Acquired resistance is:

substance that can inhibit the growth of bacteria

ability of an organism to cause disease in humans

the severity of a disease that an organism is able to cause

when a microbe is no longer affected by a drug following treatment with an anti-infective

Answer and Explanation

The Correct Answer is D

A. Substance that can inhibit the growth of bacteria: This describes an antibiotic, not acquired resistance.
B. Ability of an organism to cause disease in humans: This describes pathogenicity, not acquired resistance.
C. The severity of a disease that an organism is able to cause: This describes virulence, not acquired resistance.
D. When a microbe is no longer affected by a drug following treatment with an anti-infective: This is the correct definition of acquired resistance. Over time, microbes can develop mechanisms to evade the effects of antibiotics, rendering them ineffective.

Correct Answer is ["A","D"]

Explanation

A. Insulin: Insulin is produced by the beta cells of the pancreas and lowers blood glucose levels by facilitating the uptake of glucose into cells.
B. Growth hormone: Growth hormone is produced by the pituitary gland, not the pancreas. It can affect blood glucose levels indirectly but is not a pancreatic hormone.
C. Estrogen: Estrogen is produced primarily by the ovaries, not the pancreas. It does not directly regulate blood glucose levels.
D. Glucagon: Glucagon is produced by the alpha cells of the pancreas and raises blood glucose levels by promoting the conversion of glycogen to glucose in the liver.
E. Antidiuretic hormone: Antidiuretic hormone (ADH) is produced by the hypothalamus and released by the pituitary gland. It regulates water balance in the body, not blood glucose levels.

A. Erythromycin (E-mycin) B. piperacillin-tazobactar (Zosyn) C. ampicillin sulbactam (Unasyn) D. cefazolin (Kefzol)

Correct Answer is A

Explanation

A. Erythromycin (E-mycin): Erythromycin is a macrolide antibiotic, which has a different chemical structure from penicillins, making it safe for patients with penicillin allergies.
B. Piperacillin-tazobactam (Zosyn): Piperacillin-tazobactam is a penicillin derivative and should be avoided in patients with penicillin allergies due to the risk of cross-reactivity.
C. Ampicillin sulbactam (Unasyn): Ampicillin is a penicillin antibiotic, and therefore, should not be used in patients with penicillin allergies.
D. Cefazolin (Kefzol): Cefazolin is a cephalosporin antibiotic. There is a potential for cross-reactivity in patients with penicillin allergies, especially if the allergy is severe. It may be used with caution or avoided depending on the patient's allergy history.
