1. What is the therapeutic class of Valproate?
- A. Anticoagulant
- B. Antianxiety, benzodiazepines
- C. Anticonvulsant, vascular headache suppressant
- D. Mood stabilizer
Correct answer: C
Rationale: Valproate belongs to the therapeutic class of anticonvulsants. It is primarily used to manage seizures but is also effective in treating vascular headaches. Therefore, it is not classified as an anticoagulant, antianxiety medication, or mood stabilizer. Option A, anticoagulant, is incorrect as valproate does not have anticoagulant properties. Option B, antianxiety benzodiazepines, is incorrect as valproate is not primarily used to treat anxiety disorders with benzodiazepines. Option D, mood stabilizer, is incorrect as valproate is not classified as a mood stabilizer, although it can be used in some cases for mood disorders, its primary therapeutic class is anticonvulsant.
2. When educating a client with a new prescription for Enalapril, which manifestation should the nurse instruct the client to report as an adverse effect of this medication?
- A. Tremors
- B. Dry cough
- C. Drowsiness
- D. Hyperactivity
Correct answer: B
Rationale: A persistent dry cough is a well-known adverse effect of ACE inhibitors, such as enalapril. This cough can be bothersome and may indicate the need for a medication adjustment. It is crucial for the client to report this symptom to their healthcare provider to explore potential alternatives or adjustments to the treatment plan. Tremors, drowsiness, and hyperactivity are not commonly associated with enalapril and are less likely to be attributed to this medication.
3. A client has a new prescription for Methotrexate to treat Rheumatoid Arthritis. Which of the following instructions should the nurse provide?
- A. Take this medication with food to prevent nausea.
- B. Drink plenty of fluids to stay hydrated while on this medication.
- C. Avoid alcohol while taking this medication.
- D. Wear sunscreen when outdoors while taking this medication.
Correct answer: C
Rationale: The correct instruction for a client taking Methotrexate is to avoid alcohol, as it can increase the risk of liver damage. Alcohol consumption should be avoided to prevent potential adverse effects while on this medication.
4. A client in the post-anesthesia recovery unit received a nondepolarizing neuromuscular blocking agent and is experiencing muscle weakness. The nurse should anticipate a prescription for which of the following medications?
- A. Neostigmine
- B. Naloxone
- C. Dantrolene
- D. Vecuronium
Correct answer: A
Rationale: Neostigmine is a cholinesterase inhibitor commonly used to reverse the effects of nondepolarizing neuromuscular blockers by increasing acetylcholine levels at the neuromuscular junction, thereby helping to restore muscle strength. Naloxone is an opioid antagonist used to reverse opioid effects, not neuromuscular blockade. Dantrolene is a skeletal muscle relaxant used to treat malignant hyperthermia or neuroleptic malignant syndrome, not to reverse neuromuscular blockade. Vecuronium is a nondepolarizing neuromuscular blocking agent, like the one the client received, and is not used to reverse its effects.
5. A healthcare provider in a clinic is monitoring serum electrolytes for four older adult clients who take digoxin. Which of the following electrolyte values increases a client's risk for Digoxin toxicity?
- A. Calcium 9.2 mg/dL
- B. Calcium 10.3 mg/dL
- C. Potassium 3.4 mEq/L
- D. Potassium 4.8 mEq/L
Correct answer: C
Rationale: Potassium 3.4 mEq/L is below the expected reference range, which increases the risk for digoxin toxicity. Low potassium levels can lead to fatal dysrhythmias, particularly in older clients taking Digoxin. Hypokalemia potentiates the effects of Digoxin, making the heart more sensitive to its toxic effects. Monitoring and correcting electrolyte imbalances, especially low potassium levels, are crucial to prevent adverse effects of digoxin therapy. Calcium levels do not directly influence digoxin toxicity, so choices A and B are incorrect. High potassium levels, as in choice D, are less likely to increase the risk of digoxin toxicity compared to low potassium levels.
