While instructing a patient about antibiotic therapy, the nurse explains to the patient that bacterial resistance to antibiotics can occur when:
Antibiotics are prescribed according to culture and sensitivity reports.
Patients stop taking an antibiotic after they feel better.
Antibiotics are taken with ascorbic acid (vitamin C).
Antibiotics are taken with water or juice.
The Correct Answer is B
A. Antibiotics are prescribed according to culture and sensitivity reports:
When antibiotics are prescribed based on specific tests like cultures and sensitivity reports, it ensures that the right antibiotic is chosen for the specific bacteria causing the infection. This practice helps in targeting the infection more effectively, reducing the risk of antibiotic resistance.
B. Patients stop taking an antibiotic after they feel better:
This scenario is problematic. When patients start feeling better, they might assume the infection is completely gone and stop taking antibiotics before the prescribed course is finished. This premature discontinuation can leave some bacteria alive, which may develop resistance to the antibiotic used. This practice is a significant contributor to antibiotic resistance.
C. Antibiotics are taken with ascorbic acid (vitamin C):
Ascorbic acid (vitamin C) doesn't have a significant impact on antibiotic resistance. It is not a factor contributing to antibiotic resistance.
D. Antibiotics are taken with water or juice:
Whether antibiotics are taken with water or juice doesn’t directly influence antibiotic resistance. Proper hydration is essential to support the body's overall health, but it doesn't impact the development of antibiotic resistance.

Correct Answer is C
Explanation
A. "Cephalosporins are assigned to generations based on their relative costs to administer."
This statement is incorrect. The classification of cephalosporins into generations is based on their antimicrobial spectrum and activity against specific bacteria, not their cost.
B. "Later generations of cephalosporins have lower resistance to destruction by beta-lactamases."
This statement is not accurate. In fact, later generations of cephalosporins have increased resistance to destruction by beta-lactamases, which are enzymes produced by bacteria that can break down certain antibiotics.
C. "Cephalosporins have increased activity against gram-negative bacteria with each new generation."
This statement is correct. Cephalosporins are grouped into generations (first to fifth) based on their antibacterial spectrum. As the generations progress, there is an increase in activity against gram-negative bacteria, among other improvements in their spectrum.
D. "First-generation cephalosporins have better penetration of the cerebrospinal fluid."
This statement is generally true. First-generation cephalosporins have better penetration into the cerebrospinal fluid, making them useful for treating certain central nervous system infections.
Correct Answer is C
Explanation
A. Dermatitis and headaches: Prednisone use can sometimes cause skin issues, but dermatitis is not a common side effect. Headaches can also occur, but they are not specific to long-term prednisone therapy.
B. Heart failure and headaches: Prednisone does not directly cause heart failure. Headaches can occur but are not specific indicators of prednisone side effects.
C. Hyperglycemia and osteoporosis: Prednisone can lead to elevated blood glucose levels (hyperglycemia) and increased bone loss (osteoporosis) when used long-term. Regular monitoring is essential to manage these potential side effects.
D. Weight loss and hypoglycemia: Prednisone can cause weight gain rather than weight loss. Hypoglycemia (low blood sugar) is not a common side effect of prednisone; it typically causes hyperglycemia (high blood sugar) instead.
