1. A patient has been taking hydrocodone, an opioid analgesic for their moderate pain, and they have taken more than the prescribed dose. What should you administer as the antidote if they experience toxicity?
- A. Naloxone
- B. N-acetylcysteine
- C. Atropine
- D. Digoxin immune Fab
Correct answer: A
Rationale: Naloxone is the specific antidote for opioid toxicity. It works by blocking the effects of opioids on the central nervous system, thereby reversing symptoms like respiratory depression and sedation. N-acetylcysteine is used for acetaminophen overdose, while atropine is indicated for certain types of poisonings. Digoxin immune Fab is used for digoxin toxicity. Therefore, in the case of opioid toxicity due to hydrocodone overdose, naloxone is the appropriate antidote.
2. A client has been prescribed a calcium channel blocker for angina. The nurse knows this medication should NOT be used with caution in combination with which drug classes?
- A. NSAIDs
- B. Cardiac glycosides
- C. Beta blockers
- D. None of the above
Correct answer: C
Rationale: Calcium channel blockers and beta blockers should be used with caution together because they can both suppress heart function, potentially leading to bradycardia, heart block, or heart failure. NSAIDs and cardiac glycosides do not have significant interactions with calcium channel blockers in the same way, so they are not typically a cause for concern when combined.
3. A client has a new prescription for Atorvastatin. Which of the following instructions should be included?
- A. Take this medication with food.
- B. Avoid drinking grapefruit juice.
- C. Take this medication in the morning.
- D. Increase your intake of potassium-rich foods.
Correct answer: B
Rationale: The correct answer is to avoid drinking grapefruit juice when taking Atorvastatin. Grapefruit juice can interfere with the metabolism of Atorvastatin, leading to increased blood levels of the medication, which can result in a higher risk of adverse effects, such as muscle pain and liver damage. It is important for the client to follow this instruction to ensure the safe and effective use of Atorvastatin. Choices A, C, and D are incorrect. While taking Atorvastatin with food may be recommended for some individuals to reduce stomach upset, it is not a crucial instruction. The timing of Atorvastatin administration can vary depending on individual needs and is not universally fixed to the morning. Increasing potassium-rich foods is not directly related to Atorvastatin use and is not a standard precautionary measure associated with this medication.
4. A healthcare provider is providing discharge instructions to a client who has a new prescription for Warfarin. Which of the following over-the-counter medications should the provider instruct the client to avoid?
- A. Acetaminophen
- B. Ibuprofen
- C. Diphenhydramine
- D. Loratadine
Correct answer: B
Rationale: Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can increase the risk of bleeding when taken with Warfarin due to its antiplatelet effects. The combination of Warfarin, an anticoagulant, and NSAIDs can potentiate the risk of bleeding complications. Clients on Warfarin should avoid NSAIDs like ibuprofen and opt for alternative pain relief options such as acetaminophen. Diphenhydramine and loratadine are antihistamines and are generally safe to use with Warfarin as they do not significantly increase the risk of bleeding when compared to NSAIDs like ibuprofen.
5. A provider prescribes phenobarbital for a client who has a seizure disorder. The medication has a long half-life of 4 days. How many times per day should the nurse expect to administer this medication?
- A. One
- B. Two
- C. Three
- D. Four
Correct answer: A
Rationale: Phenobarbital, with a long half-life of 4 days, remains at therapeutic levels in the body for an extended period. Due to this prolonged duration of action, the nurse should administer phenobarbital once a day to maintain a consistent therapeutic effect without the need for multiple daily doses. Administering the medication more than once a day would not be necessary and could increase the risk of side effects or toxicity. Therefore, the correct answer is to administer phenobarbital once a day.
