Question 1 of 5
During an examination of a female patient, the nurse observes lymphadenopathy and suspects an acute infection. Acutely infected lymph nodes would be:
Correct Answer: A
Rationale: The correct answer is A: clumped. Acutely infected lymph nodes typically present as clumped due to inflammation and enlargement of multiple nodes in close proximity. This clustering is a result of the immune response to the infection. Choice B: unilateral is incorrect as lymphadenopathy in acute infection can be unilateral or bilateral. Choice C: firm but freely movable is incorrect as acutely infected lymph nodes are usually tender and may not be freely movable due to inflammation. Choice D: hard and nontender is incorrect as acutely infected lymph nodes are usually tender and may not be hard.
Question 2 of 5
During a well-baby checkup, the mother expresses concern that her 2-month-old infant is not able to hold her head up when she is pulled to a sitting position. Which of the following responses by the nurse is appropriate?
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.
Question 3 of 5
During ocular examinations, the nurse keeps in mind that movement of the extraocular muscles is:
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.
Question 4 of 5
Which of the following statements regarding visual pathways and visual fields is true?
Correct Answer: B
Rationale: The correct answer is B because the image formed on the retina is indeed upside down and reversed from its actual appearance in the outside world due to the way light rays are refracted and focused by the cornea and lens. This phenomenon is known as the inverted retinal image. Choice A is incorrect as visual pathways cross at the optic chiasm, so the right side of the brain interprets vision for the left visual field from both eyes. Choice C is incorrect as light rays are refracted at the cornea and lens, not through the transparent media of the eye before striking the pupil. Choice D is incorrect as light impulses are conducted through the optic nerve to the occipital lobes, not the temporal lobes, where the primary visual cortex is located.
Question 5 of 5
Which of the following physiological changes is responsible for presbyopia?
Correct Answer: B
Rationale: The correct answer is B, loss of lens elasticity. Presbyopia is the age-related loss of near vision due to the lens becoming less flexible, making it harder to focus on close objects. With aging, the lens loses its ability to change shape, affecting near vision. Other choices are incorrect because presbyopia is primarily related to changes in the lens, not the cornea (A), adaptation to darkness (C), or distance vision abilities (D).
