The nurse observed that a client with diabetic ketoacidosis is experiencing abnormally deep, regular, and rapid respirations. How would the nurse document this observation in the medical record?
Bradypnea
Kussmaul's respirations
Cheyne-Stokes respirations
Biot's respirations
The Correct Answer is B
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 C
Explanation
Choice A reason: Metabolic alkalosis is a condition where the pH and the HCO3- are both elevated, indicating a loss of acids or a gain of bases in the body. This is not the case for this patient, as his HCO3- is within the normal range of 22 to 26 mEq/L.
Choice B reason: Respiratory acidosis is a condition where the pH and the PaCO2 are both low, indicating a retention of carbon dioxide in the lungs due to hypoventilation. This is not the case for this patient, as his pH is high and his PaCO2 is low.
Choice C reason: Respiratory alkalosis is a condition where the pH and the PaCO2 are both high, indicating a loss of carbon dioxide in the lungs due to hyperventilation. This is the case for this patient, as his pH is above the normal range of 7.35 to 7.45 and his PaCO2 is below the normal range of 35 to 45 mm Hg. This condition is uncompensated, as his HCO3- is within the normal range and has not changed to counteract the pH imbalance.
Choice D reason: Metabolic acidosis is a condition where the pH and the HCO3- are both low, indicating a gain of acids or a loss of bases in the body. This is not the case for this patient, as his pH is high and his HCO3- is within the normal range.
Correct Answer is D
Explanation
Choice A reason: This is incorrect because the adrenal gland is not involved in the thirst mechanism. The adrenal gland is responsible for producing hormones such as cortisol, aldosterone, and adrenaline, which regulate stress response, blood pressure, and metabolism.
Choice B reason: This is incorrect because the cerebral cortex is not involved in the thirst mechanism. The cerebral cortex is the outer layer of the brain that is responsible for higher cognitive functions such as memory, language, and reasoning.
Choice C reason: This is incorrect because the pituitary gland is not directly involved in the thirst mechanism. The pituitary gland is a small gland at the base of the brain that produces hormones that control growth, reproduction, and metabolism. However, the pituitary gland does secrete antidiuretic hormone (ADH), which is regulated by the hypothalamus and affects water balance in the body.
Choice D reason: This is correct because the hypothalamus is the location of the thirst mechanism. The hypothalamus is a part of the brain that regulates many bodily functions such as temperature, appetite, sleep, and emotions. The hypothalamus also monitors the blood osmolarity and triggers the sensation of thirst when the blood is too concentrated.
