Your patient is ordered a loop diuretic at 1000. Which finding below would require you to hold the dose and notify the physician for further orders?

Sodium level 144

Potassium level 1.5 mEq/L

Blood pressure 102/78

Calcium level 9 mg/L

Answer and Explanation

The Correct Answer is B

Loop diuretics, such as furosemide, are known to cause potassium loss as they increase urine output. A potassium level of 1.5 mEq/L indicates severe hypokalemia (low potassium levels), which can be potentially dangerous and lead to various complications, including cardiac arrhythmias.

Hence, it is important to hold the dose of the loop diuretic and notify the physician so that appropriate interventions can be taken to address the low potassium level, such as prescribing potassium supplementation or adjusting the dosage of the loop diuretic.

A sodium level of 144 is within the normal range (135-145 mEq/L) and does not require immediate action.

A blood pressure of 102/78, although it may indicate hypotension, does not necessarily require holding the dose of the loop diuretic unless it is accompanied by other significant symptoms or clinical concerns.

A calcium level of 9 mg/dL falls within the normal range (8.5-10.5 mg/dL) and does not necessitate holding the loop diuretic dose.

Correct Answer is D

Explanation

Chemotherapy is a treatment modality used to target and destroy rapidly dividing cells, including cancer cells. It works by interfering with the cell division process, which is a characteristic of cancer cells. However, it is important to note that chemotherapy drugs can also affect normal, healthy cells in the body that undergo rapid division, such as cells in the bone marrow, hair follicles, and gastrointestinal lining. This is why chemotherapy can be associated with side effects like bone marrow suppression, hair loss, and gastrointestinal disturbances. While the molecular structure of DNA can be altered by certain chemotherapeutic drugs, this explanation is not comprehensive enough to encompass the overall mechanism of action of chemotherapy.

The statement that "cancer cells are susceptible to drug toxins" is partially true, as cancer cells are generally more vulnerable to the cytotoxic effects of chemotherapy drugs compared to normal cells.

Chemotherapy aims to disrupt the division and growth of cancer cells rather than promoting their division.

A. Corticosteroid B. Muscle relaxant C. Narcotic D. Nonsteroidal anti-inflammatory drug (NSAID)

Correct Answer is D

Explanation

Nonsteroidal anti-inflammatory drugs (NSAIDs) are a class of medications commonly used to relieve pain, reduce inflammation, and lower fever. They work by inhibiting the production of prostaglandins, which are substances in the body that play a role in pain and inflammation. Celecoxib specifically belongs to the subclass of NSAIDs known as selective COX-2 inhibitors, which target the enzyme cyclooxygenase-2 (COX-2). By selectively inhibiting COX-2, celecoxib helps to reduce inflammation and pain while potentially minimizing the gastrointestinal side effects associated with traditional non-selective NSAIDs.
