Hyperglycemia.

Ketonuria.

Metabolic acidosis.

Hypokalemia.

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 B

Explanation

Choice A rationale:

“I should take this medication with food to prevent stomach upset.” Rationale: This statement is not accurate for fluconazole. While some medications should be taken with food to reduce stomach upset, fluconazole is typically taken on an empty stomach. Taking it with food may reduce its absorption.

Choice B rationale:

“I should avoid drinking alcohol while taking this medication.” Rationale: This is the correct response. Fluconazole can interact with alcohol and may lead to increased side effects or reduced effectiveness of the medication. Therefore, it is essential to avoid alcohol while taking fluconazole.

Choice C rationale:

“I should use a barrier method of contraception while taking this medication.” Rationale: While it is generally a good practice to use barrier contraception during treatment for a fungal infection to prevent potential spread to a partner, this statement does not specifically address fluconazole's requirements or interactions.

Choice D rationale:

“I should stop taking this medication if I develop a rash.” Rationale: This statement is not entirely accurate. While it is important to monitor for skin rashes as they can be a sign of an allergic reaction, the decision to stop taking fluconazole should be made in consultation with a healthcare provider. It is not an automatic response to developing a rash.

A. “You may notice that your reaction time is slower than before.”. B. “You may experience some difficulty with learning new things.”. C. “You may have more neurotransmitters in your brain as you age.”. D. “You may lose some of your sense of smell and taste over time.”. E. “You may have more oxygen delivery to your brain cells as you age.”.

Correct Answer is ["A","B","D"]

Explanation

Choice A rationale:

Slower reaction time is a common age-related change in the neurological system. The processing of sensory information and response time may become slower in older adults due to changes in neural pathways and decreased neurotransmitter activity.

Choice B rationale:

Older adults may experience some difficulty with learning new things due to changes in cognitive function and neural plasticity. This is a common age-related effect on the neurological system.

Choice C rationale:

This statement is incorrect. Older adults typically have fewer neurotransmitters in their brains as they age, which can contribute to cognitive changes and a decline in cognitive function.

Choice D rationale:

Loss of some sense of smell and taste is an age-related change. Older adults may experience a decreased ability to detect and differentiate smells and tastes due to changes in olfactory and gustatory receptors.

Choice E rationale:

This statement is incorrect. Aging does not necessarily lead to an increase in oxygen delivery to brain cells. In fact, there may be a decrease in cerebral blood flow with age in some individuals.
