NRSG 100 Exam 3 V2 | NRSG 100 Fundamentals of
Nursing | Actual Q&A with Rationale (NRSG100
Exam 3) | Ivy Tech
1. A nurse is preparing to administer an intramuscular injection to an adult client. Which of
the following sites is the preferred location for this procedure due to the absence of large
nerves and blood vessels?
A. Ventrogluteal
B. Deltoid
C. Dorsogluteal
D. Vastus lateralis
Correct Answer: A
Explanation: The ventrogluteal site is the preferred site for intramuscular injections in
adults because it is located away from major nerves and blood vessels. The dorsogluteal
site is no longer recommended due to the high risk of sciatic nerve injury. The deltoid site
is only suitable for small volumes of medication, typically 1 mL or less.
2. A nurse is providing discharge teaching to a client regarding the disposal of used insulin
syringes. Which statement by the client indicates an understanding of the teaching?
A. I will throw the needles in the trash after recapping them.
B. I will drop the needles directly into the recycling bin.
,C. I will place the used needles in a puncture-proof container.
D. I will wait until the needle is dull before disposing of it.
Correct Answer: C
Explanation: Puncture-proof containers are essential for the safe disposal of sharps to
prevent accidental needle sticks. Sharps should never be placed in regular trash or
recycling bins to ensure public safety. Recapping needles is generally avoided in the home
setting to minimize the risk of injury.
3. When assessing a pressure injury, the nurse notes that the wound involves full-thickness
skin loss with visible adipose tissue and epibole. Which stage should the nurse document?
A. Stage 2
B. Stage 1
C. Stage 3
D. Stage 4
Correct Answer: C
Explanation: Stage 3 pressure injuries are characterized by full-thickness skin loss where
subcutaneous fat may be visible. Stage 2 involves partial-thickness loss of the dermis, while
Stage 4 involves exposed bone, tendon, or muscle. The presence of epibole, or rolled wound
edges, is a common feature of Stage 3 injuries.
, 4. A nurse is caring for a client who is receiving supplemental oxygen via a nasal cannula at 3
L/min. What is the approximate fraction of inspired oxygen (FiO2) the client is receiving?
A. 32%
B. 28%
C. 24%
D. 36%
Correct Answer: A
Explanation: Room air provides 21% FiO2, and each liter of oxygen via nasal cannula adds
approximately 4% to that value. Therefore, 3 L/min equals 21% + (3 x 4%), resulting in
33% (or approximately 32% depending on the clinical standard used). Understanding
these calculations is vital for monitoring a client’s respiratory status.
5. Which intervention is the most effective way for a nurse to prevent the spread of infection
between clients?
A. Performing hand hygiene before and after client contact.
B. Administering prophylactic antibiotics.
C. Wearing gloves at all times in the room.
D. Changing the linens on every shift.
Correct Answer: A
