1. A client is receiving vancomycin. Which of the following laboratory results should be monitored to evaluate the therapeutic effect of this medication?
- A. BUN
- B. Creatinine
- C. Hemoglobin
- D. White blood cell count
Correct answer: B
Rationale: Corrected Rationale: Creatinine levels should be monitored to evaluate vancomycin's effect on kidney function. Vancomycin can be nephrotoxic, so monitoring creatinine levels helps assess renal function and ensure that the medication is not causing harm to the kidneys. Monitoring BUN (choice A) is important for assessing kidney function but is not as specific as monitoring creatinine levels. Hemoglobin (choice C) and white blood cell count (choice D) are not directly related to evaluating the therapeutic effect of vancomycin.
2. A healthcare professional is planning to administer Morphine IV to a postoperative client. Which of the following actions should the healthcare professional take?
- A. Monitor for seizures and confusion with repeated doses.
- B. Protect the client's skin from severe diarrhea that occurs with morphine.
- C. Withhold this medication if the respiratory rate is less than 12/min.
- D. Administer Morphine intermittently via IV bolus over 30 seconds or less.
Correct answer: C
Rationale: The correct action the healthcare professional should take when administering Morphine IV to a postoperative client is to withhold the medication if the respiratory rate is less than 12/min. Respiratory depression is a common adverse effect of opioids like Morphine. Administering opioids when the respiratory rate is already compromised can further depress breathing, leading to life-threatening complications. Monitoring for seizures and confusion (Choice A) is not directly related to Morphine administration. Protecting the client's skin from severe diarrhea (Choice B) is not a common side effect of morphine. Administering Morphine via IV bolus (Choice D) should be done carefully but is not the most critical action in this scenario.
3. A nurse is teaching a client who has a new prescription for Spironolactone. Which of the following adverse effects should the nurse instruct the client to monitor?
- A. Hyperkalemia
- B. Hypoglycemia
- C. Hypocalcemia
- D. Hyponatremia
Correct answer: A
Rationale: Spironolactone is a potassium-sparing diuretic, so the nurse should monitor the client for hyperkalemia, which can cause muscle weakness and cardiac dysrhythmias.
4. A healthcare professional in a provider's office is monitoring serum electrolytes for four older adult clients who take digoxin. Which of the following electrolyte values increases a client's risk for Digoxin toxicity?
- A. Calcium 9.2 mg/dL
- B. Calcium 10.3 mg/dL
- C. Potassium 3.4 mEq/L
- D. Potassium 4.8 mEq/L
Correct answer: C
Rationale: The correct answer is C: Potassium 3.4 mEq/L. Potassium 3.4 mEq/L is below the expected reference range and puts a client at risk for digoxin toxicity. Low potassium levels can lead to fatal dysrhythmias, especially in older clients taking Digoxin, as potassium plays a crucial role in the heart's electrical activity. Choices A and B are related to calcium levels, which do not directly increase the risk of Digoxin toxicity. Choice D, Potassium 4.8 mEq/L, is within the expected reference range and would not increase the risk of Digoxin toxicity.
5. A healthcare professional is admitting a toddler to the hospital after an Acetaminophen overdose. Which of the following medications should the healthcare professional anticipate administering to this client?
- A. Acetylcysteine
- B. Pegfilgrastim
- C. Misoprostol
- D. Naltrexone
Correct answer: A
Rationale: The correct answer is Acetylcysteine. Acetylcysteine is the antidote for acetaminophen overdose. It works by replenishing glutathione, which is depleted in cases of acetaminophen overdose, thus preventing liver damage. Pegfilgrastim is a medication used to stimulate white blood cell production, misoprostol is a medication used to prevent gastric ulcers, and naltrexone is used in the management of opioid addiction and alcohol dependence, which are not indicated in the scenario described.
