What percentage of term newborns have a congenital heart disease due to environmental risk factors such as maternal alcoholism or drug ingestion?

Correct Answer: A

Rationale: The correct answer is A: 2% to 4%. According to research, 2% to 4% of term newborns have congenital heart disease due to environmental risk factors such as maternal alcoholism or drug ingestion. Choices B, C, and D provide percentages that are higher than the actual prevalence of congenital heart disease in newborns caused by environmental factors, making them incorrect.

Correct Answer: C

Rationale: The correct answer is to determine the reasons the nurses are not taking scheduled breaks. This action is crucial as it allows the charge nurse to understand the underlying causes for the behavior. By identifying the reasons, the nurse can then address the root of the issue effectively. Option A is incorrect because discussing time management strategies may not address the specific reasons for not taking breaks. Option B is incorrect as providing coverage for breaks does not address the underlying cause of the issue. Option D is also incorrect as reviewing policies should come after understanding the reasons for the behavior.

Correct Answer: A

Rationale: Low birth weight is defined as 2500 grams or less at birth, regardless of gestational age. This means that any newborn weighing 2500 grams or less is considered to have a low birth weight, irrespective of how many weeks they were in the womb. Choices B, C, and D are incorrect because they specify a weight of 1500 grams or less, which is not the standard definition of low birth weight. The correct definition is 2500 grams or less, not influenced by gestational age.

Correct Answer: D

Rationale: The correct answer is D, The Glasgow Scale. The Glasgow Coma Scale is specifically designed to assess a patient's level of consciousness by evaluating eye opening, verbal response, and motor response. Choices A, B, and C are incorrect because the Snellen Scale is used for vision testing, the Norton Scale is used for assessing the risk of pressure sores, and the Morse Scale is used for evaluating a patient's risk of falling, not for determining the level of consciousness.

Correct Answer: A

Rationale: The correct answer is A: 'Nurses are assistants to physicians.' The public image of nurses, as portrayed by the media, often positions them as assistants to physicians. This perception stems from historical depictions and the traditional hierarchy within healthcare settings. Choice B is incorrect because it reflects how nurses perceive their patients, not how the public views nurses. Choice C is incorrect as nurses are part of the broader healthcare team but are not seen as fundamentally different from other healthcare providers by the public. Choice D is incorrect as while nurses play a crucial role in shaping healthcare, the public perception often focuses more on their supportive role in the healthcare system.

Correct Answer: A

Rationale: In clients with diabetes, regulated food intake is crucial for controlling blood glucose levels. Choice A is the correct answer because maintaining consistent meal sizes and timings helps in managing blood sugar levels effectively. Choice B is incorrect because while monitoring salt and sugar intake is important, it is not the primary consideration in this scenario. Choice C is incorrect as the focus is on regulating food intake rather than aiding digestion. Choice D is also incorrect because consuming large meals can indeed lead to fluctuations in blood glucose levels, but the primary concern in this case is the regulation of food intake for better control of diabetes.

Correct Answer: B

Rationale: A beach ball is appropriate for an 18-month-old as it is safe and can help with motor skills development. Choice A, storybooks, may not be suitable for this age group due to limited attention span. Choice C involves interaction with other children which may not always be feasible in a healthcare setting. Choice D, pickup sticks, poses a choking hazard and is not suitable for toddlers.

Correct Answer: A

Rationale: The correct principle of teaching to follow when reinforcing teaching and instructing the patient is to sequence the instruction from the least complex to the most complex. This approach facilitates learning by building upon simpler concepts before moving to more advanced ones. Choice B is incorrect because assuming the patient knows little or nothing about the topic may not always be accurate and can be patronizing. Choice C is incorrect as it does not focus on the direct teaching approach to the patient. Choice D is incorrect as using medically oriented terms may confuse the patient rather than facilitate understanding.

Correct Answer: B

Rationale: The correct answer is B. Second-degree atrioventricular heart block is also known as Mobitz II. In Mobitz II, some atrial impulses are blocked from reaching the ventricles, resulting in occasional dropped beats. Third-degree atrioventricular heart block is known as complete heart block, where no atrial impulses reach the ventricles. First-degree atrioventricular heart block is a condition where there is delayed conduction between the atria and ventricles but all atrial impulses are eventually conducted to the ventricles.
