1. What is the therapeutic use of Phenytoin?
- A. Replacement in hypothyroidism to restore normal hormonal balance
- B. Diminished accumulation of acid in the gastric lumen with lessened gastroesophageal reflux
- C. Diminished seizure activity, termination of ventricular arrhythmias
- D. Prevention of thrombus formation, prevention of extension of existing thrombi
Correct answer: C
Rationale: Phenytoin is primarily used to diminish seizure activity and is effective in terminating ventricular arrhythmias. It works by stabilizing neuronal membranes, reducing repetitive neuronal firing, and limiting the spread of seizure activity in the brain. While phenytoin does not have a direct role in preventing thrombus formation or extending existing thrombi, it is crucial in managing seizures and certain arrhythmias.
2. A healthcare professional is preparing to administer IV Vancomycin to a client who has a systemic infection. Which of the following actions should the healthcare professional take?
- A. Administer the medication rapidly over 15 minutes.
- B. Monitor the client for hypertension during infusion.
- C. Administer a test dose before the full dose.
- D. Monitor the client for Red Man Syndrome.
Correct answer: D
Rationale: The correct action for the healthcare professional is to monitor the client for Red Man Syndrome. Red Man Syndrome is a common adverse reaction to Vancomycin characterized by flushing, rash, and hypotension. It is important to monitor the client for these symptoms to intervene promptly if they occur.
3. A client with breast cancer is receiving cyclophosphamide. What finding should the nurse monitor for?
- A. Hypertension
- B. Hyperglycemia
- C. Ototoxicity
- D. Hemorrhagic cystitis
Correct answer: D
Rationale: When a client is receiving cyclophosphamide, the nurse should monitor for hemorrhagic cystitis, a severe adverse effect caused by bladder irritation. It is essential to watch for signs such as hematuria, dysuria, and urinary frequency, and promptly intervene to prevent further complications. Hypertension (Choice A) is not typically associated with cyclophosphamide use. Hyperglycemia (Choice B) is not a common side effect of cyclophosphamide. Ototoxicity (Choice C) is more commonly associated with medications like aminoglycoside antibiotics or high-dose aspirin.
4. A client has a new prescription for Hydralazine. Which of the following adverse effects should the nurse instruct the client to monitor?
- A. Tachycardia
- B. Hyperglycemia
- C. Hyponatremia
- D. Constipation
Correct answer: A
Rationale: Corrected Rationale: Hydralazine is a vasodilator that can cause reflex tachycardia as an adverse effect. The client should monitor their pulse and report any significant increases, as tachycardia can indicate a severe adverse reaction to the medication. Choice B, Hyperglycemia, is not a common adverse effect of Hydralazine. Choice C, Hyponatremia, and Choice D, Constipation, are also not typically associated with Hydralazine use. Therefore, the correct answer is A: Tachycardia.
5. A client is receiving Gentamicin. Which of the following laboratory values should the nurse monitor to assess for nephrotoxicity?
- A. Serum sodium.
- B. Serum creatinine.
- C. Serum potassium.
- D. Serum glucose.
Correct answer: B
Rationale: When a client is receiving Gentamicin, the nurse should monitor serum creatinine levels to assess for nephrotoxicity. Gentamicin is known to potentially cause nephrotoxicity, leading to impaired kidney function. Monitoring serum creatinine levels helps in early detection of any kidney damage or dysfunction. Serum sodium, serum potassium, and serum glucose levels are not directly related to nephrotoxicity caused by Gentamicin, so they are not the appropriate values to monitor in this case.
