Question 1 of 5
A nurse is caring for a client who is taking montelukast. Which of the following outcomes indicates a therapeutic effect of the medication?
Correct Answer: C
Rationale: Montelukast, a leukotriene receptor antagonist, reduces airway inflammation in asthma and allergic rhinitis, leading to easier breathing. It does not affect seizure threshold, muscle pain, or platelet count.
Question 2 of 5
Acetylcysteine (Mucomyst) is a mucolytic that can also be used in the treatment of overdosage of which drug?
Correct Answer: C
Rationale: Acetylcysteine replenishes glutathione, neutralizing toxic acetaminophen metabolites in overdose, preventing liver damage. It's not used for overdoses of ibuprofen, diphenhydramine, or amoxicillin.
Question 3 of 5
A patient is in an urgent care center with an acute asthma attack. The nurse expects which medication will be used for initial treatment.
Correct Answer: B
Rationale: Albuterol, a short-acting beta-2 agonist, rapidly relaxes airway muscles, making it the first-line treatment for acute asthma attacks. Long-acting beta agonists, corticosteroids, and anticholinergics are not used for immediate relief.
Question 4 of 5
A nurse is caring for a client who is prescribed diphenhydramine to relieve pruritus. The client asks the nurse how he can minimize the daytime sedation he is experiencing. Which of the following responses should the nurse give?
Correct Answer: D
Rationale: Taking diphenhydramine at bedtime minimizes daytime sedation, as its sedative effects occur during sleep. Other options do not effectively reduce daytime drowsiness.
Question 5 of 5
A nurse is preparing to administer a medication to a client who states, 'That looks different from the pill I usually take.' Which of the following responses should the nurse make?
Correct Answer: D
Rationale: Asking the client to describe the pill allows the nurse to verify the medication, ensuring safety and addressing potential errors. Other responses dismiss the concern or provide unverified assumptions.
