What is the primary purpose of using a CPAP machine for the treatment of obstructive sleep apnea (OSA)?

To deliver a continuous flow of air pressure to keep the airway open

To reduce daytime sleepiness

To improve sleep quality

To promote weight loss

Answer and Explanation

The Correct Answer is A

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 B

Explanation

A. Weight gain is more commonly associated with right-sided heart failure due to fluid retention and peripheral edema, not left-sided heart failure.
B. Shortness of breath (dyspnea) is correct. Left-sided heart failure causes pulmonary congestion, leading to dyspnea, orthopnea, and pulmonary edema as blood backs up into the lungs.
C. Pulmonary embolism is not a direct manifestation of left-sided heart failure. While heart failure increases the risk of clot formation, a pulmonary embolism is a separate condition.
D. Anorexia is more common in right-sided heart failure, as systemic venous congestion can lead to gastrointestinal edema and poor appetite.

A. Encourage an increased intake of the client's favorite drink B. Continue to monitor daily weights and edema and document findings. C. Perform a head-to-toe assessment, including vital signs D. Check the record to determine code status

Correct Answer is C

Explanation

A. Encouraging increased fluid intake is incorrect. Clients with heart failure are at risk for fluid overload, and excessive fluid intake can worsen symptoms.
B. Simply monitoring and documenting findings is insufficient. A 2-pound weight gain in a short period suggests fluid retention and worsening heart failure, requiring further assessment and possible intervention.
C. Performing a head-to-toe assessment, including vital signs, is correct. The nurse should assess for worsening heart failure, including lung sounds (crackles), respiratory effort, blood pressure, and oxygen saturation, to determine if immediate interventions are needed.
D. Checking code status is not the priority. While knowing a client’s code status is important, the immediate concern is assessing for signs of fluid overload and potential decompensation.
