1. Why does a nurse on an oncology unit verify a client's current cumulative lifetime dose of doxorubicin before administering it to a client with breast cancer?
- A. Excessive doxorubicin can result in myelosuppression.
- B. Exceeding the lifetime cumulative dose limit of doxorubicin may lead to extravasation.
- C. An excess amount of doxorubicin can lead to cardiomyopathy.
- D. Exceeding the lifetime cumulative dose limit of doxorubicin may cause red-tinged urine and sweat.
Correct answer: C
Rationale: Verifying the client's current cumulative lifetime dose of doxorubicin is necessary because excessive amounts of the medication can lead to cardiomyopathy, a serious and potentially life-threatening side effect. By monitoring the cumulative dose, healthcare providers can help prevent cardiotoxicity and ensure patient safety during treatment.
2. Which of the following diuretics inhibits sodium reabsorption in the kidneys while sparing K+ and hydrogen ions?
- A. Spironolactone
- B. Furosemide
- C. Hydrochlorothiazide
- D. Bumetanide
Correct answer: A
Rationale: Spironolactone is the correct answer as it is classified as a potassium-sparing diuretic. It works by inhibiting sodium reabsorption in the kidneys while promoting the retention of potassium and hydrogen ions. This mechanism of action helps in reducing fluid retention without causing excessive loss of potassium, which is a common side effect of other diuretics. Furosemide (choice B), Hydrochlorothiazide (choice C), and Bumetanide (choice D) are not correct as they are not potassium-sparing diuretics. Furosemide and Bumetanide are loop diuretics that inhibit sodium, potassium, and chloride reabsorption in the loop of Henle. Hydrochlorothiazide is a thiazide diuretic that inhibits sodium and chloride reabsorption in the distal convoluted tubule, leading to potassium loss.
3. 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.
4. A healthcare provider is educating a group of new parents about immunizations. The provider should instruct the parents that the series for which of the following vaccines is completed prior to the first birthday?
- A. Pneumococcal conjugate vaccine
- B. Meningococcal conjugate vaccine
- C. Varicella vaccine
- D. Rotavirus vaccine
Correct answer: D
Rationale: The correct answer is D, Rotavirus vaccine. The series for the Rotavirus vaccine is completed prior to the first birthday as it is only administered to infants less than 8 months of age. This vaccine provides protection against severe diarrhea and vomiting caused by rotavirus infection, which is common in infants and young children. Choices A, B, and C are incorrect because the series for these vaccines extends beyond the first birthday. Pneumococcal conjugate vaccine and Meningococcal conjugate vaccine are typically given in multiple doses up to 2 years of age, while the Varicella vaccine is usually administered between 12 to 15 months of age.
5. A client has been taking Sertraline for the past 2 days. Which of the following assessment findings should alert the nurse to the possibility that the client is developing Serotonin syndrome?
- A. Bruising
- B. Fever
- C. Abdominal pain
- D. Rash
Correct answer: B
Rationale: Fever is a key symptom of serotonin syndrome, a potentially serious condition that can occur with the use of SSRIs like Sertraline. Serotonin syndrome is characterized by excessive levels of serotonin in the body, leading to symptoms such as fever, agitation, confusion, tremors, and sweating. If a client on Sertraline presents with fever, the nurse should consider the possibility of serotonin syndrome and take appropriate actions such as notifying the healthcare provider and monitoring the client closely. Bruising, abdominal pain, and rash are not typically associated with serotonin syndrome and are more likely to be indicative of other conditions or side effects.
