Nursing Elites

1. A nurse reviewed the arterial blood gas reading of a 25-year-old male. The nurse should be able to conclude the patient is experiencing which of the following conditions?

• A. metabolic acidosis
• B. respiratory acidosis
• C. metabolic alkalosis
• D. respiratory alkalosis

Correct answer: respiratory alkalosis

Rationale: The correct answer is respiratory alkalosis. In respiratory alkalosis, there is an elevated pH and low carbon dioxide levels (PaCO2 < 35 mmHg). In the given arterial blood gas reading, the patient's pH is 7.41 (within normal range), PaCO2 is 29 mmHg (below normal range), indicating respiratory alkalosis. The bicarbonate level is normal (25 mEq/l), ruling out metabolic acidosis or alkalosis. The low PaO2 (54 mmHg) may indicate hypoxemia, but it is not directly related to the acid-base disorder being assessed. Metabolic acidosis (choice A) is characterized by low pH and low bicarbonate levels, which are not present in this case. Respiratory acidosis (choice B) is indicated by low pH and high PaCO2 levels, which also do not match the provided data. Metabolic alkalosis (choice C) is defined by high pH and high bicarbonate levels, which are not seen in this scenario.

2. A client is having psychological counseling for problems communicating with his mother. Which model of stress is the most useful in reference to this stressor?

• A. Adaptation Model
• B. Stimulus-Based Model
• C. Transaction-Based Model
• D. Selye’s Model of Stress

Correct answer: Transaction-Based Model

Rationale: The Transaction-Based Model, proposed by R.S. Lazarus, is the most relevant model of stress in the context of a client facing communication issues with his mother. This model takes into consideration individual differences and cognitive processes that occur between a stressor and the individual's response. It emphasizes the importance of how the individual perceives and interprets the stressor, incorporating mental and psychological components. In this scenario, the client's difficulties in communicating with his mother involve complex cognitive processes and individual perceptions, making the Transaction-Based Model the most suitable choice. The other options are not as relevant in this context: the Adaptation Model focuses on adjustment to stress over time, the Stimulus-Based Model emphasizes external factors as stressors, and Selye’s Model of Stress mainly centers on the physiological response to stress.

3. When treating anemia in clients with renal failure, erythropoietin should be given in conjunction with:

• A. iron, folic acid, and B12.
• B. an increase in protein in the diet.
• C. vitamins A and C.
• D. an increase in calcium in the diet.

Correct answer: iron, folic acid, and B12.

Rationale: Erythropoietin is used to stimulate red blood cell production in clients with renal failure. To effectively increase red blood cell production, adequate levels of iron, folic acid, and B12 are necessary. These nutrients play crucial roles in erythropoiesis. Choices B, an increase in protein in the diet, is not directly related to enhanced erythropoiesis and can potentially worsen uremia. Choices C and D, vitamins A and C, and an increase in calcium in the diet, are not directly involved in red blood cell production and are not essential in this context.

4. A nurse working in a pediatric clinic observes the following situations. Which of the following may indicate a delayed child to the nurse?

• A. A 12-month-old that does not 'cruise'.
• B. An 8-month-old that can sit upright unsupported.
• C. A 6-month-old that is rolling prone to supine.
• D. A 3-month-old that does not roll supine to prone.

Correct answer: A 12-month-old that does not 'cruise'.

Rationale: The correct answer is 'A 12-month-old that does not 'cruise''. At 12 months, a child should at least be 'cruising' (holding on to objects to walk), which is considered pre-walking. The other choices describe age-appropriate developmental milestones: sitting upright unsupported by 8 months, rolling prone to supine by 6 months, and rolling supine to prone by 3 months. Not 'cruising' at 12 months may indicate a delay in motor skills development.

5. Nurses should understand the chain of infection because it refers to:

• A. the linkages involved in disease transmission.
• B. the sequence required for transmission of disease.
• C. the clustering of bacteria in a specific pattern.
• D. increasing virulence patterns among microorganisms.

Correct answer: the sequence required for transmission of disease.

Rationale: The chain of infection refers to the sequence required for the transmission of disease, involving steps like the pathogen's presence, movement from a reservoir, and entry into a susceptible host. Understanding this sequence helps healthcare professionals, including nurses, in implementing effective infection control measures. Choices A, C, and D are incorrect because they do not accurately describe the concept of the chain of infection. Choice A is too broad and does not specifically address the sequential nature of disease transmission. Choice C focuses on bacterial clustering rather than the transmission process. Choice D mentions virulence patterns, which are not the primary focus of the chain of infection concept.
