Nursing Elites

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 a voice test, how should the nurse provide words for the client to repeat?

• A. Spoken in a soft tone of voice by the nurse about 5 feet in front of the client
• B. Whispered by the nurse from the client's side at a distance of 1 to 2 feet from the ear being tested
• C. Spoken by the nurse from the client's side in a normal tone of voice about 10 feet from the ear being tested
• D. Whispered at a distance of 20 feet by the nurse while he or she is standing in front of the client

Correct answer: B

Rationale: During a voice test, the nurse should whisper words from the client's side at a distance of 1 to 2 feet from the ear being tested. This distance helps prevent transmission around the head and ensures accurate testing of one ear at a time. By standing close to the client and whispering, the nurse prevents lip-reading and compensatory actions by the client. The client with normal hearing should be able to repeat each word correctly. Choices A, C, and D are incorrect. Choice A is wrong as the voice should be whispered, not spoken in a soft tone. Choice C is inaccurate because a distance of 10 feet is too far for precise testing. Choice D is incorrect as whispering from a distance of 20 feet would not effectively test the client's hearing.

3. A nurse is assisting with data collection on the language development of a 9-month-old infant. Which developmental milestone does the nurse expect to note in an infant of this age?

• A. The infant babbles single consonants
• B. The infant babbles
• C. The infant says 'Mama.'
• D. The infant says 'Mama.'

Correct answer: D

Rationale: An 8- to 9-month-old infant can string vowels and consonants together. The first words, such as 'Mama,' 'Daddy,' 'bye-bye,' and 'baby,' begin to have meaning. A 1- to 3-month-old infant produces cooing sounds. Babbling is common in a 3- to 4-month-old. Single-consonant babbling occurs between 6 and 8 months of age. Therefore, the milestone of the infant saying 'Mama' is the most appropriate for a 9-month-old, indicating early language development. The other choices are developmentally inaccurate for a 9-month-old infant.

4. 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.

5. An adult client undergoes various diagnostic tests to determine the pumping ability of the heart. The nurse notes that the results of these tests indicate that the client's cardiac output is 5 L/min. The nurse makes which conclusion?

• A. The client has a low cardiac output.
• B. The client has a high cardiac output.
• C. The client has a normal cardiac output.
• D. The client will need a blood transfusion.

Correct answer: C

Rationale: A cardiac output of 5 L/min falls within the normal range for a resting adult, which typically ranges between 4 and 6 L/min. Cardiac output is calculated as the stroke volume (volume of blood in each systole) multiplied by the heart rate. Therefore, a cardiac output of 5 L/min is considered normal. Choices A and B are incorrect as they misinterpret the result as either low or high, which is not the case based on the provided information. Choice D is unrelated to the client's cardiac output and thus incorrect.
