Ordered: Potassium chloride (K-Dur) 60 mEq
Available: Potassium chloride (K-Dur) 20 mEq/15 mL
Administer: _____mL
The Correct Answer is ["45"]
To calculate the amount of potassium chloride (K-Dur) solution to administer, we need to use the following formula:
mL to administer = ordered dose (mEq) / available dose (mEq/mL) x mL
Plugging in the values from the question, we get:
mL to administer = 60 mEq / (20 mEq / 15 mL) x 15 mL
Simplifying the equation, we get:
mL to administer = 60 mEq x 15 mL / 20 mEq
mL to administer = 45 mL
Therefore, the nurse should administer 45 mL of potassium chloride (K-Dur) solution to the patient.

Correct Answer is B
Explanation
A. Redo the initial assessment and document current findings:
This option suggests repeating the entire initial assessment. While reassessment is important, redoing the entire initial assessment may not be necessary. Instead, a focused assessment on the specific area of concern (skin integrity) is more appropriate.
B. Perform and document a focused assessment of skin integrity:
This is the recommended choice. If unexpected findings are observed during care, such as reddened areas over bony prominences, it is important to conduct a focused assessment on the skin to identify any issues and document the findings accurately.
C. Correct the initial assessment form:
Simply correcting the initial assessment form may not address the immediate need for assessing and addressing the reddened areas. It is more crucial to perform a focused assessment on the skin.
D. Conduct and document an emergency assessment:
Reddened areas over bony prominences may not necessarily indicate an emergency. However, addressing the issue promptly is important. A focused assessment would be more appropriate than conducting a full emergency assessment.
Correct Answer is A
Explanation
A. Check temperature and SPO2
When the nurse finds an adult patient's pulse rate to be 140 beats per minute, it is important to assess other vital signs, particularly temperature and oxygen saturation (SPO2). This helps gather additional information to understand the overall clinical picture and assess for potential underlying causes of the elevated heart rate.
B. Report the rate to the primary care provider:
Reporting the heart rate to the primary care provider may be necessary, but it should not be the immediate action. Assessing other vital signs first provides a more comprehensive understanding.
C. Check the pulse again in 2 hours:
Waiting for 2 hours to recheck the pulse is not appropriate when the heart rate is significantly elevated. Immediate action and further assessment are needed.
D. Record the information:
Recording the elevated heart rate is part of documentation, but it should be accompanied by a more comprehensive assessment of vital signs and potential contributing factors.
