The nurse caring for a client with thyroid disease notes a current T4 level of 2.9 mcg/dL (normal range: 5-11.5 mcg/dL). Which findings are consistent with this result?
Tachycardia and weight gain
Diarrhea and hypoglycemia
Hypotension and periorbital edema
Tremors and dyskinesias
The Correct Answer is C
Choice A reason: Tachycardia and weight gain are not typically associated with low T4 levels. Tachycardia and weight loss are more commonly seen in hyperthyroidism, where T4 levels would be elevated.
Choice B reason: Diarrhea and hypoglycemia are not directly related to low T4 levels. Diarrhea can be a symptom of hyperthyroidism, while hypoglycemia is not commonly associated with thyroid function.
Choice C reason: Hypotension and periorbital edema are findings that can be associated with hypothyroidism, which is consistent with the low T4 level of 2.9 mcg/dL. Hypothyroidism can lead to reduced cardiac output and systemic vascular resistance, causing hypotension. Periorbital edema is also a common sign of hypothyroidism due to mucopolysaccharide deposition in the skin.
Choice D reason: Tremors and dyskinesias are more commonly associated with hyperthyroidism, not hypothyroidism. Elevated levels of thyroid hormones can lead to these neurological symptoms.

Correct Answer is ["A","C","D"]
Explanation
Choice A reason: Monitoring platelet count is important in sepsis as thrombocytopenia can occur due to disseminated intravascular coagulation (DIC).
Choice B reason: Urine specific gravity is not typically monitored for sepsis unless there is a concern for renal function or fluid balance.
Choice C reason: Lactate levels are monitored in sepsis to assess the severity of septic shock and tissue hypoperfusion.
Choice D reason: PaO2 is monitored to assess oxygenation status, which can be compromised in sepsis due to respiratory dysfunction.
Choice E reason: Serum ammonia is not typically monitored for sepsis unless there is a concern for hepatic function or encephalopathy.
Correct Answer is B
Explanation
Choice A reason: Tachycardia, or rapid heart rate, is typically a symptom of an overdose of levothyroxine, not an underdose.
Choice B reason: Intolerance to cold is a common symptom of hypothyroidism, which occurs when the thyroid hormone levels are too low, indicating that the levothyroxine dose may be insufficient.
Choice C reason: Weight loss is more commonly associated with hyperthyroidism or an excessive dose of levothyroxine.
Choice D reason: Fine tremors of fingers and hands are also more indicative of hyperthyroidism or too high a dose of levothyroxine.
