1. Which client is at greatest risk for coronary artery disease?

A. A 32-year-old female with mitral valve prolapse who quit smoking 10 years ago.
B. A 43-year-old male with a family history of CAD and a cholesterol level of 158 (8.8 mmol/L).
C. A 56-year-old male with an HDL of 60 (3.3 mmol/L) who takes atorvastatin.
D. A 65-year-old female who is obese with an LDL of 188 (10.4 mmol/L).

Correct answer: D

Rationale: The 65-year-old female who is obese with a high LDL level of 188 (10.4 mmol/L) is at the greatest risk for coronary artery disease. Obesity and high LDL cholesterol levels are significant risk factors for developing coronary artery disease. While factors like mitral valve prolapse (choice A) and a family history of CAD (choice B) can contribute to the risk, they are not as significant as obesity and high LDL levels. Choice C, a 56-year-old male with high HDL and taking atorvastatin, is actually at lower risk due to the high HDL levels and being on statin therapy, which helps reduce cholesterol levels and lower the risk of coronary artery disease.

2. A client who was involved in a motor vehicle collision is admitted with a fractured left femur that is immobilized using a fracture traction splint in preparation for an open reduction internal fixation (ORIF). The nurse determines that the client's distal pulses are diminished in the left foot. Which intervention should the nurse implement?

A. Verify pedal pulses using a Doppler pulse device
B. Evaluate the application of the splint to the left leg
C. Offer ice chips and clear oral liquids
D. Monitor the left leg for pain, pallor, paresthesia, paralysis, pressure

Correct answer: B

Rationale: Evaluating the application of the splint is the priority as it ensures it is not too tight, which could impair circulation and exacerbate the diminished pulses. Verifying pedal pulses with a Doppler pulse device may be indicated but does not directly address the immediate concern of proper splint application. Offering ice chips and clear oral liquids would not address the issue of diminished distal pulses. Monitoring the left leg for pain, pallor, paresthesia, paralysis, and pressure is important but would not directly address the cause of the diminished pulses in this scenario.

3. A client has just had a central line catheter placed that is specific for hemodialysis. What is the most appropriate action by the nurse?

A. Use the catheter for the next laboratory blood draw.
B. Monitor the central venous pressure through this line.
C. Access the line for the next intravenous medication.
D. Place a heparin or heparin/saline dwell after hemodialysis.

Correct answer: D

Rationale: The most appropriate action for the nurse after a central line catheter placement for hemodialysis is to place a heparin or heparin/saline dwell after hemodialysis treatment. This helps prevent clot formation in the line and maintain patency for future use. Using the catheter for blood draws is not recommended as it may increase the risk of infection. Monitoring central venous pressure is not indicated with this type of catheter. Accessing the line for medications is also not recommended to prevent complications and ensure the line is solely used for hemodialysis purposes.

4. A healthcare professional has a prescription to collect a 24-hour urine specimen from a client. Which of the following measures should the healthcare professional take during this procedure?

A. Keeping the specimen chilled
B. Saving the first urine specimen collected at the start time
C. Discarding the last voided specimen at the end of the collection time
D. Asking the client to void, discarding the specimen, and noting the start time

Correct answer: D

Rationale: The correct answer is asking the client to void, discarding the specimen, and noting the start time. During a 24-hour urine collection, the first voided urine is discarded to ensure the test starts with an empty bladder. The specimen should be kept chilled, not at room temperature, to prevent bacterial growth. The last voided specimen is not discarded because it contributes to the total volume collected, so choice C is incorrect. Discarding the specimen and noting the start time is essential for accurate results in a timed quantitative determination like a 24-hour urine collection.

5. What is a key intervention for a patient with diabetic ketoacidosis (DKA)?

A. Administering insulin
B. Administering IV fluids
C. Administering oral glucose
D. Administering oral fluids

Correct answer: A

Rationale: Administering insulin is a crucial intervention for a patient with diabetic ketoacidosis (DKA) because it helps in managing hyperglycemia and ketosis by promoting the uptake of glucose by cells and inhibiting the production of ketones. IV fluids are necessary to correct dehydration and electrolyte imbalances commonly seen in DKA but are not the primary treatment for the condition. Administering oral glucose would exacerbate hyperglycemia in a patient with DKA, while administering oral fluids alone would not effectively address the underlying metabolic disturbances seen in DKA.
