A nurse is assessing a client who received an IM antibiotic injection 15 min ago. Which of the following findings should the nurse identify as an indication of a possible anaphylactic reaction to the medication?
A feeling of swelling in the feet
Pain at the injection site
A sudden decrease in heart rate
A sharp decrease in blood pressure
The Correct Answer is D
A. A feeling of swelling in the feet:
Swelling in the feet is not a typical sign of an anaphylactic reaction to an IM antibiotic injection. Anaphylaxis usually involves more rapid and widespread symptoms that can affect various body systems.
B. Pain at the injection site:
Pain at the injection site is a common side effect of intramuscular (IM) injections and is not typically indicative of an anaphylactic reaction. Anaphylactic reactions are characterized by more systemic and severe symptoms.
C. A sudden decrease in heart rate:
An anaphylactic reaction typically involves an increase in heart rate rather than a decrease. The body's response to an allergen in an anaphylactic reaction often includes a rapid heart rate, as part of the systemic release of inflammatory mediators.
D. A sharp decrease in blood pressure:
This is the correct answer. Anaphylactic reactions can lead to a sudden and severe drop in blood pressure, which is a critical and life-threatening symptom. This is due to the release of vasodilatory substances and increased permeability of blood vessels, resulting in a decrease in blood volume within the vessels.

Correct Answer is D
Explanation
A. Loosen the client's bed linens:
For support surfaces to be effective, there must be minimal layering in between the device and the person. A single sheet that can be kept dry and crease free is optimal. Loosening linens can help make the client more comfortable by reducing pressure and friction on the skin, but it does not directly address the client's acute pain from a pressure injury.
B. Provide bright lights in the client's room:
Bright lights may not be directly relevant to managing acute pain from a pressure injury. In fact, some clients may prefer a dimly lit environment when experiencing pain. Therefore, this option is not the most appropriate for pain management in this case.
C. Massage the client's sacrum:
Massaging the client's sacrum is not recommended when there is a pressure injury, as this could further damage the tissue and exacerbate the injury.
D. Offer to play music in the client's room:
Music therapy is a widely recognized nonpharmacological intervention for pain management. Listening to music can reduce the perception of pain by distracting the client, promoting relaxation, and triggering the release of endorphins. This approach is safe, inexpensive, and can be tailored to the client’s preferences.
Correct Answer is B
Explanation
A. Administer the PN and fat emulsion separately:
Administering the PN and fat emulsion separately is not a typical practice. Usually, PN formulations are prepared to include both macronutrients (carbohydrates and fat) in a single bag to provide a balanced nutritional profile. Administering them separately might lead to inconsistencies in the client's nutritional intake.
B. Prepare the client for a central venous line:
This is the correct action. Parenteral nutrition (PN) with a high concentration of dextrose (20%) and fat emulsions can be hypertonic and irritating to peripheral veins. Therefore, a central venous line is often recommended for the administration of such solutions. Preparing the client for a central venous line helps ensure the safe and effective delivery of PN.
C. Change the PN infusion bag every 48 hr:
The frequency of changing the PN infusion bag is not solely determined by time but rather by factors such as the stability of the solution, risk of contamination, and compatibility of the components. The specific recommendation for changing the PN bag should be based on institutional policies and the characteristics of the PN solution being used.
D. Obtain a random blood glucose daily:
While monitoring blood glucose is important in clients receiving PN, obtaining a random blood glucose daily is not specific enough for managing the potential hyperglycemic effects of a 20% dextrose solution. Continuous glucose monitoring or more frequent and scheduled blood glucose checks may be necessary.
