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.

A-50-year-old man has a history of frequent episodes of renal colic with high calcium renal stones. The most useful agent in the treatment of recurrent calcium stones is:
- A. Furosemide
- B. Spironolactone
- C. Hydrochlorothiazide
- D. Acetazolamide
Correct Answer: C
Rationale: Rationale: The correct answer is C: Hydrochlorothiazide. It is a thiazide diuretic that reduces calcium excretion, preventing stone formation. Furosemide (A) and spironolactone (B) do not target calcium excretion specifically. Acetazolamide (D) is a carbonic anhydrase inhibitor and not commonly used for calcium stones.
The main regulator of water reabsorption is
- A. renin
- B. angiotensin
- C. antidiuretic hormone
- D. aldosterone
Correct Answer: C
Rationale: The correct answer is C: antidiuretic hormone. Antidiuretic hormone (ADH) regulates water reabsorption in the kidneys by increasing permeability of the collecting ducts to water. This allows for reabsorption of more water back into the bloodstream, reducing urine output and maintaining water balance. Renin, angiotensin, and aldosterone are involved in regulating blood pressure and electrolyte balance, not specifically water reabsorption. Therefore, ADH is the main regulator of water reabsorption in the body.
What indicates to the nurse that a patient with AKI is in the recovery phase?
- A. A return to normal weight
- B. A urine output of 3700 mL/day
- C. Decreasing sodium and potassium levels
- D. Decreasing blood urea nitrogen (BUN) and creatinine levels
Correct Answer: B
Rationale: Step-by-step rationale for why choice B is correct:
1. A urine output of 3700 mL/day indicates improved kidney function.
2. Increased urine output signifies the kidneys are able to filter and excrete waste.
3. High urine output is a positive sign of recovery in AKI patients.
4. Monitoring urine output is crucial in assessing kidney function.
5. Return to normal weight (choice A) may not directly indicate kidney recovery.
6. Decreasing sodium and potassium levels (choice C) can be due to other factors.
7. Decreasing BUN and creatinine levels (choice D) are important but do not directly indicate the recovery phase in AKI patients.
The clinic nurse is preparing a plan of care for a
- A. What role The clinic nurse should recognize what type of will the nurse have in implementing a behavioral therapy incontinence? approach?
- B. Stress incontinence
- C. Provide medication teaching related to
- D. Reflex incontinence pseudoephedrine sulfat
Correct Answer: A
Rationale: The correct answer is A because the clinic nurse needs to recognize the role they will have in implementing a behavioral therapy approach for incontinence. This involves assessing, planning, implementing, and evaluating the behavioral interventions to help manage the condition effectively. Choice B is incorrect as it only identifies a type of incontinence without addressing the nurse's role in care. Choice C is incorrect as it focuses on medication teaching, which is not related to behavioral therapy. Choice D is incorrect as it specifically mentions a medication, pseudoephedrine sulfate, which is not relevant to implementing a behavioral therapy approach.
The nurse is performing a genital examination on a male patient and notices urethral drainage. When collecting urethral discharge for microscopic examination and culture, the nurse should:
- A. Ask the patient to urinate into a sterile cup.
- B. Ask the patient to obtain a specimen of semen.
- C. Insert a cotton-tipped applicator into the urethra.
- D. Compress the glans between the examiner’s thumb and forefinger, and collect any discharge.
Correct Answer: D
Rationale: The correct answer is D because gently compressing the glans between the thumb and forefinger can help express the urethral discharge for collection. This method minimizes contamination and ensures a proper sample for microscopic examination and culture.
A: Asking the patient to urinate into a cup would not capture the discharge.
B: Semen is not relevant for urethral discharge testing.
C: Inserting a cotton-tipped applicator into the urethra may cause trauma and is not recommended for collecting urethral discharge.
