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. A nurse is caring for a client who has cirrhosis. Which of the following findings should the nurse expect?
- A. Decreased bilirubin levels
- B. Decreased prothrombin time
- C. Decreased albumin levels
- D. Increased prothrombin time
Correct answer: D
Rationale: In clients with cirrhosis, the liver is unable to produce clotting factors efficiently, leading to impaired clotting function. Therefore, an increased prothrombin time is expected in cirrhosis. Choices A, B, and C are incorrect. Decreased bilirubin levels are not typically seen in cirrhosis; prothrombin time is usually increased, not decreased; and albumin levels are often decreased in cirrhosis due to reduced synthetic liver function.
3. The nurse supervises care of a client in Buck’s traction. The nurse determines that care is appropriate if which of the following is observed? (Select all that apply)
- A. The nurse removes the foam boot three times per day to inspect the skin
- B. The staff turn the client to the unaffected side
- C. The staff turn the client to the unaffected side and the nurse asks the client to dorsiflex the foot on the affected leg
- D. The nurse asks the client to dorsiflex the foot on the affected leg
Correct answer: C
Rationale: Correct care for a client in Buck’s traction includes turning the client to the unaffected side to prevent complications such as pressure ulcers. Additionally, asking the client to dorsiflex the foot on the affected leg helps prevent foot drop. Removing the foam boot three times per day to inspect the skin is unnecessary and could disrupt the traction, so it is not appropriate. Therefore, choices A and D are incorrect.
4. A client with preeclampsia and postpartum hemorrhage is being cared for by a nurse. The nurse should recognize that which of the following medications is contraindicated?
- A. Methylergonovine
- B. Misoprostol
- C. Dinoprostone
- D. Oxytocin
Correct answer: A
Rationale: The correct answer is A, Methylergonovine. Methylergonovine is contraindicated in clients with preeclampsia due to the risk of hypertension. Misoprostol (choice B), Dinoprostone (choice C), and Oxytocin (choice D) are appropriate medications for managing postpartum hemorrhage and are not contraindicated in clients with preeclampsia.
5. A nurse is assessing a client who has a urinary tract infection and is receiving ciprofloxacin. Which of the following findings should the nurse report to the provider?
- A. Dry mouth.
- B. Photosensitivity.
- C. Headache.
- D. Urinary retention.
Correct answer: B
Rationale: The correct answer is B: Photosensitivity. Ciprofloxacin can cause photosensitivity, making the client more sensitive to sunlight. It is essential for the nurse to report this finding to the provider so that appropriate measures can be taken to prevent skin damage. Dry mouth, headache, and urinary retention are not typically associated with ciprofloxacin use and do not require immediate reporting to the provider in this scenario.
