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 A

Explanation

Choice A rationale:

Rifampin Rifampin is an antitubercular drug that is effective against all strains of Mycobacterium tuberculosis. It works by inhibiting the synthesis of RNA in the bacteria, preventing them from reproducing. However, it does not typically cause a decrease in visual acuity.

Choice B rationale:

Ethambutol Ethambutol is an antitubercular drug that can cause ocular toxicity in the form of visual field changes. It is known to induce toxic optic neuropathy, which is quite common and can lead to a decrease in visual acuity. Patients on Ethambutol therapy are advised to report any changes in visual acuity or eye discomfort immediately to their healthcare provider.

Choice C rationale:

Streptomycin Streptomycin is an aminoglycoside antibiotic used in the treatment of tuberculosis. It works by inhibiting protein synthesis in bacteria. While it can cause side effects such as ototoxicity and nephrotoxicity, it is not typically associated with a decrease in visual acuity.

Choice D rationale:

Isoniazid Isoniazid is a first-line antitubercular drug that works by inhibiting the synthesis of mycolic acids in the cell wall of Mycobacterium tuberculosis. While it can cause peripheral neuropathy, it is not typically associated with a decrease in visual acuity.

A. I will shake the insulin vial vigorously to mix. B. I should inject the insulin into my abdominal area. C. I should increase my insulin when I exercise. D. I will freeze unopened insulin vials.

Correct Answer is B

Explanation

Choice A rationale:

Shaking the insulin vial vigorously is not recommended. It can lead to the formation of bubbles, which can affect the accuracy of the dose. Instead, insulin vials should be gently rolled between the hands to mix.

Choice B rationale:

Injecting insulin into the abdominal area is indeed a recommended practice. The abdomen is a preferred site for insulin injection because it has a faster absorption rate compared to other areas. This can help to more effectively regulate blood glucose levels.

Choice C rationale:

Exercise typically lowers blood glucose levels, so insulin doses may need to be reduced to prevent hypoglycemia. Clients should monitor their blood glucose closely and adjust insulin as directed by their healthcare provider.

Choice D rationale:

Freezing unopened insulin vials is not advised. Freezing can disrupt the insulin structure, rendering it ineffective. Insulin should be stored in a refrigerator at a temperature between 2°C and 8°C (36°F and 46°F). Once opened, it can be kept at room temperature for up to 28 days.
