Nursing Elites

1. What is the therapeutic use of Phenytoin?

• A. Replacement in hypothyroidism to restore normal hormonal balance
• B. Diminished accumulation of acid in the gastric lumen with lessened gastroesophageal reflux
• C. Diminished seizure activity, termination of ventricular arrhythmias
• D. Prevention of thrombus formation, prevention of extension of existing thrombi

Correct answer: C

Rationale: Phenytoin is primarily used to diminish seizure activity and is effective in terminating ventricular arrhythmias. It works by stabilizing neuronal membranes, reducing repetitive neuronal firing, and limiting the spread of seizure activity in the brain. While phenytoin does not have a direct role in preventing thrombus formation or extending existing thrombi, it is crucial in managing seizures and certain arrhythmias.

2. A client is receiving warfarin therapy. Which of the following findings should the nurse identify as an adverse effect of warfarin?

• A. Nausea
• B. Epistaxis
• C. Diarrhea
• D. Dyspepsia

Correct answer: B

Rationale: Epistaxis, or nosebleeds, can be an indication of excessive anticoagulation while on warfarin therapy. Warfarin is a blood thinner that helps prevent blood clots. Epistaxis can occur as a result of the blood-thinning effects of warfarin, leading to increased bleeding tendencies, including nosebleeds. Nausea, diarrhea, and dyspepsia are not typically associated with warfarin therapy; therefore, they are not the adverse effects the nurse should identify in a client receiving warfarin.

3. 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.

4. A client has a new prescription for Metformin. Which of the following adverse effects of Metformin should the nurse instruct the client to report to the provider?

• A. Somnolence
• B. Constipation
• C. Fluid retention
• D. Weight gain

Correct answer: A

Rationale: The correct answer is A: Somnolence. Somnolence can indicate lactic acidosis, a rare but serious adverse effect of Metformin. Lactic acidosis is manifested by extreme drowsiness, hyperventilation, and muscle pain. Clients should be instructed to report these symptoms to their healthcare provider promptly to prevent further complications.

5. When teaching a client with a prescription for Vancomycin, which instruction should the nurse include?

• A. Expect red man syndrome during treatment.
• B. Take the medication with a full glass of water.
• C. Increase your intake of potassium-rich foods.
• D. Monitor for hearing loss while taking this medication.

Correct answer: D

Rationale: The correct answer is D. Vancomycin is known to cause ototoxicity, which can result in hearing loss. Therefore, it is important for clients to monitor for any changes in their hearing while taking this medication and promptly report any issues to their healthcare provider for further evaluation and management. Choices A, B, and C are incorrect because red man syndrome is associated with rapid infusion of Vancomycin, not a common side effect during treatment; taking the medication with a full glass of water is a general instruction for many medications but not specific to Vancomycin; and increasing potassium-rich foods is not directly related to Vancomycin therapy.
