The nurse notes a reddened area on the right heel that does not turn lighter in color when pressed with a finger.


Which term will the nurse use to describe this area?

Choice A rationale:

Incorrect because swallowing the tablet with water would lead to slower absorption and a delayed onset of action. Nitroglycerin is rapidly absorbed through the oral mucosa, and swallowing it would route it through the digestive system, where it would be absorbed more slowly and less effectively.

Swallowing the tablet could also increase the risk of side effects, such as headache and flushing, due to the larger amount of the drug that would be absorbed systemically.

Choice B rationale:

Incorrect because crushing the tablet and dissolving it in water would also delay its absorption. This method would require the tablet to dissolve in the water before it could be absorbed through the oral mucosa, which would slow down the onset of action.

Crushing the tablet could also damage the medication and make it less effective.

Choice C rationale:

Incorrect because placing the tablet in the patient's mouth next to the cheek would not allow for optimal absorption. The oral mucosa under the tongue is more permeable than the cheek, so placing the tablet under the tongue allows for faster and more efficient absorption.

Placing the tablet in the cheek could also increase the risk of the patient accidentally swallowing it.

Choice D rationale:

Correct because placing the tablet under the patient's tongue allows for rapid absorption and a quick onset of action. The sublingual route is the preferred method of administration for nitroglycerin because it allows the medication to bypass the digestive system and be absorbed directly into the bloodstream.

This method also allows for the patient to easily remove the tablet if they experience any side effects.

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.
