A nurse is reviewing the medication history of a client. The nurse should identify that which of the following medications places the client at risk for hypokalemia?

Acyclovir 400 mg PO twice daily

Furosemide 80 mg PO daily

Cimetidine 300 mg PO four times per day

Meloxicam 5 mg PO once daily

Answer and Explanation

The Correct Answer is B

Furosemide is a loop diuretic commonly prescribed for conditions such as hypertension and edema. One of the side effects of furosemide is the increased excretion of potassium in the urine, which can lead to low potassium levels in the body, known as hypokalemia. The other medications mentioned do not typically place the client at risk for hypokalemia: Acyclovir 400 mg PO twice daily: Acyclovir is an antiviral medication used to treat viral infections, such as herpes. It does not have a direct effect on potassium levels. Cimetidine 300 mg PO four times per day: Cimetidine is a histamine H2 receptor antagonist commonly used to reduce stomach acid production. It does not have a direct effect on potassium levels.

Meloxicam 5 mg PO once daily: Meloxicam is a nonsteroidal anti-inflammatory drug (NSAID) used for pain relief. It does not have a direct effect on potassium levels.

Correct Answer is A

Explanation

The purpose of the stool guaiac test, also known as the fecal occult blood test (FOBT), is to identify the presence of hidden or occult blood in the stool. This test is commonly performed to screen for gastrointestinal bleeding, which can indicate various conditions such as colorectal cancer, ulcers, polyps, or other sources of bleeding in the digestive tract.

The other options mentioned are not specifically detected by the stool guaiac test:

Parasites: The stool guaiac test does not directly detect parasites in the feces. Parasite testing requires a different type of analysis, such as microscopic examination or specialized laboratory tests.

Bacteria: The stool guaiac test does not specifically detect bacteria in the feces. If a bacterial infection is suspected, other diagnostic tests such as stool culture or polymerase chain reaction (PCR) may be ordered.

Fat: The stool guaiac test is not designed to detect fat in the feces. If there is a concern about fat malabsorption, other tests such as fecal fat analysis or Sudan stain may be used.

Correct Answer is ["14"]

Explanation

To calculate the infusion rate in drops per minute (gtt/min), we can use the following formula: Infusion rate (gtt/min) = (Volume to be infused (ml) * Drop factor) / Time (min) Given:

Volume to be infused: 1000 ml

Drop factor: 10 gtt/ml

Time: 12 hr

First, we need to convert the time from hours to minutes:

12 hr * 60 min/hr = 720 min

Now, we can calculate the infusion rate:

Infusion rate (gtt/min) = (1000 ml * 10 gtt/ml) / 720 min

Simplifying the equation:

Infusion rate (gtt/min) = 10000 gtt / 720 min

Dividing both sides:

Infusion rate (gtt/min) ≈ 13.89 gtt/min

Rounding the answer to the nearest whole number, the nurse should set the manual IV infusion to deliver approximately 14 gtt/min.
