A nurse is teaching about levothyroxine with a client who has primary hypothyroidism. Which of the following statements should the nurse use when teaching the client?

Symptoms improve immediately after starting the medication

The medication decreases the overproduction of the thyroid hormone thyroxine

Take this medication until your symptoms are gone and then discontinue

Tremors, nervousness, and insomnia may indicate your dose is too high

Answer and Explanation

The Correct Answer is D

Choice A reason: Levothyroxine takes weeks to normalize metabolism in hypothyroidism as T4 converts to T3 gradually, so immediate symptom relief isn’t accurate or expected.

Choice B reason: Levothyroxine supplements, not decreases, thyroxine in hypothyroidism. Decreasing overproduction applies to hyperthyroidism treatments like antithyroid drugs, not this condition.

Choice C reason: Hypothyroidism requires lifelong levothyroxine since the thyroid can’t produce hormone. Stopping when symptoms resolve risks recurrence, making this advice incorrect.

Choice D reason: Excess levothyroxine mimics hyperthyroidism, causing tremors, nervousness, and insomnia from overstimulated metabolism, correctly indicating a need for dose adjustment.

Correct Answer is A

Explanation

Choice A reason: Albuterol, a bronchodilator, rapidly opens airways in COPD, relieving acute shortness of breath and improving oxygenation from 85% by relaxing bronchial smooth muscle.

Choice B reason: Mucolytics thin mucus over time, not addressing acute dyspnea or low saturation (85%) quickly, lacking the immediacy needed in this scenario.

Choice C reason: Montelukast prevents asthma inflammation long-term via leukotriene blockade, not providing rapid relief for COPD’s acute bronchospasm or hypoxia here.

Choice D reason: Prednisone reduces COPD inflammation systemically, but its slow onset doesn’t acutely reverse shortness of breath or oxygen drop like a bronchodilator.

A. Hypervolemia B. Hypovolemia C. Hyperkalemia D. Hyponatremia

Correct Answer is A

Explanation

Choice A reason: ESRD impairs fluid excretion, causing hypervolemia, leading to edema, crackles from pulmonary fluid, and hypertension from increased vascular volume, matching these symptoms.

Choice B reason: Hypovolemia, low fluid volume, causes hypotension and dry tissues, not swelling, crackles, or high blood pressure, which indicate excess fluid, not deficit.

Choice C reason: Hyperkalemia elevates potassium, causing arrhythmias or muscle issues, not directly linked to crackles, edema, or hypertension, which are fluid-related in ESRD.

Choice D reason: Hyponatremia, low sodium, may cause neurological symptoms, but crackles, edema, and hypertension point to fluid overload, not sodium imbalance primarily.
