NCLEX PN Practice Questions Quizlet
1. The nurse is teaching parents of a newborn about feeding their infant. Which of the following instructions should the nurse include?
- A. Use the defrost setting on microwave ovens to warm bottles.
- B. When refrigerating formula, discard partially used bottles after 24 hours.
- C. When using formula concentrate, mix one part concentrate and two parts water.
- D. If a portion of one bottle is left for the next feeding, discard it.
Correct answer: B
Rationale: The correct answer is to use the defrost setting on microwave ovens to warm bottles. It is crucial to be cautious when heating bottles in a microwave to prevent milk from becoming superheated. The defrost setting is recommended, and the formula's temperature should always be checked before feeding the baby. Choice B, which advises to discard partially used bottles of refrigerated formula after 24 hours, is also correct. This is important to prevent the introduction of pathogens by the baby into the formula. Choice C, recommending mixing one part formula concentrate with two parts water, is essential for ensuring the correct dilution. Choice D, suggesting to discard any remaining portion of a bottle for the next feeding, is incorrect. It is not necessary to discard the remaining portion if it has been refrigerated promptly and used within a safe time frame. Adding fresh formula to a partially used bottle is not recommended, as it can lead to the growth of pathogens that may be transferred to the new formula.
2. What is the primary theory that explains a family's concept of health and illness?
- A. Health Belief Model
- B. Education Factor
- C. Family Health Belief Model
- D. Family Dynamics Model
Correct answer: A
Rationale: The correct answer is the Health Belief Model. The Health Belief Model is a widely recognized theory that explains individuals' perceptions and behaviors related to health and illness. It considers factors such as perceived susceptibility, severity of health issues, benefits of action, and barriers to taking action. Choices B, C, and D are incorrect. Choice B, 'Education Factor,' is too general and does not specifically address a family's concept of health and illness. Choice C, 'Family Health Belief Model,' is a combination of terms and not a recognized theory. Choice D, 'Family Dynamics Model,' focuses on family interactions rather than explaining a family's concept of health and illness.
3. What is the primary nutritional deficiency of concern for a strict vegetarian?
- A. vitamin C
- B. vitamin B12
- C. vitamin E
- D. magnesium
Correct answer: B
Rationale: Vitamin B12 is the primary nutritional deficiency of concern for a strict vegetarian. While all mentioned vitamins are essential for overall health, vitamin B12 is particularly important for vegetarians as it is mainly found in animal products. A strict vegetarian diet may lack sufficient vitamin B12 intake, leading to potential health issues like anemia and neurological problems. Vitamin C deficiency is more commonly associated with scurvy, which is preventable with a diet rich in fruits and vegetables. Vitamin E deficiency is rare and usually only seen in specific medical conditions. Magnesium deficiency is not typically a primary concern for strict vegetarians as magnesium can be obtained from a variety of plant-based sources.
4. A nurse is assisting with data collection regarding skin and peripheral vascular findings on a client in later adulthood. Which observation would the nurse expect to note as an age-related finding?
- A. Thin, ridged toenails
- B. Thick skin on the lower legs
- C. Loss of hair on the lower legs
- D. Bounding dorsalis pedis pulse
Correct answer: C
Rationale: In later adulthood, age-related findings include trophic changes associated with arterial insufficiency, such as thin, shiny skin; thin, ridged toenails; and loss of hair on the lower legs. These changes occur normally with aging. Thick skin on the lower legs would not be an expected age-related finding as it typically indicates chronic venous insufficiency. A bounding dorsalis pedis pulse is not typical in later adulthood and may indicate arterial insufficiency, which is not an age-related finding.
5. A nurse reviewing a client's record notes that the result of the client's latest Snellen chart vision test was 20/80. The nurse interprets the client's results in which way?
- A. The client is legally blind.
- B. The client has normal vision.
- C. The client can read at a distance of 20 feet what a client with normal vision can read at 80 feet.
- D. The client can read at a distance of 80 feet what a client with normal vision can read at 20 feet.
Correct answer: D
Rationale: When interpreting visual acuity testing results using the Snellen chart, the recorded numeric fraction represents the distance the client is standing from the chart and the distance a normal eye could read that particular line. A reading of 20/80 means that the client can read at 20 feet what a client with normal vision can read at 80 feet. This indicates visual impairment but does not meet the criteria for legal blindness, which is defined as best-corrected vision in the better eye of 20/200 or worse. Normal visual acuity is 20/20. Therefore, the correct interpretation is that the client can read at a distance of 80 feet what a client with normal vision can read at 20 feet. Choice A is incorrect because 20/80 does not meet the criteria for legal blindness. Choice B is incorrect as the client's vision is impaired. Choice C is incorrect because it reverses the interpretation of the fraction.
