All of the following can influence and can affect the flow rate of a manual (gravity) IV EXCEPT:

A.

Patient's position of their forearm

B.

Height of the IV bag/container

C.

Relationship of size of angiocath to vein

D.

Patient's weight and height

Answer and Explanation

The Correct Answer is D

Rationale:
A. The position of the forearm can affect flow if the IV site becomes kinked or compressed.
B. The height of the IV bag/container directly affects gravity flow—the higher the bag, the faster the flow.
C. The relationship of angiocath size to the vein can influence resistance and flow rate.
D. The patient’s weight and height do not affect the gravity flow rate of an IV infusion, making this the correct exception.

Correct Answer is A

Explanation

Rationale:
A. Tracheal suctioning is the most appropriate intervention for a patient with a tracheostomy and thick, tenacious secretions. It directly clears the airway through the tracheostomy tube.
B. Nasotracheal suctioning is used for patients without a tracheostomy to access the lower airway through the nasal passage.
C. Orotracheal suctioning is also intended for patients without a tracheostomy and is more invasive.
D. Oropharyngeal suctioning clears secretions from the mouth and throat only, not the trachea, and is insufficient for maintaining a tracheostomy airway.

Correct Answer is C

Explanation

Rationale:
A. The unit manager is not responsible for interpreting prescriber orders and should not be relied upon for this task.
B. The unit secretary is not qualified to interpret medical orders.
C. The nurse must call the prescriber directly to clarify any unclear or illegible order. Administering medication without a clear order is unsafe and could result in serious errors.
D. Pharmacists can clarify medication details but cannot interpret illegible handwriting; the prescriber must provide clarification.
