Nursing Elites

1. 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.

2. What is the purpose of using cimetidine (Tagamet) for gastroesophageal reflux?

• A. The medication reduces gastric acid secretion.
• B. The medication neutralizes the acid in the stomach.
• C. The medication increases the rate of gastric emptying time.
• D. The medication coats the lining of the stomach and esophagus.

Correct answer: A

Rationale: The correct answer is A. Cimetidine (Tagamet) is an H2 receptor antagonist that works by reducing gastric acid secretion. This action helps to decrease the acidity in the stomach, which in turn reduces the symptoms of gastroesophageal reflux. Choice B is incorrect because cimetidine does not neutralize acid but rather decreases its production. Choice C is incorrect as cimetidine does not affect the rate of gastric emptying time. Choice D is incorrect as cimetidine does not coat the lining of the stomach and esophagus but instead works to reduce gastric acid secretion.

3. 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.

4. An infant, age 6 months, has six teeth. The nurse should recognize that this is what?

• A. Normal tooth eruption
• B. Delayed tooth eruption
• C. Unusual and dangerous
• D. Earlier than expected tooth eruption

Correct answer: D

Rationale: Having six teeth at 6 months is earlier than the typical tooth eruption schedule, but it is not unusual or dangerous. It is within the range of normal variations in infant development.

5. The nurse is preparing to assess a 10-month-old infant. He is sitting on his father's lap and appears to be afraid of the nurse and of what might happen next. Which initial actions by the nurse should be most appropriate?

• A. Initiate a game of peek-a-boo.
• B. Ask the infant's father to place the infant on the examination table
• C. Talk softly to the infant while taking him from his father
• D. Undress the infant while he is still sitting on his father’s lap

Correct answer: A

Rationale: Engaging the infant in a familiar game like peek-a-boo can help reduce fear and build rapport before starting the assessment.
