1. What characterizes Obsessive Compulsive Disorder?
- A. Uncontrollable impulse to perform an act or ritual repeatedly
- B. Persistent thoughts and behavior
- C. Recurring unwanted and disturbing thoughts
- D. Pathological persistence of unwilled thoughts
Correct answer: A
Rationale: Obsessive Compulsive Disorder (OCD) is characterized by the uncontrollable impulse to perform an act or ritual repeatedly (Choice A). This is driven by recurring unwanted and disturbing thoughts (Choice C), but the distinguishing factor is the compulsive behavior, making choice A the most accurate. While choice B can be seen as true, it lacks the specific detail of the compulsive behavior that makes A a better answer. Choice D is not incorrect, but it uses terminology that is less precise and less commonly used to describe OCD, making it a less accurate choice than A. The provided rationale is not relevant to the question.
2. What procedure is most appropriate for the assessment of an abdominal circumference related to a bowel obstruction?
- A. Measuring the abdomen after feedings
- B. Marking the point of measurement with a pen
- C. Measuring the circumference at the symphysis pubis
- D. Using a new tape measure with each assessment to ensure accuracy
Correct answer: B
Rationale: Marking the point of measurement ensures consistent and accurate assessments of abdominal circumference, especially important in conditions like bowel obstruction where changes need to be monitored closely.
3. When providing discharge teaching to a client prescribed home oxygen therapy, what information should the nurse include?
- A. Increase the oxygen flow rate during activity
- B. Avoid smoking and open flames near oxygen
- C. Store the oxygen tank in a warm, dry place
- D. Turn off the oxygen when not in use
Correct answer: B
Rationale: The correct answer is B: 'Avoid smoking and open flames near oxygen.' This information is crucial to prevent fire hazards when using home oxygen therapy. Smoking and open flames near oxygen can lead to serious accidents. Choice A is incorrect because increasing the oxygen flow rate during activity without healthcare provider guidance can be dangerous. Choice C is incorrect as oxygen tanks should be stored in a well-ventilated area, not necessarily warm and dry. Choice D is incorrect as oxygen should not be turned off and on by the client, as it can affect the therapy's effectiveness and cause safety issues.
4. Innate resistance or immunity:
- A. Involves 'memory'
- B. Is a development of an individual's later years
- C. Is a relatively slow and specific process
- D. Depends on physical, mechanical, and biochemical barriers
Correct answer: D
Rationale: Innate resistance or immunity relies on the body's natural defenses like physical, mechanical, and biochemical barriers. These barriers act as the first line of defense against pathogens and do not involve memory (choice A). Innate immunity is present from birth and does not develop over an individual's later years (choice B). Additionally, innate immunity is a rapid and nonspecific process, not a slow and specific one (choice C). Therefore, the correct answer is D.
5. A client at risk for iron-deficiency anemia is being taught by a nurse about optimizing dietary intake of iron. The nurse should explain that which of the following sources of iron is easiest for the body to absorb?
- A. Spinach
- B. Cantaloupe
- C. Chicken
- D. Lentils
Correct answer: C: Chicken
Rationale: The correct answer is 'Chicken.' Chicken contains heme iron, which is more easily absorbed by the body compared to non-heme iron found in plant-based sources like spinach, cantaloupe, and lentils. Heme iron, as present in chicken, is more bioavailable and is better absorbed by the body, making it an excellent source of iron for individuals at risk of iron-deficiency anemia. Spinach, cantaloupe, and lentils contain non-heme iron, which is not as efficiently absorbed as heme iron.
