A nurse is preparing to administer erythromycin 2 g PO daily in equally divided doses every 6 hr. How many mg should the nurse administer per dose? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

A. 0.45% sodium chloride: 0.45% sodium chloride solution, also known as half-normal saline, is a hypotonic solution used for rehydration and maintenance fluid therapy. However, in cases of
major burns where there is a significant loss of fluid and electrolytes, isotonic solutions are generally preferred.
B. Lactated Ringer's: Lactated Ringer's solution is an isotonic crystalloid solution that closely resembles the electrolyte composition of extracellular fluid. It is commonly used for fluid resuscitation in clients with major burns to replace lost fluids and electrolytes and restore
intravascular volume.

C. Dextrose 5% in water: Dextrose 5% in water is a hypotonic solution used primarily for hydration in clients with normal electrolyte levels or as a vehicle for administering medications.
It is not typically used for fluid resuscitation in clients with major burns, as it does not adequately replace lost electrolytes.
D. Dextrose 5% in 0.45% sodium chloride: This solution combines dextrose 5% and 0.45% sodium chloride and is used for maintenance fluid therapy and mild dehydration. However, in cases of major burns where there is significant fluid and electrolyte loss, isotonic solutions like lactated Ringer's or normal saline are preferred for fluid resuscitation.

A. The correct order is

1. wipe off tops of insulin vials with alcohol sponge.
2. draw back amount of air into the syringe that equals total dose.
3. inject air equal to NPH dose into NPH vial. ...
4. air equal to regular dose into regular vial.
5. invert regular insulin bottle and withdraw regular insulin dose.
6. without adding more air into NPH vial, carefully withdraw NPH dose

B. Withdraw the regular insulin from the vial: This step should occur after injecting air into the regular insulin vial. The nurse should draw up the regular insulin before drawing up the NPH
insulin.

C. Inject air into the regular insulin vial: Inject air into the regular insulin vial is not thecorrect first step to avoid contamination of the clear insulin with cloudy insulin..
D. Withdraw the NPH insulin from the vial: This step should occur after withdrawing the regular insulin. The nurse should draw up the NPH insulin after drawing up the regular insulin to ensure the correct sequence and dosage.
