A nurse is assessing an older adult client who is receiving digoxin. The nurse should recognize that which of the following findings is a manifestation of digoxin toxicity?
Ataxia
Anorexia
Photosensitivity
Jaundice
The Correct Answer is B
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 C
Explanation
Choice A reason: "I'll be sure to eat more foods with vitamin K." is not the correct statement. Vitamin K is a nutrient that helps the blood to clot. Warfarin is an anticoagulant that inhibits the action of vitamin K and prevents the formation of blood clots. Eating more foods with vitamin K can counteract the effect of warfarin and increase the risk of thrombosis. The client should maintain a consistent intake of vitamin K and avoid sudden changes in their diet.
Choice B reason: "I'll take aspirin for my headaches." is not the correct statement. Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) that inhibits platelet aggregation and prolongs bleeding time. Taking aspirin with warfarin can increase the risk of bleeding and bruising. The client should avoid taking any NSAIDs without consulting their provider. The client should use acetaminophen or other non-NSAID pain relievers for their headaches.
Choice C reason: "I'll use my electric razor for shaving." is the correct statement. Using an electric razor for shaving can reduce the risk of cuts and bleeding. The client should avoid using sharp objects or instruments that can cause injury or trauma. The client should also use a soft toothbrush and floss gently to prevent bleeding gums.
Choice D reason: "It's okay to have a couple of glasses of wine with dinner each evening." is not the correct statement. Alcohol can interact with warfarin and affect its metabolism and effectiveness. Drinking alcohol with warfarin can either increase or decrease the blood levels of warfarin and alter the international normalized ratio (INR), which is a measure of the blood's clotting ability. The client should limit their alcohol intake and monitor their INR regularly.
Correct Answer is B
Explanation
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.
