nclex practice questions 2023 health assessment

Correct Answer: B

Rationale: Correct Answer: B Rationale: 1. Bluish lips indicate cyanosis, a sign of inadequate oxygen supply. 2. Dark line along gingival margin suggests lead poisoning. 3. The nurse should assess for other signs of inadequate oxygen supply to determine the severity and underlying cause. 4. This finding is not normal and requires further evaluation to prevent complications. Summary: A: Checking hemoglobin for anemia is not the immediate priority when cyanosis and lead poisoning are suspected. C: Assuming this is a normal finding can lead to overlooking a potentially serious condition. D: Carbon monoxide exposure could be a consideration, but assessing for overall oxygen supply is more crucial in this scenario.

Correct Answer: B

Rationale: The correct answer is B: the patient can read at 6.1 m (20 ft) what a person with normal vision can read at 9.1 m (30 ft). This is because the Snellen notation 20/30 means that the patient can read at 20 feet what a person with normal vision can read at 30 feet. This ratio signifies the patient's visual acuity compared to a person with normal vision. The other choices are incorrect as they do not accurately interpret the Snellen notation or misinterpret the distance at which the patient can read the eye chart.

Correct Answer: C

Rationale: The correct answer is C: The purpose of cerumen is to protect and lubricate the ear. Cerumen, commonly known as earwax, acts as a natural barrier to prevent dust, debris, and microorganisms from entering the ear canal. It also helps to lubricate the skin in the ear canal and prevent dryness and itching. Choice A is incorrect because sticky, honey-colored cerumen is not necessarily a sign of infection; it can occur due to various factors. Choice B is incorrect as the presence of cerumen does not solely indicate poor hygiene; everyone produces earwax regardless of hygiene practices. Choice D is incorrect as cerumen can sometimes block the ear canal and impair sound transmission rather than aid it.

Correct Answer: C

Rationale: The correct answer is C because the presentation of clear vesicles with an erythematous base around them at the lip-skin border is characteristic of herpes simplex virus 1 infection, commonly known as cold sores. Given the patient's recent travel to Hawaii, exposure to the virus is likely. This infection is self-limiting and typically heals in 4 to 10 days without the need for specific treatment. Choice A is incorrect because seeing a skin specialist may not be necessary for a self-limiting viral infection. Choice B is incorrect as a biopsy is not typically indicated for a clear clinical diagnosis of herpes simplex virus infection. Choice D is incorrect as riboflavin deficiency does not present with clear vesicles and erythema at the lip-skin border.

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.
