Community Health HESI Quizlet

Correct Answer: A

Rationale: The correct answer is A: Infection is acquired when anthrax spores enter a host. Anthrax is primarily transmitted through spores entering the body, either through the skin, inhalation, or ingestion. Person-to-person transmission of anthrax is extremely rare and not a significant mode of transmission. Choices B and C are incorrect because mature anthrax bacteria do not live dormant on inanimate objects, and spores can survive for extended periods outside a living host. Choice D is incorrect as anthrax is not transmitted by respiratory droplets from person to person.

Correct Answer: C

Rationale: The slightly yellow color of the sclera is a normal racial variation found in the African-American population. Blue sclerae (Choice A) are associated with osteogenesis imperfecta, not a normal racial variation. Brown macules on the sclerae (Choice B) may indicate issues like melanoma or melanosis but are not a normal racial variation. Conjunctival pallor (Choice D) suggests anemia or decreased blood flow but is not a normal racial variation.

Correct Answer: C

Rationale: A temperature of 99�F (37.2�C) in a postoperative client requires immediate intervention as it may indicate the presence of infection. Elevated temperature post-surgery can be a sign of surgical site infection or systemic infection, which can lead to serious complications if not addressed promptly. Monitoring and managing a fever in a postoperative client is crucial to prevent further complications. The other findings, such as a heart rate of 90 beats per minute, oxygen saturation of 92%, and pain at the surgical site, are common postoperative assessments that may not necessarily require immediate intervention unless they are significantly out of normal range or causing severe distress to the client.

Correct Answer: C

Rationale: The correct intervention for a client with a platelet count of 20,000/mm3 due to chemotherapy is to avoid invasive procedures. Chemotherapy can cause a decrease in platelet count, leading to an increased risk of bleeding. By avoiding invasive procedures, the nurse helps reduce the risk of bleeding complications. Applying ice packs to bruised areas (Choice A) may further increase the risk of bleeding due to the pressure and potential trauma to the skin. Encouraging frequent oral hygiene (Choice B) is important for overall health but does not directly address the risk of bleeding associated with a low platelet count. Placing the client in a private room (Choice D) is not directly related to managing the platelet count and risk of bleeding; it is more about privacy and infection control, which are important but not the priority in this scenario.

Correct Answer: D

Rationale: The drainage of clear, pale yellow fluid from the chest tube is an indication of proper chest tube functioning. Clear, pale yellow fluid signifies normal drainage from the pleural space without any signs of infection or complications. Choices A, B, and C are incorrect because continuous bubbling in the water-seal chamber, no fluctuation in the water-seal chamber, and intermittent bubbling in the suction control chamber are all indications of potential issues or malfunctioning of the chest tube system, which would require further assessment and intervention.
