Dehydration.

Kussmaul respirations

Answer and Explanation

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 D

Explanation

The correct answer isChoice D.

Choice A rationale:

Hypertension is not a contraindication for administering clonidine. In fact, clonidine is often used to treat hypertension.It works by decreasing the levels of certain chemicals in your blood, allowing your blood vessels to relax and your heart to beat more slowly and easily.

Choice B rationale:

An apical heart rate of 72 beats/minute is within the normal range (60-100 beats/minute) and would not be a contraindication for administering clonidine.Clonidine can lower heart rate, so it’s important to monitor heart rate, but a normal heart rate does not preclude its use.

Choice C rationale:

Muscle weakness is not a specific contraindication for the use of clonidine. While muscle weakness can be a side effect of many medications, it is not typically associated with clonidine.However, if a patient was experiencing severe or unusual muscle weakness, it would be important for the healthcare provider to evaluate this symptom.

Choice D rationale:

A blood pressure of 90/76 mm Hg could be a contraindication for the use of clonidine. Clonidine is a medication that is used to lower blood pressure, and if a patient’s blood pressure is already low, further lowering it could lead to symptoms such as dizziness, fainting, or even shock.Therefore, it would be important to monitor the patient’s blood pressure closely while they are taking this medication.

A. Obtain a urine specimen for analysis. B. Administer a prescribed opioid analgesic. C. Strain the urine for the presence of stones. D. Prepare the client for a prescribed computed tomography (CT) scan. E. Prepare the client for a prescribed computed tomography (CT) scan.

Correct Answer is B

Explanation

Choice A rationale:

Obtaining a urine specimen for analysis is an important step in the assessment of the client with renal calculi. However, it is not the most immediate intervention when the client is experiencing severe flank pain and hematuria. Pain management should take precedence.

Choice B rationale:

This is the correct answer. Severe flank pain in a client with renal calculi is indicative of renal colic, which is typically excruciating. Administering a prescribed opioid analgesic is the priority to relieve the client's pain and distress.

Choice C rationale:

Straining the urine for the presence of stones is an essential nursing intervention to identify and collect any passed stones. However, it is not the most immediate action when the client is in severe pain. Pain management is the priority.

Choice D rationale:

Preparing the client for a prescribed computed tomography (CT) scan is an important diagnostic step to assess the location and size of the renal calculi. However, it is not the most immediate intervention when the client is in severe pain and distress. Pain management should come first.
