Nursing Elites

1. Which of the following is the primary site of activity for the drug Warfarin?

• A. Kidney
• B. Liver
• C. Blood
• D. Heart

Correct answer: B

Rationale: Warfarin primarily affects the liver where it inhibits the synthesis of clotting factors.

2. When administering digoxin (Lanoxin) to a patient, the healthcare provider observes various signs and symptoms of an overdose. Which of the following should the healthcare provider give to reverse digoxin toxicity?

• A. Naloxone
• B. Vitamin K
• C. Digibind
• D. Flumazenil

Correct answer: C

Rationale: Digibind, also known as Digoxin immune Fab, is the specific antidote used to treat digoxin toxicity. It works by binding to digoxin in the body, forming a complex that can be excreted by the kidneys, thereby reversing the toxic effects of digoxin overdose. Naloxone is used for opioid overdoses, not digoxin toxicity. Vitamin K is used to reverse the effects of warfarin overdose. Flumazenil is used to reverse the effects of benzodiazepine overdose, not digoxin toxicity.

3. A client has a prescription for Timolol eye drops for the treatment of glaucoma. Which of the following instructions should the nurse include?

• A. Apply gentle pressure to the nasolacrimal duct for 30 to 60 seconds after application.
• B. Avoid blinking immediately after instilling the drops.
• C. Keep your eyes closed for 5 minutes after application.
• D. Administer the drops directly onto the cornea.

Correct answer: A

Rationale: The correct instruction for the nurse to include is to apply gentle pressure to the nasolacrimal duct for 30 to 60 seconds after application. This technique helps prevent systemic absorption of the medication, reducing the risk of systemic side effects. By applying pressure, the drainage of the medication into the bloodstream through the nasolacrimal duct is minimized, enhancing the drug's local ocular effects. Choices B, C, and D are incorrect because blinking immediately after instilling the drops, keeping eyes closed for 5 minutes, and administering the drops directly onto the cornea are not recommended practices for administering Timolol eye drops.

4. A client has a new prescription for Digoxin for heart failure. Which of the following adverse effects should the client be instructed to monitor for and report to the provider?

• A. Dry cough
• B. Pedal edema
• C. Bruising
• D. Yellow-tinged vision

Correct answer: D

Rationale: Yellow-tinged vision is a potential adverse effect of digoxin, which may indicate toxicity. It is crucial for the client to report this symptom promptly to the healthcare provider to prevent any further complications. Dry cough is not typically associated with digoxin use. Pedal edema is a common symptom of heart failure, which digoxin is prescribed to manage. Bruising is not a common adverse effect of digoxin.

5. While caring for a client receiving IV heparin, which of the following findings should the nurse identify as an adverse effect of this medication?

• A. Hypertension
• B. Hyperglycemia
• C. Thrombocytopenia
• D. Leukopenia

Correct answer: C

Rationale: Thrombocytopenia, a decrease in platelet count, is a known adverse effect associated with heparin therapy. It can lead to an increased risk of bleeding and should be closely monitored during treatment. Choices A, B, and D are incorrect. Hypertension is not typically associated with heparin use; hyperglycemia is not a common adverse effect of heparin; leukopenia is not a primary side effect of heparin therapy.
