3. Dabigatran decreases the risk of stroke associated with decrease gastric side effects such as dyspepsia and gastritis. Proton pump
atrial fibrillation. inhibitors and histamine 2 recepter blockers may also decrease gastric side
effects.

A client has a prescription for nitroglycerin gr 1/400 SL 0.5
prn for angina pain. How many tablets should the nurse
give the client? Use numbers and decimals only. (Rationale:
Nitroglycerin tablets, USP (0.0025 gr ÷ 1) × (0.3 mg ÷ 0.005 gr) × (1 tab ÷ 0.3 mg) = (0.00075 ÷ 0.0015) = 0.5 tab

drug would be ineffective against the bacteria while too high a level increases the
1. BUN and creatinine. potential for severe side effects or toxicity from this antibiotic.
2. Liver function studies. 1. Incorrect: Because aminoglycosides such as gentamicin can lead to
nephrotoxicity, checking BUN and creatinine levels periodically is important.
3. Hemoglobin and hematocrit. However, it would not be necessary to check those values every three days.
4. Peak and trough levels. 2. Incorrect: Aminoglycosides like gentamicin rarely affect the liver; therefore, liver
function studies would not be needed frequently.
3. Incorrect: Hemoglobin and hematocrit levels are rarely impacted by
aminoglycosides such as gentamicin. Although an initial level may be obtained
prior to treatment, additional levels are not necessary.)

5. Watermelon
2. Incorrect: The level of vitamin K in a cup of raw carrots is 16.9 mcg. Carrots will
not reduce the action of warfarin, due to the low level of vitamin K in corn.
