A patient with frequent tension headaches asks the nurse about over-the-counter remedies. The nurse knows that Excedrin combines which of the following active ingredients to address pain, inflammation, and increased vascular tone associated with headaches?
Aspirin, acetaminophen, and caffeine
Ibuprofen, naproxen, and caffeine
Aspirin, loratadine, and caffeine
Acetaminophen, naproxen, and loratadine
The Correct Answer is A
Choice A reason: This is correct. Excedrin contains a combination of aspirin, acetaminophen, and caffeine. Aspirin is a nonsteroidal anti-inflammatory drug (NSAID) that reduces pain, inflammation, and swelling. Acetaminophen is a pain reliever and a fever reducer. Caffeine is a central nervous system stimulant that enhances the pain-relieving function of aspirin and acetaminophen.
Choice B reason: This is incorrect. Ibuprofen and naproxen are both NSAIDs, but they are not the same as aspirin. They have different chemical structures and may have different effects and side effects. Caffeine is not an ingredient in ibuprofen or naproxen products.
Choice C reason: This is incorrect. Loratadine is an antihistamine that is used to treat allergies, not headaches. It does not have any pain-relieving or anti-inflammatory properties. Caffeine is not an ingredient in loratadine products.
Choice D reason: This is incorrect. Naproxen is an NSAID, but it is not the same as aspirin. It has a different chemical structure and may have different effects and side effects. Loratadine is an antihistamine that is used to treat allergies, not headaches. It does not have any pain-relieving or anti-inflammatory properties. Caffeine is not an ingredient in acetaminophen, naproxen, or loratadine products.

Correct Answer is D
Explanation
Choice A reason: This is incorrect. Aspirin can be used to relieve headache, but that is not its main function in this context. Aspirin is prescribed to patients who have had a heart attack to reduce the risk of another one.
Choice B reason: This is incorrect. Aspirin can be used to reduce fever, but that is not its main function in this context. Aspirin is prescribed to patients who have had a heart attack to reduce the risk of another one.
Choice C reason: This is incorrect. Aspirin does not act as an antiviral. It has no effect on viral infections. Aspirin is prescribed to patients who have had a heart attack to reduce the risk of another one.
Choice D reason: This is correct. Aspirin prevents further clot formation by inhibiting the activity of platelets, which are blood cells that help form clots. Clots can block the blood flow to the heart and cause a heart attack. Aspirin reduces the chance of this happening by making the blood less sticky.
Correct Answer is C
Explanation
Choice A reason: Serum potassium level of 5.5 mEq/L is above the normal range of 3.55.0 mEq/L, but it is not a concern for the client taking Lasix, which is a medication that increases the urine output and lowers the blood pressure by inhibiting the reabsorption of sodium and water in the kidney. Lasix can also cause the loss of potassium in the urine, which can lead to hypokalemia, a condition that causes muscle weakness, cramps, arrhythmias, or cardiac arrest. The nurse should monitor the serum potassium level and administer potassium supplements or potassium sparing diuretics as prescribed to prevent hypokalemia.
Choice B reason: Blood pressure of 130/80 mmHg is slightly above the normal range of 120/80 mmHg, but it is not a concern for the client taking Lasix, which is a medication that increases the urine output and lowers the blood pressure by inhibiting the reabsorption of sodium and water in the kidney. Lasix can reduce the fluid volume and the peripheral resistance, which can lower the blood pressure and prevent or treat hypertension, edema, or heart failure. The nurse should monitor the blood pressure regularly and adjust the dose of Lasix as prescribed to maintain a normal blood pressure.
Choice C reason: Serum potassium level of 3.0 mEq/L is below the normal range of 3.55.0 mEq/L, and it is a concern for the client taking Lasix, which is a medication that increases the urine output and lowers the blood pressure by inhibiting the reabsorption of sodium and water in the kidney. Lasix can also cause the loss of potassium in the urine, which can lead to hypokalemia, a condition that causes muscle weakness, cramps, arrhythmias, or cardiac arrest. The nurse should notify the health care provider immediately and prepare to administer interventions such as potassium supplements or potassium sparing diuretics to correct hypokalemia.
Choice D reason: Serum sodium level of 140 mEq/L is within the normal range of 135145 mEq/L, and it is not a concern for the client taking Lasix, which is a medication that increases the urine output and lowers the blood pressure by inhibiting the reabsorption of sodium and water in the kidney. Lasix can cause the loss of sodium in the urine, which can lead to hyponatremia, a condition that causes confusion, seizures, coma, or death. The nurse should monitor the serum sodium level and administer sodium supplements or fluids as prescribed to prevent hyponatremia.
