A nurse receives a telephone prescription from the provider, who states, "Four milligrams of morphine diluted with five milliliters of sterile water, intravenously each morning at nine o'clock before client dressing changes." Which of the following entries by the nurse indicates correct transcription of the prescription?

MSO4 4 mg IV bolus daily before dressing changes and dilute with 5 cc of water.

Morphine 4 mg IV bolus daily at 0900 before dressing changes, dilute medication with 5 mL of sterile water.

Morphine 4 mg IV bolus Q.D. before dressing changes and dilute with 5 cc of sterile water.

MSO4 4 mg IV bolus daily @9 AM, dilute with 5 mL of sterile water.

Answer and Explanation

The Correct Answer is B

Choice A rationale:

While the abbreviation "MSO4" represents morphine sulfate, it is safer to spell out the medication name to prevent misinterpretation. Also, the use of "cc" for volume and lack of clarity in timing make this option less desirable.

Choice B rationale:

(Correct Choice) This option correctly identifies the medication, includes the dose (4 mg), specifies the route (IV), indicates the timing (daily at 0900 before dressing changes), and provides instructions for dilution (5 mL of sterile water).

Choice C rationale:

Using "Q.D." is an abbreviation for "every day" and might lead to confusion due to unfamiliarity. Additionally, using "cc" instead of "mL" and lack of clarity in timing reduce the accuracy of this transcription.

Choice D rationale:

Using "MSO4" and "cc" are potential sources of confusion. Also, the abbreviation "@9 AM" might not be universally understood, and "mL" is a more appropriate unit for volume.

Correct Answer is C

Explanation

Choice A rationale:

Exerting firm pressure when placing the probe (Choice A) is not recommended because it can potentially compress the blood vessels and impede blood flow. This can lead to inaccurate readings and compromise the assessment of the pedal pulses in a client with peripheral vascular disease.

Choice B rationale:

Applying the probe to the exterior aspect of the ankle (Choice B) is not the standard approach for assessing pedal pulses. The pedal pulses are typically assessed on the dorsal (top) and posterior (back) aspects of the foot, as well as the lateral (side) aspects of the ankle. Placing the probe on the exterior aspect of the ankle might not yield accurate results.

Choice C rationale:

Moving the probe until a whooshing sound is present (Choice C) is the correct action when using a Doppler ultrasound stethoscope to assess pedal pulses. The whooshing sound, known as "Doppler sound," indicates the presence of blood flow. The nurse should gently maneuver the probe until this sound is heard, allowing for an accurate assessment of the pulses and blood flow status.

Choice D rationale:

Holding the probe at a 30° angle to the blood vessel (Choice D) is not a standard practice for assessing pedal pulses with a Doppler ultrasound stethoscope. The nurse should place the probe directly over the pulse site and adjust its position until the Doppler sound is detected.

A. Select an injection site on the abdomen 5 cm (2 in) from the umbilicus. B. Expel the air bubble in a prefilled syringe before injecting the medication. C. Aspirate prior to injecting the medication. D. Insert the needle at a 15° angle.

Correct Answer is B

Explanation

Choice A rationale:

Selecting an injection site on the abdomen 5 cm (2 in) from the umbilicus might be an appropriate instruction for some subcutaneous injections, but the specific injection site can vary based on the medication and client's needs. This choice is not a universal instruction for all subcutaneous injections.

Choice B rationale:

Expelling the air bubble from a prefilled syringe before injecting the medication is essential to ensure accurate dosing. Air bubbles can displace medication and lead to underdosing. This step is crucial for safe and effective administration.

Choice C rationale:

Aspirating prior to injecting medication is a technique used for intramuscular injections to ensure the needle is not in a blood vessel. However, for subcutaneous injections, aspirating is not necessary or recommended, as it can cause tissue damage and discomfort.

Choice D rationale:

Inserting the needle at a 15° angle is not a standard practice for subcutaneous injections. Subcutaneous injections are typically administered at a 45° or 90° angle, depending on the needle length and client's body composition. A 15° angle would not ensure proper medication delivery.
