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. Hold both medications until contacting the healthcare provider (HCP): A total calcium level of 14 mg/dL is critically high and indicates hypercalcemia. Continuing calcitriol or calcium carbonate could worsen the hypercalcemia, so both medications should be held and the HCP contacted immediately for further orders.

B. Hold the calcitriol, but administer the calcium carbonate as scheduled: Calcium carbonate increases serum calcium levels, and administering it would exacerbate the already dangerously high calcium level. It should not be given until the situation is reassessed.

C. Hold the calcium carbonate, but administer the calcitriol as scheduled: Calcitriol promotes intestinal absorption of calcium, which could further elevate serum calcium levels. Giving calcitriol would be unsafe until the client’s calcium status is re-evaluated.

D. Administer both prescribed medications as scheduled: Administering both medications would significantly increase the risk of severe hypercalcemia complications, such as cardiac arrhythmias or neurologic changes, and must be avoided until new instructions are received.

A. Expectorating bronchial secretions. B. Reports reduced nasal discharge. C. Able to sleep through the night. D. Denies having coughing spells.

Correct Answer is D

Explanation

A. Expectorating bronchial secretions: This outcome is more closely associated with expectorants, which loosen mucus in the airways. Antitussives, by contrast, suppress the cough reflex and are not intended to increase mucus clearance or productive coughing.

B. Reports reduced nasal discharge: Reduced nasal discharge is typically an effect of decongestants or antihistamines, not antitussive medications. Antitussives target the cough reflex, not nasal secretions.

C. Able to sleep through the night: While improved sleep may result from reduced coughing, it is a secondary and nonspecific outcome. The ability to sleep could be influenced by other factors such as overall symptom relief, not necessarily the effectiveness of the antitussive alone.

D. Denies having coughing spells: Antitussives are designed to suppress the cough reflex, particularly in cases of dry, nonproductive cough. A report of no more coughing spells directly reflects the intended therapeutic effect of the medication.
