The nurse is assessing a 3-year-old who has been brought to the clinic for"drainage from the nose." On assessment, it is found that there is a purulent, malodorous drainage from the left naris but no drainage from the right naris. The child is afebrile and has no other symptoms. What should the nurse do next?

Correct Answer: C

Rationale: The correct answer is C: Perform an otoscopic examination of the left naris. The rationale for this is that the child presenting with purulent, malodorous drainage from one naris may indicate a foreign body lodged in the left naris causing infection. By performing an otoscopic examination, the nurse can visualize inside the naris to identify any foreign body or signs of infection. This step is crucial for determining the appropriate treatment plan. Choices A, B, and D are incorrect: A: Referring the child for an antibiotic prescription without further assessment is premature and may not address the underlying cause. B: Having the mother bring the child back in 1 week delays the necessary examination and potential treatment. D: Telling the mother that this is normal without proper assessment could lead to overlooking a potential health issue that requires intervention.

Correct Answer: A

Rationale: The correct answer is A: auricle. The auricle is the visible, outer portion of the ear made up of movable cartilage and skin. It serves to collect sound waves and direct them into the ear canal. The other choices are incorrect because the concha (B) is the concave cavity leading to the ear canal, the outer meatus (C) is the ear canal itself, and the mastoid process (D) is a bony protrusion behind the ear that has no role in sound collection.

Correct Answer: B

Rationale: The correct answer is B (XI; asking the patient to shrug her shoulders against resistance). This is the correct choice because the nurse suspects damage to the spinal accessory nerve (CN XI), which innervates the trapezius and sternocleidomastoid muscles. Asking the patient to shrug her shoulders against resistance tests the function of the trapezius muscle, which is innervated by CN XI. This examination helps to assess the integrity of the nerve and its ability to innervate the muscle. Palpating the anterior and posterior triangles (choice A) is not specific to CN XI function. Percussing the sternomastoid and submandibular neck muscles (choice C) is related to CN XII, not CN XI. Assessing for a positive Romberg's sign (choice D) is not relevant to testing the function of CN XI.

Correct Answer: B

Rationale: Correct Answer: B Rationale: 1. Whispering two-syllable words ensures a low volume, requiring the patient to focus on clarity. 2. Asking the patient to repeat tests their ability to hear and understand the whispered words accurately. 3. Whispering helps eliminate the influence of lip-reading, ensuring accurate assessment. Summary: A: Shielding the lips while speaking would hinder the patient's ability to hear clearly. C: Placing a finger in the ear would not be appropriate as it could affect the accuracy of the test. D: Standing at a specific distance does not ensure accurate assessment of hearing ability.

Correct Answer: A

Rationale: The correct answer is A: Age-related hearing loss begins in the mid-40s. This is because presbycusis, or age-related hearing loss, typically starts around the mid-40s due to natural aging processes affecting the inner ear. Choice B is incorrect as the progression of hearing loss can vary, being gradual for some individuals but not necessarily slow for everyone. Choice C is incorrect as high-frequency tone loss, not low-frequency, is commonly associated with aging. Choice D is incorrect as difficulty hearing consonants is more related to specific types of hearing loss, not solely age-related changes.

Correct Answer: C

Rationale: The correct answer is C because the nurse should use the Snellen chart positioned 6.1 m (20 ft) away to assess visual acuity. This is the standard method for testing distance vision. The nurse should ask the patient to read the letters on the chart from the top row down, covering one eye at a time if necessary. This method provides an accurate measurement of visual acuity at a distance. A: Performing the confrontation test assesses visual fields, not visual acuity. B: Using a Jaeger card is for near vision testing, not distance visual acuity. D: Assessing the ability to read newsprint at a close distance does not provide an accurate measurement of visual acuity at a distance.

Correct Answer: D

Rationale: The correct answer is D: Second-hand cigarette smoke. Exposure to second-hand smoke can irritate and inflame the lining of the Eustachian tube, making young children more susceptible to ear infections. This is supported by research showing a clear link between exposure to cigarette smoke and increased rates of ear infections in children. Family history (A) may contribute to genetic predisposition but is not a direct risk factor. Air conditioning (B) does not directly cause ear infections. Excessive cerumen (C) can lead to blockages but is not a primary risk factor for infections.

Correct Answer: A

Rationale: The correct answer is A: lesions that run together. Confluent lesions refer to merging or blending of individual lesions to form a larger lesion. This indicates a continuous area of involvement on the skin. Choices B, C, and D do not accurately describe confluent lesions as they refer to different patterns of lesion distribution such as annular, linear, or grouped. The key to identifying confluent lesions is the concept of merging or running together, which is best represented by choice A.

Correct Answer: D

Rationale: The correct answer is D: frenulum. The frenulum is a small fold of tissue that connects the tongue to the floor of the mouth. It helps to limit the movement of the tongue, preventing excessive movement that could lead to injury. The uvula (A) is a soft tissue dangling at the back of the throat, the palate (B) is the roof of the mouth, and papillae (C) are small raised structures on the tongue's surface. These structures are not involved in connecting the tongue to the floor of the mouth.
