A nurse is administering penicillin to a client who has streptococcal pharyngitis. The nurse should monitor for which adverse effect of penicillin therapy?

Hypokalemia

Hyperglycemia

Anaphylaxis

Constipation.

Elevated platelet count.

Answer and Explanation

The Correct Answer is C

Anaphylaxis is a severe allergic reaction that can be life-threatening and requires immediate medical attention. Penicillin is one of the most common causes of anaphylaxis. Symptoms of anaphylaxis include difficulty breathing, swelling of the face, throat, or tongue, hives, itching, low blood pressure, and shock.

Choice A is wrong because hypokalemia (low potassium levels in the blood) is not a common or serious side effect of penicillin therapy. Hypokalemia can cause muscle weakness, cramps, irregular heartbeat, and fatigue.

Choice B is wrong because hyperglycemia (high blood sugar levels) is not a common or serious side effect of penicillin therapy. Hyperglycemia can cause thirst, frequent urination, blurred vision, and headaches.

Choice D is wrong because constipation is not a common or serious side effect of penicillin therapy. Constipation can cause abdominal pain, bloating, and difficulty passing stools.

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

Explanation

A microbe acquires antibiotic resistance by transferring DNA coding to other bacteria or by spontaneous mutation in the microbial genome.

These genetic changes allow the microbe to survive the effects of the antibiotic and pass on the resistance to its offspring.

ChoiceAis wrong because the host does not develop medication resistance, but the microbe does.

ChoiceBis wrong because the minimum bactericidal concentration (MBC) is the lowest concentration of an antibiotic needed to kill 99.9% of bacteria, not a mechanism of resistance.

ChoiceCis wrong because incorrect dosing does not cause ribosome mutations, but may promote the emergence of drug-resistant microbes by exposing them to suboptimal levels of the antibiotic.

A. First-generation B. Second-generation C. Third-generation D. Fourth-generation.

Correct Answer is C

Explanation

Ceftriaxone belongs to the third-generation of cephalosporins.Third-generation cephalosporins have greater activity than the second-generation cephalosporins against certain gram-negative bacteria, such as Streptococcus pneumoniae.They are also more resistant to beta-lactamases, enzymes that can inactivate some cephalosporins.

Choice A is wrong because first-generation cephalosporins have less activity against gram-negative bacteria and are more susceptible to beta-lactamases.

Choice B is wrong because second-generation cephalosporins have less activity against Streptococcus pneumoniae than third-generation cephalosporins, and are also less resistant to beta-lactamases.

Choice D is wrong because fourth-generation cephalosporins have a broader spectrum of activity against gram-negative bacteria, including some that are resistant to third-generation cephalosporins, but they are not more effective against Streptococcus pneumoniae.
