A nurse is reinforcing healthy eating habits for an older adult client to ensure adequate dietary intake. Which of the following is an appropriate recommendation?

A. Prepare the client for a barium enema: A barium enema is a diagnostic imaging procedure used to evaluate structural abnormalities in the colon, but it is not the immediate priority when a client on warfarin reports blood in stools. The focus should first be on assessing coagulation status and risk of bleeding.

B. Prepare the client for a colonoscopy: Colonoscopy allows direct visualization of the colon to identify sources of bleeding, but performing an invasive procedure in a client on anticoagulation without assessing clotting parameters first increases the risk of severe hemorrhage. Immediate evaluation of anticoagulation levels is safer.

C. Request an aPTT level: Activated partial thromboplastin time (aPTT) is used to monitor heparin therapy, not warfarin. Checking aPTT would not provide accurate information about the client’s anticoagulation status or bleeding risk with warfarin therapy.

D. Request an INR level: The international normalized ratio (INR) is the standard laboratory test for monitoring warfarin therapy. An elevated INR indicates increased anticoagulation and a higher risk of bleeding. Assessing the INR provides critical information to guide interventions such as dose adjustment or vitamin K administration.

Rationale for correct choices:

• Weight: The child’s weight increased from 9.5 kg on day 2 to 10.2 kg on day 3, surpassing the admission weight of 10 kg. This indicates successful rehydration and restoration of fluid balance. Weight gain is a reliable objective marker of improvement in pediatric dehydration.

• Bowel pattern: The child’s stools changed from six watery stools on day 2 to two formed stools on day 3. This reflects resolution of diarrhea and recovery of gastrointestinal function. Normalization of bowel movements indicates that electrolyte and fluid losses have been addressed effectively.

• Urine specific gravity: Urine specific gravity decreased from 1.031 on admission to 1.018 on day 3. This reflects improved hydration status and kidney perfusion, as urine is less concentrated. Monitoring urine concentration helps evaluate the effectiveness of fluid replacement therapy.

• Skin turgor: Skin turgor improved from 2 seconds to less than 1 second and appears consistent with the child’s baseline. This indicates restored hydration and effective fluid therapy. Normal skin turgor demonstrates recovery from extracellular fluid deficit.

• Heart rate: The heart rate decreased from a tachycardic 116/min on Day 2 to 100/min on Day 3. A stable, lower heart rate indicates that the circulatory volume is adequate and the heart no longer needs to overcompensate for low blood volume.

Rationale for incorrect findings:

• Sodium level: Sodium remained within normal range (138 mEq/L), so while stable, it does not specifically indicate improvement beyond baseline.

• Respiratory rate: Respiratory rate remained mildly elevated at 26 breaths/minute; it shows stability but does not directly indicate recovery from dehydration.
