A nurse is reinforcing teaching about receiving epinephrine as an emergency intervention for anaphylaxis. Which of the following information should the nurse reinforce with the client?
Epinephrine relaxes the bronchioles and counteracts the effect of histamine
Epinephrine should be given along with a beta blocker.
Epinephrine should be administered intranasally
Epinephrine causes a decrease in blood pressure
The Correct Answer is A
A. Epinephrine relaxes the bronchioles and counteracts the effect of histamine: Epinephrine is the first-line treatment for anaphylaxis because it rapidly relaxes bronchial smooth muscles, reducing airway constriction, and counteracts histamine's effects, which include vasodilation, edema, and hypotension. This helps restore breathing and circulation.
B. Epinephrine should be given along with a beta blocker: Administering epinephrine with a beta blocker is dangerous because beta blockers can reduce the effectiveness of epinephrine and may worsen bronchospasm. Beta blockers are not recommended during acute management of anaphylaxis.
C. Epinephrine should be administered intranasally: Epinephrine is typically administered intramuscularly (IM), usually into the thigh, during anaphylactic emergencies for rapid absorption. Intranasal administration is not effective for treating life-threatening systemic allergic reactions.
D. Epinephrine causes a decrease in blood pressure: Epinephrine actually increases blood pressure by causing vasoconstriction. This counters the dangerous hypotension that occurs during anaphylaxis, helping to stabilize cardiovascular function quickly.

Correct Answer is C
Explanation
A. Vitamin D: Vitamin D is a supplement used to support bone health and calcium regulation. It does not have a known adverse interaction with clopidogrel and does not increase the risk of bleeding when taken concurrently.
B. Ranitidine: Ranitidine is an H2 receptor antagonist used to reduce stomach acid. It has minimal interaction with clopidogrel and does not significantly impact bleeding risk, making it generally safe to use alongside antiplatelet therapy.
C. Naproxen: Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) that can increase the risk of gastrointestinal bleeding when used with clopidogrel, an antiplatelet agent. Combining these medications heightens the risk of serious bleeding complications and should be avoided without provider guidance.
D. Docusate sodium: Docusate sodium is a stool softener that facilitates easier bowel movements. It does not have a significant interaction with clopidogrel and does not affect bleeding risk, making it generally safe for clients requiring antiplatelet therapy.
Correct Answer is A
Explanation
A. Use a moisture barrier on the client's skin: Applying a moisture barrier cream helps protect the skin from irritation caused by constant exposure to stool and urine. It creates a protective layer that prevents breakdown, reduces friction, and maintains skin integrity in incontinent clients.
B. Clean the client's skin with soap and hot water: Using soap and hot water can strip the skin of natural oils and cause dryness or irritation, which increases the risk of breakdown. Gentle cleansing with mild soap and lukewarm water is recommended instead to preserve skin health.
C. Massage the area around the client's coccyx: Massaging bony prominences can damage fragile tissue and capillaries in older adults, increasing the risk for pressure injuries rather than preventing them. Light touch is appropriate, but firm massage should be avoided in at-risk areas.
D. Limit the client's fluid intake: Restricting fluids can lead to dehydration, concentrated urine, and an increased risk of urinary tract infections. Adequate hydration is essential to support overall health and skin resilience, even when managing incontinence.
