Which histologic finding in an affected area of the body suggests the presence of an inflammatory process?

Increase in monocytes and macrophages.

Predominance of megakaryocytes.

Presences of fibroblasts and collagen.

Prevalence of dead neutrophils.

Answer and Explanation

The Correct Answer is A

A. Increase in monocytes and macrophages. Monocytes and macrophages are key immune cells involved in the inflammatory response. Monocytes migrate to the affected tissue, where they differentiate into macrophages and help clear pathogens, dead cells, and debris. Their presence indicates an ongoing or chronic inflammatory process.
B. Predominance of megakaryocytes. Megakaryocytes are large bone marrow cells responsible for platelet production. They are not involved in inflammation and are typically found in the bone marrow, not in inflamed tissues.
C. Presence of fibroblasts and collagen. Fibroblasts and collagen are associated with tissue repair and scar formation rather than active inflammation. Their presence suggests healing and fibrosis rather than an acute inflammatory response.
D. Prevalence of dead neutrophils. Dead neutrophils are a hallmark of pus formation (suppuration) in bacterial infections but do not necessarily indicate ongoing inflammation. Neutrophils are the first responders in acute inflammation, but their presence alone does not define an inflammatory process—the presence of active immune cells like macrophages is more indicative.

Correct Answer is D

Explanation

A. Continues to take a prescribed vitamin D supplement. Vitamin D supplementation is recommended for older adults to support bone health and calcium absorption. This does not require additional follow-up.
B. Usually eats an additional serving of protein-rich foods daily. Adequate protein intake is essential for muscle maintenance and overall health in older adults. This is a positive nutritional habit and does not indicate a concern.
C. Takes 1200 mg of an over-the-counter calcium supplement daily. This is within the recommended daily intake for older adults (1,000-1,200 mg/day) to maintain bone health. Excess calcium intake should be monitored, but this amount alone does not require urgent follow-up.
D. Ate approximately 1,200 calories daily for the past two weeks. Older adults typically need at least 1,500-2,000 calories per day, depending on activity level and health conditions. A prolonged intake of only 1,200 calories per day may indicate malnutrition, unintentional weight loss, or inadequate nutrient intake, requiring further evaluation.

Correct Answer is ["42"]

Explanation

Flowrate(gtt/min) = (Total volume×Drop factor)/Total time

= (500×20)/240

= 1000/240

= 41.67, round off to the nearest whole number

= 42

Thus, the nurse should regulate the infusion at 42 gtt/min.
