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","C","E","F"]
Explanation
Choice A: Hypokalemia, or low potassium levels in the blood, is not typically associated with CKD. In fact, patients with advanced CKD are more likely to experience hyperkalemia, which is an elevated potassium level, due to the kidneys’ decreased ability to excrete potassium. The normal range for serum potassium is 3.5 to 5.0 mmol/L.
Choice B: Anemia is a common finding in CKD and is due to the kidneys’ reduced production of erythropoietin, a hormone that stimulates the bone marrow to produce red blood cells. Symptoms of anemia include fatigue, weakness, and pale skin. The normal range for hemoglobin in adults is 13.8 to 17.2 grams per deciliter for men and 12.1 to 15.1 grams per deciliter for women.
Choice C: Hypertension, or high blood pressure, is both a cause and a complication of CKD. The kidneys play a crucial role in regulating blood pressure, and as their function declines, hypertension becomes more common. The normal range for blood pressure is typically considered to be 120/80 mmHg.
Choice D: Crackles in the lungs Crackles in the lungs are not a direct manifestation of CKD, but they can occur if the condition leads to fluid overload and heart failure, resulting in pulmonary edema. This is a secondary complication rather than a direct symptom of CKD.
Choice E: Lethargy and a general feeling of malaise are common in CKD due to the buildup of toxins and waste products in the blood that the kidneys can no longer effectively filter out. This can also lead to decreased mental sharpness and a reduced quality of life.
Choice F: Proteinuria, or the presence of excess protein in the urine, is a hallmark sign of CKD. It indicates damage to the kidneys’ filtering units, allowing protein that would normally be retained to leak into the urine. Persistent proteinuria is a sign of chronic kidney damage.
Correct Answer is ["60"]
Explanation
- Step 1: Identify the required dose in grams. The client is scheduled to receive 30 grams of lactulose.
- Step 2: Identify the concentration of the available solution. The available solution contains 5 grams of lactulose per 10 mL.
- Step 3: Calculate the volume of solution needed to deliver the required dose. We can set up a proportion to solve for this:
- 5 grams is to 10 mL as 30 grams is to X mL.
- In other words, 5 g : 10 mL = 30 g : X mL.
- Step 4: Solve for X using cross-multiplication and division:
- Cross-multiplication gives us: 5 g × X mL = 30 g × 10 mL.
- Simplifying this gives us: 5X = 300.
- Dividing both sides by 5 gives us: X = 300 ÷ 5.
- Calculating the division gives us: X = 60.
60 mL of the lactulose solution should be poured into the medication cup to administer the required dose of 30 grams.
