Examine the following patient data for a patient who has been prescribed vancomycin.
The nurse is evaluating a patient after administering several doses of Vancomycin IV. Which of the following changes would indicate a therapeutic response to the medication? (Select all that apply)

WBC count of 16,000/mm

BUN level of 42 mg/dl

Blood pressure reading of 95/64

Body temperature of 101.8F

Answer and Explanation

Correct Answer : A,C,D

Choice A rationale:

A WBC count of 16,000/mm is higher than the normal range of 5,000 to 10,000 cells/mm. This indicates that the body is fighting an infection, which is a common reason for prescribing Vancomycin. Therefore, a high WBC count could indicate a therapeutic response to the medication as it suggests that the body’s immune system is actively fighting the infection.

Choice B rationale:

A BUN level of 42 mg/dl is higher than the normal range of 7 to 20 mg/dL3456. Elevated BUN levels can indicate kidney damage or disease, which is not a desired therapeutic response to Vancomycin. Vancomycin can be nephrotoxic, and its use requires careful monitoring of kidney function. Therefore, a high BUN level does not indicate a therapeutic response to the medication. Choice C rationale:

A blood pressure reading of 95/64 is considered normal. Maintaining normal blood pressure is important for overall health and can indicate that the patient’s body is responding well to the medication. Therefore, a blood pressure reading within the normal range could indicate a therapeutic response to Vancomycin.

Choice D rationale:

A body temperature of 101.8F is considered a fever14. Fever is a common response to infection and can indicate that the body is fighting off an infection, which is a common reason for prescribing Vancomycin. Therefore, a high body temperature could indicate a therapeutic response to the medication as it suggests that the body’s immune system is actively fighting the infection.

Correct Answer is ["50 "]

Explanation

The question is about calculating the volume of phenytoin oral solution that the nurse should administer per dose. The client is prescribed 250 mg of phenytoin and the available solution has a concentration of 25 mg/5 mL.

Let’s calculate the volume step by step:

Step 1: Identify the prescribed dose and the concentration of the available medication. The prescribed dose is 250 mg and the concentration of the available medication is 25 mg/5 mL.

Step 2: Set up the calculation. We want to find out how many mL correspond to the prescribed dose. We can set up the calculation as follows: (Prescribed dose ÷ Concentration) × Volume.

Step 3: Substitute the known values into the calculation. This gives us: (250 mg ÷ 25 mg/5 mL).

Step 4: Perform the division operation first due to the order of operations (BIDMAS/BODMAS). This gives us: (250 mg ÷ 5 mg/mL).

Step 5: Perform the final calculation. This gives us: 50 mL.

So, the nurse should administer 50 mL of the phenytoin oral solution per dose.

Please note that this calculation assumes that the prescribed dose (250 mg) is to be administered in one go. If the dose is to be split over the day, the volume to be administered would change accordingly.

A. Macrolides B. Sulfonamides C. Carbapenems D. Tetracyclines

Correct Answer is B

Explanation

Choice A rationale:

Macrolides Macrolides, such as erythromycin and azithromycin, are a class of antibiotics that are typically used to treat infections caused by gram-positive bacteria and some respiratory tract infections. They are not the first line of treatment for urinary tract infections.

Choice B rationale:

Sulfonamides Sulfonamides, such as sulfamethoxazole, are often used to treat urinary tract infections. They work by stopping the growth of bacteria. Sulfonamides are often combined with other antibiotics like trimethoprim to increase their effectiveness. This combination is commonly known as co-trimoxazole.

Choice C rationale:

Carbapenems Carbapenems are a class of antibiotics that are usually reserved for serious infections caused by gram-negative bacteria. While they can be used to treat a variety of infections, they are not typically the first choice for urinary tract infections.

Choice D rationale:

Tetracyclines Tetracyclines are a group of broad-spectrum antibiotics that are effective against a wide range of bacteria. However, they are not typically used for urinary tract infections. They are more commonly used for infections such as acne, chlamydia, and Lyme disease.
