The registered nurse reviews the result of the arterial blood gas values with the licensed practical nurse and tells the LPN that the client has respiratory acidosis. The LPN would expect to note which of the following on the laboratory result report?
pH 7.50, PCO2 30 mmHg
pH 7.45, PCO2 52 mmHg
pH 7.25, PCO2 50 mmHg
pH 7.35, PCO2 40 mmHg
The Correct Answer is C
Choice A reason: This is incorrect because this represents respiratory alkalosis, not acidosis. Respiratory alkalosis is characterized by a high pH and a low PCO2.
Choice B reason: This is incorrect because this represents a mixed disorder, not a pure respiratory acidosis. A mixed disorder occurs when both the pH and the PCO2 are abnormal, but in opposite directions.
Choice C reason: This is correct because this represents respiratory acidosis. Respiratory acidosis is characterized by a low pH and a high PCO2.
Choice D reason: This is incorrect because this represents normal values, not respiratory acidosis. Normal values for pH and PCO2 are 7.35 to 7.45 and 35 to 45 mmHg, respectively.

Correct Answer is B
Explanation
Choice A reason: This is incorrect because bradypnea is a term for slow breathing, usually less than 12 breaths per minute. The client is breathing rapidly, not slowly.
Choice B reason: This is correct because Kussmaul's respirations are a type of breathing pattern that is deep, regular, and rapid, usually more than 20 breaths per minute. Kussmaul's respirations are a sign of metabolic acidosis, which occurs in diabetic ketoacidosis due to the accumulation of ketones in the blood. The client is trying to exhale the excess carbon dioxide and lower the acidity of the blood.
Choice C reason: This is incorrect because Cheyne-Stokes respirations are a type of breathing pattern that is irregular, with periods of apnea (no breathing) alternating with periods of rapid breathing. Cheyne-Stokes respirations are a sign of cerebral dysfunction, such as stroke, brain injury, or coma.
Choice D reason: This is incorrect because Biot's respirations are a type of breathing pattern that is irregular, with periods of apnea (no breathing) interspersed with periods of normal breathing. Biot's respirations are a sign of brainstem damage, such as meningitis, encephalitis, or head trauma.
Correct Answer is A
Explanation
Choice A reason: Renal failure can cause hyperkalemia because the kidneys are unable to excrete excess potassium from the body. This can lead to high levels of potassium in the blood, which can affect the heart and muscles.
Choice B reason: Diarrhea can cause hypokalemia, not hyperkalemia, because it can lead to loss of potassium from the gastrointestinal tract. This can result in low levels of potassium in the blood, which can also affect the heart and muscles.
Choice C reason: Blood transfusion can cause hyperkalemia if the blood is old or hemolyzed, meaning that the red blood cells have broken down and released potassium into the plasma. This can increase the potassium levels in the recipient's blood.
Choice D reason: Diaphoresis, or sweating, can cause hypokalemia, not hyperkalemia, because it can lead to loss of potassium from the skin. This can also lower the potassium levels in the blood.
