Correct Answer: C

Rationale: During a thoracic examination, normal findings should include resonance, which is the expected sound when percussing the thorax. Resonance indicates healthy lung tissue and air-filled spaces. Abnormal findings such as rhonchi and crackles suggest issues like lung congestion or inflammation. Tactile fremitus refers to vibrations felt on the chest wall during palpation and is not typically assessed during percussion and auscultation of the thorax.

Correct Answer: A

Rationale: The correct answer is A: Formula or breast milk. In infants with gastroenteritis and mild dehydration, it is essential to continue feeding them with formula or breast milk along with oral rehydration fluids to provide adequate nutrition and maintain hydration. Option B, broth and tea, may not provide the necessary nutrients and electrolytes needed for the infant's recovery. Option C, rice cereal and apple juice, can be harsh on the digestive system and may exacerbate diarrhea. Option D, gelatin and ginger ale, do not provide the necessary nutrients and can worsen the condition due to the high sugar content in ginger ale.

Correct Answer: A

Rationale: The correct answer is weight gain. In hypothyroidism, there is a decrease in metabolic rate, which can lead to weight gain. Heat intolerance (choice B) is more commonly associated with hyperthyroidism. Increased appetite (choice C) and frequent diarrhea (choice D) are not typical findings in hypothyroidism. Therefore, choices B, C, and D are incorrect.

Correct Answer: D

Rationale: The correct answer is the oral cavity. During cancer treatment involving radiation to the head and intravenous chemotherapy, the oral cavity is a priority assessment area. Radiation can reduce salivary flow and lower the pH of saliva, which can lead to stomatitis and tooth decay. Assessing the oral cavity allows for the early identification and management of potential complications. Choice A, assessing the feet, is not the priority in this scenario as it is not directly impacted by the described cancer treatments. Choice B, assessing the nail beds, is not the priority compared to the oral cavity. Nail bed assessment may be relevant for certain conditions, but in this case, the oral cavity is of higher priority due to the specific treatment effects. Choice C, assessing the perineum, is also not the priority in this situation as it is not directly affected by the described cancer treatments, unlike the oral cavity.

Correct Answer: A

Rationale: Urticaria, also known as hives, is a common manifestation of a mild allergic reaction. It presents as raised, red, itchy welts on the skin. Ptosis is drooping of the upper eyelid and is not typically associated with allergic reactions. Nausea is a gastrointestinal symptom that can occur with various conditions but is not specific to allergic reactions. Hematuria, which is the presence of blood in the urine, is not a typical manifestation of an allergic reaction.
