding or clotting. Monitoring platelet count is important for assessing the risk of bleeding, but PT is more specific to warfarin therapy. Creatinine level and BUN are indicators of kidney function and are not directly related to warfarin therapy.
