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.)
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 ["A","B","D","F"]
Explanation
A. No known allergies:
Having no known allergies is a significant factor in determining the safety of administering vancomycin, as it reduces the risk of an allergic reaction. Vancomycin can cause allergic reactions or hypersensitivity, so it’s important to ensure the client is not allergic to this medication.
B. Peripheral IV in large vein:
Vancomycin should be administered through a large vein because it can be irritating to smaller veins and potentially cause thrombophlebitis or vein damage. Using a large vein helps to minimize these risks and ensure safe administration.
C. Potassium 4.4 mEq/L (4.4 mmol/L):
While potassium levels are important to monitor, they are not directly related to the safety of administering vancomycin. Vancomycin does not have a direct impact on potassium levels, so this finding does not specifically indicate the safety of vancomycin administration.
D. Used for prophylaxis:
Vancomycin is often used as prophylaxis in certain surgical procedures to prevent infection, especially in cases where there is a high risk of methicillin-resistant Staphylococcus aureus (MRSA) infection. The use of vancomycin for prophylaxis is a common practice and indicates it is being administered for an appropriate reason.
E. Blood urea nitrogen 17 mg/dL (6.07 mmol/L):
A blood urea nitrogen (BUN) level of 17 mg/dL is slightly elevated but not necessarily a contraindication for vancomycin administration. However, vancomycin can impact kidney function, so it is important to monitor renal function but not the sole factor in determining safety.
F. Dosage in safe range:
Ensuring the dosage of vancomycin is within the safe range is crucial for preventing toxicity and achieving therapeutic efficacy. This is an essential consideration when administering the medication to avoid adverse effects and ensure effective treatment.
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.
