Correct Answer: B

Rationale: The healthcare professional's first action before administering a blood transfusion should be to verify that the client's blood type matches the blood product. This step is crucial to ensure compatibility and prevent potentially severe transfusion reactions. Checking the client's temperature (Choice A) is important but not the first action in this scenario. Administering the blood through an IV push (Choice C) is incorrect as blood transfusions are typically administered as a slow infusion. Ensuring the blood is warmed before administration (Choice D) is not the first action and is not a standard practice in blood transfusions.

Correct Answer: B

Rationale: The axillary method is the most appropriate for newborns because it is non-invasive and safe. Rectal temperature measurement can be uncomfortable and poses a risk of injury, especially in newborns. Oral temperature measurement is not recommended for newborns due to their inability to cooperate and potential inaccuracies. Tympanic temperature measurement may not be as accurate in newborns compared to older children or adults.

Correct Answer: A

Rationale: Low birth weight increases a child's vulnerability to physical maltreatment due to additional care needs. Advanced maternal age (choice B) is not directly linked to an increased risk of physical maltreatment. Single parenthood (choice C) is not a characteristic that inherently increases the risk of physical maltreatment. Premature birth (choice D) is not listed as a characteristic that directly increases a child's risk of physical maltreatment.

Correct Answer: B

Rationale: The correct answer is B: 'Reduce sodium intake to less than 1,500 mg per day.' For clients with hypertension, reducing sodium intake is crucial as it helps manage blood pressure. High sodium intake can lead to fluid retention and increased blood pressure. Choice A is incorrect because increasing sodium intake would worsen hypertension. Choice C is also correct as limiting caffeine intake is beneficial for managing hypertension. Choice D is incorrect as increasing caffeine intake can elevate blood pressure, which is detrimental for clients with hypertension.

Correct Answer: C

Rationale: Choice C is correct because it demonstrates the client's understanding of the procedure, which involves discarding the first urine of the day at the specified time and then saving all subsequent urine for the next 24 hours. Choices A, B, and D do not reflect an understanding of the correct procedure. Choice A is incorrect because bowel movements are not part of a 24-hour urine collection. Choice B is incorrect as it does not specify discarding the first urine. Choice D is incorrect as it mentions filling up the bottle quickly, which is not the correct way to collect a 24-hour urine sample.
