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 D
Explanation
Choice A rationale:
Continue with the blood pressure assessment. Continuing with the blood pressure assessment without addressing the observed auscultatory gap could lead to an inaccurate reading. It's important to investigate and note the presence of an auscultatory gap before proceeding with the assessment.
Choice B rationale:
Reposition the stethoscope over the brachial artery. Repositioning the stethoscope may not resolve the issue of hearing silence followed by a Korotkoff sound. It is important to assess the situation further before making adjustments.
Choice C rationale:
Reinflate the cuff to a higher number. Reinflating the cuff to a higher number without addressing the auscultatory gap can result in an inaccurate reading. The presence of an auscultatory gap should be noted and managed appropriately.
Choice D rationale:
Note the presence of an auscultatory gap. This is the correct choice. An auscultatory gap is a temporary disappearance of sounds during the blood pressure measurement, and it may indicate underlying cardiovascular issues. The nurse should note its presence, document it, and take appropriate action if necessary.
Correct Answer is C
Explanation
- A radial pulse is the pulse felt at the wrist, where the radial artery runs along the thumb side of the forearm. It is one of the most common sites for measuring a person's heart rate.
- To measure a radial pulse, the examiner should place two or three fingers over the radial artery, just below the wrist crease, and apply gentle pressure until a pulsation is felt. The examiner should not use the thumb, as it has its own pulse and may interfere with the accuracy of the measurement. The examiner should count the number of beats for 15, 30, or 60 seconds, depending on the regularity and rate of the pulse.
- In the picture, the unlicensed assistive personnel (UAP) is using the thumb to measure the radial pulse, which is incorrect. The practical nurse (PN) should demonstrate the correct pulse site to the UAP and explain why using the thumb is not appropriate. This will help to ensure that the UAP obtains an accurate and reliable pulse rate for the client.
Therefore, option C is the correct answer, while options A, B, and D are incorrect.
Option A is incorrect because instructing the UAP to report any abnormal findings does not address the error in technique.
Option B is incorrect because reminding the UAP to check the pulse volume does not address the error in technique.
Option D is incorrect because confirming the accuracy of the pulse rate obtained by the UAP does not address the error in technique.
