A child is brought to the emergency department experiencing an anaphylactic reaction to a bee sting. While an airway is being established, what medication should the nurse prepare for immediate administration?
A. Diphenhydramine.
Diphenhydramine. Diphenhydramine is an antihistamine commonly used to relieve allergic symptoms such as itching, rash, and runny nose. While it can be part of the treatment for anaphylactic reactions, it is not the medication of choice for immediate administration in the case of a severe anaphylactic reaction like the one described in the scenario.
B. Epinephrine.
Epinephrine. Correct Answer. In cases of severe anaphylactic reactions, epinephrine (adrenaline) is the medication of choice for immediate administration. Epinephrine acts rapidly to reverse life-threatening symptoms, such as airway constriction, low blood pressure, and hives. It works by dilating airways, increasing heart rate, and improving blood pressure.
C. Dopamine.
Dopamine. Dopamine is a medication used to increase blood pressure and cardiac output in certain critical situations. However, it is not the first-line treatment for anaphylactic reactions. Epinephrine's effects on airway and cardiovascular function make it the preferred choice in this context.
D. Calcium chloride.
Calcium chloride. Calcium chloride is not the appropriate medication for treating anaphylactic reactions. Its main medical uses include treating hypocalcemia (low blood calcium levels) and certain cardiac arrhythmias. It does not address the primary symptoms and physiological changes associated with anaphylaxis.

Full Explanation
The correct answer is choice B. Epinephrine.
Choice A rationale:
Diphenhydramine. Diphenhydramine is an antihistamine commonly used to relieve allergic symptoms such as itching, rash, and runny nose.

Epinephrine acts rapidly to reverse life-threatening symptoms, such as airway constriction, low blood pressure, and hives. It works by dilating airways, increasing heart rate, and improving blood pressure.
Choice C rationale:
Dopamine. Dopamine is a medication used to increase blood pressure and cardiac output in certain critical situations. However, it is not the first-line treatment for anaphylactic reactions. Epinephrine's effects on airway and cardiovascular function make it the preferred choice in this context.

Similar Questions
When providing education on Tinea capitis, what information should the nurse include?
A. Central clearing is a prominent indicator of this condition.
Central clearing is not a prominent indicator of Tinea capitis. Tinea capitis is a fungal infection of the scalp and hair shafts, commonly caused by dermatophytes like Trichophyton species. The characteristic features include scaling, erythema, pustules, and hair loss. Unlike some other fungal infections, Tinea capitis does not typically have central clearing.
B. Lesions may extend to hairline or neck.
Lesions extending to the hairline or neck is a correct aspect to include in education about Tinea capitis. The infection usually starts as small, scaly patches on the scalp and can progress to larger areas. It can extend to the hairline, neck, and even eyebrows and eyelashes. This is important information to convey to ensure proper recognition and timely treatment.
C. Transmission mostly occurs from dogs.
Transmission of Tinea capitis mostly occurs from human-to-human rather than from dogs. While some animals can carry fungal infections that affect the skin, Tinea capitis is primarily spread through direct contact with an infected person or contaminated objects like combs, hats, and pillows.
D. Appearance is usually unilateral.
The appearance of Tinea capitis is not usually unilateral. This condition often presents with multiple, scattered areas of involvement on the scalp. It can cause varying degrees of inflammation, scaling, and hair loss in different areas, which may not follow a unilateral pattern.

What is a common side effect of corticosteroid therapy?
A. Increased appetite.
Increased appetite is a common side effect of corticosteroid therapy. Corticosteroids are known to affect various metabolic processes, and one of the effects is an increase in appetite. This can lead to weight gain, especially when the increased calorie intake is not balanced by physical activity.
B. Fever.
Fever is not a typical side effect of corticosteroid therapy. Corticosteroids are often used to reduce inflammation and suppress the immune response, which can help in managing conditions like autoimmune diseases, allergies, and inflammatory disorders. Fever is not a direct result of corticosteroid administration.
C. Weight loss.
Weight loss is not a common side effect of corticosteroid therapy. In fact, corticosteroids are more likely to cause weight gain due to their influence on appetite, metabolism, and fluid retention.
D. Hypertension.
Hypertension (high blood pressure) can indeed be a side effect of corticosteroid therapy. Corticosteroids can lead to sodium and water retention, which can contribute to increased blood pressure, particularly in individuals who are already at risk for hypertension. However, among the options provided, increased appetite is a more directly associated side effect of corticosteroid therapy.

What type of shock is characterized by a hypersensitivity reaction causing massive vasodilation and capillary leaks, which may occur with a drug or latex allergy?
A. Anaphylactic shock.
Anaphylactic shock is the correct answer. Anaphylactic shock is a severe and potentially life-threatening allergic reaction that causes massive vasodilation, capillary leakage, and bronchoconstriction. It can occur rapidly after exposure to an allergen such as certain foods, insect stings, medications, or latex. The release of histamine and other inflammatory mediators leads to systemic vasodilation and increased permeability of blood vessels, resulting in a sudden drop in blood pressure and compromised organ perfusion.
B. Cardiogenic shock.
Cardiogenic shock is characterized by inadequate cardiac output due to severe heart dysfunction. It is typically caused by conditions like myocardial infarction, heart failure, or other cardiac issues. While allergic reactions can potentially affect the cardiovascular system, the symptoms described in the question are more indicative of anaphylactic shock.
C. Neurogenic shock.
Neurogenic shock results from disruption of sympathetic nervous system control over blood vessel tone, often due to spinal cord injury or severe emotional distress. This leads to widespread vasodilation and a sudden drop in blood pressure. While it can cause hemodynamic instability, it doesn't specifically involve the hypersensitivity reaction and capillary leaks associated with anaphylactic shock.
D. Hypovolemic shock.
Hypovolemic shock is caused by a significant loss of blood volume or bodily fluids, leading to decreased intravascular volume and subsequent inadequate tissue perfusion. This shock type is not directly related to a hypersensitivity reaction or capillary leakage caused by allergic responses. 2 / 2
