What is occult blood?
dark black visible blood
bright red visible blood
blood that contains mucus
blood that cannot be seen
The Correct Answer is D
a) Dark black visible blood: Dark, black blood is typically a sign of blood that has been digested, often due to gastrointestinal bleeding, but this is not the definition of occult blood.
b) Bright red visible blood: Bright red blood is usually a sign of recent bleeding, often from hemorrhoids or anal fissures. Occult blood refers to blood that is not visible.
c) Blood that contains mucus: Blood with mucus is not the definition of occult blood. Occult blood refers to blood that is hidden and cannot be seen without further testing.
d) Blood that cannot be seen: Occult blood refers to hidden blood that is not visible to the naked eye but can be detected through specific tests, such as a fecal occult blood test (FOBT).

Correct Answer is D
Explanation
a) High Glucose: A high glucose diet is not typically recommended for patients with hypertension or heart failure, as it may lead to insulin resistance or contribute to obesity, which exacerbates these conditions.
b) Pureed Diet: A pureed diet is typically prescribed for patients with difficulty swallowing, not specifically for those with hypertension or heart failure.
c) High Mineral: A high mineral diet might not be appropriate for patients with hypertension or heart failure, as certain minerals (like sodium) should be restricted.
d) Sodium-restricted diet: A sodium-restricted diet is commonly prescribed for patients with hypertension or heart failure to help control fluid retention and blood pressure. Reducing sodium intake helps manage these conditions effectively.
Correct Answer is B
Explanation
a) Auscultate breath sounds: While auscultating breath sounds may reveal signs of aspiration (e.g., crackles), stopping the feedings is the immediate priority to prevent further aspiration and reduce the risk of complications like aspiration pneumonia.
b) Stop the feedings: The highest priority is to stop the enteral feedings immediately to prevent further aspiration and potential damage to the lungs, followed by further assessments.
c) Obtain a chest x-ray: A chest x-ray can confirm the presence of aspiration or pneumonia but is not the immediate priority. Stopping the feedings is more urgent.
d) Initiate antibiotic therapy: Antibiotics may be needed if aspiration pneumonia is suspected, but they should not be the first intervention. Stopping the feedings and assessing the patient should be done first.
