Which of the following types of patients are more vulnerable to drug toxicity?

Immunocompromised patients

Immunocompetent patients

Infants and elderly patients

Patients who have allergic reactions

Answer and Explanation

The Correct Answer is A

A. Immunocompromised patients:

Immunocompromised patients, whose immune systems are weakened or impaired, are indeed more vulnerable to drug toxicity. This vulnerability can be due to factors such as decreased ability to metabolize and eliminate drugs, increased susceptibility to infections and opportunistic pathogens, and impaired organ function, particularly in the liver and kidneys, which are involved in drug metabolism and excretion.

B. Immunocompetent patients:

Immunocompetent patients have normal immune function and are generally less vulnerable to drug toxicity compared to immunocompromised individuals. However, susceptibility to drug toxicity can still vary depending on factors such as age, underlying health conditions, renal and hepatic function, and concurrent use of other medications.

C. Infants and elderly patients:

Infants and elderly patients are more vulnerable to drug toxicity due to factors such as immature or declining organ function, altered drug metabolism and elimination, and differences in body composition. In infants, organ systems are still developing, while in elderly patients, age-related changes can affect drug pharmacokinetics and increase the risk of adverse reactions.

D. Patients who have allergic reactions:

Patients who have allergic reactions may experience adverse drug reactions if they are exposed to the offending medication again. However, this does not necessarily make them more vulnerable to drug toxicity in general. Allergic reactions are specific immune responses and differ from drug toxicity, which can occur due to various mechanisms unrelated to allergies.

Correct Answer is B

Explanation

A. Bacteriostatics are narrow spectrum drugs, and bactericidal drugs are broad spectrum:

This statement is incorrect. The spectrum of activity (narrow vs. broad) of an antibiotic refers to the range of bacterial species that it can target, not whether it is bacteriostatic or bactericidal.

B. Bacteriostatic drugs inhibit bacterial growth, and bactericidal drugs actually kill bacteria:

This statement is correct. Bacteriostatic drugs work by inhibiting the growth and reproduction of bacteria without directly killing them, whereas bactericidal drugs directly kill bacteria.

C. Bacteriostatics work by inhibiting protein synthesis, and bactericidal drugs work by inhibiting nucleic acid synthesis:

This statement is incorrect. Both bacteriostatic and bactericidal drugs can target various bacterial cellular processes, including protein synthesis, nucleic acid synthesis, cell wall synthesis, and others. The mechanism of action is not a definitive factor in distinguishing between bacteriostatic and bactericidal drugs.

D. Bacteriostatic drugs actually kill bacteria, and bactericidal drugs inhibit bacterial growth:

This statement is incorrect. It contradicts the established definitions of bacteriostatic and bactericidal drugs. Bacteriostatic drugs inhibit bacterial growth without killing the bacteria, while bactericidal drugs directly kill bacteria.

Correct Answer is ["0.6"]

Explanation

To calculate the volume of diazepam solution needed, we can use the formula:

Volume (mL) = Total dose (mg) / Concentration (mg/mL)

Given:

Total dose = 3 mg

Concentration = 5 mg/mL

Plugging the values into the formula:

Volume (mL) = 3 mg / 5 mg/mL

Volume (mL) = 0.6 mL

The nurse should administer: 0.6 mL
