2. Incorrect Choices:
A. Vancomycin - Acts on cell wall synthesis, not folate synthesis.
B. Linezolid - Inhibits protein synthesis, not folate synthesis.
D. Penicillin - Inhibits cell wall synthesis, not folate synthesis.

A 45-year-old woman is seeking advice on contraception. She is considering using an intrauterine device (IUD). The nurse should inform her that the IUD is effective for:
- A. 5 to 10 years.
- B. 1 to 2 years.
- C. 3 to 5 years.
- D. Indefinitely.
Correct Answer: A
Rationale: The correct answer is A: 5 to 10 years. IUDs are long-acting reversible contraceptives effective for 5 to 10 years depending on the type. Hormonal IUDs last around 5 years, while copper IUDs can last up to 10 years. This extended duration provides reliable contraception for an extended period with minimal user intervention.
Choice B: 1 to 2 years is incorrect because IUDs have a longer duration of effectiveness.
Choice C: 3 to 5 years is incorrect as it falls short of the typical duration of effectiveness for most IUD types.
Choice D: Indefinitely is incorrect as IUDs do have a maximum effective period, after which they need to be removed or replaced.
A patient calls the clinic for instructions before having a Papanicolaou (Pap) smear. The most appropriate instructions from the nurse are:
- A. If you are menstruating, please use pads to avoid placing anything into the vagina.
- B. Avoid intercourse, inserting anything into the vagina, or douching within 24 hours of your appointment.
- C. If you suspect that you have a vaginal infection, please gather a sample of the discharge to bring with you.
- D. We would like you to use a mild saline douche before your examination. You may pick this up in our office.
Correct Answer: B
Rationale: The correct answer is B because avoiding intercourse, inserting anything into the vagina, or douching within 24 hours of the appointment helps ensure an accurate Pap smear result. Intercourse, vaginal products, and douching can introduce foreign substances or disrupt the natural vaginal flora, potentially affecting the test results. Option A is incorrect because using pads during menstruation is a general recommendation and not specific to a Pap smear appointment. Option C is incorrect because bringing a sample of discharge is not necessary for a Pap smear. Option D is incorrect because douching is not recommended before a Pap smear as it can alter the vaginal environment.
A 23 year old pregnant woman has UTI and presents to the ER with fever, frequency and urgency. Which of the following antibiotics can cause potential harm to her fetus?
- A. Nitrofurantoin
- B. Amoxicillin
- C. Gentamycin
- D. Cephalexin
Correct Answer: C
Rationale: The correct answer is C: Gentamycin. Gentamycin is known to have potential harmful effects on the fetus, such as causing hearing loss and kidney damage. This is due to its ability to cross the placental barrier. Amoxicillin (B) and Cephalexin (D) are both considered safe for use in pregnancy and are commonly prescribed for UTIs. Nitrofurantoin (A) is typically avoided in the third trimester due to the risk of hemolytic anemia in the newborn, but it is considered safe earlier in pregnancy. Therefore, Gentamycin is the correct choice as it poses a higher risk to the fetus compared to the other antibiotics.
Which of the following drug that acts by inhibiting HIV protease enzyme?
- A. Lamivudine
- B. Efavirenz
- C. Stavudine
- D. Ritonavir
Correct Answer: D
Rationale: Rationale:
1. Ritonavir is a protease inhibitor used in HIV treatment.
2. It works by inhibiting the HIV protease enzyme, preventing viral replication.
3. Lamivudine, Efavirenz, and Stavudine are not protease inhibitors but work through different mechanisms.
4. Lamivudine is a nucleoside reverse transcriptase inhibitor, Efavirenz is a non-nucleoside reverse transcriptase inhibitor, and Stavudine is another nucleoside reverse transcriptase inhibitor.
Summary:
Ritonavir is the correct answer as it directly targets the HIV protease enzyme, unlike the other options which act on reverse transcriptase enzymes.
A patient with a sacral pressure ulcer has had a

- B. As a result of this new consequent of antibiotic therapy intervention, the nurse should prioritize what nursing
- C. The need to expect a heavy menstrual period diagnosis in the patients plan of care?
- D. Impaired physical mobility related to presence of an
Correct Answer: E
Rationale: Step-by-step rationale for the correct answer (E):
1. The prompt mentions a patient with a sacral pressure ulcer.
2. Considering the context, the most relevant issue would be wound care and prevention of pressure ulcers.
3. Option E is the only choice related to wound care and prevention, indicating the correct focus for the nurse.
4. Choices A, B, C, and D are unrelated to the primary concern of managing the sacral pressure ulcer.
5. Therefore, E is the correct answer as it aligns with the patient's immediate care needs.
