nclex practice questions 2023 health assessment

Correct Answer: A

Rationale: The correct answer is A: Diabetes. The presence of "cotton wool" or fluffy grey-white cumulus clouds on ophthalmoscopic examination indicates retinal nerve fiber layer infarcts due to microvascular damage, which is a common finding in diabetic retinopathy. This occurs due to ischemia and subsequent axonal swelling. In diabetes, hyperglycemia can lead to damage in the blood vessels supplying the retina, resulting in microaneurysms, hemorrhages, exudates, and ultimately vision loss if left untreated. Summary of other choices: B: Hyperthyroidism - This condition primarily affects the thyroid gland and does not directly cause the characteristic retinal findings described. C: Glaucoma - Glaucoma is a condition characterized by increased intraocular pressure and optic nerve damage, which does not typically present with the specific retinal findings mentioned. D: Hypotension - Low blood pressure may lead to retinal artery occlusion or ischemic optic neuropathy,

Correct Answer: C

Rationale: The correct answer is C: Pull the pinna up and back before inserting the speculum. This is because pulling the pinna up and back straightens the auditory canal, allowing for easier and more accurate insertion of the speculum without causing discomfort or injury. Option A is incorrect as tilting the head forward may obstruct the view. Option B is incorrect as maintaining traction is essential for stability. Option D is incorrect as using the smallest speculum may not provide a clear view or proper insertion depth.

Correct Answer: D

Rationale: The correct answer is D because dry, flaky cerumen can indicate a change in cilia in the ear canal, potentially leading to conductive hearing loss. This warrants further assessment by the nurse to ensure the patient's aural health is not compromised. A: Eczema lesions typically present differently and are not directly related to dry cerumen. B: While hygiene can contribute to cerumen buildup, dry, flaky cerumen alone does not necessarily indicate poor hygiene. C: Dry, flaky cerumen is not considered a normal finding in a healthy ear and should prompt further evaluation.

Correct Answer: B

Rationale: The correct answer is B because rubella can indeed damage the organ of Corti in the fetus, which is responsible for hearing. During the first trimester, when the hearing structures are forming, any damage to the organ of Corti can result in impaired hearing for the infant. Choice A is incorrect because rubella can impact the fetus, including the organs responsible for hearing. Choice C is incorrect because rubella can be harmful to the fetus at any stage of pregnancy, not just the second trimester. Choice D is incorrect because CN VIII (the vestibulocochlear nerve) is not directly affected by rubella, rather it is the organ of Corti that is damaged.

Correct Answer: A

Rationale: Correct Answer: A Rationale: 1. Head control typically develops around 4 months, so it is normal for a 2-month-old to lack this skill. 2. Reassuring the mother that her baby is within the normal developmental range is important for reducing parental anxiety. 3. Avoiding overly alarming responses helps maintain trust and open communication with the parent. Summary: - Choice B is incorrect as it does not address the mother's concern and may come across as dismissive. - Choice C is incorrect as it may unnecessarily worry the mother and lead to undue stress. - Choice D is incorrect as it introduces a serious and unlikely scenario without evidence at this stage of development.
