1. What drives respiration in a patient with advanced chronic respiratory failure?

• A. Hypoxemia
• B. Hypocapnia
• C. Hypercapnia
• D. None of the above

Correct answer: A

Rationale: In patients with advanced chronic respiratory failure, such as those with chronic obstructive pulmonary disease (COPD), the respiratory drive shifts from being primarily stimulated by high levels of carbon dioxide (hypercapnia) to being driven by low oxygen levels (hypoxemia). This shift is due to the body's adaptation to chronic respiratory acidosis and hypoxemia. As a result, hypoxemia becomes the primary stimulus for respiration in these patients. Hypocapnia, a low level of carbon dioxide, is not a common driver of respiration in patients with advanced chronic respiratory failure. Therefore, the correct answer is hypoxemia.

2. A patient has come into the emergency room after an injury at work in which their upper body was pinned between two pieces of equipment. The nurse notes bruising in the upper abdomen and chest. The patient is complaining of sharp chest pain, having difficulty breathing, and their trachea is deviated to the left side. Which of the following conditions are these symptoms most closely associated with?

• A. Left-sided pneumothorax
• B. Pleural effusion
• C. Atelectasis
• D. Right-sided pneumothorax

Correct answer: D

Rationale: The patient is most likely suffering from a right-sided pneumothorax. Symptoms of a pneumothorax include sharp chest pain, difficulties with breathing, decreased vocal fremitus, absent breath sounds, and tracheal shift to the opposite of the affected side. In this case, the patient's trachea is deviated to the left side, indicating a right-sided pneumothorax. Choices A, B, and C can be eliminated as they do not present with the specific symptoms described in the scenario. Left-sided pneumothorax would not cause tracheal deviation to the left side. Pleural effusion typically presents with dull chest pain and decreased breath sounds, not sharp chest pain and tracheal deviation. Atelectasis would not cause tracheal deviation and is more associated with lung collapse rather than air accumulation in the pleural space.

3. During your evaluation of a 14-year-old girl with a BMI of 18, she reports inability to eat, induced vomiting, and severe constipation. Which of the following would you most likely suspect?

• A. Multiple sclerosis
• B. Anorexia nervosa
• C. Bulimia nervosa
• D. Systemic sclerosis

Correct answer: B

Rationale: The clinical presentation described in the question is highly suggestive of anorexia nervosa. Anorexia nervosa is characterized by self-imposed starvation due to a distorted body image and an intense fear of gaining weight, even when the individual is underweight. The patient's symptoms of inability to eat, induced vomiting, and severe constipation align with the behavior seen in anorexia nervosa, including restrictive eating patterns and purging behaviors. Multiple sclerosis (Choice A) is a neurological disorder, not associated with the described symptoms. Bulimia nervosa (Choice C) typically involves binge eating followed by purging behaviors, which is different from the described primary restriction seen in anorexia nervosa. Systemic sclerosis (Choice D) is a connective tissue disorder and is not related to the symptoms of self-induced vomiting and severe constipation reported in this case.

4. The healthcare provider calculates the IV flow rate for a patient receiving lactated Ringer's solution. The patient needs to receive 2000mL of Lactated Ringer's over 36 hours. The IV infusion set has a drop factor of 15 drops per milliliter. How many drops per minute should the healthcare provider set the IV to deliver?

• A. 8
• B. 10
• C. 14
• D. 18

Correct answer: C

Rationale: To determine the drops per minute, we use the formula Drops Per Minute = (Milliliters x Drop Factor) / Time in Minutes. In this case, Drops Per Minute = (2000mL x 15 drops/mL) / (36 hours x 60 minutes/hour) = 30000 / 2160 = 13.89 (approximately 14). Therefore, the correct answer is 14 drops per minute. Choice A (8), Choice B (10), and Choice D (18) are incorrect as they do not correctly calculate the drops per minute based on the given information.

5. The nurse is reviewing the characteristics of culture. Which statement is correct regarding the development of one's culture?

• A. Learned through language acquisition and socialization.
• B. Genetically determined on the basis of racial background.
• C. A nonspecific phenomenon and is adaptive but unnecessary.
• D. Biologically determined on the basis of physical characteristics.

Correct answer: A

Rationale: Culture is a complex phenomenon that includes attitudes, beliefs, self-definitions, norms, roles, and values learned from birth through the processes of language acquisition and socialization. It is not biologically or genetically determined, but rather acquired through social interactions. The correct answer, 'Learned through language acquisition and socialization,' aligns with the understanding that culture is a learned behavior. Choices B, C, and D are incorrect because culture is not genetically determined, nonspecific, or biologically based on physical characteristics. Understanding that culture is acquired through language and socialization is essential for healthcare providers to provide culturally competent care.
