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 A
Explanation
Choice A reason: A 12-lead ECG can reveal changes in the ST segment, T wave, and QRS complex, which are indicative of myocardial ischemia, injury, or infarction. It is the first line diagnostic test that needs to be recorded within 10 minutes after the first medical contact in cases of suspected acute coronary syndromes.
Choice B reason: While pain radiating to the left arm can be a symptom of MI, it is not a definitive diagnostic action. It is a common symptom but can also be associated with other conditions.
Choice C reason: Checking the client's blood pressure is important in the overall assessment of the client's cardiovascular status but does not specifically diagnose MI. Blood pressure can be normal, elevated, or decreased in the case of MI.
Choice D reason: Auscultating heart tones can provide information about the presence of murmurs, gallops, or rubs, but it is not a specific diagnostic action for MI. Heart sounds may be normal during an MI.
Correct Answer is A
Explanation
Choice A reason: Frequent nosebleeds and bruising are indicative of coagulopathy, a common complication in advanced cirrhosis due to the liver's impaired ability to synthesize clotting factors. This can lead to an increased tendency to bleed.
Choice B reason: Urinary retention is not typically associated with cirrhosis. Instead, cirrhosis can lead to renal dysfunction known as hepatorenal syndrome, characterized by the failure of the kidneys to filter waste from the blood².
Choice C reason: While constipation can occur in cirrhosis, no bowel movement in three days is not a direct complication of cirrhosis. However, it could be related to the overall health status of the patient or medications used.
Choice D reason: Increased blood glucose is not a direct complication of cirrhosis. Cirrhosis primarily affects the metabolism of proteins and fats and does not directly cause hyperglycemia unless there is concurrent diabetes or metabolic syndrome.
