Nursing Elites

1. The nurse is teaching a client with hypertension about lifestyle modifications. Which recommendation is most effective for lowering blood pressure?

• A. Increase intake of red meat
• B. Engage in regular physical activity
• C. Consume a high-sodium diet
• D. Limit fluid intake to 1 liter per day

Correct answer: B

Rationale: Engaging in regular physical activity is a highly effective recommendation for lowering blood pressure and improving overall cardiovascular health. Regular exercise helps to strengthen the heart, improve blood circulation, and manage weight, all of which contribute to reducing blood pressure levels. Choices A, C, and D are incorrect. Increasing intake of red meat can lead to higher saturated fat consumption, which is detrimental to heart health. Consuming a high-sodium diet can exacerbate hypertension by increasing blood pressure. Limiting fluid intake to 1 liter per day may lead to dehydration and is not a recommended approach for managing hypertension.

2. A client is admitted with a diagnosis of diabetic ketoacidosis (DKA). Which laboratory finding is most indicative of this condition?

• A. Serum glucose of 180 mg/dL
• B. Blood pH of 7.30
• C. Positive urine ketones
• D. Serum bicarbonate of 25 mEq/L

Correct answer: C

Rationale: The correct answer is C: Positive urine ketones. In diabetic ketoacidosis (DKA), the body breaks down fat for energy due to a lack of insulin, leading to ketone production. Positive urine ketones are a hallmark laboratory finding in DKA as they directly reflect the presence of ketosis. Choice A, serum glucose of 180 mg/dL, may be elevated in DKA, but it is not specific to this condition. Choice B, blood pH of 7.30, often shows acidosis in DKA, but urine ketones are more specific to the presence of ketosis. Choice D, serum bicarbonate of 25 mEq/L, would typically be low in DKA due to acidosis rather than elevated.

3. When reconstituted, how many milligrams are in each milliliter of solution?

• A. 300 mg/mL
• B. 350 mg/mL
• C. 450 mg/mL
• D. 400 mg/mL

Correct answer: D

Rationale: After reconstitution, the concentration of the cefazolin solution is 400 mg/mL. This calculation is derived by dividing the total milligrams in the vial (1000 mg) by the total volume after reconstitution (2.5 mL). Therefore, each milliliter of the solution contains 400 mg of cefazolin. Choices A, B, and C are incorrect as they do not match the correct calculation based on the information provided.

4. Which client is at the highest risk for developing pressure ulcers?

• A. A 50-year-old client with a fractured femur
• B. A 30-year-old client with diabetes mellitus
• C. A 65-year-old client with limited mobility
• D. A 70-year-old client with a history of stroke

Correct answer: C

Rationale: Clients with limited mobility are at the highest risk for developing pressure ulcers due to prolonged pressure on specific areas of the body. This constant pressure can lead to tissue damage and ultimately result in pressure ulcers. While age and medical conditions such as diabetes and a history of stroke can contribute to the risk of pressure ulcers, limited mobility is the most significant factor as it directly affects the ability to shift positions and relieve pressure on vulnerable areas of the body. Therefore, the 65-year-old client with limited mobility is at the highest risk compared to the other clients. The 50-year-old client with a fractured femur may have limited mobility due to the injury, but it is temporary and may not be as prolonged as chronic limited mobility. The 30-year-old client with diabetes mellitus and the 70-year-old client with a history of stroke are at risk for developing pressure ulcers, but their conditions do not directly impact their ability to shift positions and alleviate pressure like limited mobility does.

5. The nurse is assessing a client who has just received a blood transfusion. The client reports chills and back pain. What is the nurse's priority action?

• A. Slow the rate of transfusion.
• B. Administer an antipyretic.
• C. Stop the transfusion immediately.
• D. Notify the healthcare provider.

Correct answer: C

Rationale: The correct answer is C: Stop the transfusion immediately. Chills and back pain are indicative of a possible transfusion reaction, which is a critical situation. Stopping the transfusion is crucial to prevent further complications and ensure the client's safety. Slowing the rate of transfusion (Choice A) is not sufficient in this case as immediate action is required. Administering an antipyretic (Choice B) may help with fever but does not address the potential severe reaction. Notifying the healthcare provider (Choice D) can be done after stopping the transfusion, but the priority is to halt the infusion to prevent harm.
