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.

A client who takes Chlorpromazine for the treatment of Schizophrenia is due for a follow-up assessment. The nurse should expect the greatest improvement in which of the following manifestations? (Select all that apply.)
- A. Disorganized speech.
- B. Bizarre behavior.
- C. Impaired social interactions.
- D. Hallucinations.
Correct Answer: A
Rationale: When a client takes a conventional antipsychotic medication like chlorpromazine, the greatest improvement is typically seen in positive symptoms such as disorganized speech. These medications are more effective in managing positive symptoms like disorganized speech rather than negative symptoms like impaired social interactions or hallucinations. Therefore, the nurse should anticipate improvement in disorganized speech as a positive response to chlorpromazine treatment.

The nurse is preparing to give a potassium supplement. Which laboratory test should be checked before the patient receives a dose of potassium?
- A. Complete blood count
- B. Serum potassium level
- C. Serum sodium level
- D. Liver function studies
Correct Answer: B
Rationale: Before administering a potassium supplement to a patient, it is crucial to check the patient's serum potassium level. This is because if the serum potassium level is already elevated or within the high end of the normal range, giving additional potassium could lead to hyperkalemia, which can be life-threatening. Conversely, if the serum potassium level is low (hypokalemia), then administering potassium supplementation may be necessary to correct the deficiency. Monitoring the serum potassium level helps ensure safe and effective treatment with potassium supplements. It is a critical part of assessing the patient's electrolyte balance and overall health status.
What should a patient avoid while taking Angiotensin-converting enzymes?
- A. Salt substitutes
- B. Foods high in potassium
- C. Foods high in sodium
- D. All of the above
Correct Answer: A
Rationale: Patients taking Angiotensin-converting enzyme (ACE) inhibitors should avoid salt substitutes because they can contain potassium chloride, which may lead to hyperkalemia. It is important to restrict potassium-rich foods while on ACE inhibitors, but the primary concern with salt substitutes is their potassium content.
A client has a prescription for Heparin. Which of the following laboratory tests should be monitored while the client is receiving Heparin?
- A. Prothrombin time (PT)
- B. Complete blood count (CBC)
- C. International normalized ratio (INR)
- D. Activated partial thromboplastin time (aPTT)
Correct Answer: D
Rationale: Activated partial thromboplastin time (aPTT) is the correct laboratory test to monitor while a client is receiving Heparin. This test is used to assess the therapeutic levels of heparin in the blood, ensuring that the dose is within the safe and effective range. Monitoring aPTT helps healthcare providers adjust the dosage of Heparin to prevent complications such as bleeding or clotting.
