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 being educated by a healthcare provider about a new prescription for Digoxin. Which of the following client statements indicates an understanding of the teaching?

• A. I will take the medication with a high-fiber meal.
• B. I should report any vision changes to my healthcare provider.
• C. I will take the medication if my heart rate is below 60 bpm.
• D. I should avoid dairy products while taking this medication.

Correct answer: B

Rationale: The correct answer is B. Visual disturbances, such as blurred vision or seeing halos, can be a sign of digoxin toxicity. It is crucial for the client to report any changes in vision to their healthcare provider promptly to prevent serious complications. Choice A is incorrect because taking Digoxin with a high-fiber meal can affect its absorption. Choice C is incorrect because taking Digoxin based on heart rate alone is not recommended without healthcare provider supervision. Choice D is incorrect because there is no specific interaction between Digoxin and dairy products.

3. A client has a new prescription for Warfarin. Which of the following instructions should the nurse include?

• A. Avoid consuming foods high in vitamin K.
• B. Monitor your blood pressure regularly.
• C. Increase your intake of green, leafy vegetables.
• D. Take the medication with a high-fat meal.

Correct answer: A

Rationale: The correct answer is to advise the client to avoid consuming foods high in vitamin K. Warfarin's effectiveness can be affected by vitamin K intake. Clients should maintain a consistent intake of vitamin K and avoid sudden increases in foods high in vitamin K to ensure the medication works properly and consistently. Choices B, C, and D are incorrect. Monitoring blood pressure, increasing intake of green, leafy vegetables, or taking the medication with a high-fat meal are not specific instructions related to Warfarin therapy.

4. A client has difficulty swallowing medications and is prescribed enteric-coated aspirin PO once daily. The client asks if the medication can be crushed to make it easier to swallow. Which of the following responses should the nurse provide?

• A. Crushing the medication might cause you to have a stomachache or indigestion.
• B. Crushing the medication is a good idea, and I can mix it in some ice cream for you.
• C. Crushing the medication would release all the medication at once, rather than over time.
• D. Crushing is unsafe, as it destroys the ingredients in the medication.

Correct answer: A

Rationale: Crushing an enteric-coated medication can cause it to break down in the stomach instead of the intestines, potentially leading to gastrointestinal distress like stomachache or indigestion. It is important to take enteric-coated medications whole to ensure they are properly absorbed in the intestines and to prevent irritation to the stomach.

5. A client in the operating room received a dose of Succinylcholine, leading to muscle rigidity and a sudden rise in body temperature. The nurse should anticipate a prescription for which of the following medications?

• A. Neostigmine
• B. Naloxone
• C. Dantrolene
• D. Vecuronium

Correct answer: C

Rationale: Muscle rigidity and a sudden rise in temperature are indicative of malignant hyperthermia, a potential complication of succinylcholine. Dantrolene is the drug of choice to treat malignant hyperthermia as it acts on skeletal muscles to reduce metabolic activity and counteract the symptoms. Neostigmine (Choice A) is used to reverse the effects of non-depolarizing neuromuscular blocking agents, not for malignant hyperthermia. Naloxone (Choice B) is an opioid antagonist used for opioid overdose. Vecuronium (Choice D) is a non-depolarizing neuromuscular blocking agent and is not the appropriate medication for malignant hyperthermia.
