,Germanna NSG 100 Exam 3 | Introduction to
Nursing Concepts (2026) Q&A
1. Which of the following is one of the six rights of medication administration?
A) Right diagnosis
B) Right provider
C) Right dose
D) Right hospital
Correct Answer: Right dose
Rationale: The six rights of medication administration are right patient, right drug, right
dose, right route, right time, and right documentation. Right diagnosis, right provider, and
right hospital are not among the standard rights and are distractors that test recognition of
the correct framework.
2. What is the correct angle for administering an intradermal injection?
A) 5–15 degrees
B) 45 degrees
C) 90 degrees
D) 180 degrees
Correct Answer: 5–15 degrees
Rationale: Intradermal injections are administered at a 5–15 degree angle just below the
epidermis, creating a visible wheal. This route is used for TB skin tests and allergy testing. A
45-degree angle is used for subcutaneous injections, and 90 degrees is used for
intramuscular injections.
,3. A nurse is preparing to administer a subcutaneous injection of heparin. Which action is
correct?
A) Massage the site after injection
B) Do not massage the site after injection
C) Aspirate before injecting
D) Use the Z-track technique
Correct Answer: Do not massage the site after injection
Rationale: Massaging the site after a heparin injection can cause hematoma formation
and should be avoided. The Z-track technique is used for intramuscular injections, not
subcutaneous. Aspiration is not recommended for subcutaneous injections.
4. When mixing regular and NPH insulin, which insulin should be drawn up first?
A) NPH insulin
B) Regular insulin
C) Either insulin, as order does not matter
D) Both insulins simultaneously
Correct Answer: Regular insulin
Rationale: When mixing regular (clear) and NPH (cloudy) insulin, the regular insulin is
drawn up first to prevent contamination of the regular vial with the intermediate-acting
insulin. Drawing up NPH first would alter the action of the regular insulin.
5. Which finding indicates that a patient's nasogastric tube is correctly placed for feeding?
A) pH of gastric aspirate is 5.5
, B) pH of gastric aspirate is 7.0
C) pH of gastric aspirate is 7.5
D) pH of gastric aspirate is 8.0
Correct Answer: pH of gastric aspirate is 5.5
Rationale: Gastric contents are acidic with a pH typically between 1 and 5.5. A pH of 5.5
or lower confirms gastric placement. A pH of 6 or higher suggests the tube may be in the
respiratory tract or intestines, and feeding should not be initiated.
6. A patient is receiving a blood transfusion and develops chills, fever, and lower back pain.
What is the priority nursing action?
A) Slow the transfusion rate
B) Stop the transfusion immediately
C) Administer an antipyretic
D) Obtain a urine sample
Correct Answer: Stop the transfusion immediately
Rationale: Chills, fever, and lower back pain are classic signs of an acute hemolytic
transfusion reaction, a life-threatening emergency. The priority is to stop the transfusion
immediately to prevent further hemolysis, maintain IV access with normal saline, and
notify the provider.
7. Which laboratory finding is expected in a patient with fluid volume deficit?
A) Decreased blood urea nitrogen
B) Increased urine specific gravity
C) Decreased serum sodium
