Nursing Elites

1. When taking Digoxin, low levels of what can cause toxicity?

• A. Potassium
• B. Calcium
• C. Sodium
• D. Magnesium

Correct answer: A

Rationale: Low potassium levels can lead to Digoxin toxicity. Digoxin competes with potassium for binding sites on the sodium-potassium pump. When potassium levels are low, there is an increased risk of Digoxin binding and toxicity. Choice B (Calcium) is incorrect because low calcium levels are not directly linked to Digoxin toxicity. Choice C (Sodium) is incorrect as low sodium levels do not cause Digoxin toxicity. Choice D (Magnesium) is incorrect as low magnesium levels do not contribute to Digoxin toxicity.

2. A client is receiving moderate sedation with Diazepam IV and is oversedated. Which of the following medications should the nurse anticipate administering to this client?

• A. Ketamine
• B. Naltrexone
• C. Flumazenil
• D. Fluvoxamine

Correct answer: C

Rationale: Flumazenil is a specific benzodiazepine antagonist that competitively reverses the sedative effects of benzodiazepines like Diazepam. In cases of oversedation or respiratory depression caused by benzodiazepines, administering Flumazenil can help reverse the effects and restore the client's consciousness and respiratory drive. Ketamine (Choice A) is a dissociative anesthetic and not used to reverse benzodiazepine sedation. Naltrexone (Choice B) is an opioid receptor antagonist and not indicated for benzodiazepine oversedation. Fluvoxamine (Choice D) is an antidepressant and not used to counteract benzodiazepine sedation.

3. A client has a new prescription for Iron supplements. Which of the following instructions should be included?

• A. Take the medication with a glass of milk.
• B. Avoid taking the medication with orange juice.
• C. Increase fiber intake to prevent constipation.
• D. Expect stools to be bright red.

Correct answer: C

Rationale: The correct answer is C: 'Increase fiber intake to prevent constipation.' Iron supplements commonly cause constipation as a side effect. Increasing fiber intake can help alleviate this issue by promoting regular bowel movements and preventing constipation. Choice A is incorrect as iron absorption is hindered when taken with milk. Choice B is not directly related to iron supplements. Choice D is incorrect as iron supplements do not typically cause bright red stools.

4. A nurse is assessing a client who is receiving IV vancomycin. The nurse notes a flushing of the neck and tachycardia. Which of the following actions should the nurse take?

• A. Document that the client experienced an anaphylactic reaction to the medication.
• B. Change the IV infusion site.
• C. Decrease the infusion rate on the IV.
• D. Apply cold compresses to the neck area.

Correct answer: C

Rationale: Flushing and tachycardia are signs of Red Man Syndrome, which can be mitigated by decreasing the infusion rate.

5. Which of the following is classified as a class IA Sodium Channel blocker?

• A. Quinidine
• B. Disopyramide
• C. Aminodarone
• D. Propafenone

Correct answer: A

Rationale: Quinidine is classified as a class IA sodium channel blocker. Class IA antiarrhythmics, like quinidine, work by blocking sodium channels and delaying repolarization. Propafenone, mentioned in the original rationale, is actually a class IC antiarrhythmic agent, not a class IA sodium channel blocker.
