Staff must report if a resident consumes less than _______ of his meal.

Correct Answer: B

Rationale: The correct answer is B (50%). Staff must report if a resident consumes less than 50% of his meal as this indicates a significant decrease in food intake which could impact the resident's health. Reporting at 75% (Choice A) may be too lenient and miss early signs of decreased appetite. Reporting at 35% (Choice C) may be too strict and result in unnecessary reporting for minor fluctuations. Reporting at 80% (Choice D) may not capture instances where the resident is not consuming enough food for proper nutrition. Therefore, 50% is the most appropriate threshold for reporting.

Correct Answer: D

Rationale: The correct answer is D: Endometrial cancer. This form of cancer starts in the lining of the uterus, called the endometrium. Cervical cancer (A) originates in the cervix, ovarian cancer (B) in the ovaries, and testicular cancer (C) in the testicles. By process of elimination, endometrial cancer is the only choice that correctly matches the description of cancer beginning in the uterus.

Correct Answer: B

Rationale: The correct answer is B: Increasing iron intake. Iron is essential for the production of hemoglobin, which carries oxygen in red blood cells. Anemia is often due to an iron deficiency, so increasing iron intake helps replenish iron stores and improve red blood cell production. Reducing vitamin intake (A) is not recommended as vitamins play a crucial role in overall health. Injections of vitamin K (C) are not typically used to treat anemia. Decreasing fiber in the diet (D) is unrelated to anemia and can even worsen the condition by limiting nutrient absorption.

Correct Answer: B

Rationale: The correct answer is B: Pad the edge of the cast to reduce sharp edges. This is important to prevent skin irritation and injury from the rough edges of the cast. By padding the edges, it helps to distribute pressure evenly and decrease the risk of abrasions. Choice A is incorrect because using a sharp scratcher inside the cast can lead to skin damage and infections. Choice C is incorrect as keeping the cast damp or wet can cause skin maceration and increase the risk of infection. Choice D is incorrect as keeping the extremity low close to the ground can lead to swelling and discomfort.

Correct Answer: C

Rationale: The correct answer is C: Hyperthyroidism. Hyperthyroidism is when the thyroid gland produces an excess of thyroid hormone, leading to symptoms like weight loss, rapid heartbeat, and anxiety. Hypothyroidism (A) is the opposite, where the thyroid gland produces too little hormone. Hypertension (B) is high blood pressure and is not directly related to thyroid function. Hypothermia (D) is a condition of abnormally low body temperature and is not caused by thyroid hormone imbalance. In this case, the symptoms described align with hyperthyroidism, making it the correct answer.
