The nurse retrieves hydromorphone "4 mg/mL" from the electronic medication system, for a patient who is receiving hydromorphone 3 mg IM every 6 hours PRN for severe pain. How many mL should the nurse administer to the patient? (Enter the numerical value only. If rounding is required, round to the nearest tenth.)

The nurse needs to administer hydromorphone 3 mg to the patient. The concentration of the hydromorphone solution is 4 mg/mL. To find out how many mL the nurse should administer, we can use the formula:

Answer and Explanation

The Correct Answer is ["0.8"]

Amount (mg) ÷ Concentration (mg/mL) = Volume (mL)

Step 1: The amount of hydromorphone the patient needs is 3 mg. Step 2: The concentration of the hydromorphone solution is 4 mg/mL. Step 3: Substitute the values into the formula: 3 mg ÷ 4 mg/mL.

Step 4: Calculate the volume: 3 ÷ 4 = 0.75 mL. 0.8 rounded to the nearest tenth

Correct Answer is D

Explanation

Choice A reason: Dizziness is not typically associated with perineal care and is not relevant to the instructions.

Choice B reason: Advising to keep the pubic area shaved is not a standard part of perineal care instructions and is a personal choice.

Choice C reason: The statement about not retracting the foreskin is incorrect; the foreskin should be retracted gently for cleaning and then returned to its normal position to prevent infection.

Choice D reason: It is important to inform the caregiver that an erection may occur as a natural reflex during perineal care, and it does not indicate any sexual intent. This helps prepare the caregiver to handle the situation professionally.

A. Serum potassium: 3.5 mEq/L (3.5 mmol/L), serum sodium: 142 mEq/L (142 mmol/L) B. Serum potassium: 4.5 mEq/L (4.5 mmol/L), serum sodium: 140 mEq/L (140 mmol/L) C. Serum potassium: 5.0 mEq/L (5.0 mmol/L), serum sodium: 138 mEq/L (138 mmol/L) D. Serum potassium: 3.0 mEq/L (3.0 mmol/L), serum sodium: 149 mEq/L (149 mmol/L)

Correct Answer is A

Explanation

Choice A reason: The results are within the normal reference range for both potassium and sodium, which is expected unless the client's condition has led to significant electrolyte imbalances.

Choice B reason: A serum potassium level of 4.5 mEq/L is at the higher end of the normal range, which might not be expected in a client with vomiting and diarrhea, conditions that often lead to lower potassium levels.

Choice C reason: A serum potassium level of 5.0 mEq/L is at the upper limit of the normal range and could indicate hyperkalemia, especially in the context of severe dehydration.

Choice D reason: A serum sodium level of 149 mEq/L is slightly above the normal range and could indicate hypernatremia, which may occur in dehydration but would require further assessment and intervention.
