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. This allows healthcare providers to quickly administer treatments without the need for repeated venipuncture, which can be beneficial in various medical situations where time and vein preservation are critical.
A. Peripheral intravenous saline locks are not typically used to accommodate highly irritating or hyperosmolar solutions. Saline locks are used to maintain venous access without continuous infusion, and they are generally used with isotonic solutions to prevent complications such as phlebitis or infiltration.
B. The access is not very reliable when used for drawing samples repeatedly.
D. While peripheral intravenous saline locks can be used for intermittent administration of IV antibiotics or other medications, they are not typically used for prolonged IV antibiotic administration.
Correct Answer is A
Explanation
A. This statement suggests that the client may have sleep-disordered breathing, such as obstructive sleep apnea, which can disrupt the client's sleep patterns and affect their overall sleep quality. The nurse may want to inquire further about the frequency and severity of the snoring, as well as any associated symptoms such as daytime fatigue or observed pauses in breathing during sleep.
B. This statement indicates that emotional stressors, such as arguments or conflicts, may impact the client's sleep patterns. The nurse may want to explore how often these conflicts occur and how they affect the client's ability to fall asleep or stay asleep. Additionally, the nurse may inquire about coping strategies or interventions that the client and their partner use to address conflicts and minimize their impact on sleep.
C. This statement suggests that the client experiences deep or heavy sleep, which may or may not be problematic depending on the context. While deep sleep can be indicative of good sleep quality, it may also raise concerns about the client's ability to awaken in the event of an emergency or the presence of a sleep disorder such as hypersomnia. The nurse may want to inquire further about the client's overall sleep duration, sleep latency, and any difficulties with waking up in the morning.
D. This statement suggests that the client may experience sleep talking, which is a common sleep phenomenon. While sleep talking itself is typically benign, it may indicate underlying sleep disturbances such as sleep fragmentation or abnormal sleep cycles. The nurse may want to ask additional questions to assess the frequency and content of the sleep talking, as well as any potential impacts on the client's sleep quality or daytime functioning.
