client with COPD has an acute bronchospasm. The nurse knows the best medication for this emergency situation that is fast-acting is:

Dexamethasone (Decadron)

Zafirlukast (Accolate)

Oxtriphylline theophylline (Choledyl)

Epinephrine (Adrenalin)

Answer and Explanation

The Correct Answer is D

Choice A reason: Dexamethasone, a steroid, acts slowly, not fast for emergencies. Epinephrine relieves bronchospasm rapidly. This choice errors per nursing standards. It’s universally distinct as unsuitable for acute COPD bronchospasm relief.

Choice B reason: Zafirlukast prevents asthma, not acute bronchospasm; it’s slow-acting. Epinephrine works instantly. This choice misaligns with nursing pharmacology. It’s universally distinct, lacking emergency speed required.

Choice C reason: Oxtriphylline, a bronchodilator, is gradual, not fast-acting. Epinephrine suits emergencies better. This choice errors per nursing standards. It’s universally distinct, ineffective for acute bronchospasm relief.

Choice D reason: Epinephrine dilates bronchi fast, ideal for acute bronchospasm in COPD. It aligns with nursing pharmacology standards. This is universally applied, distinctly effective in emergency respiratory situations.

Correct Answer is B

Explanation

Choice A reason: Tear duct drains; it doesn’t hold ophthalmic meds. Conjunctival sac is correct. This errors per nursing standards. It’s universally distinct, wrong site.

Choice B reason: Conjunctival sac holds ophthalmic meds for absorption effectively. This fits nursing pharmacology standards. It’s universally applied, distinctly the right area.

Choice C reason: Sclera is eye surface, not a med site. Conjunctival sac is used. This misaligns with nursing pharmacology. It’s universally distinct, incorrect.

Choice D reason: Canthus, eye corner, isn’t for med administration. Conjunctival sac fits. This errors per nursing standards. It’s universally distinct, off-target.

A. Antihistamine B. Sedative C. Epinephrine D. Hormone

Correct Answer is C

Explanation

Choice A reason: Antihistamines block histamine, not raise HR or BP. Epinephrine fits emergency needs. This errors per nursing pharmacology. It’s universally distinct, lacking stimulatory emergency effects.

Choice B reason: Sedatives reduce activity, not increase HR or BP. Epinephrine acts oppositely. This choice reverses nursing standards. It’s universally distinct, unsuitable for emergency stimulation.

Choice C reason: Epinephrine boosts HR, BP, and dilates bronchi in emergencies. This matches nursing pharmacology standards. It’s universally applied, distinctly effective for acute life-saving interventions.

Choice D reason: Hormones vary; epinephrine specifically meets all criteria emergently. This lacks precision per nursing standards. It’s universally distinct, too vague for the question’s intent.
