1. Which pathology is associated with an asthma condition?
- A. Chronic dilation and inflammation of the bronchi.
- B. Recurrent spasms of the airways accompanied by edema and mucus production.
- C. Progressive loss of lung function due to destruction of alveolar walls.
- D. Infection of the lung parenchyma.
Correct answer: B
Rationale: The correct answer is B: Recurrent spasms of the airways accompanied by edema and mucus production. Asthma is characterized by bronchospasms, inflammation, swelling of the airways, and increased mucus production. This leads to airway constriction, making it difficult to breathe. Choices A, C, and D do not represent the typical pathology seen in asthma. Chronic dilation and inflammation of the bronchi (Choice A) is more characteristic of bronchiectasis, progressive loss of lung function due to destruction of alveolar walls (Choice C) is seen in conditions like emphysema, and infection of the lung parenchyma (Choice D) is more related to conditions like pneumonia.
2. The parents of a child suffering from depression ask the nurse what causes depression in children. Which answer is an appropriate response by the nurse?
- A. The causes of major depression are unknown.
- B. Major affective disorders in parents increase depression in children.
- C. Boys are more likely than girls to be depressed.
- D. The prevalence rate is higher in prepubescent children.
Correct answer: B
Rationale: The correct answer is B because while the exact causes of depression in children are not fully understood, research indicates that children are more likely to experience depression if their parents have a major affective disorder. Choice A is incorrect because it suggests that the causes of major depression are entirely unknown, which is not accurate. Choice C is incorrect as there is no conclusive evidence that boys are more likely than girls to be depressed. Choice D is incorrect as the prevalence rate of depression is not necessarily higher in prepubescent children specifically.
3. In planning nursing care for a bedfast client, which factor is most likely to contribute to the development of deep vein thrombosis (DVT) in an immobile client?
- A. Atherosclerotic plaque formation.
- B. Stasis of blood flow.
- C. Endothelial damage.
- D. Atherosclerotic vessel changes.
Correct answer: B
Rationale: The correct answer is B: Stasis of blood flow. Stasis of blood flow in immobile clients increases the risk of DVT, as lack of movement can cause blood to pool and clot. Atherosclerotic plaque formation (choice A) and atherosclerotic vessel changes (choice D) are more related to arterial diseases rather than DVT. Endothelial damage (choice C) can contribute to the development of DVT, but in an immobile client, stasis of blood flow is the most significant factor.
4. The settings on a client's synchronized intermittent mandatory ventilation (SIMV) are respiratory rate 12 breaths/minute, tidal volume at 600 mL, FiO2 35%, and positive end-expiratory pressure (PEEP) 5 cm H2O. Which assessment finding necessitates immediate intervention by the nurse?
- A. Bilateral crackles in the lung bases.
- B. Low-pressure indicator alarm.
- C. Oxygen saturation of 91%.
- D. Respiratory rate of 18 breaths/minute.
Correct answer: B
Rationale: A low-pressure alarm may indicate a disconnection or leak in the system, which needs immediate intervention. Bilateral crackles in the lung bases may indicate fluid overload but do not require immediate intervention in this case. An oxygen saturation of 91% is concerning but not as urgent as a potential equipment issue. A respiratory rate of 18 breaths/minute is higher than the set rate but may not necessitate immediate intervention unless accompanied by other distress symptoms.
5. A client with peptic ulcer disease is prescribed sucralfate. What is the mechanism of action of this medication?
- A. Neutralizes stomach acid
- B. Decreases gastric acid secretion
- C. Covers the ulcer site and protects it from acid
- D. Improves gastric motility
Correct answer: C
Rationale: The correct answer is C: Covers the ulcer site and protects it from acid. Sucralfate works by forming a protective barrier over ulcers, shielding them from stomach acid and promoting healing. Choice A, neutralizing stomach acid, is incorrect as sucralfate does not neutralize acid but acts as a physical barrier. Choice B, decreasing gastric acid secretion, is not the mechanism of action of sucralfate. Choice D, improving gastric motility, is unrelated to sucralfate's action on peptic ulcers.
