Nursing Elites

1. 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.

2. 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.

3. A 4-year-old fell from a third-story window and landed on her head. She is semiconscious with slow, irregular breathing and bleeding from her mouth. After performing a jaw-thrust maneuver with simultaneous stabilization of her head, what should you do next?

• A. Suction the oropharynx
• B. Insert a nasopharyngeal airway
• C. Initiate positive pressure ventilations
• D. Administer oxygen via mask

Correct answer: A

Rationale: In this scenario, the patient is experiencing airway compromise due to the fall and potential oropharyngeal obstruction from bleeding. Performing a jaw-thrust maneuver with head stabilization helps maintain the airway patency. The next step should be to suction the oropharynx to clear any blood or secretions, which can obstruct the airway and lead to aspiration. Inserting a nasopharyngeal airway may worsen bleeding or cause further injury to the patient's airway. Initiating positive pressure ventilations can be ineffective if the airway is not cleared first. Administering oxygen via mask is not the immediate priority; ensuring a patent airway by suctioning takes precedence.

4. When counseling a couple who suspect they could have a child with a genetic abnormality, what would be most important for the nurse to incorporate into the plan of care when working with this family?

• A. Gathering information from at least three generations
• B. Informing the family of the need for a wide range of information
• C. Maintaining the confidentiality of the information
• D. Presenting the information in a nondirective manner

Correct answer: D

Rationale: When counseling a couple about the possibility of having a child with a genetic abnormality, it is vital for the nurse to present information in a nondirective manner. This approach empowers the couple to make decisions based on their values and preferences, respecting their autonomy. Gathering information from three generations (Choice A) may not be necessary and might overwhelm the couple with unnecessary data. Informing the family about the need for a wide range of information (Choice B) is not as critical as supporting their decision-making process through a nondirective approach. While maintaining confidentiality (Choice C) is crucial, it is not the most important aspect compared to ensuring the couple can make informed choices that align with their beliefs and wishes.

5. When assessing a child with suspected nephrotic syndrome, what clinical manifestation is the nurse likely to observe?

• A. Jaundice
• B. Edema
• C. Hypertension
• D. Polyuria

Correct answer: B

Rationale: Edema is a hallmark clinical manifestation of nephrotic syndrome. In nephrotic syndrome, there is increased glomerular permeability leading to the loss of proteins, particularly albumin, in the urine. This results in decreased oncotic pressure, leading to fluid shifting into the interstitial spaces and causing edema. Jaundice (Choice A) is not a typical clinical manifestation of nephrotic syndrome. Hypertension (Choice C) is more commonly associated with conditions like glomerulonephritis. Polyuria (Choice D) is not a primary symptom of nephrotic syndrome; instead, patients may have reduced urine output due to fluid retention from edema.
