The nurse is to administer 3 mL of medication intramuscularly to an adult patient. Which is the appropriate site for the injection?

Dorsal gluteal

Deltoid

Vastus lateralis

Lateral piriformis

Answer and Explanation

The Correct Answer is C

Choice A rationale:

The dorsal gluteal site (also known as the dorsogluteal site) was previously a common injection site, but it's now not recommended due to several significant risks:

Proximity to the sciatic nerve: The sciatic nerve is the largest nerve in the body, and it runs close to the dorsal gluteal site. Accidental injection into or near the nerve can cause severe pain, nerve damage, and potential paralysis.

Difficulty in locating landmarks: The landmarks for the dorsal gluteal site can be difficult to locate accurately, especially in obese patients or those with decreased muscle mass. This increases the risk of injecting into the wrong area.

Risk of injury to blood vessels: The dorsal gluteal site also has a higher risk of injury to blood vessels, as several large vessels run through the area.

Choice B rationale:

The deltoid muscle is located in the upper arm and is a common site for intramuscular injections, but it has limitations for larger volumes:

Small muscle size: The deltoid muscle is relatively small compared to other IM injection sites. It's generally recommended for smaller volumes of medication (up to 1 mL in adults).

Subcutaneous tissue: The deltoid muscle often has a layer of subcutaneous tissue (fat) that can hinder absorption of medication.

Choice C rationale:

The vastus lateralis muscle is the preferred site for intramuscular injections in adults for several reasons:

Large muscle size: It's a large, thick muscle that can accommodate larger volumes of medication (up to 5 mL in adults). Easy to locate landmarks: The landmarks for the vastus lateralis are easy to identify, even in obese patients.

Few major nerves or blood vessels: It has fewer major nerves or blood vessels in the area, reducing the risk of injury. Pain tolerance: It's generally considered to be a less painful injection site than the deltoid or dorsogluteal sites.

Choice D rationale:

The lateral piriformis muscle is not a recognized or recommended site for intramuscular injections. It's a deep muscle located in the buttocks, and injecting into it would be difficult and potentially dangerous due to its proximity to the sciatic nerve and other important structures.

Correct Answer is A

Explanation

Choice A rationale:

Ineffective breathing pattern related to incisional pain and anesthesia is the priority nursing diagnosis for a patient with shallow respirations following abdominal surgery because it addresses the most immediate and life-threatening concern: impaired gas exchange.

A. 10 years B. 1 year C. 5 years D. 2 years

Correct Answer is A

Explanation

The correct answer is Choice A.

Choice A rationale:

Tetanus is an acute infectious disease caused by spores of the bacterium Clostridium tetani.The spores are found everywhere in the environment, particularly in soil, ash, intestinal tracts/feces of animals and humans, and on the surfaces of skin and rusty tools like nails, needles, barbed wire, etc.Anyone can get tetanus, but the disease is particularly common and serious in newborn babies and pregnant women who have not been sufficiently immunized with tetanus-toxoid-containing vaccines.

To ensure that there is adequate antitoxin to neutralize tetanus toxin in the case of a tetanus-prone injury, a booster dose is advised if it has been longer than 10 years since the last tetanus vaccine dose.This is because a single dose of tetanus toxoid produces a rapid anamnestic response. Therefore, if a patient with a puncture wound has not received a tetanus toxoid vaccination in the last 10 years, they would require an additional injection before being discharged from the emergency department.

Choice B rationale:

While it might seem prudent to administer a tetanus toxoid vaccination every year, this is not necessary according to current medical guidelines.Over-vaccination could potentially lead to an increased risk of adverse reactions without providing additional benefits. Therefore, a tetanus toxoid vaccination is not required every year.

Choice C rationale:

A 5-year interval for tetanus toxoid vaccination is not the standard recommendation for general population.However, in some specific cases, such as when indicated for wound management, a tetanus toxoid–containing vaccine might be administered if ≥5 years have elapsed since the previous receipt of any tetanus toxoid–containing vaccine.

Choice D rationale:

A 2-year interval for tetanus toxoid vaccination is not the standard recommendation.The tetanus toxoid vaccination provides protection for a much longer period, and therefore, it is not necessary to administer the vaccine every 2 years.
