nclex practice questions 2023 health assessment

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.

Correct Answer: B

Rationale: The correct answer is B: increased vascularity in the upper respiratory tract as a result of the pregnancy. During pregnancy, hormonal changes lead to increased blood flow in the body, including the nasal passages, causing them to become more sensitive and prone to bleeding. This explains why the woman is experiencing more nosebleeds. Incorrect Choices: A: coagulation problems in the patient - This is incorrect as pregnancy is associated with hypercoagulability rather than coagulation problems. C: increased susceptibility to colds and nasal irritation - While pregnancy can lower immunity, this does not directly cause nosebleeds. D: inappropriate use of nasal sprays - This is not relevant to the situation described and does not explain the increased nosebleeds due to pregnancy.

Correct Answer: B

Rationale: The bright cherry-red coloring in a semiconscious woman found on the floor in her kitchen indicates carbon monoxide poisoning. Carbon monoxide binds to hemoglobin with a higher affinity than oxygen, leading to tissue hypoxia and the characteristic cherry-red coloration. Polycythemia would result in a purplish-red color, carotenemia in a yellow-orange hue, and uremia in a pale or yellowish complexion. Therefore, the correct answer is B, as it aligns with the clinical presentation and pathophysiology of carbon monoxide poisoning.

Correct Answer: D

Rationale: The correct answer is D: A slight amount of lid lag when moving the eyes from a superior position to an inferior position. In the diagnostic positions test, when the eyes move from an extreme superior position to an inferior position, a slight amount of lid lag is expected due to the normal anatomical structure and mechanics of the eye muscles and eyelids. This lag is a normal finding and not indicative of any underlying pathology. Rationale: A: Convergence of vision in both eyes is not a normal finding in the diagnostic positions test as convergence refers to the inward movement of both eyes towards each other to maintain single binocular vision. B: Parallel movement of both eyes is not a specific finding in the diagnostic positions test. The test is designed to assess the movement of the eyes in different directions. C: Nystagmus in extreme superior gaze is not a normal finding and indicates an abnormality in eye movement coordination, not an expected finding in the diagnostic positions test.

Correct Answer: D

Rationale: The correct answer is D because the movement of extraocular muscles is primarily controlled by cranial nerves III, IV, and VI. CN III controls most of the eye movements, CN IV controls the superior oblique muscle, and CN VI controls the lateral rectus muscle. These nerves work together to coordinate eye movements in all directions. Choices A and B are incorrect because age or cataracts do not directly impact the stimulation of extraocular muscles. Choice C is incorrect as CNs I and II are not involved in controlling extraocular muscle movement.
