Safe and Effective Care Environment NCLEX RN Questions

1. What is the purpose of MSDS sheets?

A. Contain the ordering information for each piece of equipment in the office.
B. Are required by OSHA to be accessible to all employees of the office.
C. Can be used to treat patients who have been injured in equipment accidents.
D. None of the above.

Correct answer: B

Rationale: MSDS sheets, also known as Materials Safety Data Sheets, are essential documents that provide detailed information about chemicals used in the workplace. They are required by OSHA to be easily accessible to all employees to ensure they have the necessary information to handle chemicals safely. MSDS sheets do not contain ordering information for equipment in the office (Choice A) or serve as a treatment guide for injured patients (Choice C). Therefore, the correct answer is that MSDS sheets are required by OSHA to be accessible to all employees of the office.

2. Which of the following actions is most appropriate for reducing the risk of infection during the post-operative period?

A. Flush the central line with heparin at least every four hours
B. Administer narcotic analgesics as needed
C. Remove the urinary catheter as soon as the client is ambulatory
D. Order a high-protein diet for the client

Correct answer: C

Rationale: The most appropriate action to reduce the risk of infection during the post-operative period is to remove the urinary catheter as soon as the client is ambulatory. Urinary catheters can serve as a source of bacteria, increasing the risk of infection in the bladder or urethra. By removing the catheter promptly once the client is mobile, the risk of infection can be minimized. Option A, flushing the central line with heparin, is not directly related to reducing urinary tract infections. Option B, administering narcotic analgesics as needed, is important for pain management but does not directly address infection prevention. Option D, ordering a high-protein diet, may be beneficial for wound healing but does not specifically target infection risk reduction in the post-operative period.

3. Which technique is correct when assessing the radial pulse of a patient?

A. Palpate for 1 minute if the rhythm is irregular.
B. Palpate for 15 seconds and multiply by 4 if the rhythm is regular.
C. Palpate for 2 full minutes to detect any variation in amplitude.
D. Palpate for 10 seconds and multiply by 6 if the rhythm is regular and the patient has no history of cardiac abnormalities.

Correct answer: A

Rationale: When assessing the radial pulse, if the rhythm is irregular, the pulse should be counted for a full minute to get an accurate representation of the pulse rate. In cases where the rhythm is regular, the recommended technique is to palpate for 15 seconds and then multiply by 4 to calculate the beats per minute. This method is more accurate and efficient for normal or rapid heart rates. Palpating for 30 seconds and multiplying by 2 is not as effective, as any error in counting results in a larger discrepancy in the calculated heart rate. Palpating for 2 full minutes is excessive and not necessary for routine pulse assessment. Palpating for 10 seconds and multiplying by 6 is not a standard technique and may lead to inaccuracies, especially in patients with cardiac abnormalities.

4. Which of these is a correctly stated outcome goal written by the nurse?

A. The client will walk 2 miles daily by March 19
B. The client will understand how to give insulin by discharge
C. The client will regain their former state of health by April 1
D. The client achieve desired mobility by May 7

Correct answer: A

Rationale: Outcome goals should be SMART, i.e., Specific, Measurable, Appropriate, Realistic, and Timely. Option A is the only outcome that has a specific behavior (walks daily), with measurable performance criteria (2 miles), and a time estimate for goal attainment (by March 19). Option B lacks specificity in terms of what 'understand how to give insulin' entails, and the timeline is vague ('by discharge'). Option C is not measurable or specific about what 'regain their former state of health' means. Option D does not provide a specific behavior or measurable criteria for 'desired mobility,' and the timeline is the only element that is time-bound.

5. A client is post-op day #1 after a hemilaminectomy. The nurse removes the dressing as ordered and notes that the incision appears slightly red, with a small amount of serous drainage coming from the site. The edges of the incision are approximated. What is the next action of the nurse?

A. Assist the client to shower as ordered and monitor the site for further changes
B. Instruct the client to lie prone to allow the site to dry
C. Place antibiotic ointment and a sterile dressing over the site
D. Notify the physician for an antibiotic order

Correct answer: A

Rationale: An incision that appears slightly red with a small amount of serous drainage on the first day following surgery is going through a normal healing process. It is important to keep the incision clean. In this case, the nurse should assist the client to shower as ordered to maintain hygiene and monitor for changes in the incision site. Instructing the client to lie prone may not be necessary and could cause discomfort. Applying antibiotic ointment without a specific order is not recommended as it can interfere with the healing process. Notifying the physician for an antibiotic order is premature at this stage since the incision is showing normal signs of healing.
