The nurse is reviewing a client's electrocardiogram and determines the PR interval (PRI) is prolonged. What does this finding indicate?

Correct Answer: C

Rationale: When the PR interval is prolonged, it signifies an increased conduction time from the SA node through the AV junction. This finding is characteristic of a first-degree heart block where there is a delay in the electrical conduction at the level of the AV node. Choices A, B, and D are incorrect as they do not accurately reflect the significance of a prolonged PR interval.

Correct Answer: D

Rationale: The correct answer is D. Blepharitis is managed with warm moist compresses to help loosen debris and oils on the eyelids, followed by gentle scrubbing with a mild solution like diluted baby shampoo. This helps in controlling the condition. Choice A is incorrect as using eye patches while sleeping is not a standard recommendation for blepharitis. Choice B is incorrect as wearing sunglasses does not directly treat blepharitis but may help with light sensitivity. Choice C is incorrect as cold compresses are not typically used for blepharitis, as warm compresses are more effective in managing the condition.

Correct Answer: B

Rationale: The correct answer is B) "His smaller size is probably due to the heart disease." This response is the best because it provides an accurate explanation related to the child's congenital heart defect. Children with congenital heart defects often have growth delays due to the increased metabolic demands and compromised cardiac function associated with their condition. By acknowledging the impact of the heart disease on the child's growth, the nurse helps the mother understand the underlying reason for her child's size percentile. Option A) "Does your child seem mentally slower than his peers also?" is incorrect as it introduces an unrelated and potentially insensitive question about the child's mental abilities, which is not relevant to the growth percentile issue. Option C) "Haven't you been feeding him according to recommended daily allowances for children?" is incorrect because it implies that the mother may be at fault for her child's growth percentile, which can be perceived as blaming and unhelpful in addressing the actual medical cause. Option D) "You should not worry about the growth tables. They are only averages for children" is also incorrect as it dismisses the mother's concern and fails to provide her with a valid explanation for her child's growth pattern. In an educational context, it is crucial for nurses to understand the impact of various health conditions on growth and development, especially in pediatric patients. By providing accurate and empathetic explanations to parents, nurses can help them better comprehend their child's health status and collaborate effectively in the child's care plan. This scenario highlights the importance of patient education and communication skills in nursing practice.

Correct Answer: A

Rationale: The correct answer is A: 'Your baby is gaining weight right on schedule.' Tripling of birth weight by 6 months is a normal growth pattern in infants, indicating appropriate weight gain and development. Choice B is unrelated to the question as it focuses on the baby's diet rather than addressing the weight gain concern. Choice C is incorrect as tripling the birth weight is considered a healthy growth pattern, not below normal percentile. Choice D is irrelevant to the mother's question about the adequacy of weight gain.

Correct Answer: A

Rationale: Talking directly to the adolescent is the most appropriate intervention in this scenario. It helps maintain a sense of connection and respect, even if the response is not evident. Maintaining silence may lead to isolation and hinder any potential communication attempts. Playing soothing music may not provide the personal interaction needed for connection. Limiting visitors to immediate family only may deprive the patient of diverse interactions that could be beneficial for their emotional well-being.
