Question 1 of 5
Which of the following antihypertensives act on the vasomotor centre:
Correct Answer: B
Rationale: Prazosin, an alpha-1 blocker, acts peripherally, not on the vasomotor center. Methyldopa, a centrally acting α2 agonist, reduces sympathetic outflow from the vasomotor center, a true statement lowering blood pressure. Hydralazine dilates arteries directly, not centrally. Reserpine depletes catecholamines peripherally and centrally but isn't primarily vasomotor-focused. Losartan (likely misspelled) is an ARB, peripheral. Methyldopa's central action is key in pregnancy hypertension, offering a unique mechanism among antihypertensives.
Question 2 of 5
Which finding would most accurately indicate that a therapeutic range for a medication had been reached?
Correct Answer: B
Rationale: Therapeutic range balances efficacy-treating the condition (indication)-with safety, avoiding serious side effects, a clinical goal. No adverse effects alone doesn't confirm efficacy. Dose amount doesn't ensure range. Effectiveness with lethal effects exceeds range. Achieving indication safely defines therapeutic success, per pharmacology.
Question 3 of 5
The patient is receiving zolpidem (Ambien) for treatment of short-term insomnia. What is the primary safety concern of the nurse when the patient takes this medication?

Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
A 78-year-old woman with ovarian cancer and pancreatitis is hospitalized for acute treatment of a massive pulmonary embolism. She is immediately given an intravenous dose of alteplase once the diagnosis of pulmonary embolism was made. Characteristics of this agent include which of the following?
Correct Answer: D
Rationale: Alteplase treats pulmonary embolism by dissolving clots. Success at clot resolution is correct-it converts plasminogen to plasmin, breaking fibrin. Option , free plasminogen, is less specific than its fibrin-bound action. Option , high antigenicity, and , low specificity, are false-alteplase is fibrin-specific and recombinant. Option (E), long half-life, isn't true. Its efficacy in clot lysis is key in this acute setting.
