Nursing Elites

1. You are managing a 10-month-old infant who has had severe diarrhea and vomiting for 3 days and is now showing signs of shock. You have initiated supplemental oxygen therapy and elevated the lower extremities. En route to the hospital, you note that the child's work of breathing has increased. What must you do first?

• A. Lower the extremities and reassess the child
• B. Begin positive pressure ventilations and reassess the child
• C. Place a nasopharyngeal airway and increase the oxygen flow
• D. Listen to the lungs with a stethoscope for abnormal breath sounds

Correct answer: A

Rationale: In this scenario, the infant is presenting with signs of respiratory distress, as evidenced by the increased work of breathing. Lowering the extremities can help reduce the workload on the diaphragm and improve respiratory mechanics. This action can be beneficial in optimizing the infant's breathing before considering more invasive interventions. Option B, initiating positive pressure ventilations, should be considered if the infant's condition deteriorates further and not as the first step. Option C, placing a nasopharyngeal airway and increasing oxygen flow, is not indicated as the primary intervention for increased work of breathing. Option D, listening to the lungs with a stethoscope, may provide additional information but is not the most urgent action needed in this situation.

2. When teaching a class about trisomy 21, the instructor would identify the cause of this disorder as:

• A. nondisjunction.
• B. X-linked recessive inheritance.
• C. genomic imprinting.
• D. autosomal dominant inheritance.

Correct answer: A

Rationale: Trisomy 21, also known as Down syndrome, is caused by nondisjunction, which is an error in cell division that leads to the presence of an extra chromosome 21. This additional chromosome alters the normal genetic makeup, resulting in the characteristics associated with Down syndrome. Therefore, the correct answer is nondisjunction (Choice A). Choices B, C, and D are incorrect because Trisomy 21 is not caused by X-linked recessive inheritance, genomic imprinting, or autosomal dominant inheritance. Understanding the specific genetic mechanism involved in Trisomy 21 is crucial for grasping the basis of this chromosomal disorder.

3. A 3-month-old infant has been hospitalized with respiratory syncytial virus (RSV). What is the priority intervention?

• A. Administering an antiviral agent
• B. Clustering care to conserve energy
• C. Offering oral fluids to promote hydration
• D. Providing an antitussive agent when necessary

Correct answer: B

Rationale: The priority intervention for a 3-month-old infant hospitalized with respiratory syncytial virus (RSV) is to cluster care to conserve energy. Infants with RSV often have difficulty breathing and need to rest frequently. Clustering care involves grouping nursing interventions to allow for longer periods of rest between activities, which helps prevent exhaustion and conserve the infant's energy. Administering an antiviral agent is not the primary intervention for RSV, as it is a viral infection and antiviral agents are not typically used for RSV. Offering oral fluids is important for hydration but may not be the priority when the infant is struggling to breathe. Providing an antitussive agent should be done judiciously and under medical guidance, as suppressing the cough reflex can be detrimental in RSV cases where coughing helps clear airway secretions.

4. After completing an oral examination of a healthy 2-year-old child, the parent asks when the child should first be taken to the dentist. When is the most appropriate time in the child’s life for the nurse to suggest?

• A. Before starting school
• B. Within the next few months
• C. When the first deciduous teeth are lost
• D. At the next dental visit of a family member

Correct answer: B

Rationale: It is recommended that a child should visit the dentist within the next few months after turning two years old. This allows for early dental check-ups to monitor oral health, detect any issues early on, and establish a good oral hygiene routine. Choice A ('Before starting school') is not as specific and may delay the child's first dental visit. Choice C ('When the first deciduous teeth are lost') is too late for the first dental visit, as preventive care should start earlier. Choice D ('At the next dental visit of a family member') is not ideal as the child's dental needs should be addressed independently of family members' visits.

5. On the third day of hospitalization, the nurse observes that a 2-year-old toddler who had been screaming and crying inconsolably begins to regress and is now lying quietly in the crib with a blanket. What stage of separation anxiety has developed?

• A. Denial
• B. Despair
• C. Mistrust
• D. Rejection

Correct answer: B

Rationale: The correct answer is B: 'Despair'. In separation anxiety, the stage of despair is characterized by regression and withdrawal after the initial protest. The toddler's shift from intense crying to lying quietly with a blanket demonstrates this withdrawal behavior. Choice A, 'Denial', is incorrect as denial involves refusing to accept the reality of separation. Choice C, 'Mistrust', is incorrect as it relates to a lack of trust rather than the stage of separation anxiety described in the scenario. Choice D, 'Rejection', is incorrect as it does not reflect the behavior of the toddler in the scenario, which is more indicative of withdrawal and regression.
