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 ["C","E","F"]
Explanation
Choice A reason: Applying a clean, dry dressing over the VTE/DVT site is not necessary. VTE/DVT usually involves deep veins where there are no visible wounds requiring dressings. This instruction is irrelevant to the management and discharge instructions for a patient with DVT on anticoagulant therapy.
Choice B reason: Monitoring activated partial thromboplastin time (aPTT) results is relevant for heparin therapy, not for warfarin. Warfarin therapy is monitored using the international normalized ratio (INR). Therefore, this instruction is not appropriate for a patient being discharged on warfarin.
Choice C reason: Administering the warfarin dose at the same time each day is crucial for maintaining consistent blood levels of the medication, ensuring its effectiveness. It helps to maintain steady anticoagulation and reduces the risk of complications associated with fluctuating blood levels of warfarin.
Choice D reason: Instructing the patient to take aspirin or NSAIDs as needed for pain is inappropriate because these medications can increase the risk of bleeding when taken with warfarin. Patients on warfarin should avoid these medications and use alternatives like acetaminophen (Tylenol) for pain relief.
Choice E reason: Advising the patient to use electric razors, not straight razors, when shaving is important to prevent cuts and bleeding. Warfarin increases the risk of bleeding, and using an electric razor minimizes the chance of nicks and cuts that could lead to significant bleeding.
Choice F reason: Monitoring the level of anticoagulation with warfarin using INR results is essential. Regular INR monitoring ensures that the patient maintains a therapeutic level of anticoagulation and helps prevent both clotting and bleeding complications. Adjustments to the warfarin dose are made based on INR results.
Correct Answer is ["B","C"]
Explanation
Choice A reason: Low T4 levels do not indicate hyperthyroidism. In fact, low levels of T4 are typically associated with hypothyroidism, a condition in which the thyroid gland does not produce enough thyroid hormones.
Choice B reason: High T4 levels are indicative of hyperthyroidism. In hyperthyroidism, the thyroid gland is overactive and produces excessive amounts of thyroid hormone (T4), leading to elevated T4 levels in the blood.
Choice C reason: Low TSH levels are also indicative of hyperthyroidism. The pituitary gland secretes TSH to regulate thyroid hormone production. When thyroid hormone levels are high, as in hyperthyroidism, the pituitary gland reduces TSH secretion, resulting in low TSH levels.
Choice D reason: High TSH levels are not associated with hyperthyroidism. Elevated TSH levels are more commonly seen in hypothyroidism, where the thyroid gland is underactive, and the pituitary gland compensates by increasing TSH production to stimulate the thyroid gland.
