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. When assessing Mr. Lee's eye condition, what general information should the nurse seek?
- A. Type of employment.
- B. Burning or itchy sensation in the eyes.
- C. Position of the eyelids.
- D. Existence of floaters.
Correct answer: A
Rationale: When assessing a patient's eye condition, the nurse should seek general information such as the type of employment, activities, allergies, medications, lenses, and protective devices used. This information helps in understanding potential exposures to irritants and risks related to activities. While the presence of burning or itchy sensation in the eyes, position of the eyelids, and existence of floaters are important aspects to assess during a focused eye examination, during the initial assessment, the type of employment is more relevant for understanding possible environmental factors affecting eye health.
3. While assisting with data collection regarding the neurological system, the nurse asks the client to puff out both cheeks. Which cranial nerve is the nurse assessing?
- A. Vagus
- B. Facial
- C. Abducens
- D. Oculomotor
Correct answer: B
Rationale: The correct answer is B: Facial. Assessment of cranial nerve VII (facial nerve) involves noting mobility and symmetry as the client performs various facial movements, including puffing out the cheeks. Cranial nerve IX (glossopharyngeal nerve) and cranial nerve X (vagus nerve) are tested together for different functions. The abducens, oculomotor, and trochlear nerves are assessed together for eye movements and pupil reactions, not cheek puffing.
4. What is the threshold of dextrose concentrations that can safely be administered through a peripheral IV?
- A. Dextrose concentrations below 20% can be safely administered through a peripheral IV; dextrose concentrations above 20% should not be administered through a peripheral IV.
- B. Dextrose concentrations below 5% can be safely administered through a peripheral IV; dextrose concentrations above 5% should not be administered through a peripheral IV.
- C. Dextrose concentrations below 10% can be safely administered through a peripheral IV; dextrose concentrations above 10% should not be administered through a peripheral IV.
- D. Dextrose concentrations above 5% can be safely administered through a peripheral IV; dextrose concentrations below 5% should not be administered through a peripheral IV.
Correct answer: C
Rationale: Dextrose concentrations below 10% are considered safe for administration through a peripheral IV, as concentrations above this threshold can lead to phlebitis, causing inflammation of the vein. Concentrations above 10% should not be administered through a peripheral IV to prevent vein irritation. Choice A is incorrect because concentrations above 20% are too high for a peripheral IV. Choice B is incorrect as dextrose concentrations below 5% are too low to be effective. Choice D is incorrect because the statement is reversed, suggesting that concentrations above 5% are safe, which is not true.
5. A nurse monitoring a newborn infant notes that the infant's respirations are 40 breaths/min. On the basis of this finding, what is the most appropriate action for the nurse to take?
- A. Contacting the registered nurse
- B. Documenting the findings
- C. Wrapping an extra blanket around the infant
- D. Placing the infant in an oxygen tent
Correct answer: B
Rationale: The normal respiratory rate of a newborn infant is 30 to 60 breaths/min, with an average of 40. Since the infant's respiratory rate falls within the normal range, the most appropriate action for the nurse is to document the findings. Contacting the registered nurse, placing the infant in an oxygen tent, or wrapping an extra blanket around the infant are unnecessary actions as the respiratory rate is normal. Documenting the findings is important to provide a record of the assessment and serve as a baseline for future comparisons if needed.
