Question 1 of 5
A nurse is preparing to administer erythromycin PO to a client who has an infection. The nurse checks the client's medical record and notes that the client has a severe allergy to penicillin. Which of the following actions should the nurse take?
Correct Answer: B
Rationale: The correct answer is B: Administer the medication to the client. Erythromycin is not a penicillin-based antibiotic, so having a severe allergy to penicillin does not contraindicate the use of erythromycin.
Therefore, it is safe to administer erythromycin to the client. Requesting a different medication (
Choice
A) is unnecessary as erythromycin is a suitable choice. Premedicating with diphenhydramine (
Choice
C) is not indicated unless the client has a known allergy to erythromycin. Requesting a different route of administration (
Choice
D) is unnecessary if the oral route is appropriate.
Question 2 of 5
A nurse is caring for a client who is receiving treatment for chronic alcohol use disorder. Which of the following medications should the nurse plan to administer to assist the client in maintaining abstinence by aversion therapy?
Correct Answer: B
Rationale: The correct answer is B: Disulfiram. Disulfiram is used in aversion therapy for alcohol use disorder by causing unpleasant effects like nausea, vomiting, and flushing if alcohol is consumed. This helps the client associate alcohol intake with negative consequences, promoting abstinence. Carbamazepine (
A) is used for seizures and mood disorders, not for aversion therapy. Atenolol (
C) is a beta-blocker used for hypertension, not for aversion therapy. Lorazepam (
D) is a benzodiazepine used for anxiety, not for aversion therapy.
Question 3 of 5
A nurse is planning to administer medications to a client who has trigeminal neuralgia. Which of the following medications should the nurse plan to administer to manage the client's pain?
Correct Answer: C
Rationale: The correct answer is C: Carbamazepine. Carbamazepine is commonly used to manage trigeminal neuralgia pain as it works by reducing the abnormal electrical activity in the brain that causes the pain. Lorazepam (
A) is a benzodiazepine used for anxiety and not specifically for trigeminal neuralgia. Fluoxetine (
B) is an antidepressant and not indicated for trigeminal neuralgia pain. Methylphenidate (
D) is a stimulant used for ADHD and narcolepsy, not for trigeminal neuralgia pain.
Question 4 of 5
A nurse in a mental health facility is collecting data from a client who is taking lithium. Which of the following findings should the nurse report to the provider as an indication of lithium toxicity?
Correct Answer: A
Rationale: The correct answer is A: Slurred speech. Lithium toxicity can manifest as neurologic symptoms, including slurred speech. This is crucial to report promptly to the provider as it indicates a potential overdose. Stooped posture (
B) is not a typical sign of lithium toxicity. Elevated blood pressure (
C) and dry cough (
D) are not specific to lithium toxicity.
Question 5 of 5
A nurse is caring for a client who has a new prescription for a nitroglycerin transdermal patch. Which of the following actions should the nurse take?
Correct Answer: C
Rationale: The correct answer is C: Rotate the application sites of the patch. This is important to prevent skin irritation and tolerance to the medication. By rotating sites, the nurse ensures proper absorption and effectiveness of the medication.
Choice A is incorrect because the patch should not be removed prior to bathing as it may disrupt the medication delivery.
Choice B is incorrect as nitroglycerin is used to treat hypotension, not hypertension.
Choice D is incorrect because nitroglycerin patches are typically left on for 12-14 hours, not removed every 24 hours.
