Nursing Elites

1. The nurse is caring for a 75-year-old male client who is beginning to form a decubitus ulcer at the coccyx. Which intervention will be most helpful in preventing further development of the decubitus ulcer?

• A. Encourage the client to eat foods high in protein
• B. Assess the client for daily range of motion exercises
• C. Teach the family how to perform sterile wound care
• D. Ensure the IV fluids are administered as prescribed

Correct answer: A

Rationale: Encouraging the client to eat foods high in protein is crucial in preventing further development of decubitus ulcers as high protein foods support tissue repair and skin integrity. Adequate protein intake is essential for wound healing. Assessing the client for daily range of motion exercises is important for preventing complications related to immobility, but it may not directly address the prevention of decubitus ulcers. Teaching the family how to perform sterile wound care is significant for wound management but may not be the most effective intervention to prevent further development of decubitus ulcers. Ensuring IV fluids are administered as prescribed is essential for maintaining hydration status but is not the most relevant intervention for preventing decubitus ulcers.

2. The practical nurse is preparing to administer a prescription for cefazolin (Kefzol) 600 mg IM every six hours. The available vial is labeled, 'Cefazolin (Kefzol) 1 gram,' and the instructions for reconstitution state, 'For IM use add 2 ml sterile water for injection. Total volume after reconstitution = 2.5 ml.' When reconstituted, how many milligrams are in each milliliter of solution?

• A. 400 mg/mL
• B. 500 mg/mL
• C. 450 mg/mL
• D. 350 mg/mL

Correct answer: A

Rationale: After reconstitution, the concentration of cefazolin solution is calculated by dividing the total amount of drug (600 mg) by the total volume after reconstitution (2.5 mL). This gives 600 mg / 2.5 mL = 240 mg/mL. However, the question asks for the concentration in each milliliter of solution after reconstitution, so we need to consider the final volume of 2.5 mL. Therefore, 240 mg/mL * 2.5 mL = 600 mg, which means each milliliter contains 240 mg of cefazolin. Therefore, after reconstitution, there are 400 mg of cefazolin in each milliliter of solution. Choices B, C, and D are incorrect as they do not accurately reflect the concentration after reconstitution.

3. The wife is observed shaving her husband's beard with a safety razor. What should the nurse do?

• A. Advise the wife to shave against the hair growth
• B. Teach the wife to keep the skin loose to avoid cuts
• C. Encourage the wife to continue shaving her husband
• D. Demonstrate the correct procedure to the wife

Correct answer: C

Rationale: In this situation, the nurse should encourage the wife to continue shaving her husband. The rationale behind this is that the wife is already performing the task, so abrupt interference may lead to potential harm or emotional distress. It is crucial for the nurse to carefully observe the situation and assess for any safety concerns. While teaching proper techniques (Choice B) is important, it can be addressed later in a non-critical manner to prevent skin irritation and injury. Advising to shave against the hair growth (Choice A) may cause skin irritation and cuts. Although demonstrating the correct procedure (Choice D) may be helpful, it is essential to consider the current dynamics and respect the wife's autonomy in caring for her husband.

4. A client with a diagnosis of myocardial infarction (MI) is prescribed nitroglycerin. What is the primary action of this medication?

• A. Increases heart rate
• B. Lowers blood pressure
• C. Dilates coronary arteries
• D. Reduces myocardial oxygen demand

Correct answer: C

Rationale: The correct answer is C: Nitroglycerin dilates coronary arteries, improving blood flow to the heart muscle. This helps increase oxygen supply to the heart tissue. Option A, 'Increases heart rate,' is incorrect because nitroglycerin does not directly affect heart rate. Option B, 'Lowers blood pressure,' is also incorrect as while nitroglycerin can lower blood pressure, its primary action in the context of MI is related to coronary artery dilation. Option D, 'Reduces myocardial oxygen demand,' is not the primary action of nitroglycerin in the treatment of myocardial infarction; its main action is to increase oxygen supply by dilating coronary arteries.

5. A client with a diagnosis of chronic heart failure is receiving digoxin. What is the most important assessment before administering this medication?

• A. Check blood pressure.
• B. Assess heart rate.
• C. Monitor respiratory rate.
• D. Measure oxygen saturation.

Correct answer: B

Rationale: The correct answer is to assess the heart rate. Before administering digoxin, it is essential to evaluate the heart rate as digoxin can cause bradycardia. While checking blood pressure, monitoring respiratory rate, and measuring oxygen saturation are important assessments in the care of a client with chronic heart failure, assessing the heart rate is particularly critical due to the medication's potential impact on heart rhythm.
