A nurse is caring for a client who has an active upper gastrointestinal bleed. After inserting an NG tube into the client, which of the following findings should the nurse anticipate?
Frothy pink drainage
Greenish-yellow drainage
Dark amber drainage
Coffee-ground drainage
The Correct Answer is D
A. Frothy pink drainage is more characteristic of recent or active bleeding rather than an upper gastrointestinal bleed.
B. Greenish-yellow drainage typically indicates bile or gastric secretions rather than blood.
C. Dark amber drainage might suggest older, degraded blood but is less specific to an active upper GI bleed.
D. Coffee-ground drainage is indicative of older, partially digested blood and is expected in cases of upper gastrointestinal bleeding due to the breakdown of blood in the stomach.

Correct Answer is A
Explanation
A. A decrease in heart rate can indicate adequate fluid resuscitation as it suggests improved circulatory status and reduced compensatory tachycardia, which is a response to hypovolemia.
B. An increase, rather than a decrease, in blood pressure would typically indicate improved fluid status and perfusion following adequate fluid resuscitation.
C. Weight changes are not an immediate indicator of fluid resuscitation adequacy. Weight reflects overall fluid balance over a longer period.
D. An increase, not a decrease, in urine output is expected with adequate fluid resuscitation, as improved renal perfusion results in better urine production.
Correct Answer is C
Explanation
A. The Mantoux test (TB skin test) is used for screening and indicates exposure to TB but cannot confirm active disease.
B. A chest x-ray can show signs suggestive of TB, such as lung lesions, but it does not confirm the presence of the bacteria.
C. A sputum culture for acid-fast bacillus is the most reliable test for confirming active pulmonary TB as it identifies the presence of Mycobacterium tuberculosis in the sputum.
D. A sputum smear can detect acid-fast bacilli but is less definitive than a culture, which confirms the diagnosis.
