Nursing Elites

1. What information should the nurse provide to parents of a 3-year-old boy with Duchenne muscular dystrophy who inquire about the disease and future children?

• 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: Duchenne muscular dystrophy is an X-linked recessive disorder caused by mutations in the DMD gene on the X chromosome. This disorder primarily affects males because they have one X chromosome, inherited from their mothers, who may be carriers of the mutated gene. Females have two X chromosomes, providing a protective effect as the normal gene on one X chromosome can compensate for the mutated gene on the other. Therefore, the nurse should explain to the parents that Duchenne muscular dystrophy is an inherited X-linked recessive disorder, which is why their son has the disease and why there is a risk of passing it on to future sons. Choice B is incorrect as it inaccurately implies that the lack of dystrophin in mothers impacts their sons' muscle groups. Choice C is incorrect as it suggests a viral infection caused the muscle damage, which is not the case with Duchenne muscular dystrophy. Choice D is incorrect as it attributes the muscle weakness to birth trauma instead of the genetic nature of the disorder.

2. 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 a significant finding indicating a potential health issue that needs immediate attention. It may be a sign of a skin condition, such as a diaper rash, which can cause discomfort and pain for the infant. Addressing this concern promptly is crucial to prevent further complications and ensure the baby's well-being. The other choices may also be important in assessing the overall situation of the family, but in terms of immediate care for the infant, the severe skin breakdown takes priority.

3. During a well-baby check, the nurse hides a block under the baby's blanket, and the baby looks for the block. Which normal growth and development milestone is the baby developing?

• A. Separation anxiety.
• B. Associative play.
• C. Object prehension.
• D. Object permanence.

Correct answer: D

Rationale: When a baby looks for a hidden object, it demonstrates the development of object permanence. This milestone is significant as it signifies the baby's understanding that objects continue to exist even when they are not visible. It is a crucial aspect of cognitive development in infancy. Choice A, separation anxiety, refers to distress when separated from a primary caregiver and is not demonstrated in this scenario. Choice B, associative play, involves interactive play with others and is not relevant to object search. Choice C, object prehension, refers to the ability to grasp and hold objects, which is not specifically demonstrated by looking for a hidden object in this context.

4. The healthcare provider is evaluating the effects of thyroid therapy used to treat a 5-month-old with hypothyroidism. Which behavior indicates that the treatment has been effective?

• A. Laughs readily, turns from back to side.
• B. Has strong Moro and tonic neck reflexes.
• C. Keeps fists clenched, opens hands when grasping an object.
• D. Can lift head, but not chest when lying on abdomen.

Correct answer: A

Rationale: In infants, laughing readily and turning from back to side are indicative of normal development. These behaviors indicate that the thyroid therapy is effective, as they suggest the baby is achieving age-appropriate milestones. A 5-month-old infant should be able to laugh readily and turn from back to side, showing progress in motor and social development. Choices B, C, and D describe behaviors that are not specific to the expected developmental milestones of a 5-month-old. Strong Moro and tonic neck reflexes, clenched fists, and limited ability to lift the chest when lying on the abdomen are not necessarily indicative of the effectiveness of thyroid therapy for hypothyroidism.

5. The caregiver discovers a 6-month-old infant unresponsive and calls for help. After opening the airway and finding the infant is still not breathing, what action should the caregiver take?

• A. Palpate femoral pulse and check for regularity.
• B. Deliver cycles of 30 chest compressions and 2 breaths.
• C. Give two breaths that make the chest rise.
• D. Feel the carotid pulse and check for adequate breathing.

Correct answer: C

Rationale: Providing two breaths that make the chest rise is the correct action in this situation. This helps to deliver oxygen to the infant's lungs and body, which is crucial in a situation where the infant is not breathing. Chest rise indicates successful ventilation, and it is an essential step in pediatric resuscitation, especially for infants. Choices A, B, and D are incorrect because palpating the femoral pulse, delivering chest compressions, and feeling the carotid pulse are not the initial actions to take when an infant is not breathing. The priority is to provide effective breaths to establish ventilation.
