Melena, the passage of black, tarry stools, suggests bleeding from which source?
- A. The perianal or rectal area
- B. The upper gastrointestinal (GI) tract
- C. The lower GI tract
- D. Hemorrhoids or anal fissures
Correct Answer: B
Rationale: Melena indicates bleeding from the upper GI tract. The black, tarry appearance of the stool results from the partial digestion of blood as it passes through the intestines, typically originating from sources like the stomach or duodenum. Lower GI bleeding usually presents as bright red blood in the stool, originating from sources like the colon or rectum. Choices A, C, and D are incorrect because melena specifically points to upper GI bleeding rather than issues in the perianal/rectal area, lower GI tract, or hemorrhoids/anal fissures.

What is the first-line treatment for a febrile seizure in a child?
- A. Antipyretics
- B. Anticonvulsants
- C. Cooling blankets
- D. IV fluids
Correct Answer: A
Rationale: The correct answer is Antipyretics. Febrile seizures in children are usually associated with fever. The first-line treatment aims to reduce fever, which can help prevent febrile seizures. Antipyretics like acetaminophen or ibuprofen are commonly used for this purpose. Anticonvulsants, while used for treating seizures, are not typically the first-line treatment for febrile seizures as they are usually self-limited and resolve on their own. Cooling blankets can be used to lower body temperature in cases of hyperthermia but are not the primary treatment for febrile seizures. IV fluids may be administered in cases of dehydration due to fever or if the child cannot tolerate oral intake, but they are not the first-line treatment for febrile seizures.
A child with acute gastrointestinal bleeding is admitted to the hospital. The nurse observes which sign or symptom as an early manifestation of shock?
- A. Restlessness
- B. Rapid capillary refill
- C. Increased temperature
- D. Increased blood pressure
Correct Answer: A
Rationale: Restlessness is an early sign of shock due to decreased perfusion and oxygenation to the brain. This symptom requires immediate attention to prevent the progression to more severe stages of shock. Rapid capillary refill (Choice B) is not typically an early sign of shock but rather a sign of adequate perfusion. Increased temperature (Choice C) may occur in later stages of shock due to the body's response to stress. Increased blood pressure (Choice D) is not an early sign of shock; in fact, blood pressure tends to decrease in shock as a compensatory mechanism.
Which immunization is typically administered at birth?
- A. Hepatitis B
- B. DTaP
- C. MMR
- D. Varicella
Correct Answer: A
Rationale: The correct answer is A, Hepatitis B. The Hepatitis B vaccine is usually given at birth to protect against hepatitis B, a virus that can lead to chronic liver disease and liver cancer. This vaccination is crucial for newborns, especially those born to mothers who are carriers of hepatitis B. Choices B, C, and D are incorrect because DTaP (B), MMR (C), and Varicella (D) vaccines are not typically administered at birth. DTaP is given in a series starting at 2 months, MMR is usually given around 12-15 months, and Varicella is given between 12-15 months of age.
The nurse is preparing to admit a 6-month-old child with gastroesophageal reflux disease. What clinical manifestations should the nurse expect to observe?
- A. Spitting up
- B. Bilious vomiting
- C. Failure to thrive
- D. All of the above
Correct Answer: D
Rationale: The correct answer is D, as gastroesophageal reflux disease (GERD) in infants typically presents with symptoms such as spitting up, failure to thrive, excessive crying, and respiratory problems due to aspiration. Bilious vomiting is not a common symptom of GERD in infants and may indicate a different or more severe condition, such as intestinal obstruction or other gastrointestinal issues. Therefore, choices A, B, and C are all expected clinical manifestations of GERD in a 6-month-old child, making option D the correct answer.
What intervention is contraindicated in a suspected case of appendicitis?
- A. Enemas
- B. Palpating the abdomen
- C. Administration of antibiotics
- D. Administration of antipyretics for fever
Correct Answer: A
Rationale: Enemas are contraindicated in cases of suspected appendicitis because they can increase the risk of perforation. The pressure from the enema can exacerbate inflammation and potentially lead to the rupture of the appendix. Palpating the abdomen gently is essential for diagnosing appendicitis, as it helps identify the characteristic signs like rebound tenderness. Antibiotics are commonly used to treat the infection associated with appendicitis, and antipyretics are administered to manage fever, which is a common symptom of the condition. Therefore, enemas are the intervention to avoid in suspected appendicitis cases.
