Nursing Elites

1. A newborn is admitted to the neonatal intensive care unit (NICU) with choanal atresia. Which part of the infant’s body should the nurse assess?

• A. Rectum
• B. Nasopharynx
• C. Intestinal tract
• D. Laryngopharynx

Correct answer: B

Rationale: Choanal atresia is a congenital condition that presents with a blockage in the nasal passages at the junction of the nasal cavity and the nasopharynx. To assess and confirm the diagnosis of choanal atresia, the nurse should focus on assessing the nasopharynx. Choices A, C, and D are incorrect as choanal atresia specifically involves a blockage in the nasal passages, not the rectum, intestinal tract, or laryngopharynx. By assessing the nasopharynx, the severity of the obstruction can be determined, aiding in planning appropriate interventions for the newborn.

2. The nurse is reviewing the laboratory test results of a child diagnosed with disseminated intravascular coagulation (DIC). What would the nurse interpret as indicative of this disorder?

• A. Shortened prothrombin time
• B. Increased fibrinogen level
• C. Positive fibrin split products
• D. Increased platelets

Correct answer: C

Rationale: Positive fibrin split products are indicative of disseminated intravascular coagulation (DIC). In DIC, there is widespread clotting and subsequent consumption of clotting factors, leading to the formation of fibrin split products. A shortened prothrombin time (Choice A) is not typically seen in DIC as it indicates faster clotting, which is opposite to the pathophysiology of DIC. An increased fibrinogen level (Choice B) may be observed in the early stages of DIC due to the compensatory increase in production, but it is not a definitive indicator. Increased platelets (Choice D) may be seen in the early stages of DIC due to the body's attempt to compensate for clot formation, but it is not a specific finding for DIC.

3. A child has been admitted to the pediatric unit with a severe asthma attack. What type of acid-base imbalance should the nurse expect the child to develop?

• A. metabolic alkalosis caused by decreased acid metabolites production
• B. respiratory alkalosis caused by decreased respiratory rate and carbon dioxide retention
• C. respiratory acidosis caused by impaired respirations and increased carbonic acid formation
• D. metabolic acidosis caused by the kidneys' inability to compensate for increased carbonic acid production

Correct answer: C

Rationale: In a severe asthma attack, the child is likely to develop respiratory acidosis due to impaired respirations leading to the retention of carbon dioxide, which combines with water to form carbonic acid. This results in the pH imbalance characterized by an excess of carbonic acid. Choices A, B, and D are incorrect. Metabolic alkalosis (Choice A) is not typically associated with severe asthma attacks; respiratory alkalosis (Choice B) would involve a decrease, not an increase, in carbon dioxide levels; and metabolic acidosis (Choice D) is not the primary acid-base imbalance seen in severe asthma attacks.

4. A parent calls the clinic because their child has ingested a small amount of household bleach. What should the nurse advise?

• A. Administer activated charcoal
• B. Induce vomiting immediately
• C. Call the poison control center
• D. Take the child to the emergency department

Correct answer: C

Rationale: The correct answer is to advise the parent to call the poison control center. When a child ingests household bleach, it is important to seek guidance from professionals who can provide specific and immediate advice on managing the situation. Administering activated charcoal (Choice A) is not recommended for household bleach ingestion. Inducing vomiting immediately (Choice B) can lead to further complications and is not the recommended first response. Taking the child to the emergency department (Choice D) should be done based on the advice received from the poison control center.

5. A 3-year-old child with a history of frequent respiratory infections is being evaluated for cystic fibrosis. What diagnostic test should the nurse anticipate will be ordered?

• A. Chest X-ray
• B. Sweat chloride test
• C. Pulmonary function test
• D. Sputum culture

Correct answer: B

Rationale: The sweat chloride test is the gold standard diagnostic test for cystic fibrosis as it measures the concentration of chloride in sweat. In cystic fibrosis, there is an abnormal transport of chloride across epithelial membranes, leading to elevated sweat chloride levels. A chest X-ray may show characteristic changes in the lungs associated with cystic fibrosis, but it is not a definitive diagnostic test. Pulmonary function tests assess lung function but do not specifically diagnose cystic fibrosis. Sputum culture may identify respiratory infections but does not confirm the diagnosis of cystic fibrosis.
