Hyperglycemia.
Ketonuria.
Metabolic acidosis.
Hypokalemia.
Dehydration.
Kussmaul respirations
Correct Answer : A,B,C,E,F
Choice A rationale:
Hyperglycemia is a key symptom of DKA. It occurs when there is an insufficient amount of insulin in the body to allow glucose to enter cells for use as energy. As a result, the body begins to break down fat for fuel, leading to the production of ketones and causing blood glucose levels to rise1. Normal blood glucose levels are between 4.0 to 6.0 mmol/L when fasting and up to 7.8 mmol/L two hours after eating2.
Choice B rationale:
Ketonuria, or the presence of ketones in the urine, is another symptom of DKA. When the body breaks down fat for energy, ketones are produced. If too many ketones build up in the blood, they can spill over into the urine1.
Choice C rationale:
Metabolic acidosis occurs in DKA due to the accumulation of ketones in the blood. Ketones are acidic, and when they build up in the blood, they cause the blood to become more acidic, leading to metabolic acidosis1.
Choice D rationale:
Hypokalemia is not a symptom of DKA. In fact, patients with DKA often have high potassium levels in their blood at presentation because acidosis causes potassium to move from inside the cells into the bloodstream1. However, during treatment for DKA, when insulin is administered and acidosis is corrected, potassium moves back into the cells and can lead to low potassium levels or hypokalemia1.
Choice E rationale:
Dehydration is a common symptom of DKA. High blood glucose levels lead to increased urination as the body tries to get rid of the excess glucose. This can result in dehydration1.
Choice F rationale:
Kussmaul respirations are a type of hyperventilation that occurs in DKA as the body tries to get rid of excess acids (ketones) through the lungs by breathing rapidly and deeply1.

Correct Answer is C
Explanation
The correct answer is choice C: Ensure that the call bell is easily accessible to the client.
Choice C rationale: Ensuring that the call bell is easily accessible empowers the client to promptly request assistance if needed during the night. This promotes safety and reduces anxiety, as the client can quickly contact the nurse if they experience an urgent need to use the restroom or require any other assistance during the night.
Choice A rationale: Reassuring the client that someone will check on him hourly may provide some comfort, but it does not directly address the client's issue of urinary frequency. Ensuring easy access to the call bell is a more targeted approach to managing the client's needs.
Choice B rationale: Placing fresh water and a glass within reach on the bedside table is a good practice to maintain hydration, but it does not directly address the client's urinary frequency issue.
Choice D rationale: Offering an evening snack and oral care is essential for the client's overall well-being, but it is not directly related to managing the client's urinary frequency at night. The primary focus should be on ensuring that the client can access assistance quickly when needed.
Correct Answer is D
Explanation
Choice A rationale:
Monitoring blood pressure is a general health assessment measure and may not directly contribute to pain relief in a client with migraine headaches. While it's essential to manage blood pressure as part of overall health, this choice does not address the client's specific request for pain relief.
Choice B rationale:
Taking a few days off work may provide some relief from external stressors, but it is not a reliable intervention for migraine pain relief. Migraine management typically involves strategies that directly target headache symptoms.
Choice C rationale:
Learning muscle relaxation techniques can be helpful in managing migraine headaches. Relaxation techniques, such as progressive muscle relaxation, can reduce muscle tension and help alleviate headache symptoms. However, it may not be the highest-priority intervention.
Choice D rationale:
Lying down in a dark, quiet room is the most appropriate intervention for obtaining pain relief from a migraine headache. This approach minimizes sensory stimuli, reduces external factors that may exacerbate the headache, and promotes relaxation. It is a well-established non-pharmaceutical method for managing migraine pain.
