1. What is the antidote for Warfarin?

• A. Vitamin D
• B. Vitamin C
• C. Vitamin K
• D. Vitamin B6

Correct answer: C

Rationale: Vitamin K is the antidote for Warfarin toxicity as it helps reverse the anticoagulant effects of Warfarin. Warfarin works by inhibiting vitamin K-dependent clotting factors, and administering vitamin K can replenish these factors, thereby counteracting the anticoagulant effects of Warfarin. Vitamin D, Vitamin C, and Vitamin B6 do not have the specific mechanism to counteract the anticoagulant effects of Warfarin, making them incorrect choices.

2. A client has a new prescription for a combination of oral NRTIs (abacavir, lamivudine, and zidovudine) for the treatment of HIV. Which of the following statements should the nurse include in teaching the client?

• A. These medications work by blocking HIV entry into cells.
• B. These medications work by weakening the cell wall of the HIV virus.
• C. These medications work by inhibiting enzymes to prevent HIV replication.
• D. These medications work by preventing protein synthesis within the HIV cell.

Correct answer: C

Rationale: The NRTI antiretroviral medications this client is prescribed work by inhibiting the enzyme reverse transcriptase, thus preventing HIV replication. By inhibiting this crucial enzyme, the drug interferes with the virus's ability to replicate and spread in the body. Choice A is incorrect because NRTIs do not block HIV entry into cells. Choice B is incorrect as NRTIs do not weaken the cell wall of the virus. Choice D is incorrect as NRTIs do not prevent protein synthesis within the HIV cell.

3. A healthcare professional is caring for a client who is prescribed Digoxin. Which of the following findings should the healthcare professional monitor to assess for potential toxicity?

• A. Bradycardia
• B. Hypertension
• C. Hypoglycemia
• D. Hypercalcemia

Correct answer: A

Rationale: The correct answer is A: Bradycardia. Bradycardia is a common sign of Digoxin toxicity. Digoxin can cause bradycardia due to its effects on the heart's electrical conduction system. Monitoring the client's heart rate regularly is essential to detect and manage toxicity promptly. Choice B, Hypertension, is incorrect as Digoxin toxicity typically presents with bradycardia and not hypertension. Choices C and D, Hypoglycemia and Hypercalcemia, are also incorrect as they are not typically associated with Digoxin toxicity.

4. A client who is receiving combination chemotherapy is exhibiting a temperature of 38.1°C (100.6°F). Which of the following findings should the nurse identify as an indication of an oncologic emergency?

• A. Dry oral mucous membranes
• B. Nausea and vomiting
• C. Temperature of 38.1°C (100.6°F)
• D. Anorexia

Correct answer: C

Rationale: A temperature of 38.1°C (100.6°F) can indicate an infection, which is considered an oncologic emergency in clients undergoing chemotherapy due to the heightened risk of sepsis in immunocompromised individuals. Immediate assessment and intervention are crucial to prevent severe complications. Dry oral mucous membranes, nausea and vomiting, and anorexia are common side effects of chemotherapy but are not specific indicators of an oncologic emergency like a fever in this setting.

5. A client with streptococcal pneumonia is receiving penicillin G by intermittent IV bolus. 10 minutes into the infusion of the third dose, the client reports itching at the IV site, dizziness, and shortness of breath. What should the nurse do first?

• A. Stop the infusion.
• B. Call the provider.
• C. Elevate the head of the bed.
• D. Auscultate breath sounds.

Correct answer: A

Rationale: In this scenario, the client is exhibiting signs of anaphylaxis, a severe allergic reaction. The priority action for the nurse is to stop the infusion immediately to prevent further administration of the allergen and worsening symptoms. Once the infusion is stopped, the nurse can then proceed with additional interventions, such as calling the provider, assessing the client's respiratory status, and providing appropriate care as needed.
