Determine the flow rate in mL per hour for the following IV being administered by infusion pump: Ampicillin 1.5g in 100 mL 0.9% NS over 45 minutes: Round to the whole number.
The Correct Answer is ["133"]
Step 1: First, we need to determine how many mL per hour the IV is administering. We know that 100 mL is administered over 45 minutes.
Step 2: Convert 45 minutes to hours. 45 minutes ÷ 60 minutes = 0.75 hours
Step 3: Calculate the flow rate in mL per hour. 100 mL ÷ 0.75 hours
Step 4: Perform the division. 100 ÷ 0.75 = 133.33
Step 5: Round to the nearest whole number. 133.33 rounds to 133.
Answer: The flow rate is 133 mL per hour.

Correct Answer is ["A","C","E","F","G"]
Explanation
Choice A reason: Weight loss is indicative of hypermetabolism caused by excessive thyroid hormone production. The increased metabolic rate leads to higher energy consumption, resulting in unintentional weight loss even if the patient maintains or increases their food intake.
Choice B reason: Begins to cry when he tells you he recently lost his wife. Emotional responses, such as crying, can be associated with personal loss and grief but are not directly linked to hypermetabolism or excess thyroid hormone. This statement reflects the patient's emotional state rather than a physiological manifestation of hyperthyroidism.
Choice C reason: Hyperactive bowel sounds are a common manifestation of hypermetabolism due to hyperthyroidism. The increased metabolic rate accelerates gastrointestinal motility, resulting in hyperactive bowel sounds and sometimes diarrhea.
Choice D reason: 1+ pitting edema noted in bilateral lower extremities is related to fluid retention and heart failure rather than hypermetabolism. Edema is not a typical manifestation of hyperthyroidism and is more indicative of cardiovascular or renal issues.
Choice E reason: A heart rate of 124 (tachycardia) is a common finding in patients with hyperthyroidism. Excess thyroid hormones increase the heart rate and cardiac output, leading to symptoms such as palpitations and tachycardia.
Choice F reason: Bounding radial pulses are indicative of increased cardiac output and stroke volume, which are common in hyperthyroidism due to the hypermetabolic state induced by excess thyroid hormones. This leads to strong and forceful pulses.
Choice G reason: Anxious and restless behavior is a manifestation of the increased adrenergic activity associated with hyperthyroidism. Excess thyroid hormones stimulate the nervous system, leading to symptoms such as anxiety, restlessness, and irritability.
Correct Answer is B
Explanation
Choice A reason: Aggressive physical therapy is not a treatment for Addison's disease. While physical therapy can be beneficial for certain conditions, it does not address the hormonal deficiencies that are characteristic of Addison's disease.
Choice B reason: Lifelong hormone therapy with glucocorticoids and mineralocorticoids is the standard treatment for Addison's disease. This involves taking medications to replace the hormones that the adrenal glands are not producing enough of, specifically glucocorticoids (such as hydrocortisone, prednisone, or dexamethasone) and mineralocorticoids (such as fludrocortisone). These medications help to maintain normal hormone levels in the body, manage symptoms, and prevent adrenal crises.
Choice C reason: Diuretics are not typically used as a primary treatment for Addison's disease. They are used to manage fluid balance and blood pressure in other conditions, but they do not replace the deficient hormones in Addison's disease.
Choice D reason: Lifelong insulin treatment is used for managing diabetes mellitus, not Addison's disease. Addison's disease involves adrenal hormone deficiencies, which are treated with hormone replacement therapy, not insulin.
