Question 1

The patient has been prescribed an oral dosage of cephalexin (Keflex) at 325 mg. The medication available is in a concentration of 250 mg per 2 mL. To determine the volume (in mL) the nurse should administer, we perform a dimensional analysis. The calculation yields a required dosage of 2.6 mL.

Dimensional Analysis: [ \frac{2 \, \text{mL}}{325 \, \text{mg}} = \frac{250 \, \text{mg}}{250} ] Calculated Volume: 2.6 mL

Question 2

The patient has been ordered to take amoxicillin (Amoxil) at a dosage of 2.4 g orally. The available amoxicillin comes in a concentration of 600 mg per 10 mL. Following a dimensional analysis, the nurse should administer 40 mL.

Dimensional Analysis: [ \frac{10 \, \text{mL}}{1000 \, \text{mg}} = \frac{2.4 \, \text{g}}{24000} ] Calculated Volume: 40 mL

Question 3

For the patient requiring diphenhydramine HCl (Benadryl) at a dose of 37.5 mg orally, the medication available is 12.5 mg per 10 mL. The nurse will need to administer 30 mL based on the dimensional analysis.

Dimensional Analysis: [ \frac{10 \, \text{mL}}{37.5 \, \text{mg}} = \frac{12.5 \, \text{mg}}{12.5} ] Calculated Volume: 30 mL

Question 4

The order for potassium chloride (K-Lor) is 60 mEq orally. The available concentration is 40 mEq per 10 mL. The calculated volume to administer is 15 mL.

Dimensional Analysis: [ \frac{10 \, \text{mL}}{60 \, \text{mEq}} = \frac{40 \, \text{mEq}}{40} ] Calculated Volume: 15 mL

Question 5

The patient requires gabapentin (Neurontin) at 275 mg orally. The available dosage is 250 mg per 10 mL. The nurse should administer 11 mL.

Dimensional Analysis: [ \frac{10 \, \text{mL}}{275 \, \text{mg}} = \frac{250 \, \text{mg}}{250} ] Calculated Volume: 11 mL

Question 6

For a morphine sulfate (Duramorph) order of 60 mg orally, with an available concentration of 20 mg per 10 mL, the nurse should administer 6 tsp.

Dimensional Analysis: [ \frac{1 \, \text{tsp}}{10 \, \text{mL}} = \frac{60 \, \text{mg}}{600} ] Calculated Volume: 6 tsp

Question 7

The order for tolbutemide (Orinase) is 0.5 g orally, with the available formulation being 250 mg per scored tablet. The nurse will administer 2 tablets.

Dimensional Analysis: [ \frac{1 \, \text{tab}}{1000 \, \text{mg}} = \frac{0.5 \, \text{g}}{500} ] Calculated Volume: 2 tabs

Question 8

For potassium chloride (K Dur), the patient requires 50 mEq orally. The available dosage is 20 mEq per scored tablet, thus the nurse should administer 2.5 tablets.

Dimensional Analysis: [ \frac{1 \, \text{tab}}{50 \, \text{mEq}} = \frac{20 \, \text{mEq}}{20} ] Calculated Volume: 2.5 tabs

Question 9

For a metformin (Glucophage) order of 0.5 g orally, with the medication available as 1000 mg per scored tablet, the calculated administration is 0.5 tablets.

Dimensional Analysis: [ \frac{1 \, \text{tab}}{1000 \, \text{mg}} = \frac{0.5 \, \text{g}}{500} ] Calculated Volume: 0.5 tab

Question 10

The order for atorvastatin (Lipitor) is 50 mg orally, and the available medication is 50 mg per tablet. Therefore, the nurse will administer 1 tablet.

Dimensional Analysis: [ \frac{1 \, \text{tab}}{50 \, \text{mg}} = \frac{50 \, \text{mg}}{50} ] Calculated Volume: 1 tab

Question 11

The patient has been prescribed digoxin (Lanoxin) at 625 mcg orally. The available dosage is 0.25 mg per scored tablet, resulting in an administration of 2.5 tablets.

Dimensional Analysis: [ \frac{1 \, \text{tab}}{1 \, \text{mg}} = \frac{625 \, \text{mcg}}{625} ] Calculated Volume: 2.5 tabs

Question 12

The order for hydrochlorothiazide (HydroDIURIL) is 100 mg orally, with the available formulation being 50 mg per scored tablet. The nurse should administer 2 tablets.

Dimensional Analysis: [ \frac{1 \, \text{tab}}{100 \, \text{mg}} = \frac{50 \, \text{mg}}{50} ] Calculated Volume: 2 tabs

Question 13

For the ordered cyclosporine (Neoral) at 4 mg/kg/day, and given the patient’s weight of 162 lb, the nurse will administer 295 mg daily.

Dimensional Analysis: [ 4 \, \text{mg} \times \frac{162 \, \text{lb}}{1 \, \text{kg}} \times \frac{1 \, \text{kg}}{2.2 \, \text{lb}} = 294.5 \text{ (rounded to 295 mg)} ]

Question 14

The patient has been ordered sulfasalazine (Axulfidine) at 0.25 g orally, with the available medication being 250 mg per scored tablet. The nurse will administer 1 tablet.

Dimensional Analysis: [ \frac{1 \, \text{tab}}{1000 \, \text{mg}} = \frac{0.25 \, \text{g}}{250} ] Calculated Volume: 1 tab

Question 15

The order for atropine (AtroPen) is 450 mcg subcutaneously. The available formulation is 0.5 mg per 0.7 mL. The calculated volume for administration is 0.6 mL.

Dimensional Analysis: [ \frac{0.7 \, \text{mL}}{1 \, \text{mg}} = \frac{450 \, \text{mcg}}{315} ] Calculated Volume: 0.6 mL

Question 16

For enoxaparin (Lovenox) at 1 mg/kg subcutaneously, the patient weighs 180 lb. The nurse will administer 0.8 mL.

Dimensional Analysis: [ 1 \, \text{mL} \times \frac{1 \, \text{mg}}{1 \, \text{kg}} \times \frac{180 \, \text{lb}}{2.2 \, \text{lb}} = 0.8 \text{ mL} ]

Question 17

The patient has an order for digoxin (Lanoxin) 0.75 mg IVP. The medication available is 500 mcg/mL. The calculated volume for administration is 1.5 mL.

Dimensional Analysis: [ \frac{1 \, \text{mL}}{1000 \, \text{mcg}} = \frac{0.75 \, \text{mg}}{750} ] Calculated Volume: 1.5 mL

Question 18

The order for cyanocobalamin (Vitamin B12) is 70 mcg subcutaneously, with the available dosage at 0.1 mg/mL. The nurse will administer 0.7 mL.
