The patient is being discharged on furosemide (Lasix). The nurse evaluates the patient as understanding medication teaching if the patient states that which of the following laboratory tests will be monitored as ordered?
I will have my potassium level checked.
I will have my calcium level checked.
I will have my prothrombin time checked.
I will have my urine sodium checked.
The Correct Answer is A
Choice A reason: Furosemide is a loop diuretic that can cause hypokalemia, so monitoring potassium levels is important.
Choice B reason: While calcium levels can be affected by furosemide, it is not typically the primary concern.
Choice C reason: Prothrombin time is not usually affected by furosemide and is not routinely monitored unless the patient is on anticoagulant therapy.
Choice D reason: Urine sodium could be checked, but it is the serum potassium that is most commonly monitored due to the risk of hypokalemia with furosemide use.

Correct Answer is D
Explanation
Choice A reason: While aspirin does have anti-inflammatory properties, the primary reason for prescribing it post-myocardial infarction is not to reduce inflammation.
Choice B reason: Aspirin can provide pain relief, but this is not the main purpose of its prescription following a myocardial infarction.
Choice C reason: Fever prevention is not a relevant effect in the context of aspirin use for coronary artery disease.
Choice D reason: Aspirin is prescribed to prevent blood clotting. It inhibits platelet aggregation, which is crucial in reducing the risk of further heart attacks by preventing clots that can occlude coronary arteries.
Correct Answer is C
Explanation
Choice A reason: Determining a target heart rate is not the primary purpose of an exercise stress electrocardiogram; it is more about observing the heart's function under stress³.
Choice B reason: Identifying the need for more exercise is not the direct outcome of this test; it is used to assess cardiovascular response to stress³.
Choice C reason: The test is designed to show how the heart performs during exercise, which can help diagnose conditions like coronary artery disease³.
Choice D reason: Predicting a heart attack is not the purpose of an exercise stress electrocardiogram; rather, it helps to identify heart conditions that may lead to complications if left untreated³.
