Correct Answer: A

Rationale: The correct answer is A: 'I will place the client in a private room.' Placing the client in a private room helps prevent the spread of MRSA, a contact precaution. Choice B is incorrect because visitors should be following standard precautions for MRSA, not just wearing a mask within a specific distance. Choice C is incorrect as the gown should be removed before exiting the client's room to prevent the spread of MRSA. Choice D is incorrect as an N95 respirator mask is not typically required for the care of a client with MRSA; standard precautions are usually sufficient.

Correct Answer: A

Rationale: The correct action when checking a client's blood pressure is to apply the cuff above the client's antecubital fossa. Placing the cuff above this area allows for an accurate measurement of blood pressure. Choice B is incorrect because the cuff width should be approximately 40% of the arm circumference, not 60%. Choice C is incorrect as the client's arm should rest at heart level, not above it, to ensure an accurate reading. Choice D is incorrect as the pressure on the client's arm should be released at a rate of 2 to 3 mm per second, not 5 to 6 mm per second.

Correct Answer: B

Rationale: Edema, indicated by 2+ edema of fingers and hands, can impair blood flow and peripheral perfusion, leading to reduced oxygen saturation readings on a pulse oximeter. High blood pressure (choice A) would not directly affect oxygen saturation readings. Radial pulse volume (choice C) and capillary refill time (choice D) are more related to assessing circulation rather than contributing significantly to oxygen saturation readings.

Correct Answer: B

Rationale: Restlessness and increased mucus production are common signs of gastrointestinal issues or reflux in infants, which could explain the symptoms of spitting up and excessive gas. Increased temperature and lethargy (Choice A) are more indicative of an infection rather than gastrointestinal issues. Increased sleeping and listlessness (Choice C) are not typical signs associated with the symptoms described. Diarrhea and poor skin turgor (Choice D) are not directly related to the symptoms of spitting up and gas in this scenario.

Correct Answer: D

Rationale: The correct answer is D: Abdominal mass and weakness. In neuroblastoma, the most common presenting signs are related to the mass effect of the tumor, leading to an abdominal mass and symptoms of weakness. Lymphedema and nerve palsy (Choice A) are not typically associated with neuroblastoma. Hearing loss and ataxia (Choice B) are more indicative of other conditions like neurofibromatosis or brain tumors. Headaches and vomiting (Choice C) are more commonly seen in conditions such as brain tumors or increased intracranial pressure, but they are not specific to neuroblastoma.
