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 D
Explanation
D. 0.9% sodium chloride (0.9% NaCl): This solution, also known as normal saline, is isotonic and contains the same concentration of sodium as extracellular fluid. It is the most appropriate choice for initial fluid resuscitation in hypovolemia due to severe bleeding because it rapidly expands intravascular volume, replaces sodium losses, and helps restore circulating blood volume.
A. This solution contains dextrose (glucose) and a small amount of sodium chloride. It provides some glucose for energy but has a lower sodium concentration compared to isotonic solutions like normal saline. While it may be used in certain situations, such as to provide maintenance fluids or correct mild dehydration, it is not the first choice for fluid resuscitation in hypovolemia due to severe bleeding because it does not adequately replace lost volume.
B. 3% sodium chloride (3% NaCl): This solution is hypertonic and has a high sodium concentration. It is not typically used for initial fluid resuscitation in hypovolemia due to severe bleeding. Hypertonic saline solutions like 3% NaCl are more commonly used in specific situations such as severe hyponatremia or cerebral edema.
C. 5% dextrose in water (D5W): This solution contains only dextrose and water and is isotonic until the dextrose is metabolized, after which it becomes hypotonic. D5W is not suitable for fluid resuscitation in hypovolemia due to severe bleeding because it does not provide adequate sodium or volume replacement.
Correct Answer is A
Explanation
A. Directly asking the client how they learn best is a straightforward and effective approach for assessing their learning style preference. This allows the client to self-report their preferences, which can provide valuable insight into their preferred learning modalities, such as visual, auditory, or kinesthetic learning.
B. While assisting the client in learning skills from simple to complex can provide valuable information about their current level of understanding and skill mastery, it may not directly assess their learning style preference. This approach focuses more on the progression of learning rather than the client's preferred learning modalities.
C. Observing the client's interactions with others can provide some clues about their communication style and social preferences but may not necessarily directly assess their learning style preference. Learning style preference encompasses how individuals prefer to receive and process information, which may not be fully captured through social interactions alone.
D. Asking the client to read from a brochure primarily assesses their ability to process written information and may provide some insight into their literacy skills. However, it does not necessarily assess their preferred learning style, as individuals may have different preferences for how they prefer to receive and process information beyond reading.
