Correct Answer: C

Rationale: In a situation where a patient is experiencing anaphylaxis, it is crucial to act swiftly. Asking the woman if she carries an emergency medical kit is the most appropriate initial intervention. Many individuals with a history of anaphylaxis carry epinephrine auto-injectors, such as epi-pens, which can be life-saving in such situations. Initiating cardiopulmonary resuscitation (CPR) is not indicated as the patient is breathing but short of breath, and CPR is not the first-line intervention for anaphylaxis. Checking for a pulse, though important, is not the initial priority in managing anaphylaxis. Staying with the woman until help arrives is essential for providing support and monitoring her condition, but confirming the availability of an emergency medical kit takes precedence to promptly address the anaphylactic reaction.

Correct Answer: A

Rationale: For a child of this age, this is adequate output, yet does not suggest overload. Disruption of sodium-ATPase activity presumably causes an intracellular sodium shift which contributes to hypovolemia and cellular edema. Heat injury also initiates the release of inflammatory and vasoactive mediators. These mediators are responsible for local vasoconstriction, systemic vasodilation, and increased transcapillary permeability. Increase in transcapillary permeability results in a rapid transfer of water, inorganic solutes, and plasma proteins between the intravascular and interstitial spaces.

Correct Answer: A

Rationale: The correct answer is 'Fever and rash.' Rocky Mountain Spotted Fever (RMSP) is caused by the R. rickettsii pathogen, which damages blood vessels. Patients with RMSP typically present with fever, edema, and a rash that initially appears on the hands and feet before spreading across the body. The disease manifests following a tick bite. Choice A is correct as fever and rash are key indicators of RMSP. Circumoral cyanosis (choice B) is not typically associated with RMSP; it refers to a bluish discoloration around the mouth and is more indicative of oxygen deprivation. Elevated glucose levels (choice C) are not specific signs of RMSP. Therefore, choice D, 'All of the above,' is incorrect since only choice A, 'Fever and rash,' is associated with Rocky Mountain Spotted Fever.

Correct Answer: C

Rationale: The correct answer is to administer prescribed opioids to relieve pain as needed. Pain management is the highest priority in this scenario as effective pain control is essential for the patient's overall well-being. Pain relief will not only improve the patient's comfort but also enhance their ability to eat, follow dietary recommendations, and be open to psychological support. Offering psychological support for depression (Choice A) is important but addressing pain takes precedence. While providing high-calorie, high-protein dietary choices (Choice B) is crucial, it is secondary to managing pain. Teaching about the need to avoid scratching pruritic areas (Choice D) is relevant but not the highest priority in this situation where pain management is critical for the patient's quality of life.

Correct Answer: A

Rationale: The child's refusal to walk, along with swelling of the lower leg, indicates a possible fracture, specifically of the tibia. Fractures can cause pain and swelling, leading to difficulty or refusal to bear weight on the affected limb. Choice B, bruising of the gastrocnemius muscle, would not typically result in the child refusing to walk. Choice C, a possible fracture of the radius, is less likely given the location of the swelling and the associated refusal to walk. Choice D, stating no anatomic injury and attributing the child's behavior to wanting to be carried by the mother, is incorrect as the physical findings suggest a potential fracture that needs to be evaluated further.
