A nurse is planning to administer an IM injection into a client's deltoid muscle. Which action should the nurse take?

Inject a volume of less than 2 mL.

Inject the medication at a 90 degree angle.

Inject the medication 12.7 cm (5 in) below the client's acromion process.

Use a 21-gauge needle for the injection.

Answer and Explanation

The Correct Answer is B

A) Inject a volume of less than 2 mL: While it is generally recommended to inject a volume of less than 2 mL into the deltoid muscle to avoid discomfort and ensure proper absorption, this is not the primary action to focus on when planning the injection.

B) Inject the medication at a 90 degree angle: This is the correct action. Administering an intramuscular (IM) injection at a 90-degree angle ensures that the medication is delivered deep into the muscle tissue, which is necessary for proper absorption and effectiveness.

C) Inject the medication 12.7 cm (5 in) below the client’s acromion process: The correct injection site for the deltoid muscle is typically 2-3 finger widths (approximately 2.5-5 cm) below the acromion process, not 12.7 cm. Injecting too far below the acromion process could result in an incorrect injection site.

D) Use a 21-gauge needle for the injection: While a 21-gauge needle can be used for IM injections, the gauge of the needle is not the primary focus in this context. The angle of injection is more critical to ensure proper delivery of the medication.

Correct Answer is C

Explanation

A) Distribution, Excretion, Absorption, Metabolism: This order is incorrect because absorption should occur before distribution. The medication must first be absorbed into the bloodstream before it can be distributed throughout the body. Excretion and metabolism follow after distribution, not before.

B) Absorption, Excretion, Metabolism, Distribution: This sequence is incorrect because distribution occurs after absorption and before metabolism. Excretion is the final step and occurs after metabolism.

C) Absorption, Distribution, Metabolism, Excretion: This is the correct order. After oral administration, the medication is first absorbed into the bloodstream from the gastrointestinal tract. It is then distributed throughout the body. Following distribution, the medication undergoes metabolism (primarily in the liver) to be converted into more water-soluble forms for elimination. Finally, the medication is excreted from the body, typically through the kidneys

D) Absorption, Metabolism, Distribution, Excretion: This order is incorrect because metabolism occurs after distribution, not before. After absorption, the drug must be distributed to various tissues before it is metabolized. Excretion is the final step following metabolism.

A. Affinity B. Efficacy C. Biotransformation D. Pharmacokinetics E. Pharmacodynamics

Correct Answer is ["D","E"]

Explanation

A) Affinity: Affinity refers to the strength of the interaction between a drug and its receptor. It does not describe the body's overall handling of the drug or the drug's effects on the body.

B) Efficacy: Efficacy describes the ability of a drug to produce a desired therapeutic effect. It pertains to the drug’s effectiveness once it interacts with its target but does not encompass the body's handling of the drug.

C) Biotransformation: Biotransformation is the process of drug metabolism, specifically how the body chemically alters a drug. While it is a part of pharmacokinetics, it does not cover the entire concept.

D) Pharmacokinetics: Pharmacokinetics is the term used to describe what the body does with the drug, including absorption, distribution, metabolism, and excretion. It encompasses the processes that determine the drug's concentration in the body over time.

E) Pharmacodynamics: Pharmacodynamics refers to what the drug does to the body, including the relationship between drug concentration and effect. It encompasses the mechanisms of action, including receptor interactions and therapeutic effects.
