Where should a patient administer subcutaneous insulin for the fastest absorption?

A.

Upper arm

B.

Thigh

C.

Buttocks

D.

Abdomen

Answer and Explanation

The Correct Answer is D

A. Upper arm: The upper arm is an acceptable site for subcutaneous injections, but absorption is slower compared with the abdomen due to less vascularized subcutaneous tissue.

B. Thigh: The thigh is commonly used for subcutaneous injections, but absorption is slower than the abdomen. This site is often chosen for convenience rather than rapid onset.

C. Buttocks: The buttocks have thicker subcutaneous tissue and slower blood flow, resulting in slower absorption of insulin compared with other sites.

D. Abdomen: The abdomen provides the fastest absorption for subcutaneous insulin because it has rich vascularization and a consistent layer of subcutaneous fat, making it ideal for rapid onset of action.

Explanation

  • Available Concentration: 50 mg/mL

Ordered Dose: 125 mg

  • Calculate the volume to administer

Volume to administer = Ordered Dose ÷ Concentration

Volume to administer = 125 ÷ 50

Volume to administer = 2.5 mL

Correct Answer is B

Explanation

Calculation:

  • Convert the prescribed dose to the same unit as the available tablets

Prescribed Dose: 0.75 g

= 750 mg

Available Tablet Strength: 250 mg per tablet

  • Calculate the number of tablets to administer

Number of Tablets = Prescribed Dose ÷ Tablet Strength

Number of Tablets = 750 ÷ 250

Number of Tablets = 3 tablets
