health assessment practice questions

Correct Answer: D

Rationale: The correct answer is D: It helps equalize air pressure on both sides of the tympanic membrane. The eustachian tube connects the middle ear to the nasopharynx, allowing for pressure equalization. During activities like swallowing or yawning, the tube opens to allow air to flow in or out, maintaining equal pressure. This function is crucial for proper hearing and preventing discomfort or damage to the tympanic membrane. Choice A is incorrect as cerumen is produced by ceruminous glands in the ear canal, not the eustachian tube. Choice B is incorrect as the eustachian tube normally remains closed and opens only intermittently during specific actions. Choice C is incorrect as the eustachian tube does not connect the middle and outer ear; it connects the middle ear to the nasopharynx.

Correct Answer: C

Rationale: The correct answer is C: bruising on the buccal mucosa or gums. This is the most relevant choice as it is a common sign of physical abuse in children. Bruising in unusual places or patterns, such as the mouth, should raise suspicion. Swollen, red tonsils (A) are more likely related to infection rather than abuse. Ulcerations on the hard palate (B) can also be due to various non-abuse related reasons. Small yellow papules along the hard palate (D) are typically harmless and not indicative of abuse. It is crucial for the nurse to recognize signs of potential abuse and take appropriate action to protect the child.

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: Dysphagia. In a stroke patient with right-sided facial drooping, dysphagia is highly likely due to the involvement of the facial nerve, leading to difficulty swallowing. Epistaxis (A) is nosebleeds, agenesis (B) is the absence of a body part, and xerostomia (D) is dry mouth, which are not directly related to facial drooping in stroke patients. Dysphagia is a common complication post-stroke due to impaired muscle control, making it the most likely concern for the nurse to suspect in this case.

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.
