Question 1 of 5
A client comes to the clinic with reports of dysuria and frequency. The nurse practitioner suspects that the client is experiencing a UTI. Which laboratory testing would be most important?
Correct Answer: A
Rationale: The correct answer is A: Urinalysis. This is the most important test because it can detect the presence of bacteria, white blood cells, and nitrites in the urine, which are indicative of a UTI. Urinalysis also provides information on the urine pH and specific gravity.
Choice B, Chest X-ray, is not relevant to diagnosing a UTI.
Choice C, Blood culture, is used to identify bacteria in the bloodstream, not in the urinary tract.
Choice D, Complete blood count (CB
C), may show signs of infection but does not directly identify a UTI.
Question 2 of 5
Which of the following is an important teaching point for a patient prescribed oxybutynin?
Correct Answer: A
Rationale: The correct answer is A: Increase fluid intake to prevent dehydration. Oxybutynin is an anticholinergic medication commonly prescribed for overactive bladder. It can cause dry mouth and increase the risk of dehydration. Instructing the patient to increase fluid intake will help prevent dehydration and minimize side effects. Option B is incorrect as high-fiber foods can actually help prevent constipation, a common side effect of oxybutynin. Option C is incorrect because experiencing dizziness is a common side effect that may improve over time, and stopping the medication abruptly can lead to worsening of symptoms. Option D is incorrect as oxybutynin can be taken with or without food.
Question 3 of 5
What is the highest priority nursing diagnosis for a client with a history of urinary urgency who is taking oxybutynin (Ditropan)?
Correct Answer: D
Rationale: The correct answer is D: Risk for altered comfort: dry mouth. Oxybutynin is an anticholinergic medication that can cause side effects like dry mouth. Prioritizing the nursing diagnosis of altered comfort related to dry mouth is essential to address the client's immediate discomfort and potential impact on oral health.
Choice A is incorrect because urinary urgency is not directly related to impaired urinary elimination.
Choices B and C are unrelated to the client's current situation.
Therefore, the highest priority is addressing the client's discomfort due to dry mouth.
Question 4 of 5
The nurse is describing how oxybutynin exerts its effect to a client receiving it as treatment for overactive bladder. An understanding of which receptor would the nurse integrate into the description?
Correct Answer: C
Rationale: The correct answer is C: Muscarinic receptors. Oxybutynin is an anticholinergic medication that works by blocking muscarinic receptors in the bladder muscle, leading to relaxation of the bladder muscle and decreased bladder contractions. This helps to reduce the symptoms of overactive bladder.
Choices A, B, and D are incorrect because oxybutynin does not primarily act on dopamine, beta adrenergic, or alpha adrenergic receptors. Selecting these receptors would not accurately explain how oxybutynin exerts its therapeutic effect in treating overactive bladder.
Question 5 of 5
The nurse priority assessment for a child with recurrent UTI will include: (Select All that Apply.)
Correct Answer: A,C,F
Rationale: The correct answers for the nurse priority assessment for a child with recurrent UTI are A, C, and F. A, Checking for abdominal tenderness, is crucial to assess for possible kidney involvement. C, Obtaining a urine culture, is essential to identify the causative organism for appropriate treatment. F, Assessing for congenital structural abnormalities, is important as they can predispose a child to recurrent UTIs. Monitoring for signs of jaundice (
B) is not directly related to UTIs. Assessing for potential sexual abuse (
D) is important but not a priority in this case. Assessing the child's sleep patterns (E) and evaluating the child's bowel movement frequency (G) are not directly relevant to UTI assessment.
