Nursing Elites

1. The nurse is preparing to administer a subcutaneous injection of heparin. What is the correct angle of insertion?

• A. 15 degrees
• B. 30 degrees
• C. 45 degrees
• D. 90 degrees

Correct answer: C

Rationale: The correct angle of insertion for a subcutaneous injection, such as heparin, is 45 degrees. This angle is appropriate as it helps to ensure proper delivery of the medication into the subcutaneous tissue. Option A (15 degrees) is too shallow for a subcutaneous injection and may result in the medication being deposited into the muscle. Option B (30 degrees) is also too shallow for subcutaneous injections. Option D (90 degrees) is used for intramuscular injections, not subcutaneous injections.

2. The nurse is assessing a client with congestive heart failure who is receiving furosemide (Lasix). Which laboratory value should the nurse monitor closely?

• A. Sodium level
• B. Potassium level
• C. Calcium level
• D. Chloride level

Correct answer: B

Rationale: The correct answer is B: Potassium level. Furosemide is a loop diuretic that can cause potassium loss, leading to hypokalemia. Monitoring the potassium level is crucial to prevent complications such as cardiac arrhythmias. Sodium level (choice A) is not typically affected by furosemide. Calcium level (choice C) and chloride level (choice D) are also not the primary focus of monitoring when a client is on furosemide for heart failure.

3. A client with a history of chronic obstructive pulmonary disease (COPD) is admitted with shortness of breath. What is the priority nursing intervention?

• A. Administer a high-flow oxygen mask.
• B. Position the client in a high-Fowler's position.
• C. Provide a high-carbohydrate diet.
• D. Encourage the client to cough and deep breathe.

Correct answer: B

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 breathing by reducing respiratory effort. Administering a high-flow oxygen mask (Choice A) may be necessary but is not the priority intervention. Providing a high-carbohydrate diet (Choice C) is not directly related to managing acute shortness of breath in COPD. Encouraging the client to cough and deep breathe (Choice D) is helpful for airway clearance but is not the priority intervention when the client is in distress with acute shortness of breath.

4. A client who has just been diagnosed with tuberculosis (TB) is being discharged home. Which instruction is most important for the nurse to provide?

• A. Avoid close contact with others until treatment is complete
• B. Take all prescribed medications as directed
• C. Schedule a follow-up appointment with the healthcare provider
• D. Wear a mask when in public places

Correct answer: B

Rationale: The correct answer is B: 'Take all prescribed medications as directed.' This instruction is the most important because adherence to the prescribed medication regimen is crucial in treating tuberculosis effectively and preventing the development of drug-resistant TB. While choice A is important for infection control, ensuring treatment adherence through proper medication intake takes precedence. Choice C is also essential for monitoring progress but is not as critical as ensuring medication compliance. Choice D is relevant for preventing transmission but is not as crucial as ensuring proper treatment by taking medications as directed.

5. The nurse is assessing a client with a suspected diagnosis of deep vein thrombosis (DVT). Which clinical sign is most indicative of DVT?

• A. Redness and warmth over the affected area
• B. Decreased peripheral pulses
• C. Cyanosis of the toes
• D. Muscle cramps in the calf

Correct answer: A

Rationale: Corrected Rationale: Redness and warmth over the affected area are classic signs of inflammation, which commonly occur in deep vein thrombosis (DVT) due to the obstruction of blood flow. These symptoms result from the body's inflammatory response to the blood clot. Choices B, C, and D are less indicative of DVT. Decreased peripheral pulses may occur in arterial insufficiency rather than DVT. Cyanosis of the toes indicates decreased oxygenation and is more characteristic of arterial issues. Muscle cramps in the calf are nonspecific and can be caused by various conditions, not solely DVT.
