Nursing Elites

1. The client has chronic renal failure. What dietary modification is most important for this client?

• A. Increase protein intake
• B. Limit potassium-rich foods
• C. Increase sodium intake
• D. Encourage dairy products

Correct answer: B

Rationale: Limiting potassium-rich foods is crucial in chronic renal failure to prevent hyperkalemia, which can lead to cardiac complications. Excessive protein intake can increase the workload on the kidneys and may result in the accumulation of uremic toxins. Increasing sodium intake is generally discouraged in chronic renal failure due to its association with hypertension and fluid retention. Encouraging dairy products may not be suitable for all clients with chronic renal failure, as they are a significant source of phosphorus, which needs to be limited in renal failure to prevent mineral imbalances.

2. The nurse is preparing a client for discharge following a myocardial infarction. What should the nurse prioritize in the discharge instructions?

• A. Warning signs of a potential heart attack
• B. Importance of medication adherence
• C. Follow-up appointment details
• D. All of the above

Correct answer: D

Rationale: When preparing a client for discharge after a myocardial infarction, the nurse should prioritize providing comprehensive instructions. This includes educating the client about warning signs of a potential heart attack to recognize symptoms early, stressing the importance of medication adherence for optimal recovery and prevention of further cardiac events, and ensuring understanding of follow-up appointment details for ongoing monitoring and care. All these aspects are crucial in preventing complications and promoting the client's well-being. Therefore, selecting 'All of the above' as the correct answer is the most appropriate choice. Choices A, B, and C are all essential components of a holistic discharge plan for a client post-myocardial infarction.

3. 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.

4. What is the primary function of neutrophils?

• A. Heparin secretion
• B. Transport oxygen
• C. Phagocytotic action
• D. Antibody formation

Correct answer: C

Rationale: The correct answer is C: Phagocytotic action. Neutrophils are key components of the immune system, primarily involved in the phagocytosis of bacteria and other pathogens. Choice A, Heparin secretion, is incorrect as heparin is primarily secreted by mast cells and basophils. Choice B, Transport oxygen, is incorrect as this is mainly the function of red blood cells. Choice D, Antibody formation, is incorrect as antibody production is primarily carried out by B lymphocytes.

5. A client with a history of congestive heart failure is prescribed digoxin (Lanoxin). Which assessment is most important for the nurse to obtain before administering this medication?

• A. Blood pressure
• B. Heart rate
• C. Respiratory rate
• D. Oxygen saturation

Correct answer: B

Rationale: The correct answer is B: Heart rate. Before administering digoxin to a client with a history of congestive heart failure, the nurse must assess the client's heart rate. Digoxin can cause bradycardia, so monitoring the heart rate is crucial to prevent potential complications. Assessing blood pressure, respiratory rate, and oxygen saturation are important assessments but are not as directly influenced by digoxin as heart rate is in this scenario. Blood pressure can be affected by various factors, including dehydration or other medications. Respiratory rate and oxygen saturation are more related to respiratory function and gas exchange, which are not the primary concerns when administering digoxin to a client with heart failure.
