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.

Which of the following semisynthetic penicillins which has an extended spectrum of activity against many gram negative bacilli, is acid resistant but not penicillinase resistant?:
- A. Cloxacillin
- B. Amoxicillin
- C. Phenoxymethyl penicillin
- D. Piperacillin
Correct Answer: B
Rationale: The correct answer is B: Amoxicillin. This penicillin has an extended spectrum of activity against gram-negative bacilli, making it effective against a wider range of bacteria. It is acid-resistant, allowing it to be taken orally, but it is not penicillinase-resistant, meaning it can be easily degraded by beta-lactamase enzymes.
A: Cloxacillin is penicillinase-resistant but does not have an extended spectrum against gram-negative bacilli.
C: Phenoxymethyl penicillin is not acid-resistant and does not have an extended spectrum against gram-negative bacilli.
D: Piperacillin has an extended spectrum of activity but is not acid-resistant and is susceptible to penicillinase.
"Red man syndrome "has been associated with rapid intravenous injection of * which of the following antibiotic?
- A. Vancomycin
- B. Clindamycin
- C. Cefoperazone
- D. Piperacillin
Correct Answer: A
Rationale: The correct answer is A: Vancomycin. Red man syndrome is a hypersensitivity reaction caused by rapid infusion of vancomycin. Vancomycin infusion releases histamine, leading to flushing, rash, and hypotension. Clindamycin (B), Cefoperazone (C), and Piperacillin (D) are not associated with red man syndrome. Clindamycin can cause pseudomembranous colitis, Cefoperazone can cause bleeding disorders, and Piperacillin can cause hypersensitivity reactions, but not red man syndrome.
A 25-year-old woman is concerned about the possibility of an STI. The nurse asks about her sexual history and recommends that she be tested for sexually transmitted infections (STIs). Which of the following STIs can be detected through a Pap smear?
- A. Chlamydia.
- B. Gonorrhea.
- C. Trichomoniasis.
- D. HPV.
Correct Answer: C
Rationale: The correct answer is C: Trichomoniasis. A Pap smear can detect abnormal changes in the cervix caused by Trichomoniasis, which is a common STI. The test can identify the presence of the parasite Trichomonas vaginalis. The other choices, A: Chlamydia, B: Gonorrhea, and D: HPV, cannot be detected through a Pap smear as they require specific tests such as urine tests, swab tests, or blood tests. Chlamydia and Gonorrhea are bacterial infections, while HPV is a viral infection that can lead to cervical cancer but is not detectable through a Pap smear alone.
The nurse is reviewing the electronic health record of
- A. The nurse reads that the physician assessed the patients deep tendon reflexes. What condition of the urinary/renal system does this assessment address?
- B. Renal calculi
- C. Bladder dysfunction
- D. Benign prostatic hyperplasia (BPH)
Correct Answer: B
Rationale: The correct answer is B: Renal calculi. Deep tendon reflex assessment is not directly related to the urinary/renal system. Renal calculi, or kidney stones, can cause severe pain and discomfort in the urinary tract. The assessment may help identify if the patient is experiencing symptoms related to renal calculi, such as flank pain or hematuria. Choices A, C, and D are incorrect because they are not specifically addressed by assessing deep tendon reflexes, unlike renal calculi.
The mother of a 10-year-old boy asks the nurse to discuss the recognition of puberty. The nurse should reply by saying:
- A. Puberty usually begins around 15 years of ag
- C. The first sign of puberty is an enlargement of the testes.
- D. The penis size does not increase until about 16 years of ag
Correct Answer: C
Rationale: The correct answer is C because the first sign of puberty in boys is typically an enlargement of the testes due to increased testosterone production. This occurs around age 10-14. Choice A is incorrect as puberty usually begins around 10-14 years of age. Choice D is incorrect as penis growth usually starts during puberty, not at 16.
