The healthcare provider prescribes cefuroxime 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 ["10"]

To calculate the volume in mL to administer, use the formula:

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

Step 1: Convert the prescribed dose to milligrams
The prescribed dose is 5 grams.

Convert grams to milligrams:

5 grams × 1000 mg/gram = 5000 mg

Step 2: Divide by the concentration
The available concentration is 500 mg/mL.

Calculate the volume:

Volume (mL) = 5000 mg / 500 mg/mL = 10 mL

The nurse should administer 10 mL.

Correct Answer is C

Explanation

C. When providing health teaching to older adult clients, using everyday language is crucial. Older adults may have varying levels of health literacy and cognitive abilities, so using simple, clear language facilitates better understanding and comprehension of the information being provided.

A. Underlining key words on the written information may be helpful for emphasizing important points, but it is not as critical as using everyday language to enhance understanding

B. Speaking loudly and facing the client may not be necessary for all older adult clients and could even be perceived as patronizing or disrespectful.

D. Providing a very well-lit meeting space is important for optimizing visual acuity, especially for older adults who may have age-related changes in vision. However, while adequate lighting is beneficial, it is not as critical

A. Switch to a non-rebreather mask. B. Verify placement of pulse oximeter. C. Increase the oxygen to 3 L/minute. D. Remove nasal cannula.

Correct Answer is B

Explanation

B. When the oxygen saturation is lower than expected, the nurse's first action should be to verify the accuracy of the reading by ensuring the proper placement and functioning of the pulse oximeter. This involves checking that the pulse oximeter probe is securely attached to the client's finger or other appropriate site and that there are no obstructions or interference affecting the reading.

A. A non-rebreather mask delivers higher concentrations of oxygen compared to a nasal cannula and is typically used when a client requires higher levels of oxygen supplementation. However, switching to a non-rebreather mask may not be appropriate without further assessment.

C. Increasing the oxygen flow rate to 3 L/minute would deliver a higher concentration of oxygen to the client, potentially improving oxygen saturation. However, increasing the oxygen flow should be done cautiously and based on clinical assessment to avoid oxygen toxicity.

D. Removing the nasal cannula would deprive the client of supplemental oxygen, which may not be appropriate if the client's oxygen saturation is already low. Oxygen supplementation is typically provided to improve oxygenation and support vital organ function.
