1. A client who is taking hydrochlorothiazide (HydroDIURIL, HCTZ) has been started on triamterene (Dyrenium) as well. The client asks the nurse why both medications are required. The nurse formulates a response, based on the understanding that:
- A. Both are weak potassium-losing diuretics.
- B. The combination of these medications prevents renal toxicity.
- C. Hydrochlorothiazide is less expensive, so using a combination of diuretics is cost-effective.
- D. Triamterene is a potassium-sparing diuretic, whereas hydrochlorothiazide is a potassium-losing diuretic.
Correct answer: D
Rationale: The combination of triamterene and hydrochlorothiazide is used because triamterene is a potassium-sparing diuretic, which helps retain potassium, while hydrochlorothiazide is a potassium-losing diuretic, which promotes potassium excretion. This combination helps balance potassium levels in the body, preventing imbalances that can occur when using potassium-losing diuretics alone.
2. A client is receiving an intravenous (IV) infusion of an antineoplastic medication. During the infusion, the client complains of pain at the insertion site. The nurse notes redness and swelling at the site, along with a slowed infusion rate. What is the appropriate action for the nurse to take?
- A. Notify the healthcare provider.
- B. Administer pain medication to reduce discomfort.
- C. Apply ice and maintain the infusion rate as prescribed.
- D. Elevate the extremity of the IV site and slow the infusion rate.
Correct answer: A
Rationale: When a client complains of pain at the IV insertion site, and there are signs of extravasation such as redness and swelling, it is crucial to notify the healthcare provider immediately. Extravasation of antineoplastic medications can cause tissue damage, pain, and necrosis if they escape into surrounding tissues. Prompt action is necessary to prevent further complications and ensure appropriate management of the situation. Administering pain medication, applying ice, or elevating the extremity are not appropriate actions in cases of suspected extravasation. These actions do not address the underlying issue of potential tissue damage and necrosis that can occur due to the leakage of antineoplastic medication.
3. In a client with chronic renal failure receiving epoetin alfa (Epogen, Procrit), which laboratory result would indicate a therapeutic effect of the medication?
- A. Hematocrit of 32%
- B. Platelet count of 400,000 cells/mm³
- C. White blood cell count of 6000 cells/mm³
- D. Blood urea nitrogen (BUN) level of 15 mg/dL
Correct answer: A
Rationale: A hematocrit of 32% indicates a therapeutic effect of epoetin alfa in a client with chronic renal failure. Epoetin alfa is used to treat anemia in these patients by stimulating red blood cell production, leading to an increase in the hematocrit level. Monitoring the hematocrit is essential to assess the response to epoetin alfa therapy.
4. The client has begun medication therapy with pancrelipase (Pancrease MT). The nurse evaluates that the medication is having the optimal intended benefit if which effect is observed?
- A. Weight loss
- B. Relief of heartburn
- C. Reduction of steatorrhea
- D. Absence of abdominal pain
Correct answer: C
Rationale: Pancrelipase (Pancrease MT) is a pancreatic enzyme replacement therapy used to aid digestion in clients with pancreatic insufficiency. One of the key goals of pancrelipase therapy is to reduce the amount of undigested fat in the stool, known as steatorrhea. Therefore, the nurse should evaluate the effectiveness of pancrelipase by looking for a reduction in steatorrhea, indicating improved digestion and absorption of fats.
5. The client with small cell lung cancer is being treated with etoposide (VePesid). The nurse assisting in caring for the client during its administration understands that which side effect is specifically associated with this medication?
- A. Alopecia
- B. Chest pain
- C. Pulmonary fibrosis
- D. Orthostatic hypotension
Correct answer: D
Rationale: The correct answer is 'D: Orthostatic hypotension.' Etoposide is associated with orthostatic hypotension, a sudden drop in blood pressure that can occur when transitioning from lying down to standing up. It is important for the nurse to monitor the client's blood pressure during the infusion to detect and manage this potential side effect.
