Nursing Elites

1. The LPN/LVN identifies crepitus when examining the chest of a newborn who was delivered vaginally. Which further assessment should the nurse perform?

• A. Elicit a positive scarf sign on the affected side.
• B. Observe for an asymmetrical Moro (startle) reflex.
• C. Watch for swelling of fingers on the affected side.
• D. Note paralysis of the affected extremity and muscles.

Correct answer: B

Rationale: Crepitus in a newborn's chest following vaginal delivery may indicate a clavicle fracture. Observing for an asymmetrical Moro reflex is essential because it can indicate potential nerve damage or fracture, which may be associated with the crepitus identified during the examination.

2. A mother who is breastfeeding her baby receives instructions from the nurse. Which instruction is most effective to prevent nipple soreness?

• A. Wear a cotton bra.
• B. Increase nursing time gradually.
• C. Correctly place the infant on the breast.
• D. Manually express a small amount of milk before nursing.

Correct answer: C

Rationale: The most effective instruction to prevent nipple soreness when breastfeeding is to correctly place the infant on the breast. Proper latch-on techniques ensure that the baby is properly positioned, reducing the risk of nipple soreness. When the baby is positioned correctly, they can nurse effectively without causing discomfort to the mother.

3. The parents of a 3-year-old boy with Duchenne muscular dystrophy (DMD) ask, 'How can our son have this disease? We are wondering if we should have any more children.' What information should the nurse provide these parents?

• A. This is an inherited X-linked recessive disorder, which primarily affects male children in the family.
• B. The male infant had a viral infection that went unnoticed and untreated, leading to muscle damage.
• C. The lack of the protein dystrophin in the mother can impact the XXX muscle groups of males.
• D. Spinal cord damage due to birth trauma during a breech vaginal birth weakens the muscles.

Correct answer: A

Rationale: The correct answer is A. Duchenne muscular dystrophy is an X-linked recessive disorder, meaning the gene mutation causing DMD is located on the X chromosome. Males have one X chromosome and one Y chromosome, so if the X chromosome they inherit from their mother carries the mutated gene, they will develop DMD. Females have two X chromosomes, so they are carriers of the gene but are usually not affected by the disease. Therefore, the nurse should explain to the parents that DMD is an inherited X-linked recessive disorder that primarily affects male children in the family.

4. The healthcare provider prescribes magnesium sulfate 6 grams intravenously (IV) to be infused over 20 minutes for a client with preterm labor. The IV bag contains magnesium sulfate 20 grams in dextrose 5% in water 500 mL. How many mL/hour should the nurse set the infusion pump?

• A. 150 mL/hour
• B. 250 mL/hour
• C. 50 mL/hour
• D. 275 mL/hour

Correct answer: A

Rationale: To calculate the infusion rate, first, determine the total volume to be infused (6 grams of magnesium sulfate) over a specific time frame (20 minutes). Then, calculate the concentration of magnesium sulfate in the IV bag to determine the mL/hour rate. The IV bag contains 20 grams of magnesium sulfate in 500 mL of solution, which means there are 4 grams of magnesium sulfate per 100 mL. Since 6 grams are required, the nurse should set the pump to deliver 150 mL/hour to infuse the prescribed dose over 20 minutes. Choice B, 250 mL/hour, is incorrect because it miscalculates the amount of magnesium sulfate infused per hour. Choice C, 50 mL/hour, is incorrect as it is too slow to deliver the required dose in the specified time frame. Choice D, 275 mL/hour, is incorrect as it overestimates the infusion rate and would deliver the dose too quickly.

5. What action should be implemented when preparing to measure the fundal height of a pregnant client?

• A. Have the client empty her bladder.
• B. Request the client lie on her left side.
• C. Perform Leopold's maneuvers first.
• D. Give the client some cold juice to drink.

Correct answer: A

Rationale: The correct action when preparing to measure the fundal height of a pregnant client is to have the client empty her bladder. This is essential to ensure an accurate measurement because a full bladder can displace the uterus and affect the accuracy of the assessment. Choice B is incorrect because the client should lie flat on her back, not on her left side, to measure fundal height accurately. Choice C is incorrect because Leopold's maneuvers are used to determine the position of the fetus, not to measure fundal height. Choice D is incorrect as giving the client cold juice is not necessary for measuring fundal height.
