A nurse is assessing a client who has dehydration due to prolonged diarrhea. Which of the following findings should the nurse expect?
Bradycardia
Edema
Hypotension
Crackles
The Correct Answer is C
A. Bradycardia is not expected with dehydration. Instead, tachycardia occurs as a compensatory response to low blood volume.
B. Edema is not a symptom of dehydration. Instead, dehydration leads to decreased tissue perfusion and dry mucous membranes.
C. Hypotension occurs due to decreased blood volume from fluid loss, leading to low blood pressure and potential dizziness or weakness.
D. Crackles are not expected in dehydration. Instead, lung sounds are typically clear unless another condition is present.

C. Measuring urine specific gravity helps assess hydration status and kidney function, which can be affected by acute alcohol toxicity.

Correct Answer is C
Explanation
A. "I will take the medication in the morning." Metformin extended-release can be taken once daily, but it is usually recommended with the evening meal to improve gastrointestinal tolerance.
B. "I will take the medication on an empty stomach." This is incorrect because metformin should be taken with food to reduce gastrointestinal side effects such as nausea and diarrhea.
C. "I will avoid crushing this medication." This is correct because extended-release tablets should not be crushed, split, or chewed, as this can alter the drug’s release mechanism.
D. "I will expect to gain weight." Metformin is not associated with weight gain; in fact, it may cause modest weight loss in some clients.
