Nursing Elites

1. A child with a diagnosis of cystic fibrosis is admitted to the hospital. What is the priority nursing intervention?

• A. Administering pancreatic enzymes
• B. Providing respiratory therapy
• C. Providing nutritional support
• D. Encouraging physical activity

Correct answer: A

Rationale: The correct answer is administering pancreatic enzymes. In cystic fibrosis, the pancreas is often affected, leading to insufficient production of digestive enzymes. Administering pancreatic enzymes is crucial to ensure proper digestion and absorption of nutrients. While respiratory therapy, nutritional support, and physical activity are essential components of care for individuals with cystic fibrosis, addressing the digestive aspect by administering pancreatic enzymes takes priority to prevent malnutrition and promote overall health.

2. 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.

3. When teaching the parents of a child with a diagnosis of type 1 diabetes mellitus about insulin administration, what should the nurse emphasize?

• A. Rotate injection sites
• B. Administer insulin before meals
• C. Store insulin in the refrigerator
• D. Administer insulin at bedtime

Correct answer: A

Rationale: The correct answer is to rotate injection sites. This practice helps prevent lipodystrophy, a localized loss of fat tissue that can affect insulin absorption. By rotating sites, the child can avoid developing lumps or indentations in the skin where insulin is repeatedly injected. Administering insulin before meals (choice B) may be necessary for certain types of insulin but is not the priority when teaching about insulin administration. Storing insulin in the refrigerator (choice C) is important for maintaining its potency, but it is not the primary emphasis when teaching about insulin administration. Administering insulin at bedtime (choice D) may be necessary based on the child's insulin regimen but is not the primary consideration for teaching injection techniques and site rotation.

4. A group of students is reviewing the components of the endocrine system. The students demonstrate understanding of the review when they identify what as the primary function of this system?

• A. Regulation of water balance
• B. Hormonal secretion
• C. Cellular metabolism
• D. Growth stimulation

Correct answer: B

Rationale: The primary function of the endocrine system is hormonal secretion. This system is responsible for producing and releasing hormones that regulate various bodily functions such as growth, metabolism, and mood. Choice A, regulation of water balance, is more related to the functions of the renal system rather than the endocrine system. Choice C, cellular metabolism, is a general cellular process that involves various systems, not specific to the endocrine system. Choice D, growth stimulation, though hormones can influence growth, it is not the primary function of the endocrine system. Therefore, the correct answer is B.

5. Which cardiac defects are associated with tetralogy of Fallot?

• A. Right ventricular hypertrophy, atrial and ventricular defects, and mitral valve stenosis
• B. Origin of the aorta from the right ventricle and of the pulmonary artery from the left ventricle
• C. Right ventricular hypertrophy, ventricular septal defect, pulmonic stenosis, and overriding aorta
• D. Altered connection between the pulmonary artery and the aorta, right ventricular hypertrophy, and an atrial septal defect

Correct answer: C

Rationale: Tetralogy of Fallot is characterized by a combination of four specific cardiac defects: right ventricular hypertrophy, ventricular septal defect, pulmonic stenosis, and overriding aorta. Choice A is incorrect as it includes mitral valve stenosis, which is not typically part of tetralogy of Fallot. Choice B describes transposition of the great arteries rather than tetralogy of Fallot. Choice D includes an atrial septal defect, which is not part of the classic presentation of tetralogy of Fallot.
