In experimental research, randomization is used to:

Correct Answer: B

Rationale: The correct answer is B because randomization helps minimize bias by ensuring that participants are assigned to groups randomly, reducing the likelihood of systematic differences between groups. This helps establish a causal relationship between the treatment and outcomes. Choice A is incorrect because randomization does not guarantee a representative sample. Choice C is incorrect as randomization does not determine the sample size. Choice D is incorrect as controlling for variables is typically done through experimental design or statistical methods, not just randomization.

Correct Answer: B

Rationale: The correct answer is B: Discovery phase. During the discovery phase of a lawsuit, both parties gather and exchange evidence and information relevant to the case. A deposition is a key component of the discovery phase where witnesses provide sworn testimony. In this scenario, the nurse manager would likely be asked to provide information related to the case. The other choices are incorrect because: A: Complaint phase - This is when the lawsuit is initiated by the plaintiff filing a complaint. C: Decision phase - There is no specific legal phase known as the decision phase in the typical legal process. D: Trial phase - This phase comes after discovery when the case goes to trial, where the evidence is presented and a decision is made by the court.

Correct Answer: B

Rationale: The correct answer is B: 2-3 drops into the conjunctiva. This is because eye drops should be administered directly onto the conjunctiva to ensure optimal absorption and effectiveness. Placing drops into the conjunctiva also helps to minimize spillage and ensures the medication reaches the intended target area. Other choices are incorrect because dropping the medication from inner to outer canthus (A) may cause the drops to miss the eye or flow out, and choice C and D are incomplete.

Correct Answer: A

Rationale: The correct answer is A: Fantasy filled imagination. At the age of seven, children typically engage in imaginative play and have a rich fantasy life. This is a crucial aspect of their spiritual development as it allows them to explore abstract concepts and emotions. It helps them develop empathy, creativity, and a sense of wonder. Going to church every Sunday (choice B) may be a part of religious upbringing but does not directly address the child's spiritual development at this age. Choice C and D are likely incomplete options.

Correct Answer: B

Rationale: The correct answer is B because painless lumps in the breast are more concerning as they are often associated with breast cancer. Painful lumps are more likely to be benign cysts or fibroadenomas. Choice A is incorrect as pain is not always an indicator of severity. Choice C is also incorrect as breastlessness is not a known term in medical context.
