Question 1 of 5
An older client has been prescribed casanthranol on a long-term basis to treat constipation. The nurse determines that which laboratory finding is a result of the side/adverse effects of this medication?
Correct Answer: C
Rationale: Hypokalemia can result from long-term use of casanthranol, which is a laxative. The medication stimulates peristalsis and alters fluid and electrolyte transport, thus helping fluid to accumulate in the colon. The normal range for potassium is 3.5 to 5.0 mEq/L (3.5 to 5.0 mmol/L). The normal range for sodium is 135 to 145 mEq/L (135 to 145 mmol/L). The remaining options all suggest normal values.
Question 2 of 5
Your pregnant client has a new order for a medication. What principle should you apply to this new medication?
Correct Answer: A
Rationale: Drugs in FDA pregnancy categories C, D, and X carry risks (potential harm, known harm, or absolute contraindication, respectively) and are generally contraindicated in pregnancy unless benefits outweigh risks.
Question 3 of 5
As the nurse in an ambulatory care area, you see a new client enter with a cane that appears too short for the client. What should you do?
Correct Answer: C
Rationale: Teaching the client about proper cane length (handle at wrist level when arm is relaxed) promotes safe and effective mobility.
Question 4 of 5
What is the expected date of delivery for your pregnant client when her last menstrual period was on 10/20/2016?
Correct Answer: A
Rationale: Using Naegele's rule, add 1 year and 7 days to the first day of the last menstrual period (10/20/2016), then subtract 3 months: 10/20/2016 + 1 year = 10/20/2017, + 7 days = 10/27/2017, - 3 months = 7/27/2017. Adjusting for a standard 40-week gestation, the expected delivery date is approximately 7/7/2017.
Question 5 of 5
A 12-year-old boy has a fractured femur and is immobilized in traction as shown in the fi gure. The nurse should:
Correct Answer: D
Rationale: The traction is set up correctly. Additional weights are not needed. A well-balanced diet with fiber should be offered. A pillow under the leg would negate the effects of the traction. Because the adolescent is positioned this way for an extended period, the nurse can help by fi nding activities that interest the client.
