A physician prescribes Vancomycin 20 mg/kg intravenous (IV). The patient weighs 110 lbs. The medication is available in vials which contain 500 mg per 8 mL. What should the nurse withdraw from the vial? (round to the nearest whole number)

Answer and Explanation

The Correct Answer is ["16"]

To calculate the dosage of Vancomycin, first convert the patient's weight from pounds to kilograms, knowing that 1 kg equals 2.2 lbs. The patient weighs 110 lbs, which is equivalent to 50 kg (110 lbs / 2.2). Next, multiply the patient's weight in kilograms by the prescribed dosage of 20 mg/kg, resulting in a total dosage of 1000 mg (50 kg * 20 mg/kg). Since the vials contain 500 mg per 8 mL, divide the total dosage required by the amount per vial to find out how many milliliters should be withdrawn. This results in 16 mL (1000 mg / (500 mg/8 mL)).

Correct Answer is A

Explanation

A. Timolol is a beta-blocker that can be absorbed systemically, leading to side effects such as bradycardia and hypotension, which require monitoring.

B. Tachycardia and dry cough are not common side effects of timolol; dry cough is more associated with ACE inhibitors.

C. Scleral injection and tearing are not common side effects and are not expected with timolol use.

D. Changes in eye pigmentation are more commonly seen with prostaglandin analogs, not with beta-blockers like timolol.

A. Initiate a 1:1 observation status B. Point out the behavior as unacceptable C. Ask the patient why they are behaving that way D. Have the patient return to his room

Correct Answer is B

Explanation

A. 1:1 observation may be excessive unless the behavior is persistent and unmanageable.

B. Pointing out the behavior as unacceptable provides immediate feedback and helps the patient understand social boundaries, which can be challenging post-brain injury. This approach is direct and respectful, focusing on redirection rather than punishment.

C. Asking why may not be effective, as the patient may lack insight into their behavior due to the brain injury.

D. Having the patient return to their room could seem punitive and does not address the need for behavior modification.
