Correct Answer: C

Rationale: Encouraging bed rest and quiet activities is crucial for a child recovering from a splenectomy with low hemoglobin and hematocrit levels. This approach helps conserve energy, promotes healing, and allows the body to focus on rebuilding red blood cells. Limiting milk and milk products (Choice A) is not directly related to improving the child's condition. Encouraging bed rest and quiet activities (Choice B) is appropriate as it helps in conserving energy and preventing physical exertion. Promoting a diet rich in iron (Choice D) is beneficial for improving hemoglobin levels in the long term, but immediate rest and recovery take precedence in this scenario.

Correct Answer: A

Rationale: The correct action the nurse should take first is to auscultate bowel sounds. This step is crucial to assess bowel activity before proceeding with palpation or administering medications. Assessing bowel sounds can provide valuable information about bowel motility and potential obstructions. Administering an antiemetic or offering pain medication may be necessary but should come after assessing bowel sounds to ensure appropriate treatment. Palpating the abdomen should be avoided initially to prevent potential discomfort or complications, especially if there is suspected abdominal pathology.

Correct Answer: A

Rationale: Placing a client in seclusion without proper justification and documentation can lead to charges of unlawful seclusion and restraint, regardless of the client's compliance. This legal issue arises from the potential violation of the client's rights and must be avoided. Choice B is incorrect as the situation does not involve assault and battery. Choice C is incorrect as past violence alone does not justify seclusion without immediate risk. Choice D is incorrect as seclusion should be used based on individual risk and necessity, not solely for maintaining the therapeutic milieu.

Correct Answer: A

Rationale: A pericardial friction rub is characterized by a scratching sound that occurs during both systole and diastole. It becomes more distinct when the client is sitting up and leaning forward. This indicates an inflammation of the pericardial sac rubbing against the layers of the heart. Heart murmurs (choice B) are abnormal heart sounds caused by turbulent blood flow, not by friction like in a pericardial rub. S3 and S4 heart sounds (choices C and D) are additional heart sounds related to abnormal ventricular filling, not to pericardial friction rubs.
