health assessment practice questions

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.

Correct Answer: A

Rationale: The correct answer is A because drooling is a common sign of teething in infants. The nurse's response should validate the mother's observation to build trust and rapport. Choice B is incorrect because teething can start as early as 3 months. Choice C is incorrect as drooling is a normal developmental milestone in infants. Choice D is incorrect as infants do not consciously control saliva production.

Correct Answer: C

Rationale: The correct answer is C: at the level of the C7 vertebra. The vertebra prominens refers to the spinous process of the C7 vertebra, which is the most prominent bony landmark at the base of the neck. Assessing this area allows the nurse to accurately locate and evaluate tenderness reported by the physician. Choices A, B, and D are incorrect as they do not correspond to the location of the vertebra prominens. Option A is too high, above the diaphragm; option B is too low, lateral to the knee cap; and option D is too low, at the level of the T11 vertebra.

Correct Answer: A

Rationale: The correct answer is A: "Are you aware of having any allergies?" This question is appropriate because the patient's symptoms of pale, grey, and swollen nasal mucosa suggest an allergic reaction. By asking about allergies, the nurse can gather important information to determine the cause of the symptoms. B: "Do you have an elevated temperature?" - This question is not directly related to the patient's nasal symptoms and does not address the likely allergic reaction. C: "Have you had any symptoms of a cold?" - While cold symptoms may present similarly to allergies, the patient's specific symptoms of pale, grey, and swollen nasal mucosa are more indicative of an allergic reaction. D: "Have you been having frequent nosebleeds?" - This question does not directly address the patient's current symptoms and is not likely related to the nasal mucosa appearance described.

Correct Answer: B

Rationale: The correct answer is B: Dehydration. Depressed and sunken fontanelles in an infant indicate dehydration due to decreased fluid volume. Dehydration causes a decrease in tissue turgor, leading to the fontanelles appearing sunken. Rickets (A) is a condition characterized by weak or soft bones due to vitamin D deficiency. Mental retardation (C) is a developmental disorder, not related to fontanelle appearance. Increased intracranial pressure (D) would cause bulging fontanelles, not depressed fontanelles. Therefore, the most likely condition in this case is dehydration.
