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?
Anaphylactic shock.
Cardiogenic shock.
Neurogenic shock.
Hypovolemic shock.
The Correct Answer is A
The correct answer is choice A: Anaphylactic shock.
Choice A rationale:
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.
Choice B rationale:
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.
Choice C rationale:
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.
Choice D rationale:
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

Correct Answer is D
Explanation
Answer is: d. Apply direct pressure above the catheterization site.
Explanation: The first action should be to apply direct pressure above the catheterization site to help control the bleeding and minimize blood loss. This will also give the nurse time to prepare additional interventions or supplies if necessary.
Choice a. is wrong because placing the child in the Trendelenburg position is not an appropriate initial nursing action in this scenario. This position can increase intracranial pressure and is typically used for patients experiencing shock or hypotension.
Choice b. is wrong because applying a new bandage with more pressure might be a subsequent action, but the priority is to apply direct pressure to slow down the bleeding.
Choice c. is wrong because notifying the physician is important, but the nurse should first take immediate action to control the bleeding and minimize potential harm to the patient.
Correct Answer is A
Explanation
The correct answer is choice A. Potassium.
Choice A rationale:
Diuretics like furosemide are commonly used to treat congestive heart failure. They work by increasing the excretion of water and electrolytes, including potassium, from the body. Low levels of potassium (hypokalemia) can lead to various complications, including cardiac arrhythmias and muscle weakness. Since furosemide can cause potassium loss, it's important to ensure an adequate intake of potassium-rich foods. Bananas, oranges, and leafy vegetables are excellent sources of potassium. Therefore, the nurse encourages the family to include these foods in the child's diet to help maintain a healthy potassium balance.
Choice B rationale:
Sodium is an important electrolyte, but in the context of congestive heart failure and diuretic use, the focus is more on avoiding excessive sodium intake. Diuretics like furosemide aim to reduce fluid retention by increasing sodium excretion, so it's not necessary to recommend high-sodium foods. Moreover, excessive sodium intake could exacerbate fluid retention and worsen the heart failure.
Choice C rationale:
Chlorides are often found in table salt (sodium chloride) and are not typically emphasized in the context of heart failure treatment or diuretic use. While they play a role in maintaining electrolyte balance, they are not the primary focus in this scenario.
Choice D rationale:
Zinc is a mineral that is not directly related to the treatment of congestive heart failure or the use of diuretics. It is important for various cellular functions and immune system support, but it's not the electrolyte of concern in this situation.
