A nurse is teaching a client who has a new prescription for simvastatin. Which of the following instructions should the nurse include?
You should take the medication in the morning.
You should avoid grapefruit juice.
You should monitor for ringing in the ears.
You should expect brown-colored urine.
The Correct Answer is B
Choice A reason: Taking the medication in the morning is not the correct instruction. Simvastatin is a statin drug that lowers cholesterol levels by inhibiting the enzyme that produces cholesterol in the liver. The liver produces more cholesterol at night, so simvastatin is more effective when taken in the evening or at bedtime.
Choice B reason: Avoiding grapefruit juice is the correct instruction. Grapefruit juice can increase the blood levels of simvastatin and cause serious side effects such as muscle damage, liver damage, and kidney failure. Grapefruit juice inhibits the enzyme that metabolizes simvastatin in the intestine, leading to higher concentrations of the drug in the bloodstream.
Choice C reason: Monitoring for ringing in the ears is not the correct instruction. Ringing in the ears, or tinnitus, is not a common or serious side effect of simvastatin. However, some other medications that lower cholesterol, such as niacin and gemfibrozil, can cause tinnitus. The client should report any unusual or persistent symptoms to the prescriber.
Choice D reason: Expecting brown-colored urine is not the correct instruction. Brown-colored urine, or hematuria, is not a normal or expected side effect of simvastatin. However, it may indicate a serious condition such as rhabdomyolysis, which is a rare but life-threatening complication of statin therapy. Rhabdomyolysis is the breakdown of muscle tissue that releases a protein called myoglobin into the bloodstream. Myoglobin can damage the kidneys and cause brown-colored urine. The client should seek immediate medical attention if they notice any signs of rhabdomyolysis, such as muscle pain, weakness, fever, or dark urine.

Correct Answer is B
Explanation
Choice A reason: Ataxia is not a manifestation of digoxin toxicity, as it does not affect the coordination or balance of the client. Ataxia may be caused by other factors, such as cerebellar disorders, alcohol intoxication, or medication interactions.
Choice B reason: Anorexia is a manifestation of digoxin toxicity, as it affects the appetite and digestion of the client. Anorexia may be accompanied by nausea, vomiting, or abdominal pain, which are also signs of digoxin toxicity. Anorexia may lead to weight loss, dehydration, or electrolyte imbalance, which can worsen the condition of the client.
Choice C reason: Photosensitivity is not a manifestation of digoxin toxicity, as it does not affect the skin or the eyes of the client. Photosensitivity may be caused by other factors, such as sun exposure, allergies, or medication interactions.
Choice D reason: Jaundice is not a manifestation of digoxin toxicity, as it does not affect the liver or the bilirubin level of the client. Jaundice may be caused by other factors, such as liver disease, gallstones, or hemolysis.
Correct Answer is D
Explanation
Choice A reason: The nurse collects a urine specimen is an appropriate action, as it can help detect the presence of hemoglobinuria, which is a sign of hemolysis. Hemoglobinuria is the excretion of hemoglobin in the urine, which can cause the urine to appear red or brown.
Choice B reason: The nurse sends a blood specimen to the laboratory is an appropriate action, as it can help confirm the diagnosis of a hemolytic reaction and identify the cause. The laboratory can perform tests such as blood typing, cross-matching, direct antiglobulin test (DAT), and serum bilirubin.
Choice C reason: The nurse initiates an infusion of 0.9% sodium chloride is an appropriate action, as it can help maintain the client's fluid and electrolyte balance and prevent hypovolemic shock. 0.9% sodium chloride is the preferred solution for blood transfusion reactions, as it is isotonic and compatible with blood products.
Choice D reason: The nurse starts the transfusion of another unit of blood product is an inappropriate action, as it can worsen the client's condition and increase the risk of complications. The nurse should not resume the transfusion until the cause of the reaction is determined and the provider orders a new unit of blood product. The nurse should also return the unused blood product and tubing to the blood bank for analysis.
