The healthcare provider prescribes magnesium sulfate 300 mg/hour IV. The IV bag is contains magnesium sulfate 4 grams in dextrose 5% in water (DW) 500 mL. How many mL/hour should the nurse set the infusion pump? (Enter numerical value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["37.5"]

Convert grams to milligrams: 4 grams = 4000 mg

Determine the concentration of magnesium sulfate in the solution: 4000 mg / 500 mL = 8 mg/mL

Calculate the volume needed to deliver 300 mg/hour:

300 mg/hour ÷ 8 mg/mL = 37.5 mL/hour

Therefore, the nurse should set the infusion pump to deliver 37.5 mL/hour.

Correct Answer is C

Explanation

A. Do not take the medication more than once every 8 hours:
Diphenhydramine is typically dosed every 4 to 6 hours, not just once every 8 hours. However, this instruction is less critical compared to addressing the safety concerns related to drowsiness.

B. Take the medication with food to prevent gastric upset:
Diphenhydramine is generally not known to cause significant gastric upset, so this instruction is less critical. The primary concern with diphenhydramine is its sedative effects rather than gastrointestinal issues.

C. Avoid driving, since this medication causes drowsiness:
Diphenhydramine is known to cause significant drowsiness and sedation. Advising the client to avoid driving is crucial to prevent accidents and ensure their safety, making this the most important instruction.

D. Use sugarless candy or gum to help prevent a dry mouth:
While diphenhydramine can cause dry mouth, using sugarless candy or gum is a helpful but secondary instruction. The primary concern with diphenhydramine is its sedative effect, which affects the client's ability to drive safely.

A. The viral load can be decreased to an undetectable level. B. Antiretroviral medication prevents the transmission of the virus. C. The medications can decrease acquired immunodeficiency syndrome (AIDS) related complications. D. HIV infection is not cured by the antiretroviral regimen.

Correct Answer is B

Explanation

A. The viral load can be decreased to an undetectable level:
This statement is accurate. Antiretroviral medications can reduce the viral load in the blood to undetectable levels, which helps in managing HIV effectively.

B. Antiretroviral medication prevents the transmission of the virus:
This statement is misleading. While antiretroviral medications are effective in managing HIV and can reduce the viral load to undetectable levels, they do not entirely prevent the transmission of the virus. Safe practices, including the use of condoms and pre-exposure prophylaxis (PrEP), are also necessary to reduce transmission risk.

C. The medications can decrease acquired immunodeficiency syndrome (AIDS) related complications:
This is correct. Antiretroviral therapy helps manage HIV, preventing the progression to AIDS and reducing the likelihood of complications associated with AIDS.

D. HIV infection is not cured by the antiretroviral regimen:
This is true. Current antiretroviral therapies effectively control HIV and prevent progression to AIDS, but they do not cure the infection. Ongoing treatment is necessary to maintain viral suppression and overall health.
