Correct Answer is A
Explanation
A. Monitor weight daily: Daily weight monitoring is a crucial aspect of assessing fluid balance in clients with heart failure. Sudden weight gain can indicate fluid retention, which may be a sign of worsening heart failure. The nurse should instruct the client to weigh themselves at the same time each day, preferably in the morning after emptying the bladder and before eating breakfast, and to report any significant weight changes to their healthcare provider.
B. Assess radial pulses daily: While assessing radial pulses is important for monitoring cardiovascular status, it is not specifically focused on assessing fluid balance in heart failure. Radial pulse assessment is more related to evaluating cardiac output and peripheral perfusion.
C. Monitor bowel movements: Monitoring bowel movements is not directly related to assessing fluid balance in heart failure. Although changes in bowel habits can sometimes be associated with fluid and electrolyte imbalances, it is not the primary method for assessing fluid balance in this context.
D. Monitor blood pressure daily: While monitoring blood pressure is important for managing hypertension and evaluating cardiovascular status, it is not specifically focused on assessing fluid balance in heart failure. Blood pressure monitoring is more related to assessing hemodynamic stability and response to medications.
Correct Answer is ["0.8"]
Explanation
To calculate the volume of heparin to administer subcutaneously, you can use the following formula:
Volume (mL) = Desired dose (units) / Concentration (units/mL)
In this case:
Desired dose = 3,800 units
Concentration = 5,000 units/mL
Volume (mL) = 3,800 units / 5,000 units/mL ≈ 0.76 mL
Rounded to the nearest tenth, the nurse should administer approximately 0.8 mL of heparin subcutaneously daily.
