The nurse prepares to administer promethazine 35 mg intramuscularly prescribed as needed for a client with cholecystitis who has severe nausea. The ampule label reads that the medication is available in 25 mg/mL. How many milliliters should the nurse administer?

Record your answer using one decimal place.

1.4

1.5

0.7

Answer and Explanation

The Correct Answer is B

Choice A rationale: this corresponds with 25 mg which is lower than the prescribed amount.

Choice B rationale: To answer this question, we need to use the formula: volume (mL) = dose (mg) / concentration (mg/mL). We plug in the given values: volume (mL) = 35 mg / 25 mg/mL. We simplify the fraction: volume (mL) = 7/5. We convert the fraction to a

decimal: volume (mL) = 1.4. Therefore, the nurse should administer 1.4 mL of promethazine.

Choice C rationale: this corresponds with 37.5 mg which is too high.

Choice D rationale: this corresponds with 17.5 mg which is too low.

Correct Answer is A

Explanation

Choice A rationale: This is because removing a large amount of fluid from the abdominal cavity can cause a sudden decrease in intra-abdominal pressure, which can lead to hypovolemia and hypotension. The body compensates by increasing the heart rate to maintain cardiac output and perfusion.

Choice B rationale: This is not directly related to paracentesis and may indicate other conditions.

Choice C rationale: This is not directly related to paracentesis and may indicate other conditions.

Choice D rationale: This is not directly related to paracentesis and may indicate other conditions.

A. intubation and mechanical ventilation. B. IV infusion of (Sandoglobulin). C. administration of methylprednisolone (Solu-Medrol). D. insertion of a nasogastric (NG) feeding tube

Correct Answer is B

Explanation

Choice A rationale: Intubation and mechanical ventilation may be needed if the respiratory muscles are affected by GBS, but this is not a routine intervention at this stage.

Choice B rationale: One of the main treatments of GBS is IV immunoglobulin therapy (IVIG), which involves infusing antibodies from donated blood plasma to block the harmful immune response that damages the nerves. Sandoglobulin is one of the brand names of IVIG used for GBS. IVIG can help shorten the duration and severity of the disease, and improve the recovery rate.

Choice C rationale: Methylprednisolone is a corticosteroid that can reduce inflammation, but it is not recommended for GBS, as it may worsen the condition or increase the risk of infection.

Choice D rationale: NG feeding tube may be required if the patient has difficulty swallowing, but this is also not a standard intervention at this time.
