1. What is an important nursing responsibility when a dysrhythmia is suspected?

A. Order an immediate electrocardiogram
B. Count the radial pulse every minute for five times
C. Count the apical pulse for 1 full minute and compare the rate with the radial pulse rate
D. Have someone else take the radial pulse simultaneously with the apical pulse

Correct answer: C

Rationale: When a dysrhythmia is suspected, it is important for nurses to count the apical pulse for a full minute and compare it with the radial pulse rate. This method helps in identifying dysrhythmias because discrepancies between the apical and radial pulse rates can indicate irregular heart rhythms. Option A is incorrect because ordering an immediate electrocardiogram may not always be feasible or necessary as a first step. Option B, counting the radial pulse multiple times, is less accurate than comparing the apical and radial pulse rates. Option D involves an unnecessary step of having another person take simultaneous pulses when the nurse can do it effectively alone.

2. The nurse is teaching the parents of a 1-month-old girl with Down syndrome how to maintain good health for the child. Which instruction would the nurse be least likely to include?

A. Getting cervical radiographs between 3 and 5 years of age
B. Adhering to the special dietary needs of the child
C. Getting an echocardiogram before 3 months of age
D. Monitoring for symptoms of respiratory infection

Correct answer: B

Rationale: The correct answer is B. While special dietary needs may be important for a child with Down syndrome, they are typically not the primary concern for a 1-month-old. The nurse would be least likely to focus on this aspect as immediate issues such as monitoring for congenital heart defects (echocardiogram), cervical spine abnormalities (radiographs), and respiratory infections are more critical in the early months. Adhering to dietary needs is important, but it is usually addressed as the child grows older and is not the priority during the infant stage.

3. Which best describes a full-thickness (third-degree) burn?

A. Erythema and pain
B. Skin showing erythema followed by blister formation
C. Destruction of all layers of skin evident with extension into subcutaneous tissue
D. Destruction injury involving underlying structures such as muscle, fascia, and bone

Correct answer: C

Rationale: The correct answer is C: Full-thickness burns involve the destruction of all layers of skin, extending into the subcutaneous tissue. This type of burn causes severe damage and loss of sensation due to nerve destruction. Choice A, erythema and pain, describes superficial burns (first-degree). Choice B, skin showing erythema followed by blister formation, describes partial-thickness burns (second-degree). Choice D, destruction injury involving underlying structures such as muscle, fascia, and bone, goes beyond the description of full-thickness burns.

4. While assessing an 18-month-old child, a nurse observes that the toddler can crawl upstairs but needs assistance when climbing the stairs upright. What does this action indicate to the nurse?

A. Presence of talipes equinovarus
B. Reflective of neurologic damage
C. Expected behavior in a toddler of this age
D. Existence of developmental dysplasia of the hip

Correct answer: C

Rationale: At 18 months of age, needing assistance to climb stairs upright is considered normal behavior for a toddler. Crawling upstairs is a different motor skill and does not necessarily correlate with the ability to climb stairs. The child is still developing gross motor skills, and climbing stairs upright typically requires more coordination and strength, which may not be fully developed at this age. Choices A, B, and D are not relevant in this scenario as the observed behavior is within the expected range of development for an 18-month-old child.

5. A child with a diagnosis of bronchiolitis is admitted to the hospital. What is the most important nursing intervention?

A. Administering bronchodilators
B. Providing respiratory therapy
C. Monitoring oxygen saturation
D. Encouraging fluid intake

Correct answer: B

Rationale: The most important nursing intervention for a child with bronchiolitis is providing respiratory therapy. This intervention helps to maintain airway patency and improve breathing by assisting with mucus clearance and ventilation. Administering bronchodilators (Choice A) may be considered in some cases, but it is not the most crucial intervention for bronchiolitis. Monitoring oxygen saturation (Choice C) is important but is not as directly impactful as providing respiratory therapy. Encouraging fluid intake (Choice D) is important for hydration but does not directly address the respiratory distress associated with bronchiolitis.
