A nurse is preparing to administer a 2 mg IV bolus of morphine sulfate. Morphine sulfate is available in a concentration of 10 mg/mL. How many mL should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.2"]
- Step 1: Identify the required dose in milligrams (mg). The nurse is scheduled to administer 2 mg of morphine sulfate.
- Step 2: Identify the concentration of the available solution. The available solution contains 10 mg of morphine sulfate per 1 mL.
- Step 3: Calculate the volume of solution needed to deliver the required dose. We can set up a proportion to solve for this:
- 10 mg is to 1 mL as 2 mg is to X mL.
- In other words, 10 mg : 1 mL = 2 mg : X mL.
- Step 4: Solve for X using cross-multiplication and division:
- Cross-multiplication gives us: 10 mg × X mL = 2 mg × 1 mL.
- Simplifying this gives us: 10X = 2.
- Dividing both sides by 10 gives us: X = 2 ÷ 10.
- Calculating the division gives us: X = 0.2.
So, the nurse should administer 0.2 mL of the morphine sulfate solution per dose.

Correct Answer is B
Explanation
Choice A reason:While sharing needles can transmit hepatitis, it is more commonly associated with hepatitis B and C, not hepatitis A.
Choice B reason:Eating shellfish from contaminated water is a well-known route of transmission for hepatitis A, aligning with the client's symptoms.
Choice C reason:Blood transfusions were a risk for hepatitis transmission in the past, but since the 1990s, blood products are screened for hepatitis, making this an unlikely source.
Choice D reason:Unprotected sex can be a route of transmission for hepatitis, but hepatitis A is more commonly spread through ingestion of contaminated food or water, not sexual contact.
Correct Answer is ["A","B","D"]
Explanation
Title: Choice A reason: Beta-blocking agent Beta-blocking agents are often used in the management of cirrhosis of the liver. They are particularly useful in managing portal hypertension, a common complication of cirrhosis. Beta-blockers lower elevated portal pressure and protect against variceal hemorrhage, a serious complication of portal hypertension. Therefore, a beta-blocking agent may be ordered for a client with cirrhosis of the liver.
Title: Choice B reason: Diuretic Diuretics are commonly used in the management of fluid retention, a frequent complication in patients with cirrhosis. Fluid retention can lead to conditions such as ascites (abdominal fluid accumulation) and edema (swelling in the legs, feet, or ankles)2. Diuretics help to remove excess fluid from the body, thereby managing these symptoms. Therefore, a diuretic may be ordered for a client with cirrhosis of the liver.
Title: Choice C reason: Opioid analgesic While opioid analgesics are powerful pain relievers, they should be used with caution in patients with cirrhosis of the liver. Opioids can precipitate hepatic encephalopathy, a condition characterized by altered mental status and neuromuscular dysfunction, which is a serious complication of cirrhosis. Therefore, an opioid analgesic may not be the best choice for a client with cirrhosis of the liver.
Title: Choice D reason: Lactulose Lactulose is a non-absorbable sugar that is widely used in the treatment of hepatic encephalopathy, a common complication in patients with cirrhosis. It works by reducing the absorption of ammonia in the gut, thereby lowering blood ammonia levels and improving symptoms of hepatic encephalopathy. Therefore, lactulose may be ordered for a client with cirrhosis of the liver.
Title: Choice E reason: Sedative Sedatives should be used with caution in patients with cirrhosis of the liver. Like opioids, they can precipitate hepatic encephalopathy. Therefore, a sedative may not be the best choice for a client with cirrhosis of the liver.
