Correct Answer: C

Rationale: The correct criterion for diagnosing cognitive impairment in a child is having an IQ of 70 or less. This range is typically used to define cognitive impairment in children. Choice A ('An IQ of 75 or less') is incorrect as the threshold is generally set at 70 or below. Choice B ('Subaverage functioning') is vague and does not specifically address the IQ criterion. Choice D ('Onset before 18') is unrelated to the primary criterion of IQ level used in diagnosing cognitive impairment in children.

Correct Answer: B

Rationale: A temperature increase of 1.5�F (0.8�C) during a blood transfusion is a significant finding that can indicate a transfusion reaction, such as a febrile non-hemolytic reaction, which can progress to more severe reactions. It is crucial to report this immediately to the healthcare provider for further evaluation and intervention. Mild itching and rash (choice A) are common minor reactions to blood transfusions and can be managed appropriately without immediate concern. An increase in heart rate by 10 beats per minute (choice C) is within an acceptable range and may be a normal compensatory response to the transfusion. A slight headache (choice D) is a common complaint and is not typically associated with severe transfusion reactions; thus, it does not require immediate reporting compared to the temperature increase.

Correct Answer: B

Rationale: Oxygen therapy can reduce the hypoxic drive in COPD patients, leading to increased PaCO2 levels while improving oxygenation (PaO2). In this case, the increase in PaO2 and PaCO2 is due to the reduction of the hypoxic drive by the supplemental oxygen. Choice A is incorrect because hyperventilation would lead to decreased PaCO2. Choice C is incorrect as the ABG values do not indicate respiratory alkalosis. Choice D is incorrect as the ABG values do not support metabolic acidosis.

Correct Answer: C

Rationale: The correct way to measure urinary output for an infant with dehydration is by weighing the diaper. Wet diapers are weighed to assess the amount of output accurately. Attaching a urine collecting bag and inserting a catheter are invasive methods not typically used for routine measurement of urinary output in infants. Wringing out the diaper can lead to inaccurate measurements and is not a recommended method for assessing urinary output.

Correct Answer: C

Rationale: The middle-aged female with a broken humerus who is unable to follow commands and is crying requires immediate action. These symptoms indicate a possible head injury or severe emotional distress that need urgent attention. Choice A is not as urgent since a minor laceration can be addressed after more critical cases. Choice B, although having a dislocated shoulder, is stable, as the client is calm. Choice D presents with minor injuries that can wait while more critical cases are addressed.
