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. 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.

3. A nurse demonstrates the procedure for bathing a newborn to a new mother. The next day, the nurse watches as the mother bathes the infant. The nurse determines that the mother is performing the procedure correctly if the mother performs which action?

• A. Uses a cotton-tipped swab to carefully clean inside the infant's nose
• B. Uncovers only the body part being washed
• C. Washes the diaper area first
• D. Washes the infant's chest first

Correct answer: B

Rationale: When bathing a newborn, it is crucial to follow a specific sequence for thorough cleaning and safety. The correct sequence includes starting with the eyes and face, then moving to the external ear, areas behind the ears, neck, hands, arms, legs, and finally the diaper area. Keeping the infant warm is essential, so only the body part being washed should be uncovered. Using a cotton-tipped swab to clean inside the infant's nose is not recommended due to the risk of injury if the infant moves suddenly. Washing the diaper area first is incorrect as it should be done towards the end of the bath to prevent contamination. Washing the infant's chest first is also incorrect as it deviates from the recommended bathing sequence for a newborn.

4. A nurse notes the presence of variable decelerations on the fetal heart rate monitor strip and suspects cord compression. The nurse should immediately perform which action?

• A. Insert a gloved finger into the mother's vagina to feel for cord compression
• B. Position the mother so that her hips are elevated
• C. Notify the registered nurse
• D. Perform a vaginal examination on the mother

Correct answer: B

Rationale: When variable decelerations on the fetal heart rate monitor strip suggest cord compression, the immediate action the nurse should take is to reposition the mother to alleviate the compression. Elevating the mother's hips or changing her position can help shift the fetal presenting part and relieve pressure on the cord. This action aims to improve or resolve the variable decelerations. Contacting the registered nurse may be necessary, but it is not the immediate action required in this situation. Performing a vaginal examination is contraindicated due to the potential risk of further compromising blood flow through the umbilical cord. Inserting a gloved finger into the mother's vagina to feel for the cord is also not recommended as it poses a similar risk of exacerbating the situation.

5. A nurse preparing to assist with data collection of the abdomen asks the client to void and then assists the client into a supine position. Which primary finding does the nurse expect to note on percussing all four quadrants of the abdominal cavity?

• A. Dullness
• B. Tympany
• C. Borborygmus
• D. Hyperresonance

Correct answer: B

Rationale: The nurse expects to primarily note tympany when percussing the abdomen. Tympany should predominate because air in the intestines rises to the surface when the client is in a supine position. Dullness is usually heard over a distended bladder, adipose tissue, fluid, or a mass. Borborygmus, which refers to hyperperistalsis, is typically heard on auscultation, not percussion. Hyperresonance is present with gaseous distention, not the typical finding when percussing all four quadrants of the abdomen.
