What should the nurse assess the patient for after discontinuing the TPN?

Hypoglycemia.

Hyperthermia.

Flatulence.

Tachycardia.

Answer and Explanation

The Correct Answer is A

Choice A rationale

Abrupt cessation of total parenteral nutrition (TPN) can lead to a rapid decrease in blood glucose levels. While receiving TPN, the body is continuously supplied with glucose. When this external glucose source is suddenly removed, the pancreas may continue to secrete insulin at a rate higher than needed, resulting in hypoglycemia. Signs and symptoms of hypoglycemia include sweating, tremors, confusion, and dizziness.

Choice B rationale

Hyperthermia, or elevated body temperature above the normal range of approximately 36.5°C to 37.5°C (97.7°F to 99.5°F), is not a typical complication following the discontinuation of TPN. Fever is usually associated with infection or inflammation, neither of which are a direct consequence of stopping TPN.

Choice C rationale

Flatulence, or the accumulation of gas in the digestive tract leading to bloating and the passage of gas, is related to dietary intake and digestive processes. Discontinuing TPN, which bypasses the digestive system, would not directly cause an increase in flatulence. In fact, digestive issues might improve once oral or enteral feeding resumes.

Choice D rationale

Tachycardia, an abnormally rapid heart rate (typically defined as above 100 beats per minute in adults), is not a direct physiological consequence of discontinuing TPN. While changes in fluid balance or electrolyte levels (which can occur with TPN but are monitored closely) could indirectly affect heart rate, hypoglycemia is a more immediate and direct risk upon TPN cessation.

Correct Answer is B

Explanation

Choice A rationale

Sublingual medications are designed to be absorbed directly into the bloodstream through the highly vascular mucous membranes under the tongue. Dissolving it in water and administering it through an NG tube would bypass this route, potentially altering the drug's absorption and effectiveness, as it would then be processed through the gastrointestinal system.

Choice B rationale

Administering the medication under the client's tongue ensures that it is absorbed sublingually, bypassing the gastrointestinal tract. This is the intended route for this medication, allowing for rapid absorption and avoiding potential interactions or degradation in the digestive system. The rich blood supply under the tongue facilitates quick entry into systemic circulation.

Choice C rationale

Requesting an oral formulation might be an option if the sublingual route is absolutely contraindicated, but it doesn't address the immediate situation. Oral medications have different absorption rates and may be unsuitable for a client with an NG tube if they have swallowing difficulties or other gastrointestinal issues.

Choice D rationale

Crushing a sublingual medication and administering it through an NG tube is inappropriate. This alters the intended drug delivery mechanism and could lead to unpredictable absorption, potential blockage of the NG tube, and loss of the medication's intended effect. Sublingual formulations are not designed for enteral administration.

A. 1 minute. B. 2 minutes in each quadrant. C. 5 minutes. D. 10 minutes.

Correct Answer is C

Explanation

Choice A rationale

Listening for bowel sounds for only 1 minute in one area is insufficient to determine their presence or absence accurately. Bowel motility and thus bowel sounds can be intermittent, and listening for a brief period might miss infrequent sounds. A more extended auscultation is necessary to assess bowel activity adequately.

Choice B rationale

Listening for 2 minutes in each quadrant totals 8 minutes of auscultation, which is more comprehensive than 1 minute. However, bowel sounds can still be sporadic. A longer duration of listening in at least one quadrant where sounds might be present is needed before concluding they are absent.

Choice C rationale

Auscultating for bowel sounds for a total of 5 minutes (not necessarily 5 minutes in each quadrant, but listening attentively in different areas for a cumulative of 5 minutes) is the generally accepted minimum duration to confidently declare bowel sounds absent, termed "silent bowel sounds.”. This extended listening time increases the likelihood of detecting any intermittent bowel activity.

Choice D rationale

Listening for 10 minutes is even more thorough, but if no bowel sounds are heard after a continuous and attentive 5-minute auscultation, it is generally considered clinically significant for absent bowel sounds. Prolonged auscultation beyond 5 minutes is usually not necessary unless there are specific clinical indications.
