1. An older adult client has a new prescription for Digoxin and takes multiple other medications. The nurse should recognize that concurrent use of which of the following medications places the client at risk for Digoxin toxicity?
- A. Phenytoin
- B. Verapamil
- C. Warfarin
- D. Aluminum hydroxide
Correct answer: B
Rationale: Verapamil, a calcium-channel blocker, can increase digoxin levels, leading to toxicity. When given together, the digoxin dosage may need adjustment, and the nurse should closely monitor the client's digoxin levels to prevent toxicity symptoms such as nausea, vomiting, visual disturbances, and arrhythmias. The other choices, Phenytoin, Warfarin, and Aluminum hydroxide, do not significantly interact with Digoxin to cause toxicity. Phenytoin may reduce Digoxin levels, while Warfarin and Aluminum hydroxide have minimal interactions with Digoxin.
2. A client with chronic renal disease is receiving therapy with epoetin alfa. Which of the following laboratory results should the nurse review for an indication of a therapeutic effect of the medication?
- A. The leukocyte count
- B. The platelet count
- C. The hematocrit (Hct)
- D. The erythrocyte sedimentation rate (ESR)
Correct answer: C
Rationale: The correct answer is C: The hematocrit (Hct). Monitoring the hematocrit is essential to assess the therapeutic effect of epoetin alfa because this medication stimulates red blood cell production in clients with chronic renal disease. The leukocyte count (choice A) and platelet count (choice B) are not directly affected by epoetin alfa therapy. The erythrocyte sedimentation rate (ESR) (choice D) is a non-specific marker of inflammation and is not used to monitor the therapeutic effect of epoetin alfa.
3. When a nurse assesses a client's IV catheter insertion site and notes a hematoma, which of the following actions should the nurse take? (Select all that apply.)
- A. Stop the infusion.
- B. Apply alcohol to the insertion site.
- C. Apply warm compresses to the insertion site.
- D. Elevate the client's arm.
Correct answer: C
Rationale: When a nurse detects a hematoma at the IV catheter insertion site, applying warm compresses is beneficial as it can promote healing by enhancing circulation and reducing swelling. Elevating the client's arm helps in reducing edema, which can relieve pressure, pain, and further bleeding in the hematoma area. Stopping the infusion may be necessary in certain situations, but it is not a standard action for all hematoma cases. Applying alcohol to the insertion site is discouraged as it can cause irritation and may not aid in resolving the hematoma.
4. A client with HIV is starting therapy with zidovudine. The nurse should monitor the client for which of the following adverse effects of this medication?
- A. Fatigue
- B. Blurred vision
- C. Ringing in the ears
- D. Constipation
Correct answer: A
Rationale: Fatigue is a common adverse effect of zidovudine due to its impact on bone marrow, leading to anemia. Zidovudine is known to cause bone marrow suppression, resulting in decreased production of red blood cells and subsequent fatigue.
5. A client in the emergency department has Benzodiazepine toxicity due to an overdose. Which of the following actions is the nurse's priority?
- A. Administer flumazenil.
- B. Identify the client's level of orientation.
- C. Infuse IV fluids.
- D. Prepare the client for gastric lavage.
Correct answer: B
Rationale: In a situation where a client presents with Benzodiazepine toxicity, the priority action for the nurse is to assess the client. By identifying the client's level of orientation, the nurse can gather crucial information about the client's mental status, which is essential for determining the appropriate care and interventions needed. Administering flumazenil is used to reverse the effects of benzodiazepines but should be based on a comprehensive assessment. Infusing IV fluids and preparing for gastric lavage may be necessary interventions but should follow a thorough assessment of the client's condition to ensure proper prioritization of care.
