A nurse is preparing to administer tobramycin 3 mg/kg/day IM in three divided doses to a client who weighs 85 kg. The amount available is Tobramycin 40 mg/mL. How many mL should the nurse administer per dose?
(Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Choice A reason: This is incorrect because 30 minutes is too long to wait for reassessing a client with chest pain. Nitroglycerin has a rapid onset of action and should relieve chest pain within 5 minutes. If not, the client may need another dose or emergency care.

Choice B reason: This is correct because 5 minutes is the appropriate time to reassess a client after administering nitroglycerin sublingual. The nurse should check the client's blood pressure, heart rate, and pain level. If the pain persists, the nurse should follow the protocol for giving another dose or calling for help.

Choice C reason: This is incorrect because 1 hour is too long to wait for reassessing a client with chest pain. Nitroglycerin has a short duration of action and may need to be repeated every 5 minutes for up to 3 doses. Waiting for an hour may put the client at risk of worsening cardiac ischemia or infarction.

Choice D reason: This is incorrect because 15 minutes is too long to wait for reassessing a client with chest pain. Nitroglycerin should have an effect within 5 minutes. If the pain is not relieved by then, the client may need another dose or emergency care.

Choice A reason: This is correct because high lipid levels, such as cholesterol and triglycerides, are a risk factor for cardiovascular disease. HMG-CoA reductase inhibitors, also known as statins, lower the production of cholesterol in the liver and reduce the risk of heart attack and stroke.

Choice B reason: This is incorrect because blood glucose of 60 is not related to the need for an HMG-CoA reductase inhibitor. Blood glucose of 60 is below the normal range and may indicate hypoglycemia, which is a low blood sugar level. Hypoglycemia can cause symptoms such as dizziness, confusion, sweating, and hunger.

Choice C reason: This is incorrect because platelets over 150,000 are not related to the need for an HMG-CoA reductase inhibitor. Platelets are blood cells that help with clotting and prevent bleeding. The normal range of platelets is 150,000 to 450,000 per microliter of blood. Platelets over 150,000 are within the normal range and do not indicate a problem.

Choice D reason: This is incorrect because low INR is not related to the need for an HMG-CoA reductase inhibitor. INR stands for international normalized ratio and is a measure of how long it takes the blood to clot. The normal range of INR is 0.8 to 1.2. Low INR means the blood clots faster than normal and may indicate a risk of thrombosis, which is a blood clot in a vein or artery.
