Correct Answer: D

Rationale: In this scenario, the mother, who is 35 years old and illiterate but with on and off seizure, is the best candidate to sign the informed consent for a surgical procedure for the child. The mother is the primary caregiver and decision-maker for the child in most cases, and her relationship to the child is most crucial in this situation. Despite her illiteracy, she can still comprehend the importance of the procedure for her child's well-being. Additionally, accommodations can be made for an illiterate person to sign the consent form by using an "X" as a signature. It is important that the person signing the consent form has a clear understanding of the risks and benefits involved, as well as the ability to make decisions in the best interest of the child.

Correct Answer: B

Rationale: The statement that the preschooler can alternate feet when climbing is not true. Typically, preschoolers at this age group are still developing their coordination and may not have mastered the skill of alternating feet while climbing. It is more common for them to use one foot after the other while climbing. This skill usually requires more advanced motor development and coordination, which may come later in the preschool years.

Correct Answer: C

Rationale: The presentation described is most consistent with a thyroid adenoma. Thyroid adenomas are benign neoplasms of the thyroid gland and can present as painless, gradually enlarging masses in the neck. Fine-needle aspiration cytology revealing thyroid follicular cells further supports the diagnosis of a thyroid adenoma. Thyroglossal duct cysts typically present as midline neck masses that move with swallowing, while lymphadenopathy presents as enlarged lymph nodes and may be associated with infection or malignancy. Thyroid carcinoma may also present as a neck mass but is more likely to be associated with other features such as vocal cord paralysis, hoarseness, or enlarged cervical lymph nodes.

Correct Answer: C

Rationale: In response to chronic hypoxia, the body adapts to increase oxygen delivery to tissues by increasing cardiac output. This is achieved by increasing the heart rate and stroke volume, allowing more oxygenated blood to be pumped to the tissues. The increased cardiac output helps compensate for the lower oxygen levels in the blood, ensuring that tissues receive an adequate supply of oxygen despite the hypoxic conditions. This physiological adaptation is essential for maintaining tissue oxygenation and supporting overall cellular function in the presence of chronic hypoxia.

Correct Answer: A

Rationale: In a patient with severe abdominal pain due to end-stage pancreatic cancer, the priority intervention to manage their symptoms would be to provide adequate pain relief. Opioid analgesics are the cornerstone of pain management for cancer patients experiencing severe pain. They work by binding to opioid receptors in the central nervous system, thereby reducing the perception of pain. Opioids are highly effective in managing cancer pain, including abdominal pain, and can significantly improve the patient's quality of life by providing relief from distressing symptoms. Therefore, administering opioid analgesics should be the nurse's primary intervention in this case to address the patient's severe abdominal pain. Initiating enteral nutrition, recommending hot compresses, or referring to a gastroenterologist may be relevant interventions depending on the patient's overall care plan but addressing the pain should be the immediate priority in this scenario.
