Correct Answer: B

Rationale: The correct answer is B: Basal cell carcinoma. The clinical presentation of a papule with rounded, pearly borders, central red ulcer, slow growth, and location on the nose is highly indicative of basal cell carcinoma. Basal cell carcinoma commonly presents with these characteristics and is the most common type of skin cancer. It is locally invasive but rarely metastasizes. A: Acne is a common skin condition characterized by comedones, papules, and pustules, not typically presenting with the described features. C: Malignant melanoma usually presents as an asymmetric, irregularly bordered, multicolored lesion with rapid growth and potential for metastasis. D: Squamous cell carcinoma typically presents as a scaly, crusted lesion with potential for metastasis, not showing the described features.

Correct Answer: C

Rationale: The correct answer is C because the frontal sinuses are indeed fairly well developed at birth. This is true as the frontal sinuses start developing around the age of 7-8 years but are present in a rudimentary form at birth. This is because the frontal bone grows rapidly in the first few years of life, allowing for the development of the frontal sinuses. Choice A is incorrect because the sphenoid sinuses are not at full size at birth; they continue to develop throughout childhood. Choice B is incorrect as the maxillary sinuses reach full size around the teenage years, not after puberty. Choice D is incorrect as the frontal sinuses are also present at birth, along with the maxillary and ethmoid sinuses.

Correct Answer: A

Rationale: Step-by-step rationale for why choice A (Tachycardia) is correct: 1. Hyperthyroidism leads to increased production of thyroid hormones. 2. Thyroid hormones can increase metabolic rate and heart rate. 3. Tachycardia is a common symptom of hyperthyroidism due to increased metabolic demand. 4. Therefore, the nurse would most likely find tachycardia on examination in a patient with hyperthyroidism. Summary of why other choices are incorrect: B: Constipation - Constipation is more commonly associated with hypothyroidism, not hyperthyroidism. C: Rapid dyspnea - Dyspnea (shortness of breath) is not a typical symptom of hyperthyroidism. D: Atrophied, nodular thyroid - Hyperthyroidism often presents with an enlarged, not atrophied, thyroid gland due to overactivity. Nodules may be present in conditions like thyroid cancer, but not specific to hyper

Correct Answer: D

Rationale: Rationale for Correct Answer D: Tympanostomy tubes are inserted into the eardrum to help drain fluid from the middle ear, relieve pressure, and prevent infections. This is important in children who have recurrent ear infections or fluid buildup. By allowing drainage, the tubes help improve hearing and reduce the risk of complications. Summary of Incorrect Choices: A) Incorrect - Tympanostomy tubes are placed in the middle ear, not the inner ear. B) Incorrect - Tympanostomy tubes are used for conductive hearing loss, not sensorineural loss. C) Incorrect - Tympanostomy tubes are not permanently inserted and are usually removed after a period of time once they are no longer needed.
