For an arterial blood gas (ABG) to have full compensation, which of the following statements is correct?
pCO2 and pHCO3 and pH are abnormal but the pa02 remains between 80-100 mmHg
arterial pH & pCO2 are abnormal but the pHCO3 is starting to change
pCO2, pHCO3 and pH have adjusted in expected range in 72 hours
arterial pH is between 7.35-7.45 and the pCO2 & pO2 are abnormal
The Correct Answer is C
C. Full compensation typically occurs within 2 to 3 days (approximately 72 hours) after the onset of an acid-base disturbance. During full compensation, the primary acid-base disorder (e.g., respiratory acidosis or alkalosis, metabolic acidosis or alkalosis) is still present, but the compensatory mechanisms have effectively brought the pH, pCO2, and bicarbonate (pHCO3) levels back towards normal range.
A. Full compensation occurs when both the primary disorder (respiratory or metabolic) and the compensatory mechanism (renal or respiratory) are functioning to return the pH towards normal. In this option, while the pO2 is within the normal range, the pH, pCO2, and bicarbonate (pHCO3) are all abnormal, indicating an ongoing imbalance.
B. Full compensation occurs when all components of the ABG are within or approaching normal range, indicating that the body's compensatory mechanisms have effectively counteracted the primary acid- base disturbance. In this option, the bicarbonate (pHCO3) is mentioned as starting to change, indicating incomplete compensation.
D. While the pH is within the normal range, both the pCO2 and pO2 are abnormal, indicating a primary respiratory disturbance. In the case of full compensation, the pH, pCO2, and bicarbonate (pHCO3) levels would all be within or approaching normal range, indicating that the compensatory mechanisms have effectively counteracted the primary acid-base disturbance.

Correct Answer is C
Explanation
C. Excessive noise in the hospital environment, including alarms, conversations, and equipment noises, can disrupt sleep and negatively impact sleep quality. Therefore, limiting unnecessary noise on the unit is a crucial nursing intervention for improving sleep quality in the acute care setting. This may involve implementing quiet hours, reducing unnecessary conversations and activities during nighttime hours, and using noise-reducing strategies such as earplugs or white noise machines.
A. While providing a bedtime snack may help alleviate hunger and promote comfort, especially if the client is on a restricted diet or experiencing appetite changes, it may not directly address factors affecting sleep quality. Additionally, consuming food close to bedtime may not be suitable for all patients, especially those with dietary restrictions or certain medical conditions. Therefore, while a bedtime snack may be beneficial in some cases, it may not be the most important intervention for improving sleep quality in the acute care setting.
B. Pulling curtains around the bed can help create a sense of privacy and reduce visual distractions, which may contribute to a more conducive sleep environment. Enhanced privacy can also promote relaxation and feelings of security, potentially improving sleep quality. However, while privacy curtains can mitigate some external disturbances, they may not completely eliminate factors that affect sleep, such as noise or light.
D. Providing a backrub can promote relaxation, relieve tension, and enhance comfort, which may contribute to improved sleep quality for some patients. Massage therapy has been shown to reduce stress and promote relaxation, potentially facilitating better sleep. However, while backrubs can be a beneficial adjunct to promoting relaxation and comfort, they may not address all factors that affect sleep quality in the acute care setting.
Correct Answer is D
Explanation
D. It is important to recognize and respect the client's natural sleep patterns, especially considering their age and current health status. Napping during the day can be a normal and beneficial behavior for older adults, helping to replenish energy levels and promote overall well-being. As long as the client's napping does not interfere with their ability to sleep at night or their daily activities, no intervention may be necessary.
A. Encouraging the client to stay awake during the day may not be appropriate, especially considering the client's age and natural sleep patterns. Older adults often experience changes in their sleep-wake cycle, including more frequent napping during the day.
B. Physical activity is important for maintaining mobility and overall health but substituting physical therapy for one of the client's usual nap times may not be feasible or beneficial. The client's need for rest and sleep should be respected, especially if they are experiencing fatigue or illness.
C. Prescribing a sleeping pill for the client may not be appropriate, especially if they are already napping during the day. Sleep medications can have side effects, including drowsiness, confusion, and increased risk of falls, particularly in older adults.
