Correct Answer: B

Rationale: The correct answer is "B: Rolls over." At 6 months, most infants can roll over, which increases the risk of falls. Emphasizing the infant's ability to roll over is crucial to highlight the need for careful supervision and accident prevention. Choices A, C, and D are incorrect because sitting up, crawling short distances, and standing while holding on to furniture typically develop later in an infant's motor skills progression and are not as directly associated with an increased risk of accidents at this stage.

Correct Answer: B

Rationale: During a check-up for a child with eczema, assessing compliance with treatment regimens is a key nursing intervention. This helps ensure that the child is following the prescribed treatment plan effectively, which is crucial in managing eczema and preventing flare-ups. Changing a bandage on a cut is not directly related to managing eczema. Discussing systemic corticosteroid therapy may be part of the visit, but assessing compliance is more immediate and essential. Assessing the child's fluid volume is important for overall health assessment but not specifically related to managing eczema.

Correct Answer: B

Rationale: The correct answer is B: Rolls over. At 6 months, most infants can roll over, increasing the risk of falls. It is important to emphasize to the parent the need for careful supervision to prevent accidents. While choices A, C, and D are also milestones in infant motor development, rolling over at this age poses a higher risk of accidents due to the increased mobility and potential for falls.

Correct Answer: D

Rationale: The correct answer is D, Rheumatic fever. Rheumatic fever can develop as a complication of untreated strep throat caused by beta-hemolytic streptococcus. It is characterized by inflamed joints and can lead to serious complications such as heart infections. Tetanus (choice A) is caused by a bacterial toxin affecting the nervous system, Influenza (choice B) is a viral respiratory illness, and Scarlet fever (choice C) is also caused by streptococcus but is characterized by a sandpaper-like rash and strawberry tongue. However, in the scenario described, the nurse is most concerned about the child developing rheumatic fever due to the potential serious consequences associated with it.

Correct Answer: C

Rationale: The correct action to take first when a child with sickle cell anemia presents with severe chest pain, fever, cough, and dyspnea is to notify the practitioner because acute chest syndrome is suspected. This condition is a medical emergency requiring prompt intervention. Administering oxygen or pain medication may be necessary interventions but should not precede notifying the practitioner. Stroke is not typically associated with these symptoms in sickle cell anemia.
