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
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.
Correct Answer is D
Explanation
Choice A reason: Having the client gently blow clots from his nose every 5 min is an incorrect action, because it can increase the bleeding and trauma to the nasal mucosa. The client should avoid blowing or picking his nose.
Choice B reason: Instructing the client to sit with his head hyperextended is an incorrect action, because it can cause the blood to drain into the throat and increase the risk of aspiration or vomiting. The client should sit with his head tilted forward.
Choice C reason: Applying ice compresses to the back of the client’s neck is an incorrect action, because it has no effect on the bleeding site. The nurse should apply ice compresses to the bridge of the nose or the cheeks to constrict the blood vessels and reduce the bleeding.
Choice D reason: Pinching the soft portion of the client’s nose for 10 min is a correct action, because it applies direct pressure to the bleeding site and allows clot formation. The nurse should instruct the client to breathe through his mouth and avoid swallowing the blood.
