Nursing Elites

1. Which developmental behavior should the practical nurse identify as normal for a 6-month-old infant?

• A. Rolls over completely.
• B. Creeps on all fours.
• C. Pulls self to a standing position.
• D. Assumes a sitting position independently.

Correct answer: A

Rationale: The correct answer is A: 'Rolls over completely.' By 6 months of age, infants typically achieve the milestone of rolling over completely. This ability demonstrates increasing strength and coordination. Creeping on all fours, pulling self to a standing position, and assuming a sitting position independently are skills that are usually developed at later stages of infancy. Creeping usually occurs around 9-10 months, pulling self to a standing position around 9-12 months, and assuming a sitting position independently around 8 months. Therefore, at 6 months, rolling over completely is the most expected developmental behavior.

2. The nurse is caring for a 3-year-old child who has been recently diagnosed with cystic fibrosis. Which discharge instruction by the nurse is most important to promote pulmonary function?

• A. Chest physiotherapy should be performed before meals and at bedtime
• B. Cough suppressants can be used up to four times a day for relief
• C. Oxygen should be given through a nasal cannula between 4-6 L/min
• D. Exercise is discouraged in order to preserve pulmonary vital capacity

Correct answer: B

Rationale: In cystic fibrosis, thick mucus obstructs the airways, making it difficult to clear from the lungs. Cough suppressants can help reduce the discomfort associated with persistent coughing, allowing the child to cough more effectively to clear the mucus, thus promoting pulmonary function. Chest physiotherapy, not exercise, helps mobilize the mucus. Oxygen therapy may be needed but is not the most important for promoting pulmonary function in this case.

3. A mother brings her 3-week-old infant to the clinic because the baby vomits after eating and always seems hungry. Further assessment indicates that the infant’s vomiting is projectile, and the child seems listless. Which additional assessment finding indicates the possibility of a life-threatening complication?

• A. Irregular palpable pulse
• B. Hyperactive bowel sounds
• C. Underweight for age
• D. Crying without tears

Correct answer: D

Rationale: In this scenario, the infant presenting with vomiting, lethargy, and projectile vomiting indicates a potential serious condition. Crying without tears is a sign of dehydration, a critical condition that can lead to life-threatening complications in infants. Dehydration can rapidly worsen an infant's condition, making prompt intervention crucial to prevent further complications. Irregular palpable pulse (Choice A) could indicate a cardiovascular issue but is less immediately life-threatening in this context. Hyperactive bowel sounds (Choice B) are more indicative of gastrointestinal issues rather than a life-threatening complication. Underweight for age (Choice C) may be concerning for growth-related issues but does not directly indicate a life-threatening complication like dehydration does.

4. The parents of a 3-year-old boy who has 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 muscle groups of males.
• D. Damage to the spinal cord due to birth trauma from a breech vaginal birth weakens the muscles.

Correct answer: A

Rationale: The nurse should inform the parents that Duchenne muscular dystrophy is an X-linked recessive disorder, which primarily affects male children in the family. This genetic condition is caused by a mutation in the dystrophin gene located on the X chromosome. Females are usually carriers of the gene mutation and may pass it on to their sons. Daughters of carrier mothers have a 50% chance of being carriers themselves. Understanding the genetics of DMD can help the parents make informed decisions about family planning and genetic counseling.

5. The nurse is caring for a 4-year-old child who has been diagnosed with measles. Which intervention should the nurse implement to prevent the spread of infection?

• A. Administer antipyretics as prescribed
• B. Place the child in airborne isolation
• C. Encourage fluid intake
• D. Teach the parents about hand hygiene

Correct answer: B

Rationale: Measles is an airborne infection, so placing the child in airborne isolation is crucial to prevent the spread of the virus to others. Airborne isolation precautions help contain infectious respiratory droplets and reduce the risk of transmission to healthcare workers, other patients, and visitors. Administering antipyretics, encouraging fluid intake, and teaching parents about hand hygiene are important aspects of care but do not directly address the prevention of the spread of measles, which requires airborne precautions.
