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. During the examination of a client's throat, a nurse touches the posterior wall with a tongue blade and elicits the gag reflex. The nurse documents normal function of which cranial nerves?
- A. Cranial nerves V and VI
- B. Cranial nerves XII and VIII
- C. Cranial nerves XII and VIII
- D. Cranial nerves IX and X
Correct answer: D
Rationale: The correct answer is cranial nerves IX (glossopharyngeal nerve) and X (vagus nerve). When the nurse touches the posterior pharyngeal wall with a tongue blade and elicits the gag reflex, it indicates normal function of these nerves. Cranial nerves V (trigeminal nerve) and VI (abducens nerve) are not directly responsible for the gag reflex. Cranial nerves XII (hypoglossal nerve) and VIII (vestibulocochlear nerve) are not directly involved in eliciting the gag reflex. Testing cranial nerve I involves smell function, and cranial nerve II is related to eye examinations, making them irrelevant in this scenario.
3. A mother brings her 1-year-old child to the clinic. The child has no record of previous immunizations, and the mother confirms the child has not been immunized. Teaching by the nurse should include which of the following?
- A. Immunizations may be started at any age.
- B. The recommended immunization schedule should be followed.
- C. If a primary series of immunizations is interrupted, it can be continued.
- D. Delaying the start of vaccines does not increase the risk of reaction.
Correct answer: A
Rationale: The correct answer is 'Immunizations may be started at any age.' While there is a recommended immunization schedule, immunizations can be initiated at any age. It is essential to emphasize the flexibility in starting immunizations. The statement 'The recommended immunization schedule should be followed' is too rigid; while recommended, there is flexibility in initiation. Choice C is correct as an interrupted series can be continued without restarting. The statement 'Delaying the start of vaccines does not increase the risk of reaction' is correct. Delaying does not increase the risk of reaction; in fact, it is important to start immunizations to protect the child and the community.
4. A nurse is determining the estimated date of delivery for a pregnant client using Nagele's rule and notes documentation that the date of the client's last menstrual period was August 30, 2013. The nurse determines the estimated date of delivery to be which date?
- A. 30-May-14
- B. 6-Jun-14
- C. 6-Jul-14
- D. 6-May-14
Correct answer: B
Rationale: Nagele's rule is a method used to estimate the date of delivery for pregnant clients. The rule involves subtracting 3 months and adding 7 days to the date of the first day of the last normal menstrual period, then adjusting the year. Subtracting 3 months from August 30, 2013, brings the date to May 30, 2013; adding 7 days results in June 6, 2013. Finally, after correcting the year, the estimated date of delivery is June 6, 2014. Therefore, the correct answer is June 6, 2014. Choices A, C, and D are incorrect because they do not follow the accurate calculation based on Nagele's rule.
5. While assisting with data collection of an adult client, a nurse asks the client to identify various odors. In this technique, which cranial nerve is the nurse assessing?
- A. Optic
- B. Abducens
- C. Olfactory
- D. Hypoglossal
Correct answer: C
Rationale: The correct answer is 'Olfactory.' The olfactory nerve is responsible for the sense of smell. Assessing this nerve involves testing the client's ability to identify various odors. Loss of smell, head trauma, abnormal mental status, and suspected intracranial lesions are conditions where testing the olfactory nerve is essential. The optic nerve is evaluated for visual acuity and visual fields. The abducens nerve is usually assessed alongside the oculomotor and trochlear nerves, focusing on pupil size, regularity, light reactions, accommodation, and extraocular movements. The hypoglossal nerve is examined by inspecting the tongue, not by assessing the sense of smell.
