A nurse is assessing a client who has a mechanical bowel obstruction caused by intussusception of the ileum. Which of the following findings should the nurse expect?

High-pitched bowel sounds

Abdominal bruit

Bruising on the flank area

Coffee-ground emesis

Answer and Explanation

The Correct Answer is A

A) High-pitched bowel sounds: High-pitched bowel sounds, also known as "tinkling" sounds, are characteristic of mechanical bowel obstructions. These sounds are created by the intestines as they try to move contents past the obstruction, resulting in increased peristaltic activity. In the case of intussusception, where one segment of the intestine telescopes into another, the obstruction can cause these distinctive high-pitched sounds due to the narrowing of the bowel lumen.

B) Abdominal bruit: An abdominal bruit is a swishing sound heard over the abdomen, usually indicating turbulent blood flow through narrowed arteries. It is commonly associated with vascular conditions such as atherosclerosis or renal artery stenosis. It is not related to bowel obstruction, as bowel sounds in obstruction cases are generally due to changes in peristaltic activity rather than blood flow.

C) Bruising on the flank area: Bruising on the flank area, known as Grey Turner's sign, is typically seen in conditions involving retroperitoneal hemorrhage, such as severe pancreatitis or trauma. It is not a symptom of bowel obstruction. Bowel obstruction symptoms generally relate to the gastrointestinal tract and include abdominal pain, distension, and altered bowel sounds.

D) Coffee-ground emesis: Coffee-ground emesis is vomit that appears like coffee grounds, indicating the presence of partially digested blood. This is a sign of upper gastrointestinal bleeding, often due to peptic ulcers or gastritis. In mechanical bowel obstruction, vomiting is more likely to contain bile (bilious vomiting) and may occur if the obstruction is high in the small intestine. The appearance of coffee-ground emesis is not typical for bowel obstructions and indicates a different type of gastrointestinal issue.

Correct Answer is D

Explanation

A) Decreased magnesium level: Primary aldosteronism typically affects sodium and potassium balance, but it is less likely to cause significant changes in magnesium levels. Therefore, a decreased magnesium level is not the expected electrolyte imbalance in this condition.

B) Decreased total calcium level: Primary aldosteronism does not primarily affect calcium metabolism. While calcium levels could be influenced indirectly, they are not a primary concern in this disorder. Hence, a decreased total calcium level is not expected.

C) Elevated phosphate level: Phosphate levels are generally not directly influenced by aldosterone. Elevated phosphate levels might be seen in other conditions, but they are not characteristic of primary aldosteronism.

D) Elevated sodium level: Primary aldosteronism leads to excess production of aldosterone, which promotes sodium retention by the kidneys. This retention causes elevated sodium levels, resulting in hypernatremia, and contributes to symptoms like frequent urination due to the body's attempt to excrete excess sodium through increased urine production.

A. Positive leukocyte esterase B. Increased pain upon release of abdominal palpation C. WBC 9,500 mm3 D. Pain from flexion of the left thigh when lying on the right side

Correct Answer is B

Explanation

A. Positive leukocyte esterase is a laboratory finding typically identified during a urinalysis to screen for the presence of white blood cells. While this may indicate a urinary tract infection or renal calculi, it is not a diagnostic marker for an inflamed appendix. In appendicitis, the primary biochemical changes are systemic rather than localized to the urinary excretion system. The nurse would not expect this specific finding to confirm a diagnosis of appendiceal inflammation.

B. Increased pain upon the sudden release of deep abdominal palpation is known as rebound tenderness or Blumberg sign. This clinical phenomenon occurs when the parietal peritoneum is irritated due to the inflammatory process of the adjacent appendix. It is one of the most reliable physical examination findings for identifying peritoneal irritation associated with acute appendicitis. The nurse should expect this reaction during the provider's assessment of the right lower quadrant.

C. A white blood cell (WBC) count of 9,500 mm3 falls within the standard physiological reference range for a healthy adult. In a client with acute appendicitis, the nurse would instead expect to see significant leukocytosis, typically exceeding 10,000 to 18,000 mm3. This elevation in the leukocyte count reflects the body's systemic inflammatory response to the localized infection. A normal count like 9,500 mm3 would be atypical for a client with an actively inflamed appendix.

D. Pain from flexion of the left thigh while lying on the right side is not a characteristic sign of appendicitis. The psoas sign, which is associated with appendicitis, involves pain upon extension or flexion of the right thigh, as the appendix sits in the right iliac fossa. Flexing the left thigh does not cause the anatomical tension required to irritate an inflamed appendix. This finding would suggest a different pathology or involve an unaffected anatomical region.
