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 statement is an advantage of peritoneal dialysis compared with hemodialysis?

• A. Protein loss is less extensive.
• B. Dietary limitations are not necessary.
• C. It is easy to learn and safe to perform.
• D. It is needed less frequently than hemodialysis.

Correct answer: C

Rationale: Peritoneal dialysis is generally easier to learn and can be safely performed at home. Although dietary limitations still apply, this method offers greater flexibility in treatment scheduling compared to hemodialysis, which often requires multiple weekly visits to a dialysis center.

3. The nurses caring for a child are concerned about the child’s frequent requests for pain medication. During a team conference, a new nurse suggests they consider administering a placebo instead of the usual pain medication to see how the child responds. The team educates the nurse on why this is not appropriate and bases the decision on what knowledge?

• A. This practice is unjustified and unethical.
• B. This practice is effective in determining whether a child’s pain is real.
• C. The absence of a response to a placebo means the child’s pain has an organic basis.
• D. A positive response to a placebo will not occur if the child’s pain has an organic basis.

Correct answer: A

Rationale: The correct answer is A. The use of placebos without the patient’s consent is unethical and goes against the principles of beneficence and autonomy. Choice B is incorrect because using placebos does not provide reliable information about the presence or severity of the pain; it only indicates the response to the placebo itself. Choice C is wrong as the absence of a response to a placebo does not definitively mean that the child’s pain has an organic basis; there could be various reasons for the lack of response. Choice D is also incorrect as individuals may have a positive response to a placebo even if their pain has a significant organic cause. Therefore, the most appropriate response is A, emphasizing the ethical concerns surrounding the use of placebos without informed consent.

4. What is the primary symptom of congenital diaphragmatic hernia in a newborn?

• A. Cyanosis
• B. Bradycardia
• C. Absent breath sounds
• D. Tachypnea

Correct answer: C

Rationale: Absent breath sounds on the affected side are a primary symptom of congenital diaphragmatic hernia. Cyanosis, bradycardia, and tachypnea may also be present but are not the primary symptom. Cyanosis is a bluish discoloration of the skin due to poor oxygenation, bradycardia is a slower than normal heart rate, and tachypnea is rapid breathing.

5. The nurse is aware that which age group is at risk for childhood injury because of the cognitive characteristic of magical and egocentric thinking?

• A. Preschool
• B. Young school age
• C. Middle school age
• D. Adolescent

Correct answer: A

Rationale: Preschool children are at higher risk for injury due to magical and egocentric thinking, which can lead to misjudgments about their abilities and dangers.
