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 D
Explanation
A. WBC count 12,000/mm³: A mild elevation in white blood cell count is expected within the first few days postpartum as part of the normal inflammatory response due to the stress of labor and delivery.. A count of 12,000/mm³ is not alarming and does not necessarily indicate infection or a complication.
B. Temperature 37.8°C (100°F): A low-grade temperature elevation within the first 24 hours postpartum is common due to hormonal shifts, dehydration, or exertion from labor. This finding would not immediately require provider notification unless it persists or rises higher.
C. Respiratory rate 16/min: A respiratory rate of 16 breaths per minute is within normal adult limits and does not suggest respiratory distress or any postpartum complication, so no intervention is required for this finding.
D. Hgb 8 g/dL: A hemoglobin level of 8 g/dL is significantly low and can indicate postpartum hemorrhage or significant blood loss. This degree of anemia should be reported promptly to the provider to assess the need for interventions such as blood transfusion or iron supplementation.
Correct Answer is A
Explanation
A. Ask the client's family about cultural or religious practices regarding postmortem care: Respecting the client's and family's cultural and religious preferences is an important aspect of providing dignified and individualized postmortem care. Some practices may have specific rituals that should be honored.
B. Remove the client's dentures from their mouth before rigor mortis begins: Dentures are usually placed back into the client's mouth, not removed, to maintain a natural facial appearance and support the facial structure before rigor mortis sets in.
C. Turn on all the lights in the room before the family views the client's body: Creating a calm, peaceful environment is preferred when the family views the body. Harsh lighting may feel overwhelming or intrusive during such an emotional time.
D. Position the client's bed flat without a pillow under their head: Elevating the head of the bed slightly and placing a pillow under the head can help prevent blood from pooling in the head and face, preserving a more natural appearance. Leaving the bed flat is not ideal.
