The healthcare provider (HCP) prescribes cefuroxime 1.5 grams every 8 hours IM for a client with pneumonia. The available vial is labeled, "Cefuroxime 500 mg/mL." How many mL should the nurse administer to this client?

(Enter numerical value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["3"]

Convert grams to milligrams:

1.5 g x 1000 mg/g = 1500 mg

Calculate the volume to administer:

Volume (mL) = Desired dose (mg) / Available concentration (mg/mL)

= 1500 mg / 500 mg/mL

= 3 mL

Correct Answer is A

Explanation

A. Determine what time the dose is taken: Dextroamphetamine-amphetamine is a stimulant that can interfere with sleep if taken too late in the day. The timing of the dose is crucial because early morning dosing minimizes insomnia, making this the most important initial assessment.

B. Ask about the client's bedtime routine: While bedtime routines can influence sleep quality, stimulant medication timing has a much stronger direct effect on insomnia, making this a secondary consideration after reviewing dose timing.

C. Inquire about perceived anxiety: Anxiety can contribute to sleep difficulties, but in clients taking stimulants, medication effects are a more likely cause. Addressing medication-related factors takes priority over psychological causes in this case.

D. Determine daily caffeine intake: Caffeine may worsen insomnia, but stimulant medications are generally a stronger factor in causing sleep disturbances. Assessing caffeine use is important but not the first priority compared to reviewing medication timing.

A. Avoid driving or operating machinery. B. Take a missed dose as soon as possible. C. Standing slowly when getting up from bed. D. Avoid intake of alcoholic beverages.

Correct Answer is C

Explanation

A. Avoid driving or operating machinery: Drowsiness and dizziness can occur with atenolol, especially when initiating therapy, but these effects are usually mild. While it's reasonable to use caution initially, this is not the most critical teaching point compared to orthostatic safety.

B. Take a missed dose as soon as possible: Although this may seem helpful, patients should not double doses or take extra doses close together. If a significant amount of time has passed, the missed dose may need to be skipped to prevent bradycardia or hypotension.

C. Standing slowly when getting up from bed: Atenolol, a beta-blocker, can cause orthostatic hypotension, especially in older adults. Teaching the client to rise slowly helps reduce the risk of dizziness and falls, making this a high-priority safety instruction following discharge.

D. Avoid intake of alcoholic beverages: Alcohol may enhance the hypotensive effects of beta-blockers, but moderate consumption is not strictly contraindicated. This advice is relevant but less urgent than preventing injury from orthostatic hypotension.
