When describing the differences affecting the pharmacokinetics of drugs administered to children, which would the nurse include?

Absorption of drugs administered by subcutaneous injection is increased.

Absorption of intramuscularly administered drugs is fairly constant.

Topical drugs are absorbed more quickly in young children than adults.

Oral drugs are absorbed more quickly in children than adults.

Answer and Explanation

The Correct Answer is B

A. Absorption of drugs administered by subcutaneous injection is increaseD. Subcutaneous absorption can vary based on factors such as blood flow and tissue characteristics, but it is generally slower and more variable compared to intramuscular absorption.

B. Absorption of intramuscularly administered drugs is fairly constant: Intramuscular absorption tends to be more consistent compared to subcutaneous absorption. However, absorption rates can still be affected by factors such as muscle mass and blood flow.

C. Topical drugs are absorbed more quickly in young children than adults: Topical drug absorption can be influenced by factors such as skin thickness and permeability, but absorption rates may not necessarily be faster in young children compared to adults.

D. Oral drugs are absorbed more quickly in children than adults: This statement is generally incorrect. While gastrointestinal transit time may be faster in children, other factors such as

gastric pH and enzymatic activity can affect oral drug absorption, and absorption rates may not always be faster in children compared to adults.

Correct Answer is C

Explanation

A. A Jewish male. While certain genetic factors may predispose individuals to hypertension, ethnicity or religious affiliation alone is not a direct risk factor for hypertension. Screening for hypertension should be based on individual risk factors and not solely on ethnicity or religion.

B. A white male. While hypertension can affect individuals of any race or ethnicity, it is less prevalent among white populations compared to African-American populations. However, hypertension can still occur in white males, especially if they have other risk factors such as obesity, family history, or unhealthy lifestyle habits.

C. An African-American male. African-American individuals, particularly males, have a higher prevalence of hypertension compared to other racial and ethnic groups. Genetic predisposition, as well as socio-economic factors and healthcare disparities, contribute to this increased risk.

Therefore, it is important to screen African-American males for hypertension, starting from adolescence, to ensure early detection and management.

D. An Asian female. While hypertension can affect individuals of Asian descent, the prevalence is generally lower compared to other racial and ethnic groups such as African-Americans. However, certain subgroups within the Asian population, such as South Asians, may have higher rates of hypertension due to genetic and lifestyle factors. Screening for hypertension should be based on individual risk factors rather than broad racial or ethnic categories.

A. Genitourinary B. Hematologic C. Endocrine D. Neurologic

Correct Answer is C

Explanation

A. Genitourinary: This system pertains to the urinary tract and reproductive organs and is not directly related to increased appetite or thirst.

B. HematologiC. This system involves the blood and blood-forming organs such as the bone marrow, spleen, and lymph nodes. Increased appetite or thirst is not typically associated with hematologic issues.

C. EndocrinE. The endocrine system includes glands that secrete hormones, such as the pancreas, which regulates blood sugar levels. Increased appetite or thirst can be indicative of endocrine disorders like diabetes mellitus, where there may be abnormalities in insulin production or response.

D. NeurologiC. While the nervous system can indirectly influence appetite and thirst regulation, directly asking about increased appetite or thirst primarily pertains to the endocrine system's hormonal regulation
