A nurse is reinforcing teaching with a client who has tuberculosis and a prescription for rifampin. The nurse should identify which of the following findings as a harmless and expected adverse effect of rifampin?

Red-orange discoloration of urine

Increased ecchymosis

Yellow appearance of the sclerae

Lack of energy

Answer and Explanation

The Correct Answer is A

Choice A reason: This is the correct finding, because rifampin is an antibiotic that can cause red-orange discoloration of urine, saliva, sweat, tears, and other body fluids. This is a harmless and expected adverse effect of rifampin, and does not indicate any damage to the kidneys or liver. The client should be informed about this effect and advised to wear soft contact lenses, as rifampin can stain them permanently.

Choice B reason: This is an incorrect finding, because increased ecchymosis, or bruising, is not a harmless or expected adverse effect of rifampin, but a sign of bleeding disorder or thrombocytopenia, which is a rare but serious complication of rifampin. Rifampin can interfere with the synthesis of vitamin K, which is essential for blood clotting, and cause bleeding problems. The client should report any signs of bleeding, such as ecchymosis, petechiae, hematuria, or epistaxis, to the provider.

Choice C reason: This is an incorrect finding, because yellow appearance of the sclerae, or jaundice, is not a harmless or expected adverse effect of rifampin, but a sign of liver damage or hepatitis, which is a rare but serious complication of rifampin. Rifampin can cause inflammation and injury to the liver cells, and impair the metabolism and excretion of bilirubin, which is a yellow pigment that accumulates in the skin and eyes when the liver is damaged. The client should report any signs of liver dysfunction, such as jaundice, dark urine, pale stools, or abdominal pain, to the provider.

Choice D reason: This is an incorrect finding, because lack of energy, or fatigue, is not a harmless or expected adverse effect of rifampin, but a sign of anemia or hypothyroidism, which are rare but serious complications of rifampin. Rifampin can cause hemolytic anemia, which is a condition that occurs when the red blood cells are destroyed faster than they are produced, and hypothyroidism, which is a condition that occurs when the thyroid gland produces insufficient thyroid hormone. The client should report any signs of anemia or hypothyroidism, such as fatigue, weakness, pallor, or cold intolerance, to the provider.

Correct Answer is B

Explanation

Choice A reason: This is an important data, but not the first one. The nurse should first assess the client's airway, breathing, and circulation, which are the priorities in any emergency situation.

Choice B reason: This is the correct data, because the nurse should first collect the respiratory rate to determine if the client has any signs of airway obstruction, inhalation injury, or respiratory distress, which are life-threatening complications of facial burns.

Choice C reason: This is a relevant data, but not the first one. The nurse should collect the presence of bowel sounds later, after ensuring the client's airway, breathing, and circulation are stable, to assess the client's gastrointestinal function and possible paralytic ileus.

Choice D reason: This is a significant data, but not the first one. The nurse should collect the level of pain later, after ensuring the client's airway, breathing, and circulation are stable, to provide adequate analgesia and comfort measures.

A. Respiratory alkalosis B. Metabolic acidosis C. Respiratory acidosis D. Metabolic alkalosis

Correct Answer is A

Explanation

Choice A reason: This is the correct imbalance, because respiratory alkalosis is a condition that occurs when the blood pH is high, the PaCO2 is low, and the HCO3 is normal or low. Respiratory alkalosis is caused by hyperventilation, which can result from anxiety, fever, pain, or mechanical ventilation.

Choice B reason: This is an incorrect imbalance, because metabolic acidosis is a condition that occurs when the blood pH is low, the PaCO2 is normal or low, and the HCO3 is low. Metabolic acidosis is caused by the accumulation of acids in the blood, which can result from diabetic ketoacidosis, renal failure, or lactic acidosis.

Choice C reason: This is an incorrect imbalance, because respiratory acidosis is a condition that occurs when the blood pH is low, the PaCO2 is high, and the HCO3 is normal or high. Respiratory acidosis is caused by hypoventilation, which can result from airway obstruction, chest injury, or narcotic overdose.

Choice D reason: This is an incorrect imbalance, because metabolic alkalosis is a condition that occurs when the blood pH is high, the PaCO2 is normal or high, and the HCO3 is high. Metabolic alkalosis is caused by the loss of acids from the blood, which can result from vomiting, gastric suction, or diuretic therapy.
