Correct Answer: D

Rationale: Administering IV fluids is crucial to address potential dehydration and electrolyte imbalances, especially if the client is unable to provide a clear history. Starting an IV infusion of normal saline will help rehydrate the client and address any electrolyte imbalances, which are common in clients with diabetes experiencing symptoms like abdominal cramping and vomiting. Obtaining a serum potassium level can be important but is not the priority when the client is showing signs of dehydration and confusion. Administering insulin should only be done after addressing hydration and electrolyte status. Assessing pupillary response to light is not the most critical action in this situation compared to addressing dehydration and potential electrolyte imbalances.

Correct Answer: C

Rationale: The correct answer is C: Neurovascular assessment of the lower extremities. After a myelogram, it is crucial to monitor the neurovascular status to detect any signs of complications such as impaired circulation or nerve damage. This assessment helps in identifying early signs of vascular compromise or neurological deficits. Choices A, B, and D are not the priority after a myelogram. Lie-sit-stand blood pressure measurement is not directly related to post-myelogram care. Abdominal assessment and skin assessment are important but not the priority immediately after this procedure.

Correct Answer: B

Rationale: After being submerged in water, the client should be instructed to seek medical care promptly if a fever develops since complications may arise later. Choices A, C, and D are not directly related to the potential complications from submersion in water and are therefore incorrect. Avoiding smoke-filled environments, increasing oral fluids for a productive cough, and scheduling frequent rest periods are not the priority concerns in this scenario.

Correct Answer: B

Rationale: When a client in the intensive care unit is mechanically ventilated, has an indwelling urinary catheter, and is restless, the priority action is to check the urinary catheter for obstruction. Restlessness in this context could be due to a blocked catheter causing discomfort or urinary retention, which needs immediate attention to prevent complications. Reviewing the heart rhythm on cardiac monitors can be important but is not the priority in this scenario. Auscultating bilateral breath sounds is also important in a ventilated client but addressing the potential immediate issue of a blocked catheter takes precedence. Giving a PRN dose of lorazepam should not be the first action without addressing the underlying cause of restlessness.

Correct Answer: D

Rationale: The correct action for the nurse to implement is to consult with the pharmacist regarding the change in prescription. With the high first-pass effect of the medication when given orally, it reduces its bioavailability, meaning a dosage adjustment may be necessary to achieve the desired therapeutic effect. Continuing to administer the medication via the IV route (choice A) is not appropriate as the prescription has been changed to oral administration. Giving half the prescribed oral dose until consulting the provider (choice B) is not recommended without proper guidance, which should come from consulting with the pharmacist. Simply administering the medication orally as prescribed (choice C) without addressing the potential issue of reduced bioavailability may lead to suboptimal treatment outcomes.
