The following topical antifungal drugs include all EXCEPT:
- A. Tolnaftate
- B. Crotamiton
- C. Terbinafine
- D. Ciclopirox
Correct Answer: B
Rationale: The correct answer is B: Crotamiton. Crotamiton is not a topical antifungal drug; it is a scabicidal and antipruritic agent used to treat scabies and itching. Tolnaftate (A), Terbinafine (C), and Ciclopirox (D) are all topical antifungal drugs used to treat various fungal skin infections. Tolnaftate is commonly used for athlete's foot, ringworm, and jock itch. Terbinafine is effective against fungal infections like athlete's foot and ringworm. Ciclopirox is used to treat fungal infections like athlete's foot and ringworm as well.

The commonest type of ureteric calculus is
- A. calcium oxalate
- B. triple phosphate
- C. urate
- D. cysteine
Correct Answer: A
Rationale: The correct answer is A: calcium oxalate. This is because calcium oxalate stones are the most common type of ureteric calculus, accounting for around 75% of cases. They form due to an excess of calcium and oxalate in the urine. Triple phosphate stones (choice B) are more commonly found in the bladder and are associated with urinary tract infections. Urate stones (choice C) are less common and typically seen in patients with gout or acidic urine. Cysteine stones (choice D) are rare and usually seen in patients with a genetic disorder affecting cysteine metabolism.
A geriatric nurse is performing an assessment of body patient whose renal function is progressively declining. systems on an 85-year-old patient. The nurse should be
- A. related change affecting the renal or following situations? urinary system?
- B. When the patients creatinine level drops below 1.2
- C. Increased ability to concentrate urine
- D. Increased bladder capacity
Correct Answer: A
Rationale: The correct answer is A because as renal function declines in an elderly patient, there will be related changes affecting the urinary system. This is important for the nurse to assess to monitor the patient's renal health and intervene as necessary. Choice B is incorrect because a decrease in creatinine level is not a typical indicator of declining renal function. Choice C is incorrect because with declining renal function, the ability to concentrate urine actually decreases. Choice D is incorrect because increased bladder capacity is not a direct result of declining renal function.
A 45-year-old mother of two children is seen at the clinic for complaints of “losing my urine when I sneeze.†The nurse documents that she is experiencing:
- A. Urinary frequency.
- B. Enuresis.
- C. Stress incontinence.
- D. Urge incontinence.
Correct Answer: C
Rationale: The correct answer is C: Stress incontinence. This type of incontinence is characterized by leakage of urine during activities that increase intra-abdominal pressure, such as sneezing, coughing, or laughing. In this case, the woman is experiencing urine loss specifically when she sneezes, which aligns with the definition of stress incontinence. Other choices are incorrect because urinary frequency (choice A) refers to a frequent need to urinate, enuresis (choice B) is involuntary urination during sleep, and urge incontinence (choice D) is the sudden, strong need to urinate followed by involuntary leakage.
A 70 year old man requires treatment with an alpha-blocker for overflow incontinence due to enlarged prostate. Which of the following alpha blocking drugs is most appropriate drug to prescribe that will not affect his blood pressure significantly?
- A. Prazosin
- B. Phentolamine
- C. Tamsulosin
- D. Terazosin
Correct Answer: C
Rationale: The correct answer is C: Tamsulosin. It is the most appropriate alpha-blocker for the elderly man with enlarged prostate and overflow incontinence because of its selective action on alpha-1A receptors in the prostate, leading to relaxation of smooth muscle without significantly affecting blood pressure.
Rationale:
1. Prazosin (Choice A) and Terazosin (Choice D) are non-selective alpha-blockers that can cause significant blood pressure lowering due to their action on alpha-1 receptors in blood vessels, which may not be suitable for this patient.
2. Phentolamine (Choice B) is also a non-selective alpha-blocker that can lead to significant blood pressure reduction, making it unsuitable for this patient.
3. Tamsulosin (Choice C) is a selective alpha-1A blocker, primarily acting on the prostate, with minimal impact on blood pressure, making it the most appropriate choice for this patient.
The nurse is caring for a patient who underwent with renal calculi. The nurse should instruct the patient to percutaneous lithotripsy earlier in the day. What increase fluid intake to a level where the patient instruction should the nurse give the patient? produces at least how much urine each day?
- A. Limit oral fluid intake for 1 to 2 days.
- B. 1,250 mL
- C. Report the presence of fine, sand like particles
- D. 2,000 mL
Correct Answer: D
Rationale: The correct answer is D (2,000 mL). Adequate fluid intake helps prevent renal calculi formation and aids in flushing out the stone fragments post-lithotripsy. A daily urine output of at least 2,000 mL is recommended to prevent urinary stasis and stone recurrence. Choice A is incorrect as limiting fluid intake can lead to dehydration and hinder stone passage. Choice B is insufficient to ensure proper hydration. Choice C is incorrect as sand-like particles may be expected post-lithotripsy and do not indicate adequate fluid intake.
