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 C

Explanation

Choice A rationale: These symptoms are more indicative of diabetic ketoacidosis, not hypoglycemia.

Choice B rationale: Symptoms of increased urination, thirst, and hunger are more associated with hyperglycemia, not hypoglycemia.

Choice C rationale: These are classic signs of hypoglycemia and should be described to the client for early recognition and intervention.

Choice D rationale: These symptoms can occur in hypoglycemia but are less specific compared to sweating, cold, trembling, and tachycardia.

A. a Gloves should be worn during direct contact with the client's skin. B. No precautions in addition to standard precautions are necessary. C. Handwashing is required before and after contact with the client. D. A mask should be worn by anyone entering the client's room.

Correct Answer is A

Explanation

Choice A rationale: Gloves should be worn during direct contact with the client's skin. This is a standard precaution that applies to all clients, but especially to those with infectious diseases that can be transmitted through contact. Secondary syphilis is highly contagious and can be spread through direct contact with the skin lesions or mucous

membranes of an infected person.

Choice B rationale: This is incorrect because secondary syphilis requires more than standard precautions to prevent transmission.

Choice C rationale: This is incorrect because handwashing is a basic component of standard precautions and is not sufficient to prevent the spread of syphilis.

Choice D rationale: This is incorrect because a mask is not necessary for contact precautions, unless the client has respiratory symptoms or is undergoing aerosol- generating procedures.
