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 B
Explanation
Choice A reason: 1 tablet (50 mcg) provides half the 100 mcg dose, insufficient for hypothyroidism treatment, underdosing the required thyroid hormone replacement level.
Choice B reason: 2 tablets (50 mcg each) equal 100 mcg, matching the prescribed dose, ensuring adequate T4 replacement for hypothyroidism’s metabolic needs daily.
Choice C reason: 3 tablets (150 mcg) exceed the 100 mcg dose, risking hyperthyroidism symptoms like tachycardia or nervousness from excessive thyroid hormone administration.
Choice D reason: 4 tablets (200 mcg) grossly overdose the 100 mcg requirement, potentially causing severe thyrotoxicosis, disrupting metabolism and cardiac function dangerously.
Correct Answer is A
Explanation
Choice A reason: Weighing assesses fluid status pre-dialysis, guiding ultrafiltration goals in peritoneal dialysis to remove excess fluid safely, the priority for efficacy and safety.
Choice B reason: High Fowler’s aids breathing but isn’t critical pre-dialysis; semi-Fowler’s is used during, not before, making this secondary to weight assessment.
Choice C reason: Pain medication eases discomfort during dialysis but isn’t the priority; weight determines fluid removal needs first, ensuring treatment accuracy.
Choice D reason: Trendelenburg position aids hypotension, not routine pre-dialysis preparation, irrelevant to starting peritoneal dialysis compared to weight’s foundational role.
