Nursing Elites

1. Which of the following can cause coup-contrecoup injuries?

• A. Rotational forces
• B. Deformation forces
• C. Deceleration forces
• D. Acceleration forces

Correct answer: C

Rationale: Deceleration forces occur when the head is moving and abruptly comes to a stop, such as in a car crash. This sudden deceleration can cause the brain to hit against the skull, resulting in coup-contrecoup injuries. In a coup-contrecoup injury, the brain is damaged on opposite sides due to the initial impact and the rebound effect inside the skull. Rotational forces usually result in diffuse axonal injuries rather than coup-contrecoup injuries. Deformation forces can cause focal brain injuries but not coup-contrecoup injuries. Acceleration forces typically lead to diffuse brain injuries, not coup-contrecoup injuries. Therefore, the correct answer is deceleration forces.

2. While working with an obese adolescent, it is important for the nurse to recognize that obesity in adolescents is most often associated with what other behavior?

• A. Sexual promiscuity
• B. Poor body image
• C. Dropping out of school
• D. Drug experimentation

Correct answer: B

Rationale: When addressing obesity in adolescents, it is crucial to consider that poor body image is a common behavior associated with obesity. As adolescents gain weight, they may experience a decrease in self-esteem and a negative perception of their body. This can contribute to a cycle of unhealthy behaviors and impact their overall well-being. The other choices are less commonly associated with obesity in adolescents. Sexual promiscuity may be influenced by various factors unrelated to obesity, dropping out of school is more often linked to academic challenges or social issues, and drug experimentation can stem from a range of influences but is not directly correlated with obesity.

3. A couple asks the nurse about risks of several birth control methods. What is the most appropriate response by the nurse?

• A. Norplant is safe and can be easily removed.
• B. Oral contraceptives should not be used by smokers.
• C. Depo-Provera is convenient with few side effects.
• D. The IUD provides protection against pregnancy and infection.

Correct answer: B

Rationale: The correct answer is that oral contraceptives should not be used by smokers. The use of oral contraceptives in a woman who smokes increases the risk of cardiovascular problems, such as thromboembolic disorders. This is due to the combined effect of smoking and hormonal contraceptives. Choices A, C, and D are incorrect because they do not address the specific risk associated with smoking and oral contraceptives. Norplant's safety and ease of removal, Depo-Provera's convenience with few side effects, and the IUD's protection against pregnancy and infection are important points but not directly related to the increased risks for smokers using oral contraceptives.

4. How does shock typically progress?

• A. Compensated to hypotensive shock in hours and hypotensive shock to cardiac arrest in minutes
• B. Compensated to hypotensive shock in minutes and hypotensive shock to cardiac arrest in hours
• C. Hypotensive to compensated shock in hours and compensated shock to cardiac arrest in minutes
• D. Hypotensive to compensated shock in minutes and compensated shock to cardiac arrest in hours

Correct answer: A

Rationale: Shock typically progresses from a compensated state to hypotensive shock over a period of hours. In the compensated phase, the body is trying to maintain perfusion. It is crucial to identify and intervene during this phase to prevent progression to hypotensive shock, where blood pressure drops significantly. If not promptly managed, hypotensive shock can rapidly deteriorate into cardiac arrest in minutes due to inadequate perfusion to vital organs. Choices B, C, and D are incorrect as they do not follow the typical progression of shock stages as seen in clinical practice. Understanding the stages of shock and their timeframes is crucial for early recognition and appropriate intervention to prevent further deterioration.

5. A child presents to the emergency department with colicky abdominal pain in the lower right quadrant. What disorder is suspected based on these symptoms?

• A. Peritonitis
• B. Appendicitis
• C. Intussusception
• D. Hirschsprung's disease

Correct answer: B

Rationale: The child's presentation of colicky abdominal pain in the lower right quadrant is classic for appendicitis. Appendicitis typically presents with localized pain that starts near the umbilicus and then shifts to the right lower quadrant. Peritonitis, on the other hand, is characterized by diffuse abdominal pain, tenderness, and guarding, usually resulting from organ perforation or intestinal obstruction. Intussusception is associated with acute, severe abdominal pain and currant jelly-like stools due to intestinal telescoping. Hirschsprung's disease, which lacks ganglion cells in the colon, manifests with symptoms like constipation, abdominal distension, and foul-smelling, ribbon-like stools.
