1. Are kidneys part of the lymphatic system?
- A. True
- B. False
- C. Not Sure
- D. None of the above
Correct answer: False
Rationale: The correct answer is False. Kidneys are not part of the lymphatic system; they are part of the urinary system. The lymphatic system is a network of tissues and organs that help rid the body of toxins, waste, and other unwanted materials. Therefore, choices A, C, and D are incorrect because kidneys are not associated with the lymphatic system.
2. What fluid is found in spaces between the cells?
- A. Intracellular fluid
- B. Interstitial fluid
- C. Plasma
- D. Electrolyte
Correct answer: B
Rationale: The correct answer is B, Interstitial fluid. Interstitial fluid is the fluid that surrounds and occupies the spaces between cells, providing them with nutrients and removing waste. Choices A, C, and D are incorrect because intracellular fluid refers to fluid inside cells, plasma refers to the liquid component of blood, and electrolyte refers to substances that dissociate into ions in solution, affecting fluid balance but not specifically found in spaces between cells.
3. 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.
4. A nurse is teaching a client who has a new prescription for Spironolactone. Which of the following adverse effects should the nurse instruct the client to monitor?
- A. Hyperkalemia
- B. Hypoglycemia
- C. Hypocalcemia
- D. Hyponatremia
Correct answer: A
Rationale: Spironolactone is a potassium-sparing diuretic, so the nurse should monitor the client for hyperkalemia, which can cause muscle weakness and cardiac dysrhythmias.
5. While caring for a client who was injured in a motor-vehicle crash and reports dyspnea and severe pain, a nurse in the emergency department notes that the client's chest moves inward during inspiration and bulges out during expiration. The nurse should identify this finding as which of the following?
- A. Atelectasis
- B. Flail chest
- C. Hemothorax
- D. Pneumothorax
Correct answer: Flail chest
Rationale: Flail chest is characterized by paradoxical chest movement, where the chest moves inward during inspiration and bulges out during expiration. This occurs due to multiple rib fractures causing a segment of the chest wall to move independently from the rest of the thorax. Atelectasis refers to collapsed lung tissue, hemothorax is blood in the pleural space, and pneumothorax is air in the pleural space. In this scenario, the client's presentation aligns with the characteristic findings of flail chest.
