Which of the following statements about mealtime is true?

Correct Answer: A

Rationale: The correct answer is A because social interaction plays a crucial role in mealtime, enhancing residents' overall dining experience and well-being. Engaging in conversations and fostering connections during meals can promote a sense of community, reduce isolation, and improve residents' emotional and mental health. Choice B is incorrect because it promotes dependence and undermines residents' independence and dignity. Nursing assistants should support residents in mealtime activities while encouraging their autonomy. Choice C is incorrect as it prioritizes personal conversations over residents' needs and fails to recognize the importance of providing individualized care during mealtimes. Choice D is incorrect because it may negatively impact residents' dining experience by potentially discouraging them from eating. Instead, nursing assistants should offer support and alternatives if meals are unappetizing while respecting residents' choices.

Correct Answer: D

Rationale: The correct answer is D because contact of the mouth with the genitals can directly transmit sexually transmitted infections (STIs) through mucous membranes. Mouth-to-mouth kissing (A) and holding hands (C) do not involve direct contact with genitalia, making transmission of STIs unlikely. Contact of hands with the breasts (B) also does not typically transmit STIs as they are not mucous membranes. Therefore, D is the correct choice for STI transmission via sexual contact.

Correct Answer: C

Rationale: The correct answer is C: Plasma. Plasma constitutes about 55% of blood volume and is a fluid component that carries various substances such as nutrients, hormones, and waste products. Erythrocytes (A) are red blood cells and make up about 40-45% of blood volume. Leukocytes (B) are white blood cells and only account for a small percentage of blood volume. Platelets (D) are cell fragments involved in blood clotting and make up a very small percentage of blood volume. Plasma is the correct answer because it is the largest component of blood by volume and carries out essential functions in the body.

Correct Answer: A

Rationale: The correct answer is A because normal age-related changes in the musculoskeletal system typically involve muscles weakening and losing tone. This is due to factors such as decreased physical activity, hormonal changes, and reduced muscle mass. Choice B is incorrect because while bones do require calcium for strength and density, age-related changes typically involve bone loss rather than gain. Choice C is incorrect as muscle mass tends to decrease with age, not increase. Choice D is incorrect as age-related changes in the musculoskeletal system do not directly cause weight gain, although decreased muscle mass and physical activity can contribute to weight gain.

Correct Answer: C

Rationale: The correct answer is C: Medication or surgery. Seizures are caused by abnormal electrical activity in the brain, and treatment usually involves medication to control or prevent seizures. Surgery may also be an option for some cases, such as when medication is not effective or when there is a specific brain abnormality causing the seizures. Range of motion exercises (A), restraining the resident (B), and physical therapy (D) are not appropriate treatments for seizures as they do not address the underlying neurological cause.
