What are the signs and symptoms of DKA? Select all that apply.
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:
Tetracycline antibiotics can form insoluble complexes with calcium, reducing their absorption when taken together. Therefore, advising the client to continue taking calcium supplements with food while on tetracycline therapy is not recommended as it may decrease the effectiveness of the antibiotic.
Choice B rationale:
The nurse should advise the client to avoid taking calcium supplements while on tetracycline therapy. Calcium-containing products (such as supplements, dairy products, and antacids) should be taken at least 2 hours before or after tetracycline administration to minimize the interference with drug absorption.
Choice C rationale:
Taking calcium supplements with tetracycline, even with plenty of water, can still lead to reduced drug absorption due to the formation of insoluble complexes. Therefore, this advice is not appropriate.
Choice D rationale:
The nurse should recommend that the client take calcium supplements at least 2 hours before or after tetracycline. This approach ensures that the client receives the full therapeutic benefit of the antibiotic while still meeting their calcium needs separately.
Correct Answer is ["A","C","E"]
Explanation
The observation(s) by the nurse that require immediate intervention to reduce the likelihood of harm to this client are:
A. The client’s oxygen saturation level is 85%. This is a sign of hypoxemia, which can lead to tissue hypoxia, organ damage, and cardiac arrest. The nurse should administer oxygen therapy and monitor the client’s respiratory status closely.
C. The client’s heart rate is 110 beats per minute. This is a sign of tachycardia, which can indicate worsening heart failure, dehydration, infection, or anxiety. The nurse should assess the client’s fluid balance, vital signs, and symptoms and report any changes to the physician. The nurse should also administer medications as prescribed to control the heart rate and reduce the cardiac workload.
E. The client’s blood pressure is 160/90 mmHg. This is a sign of hypertension, which can increase the risk of stroke, myocardial infarction, and renal failure. The nurse should administer antihypertensive medications as prescribed and monitor the client’s blood pressure and urine output. The nurse should also educate the client on lifestyle modifications to lower blood pressure, such as reducing salt intake, exercising, and managing stress .
The other observations do not require immediate intervention, but they should be addressed as part of the comprehensive nursing care plan for the client with heart failure and COPD. These include:
B. The client is eating less than half of meals. This can indicate poor appetite, nausea, dyspnea, or fatigue, which can affect the client’s nutritional status and energy level. The nurse should encourage the client to eat small, frequent, and balanced meals that are low in sodium, fat, and cholesterol. The nurse should also provide oral hygiene and offer supplements or enteral feeding if needed .
D. The client is reading a book. This can indicate that the client is coping well with the condition and engaging in leisure activities that promote relaxation and mental health. The nurse should praise the client for this positive behavior and provide emotional support and counseling as needed. The nurse should also teach the client about the signs and symptoms of exacerbation and when to seek medical help .
