PN ATI Capstone Proctored Comprehensive Assessment 2020 B
1. A client has been prescribed phenytoin. Which of the following should the nurse monitor to prevent toxicity?
- A. Blood pressure
- B. Complete blood count
- C. Serum phenytoin levels
- D. Liver function tests
Correct answer: C
Rationale: Corrected Rationale: Serum phenytoin levels should be regularly monitored to prevent toxicity because the therapeutic range is narrow. Monitoring blood pressure (choice A), complete blood count (choice B), and liver function tests (choice D) are not directly related to preventing phenytoin toxicity.
2. A nurse is caring for a client who has an indwelling urinary catheter. What should the nurse identify as a catheter occlusion?
- A. Pain during urination
- B. Bladder distention
- C. Cloudy urine
- D. Blood in the catheter tube
Correct answer: B
Rationale: The correct answer is B: Bladder distention. Bladder distention indicates that the bladder is full and there is impaired elimination, which could be caused by catheter occlusion. Pain during urination (choice A) is not typically associated with catheter occlusion but may indicate a urinary tract infection. Cloudy urine (choice C) can be a sign of infection but is not specific to catheter occlusion. Blood in the catheter tube (choice D) may indicate trauma during catheter insertion but is not a typical finding in catheter occlusion.
3. A nurse is caring for a client prescribed hydromorphone for severe pain. The client's respiratory rate has decreased from 16 breaths per minute to 6. Which of the following medications should the nurse prepare to administer?
- A. Naloxone
- B. Flumazenil
- C. Activated charcoal
- D. Aluminum hydroxide
Correct answer: A
Rationale: Naloxone is the correct answer. Naloxone is the antidote for opioid overdose, including hydromorphone. Opioids can cause respiratory depression, and a significant decrease in respiratory rate from 16 to 6 breaths per minute indicates respiratory compromise. Naloxone should be administered promptly to reverse the effects of the opioid and restore normal respiratory function. Flumazenil (Choice B) is used to reverse the effects of benzodiazepines, not opioids. Activated charcoal (Choice C) is used for gastrointestinal decontamination in cases of overdose with certain substances, but it is not the appropriate intervention for opioid-induced respiratory depression. Aluminum hydroxide (Choice D) is an antacid and has no role in managing opioid overdose or respiratory depression.
4. A healthcare professional is caring for a client receiving potassium-sparing diuretics. Which of the following should the healthcare professional monitor?
- A. Hypokalemia
- B. Hyperkalemia
- C. Hypoglycemia
- D. Hyponatremia
Correct answer: B
Rationale: Corrected Rationale: When a client is receiving potassium-sparing diuretics, the healthcare professional should monitor for hyperkalemia. Potassium-sparing diuretics can cause potassium retention, leading to elevated potassium levels in the blood. Monitoring potassium levels is crucial to prevent hyperkalemia-related complications such as cardiac arrhythmias. Choices A, C, and D are incorrect because potassium-sparing diuretics typically do not cause hypokalemia, hypoglycemia, or hyponatremia.
5. A healthcare professional is assessing a client for signs of dehydration. Which of the following findings should the healthcare professional look for?
- A. Edema
- B. Dry mucous membranes
- C. Weight gain
- D. Increased urination
Correct answer: B
Rationale: Dry mucous membranes are a classic sign of dehydration. In dehydration, the body loses more water than it takes in, leading to dryness of mucous membranes like the mouth and throat. Edema (choice A) is swelling caused by excess fluid trapped in the body's tissues, which is not a typical sign of dehydration. Weight gain (choice C) is also not a common sign of dehydration; in fact, dehydration usually leads to weight loss. Increased urination (choice D) is more indicative of conditions like diabetes or diuretic use, not dehydration.
