A major concern for an 86-year-old patient who has been NPO for 8 hours prior to a diagnostic test would be:

hydration status.

nutritional status.

circulatory status.

fatigue.

Answer and Explanation

The Correct Answer is A

A. Hydration status: Older adults are at increased risk of dehydration due to decreased thirst perception and potential underlying conditions. Prolonged NPO status exacerbates this risk.

B. Nutritional status: While important, 8 hours of fasting does not significantly affect nutrition.

C. Circulatory status: This would not typically be affected solely by NPO status unless dehydration becomes severe.

D. Fatigue: Though possible, it is less critical than hydration status.

Correct Answer is D

Explanation

A. Has a Foley catheter in place: Not required for an MRI. Foley catheters made of metal-free materials do not interfere with MRI imaging.

B. Has drunk a liter of fluid: This is not relevant for an MRI, unless specifically indicated for contrast imaging, which is uncommon.

C. Has eaten a meal: Eating or fasting is not typically relevant for MRI procedures unless sedation or contrast media requires it.

D. Is not wearing anything with metal: Metal objects can interfere with the MRI’s magnetic field and pose a safety risk to the patient and equipment. Even small objects like jewelry, piercings, or implanted devices must be addressed to prevent harm.

A. Determining which medications are ineffective against the causative organism. B. Testing anti-infective medications to see which ones are most effective against the causative organism. C. Growing colonies of the causative organism on a culture medium. D. Identifying the causative organism of the infection.

Correct Answer is B

Explanation

A. Determining which medications are ineffective against the causative organism: The test determines both effective and ineffective antibiotics, but the focus is on identifying the most effective ones.

B. Testing anti-infective medications to see which ones are most effective against the causative organism. Sensitivity testing determines which antibiotics are most effective against the specific organism, guiding treatment.

C. Growing colonies of the causative organism on a culture medium: This is part of the culture process, not sensitivity testing.

D. Identifying the causative organism of the infection: This is also part of the culture process, not the sensitivity component.
