Nursing Elites

1. A 9-month-old infant who is not sitting independently has been diagnosed with ataxic cerebral palsy (CP). Which clinical manifestations would the nurse expect to see in the baby?

• A. Hypotonia and muscle instability
• B. Hypertonia and persistence of primitive reflexes
• C. Tremors and exaggerated posturing
• D. Hemiplegia and hypertonia

Correct answer: A

Rationale: In ataxic cerebral palsy, the characteristic features include hypotonia (low muscle tone) and muscle instability. These manifestations contribute to the infant's difficulty in achieving independent sitting. Hypertonia (increased muscle tone) and persistence of primitive reflexes, as mentioned in option B, are more commonly associated with other types of cerebral palsy like spastic CP. Tremors and exaggerated posturing (option C) are not typical features of ataxic CP. Hemiplegia (paralysis of one side of the body) and hypertonia (increased muscle tone) mentioned in option D are more commonly seen in other types of cerebral palsy, such as spastic CP.

2. A healthcare provider is preparing to administer ibuprofen 5 mg per kg every 6 hours PRN for temperatures above 38.0 degrees Celsius or 100.5 degrees Fahrenheit to an infant who weighs 17.6 lb. The infant has a temperature of 38.4 degrees Celsius or 101.2 degrees Fahrenheit. Available is ibuprofen liquid 100 mg/5 ml. How many milliliters should the healthcare provider administer to the infant?

• A. 12 ml
• B. 6 ml
• C. 2 ml
• D. 1 ml

Correct answer: C

Rationale: To calculate the correct dosage, first convert the infant's weight to kilograms: 17.6 lb = 8 kg. The prescribed dose is 5 mg/kg, so for an 8 kg infant, the total dose required is 40 mg. Since the available ibuprofen liquid is 100 mg/5 ml, to find out how many milliliters to administer, divide the total dose (40 mg) by the concentration of the liquid (100 mg/5 ml), which equals 2 ml. Therefore, the healthcare provider should administer 2 ml of ibuprofen to the infant.

3. A parent of a child with attention deficit hyperactivity disorder (ADHD) is being taught by a nurse. Which instruction should the nurse include in the teaching?

• A. Administer methylphenidate at bedtime.
• B. Increase stimuli in the child's environment.
• C. Administer an extra dose of medication if the child is overactive.
• D. Maintain a consistent bedtime routine.

Correct answer: D

Rationale: Maintaining a consistent bedtime routine is essential for children with ADHD as it helps in managing their symptoms effectively. Consistency in bedtime routines aids in regulating the child's sleep patterns, promoting better rest, and ultimately improving their behavior and focus during the day.

4. The renin-angiotensin-aldosterone system plays an important role in maintaining blood pressure. Which compound in this system is most powerful at raising blood pressure?

• A. Angiotensin I
• B. Angiotensin II
• C. Angiotensin III
• D. Renin

Correct answer: B

Rationale: Angiotensin II is the most potent compound in the renin-angiotensin-aldosterone system for raising blood pressure. It acts as a powerful vasoconstrictor, leading to increased systemic vascular resistance. Angiotensin II is formed from angiotensin I through the action of the angiotensin-converting enzyme. While renin initiates the cascade by converting angiotensinogen to angiotensin I, it is angiotensin II that exerts the strongest pressor effect.

5. A neonate with a meningomyelocele is scheduled for surgery in the morning. Which nursing action is appropriate for this neonate?

• A. Applying a diaper to prevent contamination of the sac
• B. Positioning the newborn in a side-lying position
• C. Encouraging the mother to hold the newborn because she will not be able to pick him up after surgery
• D. Positioning the newborn in a prone position

Correct answer: D

Rationale: Positioning the newborn in a prone position is appropriate for a neonate with a meningomyelocele before surgery. Placing the newborn in this position helps prevent pressure on the sac, reducing the risk of damaging it and promoting optimal surgical outcomes. Applying a diaper (choice A) may not be recommended as it can increase pressure on the sac. Positioning the newborn in a side-lying position (choice B) or encouraging the mother to hold the newborn (choice C) are not ideal actions before surgery as they do not address the specific needs of a neonate with a meningomyelocele.
