The nurse is caring for a diabetic client who had a Coronary Angiography two hours ago. Which of the following orders should the nurse question?
Have client lay in bed flat for 4 hours
Monitor site for bleeding and hematoma formation
Administer metformin
Administer Aspirin
The Correct Answer is C
A. Having the client lay flat for 4 hours is appropriate. After coronary angiography, bed rest is required to prevent bleeding from the arterial puncture site, especially if a femoral approach was used.
B. Monitoring the site for bleeding and hematoma formation is correct. Bleeding is a potential complication, and frequent assessment of the catheter insertion site is necessary.
C. Administering metformin should be questioned. Metformin is contraindicated within 48 hours of receiving contrast dye because of the risk of lactic acidosis, especially in clients with impaired renal function.
D. Administering aspirin is appropriate. Aspirin is commonly prescribed to prevent clot formation after a coronary procedure.

Correct Answer is A
Explanation
A. Delivering a continuous flow of air pressure to keep the airway open is correct. CPAP (Continuous Positive Airway Pressure) prevents airway collapse during sleep, allowing for uninterrupted breathing and oxygenation.
B. Reducing daytime sleepiness is a benefit of CPAP use, but it is not its primary purpose—it is a secondary effect of improved oxygenation and sleep continuity.
C. Improving sleep quality also occurs with CPAP therapy, but this is an outcome rather than the primary purpose.
D. Promoting weight loss is not the function of CPAP therapy, though weight loss can help reduce OSA severity.
Correct Answer is D
Explanation
A. Checking blood pressure is important but does not confirm a myocardial infarction. Hypotension or hypertension may be present, but they are not definitive diagnostic tools.
B. Auscultating heart tones can help assess for murmurs or extra sounds, but it cannot diagnose a myocardial infarction.
C. Radiating pain to the left arm is a classic symptom, but not all clients experience it, and its absence does not rule out an MI.
D. Performing a 12-lead ECG is the most important diagnostic tool for identifying myocardial infarction. It provides real-time evidence of ischemic changes, such as ST-segment elevation or depression, confirming or ruling out an MI.
