Penicillin has cross-sensitivity to which of the following drug classes?
Aminoglycosides
Erythromycins
Quinolones
Cephalosporins
The Correct Answer is D
A. Aminoglycosides: Aminoglycosides are a different class of antibiotics. They do not have cross-sensitivity with penicillin. People who are allergic to penicillin can usually take aminoglycosides without a problem.
B. Erythromycins: Erythromycins are macrolide antibiotics. They are not related to penicillin structurally, so there is no cross-sensitivity between penicillin and erythromycins. People allergic to penicillin can generally take erythromycin without issues.
C. Quinolones: Quinolones, also known as fluoroquinolones, are a different class of antibiotics. They do not share a structural similarity with penicillin, so there is usually no cross-sensitivity between penicillin and quinolones. People allergic to penicillin can usually take quinolones without problems.
D. Cephalosporins: Cephalosporins are beta-lactam antibiotics, just like penicillins. They have a similar chemical structure to penicillins, which can lead to cross-sensitivity. Individuals who are allergic to penicillin might also have an allergic reaction to cephalosporins due to this structural resemblance. However, it's important to note that not all cephalosporins are the same, and the risk of cross-reactivity varies among different generations of cephalosporins. Healthcare providers need to assess the specific situation and choose an appropriate antibiotic if there is a known penicillin allergy.

Correct Answer is D
Explanation
A. "The antibiotic I have been taking doesn't work as well as it used to."
This statement shows awareness of decreased effectiveness, which can occur due to drug resistance. Bacteria can become resistant to antibiotics, leading to reduced efficacy of the medication over time.
B. "The bacteria in my body have become resilient."
This statement correctly attributes resistance to the bacteria. Resilience in this context means that bacteria have developed mechanisms to survive the effects of antibiotics, making the treatment less effective.
C. "Over time, an organism that had once been highly sensitive to an antibiotic may become less susceptible, or it may lose drug sensitivity entirely."
This statement accurately describes the concept of drug resistance. Bacteria can lose sensitivity to antibiotics, rendering the drugs ineffective against them.
D. "My body has become resistant to the antibiotic."
This statement is incorrect. It's the bacteria that develop resistance, not the patient's body. Patients don't become resistant to antibiotics; instead, bacteria evolve and adapt, making the drugs less effective against them.
Correct Answer is D
Explanation
A. Reddened tongue and gums: This side effect is not typically associated with ampicillin. However, certain medications or medical conditions can cause changes in oral tissues, leading to redness in the tongue and gums.
B. Digit numbness and tingling: Ampicillin does not commonly cause numbness and tingling in the fingers and toes. These symptoms can be associated with neurological issues or circulatory problems.
C. Bruising and petechiae: These symptoms can indicate bleeding disorders or low platelet count and are not usually caused by ampicillin. It's essential to investigate further if a patient experiences unexplained bruising or petechiae.
D. Skin rash and loose stools: Skin rash is a known side effect of penicillin-type antibiotics, including ampicillin. Loose stools or diarrhea can also occur due to disruption of the gut flora caused by the antibiotic. Patients should be aware of these possibilities and report any severe or persistent symptoms to their healthcare provider.
