Nursing Elites

1. How does a double-blind experiment work?

• A. Both subject groups take turns receiving each treatment.
• B. Neither subjects nor researchers know which subjects are in the control or experimental group.
• C. Neither group of subjects knows whether they are in the control or experimental group, but the researchers do not know.
• D. Both subject groups know whether they are in the control or experimental group, but the researchers do not know.

Correct answer: B

Rationale: The correct answer is B. In a double-blind experiment, neither the subjects nor the researchers know which subjects are in the control or experimental group. This helps to eliminate bias and ensure that the results are more objective. Choice A is incorrect as in a double-blind experiment, subjects do not take turns receiving each treatment; it is about masking the treatment allocation. Choice C is incorrect because it implies that the researchers are aware of the group allocation, which goes against the principle of blinding in a double-blind study. Choice D is incorrect as both subject groups should not know whether they are in the control or experimental group to maintain the blindness of the study.

2. Why must a child with acute laryngotracheobronchitis be kept NPO?

• A. The epinephrine administration may cause nausea and vomiting
• B. The child is being hydrated with IV fluids
• C. The child may not feel hungry
• D. Rapid respirations pose a risk for aspiration

Correct answer: D

Rationale: In acute laryngotracheobronchitis, rapid respirations increase the risk of aspiration due to compromised airway protection and potential for secretions to enter the lungs. Keeping the child NPO helps prevent the risk of aspiration pneumonia. Choice A is incorrect because epinephrine is not typically used for laryngotracheobronchitis. Choice B is incorrect as hydration with IV fluids does not eliminate the risk of aspiration. Choice C is also incorrect because the child being hungry is not the primary reason for keeping them NPO in this condition.

3. How should a healthcare provider address concerns about a child’s developmental milestones?

• A. Recommend delaying intervention until school age
• B. Provide resources for early intervention services
• C. Suggest dietary changes
• D. Avoid further assessment

Correct answer: B

Rationale: Correct Answer: Providing resources for early intervention services is crucial for addressing developmental concerns and supporting the child's growth and development. Early intervention is key to improving outcomes. Recommending delaying intervention until school age (Choice A) is not advised as addressing issues early leads to better results. Suggesting dietary changes (Choice C) is not the primary approach to addressing developmental milestones. Avoiding further assessment (Choice D) can impede the timely identification and management of developmental delays.

4. How should the nurse manage a child with acute lymphoblastic leukemia (ALL) who is receiving chemotherapy?

• A. Avoid all physical activity
• B. Ensure strict infection control measures
• C. Increase daily caloric intake
• D. Limit fluid intake

Correct answer: B

Rationale: The correct answer is B: Ensure strict infection control measures. Children with acute lymphoblastic leukemia (ALL) who are undergoing chemotherapy have compromised immune systems, making them highly susceptible to infections. Implementing strict infection control measures, such as hand hygiene, limiting exposure to sick individuals, and maintaining a clean environment, is essential to prevent infections. Choice A is incorrect because avoiding all physical activity may not be necessary as long as the child's activity level is appropriate. Choice C is incorrect because increasing daily caloric intake is important to support the child's nutritional needs during treatment. Choice D is incorrect because limiting fluid intake is not typically recommended unless specifically advised by the healthcare provider.

5. What is a common symptom of a vitamin D deficiency in children?

• A. Frequent infections
• B. Bone pain and tenderness
• C. Excessive thirst
• D. Unexplained bruising

Correct answer: B

Rationale: Bone pain and tenderness are indeed common symptoms of vitamin D deficiency in children. Vitamin D plays a crucial role in bone health and growth. The deficiency can lead to weakened bones, causing pain and tenderness. Choices A, C, and D are incorrect. Frequent infections are not a typical symptom of vitamin D deficiency in children; excessive thirst is more commonly associated with conditions like diabetes, and unexplained bruising is not directly linked to vitamin D deficiency.
