Question 1 of 5
Most β blockers:
Correct Answer: A
Rationale: Most beta-blockers (e.g., propranolol, metoprolol) have half-lives of 3-10 hours, a true statement reflecting their typical duration, useful for dosing frequency. They have a large, not small, volume of distribution due to tissue penetration, so that's false. Many have good oral bioavailability, not poor, especially non-selective ones. Lipid solubility varies (e.g., propranolol is high, atenolol low), but many cross the BBB, causing CNS effects, though not universally true. They're often metabolized, not excreted unchanged. The half-life range is a key pharmacokinetic feature, guiding their use in hypertension or angina.
Question 2 of 5
Which of the following are the four categories of pharmacokinetics?
Correct Answer: C
Rationale: Pharmacokinetics comprises absorption (entry to blood), distribution (to tissues), metabolism (chemical change), and excretion (removal)-standard categories tracking a drug's journey. Others mix processes or invent terms (e.g., interspersing), lacking precision. These four define the field, essential for dosing and effect.
Question 3 of 5
The patient has generalized anxiety disorder. He asks the nurse, 'Will I need medication for this? My neighbor is very nervous and he takes medication.' What is the best response by the nurse?
Correct Answer: D
Rationale: Medication for GAD (e.g., SSRIs) is warranted when anxiety disrupts daily function-quality of life-not universally or compared to others, a tailored approach. Meds as lifestyle is extreme. Initial meds then therapy assumes progression, not individual need. ‘Probably not' dismisses severity. Quality of life guides treatment, per guidelines.
Question 4 of 5
The client has arthritis and has just learned that she is pregnant. What is the best instruction by the nurse?
Correct Answer: C
Rationale: Pregnancy limits arthritis options-splinting supports joints safely, per non-drug care. Heat helps, not avoided. Hydroxychloroquine needs caution (Category C). Glucocorticoids (D) risk cleft palate-unsafe. Splinting fits pregnancy, per safety.
Question 5 of 5
A 3-year-old girl was found by her mother chewing on some weeds in their flower garden. The mother rushed her to the hospital along with a portion of the weed. The emergency department physician identifies the weed as deadly nightshade, which contains atropine. Which of the following physiologic changes will be expected because of this patient's atropine exposure?
Correct Answer: B
Rationale: Deadly nightshade (atropine) blocks muscarinic receptors. Decreased gastric acid secretion is correct-atropine inhibits parasympathetic stimulation of parietal cells. Bradycardia is wrong; tachycardia occurs. Increased bronchial secretions and salivation decrease, as does miosis (E)-pupils dilate. This anticholinergic effect explains the expected change in this poisoning.
