A nurse is teaching a client about self-administering a subcutaneous injection to the abdomen. Which of the following instructions should the nurse include?
Select an injection site on the abdomen 5 cm (2 in) from the umbilicus.
Expel the air bubble in a prefilled syringe before injecting the medication.
Aspirate prior to injecting the medication.
Insert the needle at a 15° angle.
The Correct Answer is B
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.

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.
Correct Answer is B
Explanation
Choice A rationale:
Instructing the client's loved ones that the client should not have fresh flowers in their room (Choice A) is not a necessary action for rubella isolation. Rubella is transmitted through respiratory droplets, and the prohibition of fresh flowers is not a relevant precaution.
Choice B rationale:
Wearing a surgical mask when within 0.9 m (3 feet) of the client (Choice B) is the correct action. Rubella is an airborne disease, and wearing a surgical mask helps prevent the spread of infectious respiratory droplets to the nurse and other individuals.
Choice C rationale:
Placing the client in a room with negative-airflow pressure (Choice C) is not specifically indicated for rubella isolation. Negative-airflow pressure rooms are typically used for diseases that require strict airborne precautions, such as tuberculosis.
Choice D rationale:
Instructing the client that visitors will not be allowed while they are in isolation (Choice D) is not entirely accurate for rubella isolation. While isolation precautions are necessary, visitors can enter the room if they are properly protected, including wearing masks and following infection control protocols.
