Nursing Elites

1. The healthcare provider is preparing to administer digoxin (Lanoxin) to a 6-month-old infant with heart failure. The healthcare provider notes that the infant’s heart rate is 90 beats per minute. What should the healthcare provider do next?

• A. Administer the medication as prescribed
• B. Hold the medication and notify the healthcare provider
• C. Reassess the heart rate in 30 minutes
• D. Administer half the prescribed dose

Correct answer: B

Rationale: In this scenario, the correct action is to hold the medication and notify the healthcare provider. Digoxin should be withheld if the infant’s heart rate is below 100 beats per minute. Administering digoxin in this situation can further slow down the heart rate in infants with heart failure, leading to potential adverse effects. Reassessing the heart rate in 30 minutes is not the best immediate action to take, as prompt notification and withholding of the medication are crucial. Administering the medication as prescribed or giving half the dose can exacerbate the situation by potentially further lowering the heart rate.

2. The healthcare provider is assessing an infant with diarrhea and lethargy. Which finding should the provider identify that is consistent with early dehydration?

• A. Tachycardia
• B. Bradycardia
• C. Dry mucous membranes
• D. Decreased skin turgor

Correct answer: A

Rationale: Tachycardia is a common early sign of dehydration in infants. It is important for healthcare providers to be vigilant in monitoring infants with these symptoms, as prompt intervention is crucial to prevent further complications.

3. A mother brings her 3-month-old infant to the clinic because the baby does not sleep through the night. Which finding is most significant in planning care for this family?

• A. The mother is a single parent and lives with her parents
• B. The mother states the baby is irritable during feedings
• C. The infant's formula has been changed twice
• D. The diaper area shows severe skin breakdown

Correct answer: D

Rationale: Severe skin breakdown in the diaper area is significant as it indicates a potential severe issue that needs immediate attention to prevent further complications. Skin breakdown can lead to infections and discomfort for the infant, making it a priority in planning care for this family. The other findings, such as the mother's living situation, baby's irritability during feedings, or formula changes, are important but do not pose immediate risks to the infant's health compared to severe skin breakdown.

4. The mother of a 9-month-old girl provides the practical nurse with information about her daughter's diet. Which statement by the mother may indicate why the infant has been diagnosed with iron-deficiency anemia?

• A. She almost never drinks sugary water.
• B. She has been on whole milk for 7 months.
• C. She likes to chew on bread as a snack.
• D. She doesn't like to eat peaches or pears.

Correct answer: B

Rationale: The correct answer is B. Infants should not be given cow's milk before 1 year of age as it can interfere with iron absorption and lead to anemia. Choice A is incorrect as avoiding sugary water is actually a good practice. Choice C is unrelated to iron-deficiency anemia. Choice D, not liking peaches or pears, is also not directly related to iron-deficiency anemia.

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

• A. This is an inherited X-linked recessive disorder, which primarily affects male children in the family
• B. The striated muscle groups of males can be impacted by a lack of the protein dystrophin in their mothers
• C. The male infant had a viral infection that went unnoticed and untreated so muscle damage was incurred
• D. Birth trauma with a breech vaginal birth causes damage to the spinal cord, thus weakening the muscles

Correct answer: A

Rationale: The correct answer is A. Duchenne muscular dystrophy is an X-linked recessive disorder that primarily affects males. It is crucial for the nurse to explain to the parents that this condition follows an inheritance pattern where the gene mutation responsible for the disorder is located on the X chromosome. Males have only one X chromosome, so if they inherit the mutated gene, they will develop the disease. Females, on the other hand, have two X chromosomes, providing a backup copy that can compensate for the mutation. Understanding this inheritance pattern is essential for family planning decisions, as the risk of passing on the disorder to future children can be explained based on this genetic inheritance. Choices B, C, and D are incorrect because they do not address the genetic basis of Duchenne muscular dystrophy or its inheritance pattern, which is crucial information for the parents in this scenario.
