A nurse is administering medications to a client who weighs 132 lb. The prescription reads chloramphenicol, 50mg/kg/day in 4 divided doses. Available is chloramphenicol 100 mg/mL. How many mL should the nurse give with each dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["7.5"]
Convert the client's weight from pounds to kilograms. We can use the formula 1 kg = 2.2 lb. So, 132 lb / 2.2 = 60 kg.
Calculate the total daily dose of chloramphenicol for the client. We can use the formula Dose (mg) = Weight (kg) x Dosage (mg/kg). So, 60 kg x 50 mg/kg = 3000 mg.
Divide the total daily dose by 4 to get the dose for each administration. So, 3000 mg / 4 = 750 mg.
Calculate the volume of chloramphenicol solution needed for each dose. We can use the formula Volume (mL) = Dose (mg) / Concentration (mg/mL). So, 750 mg / 100 mg/mL =
7.5 mL.
Round the answer to the nearest tenth. So, the nurse should give 7.5 mL of chloramphenicol solution with each dose.

Correct Answer is C
Explanation
A. “I can cut the patches in half to save money": Cutting nitroglycerin patches is not recommended as it can alter the medication's release rate and efficacy. Therefore, this statement indicates a misunderstanding and should be corrected.
B. “I will apply a new patch to the same site whenever I replace it": Rotating patch sites is essential to prevent skin irritation and tolerance development. Therefore, this statement indicates a misunderstanding and should be corrected.
C. “I will take the patch off after dinner every night": This statement demonstrates understanding because nitroglycerin patches are typically worn for a certain number of hours (e.g., 12-14 hours) and then removed for a drug-free interval to prevent tolerance development.
D. "I can put a second patch on if I have chest pain": Applying multiple nitroglycerin patches simultaneously can lead to excessive vasodilation and hypotension, which can be dangerous. Therefore, this statement indicates a misunderstanding and should be corrected.
Correct Answer is A
Explanation
A. Hypotension: Hypotension can occur as an adverse effect of fentanyl, particularly if the client experiences excessive sedation or respiratory depression. Fentanyl is a potent opioid analgesic
that can cause vasodilation and a decrease in blood pressure, especially when used in high doses or in susceptible individuals.
B. Tachycardia: Tachycardia is not a typical adverse effect of fentanyl. Opioids like fentanyl typically cause bradycardia or have minimal effects on heart rate.
C. Diarrhea: Diarrhea is not a common adverse effect of fentanyl. Opioids more commonly cause constipation due to their effects on gastrointestinal motility.
D. Insomnia: Insomnia is not a typical adverse effect of fentanyl. Opioids typically cause sedation and can lead to drowsiness or somnolence, especially during initial use or when administered in high doses.
