A nurse is preparing to administer acetaminophen 10 mg/kg PO every 6 hr to a toddler who weighs 26.4 lb. Available is acetaminophen 80 mg/0.8 mL liquid. How many mL should the nurse administer with each dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

B. Hemoglobin levels should be monitored regularly to assess the effectiveness of epoetin alfa therapy. Epoetin alfa stimulates the production of red blood cells, which should result in an increase in hemoglobin levels over time in clients with anemia. Monitoring hemoglobin levels helps determine if the medication is achieving the desired therapeutic effect.

A. Thrombin time measures the time it takes for a clot to form in a blood sample after thrombin is added. It is primarily used to assess abnormalities in the conversion of fibrinogen to fibrin during the clotting process. Thrombin time is not typically monitored to assess the effectiveness of epoetin alfa.
C. AST is an enzyme found primarily in the liver and heart. Elevated AST levels may indicate liver or heart damage but are not specifically related to the effectiveness of epoetin alfa therapy. AST is not routinely monitored to assess the effectiveness of epoetin alfa.
D. Troponin is a cardiac biomarker used to diagnose myocardial infarction (heart attack). Elevated troponin levels indicate damage to the heart muscle. Troponin levels are not directly related to the effectiveness of epoetin alfa therapy and are not routinely monitored for this purpose.

D. Atenolol is a beta-blocker used to treat hypertension and lower heart rate. Given the client's low heart rate of 54 beats per minute (bradycardia), there is a potential concern about further lowering the heart rate with atenolol. Therefore, the nurse should consider withholding atenolol and consulting with the healthcare provider regarding the low heart rate before administering the medication.
A. Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor used to treat hypertension. With a blood pressure of 140/80 mm Hg, it is within the normal range for a client with chronic hypertension.
B. Hydrochlorothiazide is a diuretic commonly used to treat hypertension. With a blood pressure of 140/80 mm Hg, it is within the normal range for a client with chronic hypertension. Therefore, there is no immediate need to withhold hydrochlorothiazide based on the current blood pressure reading.
C. Aspirin is commonly used for cardiovascular protection in clients with hypertension. It is not typically withheld based on blood pressure readings alone unless there are other contraindications or concerns.
