Choice A rationale

Placing the client in a supine position is not recommended during nasogastric tube insertion. The client should be in an upright position, such as sitting up or in a high Fowler’s position, to facilitate the passage of the tube and reduce the risk of aspiration.

Choice B rationale

Withdrawing the tube if the client gags during insertion is not the correct action. Gagging is a common reaction during nasogastric tube insertion. The nurse should pause and allow the client to rest and swallow. The tube should only be withdrawn if the client is unable to breathe or is extremely distressed.

Choice C rationale

Instructing the client to place his chin to his chest and swallow can facilitate the passage of the tube through the esophagus. This position closes off the trachea and opens the esophagus, reducing the risk of the tube entering the trachea.

Choice D rationale

Measuring the tube for insertion from the tip of the nose to the umbilicus is not the correct method. The correct measurement is from the tip of the nose to the earlobe and then down to the xiphoid process of the sternum.

Choice A rationale

Hyperactive reflexes are not typically associated with hypokalemia. Hypokalemia, or low potassium levels in the blood, can cause muscle weakness, fatigue, constipation, and arrhythmia.

Choice B rationale

Extreme thirst is not a typical symptom of hypokalemia. It is more commonly associated with conditions such as diabetes.

Choice C rationale

A weak, irregular pulse is a common symptom of hypokalemia. Low levels of potassium can affect heart function, leading to abnormal heart rhythms.

Choice D rationale

Hyperactive bowel sounds are not typically associated with hypokalemia. In fact, constipation is a common symptom of this condition.
