1. Almost all (99%) of the calcium in the body is used for?
- A. regulating the transmission of nerve impulses
- B. providing energy for cells
- C. providing rigidity for the bones
- D. regulating muscle contraction
Correct answer: C
Rationale: The correct answer is C: providing rigidity for the bones. Almost all of the calcium in the body is utilized for maintaining the strength and structure of bones and teeth. Calcium plays a crucial role in skeletal health by providing rigidity and support to the skeletal system. Choices A, B, and D are incorrect because while calcium is essential for various physiological functions like nerve transmission, cell energy production, and muscle contraction, the majority of calcium in the body is primarily allocated for bone health.
2. A client with obsessive-compulsive disorder (OCD) is being cared for by a nurse. Which intervention should the nurse implement to help the client manage compulsive behaviors?
- A. Encourage the client to suppress compulsive behaviors.
- B. Allow the client to perform compulsive behaviors with limits.
- C. Teach the client relaxation techniques to manage anxiety.
- D. Discourage the client from performing compulsive behaviors.
Correct answer: B
Rationale: Allowing the client to perform compulsive behaviors with limits is a therapeutic intervention for managing OCD. This approach grants the client some autonomy while ensuring that the behaviors do not excessively disrupt daily life. Setting boundaries helps structure the behaviors, decreasing anxiety and distress associated with OCD. Encouraging the client to suppress compulsive behaviors (choice A) may lead to increased anxiety and potential worsening of symptoms. Teaching relaxation techniques (choice C) is beneficial for managing anxiety in general but may not directly address the compulsive behaviors. Discouraging the client from performing compulsive behaviors (choice D) without providing alternative strategies or support may increase distress and resistance.
3. A tension pneumothorax requires a needle thoracostomy and/or chest tube placement as treatment to which component of the pathophysiology of the condition?
- A. An accumulation of blood in the pleural space, which makes it difficult for the lungs to exchange gases.
- B. Extreme pain caused by a fractured rib
- C. A large accumulation of trapped air in the pleural space affecting both the lungs and heart.
- D. Sudden failure of the respiratory system due to fluid accumulation in the alveoli
Correct answer: C
Rationale: A tension pneumothorax is characterized by a large accumulation of trapped air in the pleural space, creating pressure that affects both the lungs and heart. This condition can lead to life-threatening consequences by shifting mediastinal structures and impairing cardiac function. Treatment involves decompressing the trapped air to relieve the tension. Choices A, B, and D are incorrect as they do not describe the primary pathophysiological mechanism of tension pneumothorax, which is the accumulation of air in the pleural space, not blood, rib fractures, or alveolar fluid accumulation.
4. A client with generalized anxiety disorder (GAD) is being discharged. Which of the following instructions should the nurse include in the discharge teaching? Select one that does not apply.
- A. Practice relaxation techniques daily
- B. Avoid caffeine and alcohol
- C. Engage in regular physical activity
- D. Use benzodiazepines as the first line of treatment
Correct answer: D
Rationale: When discharging a client with GAD, it is important to provide instructions that promote holistic well-being and support without exacerbating the condition. Practicing relaxation techniques daily, avoiding caffeine and alcohol, and engaging in regular physical activity can help manage anxiety symptoms effectively. These strategies focus on self-care and healthy lifestyle choices. Seeking support from friends and family also plays a crucial role in maintaining mental health. However, using benzodiazepines as the first line of treatment is not recommended due to their potential for dependence and other associated risks. Non-pharmacological interventions and therapy are usually preferred as initial approaches in managing GAD. Therefore, the option 'D: Use benzodiazepines as the first line of treatment' is incorrect and should not be included in the discharge teaching for a client with GAD.
5. A nurse is assessing the nutritional status of an infant who is 6 months old. The infant weighed 2.7 kg at birth. Which of the following indicate to the nurse that the infant is within expected range?
- A. 5.5 kg
- B. 6.4 kg
- C. 4.5 kg
- D. 3.6 kg
Correct answer: B
Rationale: An infant's weight should approximately double by 6 months. A weight of 6.4 kg indicates normal growth from a birth weight of 2.7 kg.
