A nurse is teaching a client about reducing the risk for osteoporosis. Which of the following statements by the client indicates an understanding of possible anaphylaxis?

A. A feeling of swelling in the feet: Swelling in the feet can be caused by various factors such as fluid retention, circulatory issues, or certain medical conditions like venous insufficiency. It is not a typical symptom of anaphylaxis, which usually involves more generalized symptoms such as hives, itching, swelling of the face or throat, difficulty breathing, and a drop in blood pressure.

B. Pain at the injection site: Pain at the injection site is a common side effect of receiving an injection or medication. It occurs due to tissue irritation or trauma from the needle. While allergic reactions can cause localized redness, swelling, or itching at the injection site, severe pain alone is not a hallmark symptom of anaphylaxis.

C. A sudden decrease in heart rate: Anaphylaxis typically leads to an increase in heart rate (tachycardia) rather than a decrease. This increase in heart rate is a response to the body's attempt to compensate for the drop in blood pressure caused by anaphylaxis. Bradycardia (a decrease in heart rate) is not a typical feature of anaphylaxis unless it occurs very late in a severe reaction due to profound circulatory collapse.

D. A sharp decrease in blood pressure: This choice is indicative of an understanding of possible anaphylaxis. Anaphylaxis can cause a rapid and severe drop in blood pressure, known as hypotension. This drop in blood pressure is often a key feature of anaphylaxis and can lead to symptoms such as dizziness, fainting, confusion, and shock.

A. Assault.

Assault is the threat or apprehension of harmful or offensive contact. In this scenario, the nurse is making a threat to administer medication by injection if the client doesn't comply with swallowing pills. Even though the nurse hasn't physically carried out the action yet, the threat itself constitutes assault. The client feels threatened by the nurse's statement, creating apprehension of harm or offensive contact.

B. Defamation: Defamation involves making false statements that harm a person's reputation. There is no indication of defamation in this scenario.

C. Battery: Battery involves the intentional and unauthorized touching of another person. While administering medication by injection without consent could be considered battery, the nurse has only made a threat at this point, not carried out the action.

D. Invasion of privacy: Invasion of privacy involves intruding into someone's private affairs without permission. There is no indication of invasion of privacy in this scenario.
