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 with end-stage cancer receiving Morphine has been prescribed Methylnaltrexone. The client's daughter asks about the purpose of Methylnaltrexone. Which response should the nurse provide?

• A. The medication will increase your mother's respirations.
• B. The medication will prevent dependence on the Morphine.
• C. The medication will relieve your mother's constipation.
• D. The medication works with the Morphine to increase pain relief.

Correct answer: C

Rationale: Methylnaltrexone is an opioid antagonist used to treat severe constipation unresponsive to laxatives in opioid-dependent clients. It functions by blocking the mu opioid receptors in the gastrointestinal tract, helping alleviate constipation associated with opioid use. Choices A, B, and D are incorrect. Methylnaltrexone does not increase respirations, prevent dependence on Morphine, or work with Morphine to increase pain relief; its primary purpose is to relieve opioid-induced constipation.

3. Which of the following drugs is associated with the reaction of Cinchonism?

• A. Valproic acid
• B. Quinidine
• C. Isoniazid
• D. Ethosuximide

Correct answer: B

Rationale: Cinchonism is associated with Quinidine, not Valproic acid, Isoniazid, or Ethosuximide. Cinchonism is characterized by symptoms such as tinnitus, dizziness, and headaches. Quinidine, being an antiarrhythmic agent, can lead to this condition as a side effect.

4. A healthcare professional in an emergency unit is reviewing the medical record of a client who is being evaluated for angle-closure glaucoma. Which of the following findings is indicative of this condition?

• A. Insidious onset of painless loss of vision
• B. Gradual reduction in peripheral vision
• C. Severe pain around the eyes
• D. Intraocular pressure 12 mm Hg

Correct answer: C

Rationale: Severe pain around the eyes that radiates over the face is a classic symptom of acute angle-closure glaucoma. This intense pain is often associated with other symptoms such as blurred vision, halos around lights, redness in the eye, and sometimes nausea and vomiting. Immediate medical attention is required to prevent permanent vision loss. Choices A, B, and D are incorrect. Insidious onset of painless loss of vision is more indicative of conditions like macular degeneration. Gradual reduction in peripheral vision is commonly seen in conditions like open-angle glaucoma. An intraocular pressure of 12 mm Hg is within the normal range and is not typical of angle-closure glaucoma.

5. A client has a new prescription for Oxycodone/Acetaminophen, and the nurse is providing discharge instructions. Which of the following instructions should the nurse include?

• A. Take the medication on an empty stomach.
• B. Avoid taking additional Acetaminophen while on this medication.
• C. Increase your intake of fiber while on this medication.
• D. Avoid taking the medication before bedtime.

Correct answer: B

Rationale: The correct instruction for a client with a prescription for Oxycodone/Acetaminophen is to avoid taking additional Acetaminophen while on this medication. Combining medications containing Acetaminophen can lead to exceeding the maximum recommended dose and increase the risk of liver toxicity. Therefore, it is crucial for the nurse to emphasize the importance of not taking extra Acetaminophen while on this prescription to ensure the client's safety and well-being. Choices A, C, and D are incorrect. Taking Oxycodone/Acetaminophen on an empty stomach is not necessary; increasing fiber intake is not directly related to this medication, and avoiding taking the medication before bedtime is not a specific concern associated with this prescription.
