Community Health HESI Quizlet

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: D

Rationale: In a client with diabetic ketoacidosis (DKA), urine output of 50 mL in 4 hours indicates oliguria, which is a concerning sign of decreased renal perfusion and potential renal failure. This finding requires immediate intervention to prevent further deterioration of kidney function.\n\nChoice A (Blood glucose of 200 mg/dL) is elevated but not the most urgent concern in this scenario. Choice B (Serum bicarbonate of 20 mEq/L) reflects metabolic acidosis, which is expected in DKA but does not require immediate intervention. Choice C (Blood pressure of 140/90 mm Hg) is slightly elevated but not acutely concerning in the context of DKA.

Correct Answer: D

Rationale: Using sterile technique when accessing the catheter is crucial to prevent infection in clients with a central venous catheter. This action helps maintain asepsis and reduces the risk of introducing pathogens into the catheter system. Flushing the catheter with heparin helps prevent occlusion but is not as crucial as ensuring sterile technique. Changing the dressing at the insertion site is important for assessing the site's condition but does not directly impact the administration of the antibiotic. Checking for blood return is essential to ensure proper catheter function, but sterile technique takes precedence to prevent infections.

Correct Answer: B

Rationale: The correct answer is B: higher rates of condom use among teenagers. This outcome indicates that the teenagers are adopting safer sexual practices, which can effectively reduce the incidence of STIs. Increased attendance at educational sessions (Choice A) may show interest but does not directly reflect behavior change. More teenagers seeking testing for STIs (Choice C) indicates awareness but not necessarily prevention. Greater knowledge of STI prevention methods (Choice D) is valuable but does not guarantee behavioral change like increased condom use.

Correct Answer: A

Rationale: The nurse has applied primary prevention in this situation. Primary prevention involves efforts to prevent the occurrence of domestic violence before it starts, even if the client does not admit to the abuse. Secondary prevention focuses on early detection and intervention to reduce the harm caused by violence that is already occurring. Tertiary prevention involves actions taken to rehabilitate and support individuals who have experienced domestic violence. Health promotion encompasses a broader approach aimed at improving overall health and well-being, which may include education on domestic violence prevention but is not specific to this scenario.
