The mother of a 2-year-old is concerned because her son has had three ear infections in the past year. Which of the following would be an appropriate response by the nurse?

Correct Answer: D

Rationale: The correct answer is D because it provides an accurate explanation for the frequent ear infections in the 2-year-old. The eustachian tube in children is indeed shorter and wider compared to adults, making it easier for infections to develop. This anatomical difference predisposes young children to ear infections. Choice A is incorrect because it falsely implies that frequent ear infections in small children are unusual only if something else is wrong. Choice B is incorrect as checking the immune system is not typically the first step in addressing recurrent ear infections. Choice C is incorrect as cerumen (earwax) does not directly contribute to ear infections in the middle ear.

Correct Answer: C

Rationale: Step 1: Down's syndrome is associated with characteristic physical features. Step 2: One common physical feature is a protruding tongue due to a small oral cavity. Step 3: This is known as macroglossia and is seen in individuals with Down's syndrome. Step 4: Therefore, the nurse looks for a protruding thin tongue in children with Down's syndrome. Summary: A is incorrect because ear dysplasia is not a common feature. B is incorrect as a long, thin neck is not a typical characteristic. D is incorrect because a narrow and raised nasal bridge is not a key feature of Down's syndrome.

Correct Answer: C

Rationale: Rationale for Correct Answer (C): 1. Immediate intervention is crucial as the newborn needs clear airways for breathing. 2. Inability to suction the nares can lead to respiratory distress and compromise the infant's oxygenation. 3. Waiting or attempting again may delay necessary actions, risking the baby's health. 4. Physician's assistance may be needed, but recognizing the urgency is the nurse's responsibility to ensure timely care. Summary of Incorrect Choices: A. Attempting to suction again with a bulb syringe may not resolve the issue and delay necessary intervention. B. Waiting for the infant to stop crying is not ideal as it may prolong the risk of respiratory distress. D. While physician assistance may be necessary, immediate recognition of the critical situation is the nurse's primary responsibility.

Correct Answer: D

Rationale: The signs and symptoms - severe headache, high fever, and neck stiffness - in a young adult point towards meningeal inflammation. The combination of these symptoms is indicative of a potential infection or inflammation of the meninges, the protective membranes surrounding the brain and spinal cord. The presence of fever and neck stiffness, in addition to the severe headache, raises concern for meningitis, an infection of the meninges. This is a medical emergency that requires prompt evaluation and treatment. Other choices are incorrect because: A: Head injury usually presents with a history of trauma, which is not mentioned in the scenario. B: Cluster headaches typically do not present with fever and neck stiffness. C: Migraine headaches do not typically cause such high fever and neck stiffness.

Correct Answer: A

Rationale: The correct answer is A: thyroid gland. Thyroxine is a hormone produced by the thyroid gland. An elevated thyroxine level indicates a potential thyroid gland dysfunction. The nurse would examine the thyroid gland to assess its size, texture, and any signs of abnormalities. Incorrect choices: B: Parotid gland - This gland is responsible for producing saliva, not thyroxine. C: Adrenal gland - Responsible for producing hormones like cortisol and adrenaline, not thyroxine. D: Thyroxine gland - There is no such thing as a "thyroxine gland." Thyroxine is a hormone produced by the thyroid gland.
