The healthcare provider prescribes streptomycin 200 mg intramusculary every 12 hours. The vial is labeled, "Streptomycin 1 gram/2.5 mL". How many milliliters should the nurse administer? (Enter numerical value only. (If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["0.5"]

· Convert grams to milligrams: 1 gram = 1000 mg

· Determine the concentration: The vial contains 1000 mg of streptomycin in 2.5 mL of solution.

· Set up a proportion: (Desired dose / Concentration) Volume = Amount to administer

(200 mg / 1000 mg) x 2.5 mL = X mL

· Solve for X: 0.2 x 2.5 mL = 0.5 mL

Correct Answer is B

Explanation

A. Record a palpable systolic pressure of 90 mm Hg is premature because the nurse has not yet completed the process of determining the systolic blood pressure.

B. Inflate blood pressure cuff to 120 mm Hg is the correct action. The nurse should inflate the cuff 30 mm Hg above the point where the radial pulse disappears to ensure accurate measurement of the systolic blood pressure.

C. Release the manometer valve immediately would not allow the nurse to accurately determine the systolic blood pressure. The valve should be released slowly to palpate the return of the pulse.

D. Document the absence of the radial pulse is unnecessary because the disappearance of the pulse is a normal part of the procedure when obtaining a systolic blood pressure by palpation.

A. Self-care deficit. B. Risk for infection. C. Impaired physical mobility. D. Risk for impaired skin integrity.

Correct Answer is D

Explanation

A. Self-care deficit might apply if the client is unable to perform foot care independently. However, the priority concern is addressing the potential complications of neuropathy, such as skin breakdown, before considering assistance with care.

B. Risk for infection is a valid concern, especially if skin integrity is compromised. However, infection prevention depends on maintaining intact skin, making skin integrity the more immediate priority.

C. Impaired physical mobility may contribute to challenges in foot care but does not directly address the risk posed by neuropathy, which primarily affects sensory perception and increases vulnerability to unnoticed injuries.

D. Risk for impaired skin integrity is the priority because neuropathy reduces sensation in the feet, increasing the likelihood of unnoticed injuries, pressure sores, or burns. Early identification and prevention of skin damage are essential for avoiding complications.
