A client is to receive methylprednisolone 6 mg IV push. The medication is available as a vial with 4mg/mL. What volume should the nurse administer?
The Correct Answer is ["1.5"]
Step 1: Identify what is given
Prescribed dose: 6 mg
Available concentration: 4 mg/mL
Step 2: Use the formula
Volume (mL) = Prescribed Dose (mg) ÷ Concentration (mg/mL)
Volume = 6 ÷ 4 = 1.5 mL

Correct Answer is B
Explanation
A. While age is a risk factor for colorectal cancer, the risk typically increases after age 50, not at 35. Most colorectal cancers are diagnosed in individuals over the age of 50, so age over 50 is a more significant risk factor.
B. Ulcerative colitis is a chronic inflammatory bowel disease that increases the risk of developing colorectal cancer, especially after long-term inflammation. The risk increases the longer someone has had ulcerative colitis, particularly if the disease affects a large portion of the colon.
C. A high fiber, low fat diet is actually protective against colorectal cancer. Diets rich in fiber and low in fat have been shown to reduce the risk of developing colorectal cancer by promoting bowel regularity and reducing inflammation in the colon.
D. While having a first-degree relative (parent, sibling, or child) with colorectal cancer is a significant risk factor, having a distant relative (e.g., cousin, aunt, uncle) with the disease does not carry the same increased risk. The genetic risk is more strongly associated with immediate family members.
Correct Answer is A
Explanation
A. Jugular vein distention and +3 peripheral edema are signs of right-sided heart failure, which can result from worsening mitral stenosis. As the mitral valve becomes more narrowed, it leads to increased pressure in the left atrium and eventually backs up into the lungs and right side of the heart, causing fluid retention.
B. An increase in systolic blood pressure by 10 mmHg does not directly indicate worsening mitral stenosis. Blood pressure changes can occur for various reasons but are not as specific as signs of heart failure in this context.
C. Complaints of epigastric pain after eating a large meal are typically related to gastrointestinal issues rather than directly indicating worsening mitral stenosis.
D. Complaints of dyspnea while completing activities of daily living (ADLs) can be a sign of worsening mitral stenosis, but the additional signs of jugular vein distention and edema are more definitive indicators of worsening disease.
