The client receives albuterol (Proventil) via inhaler. He asks the nurse why he can't just take a pill. What is the best response by the nurse?

Correct Answer: A

Rationale: Albuterol's inhalation targets lungs directly, with rapid absorption for quick relief (minutes vs. hours for oral). Pills work but slower. Side effects differ, not the reason. Efficacy varies by route. A explains pharmacokinetics, making it the best response.

Correct Answer: B

Rationale: The high alert nursing implication for Morphine is to assess the level of consciousness, blood pressure, pulse, and respiration. Morphine is a potent opioid analgesic that can cause respiratory depression, sedation, and hypotension as side effects. Monitoring the patient's vital signs and neurological status is crucial to detect any signs of overdose or adverse reactions promptly. Maintaining vigilant observation of these parameters can help prevent serious complications and ensure the safe administration of Morphine.

Correct Answer: A

Rationale: The nurse should include the instruction to avoid drinking large amounts of green tea when providing dietary teaching for a patient receiving warfarin therapy. Green tea is high in vitamin K, which can interfere with the effectiveness of warfarin, an anticoagulant medication. Maintaining a consistent intake of vitamin K is important for patients on warfarin in order to keep their INR (International Normalized Ratio) levels stable. It is not necessary to avoid all sources of vitamin K, but rather to keep intake consistent and moderate. Drinking large amounts of green tea, which is high in vitamin K, can potentially impact the patient's INR levels and increase the risk of bleeding or clotting issues.

Correct Answer: C

Rationale: CNS stimulants (e.g., methylphenidate) boost focus in ADHD via dopamine/norepinephrine-per standard-unlike depressants (sedate), parasympathomimetics (cholinergic), or sympathomimetics (broader). Stimulants are traditional, per treatment.

Correct Answer: D

Rationale: Atypical antipsychotics are linked to stroke in elderly patients with dementia. They are effective against negative symptoms and do not bind irreversibly to D2 receptors.
