During an initial assessment of a client, a nurse notices a discrepancy between the client's current IV infusion and the information received during the shift report. Which of the following actions should the nurse take?

Correct Answer: B

Rationale: The correct action for the nurse to take when noticing a discrepancy between the client's current IV infusion and the information received during the shift report is to compare the current infusion with the prescription in the client's medication record. This step is crucial to ensure the accuracy of the prescribed treatment and to prevent any potential harm to the client. Option A is incorrect because completing an incident report should only be done after verifying the discrepancy. Option C is incorrect as contacting the charge nurse should come after confirming the details. Option D is incorrect as submitting a written warning is not appropriate without verifying the information first.

Correct Answer: B

Rationale: Tingling and numbness in the hands can indicate hypocalcemia, a common complication following a thyroidectomy. Hypocalcemia requires immediate intervention to prevent severe complications like tetany and seizures. Calcium gluconate is the drug of choice for rapidly raising serum calcium levels in hypocalcemic patients. Sodium bicarbonate is not indicated for treating hypocalcemia or related symptoms. Potassium chloride is used to correct potassium imbalances, not calcium. Magnesium sulfate is not the appropriate treatment for hypocalcemia; it is commonly used for conditions like preeclampsia or eclampsia.

Correct Answer: A

Rationale: The correct answer is A: Decerebrate posturing. Decerebrate posturing is an abnormal body posture characterized by rigid extension of the arms and legs, which indicates severe brainstem injury affecting the midbrain and pons. This posture suggests dysfunction or damage to neural pathways controlling muscle tone. Choice B, hypervigilance, is not typically associated with brainstem injury but rather with increased alertness and arousal. Choice C, absence of deep tendon reflexes, is not a specific finding related to brainstem injury. Choice D, a Glasgow Coma Scale score of 15, indicates a fully awake and alert state, which is not expected in a client with a brainstem injury.

Correct Answer: C

Rationale: Placing a pillow between the legs is essential post-total hip arthroplasty to prevent adduction of the hip joint, reducing the risk of dislocation. Choices A, B, and D are incorrect. Using a walker while walking is encouraged for support and stability. Keeping the hip flexed at 90° while sitting can increase the risk of hip dislocation. Crossing legs at the ankles when sitting may also lead to hip dislocation.
