A client comes to the emergency department following a bee sting. The client has a diffuse. rash, hypotension, and throat tightness. One injection of IM epinephrine does not improve the client's condition. What action should the nurse take next?
Anaphylactic shock has an acute onset, and manifestations usually develop quickly (20- 30 minutes). Circulatory failure and respiratory manifestations, including laryngeal edema (from inflammation) and bronchoconstriction (primarily from release of histamine), can lead to cardiac/respiratory arrest.
The management of anaphylactic shock includes:
- Ensure patent airway, administer oxygen
- Remove insect stinger if present
- IM epinephrine is the drug of choice and should be given to this client. Epinephrine stimulates both alpha- and beta-adrenergic receptors and dilates bronchial smooth muscle (beta 2) and provides vasoconstriction (alpha 1). The IM route (mid anterior lateral thigh) is better than the subcutaneous route. Repeat dose every 5-15 minutes.
- Place in recumbent position and elevate legs
- Maintain blood pressure with IV fluids, volume expanders or vasopressors
- Bronchodilator (inhaled beta agonist) such as albuterol is administered to dilate the small airways and reverse bronchoconstriction
- Antihistamine (diphenhydramine) is administered to modify the hypersensitivity reaction and relieve pruritus
- Corticosteroids (methylprednisolone [Solu-Medrol]) are administered to decrease airway inflammation and swelling associated with the allergic reaction
- Anticipate cricothyrotomy or tracheostomy with severe laryngeal edema
(Option 1, 2, and 3) These are appropriate responses that should come after a repeat dose of epinephrine has been given.
Educational objective:
- IM epinephrine is the single most important medication to be given in anaphylactic shock.
- The dose should be repeated every 5-15 minutes if symptoms are still present.

Rules differ from country to country, so make sure you’re of the
legal gambling age and follow your local laws before you play.
Remember, online gambling laws are different in each region Show more No matter where you
play, just remember to focus on having fun and always practice responsible gambling.
All the top Australian casino sites
we recommend meet these standards, making it easy for you.
Whether you’re chasing bonuses, climbing tournament leaderboards, or just looking for
a fun, fast-paced way to play online casino games, the sites we’ve featured deliver.
Whether you’re new to real money casino games or trying out esports betting, here
are a few quick tips to help you play smarter and (ideally) win more often at the best online casino sites.
Australian online casinos offer welcome bonuses, deposit bonus, free spins, loyalty rewards,
and some sort of cashback on losses. The newest online casinos for Australian players aren’t just pokies platforms anymore — they’re full-scale gaming libraries designed
for every kind of player.
You shouldn’t settle for Australian online casino sites that need 3 days to approve a payout request.
Wagering requirements must be within industry limits, the
bonuses should be accessible to all players, and the expiry dates
should be reasonable. I’m personally not a big
fan of these, to be honest, but the number of players logging bets onto them at every casino website says they are nearly as popular as table games.
