Complete the following sentence: Given the patient’s symptoms of dyspnea and fatigue, the nurse anticipates the primary care provider may increase the dose of (medication class) to help reduce fluid overload.
Beta blockers
Diuretics
Ace Inhibitors
The Correct Answer is B
Choice A reason: Beta blockers like metoprolol reduce heart rate and demand, improving heart failure long-term. They don’t directly reduce fluid overload causing dyspnea and fatigue, focusing instead on cardiac remodeling, not acute volume relief.
Choice B reason: Diuretics like furosemide increase urine output, reducing fluid overload in heart failure. They directly relieve dyspnea and fatigue by lowering preload and pulmonary congestion, the most effective class for these symptoms.
Choice C reason: ACE inhibitors like lisinopril ease vascular resistance, aiding heart failure. They reduce fluid indirectly via aldosterone suppression, but diuretics act faster on acute overload, making them secondary for immediate symptom relief.

Correct Answer is C
Explanation
Choice A reason: Assessing pain requires subjective interpretation and clinical judgment to gauge severity and response. This nursing task can’t be delegated, as assistants lack training to evaluate pain’s impact on respiratory status or intervention needs.
Choice B reason: Checking the water-seal chamber involves understanding pneumothorax mechanics and system integrity. This technical skill exceeds an assistant’s scope, requiring a nurse to ensure proper function and detect complications like air leaks.
Choice C reason: Documenting drainage volume is a routine task after RN measurement, involving recording observed data. It fits an assistant’s role, as it requires no analysis or intervention, making it a safe delegation for tracking output.
Choice D reason: Obtaining drainage samples involves sterile technique and system manipulation, risking infection or disruption. This skilled procedure remains a nursing duty, as assistants aren’t trained to handle invasive equipment safely.
Correct Answer is A
Explanation
Choice A reason: Hospitalized patients often have immobility, surgery, or illness, increasing VTE risk via stasis, vessel injury, and hypercoagulability (Virchow’s triad). Studies show up to 60% of VTE cases occur in this setting, confirming the statement.
Choice B reason: False implies low VTE risk in hospitals, contradicting evidence. Inactivity and acute conditions elevate risk significantly, with prophylaxis standard in guidelines, as immobility alone triples clot formation likelihood.
