A nurse is preparing to administer the initial dose of penicillin G IM to a client. The nurse should monitor for which of the following as an indication of an allergic reaction following the injection?

A. Peanuts:
While peanut allergies can be severe and life-threatening, they are not a contraindication to receiving the influenza vaccine. Influenza vaccines are not made with peanut-derived ingredients and do not pose a risk to individuals with peanut allergies.
B. Milk:
Milk allergies are not a contraindication to receiving the influenza vaccine. Influenza vaccines are typically free of milk-derived ingredients and do not contain significant amounts of milk proteins that would trigger an allergic reaction in individuals with milk allergies.
C. Shellfish:
Shellfish allergies are not a contraindication to receiving the influenza vaccine. Influenza vaccines are not derived from shellfish and do not contain shellfish proteins that could cause an allergic reaction in individuals with shellfish allergies.

D. Eggs:
This is the correct choice. In the past, some influenza vaccines were prepared using egg-based methods, which could pose a risk to individuals with severe egg allergies. However, most modern influenza vaccines, including those approved for administration in the United States, have extremely low egg protein content. The majority of individuals with egg allergies can safely receive the influenza vaccine, but those with a history of severe egg allergy may still need to consult with their healthcare provider before vaccination.

A. Multiple health problems: Older adults often have multiple chronic health conditions, which can increase the risk of interactions between medications or exacerbate the effects of certain drugs.
B. Decreased renal function: As people age, their kidney function tends to decrease, which can affect the clearance of drugs from the body. Drugs that are primarily excreted through the kidneys may accumulate in older adults with reduced renal function.
C. Polypharmacy: Older adults are more likely to be taking multiple medications simultaneously. This increases the risk of drug interactions and adverse effects.
D. Decreased percentage of body fat: With age, there is a decrease in lean body mass and an increase in body fat. Fat-soluble drugs can accumulate in body fat, leading to prolonged drug effects and increased risk of toxicity.
E. Increased rate of absorption: Aging can lead to changes in gastrointestinal function, including reduced gastric motility and decreased blood flow to the gastrointestinal tract. These changes may result in delayed drug absorption rather than an increased rate of absorption.
