Correct Answer: D

Rationale: The correct answer is D: Consumption of contaminated food. Hepatitis A is primarily transmitted through the ingestion of contaminated food or water. Airborne droplets and sexual contact are not common modes of transmission for hepatitis A. While contact with contaminated surfaces can play a role in the spread of some infections, hepatitis A is not typically transmitted through this route.

Correct Answer: B

Rationale: The correct answer is B: 'Limit fluid intake to 1-2 liters per day.' For clients with heart failure, fluid restriction is essential to prevent fluid overload. Restricting fluid intake to 1-2 liters per day helps maintain fluid balance and prevents exacerbation of heart failure symptoms. Choices A, C, and D are incorrect because consuming 3 liters, 4 liters, or limiting water intake to 1 liter per day, respectively, can lead to fluid overload in clients with heart failure.

Correct Answer: A

Rationale: The correct answer is A. Low blood sugar levels (50 mg/dL) typically cause confusion, cold clammy skin, and an increased pulse (tachycardia). Option A correctly describes the expected symptoms of hypoglycemia, which include confusion due to the brain's inadequate glucose supply, cold and clammy skin due to sympathetic nervous system activation, and an increased pulse (110 bpm) as the body reacts to low blood sugar levels. Options B, C, and D describe symptoms that are not typically associated with hypoglycemia. Lethargy, hot dry skin, rapid deep respirations, normal vital signs, shortness of breath, distended neck veins, and bounding pulse are more indicative of other conditions or normal physiological responses, not hypoglycemia.

Correct Answer: B

Rationale: The correct answer is B because avoiding perfumed lotions is important to prevent skin irritation after radiation therapy. Using a heating pad (A) can further damage the skin, applying cold compresses (C) may not be recommended, and scrubbing the area daily with soap and water (D) can be too harsh on the skin, leading to further irritation and damage.

Correct Answer: B

Rationale: The correct answer is B: Ensure that oxygen tanks are kept upright and away from heat sources. This is the most important safety measure to prevent accidents related to home oxygen use. Storing oxygen tanks in a closet when not in use (choice A) is not recommended as they should be stored in a well-ventilated area. Allowing family members to smoke in designated areas (choice C) poses a significant fire hazard. Restricting fluid intake while using oxygen (choice D) is not a safety measure related to oxygen use.
