Which of the following symptoms is indicative of right-sided heart failure?
Crackles
Orthopnea
Jugular venous distention
Blood-tinged sputum
The Correct Answer is C
Choice A reason: Crackles indicate pulmonary edema from left-sided heart failure, where fluid backs up into lungs, not right-sided failure, which affects systemic circulation instead.
Choice B reason: Orthopnea, dyspnea when lying flat, results from left-sided failure’s pulmonary congestion, not right-sided failure, which causes systemic venous pooling, not lung issues.
Choice C reason: Jugular venous distention occurs in right-sided heart failure as the right ventricle fails, backing blood into veins, elevating neck vein pressure visibly.
Choice D reason: Blood-tinged sputum suggests pulmonary edema or infarction, tied to left-sided failure or embolism, not right-sided failure’s systemic congestion pattern.

Correct Answer is D
Explanation
Choice A reason: Increasing oxygen to 3 L/min may help but risks CO2 retention in COPD without assessing respiratory rate, depth, and saturation first, making it premature.
Choice B reason: Coughing clears secretions, but without assessing respiratory status, it’s unclear if secretions are the issue or if the client can effectively cough, so it’s not priority.
Choice C reason: Calling emergency services assumes severity without data like oxygen saturation or distress level, delaying care by skipping initial assessment in this stable setting.
Choice D reason: Assessing respiratory status (rate, oxygen saturation, lung sounds) identifies the cause of difficulty, guiding interventions like oxygen adjustment or escalation, per ABC priority.
Correct Answer is A
Explanation
Choice A reason: Mucolytics (e.g., acetylcysteine) break disulfide bonds in mucus, thinning it to ease expectoration, directly aiding secretion clearance in respiratory conditions.
Choice B reason: Glucocorticoids reduce inflammation in airways, not liquefying mucus; they address swelling, not viscosity, so they don’t facilitate expulsion directly.
Choice C reason: Calcium channel blockers relax vascular smooth muscle for hypertension, not affecting mucus consistency or respiratory secretions, irrelevant to this goal.
Choice D reason: Bronchodilators open airways, improving airflow, but don’t alter mucus viscosity, aiding breathing, not secretion liquefaction or removal specifically.
