Extract:
Question 1 of 5
What is the primary purpose of using a CPAP machine for the treatment of obstructive sleep apnea (OSA)?
Correct Answer: A
Rationale: Delivering a continuous flow of air pressure to keep the airway open is correct. CPAP prevents airway collapse during sleep, allowing for uninterrupted breathing and oxygenation. Reducing daytime sleepiness, improving sleep quality, and promoting weight loss are benefits but not the primary purpose.
Question 2 of 5
The nurse is providing education to a client on ways to prevent the development of a pulmonary embolism. Which of the following statements would require further teaching?
Correct Answer: A
Rationale: Crossing the legs increases the risk of venous stasis and clot formation, requiring further teaching. Quitting smoking, staying hydrated, and exercising are appropriate preventive measures.
Question 3 of 5
Why are small, frequent meals recommended for patients with Chronic Obstructive Pulmonary Disease (COPD)?
Correct Answer: D
Rationale: Small, frequent meals reduce abdominal distention and diaphragm pressure, preventing dyspnea. Caloric intake, social interaction, and balanced diet are secondary considerations.
Question 4 of 5
A client with a diagnosis of heart failure is admitted to the cardiac unit. Which intervention should the nurse complete first?
Correct Answer: C
Rationale: Auscultating the lung and heart sounds is correct. In heart failure, pulmonary congestion and fluid overload can lead to respiratory distress. Immediate assessment for crackles, wheezing, or abnormal heart sounds evaluates for acute decompensation. Drawing a BMP, obtaining a health history, and assessing pulse and temperature are important but secondary to assessing for immediate respiratory or cardiac compromise.
Question 5 of 5
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?
Correct Answer: C
Rationale: 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. Having the client lay flat for 4 hours is appropriate to prevent bleeding from the arterial puncture site. Monitoring the site for bleeding and hematoma formation is necessary to detect complications. Administering aspirin is appropriate to prevent clot formation post-procedure.
