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: “I have a tight sensation in my lower leg when I forget to put my feet up.” This statement may indicate the presence of edema, which is common in cirrhosis due to hypoalbuminemia and sodium retention. However, it is not as immediately concerning as other symptoms because it can often be managed with diuretics and compression. It is important to monitor for worsening edema, as it can lead to increased discomfort and risk of skin breakdown.
Choice B: “I can’t button my pants anymore because my belly is so swollen.” This statement is concerning because it suggests the development of ascites, which is the accumulation of fluid in the peritoneal cavity, causing abdominal swelling. Ascites can lead to abdominal discomfort, difficulty breathing, and is a sign of advanced liver disease with significant portal hypertension. It requires medical evaluation and management, which may include paracentesis (removal of fluid), diuretics, and sodium restriction. Cirrhosis is a late stage of scarring (fibrosis) of the liver caused by many forms of liver diseases and conditions, such as hepatitis and chronic alcoholism. Portal hypertension is an increase in the blood pressure within a system of veins called the portal venous system. Veins from the stomach, intestine, spleen, and pancreas merge into the portal vein, which then branches into smaller vessels and travels through the liver.
Choice C: “I’m very constipated and have been straining during bowel movements.” While constipation is uncomfortable and can indicate dietary issues or side effects from medication, it is not typically a direct complication of cirrhosis or portal hypertension. However, straining during bowel movements can increase the risk of bleeding from esophageal varices if they are present, so it is important to manage constipation to prevent potential complications.
Choice D: “When I sleep, I have to sit in a recliner so that I can breathe more easily.” This statement indicates orthopnea, which can be associated with ascites or pleural effusions (fluid in the lungs), both of which can occur in the setting of cirrhosis and portal hypertension. While this symptom is concerning and affects the client’s quality of life, it is generally less concerning than the development of ascites, as it can be managed with adjustments in sleeping position and medical management of the underlying fluid accumulation.
Correct Answer is A
Explanation
Choice A reason:Pain that is relieved by food intake is a classic symptom of duodenal ulcers, as eating can neutralize stomach acid temporarily, providing relief.
Choice B reason:Pain radiating down the right arm is not a typical symptom of a duodenal ulcer; it is more commonly associated with cardiac issues.
Choice C reason:Nausea and vomiting can be associated with duodenal ulcers, but they are not as specific as pain relief by food intake.
Choice D reason:Weight loss can occur with duodenal ulcers due to pain and eating avoidance, but the key symptom that relates directly to the ulcer is pain relief after food intake.
