NCLEX PN Practice Questions Quizlet

1. A nurse assisting with data collection is preparing to assess the optic nerve. The nurse performs this examination by using which technique?

A. Assessing visual acuity
B. Inspecting the eyelids for ptosis
C. Assessing pupil constriction
D. Assessing ocular movements

Correct answer: Assessing visual acuity

Rationale: The correct technique to assess the optic nerve is by testing visual acuity and visual fields through confrontation. Visual acuity involves assessing the clarity of vision, which directly correlates with the function of the optic nerve. Inspecting the eyelids for ptosis is unrelated to optic nerve assessment. Assessing pupil constriction is more related to the assessment of cranial nerves controlling eye movements, particularly the oculomotor nerve. Assessing ocular movements is related to testing the abducens, oculomotor, and trochlear nerves, not specifically the optic nerve.

2. At what age are yearly mammograms recommended to start?

A. Yearly mammograms are recommended starting at age 25.
B. Yearly mammograms are recommended starting at age 40.
C. Yearly mammograms are not necessary unless there is a family history of breast cancer.
D. Yearly mammograms are recommended starting at age 20 and continuing until menopause begins.

Correct answer: Yearly mammograms are recommended starting at age 40.

Rationale: The correct answer is B. The American Cancer Society recommends yearly mammograms starting at age 40 and continuing for as long as a woman is in good health. Clinical breast examination should be done about every 3 years for women in their 20s and 30s and every year for women age 40 and older. Women should know how their breasts normally look and feel and report any breast change promptly to the healthcare provider. Breast self-examination should be done monthly starting when a woman is in her 20s. Choice A is incorrect as mammograms are not recommended to start at age 25. Choice C is incorrect as yearly mammograms are still recommended even without a family history of breast cancer. Choice D is incorrect as the recommended age for starting yearly mammograms is 40, not 20.

3. A pregnant client is being educated by a nurse on nutrition and foods rich in folic acid. Which food item does the nurse inform the client contains the highest amount of folic acid?

A. Pinto beans
B. Lettuce
C. Oranges
D. Broccoli

Correct answer: Pinto beans

Rationale: Pinto beans contain the highest amount of folic acid among the options provided, with 294 mcg per 1-cup serving. Oranges contain 44 mcg per 1-cup serving, lettuce contains 60 mcg per 1-cup serving, and broccoli contains 78 mcg per 1-cup serving. Therefore, pinto beans are the best choice for increasing folic acid intake during pregnancy. Choosing oranges, lettuce, or broccoli would not provide as much folic acid compared to pinto beans, making them less optimal choices for meeting folic acid requirements during pregnancy.

4. When inspecting the ears for cerumen impaction, the nurse checks for which finding?

A. Redness and swelling of the tympanic membrane
B. An external auditory canal that is longer than normal
C. The presence of edema in the external auditory canal
D. A yellowish or brownish waxy material in the external auditory canal

Correct answer: A yellowish or brownish waxy material in the external auditory canal

Rationale: When inspecting the ears for cerumen impaction, the nurse should look for a yellowish or brownish waxy material in the external auditory canal. Cerumen, also known as ear wax, is a secretion that can become impacted due to various reasons. It is produced by the vestigial apocrine sweat glands in the external ear canal. Cerumen may partially obscure the eardrum or totally occlude the ear canal. The other options, redness and swelling of the tympanic membrane, an external auditory canal that is longer than normal, and the presence of edema in the external auditory canal, are not indicative findings of cerumen impaction.

5. How often should a 5-year-old child undergo a dental examination?

A. Every 6 months
B. Whenever a new primary tooth erupts
C. Once a year
D. Every 3 months

Correct answer: Every 6 months

Rationale: For a 5-year-old child, dental examinations should be conducted every 6 months. This frequency allows for early detection of dental issues and promotes good oral health. Choices B, C, and D are incorrect because waiting for a new primary tooth to erupt, having an examination once a year, or every 3 months are not the recommended intervals for dental check-ups in this age group. It is essential to adhere to the standard guideline of every 6 months to ensure regular monitoring and preventive care for the child's dental health.
