An adhesion of the prepuce to the head of the penis, making it impossible to retract, is:
- A. Paraphimosis
- B. Phimosis
- C. Smegma
- D. Dyschezia
Correct Answer: B
Rationale: The correct answer is B: Phimosis. Phimosis is the adhesion of the prepuce to the head of the penis, leading to the inability to retract the foreskin. This condition can cause pain, difficulty urinating, and increased risk of infections. Paraphimosis (choice A) is the painful retraction of a foreskin that is stuck behind the glans. Smegma (choice C) is a buildup of dead skin cells and oils under the foreskin. Dyschezia (choice D) is difficulty in passing stools. In this case, phimosis best describes the situation of adhesion preventing foreskin retraction.

Which of the following is the most appropriate choice of treating * aspergillosis?
- A. Terbinan
- B. Amphotericin B
- C. Flucytosine
- D. Itraconazole
Correct Answer: B
Rationale: Answer B, Amphotericin B, is the most appropriate choice for treating aspergillosis due to its broad-spectrum antifungal activity, especially against Aspergillus species. It is often used for severe or systemic infections when other options are ineffective. Terbinafine (A) is more commonly used for dermatophyte infections, while Flucytosine (C) is typically used for certain yeast infections. Itraconazole (D) may be effective against some Aspergillus strains but is generally considered less effective than Amphotericin B for severe cases.
A patient has very high plasma uric acid and has high risk of developing acute uric acid nephropathy. Which of the following agent should be avoided?
- A. Ethacrynic acid
- B. Acetazolamide
- C. Hydrochlorothiazide
- D. Furosemide
Correct Answer: D
Rationale: The correct answer is D: Furosemide. Furosemide is a loop diuretic which can increase uric acid levels in the blood, potentially worsening the patient's condition. Ethacrynic acid (A) is also a loop diuretic and can have similar effects. Acetazolamide (B) is a carbonic anhydrase inhibitor and may increase urinary excretion of uric acid, which can be beneficial in this case. Hydrochlorothiazide (C) is a thiazide diuretic that can actually lower uric acid levels by increasing urinary excretion. Therefore, the best choice to avoid in a patient with high plasma uric acid and risk of acute uric acid nephropathy is furosemide.
A nurse is preparing a patient diagnosed with benign
- A. When about 80% of the nephrons are no longer prostatic hypertrophy (BPH) for a lower urinary tract functioning cystoscopic examination. The nurse informs the patient that the most common temporary complication
Correct Answer: A
Rationale: Rationale:
1. BPH can cause urinary symptoms.
2. Cystoscopy is a common diagnostic test.
3. Temporary complications include UTI or urinary retention.
4. BPH affects a significant number of nephrons.
5. Choice A aligns with BPH pathophysiology and common complications.
Summary:
- Choice A is correct due to BPH affecting nephrons and causing urinary symptoms leading to temporary complications like UTI. Other choices lack relevance to BPH or its complications.
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 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.
