health assessment practice questions nursing

Correct Answer: B

Rationale: The correct answer is B: pearly grey and slightly concave. This is because a healthy tympanic membrane should appear pearly grey in color and slightly concave in shape. The pearly grey color indicates normal transparency and reflection of light, while the slightly concave shape is indicative of a normal eardrum. Choice A is incorrect as a light pink color and slight bulge are not characteristic of a healthy tympanic membrane. Choice C is incorrect because a pulled-in appearance at the base of the cone of light suggests retraction, which is abnormal. Choice D is incorrect as a whitish color with a small fleck of light is not a typical presentation of a healthy tympanic membrane.

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: B

Rationale: The correct answer is B: Lyme disease. The presentation of a red circular rash with central clearing, known as erythema migrans, following a hiking trip in the summer is highly indicative of Lyme disease. The specific distribution of the rash across the midriff and behind the knees aligns with typical areas where the rash appears in Lyme disease cases. This rash is a hallmark sign of early Lyme disease caused by the bacterium Borrelia burgdorferi transmitted through the bite of an infected tick. Other answer choices are incorrect because rubeola presents with a different rash pattern, an allergy to mosquito bites would not typically present in this manner, and Rocky Mountain spotted fever typically presents with a different rash appearance and distribution.

Correct Answer: D

Rationale: The correct answer is D: Enlarged regional lymph nodes. In otitis externa, there may be regional lymphadenopathy due to inflammation and infection. Rhinorrhea (A) is associated with upper respiratory infections, not otitis externa. Periorbital edema (B) is seen in conditions like periorbital cellulitis. Pain over the maxillary sinuses (C) is indicative of sinusitis, not otitis externa.

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.
