A nurse is reviewing laboratory results for a client who is receiving IV furosemide. Which of the following results indicates a therapeutic response to the medication?

Increased calcium level

Decreased urine specific gravity

Decreased liver enzymes

Increased serum sodium level

Answer and Explanation

The Correct Answer is B

A. Increased calcium level: Furosemide is a loop diuretic that promotes the excretion of electrolytes, including calcium. An increased calcium level would not indicate a therapeutic response and may suggest another metabolic issue.

B. Decreased urine specific gravity: Furosemide increases urine output by inhibiting sodium and water reabsorption in the loop of Henle. A decreased urine specific gravity reflects more dilute urine, which indicates effective diuresis and a therapeutic response.

C. Decreased liver enzymes: Furosemide does not have a direct effect on liver enzyme levels. Changes in liver enzymes would not reflect the effectiveness of the diuretic therapy.

D. Increased serum sodium level: Loop diuretics like furosemide can lead to sodium loss rather than an increase. An elevated serum sodium level would not indicate a therapeutic effect of the medication.

Correct Answer is D

Explanation

A. Blood pressure 140/86 mm Hg: This blood pressure is slightly elevated but not indicative of an adverse reaction to morphine. Morphine more commonly causes hypotension rather than hypertension.

B. Heart rate 65/min: A heart rate of 65/min is within normal limits for most adults and does not signal a concerning response to morphine.

C. Temperature 37.5° C (99.5° F): This is a mild elevation within normal limits and is not associated with morphine administration.

D. Respiratory rate 10/min: Morphine can depress the central nervous system, leading to respiratory depression. A respiratory rate of 10/min is below the normal range (12–20/min) and indicates an adverse reaction requiring immediate monitoring and intervention.

A. History of gastrointestinal bleeding B. Liver impairment C. Allergy to codeine D. History of glaucoma

Correct Answer is A

Explanation

A. History of gastrointestinal bleeding: Ketorolac is a nonsteroidal anti-inflammatory drug (NSAID) that can inhibit prostaglandin synthesis, increasing the risk of gastrointestinal bleeding or ulceration. A history of GI bleeding is a contraindication due to the heightened risk of serious complications.

B. Liver impairment: While caution is warranted, mild to moderate liver impairment is not an absolute contraindication. Liver function should be monitored, but it does not automatically prevent ketorolac use.

C. Allergy to codeine: Ketorolac is not an opioid and does not contain codeine. An allergy to codeine does not contraindicate its administration.

D. History of glaucoma: Ketorolac does not typically affect intraocular pressure or exacerbate glaucoma. It is not contraindicated in clients with this condition.
