- A. Increase fluid intake.
- B. Refrain from taking nephrotoxic drugs.
- C. Take sedative medications.
- D. Maintain limited physical activity.
Correct Answer: D
Rationale: Step-by-step rationale for choosing option D:
1. Instruct the client to maintain limited physical activity to prevent contamination of the urine sample.
2. Physical activity can introduce bacteria from sweat or skin into the specimen, leading to inaccurate results.
3. By limiting physical activity, the client can ensure a clean-catch midstream urine sample for accurate testing.
4. Increasing fluid intake (option A), refraining from nephrotoxic drugs (option B), and taking sedative medications (option C) are not directly related to obtaining a clean-catch midstream urine specimen.

Which antibiotic course is inappropriate for clinical scenario?
- A. Acute simple cystitis - trimethoprim for 3 days in otherwise well young women.
- B. Acute uncomplicated pyelonephritis - gentamycin + amoxicillin IV initially followed by 7 days of Augmentin orally.
- C. Pregnancy associated cystitis - nitrofurantoin 5 mg QID for 14 days.
- D. Acute simple cystitis in male patients - Augmentin or trimethoprim for 14 days.
Correct Answer: B
Rationale: The correct answer is B because the antibiotic regimen for acute uncomplicated pyelonephritis should not include gentamycin due to its potential toxicity and nephrotoxicity. The initial use of IV gentamycin is not recommended for uncomplicated pyelonephritis. The combination of gentamycin and amoxicillin is not the standard treatment for this condition. Gentamycin should be reserved for more serious infections. The choice of Augmentin for 7 days orally is also not the standard of care for pyelonephritis. The other choices (A, C, D) are appropriate antibiotic regimens for the corresponding clinical scenarios.
During a vaginal examination of a 38-year-old woman, the nurse notices that the vulva and vagina are erythematous and edematous with thick, white, curdlike discharge adhering to the vaginal walls. The woman reports intense pruritus and thick white discharge from her vagina. The nurse knows that these history and physical examination findings are most consistent with which condition?
- A. Candidiasis
- B. Trichomoniasis
- C. Atrophic vaginitis
- D. Bacterial vaginosis
Correct Answer: A
Rationale: Step 1: The key clues in the question are thick, white, curdlike discharge, intense pruritus, erythematous, and edematous vulva and vagina.
Step 2: These symptoms are classic for candidiasis, a fungal infection caused by Candida species.
Step 3: Candidiasis commonly presents with thick, white discharge, itching, and inflamed vaginal tissues.
Step 4: Trichomoniasis (choice B) typically presents with frothy, greenish-yellow discharge and vaginal itching.
Step 5: Atrophic vaginitis (choice C) is more common in postmenopausal women and presents with thin, watery discharge and vaginal dryness.
Step 6: Bacterial vaginosis (choice D) presents with thin, grayish-white discharge and a fishy odor.
Step 7: Therefore, based on the symptoms described in the question, the correct answer is A: Candidiasis.
A gerontologic nurse is assessing a patient who has
- A. The patients suprapubic region is dull on percussion. numerous comorbid health problems. What assessment
- B. The patient is uncharacteristically drowsy. findings should prompt the nurse to suspect a UTI?
- C. The patient claims to void large amounts of urine 2 to Select all that apply.
- D. Food cravings
Correct Answer: B
Rationale: The correct answer is B because uncharacteristic drowsiness can be a sign of a urinary tract infection (UTI) in older adults. UTIs can present atypically in older adults with symptoms like confusion, lethargy, and drowsiness. The other choices are incorrect because:
A: A dull suprapubic region on percussion is not specific to UTI.
C: Voiding large amounts of urine is not a typical symptom of UTI.
D: Food cravings are not associated with UTI symptoms.
Which of the following would be examples of foods selected to lower the pH of urine?
- A. Milk
- B. Tea
- C. Apples
- D. Meat
Correct Answer: C
Rationale: The correct answer is C: Apples. Apples are acidic in nature, which can help lower the pH of urine. Consuming acidic foods can make the urine more acidic. Milk is alkaline, so it would raise the pH of urine. Tea can vary in acidity, but generally it is not chosen to lower urine pH. Meat is also not acidic and would not contribute to lowering urine pH. So, apples are the most suitable choice for lowering urine pH among the options provided.
Each kidney contains about a million and stored in the pituitary gland
- A. ADH plays a key role in the homeostatic filtration apparatus called: process called osmoregulation
- B. the distal tubule
- C. the proximal tubule
Correct Answer: A
Rationale: The correct answer is A: ADH plays a key role in the homeostatic filtration apparatus called the process called osmoregulation. ADH, or antidiuretic hormone, regulates water balance by controlling the permeability of the collecting duct in the kidney nephrons. This controls the concentration of urine produced. The other choices, B and C, refer to specific parts of the kidney tubules and are not related to the role of ADH in osmoregulation. Choice D is incomplete and does not provide any relevant information. Therefore, A is the correct choice as it directly relates to the function of ADH in maintaining water balance within the body.
