Nursing Elites

1. The term 'epidemiology' is best defined as the study of:

• A. The causes of disease
• B. The distribution and determinants of health-related states in populations
• C. The treatment and prevention of disease
• D. The healthcare system and its effectiveness

Correct answer: B

Rationale: Epidemiology is the study of the distribution and determinants of health-related states in populations. Choice A is incorrect because epidemiology focuses on more than just causes but also on distribution and determinants. Choice C is incorrect as it specifically relates to public health and not just treatment and prevention. Choice D is incorrect as epidemiology is broader than just focusing on the healthcare system and its effectiveness.

2. In addition to disturbances in mental awareness and orientation, a client with cognitive impairment is also likely to show loss of ability in

• A. Hearing, speech, and sight
• B. Endurance, strength, and mobility
• C. Learning, creativity, and judgment
• D. Balance, flexibility, and coordination

Correct answer: C

Rationale: Individuals with cognitive impairment often experience difficulties in learning new information, creative thinking, and making sound judgments. Loss of ability in hearing, speech, and sight (Choice A) is more closely related to sensory impairments rather than cognitive impairment. Endurance, strength, and mobility (Choice B) are more associated with physical capabilities rather than cognitive functions. Balance, flexibility, and coordination (Choice D) are related to motor skills and physical coordination, not cognitive impairment.

3. When a nurse teaches a community about the importance of hand hygiene, the nurse is engaging in:

• A. Primary prevention
• B. Secondary prevention
• C. Tertiary prevention
• D. Quaternary prevention

Correct answer: A

Rationale: The correct answer is A: Primary prevention. Primary prevention aims to prevent the occurrence of a disease or injury before it happens. Teaching about hand hygiene to the community helps in preventing infections from occurring in the first place. Choice B, Secondary prevention, involves early detection and treatment to halt or slow the progress of a condition. This would involve screening or early intervention after exposure. Choice C, Tertiary prevention, focuses on managing the disease to prevent complications, recurrence, or deterioration. This would include rehabilitation and monitoring to prevent further complications. Choice D, Quaternary prevention, relates to actions taken to avoid unnecessary interventions or over-medicalization. This usually involves questioning the necessity of certain medical procedures or treatments to prevent harm to patients.

4. James is an 18-month-old child who has had a cough for 7 days with no general danger signs, a temperature of 37.5°C, and a respiratory rate of 41 breaths per minute. How will you classify James' breathing?

• A. Slow breathing
• B. Fast breathing
• C. Normal breathing
• D. Very fast breathing

Correct answer: C

Rationale: The correct answer is 'Normal breathing.' A respiratory rate of 41 breaths per minute is considered normal for an 18-month-old child. Choices A, B, and D are incorrect because a respiratory rate of 41 breaths per minute falls within the normal range for a child of James' age and does not indicate slow, fast, or very fast breathing.

5. Postoperative orders for a client undergoing a mitral valve replacement include monitoring pulmonary artery pressure together with pulmonary capillary wedge pressure with a pulmonary artery catheter. This action by the nurse will assess

• A. Right ventricular pressure
• B. Left ventricular end-diastolic pressure
• C. Acid-Base balance
• D. Coronary artery stability

Correct answer: B

Rationale: The correct answer is B: Left ventricular end-diastolic pressure. Pulmonary capillary wedge pressure is used to assess left ventricular end-diastolic pressure. This measurement provides valuable information on the filling pressure of the left ventricle. Choices A, C, and D are incorrect because monitoring pulmonary capillary wedge pressure does not directly assess right ventricular pressure, acid-base balance, or coronary artery stability.
