Nursing Elites

1. The nurse suspects that a child has ingested some type of poison. What clinical manifestation would be most suggestive that the poison was a corrosive product?

• A. Tinnitus
• B. Disorientation
• C. Stupor, lethargy, and coma
• D. Edema of the lips, tongue, and pharynx

Correct answer: D

Rationale: Edema of the lips, tongue, and pharynx is a characteristic sign of corrosive poisoning, indicating damage to mucous membranes from ingestion of a caustic substance. Other symptoms may vary depending on the poison but are not as specific to corrosive ingestion.

2. What is the most common cause of bronchiolitis in infants?

• A. Adenovirus
• B. Influenza virus
• C. Respiratory syncytial virus
• D. Parainfluenza virus

Correct answer: C

Rationale: The correct answer is C, Respiratory syncytial virus (RSV). RSV is the leading cause of bronchiolitis, a common respiratory condition in infants that results in inflammation of the small airways in the lung. It is highly contagious and can cause severe respiratory distress in young children, particularly those under 2 years old. Choice A, Adenovirus, is not the most common cause of bronchiolitis in infants. Choice B, Influenza virus, may cause respiratory infections but is not the primary cause of bronchiolitis. Choice D, Parainfluenza virus, can cause croup and other upper respiratory infections but is not the main cause of bronchiolitis in infants.

3. Physiologically, the child compensates for fluid volume losses by which mechanism?

• A. Inhibition of aldosterone secretion
• B. Hemoconcentration to reduce cardiac workload
• C. Fluid shift from interstitial space to intravascular space
• D. Vasodilation of peripheral arterioles to increase perfusion

Correct answer: C

Rationale: In response to dehydration, the body compensates by shifting fluids from the interstitial spaces to the intravascular space to maintain blood pressure and perfusion to vital organs. Hemoconcentration and vasoconstriction are other compensatory mechanisms but are less immediate.

4. An infant has been diagnosed with bladder obstruction. What do symptoms of this disorder include?

• A. Renal colic
• B. Strong urinary stream
• C. Urinary tract infections
• D. Post urination dribbling

Correct answer: D

Rationale: Post-urination dribbling is a symptom of bladder obstruction due to the incomplete emptying of the bladder. A strong urinary stream is typically absent in such cases. UTIs are common, but dribbling is more directly related to the obstruction.

5. For minimal change nephrotic syndrome (MCNS), prednisone is effective when what occurs?

• A. Appetite increases and blood pressure is normal
• B. Urinary tract infection is gone and edema subsides
• C. Generalized edema subsides and blood pressure is normal
• D. Diuresis occurs as urinary protein excretion diminishes

Correct answer: D

Rationale: The effectiveness of prednisone in treating MCNS is indicated by diuresis and a decrease in urinary protein excretion. Subsidence of generalized edema is also a positive sign, but the key indicator is the reduction in proteinuria, which is achieved through diuresis.
