Question 1 of 5
When administering the drug lithium, name one important side effect to watch for:
Correct Answer: B
Rationale: One important side effect to watch for when administering the drug lithium is seizures. Lithium is commonly used to treat bipolar disorder, but it can lower the seizure threshold and increase the risk of seizures in some patients. It is crucial to monitor individuals taking lithium for any signs of seizures or seizure activity and to promptly address any such occurrences. Regular monitoring of lithium levels and adjusting the dosage as necessary can help minimize the risk of seizures in patients receiving this medication.
Question 2 of 5
Which of the following is NOT an ester type of local anesthetics:
Correct Answer: D
Rationale: Cocaine is not an ester type of local anesthetic. While procaine, amethocaine, benzocaine, and etidocaine are all ester type local anesthetics, cocaine belongs to the group of local anesthetics known as ester anesthetics. Even though cocaine has local anesthetic properties, it is specifically classified as a "amide type" local anesthetic, not an ester type. Therefore, the correct choice among the given options is D. Cocaine.
Question 3 of 5
It is a measure of drug activity in terms of the amount required to produce an effect.
Correct Answer: C
Rationale: Potency refers to the measure of drug activity in terms of the amount required to produce a particular effect. It is the strength or concentration of a drug that is needed to produce a specific effect. Potency is often expressed as the dose of a drug required to produce a certain response compared to a standard reference dose. It is an essential consideration in pharmacology as it helps determine the appropriate dosage needed for therapeutic effects and to avoid potential toxicity. Potency is distinct from efficacy, which is the ability of a drug to produce a desired effect regardless of the dose.
Question 4 of 5
A patient who has been diagnosed with social anxiety disorder will begin taking venlafaxine(Effexor). The nurse who performs a medication and dietary history will be concerned about ingestion of which substance or drug?
Correct Answer: D
Rationale: St. John's wort is an herbal supplement known to interact with many medications, including venlafaxine (Effexor). It can reduce the effectiveness of venlafaxine by increasing its metabolism and clearance from the body, potentially leading to decreased therapeutic effects. Therefore, patients taking venlafaxine for social anxiety disorder should be advised to avoid St. John's wort to prevent any negative interactions and ensure the medication works effectively. It is essential for the nurse to inquire about the use of St. John's wort during the medication and dietary history assessment to prevent such interactions.
Question 5 of 5
The nurse is caring for a patient who is receiving an adrenergic blocking agent. While writing the care plan for this patient what nursing diagnoses would be most appropriate concerning comfort?
Correct Answer: A
Rationale: All four options would be appropriate nursing diagnoses for a patient receiving an adrenergic blocking agent. However, acute pain would be the only nursing diagnosis related to the patient’s comfort level. The nurse should address pain management as a priority to improve the patient’s quality of life and adherence to treatment.
