NHI Patient Care and Procedures 3 — Questions and Answers
Question 1: A patient receiving oxygen via nasal cannula at 4 L/min is most likely receiving approximately what FiO2?
- 21%
- 36% (Correct answer)
- 50%
- 60%
Correct answer: 36%
Each liter per minute of nasal cannula flow increases FiO2 by approximately 4%, so 4 L/min delivers roughly 36% FiO2.
Question 2: When applying compression stockings, the healthcare worker should:
- Apply after the patient has been standing for 30 minutes
- Apply while the patient is supine before getting up (Correct answer)
- Apply only to the affected leg
- Pull stocking over toes only
Correct answer: Apply while the patient is supine before getting up
Compression stockings should be applied while the patient is supine to prevent blood from pooling in the legs before application.
Question 3: A patient states they are allergic to latex. Which gloves should the healthcare worker use?
- Vinyl gloves only (Correct answer)
- Thin latex gloves
- Double latex gloves
- Any glove since allergies are patient-specific
Correct answer: Vinyl gloves only
Vinyl or nitrile gloves must be used for latex-allergic patients to prevent an allergic reaction during care.
Question 4: The normal range for adult respiratory rate at rest is:
- 6-10 breaths/min
- 12-20 breaths/min (Correct answer)
- 22-28 breaths/min
- 30-36 breaths/min
Correct answer: 12-20 breaths/min
A normal adult respiratory rate at rest is 12-20 breaths per minute; rates outside this range are considered abnormal.
Question 5: Which action correctly demonstrates standard precautions for handling soiled linen?
- Shake linen to remove debris before placing in hamper
- Hold linen close to the body while carrying
- Roll linen inward and place directly into the hamper (Correct answer)
- Place soiled linen on the floor temporarily
Correct answer: Roll linen inward and place directly into the hamper
Soiled linen should be rolled inward (soiled side in) and placed directly into the laundry hamper to contain microorganisms.
Question 6: A patient's radial pulse is irregular. What is the best next action?
- Count only for 15 seconds and multiply by 4
- Document as normal
- Count for a full 60 seconds and report to the nurse (Correct answer)
- Recheck in 4 hours
Correct answer: Count for a full 60 seconds and report to the nurse
An irregular pulse should be counted for a full 60 seconds to obtain the most accurate rate and reported to the supervising nurse.
Question 7: Which patient position is used for a rectal examination or enema administration?
- Supine
- Fowler's
- Sim's (left lateral) (Correct answer)
- Trendelenburg
Correct answer: Sim's (left lateral)
Sim's position (left lateral with right knee flexed) aligns the sigmoid colon and is the standard position for enema and rectal procedures.
