The clinical manifestations of pyelonephritis include?
a. Abdominal or suprapubic pain
b. Costovertebral angle tenderness
c. Persistent vomiting
d. Severe dehydration

Appeared in: AIIMS Raipur - 2017 (shift-2)

Explanation

Pyelonephritis is an infection of the upper urinary tract, specifically the kidney parenchyma and renal pelvis.
Its classic presentation involves a triad of fever, flank pain, and nausea/vomiting.
Costovertebral angle (CVA) tenderness is a hallmark physical examination finding, indicating inflammation of the kidney.
Lower urinary tract symptoms like suprapubic pain can also be present as the infection often ascends from the bladder.
Severe dehydration is a potential complication resulting from fever and vomiting, not a primary diagnostic sign.

Option B: This option incorrectly includes severe dehydration (d) as a primary manifestation and excludes abdominal or suprapubic pain (a), which can be present.
Option C: This option incorrectly includes severe dehydration (d) and excludes costovertebral angle tenderness (b), which is a classic sign of pyelonephritis.
Option D: This option incorrectly includes severe dehydration (d) as a primary clinical manifestation. While dehydration can occur, it is a consequence of the other symptoms.

Clinical Relevance

Nursing practice connection: Knowing Clinical manifestations of pyelonephritis helps nurses interpret findings accurately and avoid errors in routine assessment, medication administration, and patient teaching.
Recognizing the signs of pyelonephritis is crucial for nurses to ensure prompt treatment and prevent complications like renal scarring, abscess formation, or sepsis.
Nursing assessment must include checking for CVA tenderness, monitoring vital signs for fever, and assessing for nausea and vomiting.
A key nursing intervention is to obtain a urine sample for culture and sensitivity before administering the first dose of antibiotics, as this guides effective treatment.

How to Approach the Question

First, understand the question is asking for the primary clinical signs ('manifestations') of pyelonephritis.
Recall or look up the pathophysiology: pyelonephritis is an infection of the kidney (upper urinary tract).
Evaluate each statement: a) Abdominal/suprapubic pain (lower UTI symptom, can co-exist), b) CVA tenderness (classic upper UTI sign), c) Vomiting (systemic sign of infection), d) Dehydration (complication/consequence).
Identify the hallmark sign: CVA tenderness (b) is the most specific sign for pyelonephritis among the choices.
Differentiate between a primary manifestation and a complication. Dehydration (d) is a result of the illness, not a direct sign of the kidney infection itself.
Select the option that combines the most accurate and common manifestations, which are (a), (b), and (c).
