Nokea
Which of the following organism is notorious for developing antimicrobial resistance rapidly?:
- A. Streptococcus pyogenes
- B. Meningococcus
- C. Treponema pallidum
- D. Escherichia coli
Correct Answer: D
Rationale: The correct answer is D: Escherichia coli. E. coli is notorious for developing antimicrobial resistance rapidly due to its ability to acquire resistance genes through plasmid exchange and mutation. This bacterium is commonly found in the gut of humans and animals, leading to frequent exposure to antibiotics. On the other hand, choices A, B, and C are less likely to develop resistance as rapidly as E. coli due to their lower frequency of exposure to antibiotics and differences in genetic makeup. Streptococcus pyogenes is susceptible to penicillin, Meningococcus has shown susceptibility to several antibiotics, and Treponema pallidum has limited exposure to antibiotics due to its unique nature as the causative agent of syphilis.

The patient complains of wetting when she sneezes. How should the nurse document this information?
- A. Nocturia
- B. Micturition
- C. Urge incontinence
- D. Stress incontinence
Correct Answer: D
Rationale: The correct answer is D: Stress incontinence. This type of incontinence is characterized by leakage of urine when there is increased intra-abdominal pressure, such as during sneezing or coughing. The nurse should document this information as stress incontinence to accurately describe the patient's symptoms. Nocturia (A) refers to waking up at night to urinate, not related to sneezing. Micturition (B) is the act of urination, not specific to the patient's symptoms. Urge incontinence (C) is characterized by a sudden and strong need to urinate, not triggered by sneezing.
Which of the following antibiotics is considered safe to use in newborn babies?
- A. Chloramphenicol
- B. Trimethoprim/Sulfamethoxazole
- C. Tetracyclines
- D. Ampicillin
Correct Answer: D
Rationale: The correct answer is D: Ampicillin. It is considered safe to use in newborn babies due to its efficacy against common bacterial infections in this age group. Ampicillin is a broad-spectrum antibiotic that is often prescribed for neonatal sepsis and meningitis. It is also well-tolerated and has minimal side effects in newborns.
A: Chloramphenicol is not recommended in newborns due to the risk of gray baby syndrome.
B: Trimethoprim/Sulfamethoxazole can cause kernicterus and other adverse effects in newborns.
C: Tetracyclines can lead to tooth discoloration and inhibit bone growth in newborns.
Which of the following antibiotics is considered safe to use in newborn * babies?
- A. Chloramphenicol
- B. Trimethoprim/Sulfamethoxazole
- C. Teracyclines
- D. Ampicillin
Correct Answer: D
Rationale: The correct answer is D: Ampicillin. Ampicillin is considered safe for use in newborn babies because it is a commonly used antibiotic in neonates and has a favorable safety profile. It is effective against a wide range of bacteria commonly found in newborns. Chloramphenicol (A) can cause serious side effects like gray baby syndrome. Trimethoprim/Sulfamethoxazole (B) is not recommended in newborns due to potential risks. Tetracyclines (C) can lead to tooth discoloration and bone growth inhibition in newborns.
Which of these statements is most appropriate when the nurse is obtaining a genitourinary history from an older man?
- A. Do you need to get up at night to urinate?
- B. Do you experience nocturnal emissions, or wet dreams?
- C. Do you know how to perform a testicular self-examination?
- D. Has anyone ever touched your genitals when you did not want them to?
Correct Answer: A
Rationale: The correct answer is A because it pertains to a common genitourinary issue in older men, nocturia. Nocturnal emissions (choice B) are not typically relevant in this context. Testicular self-examination (choice C) is more appropriate for younger men, and asking about unwanted touching (choice D) is not relevant to obtaining a genitourinary history. Asking about nocturia can provide valuable information about potential prostate issues, urinary tract infections, or other conditions commonly affecting older men.
Which of the following agents is indicated in a 25 year old female is diagnosed with genital herpes simplex virus infection?
- A. Amantadine
- B. Valacyclovir
- C. Lamivudine
- D. Zanamivir
Correct Answer: B
Rationale: The correct answer is B: Valacyclovir. Valacyclovir is a commonly prescribed antiviral medication used to treat genital herpes simplex virus infections. Firstly, it is a nucleoside analog that inhibits viral DNA replication, helping to reduce symptoms and prevent outbreaks. Additionally, Valacyclovir is well-tolerated and effective in managing herpes infections in young adults.
Choice A, Amantadine, is an antiviral primarily used for treating influenza A virus infections and is not effective against herpes simplex viruses. Choice C, Lamivudine, is an antiretroviral medication used to treat HIV and hepatitis B infections, not herpes simplex virus infections. Choice D, Zanamivir, is also an antiviral used for treating influenza infections and is not indicated for genital herpes simplex virus infections.
