Extract:
Question 1 of 5
A nurse is providing discharge teaching to a client who has asthma and new prescriptions for beclomethasone and albuterol, both by inhaler. Which of the following statements by the client indicates an understanding of the teaching?
Correct Answer: A
Rationale: Albuterol, a bronchodilator, should be used before beclomethasone, a corticosteroid, to open airways and enhance corticosteroid delivery. Beclomethasone is not for acute symptoms, and timing is less critical than sequence.
Question 2 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 3 of 5
The Parasympathetic Nervous System utilizes which neurotransmitter?
Correct Answer: B
Rationale: The parasympathetic nervous system uses acetylcholine in both preganglionic and postganglionic neurons to regulate rest-and-digest functions. Other options are incorrect neurotransmitters for this system.
Question 4 of 5
A nurse is providing discharge teaching to the parent of a child who is prescribed diphenhydramine 25 mg elixir every 4 hr as needed. The amount available is diphenhydramine elixir 12.5 mg/5 mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
Correct Answer: A
Rationale: Calculation: 25 mg / (12.5 mg/5 mL) = 25 * 5 / 12.5 = 10 mL. The nurse should administer 10 mL per dose.
Question 5 of 5
A nurse is evaluating teaching a client who has a new prescription for montelukast to treat asthma. Which of the following statements by the client indicates an understanding of the teaching?
Correct Answer: D
Rationale: Montelukast is taken once daily, typically in the evening, for asthma maintenance. It's oral, not inhaled, and not for acute attacks, so rinsing or using a spacer is unnecessary.
