Extract:
Question 1 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: D
Rationale: Lorazepam is a benzodiazepine used for alcohol withdrawal symptoms, not aversion therapy. Atenolol is a beta-blocker that may be used to manage some withdrawal symptoms but is not primarily for aversion therapy. Carbamazepine may be used to manage alcohol withdrawal symptoms, not aversion therapy. Disulfiram is used in aversion therapy to create a negative reaction when alcohol is consumed, helping clients maintain abstinence.
Question 2 of 5
A nurse is collecting data from a client who has hypertension. The nurse should recognize that which of the following over-the-counter medications is contraindicated for this client?
Correct Answer: C
Rationale: This medication is a stool softener and is not contraindicated for hypertension. This medication is an expectorant and is not contraindicated for hypertension. Pseudoephedrine is a decongestant that can increase blood pressure and is contraindicated for clients with hypertension. Omeprazole is a proton pump inhibitor used to reduce stomach acid and is not contraindicated for hypertension.
Question 3 of 5
A nurse is preparing to administer enoxaparin subcutaneously to a client using a prefilled syringe. The nurse should plan to use which of the following techniques when administering this medication?
Correct Answer: B
Rationale: The air bubble helps to ensure that the entire dose of medication is delivered and prevents bleeding from the injection site. The nurse should plan to inject enoxaparin subcutaneously into abdominal tissue using a prefilled syringe without expelling the air bubble or aspirating prior to injecting the medication. Aspiration is not recommended because it may cause hematoma formation. Massaging the site is generally not recommended after enoxaparin injections to avoid bruising or hematoma formation.
Question 4 of 5
A nurse is reviewing the medication history of a client who reports urinary retention. The nurse should recognize that which of the following medications can cause this adverse reaction?
Correct Answer: A
Rationale: Scopolamine is an anticholinergic medication that can cause urinary retention by blocking the parasympathetic stimulation of the bladder. Acetaminophen is not associated with urinary retention. Metoprolol is a beta-blocker and is not commonly associated with urinary retention. Donepezil has no effect on bladder function.
Question 5 of 5
A nurse is collecting data from a client who received diphenhydramine for insomnia. Which of the following findings should the nurse identify as an idiosyncratic reaction?
Correct Answer: D
Rationale: Dizziness is a common side effect of diphenhydramine but not considered idiosyncratic. Nausea is a common side effect and not considered idiosyncratic. Dry mouth is a common side effect and not considered idiosyncratic. An idiosyncratic reaction is an unexpected reaction to a drug that is not related to its known pharmacological effects. Agitation may be an unusual response to diphenhydramine.
