Correct Answer: C

Rationale: A temperature of 38.2°C (100.8°F) suggests the possibility of an underlying infection or fever, which should be evaluated before proceeding with the transfusion to prevent complications. Elevated temperature can indicate an immune response to incompatible blood components, increasing the risk of a transfusion reaction. The other vital signs and lab results provided are within acceptable ranges for administering packed RBCs, making choices A, B, and D less likely to cause a delay in the transfusion.

Correct Answer: B

Rationale: Yogurt is the best choice for increasing calcium intake in a client with osteoporosis. It provides around 300-400 mg of calcium per serving, making it an excellent food source for meeting their calcium needs. Broccoli, spinach, and almonds, while nutritious, do not provide as much calcium per serving as yogurt and are not as effective in helping clients with osteoporosis increase their calcium intake.

Correct Answer: D

Rationale: The correct answer is D because transporting a stable child to x-ray is a task that can be safely delegated to an assistive personnel. This task does not require clinical judgment or specialized skills. Choices A, B, and C involve assessments and interventions that require nursing judgment and should be performed by a qualified nurse. Initiating a dietary consult for a toddler involves assessing the child's nutritional needs and must be done by a nurse. Administering a glycerin suppository to a preschool-age child requires medication administration skills and knowledge of appropriate dosages, which are within the nurse's scope of practice. Evaluating gastric residual following intermittent feeding of an adolescent is a clinical assessment that requires interpretation and decision-making based on the findings, making it a nursing responsibility.

Correct Answer: B

Rationale: The correct action for the nurse to take when administering medications to a client with an NG tube for suction who is NPO is to clamp the NG tube for 30 minutes after medication administration. This is done to allow for proper absorption of the medications before resuming suction. Choice A is incorrect because medications should not be mixed with enteral feedings as it may affect the drug's effectiveness. Choice C is incorrect as medications should not be inserted directly into the NG tube without dilution, as this can cause clogging or affect the tube. Choice D is incorrect because connecting the NG tube to continuous suction after medication administration can interfere with the absorption of the medications.

Correct Answer: B

Rationale: The correct answer is B: Prothrombin time (PT). Amoxicillin can potentiate the effects of warfarin, increasing the risk of bleeding. Monitoring the prothrombin time (PT) is crucial in this situation to assess the client's clotting ability. Choices A, C, and D are incorrect because amoxicillin's interaction with warfarin does not directly impact serum potassium, serum sodium, or blood glucose levels.
