The nurse is assessing a client with a history of heart failure who reports new-onset dyspnea and fatigue. Which finding requires the most immediate intervention?

Crackles in bilateral lower lobes.

Heart rate of 92 beats/minute.

Blood pressure of 138/86 mm Hg.

Peripheral edema 1+ in ankles.

Answer and Explanation

The Correct Answer is A

Choice A reason: Crackles in bilateral lower lobes indicate pulmonary edema in heart failure, where reduced cardiac output causes fluid backup into alveoli, impairing gas exchange and causing dyspnea. This life-threatening emergency requires immediate diuretics or oxygen to reduce preload, preventing respiratory failure or hypoxia, prioritizing intervention.

Choice B reason: A heart rate of 92 beats/minute is normal and not urgent in heart failure, where dyspnea and fatigue suggest fluid overload. Crackles indicate pulmonary edema, a critical issue compromising oxygenation, necessitating immediate action to restore respiratory function, making heart rate less concerning.

Choice C reason: Blood pressure of 138/86 mm Hg is mildly elevated but not critical in heart failure. Crackles signal pulmonary edema, where fluid in alveoli impairs gas exchange, risking hypoxia. This requires urgent intervention like furosemide, as respiratory compromise is more immediate than managing stable blood pressure.

Choice D reason: Peripheral edema 1+ indicates fluid retention in heart failure but is less urgent than crackles, which signify pulmonary edema. Alveolar fluid causes dyspnea and hypoxia, requiring immediate diuretics. Edema is chronic, making respiratory assessment and intervention the priority to prevent acute respiratory failure.

Correct Answer is A

Explanation

Choice A reason: Yellow purulent drainage indicates wound infection, likely from bacterial proliferation (e.g., Staphylococcus aureus) causing pus. This serious complication risks delayed healing, abscess, or sepsis, necessitating provider notification for cultures, antibiotics, or surgical intervention. Infection disrupts tissue repair, requiring urgent management to prevent systemic spread or wound dehiscence.

Choice B reason: Pink granulation tissue is normal in wound healing, reflecting angiogenesis and fibroblast activity during the proliferative phase. It indicates healthy tissue formation, not requiring notification. Purulent drainage, however, signals infection, a critical issue disrupting healing and risking complications, making it the priority finding for reporting.

Choice C reason: Serosanguineous fluid, a mix of serum and blood, is expected in early surgical wounds as capillaries heal. It does not indicate infection unless excessive. Purulent drainage is more urgent, directly suggesting bacterial infection, which can lead to serious complications like sepsis, requiring immediate provider attention.

Choice D reason: Approximated wound edges indicate proper closure and healing, reducing scarring and infection risk. This positive finding does not warrant notification. Yellow purulent drainage, conversely, signals infection, a critical complication requiring urgent intervention to prevent further tissue damage or systemic infection, making it the priority.

A. Palpitations and shortness of breath. B. Lethargy and lack of appetite. C. Muscle cramping and dry, flushed. D. Bradycardia and constipation.

Correct Answer is A

Explanation

Choice A reason: Excessive levothyroxine causes hyperthyroidism, increasing T3/T4, stimulating beta-adrenergic receptors, leading to palpitations (tachycardia) and shortness of breath from heightened cardiac workload and oxygen demand. These indicate overdose, risking atrial fibrillation, requiring immediate dose adjustment to prevent cardiovascular complications in this thyroid-treated client.

Choice B reason: Lethargy and lack of appetite suggest hypothyroidism, indicating low thyroid hormone levels from insufficient levothyroxine. These are opposite to overdose symptoms like palpitations, driven by excessive metabolism. High doses cause hyperthyroid effects, making this incorrect for identifying excessive dosing in goiter treatment.

Choice C reason: Muscle cramps and dry, flushed skin are not typical of levothyroxine overdose. Hyperthyroidism causes warm, moist skin from increased metabolism, not dryness. Cramps relate to electrolytes. Palpitations and shortness of breath are hallmark overdose signs, reflecting thyroid-driven cardiovascular overstimulation, making this less accurate.

Choice D reason: Bradycardia and constipation indicate hypothyroidism from low thyroid hormones, reducing heart rate and metabolism. This suggests inadequate levothyroxine, not overdose. Excessive doses cause hyperthyroidism, with palpitations and dyspnea from metabolic hyperactivity, making these symptoms incorrect for high-dose levothyroxine effects.
