Correct Answer: A

Rationale: During a routine health screening for a 1-year-old child, the most critical topic for the nurse to discuss with the parents is the potential hazards of accidents. Accidents are the primary source of injury in children and can be life-threatening. Discussions about appropriate nutrition should have been addressed during the weaning process, while the purchase of appropriate shoes is important but not life-threatening. Toilet training typically begins around 2 years of age, so 1 year of age is too early to discuss it. Therefore, the focus should be on educating parents about accident prevention to ensure the child's safety and well-being.

Correct Answer: B

Rationale: Acetaminophen is extensively metabolized in the liver. An overdose of acetaminophen can lead to severe liver damage and even liver failure, which can be life-threatening. Choices A, C, and D are incorrect because although prolonged use of acetaminophen may lead to an increased risk of renal dysfunction, a single overdose does not typically cause life-threatening abnormalities in the lungs, kidneys, or adrenal glands.

Correct Answer: D

Rationale: Scurvy is indeed associated with inadequate intake of vitamin C. Vitamin C deficiency leads to scurvy, which is characterized by weakness, anemia, gum disease, and skin hemorrhages. Choices A, B, and C are incorrect because rickets is caused by vitamin D deficiency, marasmus is due to severe malnutrition leading to wasting, and kwashiorkor is a form of severe protein-energy malnutrition.

Correct Answer: B

Rationale: The correct answer is 'eggs.' Eggs are considered a complete protein as they contain all nine essential amino acids required by the body. On the other hand, corn, peanuts, and sunflower seeds are incomplete proteins, meaning they lack one or more of the essential amino acids needed by the body for optimal health. Corn, peanuts, and sunflower seeds are plant-based proteins that are deficient in one or more essential amino acids, unlike eggs, which are a high-quality complete protein source.

Correct Answer: D

Rationale: When considering hormone replacement therapy for a menopausal woman, unexplained vaginal bleeding should be recognized as a contraindication. This is because it could be indicative of a serious underlying condition that needs investigation before initiating hormone therapy. A family history of stroke, by itself, is not a contraindication for hormone replacement therapy, unless the woman herself has a history of stroke or blood-clotting events. Ovaries removed before age 45 may actually increase the likelihood of needing hormone replacement therapy due to early menopause. Frequent hot flashes and night sweats, on the other hand, are symptoms that can be relieved by hormone replacement therapy, making them a potential indication rather than a contraindication.
