Nursing Elites

1. When caring for a 7-week-old infant with hypothyroidism, the nurse explains that the prevention of what complication is dependent on the administration of oral thyroid replacement therapy and is critical for the child?

• A. Excessive growth
• B. Cognitive impairment
• C. Damage to the nervous system
• D. Damage to the urinary system

Correct answer: B

Rationale: The correct answer is B: Cognitive impairment. The treatment of choice for congenital and acquired hypothyroidism is oral thyroid hormone replacement therapy. Prompt treatment is especially critical in the infant with congenital hypothyroidism to avoid permanent cognitive impairment. Excessive growth (Choice A) is not a common complication of hypothyroidism in infants. Damage to the nervous system (Choice C) and damage to the urinary system (Choice D) are not typically associated with untreated hypothyroidism in infants.

2. Which additional congenital malformation is expected in 80% of infants with a myelomeningocele?

• A. Cerebral palsy
• B. Hydrocephalus
• C. Meningitis
• D. Neuroblastoma

Correct answer: B

Rationale: Hydrocephalus is the additional congenital malformation expected in 80% of infants with a myelomeningocele. Myelomeningocele is commonly associated with hydrocephalus due to the abnormal accumulation of cerebrospinal fluid in the brain. Cerebral palsy (Choice A) is a motor disorder but not typically associated with myelomeningocele. Meningitis (Choice C) is an infection of the meninges and is not a congenital malformation. Neuroblastoma (Choice D) is a type of cancer that originates in immature nerve cells and is not a typical association with myelomeningocele.

3. A client admitted with left-sided heart failure has a heart rate of 110 beats per minute and is becoming increasingly dyspneic. Which additional assessment finding by the nurse supports the client’s admitting diagnosis?

• A. Jugular vein distention.
• B. Crackles in the lung bases.
• C. Peripheral edema.
• D. Bounding peripheral pulses.

Correct answer: B

Rationale: The correct answer is B: Crackles in the lung bases. Crackles in the lung bases are indicative of pulmonary congestion, which is a classic sign of left-sided heart failure. Left-sided heart failure leads to a backup of blood into the lungs, causing fluid leakage into the alveoli and resulting in crackles upon auscultation. Choices A, C, and D are less specific to left-sided heart failure. Jugular vein distention can be seen in right-sided heart failure, peripheral edema can be seen in both right and left-sided heart failure, and bounding peripheral pulses are more indicative of conditions like hyperthyroidism or anemia rather than specifically supporting left-sided heart failure.

4. When conducting a class for parents about sudden infant death syndrome (SIDS), the nurse instructs the class that the infant should be placed in which position to sleep?

• A. Right side-lying
• B. Left side-lying
• C. Prone
• D. Supine

Correct answer: D

Rationale: The correct answer is D, supine. The American Academy of Pediatrics recommends placing infants on their back, or supine, to sleep as it has been shown to reduce the risk of SIDS. Choices A, B, and C are incorrect because placing infants on their right side, left side, or prone (on their stomach) respectively are not recommended sleeping positions due to the increased risk of SIDS associated with those positions.

5. The parents of a child who has been diagnosed with sickle cell anemia ask why their child experiences pain. What is the most likely cause of the pain?

• A. Inflammation of the vessels
• B. Obstructed blood flow
• C. Overhydration
• D. Stress-related headaches

Correct answer: B

Rationale: The correct answer is B: Obstructed blood flow. In sickle cell anemia, the sickle-shaped red blood cells can clump together, obstructing blood flow in the vessels. This obstruction leads to tissue hypoxia (lack of oxygen) and necrosis, causing pain. Choice A, inflammation of the vessels, is not the primary cause of pain in sickle cell anemia. Choice C, overhydration, is unrelated to the pathophysiology of sickle cell anemia. Choice D, stress-related headaches, is not a characteristic symptom of sickle cell anemia.
