The nurse is preparing to insert a nasogastric tube in a patient who is semiconscious. To determine the needed length of the tube to be inserted, the nurse measures what length?
From the tip of the nose to the xiphoid process of the sternum.
From the earlobe to the xiphoid process of the sternum.
From the tip of the nose to the earlobe to the xiphoid process.
From the tip of the nose to the earlobe.
The Correct Answer is C
Rationale:
A. Measuring only from the nose to the xiphoid process omits the earlobe landmark, leading to inaccurate length.
B. Measuring from the earlobe to the xiphoid process also omits part of the required distance.
C. The correct measurement for NG tube insertion is from the tip of the nose → earlobe → xiphoid process. This ensures the tube is long enough to reach the stomach without being excessively long.
D. Measuring only to the earlobe is incomplete and far too short for gastric placement.

Correct Answer is D
Explanation
Rationale:
A. The infusion should be stopped before withdrawing the catheter to prevent blood leakage.

D. The catheter should be withdrawn quickly and smoothly to minimize discomfort and trauma to the vein.
Correct Answer is C
Explanation
Rationale:
A. Helping the colleague first delays documentation, increasing the risk of forgetting or inaccurately recording the medication.
B. Documentation is the responsibility of the administering nurse; it should not be delegated to the charge nurse.
C. Medication administration must always be documented immediately after giving to ensure accuracy and patient safety, before attending to other tasks.
D. Documentation is never done before administration; it is done right after the drug is given, so this statement is incorrect.
