1. Why is prostaglandin E1 prescribed for a child with transposition of the great arteries?
- A. Prevents hypercyanotic (blue or tet) spells
- B. Maintains an adequate hormone level
- C. Maintains the position of the great arteries
- D. Provides adequate oxygen saturation and maintains cardiac output
Correct answer: D
Rationale: Prostaglandin E1 is prescribed for a child with transposition of the great arteries to increase blood mixing, which helps maintain adequate oxygen saturation and cardiac output. This medication does not prevent hypercyanotic spells, maintain hormone levels, or influence the position of the great arteries.
2. A client presenting with complaints of not feeling well is seen in a clinic. The client is taking several medications for the control of heart disease and hypertension, including a beta-blocker, digoxin (Lanoxin), and a diuretic. A tentative diagnosis of digoxin toxicity is made. Which of the following assessment data would support this diagnosis?
- A. Dyspnea, edema, and palpitations
- B. Chest pain, hypotension, and paresthesia
- C. Double vision, loss of appetite, and nausea
- D. Constipation, dry mouth, and sleep disorder
Correct answer: C
Rationale: The correct answer is C. Double vision, loss of appetite, and nausea are classic signs of digoxin toxicity. Other signs may include bradycardia, visual disturbances, and confusion. These symptoms are indicators that the client may be experiencing adverse effects due to elevated levels of digoxin in the system, requiring immediate medical attention to prevent serious complications.
3. 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.
4. The client with breast cancer is receiving cyclophosphamide (Neosar). The nurse is reinforcing medication instructions and advises the client to:
- A. Take the medication with food.
- B. Increase fluid intake to 2000 to 3000 mL daily.
- C. Decrease sodium intake while taking the medication.
- D. Increase potassium intake while taking the medication.
Correct answer: B
Rationale: The correct answer is to increase fluid intake to 2000 to 3000 mL daily. Cyclophosphamide can cause hemorrhagic cystitis as a toxic effect. By increasing fluid intake, the client can help prevent this complication by promoting frequent urination, which reduces the concentration of the drug and its metabolites in the bladder. This dilution effect can help reduce the risk of bladder toxicity.
5. A client with a prescription to take theophylline (Theo-24) daily has been given medication instructions by the nurse. The nurse determines that the client needs further information about the medication if the client states that he or she will:
- A. Drink at least 2 L of fluid per day.
- B. Take the daily dose at bedtime.
- C. Avoid changing brands of the medication without health care provider (HCP) approval.
- D. Avoid over-the-counter (OTC) cough and cold medications unless approved by the HCP.
Correct answer: B
Rationale: The correct answer is B. Taking theophylline at bedtime is inappropriate because it can cause insomnia. The medication should be taken early in the morning to avoid disrupting sleep patterns. It is important to follow the healthcare provider's instructions regarding the timing of the medication to achieve optimal therapeutic effects.
