A client is told that his test is positive, but in fact, the client does not have the disease tested for. Which type of false report is this an example of?
- A. positive
- B. false positive
- C. negative
- D. false negative
Correct Answer: B
Rationale: The correct answer is 'false positive.' A false-positive result occurs when a test result is labeled positive in error, when the actual result is negative. In this scenario, the client received a positive test result incorrectly, as he does not have the disease being tested for. Choice A ('positive') is too vague and does not specify that the result was incorrect. Choice C ('negative') is the opposite of what happened in the scenario. Choice D ('false negative') refers to a situation where a test result is labeled negative incorrectly, which is not the case in this scenario.

Upon first meeting, a new nurse manager makes eye contact, smiles, initiates conversation about the previous work experience of nurses, and encourages active participation by nurses in the dialogue. Her behavior is an example of:
- A. Aggressiveness.
- B. Passive aggressiveness.
- C. Passiveness.
- D. Assertiveness.
Correct Answer: D
Rationale: The correct answer is 'Assertiveness.' This nurse manager is demonstrating assertive behavior by confidently engaging with the nurses, showing interest in their work experience, and encouraging active participation. Aggressive behavior is forceful and dominating, while passive behavior is submissive and timid. Passive-aggressive behavior involves indirect manipulation or control, which is not demonstrated in this scenario.
What is the most common cause of injury from a house fire?
- A. Explosion
- B. Falls from second-story windows
- C. Thermal damage to skin and body surfaces
- D. Inhalation injury
Correct Answer: D
Rationale: Inhalation injury is the most common cause of injury from a house fire. When a fire occurs, the smoke produced contains harmful gases and particles that can be inhaled, leading to serious respiratory issues. This makes inhalation injury the primary concern during a house fire. Choices A, B, and C are less likely to be the primary cause of injury. While explosions may occur in some cases, inhalation of smoke and toxic fumes is generally the most prevalent danger. Falls from windows and thermal damage to the skin are also significant risks but typically occur after inhalation injuries in the sequence of events during a house fire.
How does cancer affect pain tolerance in elderly clients?
- A. Remain constant.
- B. Decrease.
- C. Increase.
- D. Cancer has no impact on pain tolerance in elderly clients.
Correct Answer: B
Rationale: Pain tolerance in elderly clients with cancer is likely to decrease due to factors such as diminished adaptative capacity, increased physical discomfort, and the psychological impact of the disease. Cancer is known to cause various physical and emotional stressors that can lower the pain threshold, leading to a decrease in pain tolerance. Choices A, C, and D are incorrect because cancer and its associated effects typically result in a decrease in pain tolerance rather than remaining constant, increasing, or having no impact.
In which of the following conditions might increased cortisol levels be found?
- A. Cushing's syndrome
- B. Addison's disease
- C. Renal failure
- D. Congestive heart failure
Correct Answer: A
Rationale: Cushing's syndrome is characterized by increased cortisol levels due to the overproduction of cortisol by the adrenal glands. This excess cortisol can lead to various symptoms and complications. Addison's disease is associated with decreased cortisol levels as it results from adrenal insufficiency, making it an incorrect choice in this context. Renal failure and congestive heart failure are not typically linked to abnormal cortisol levels, further indicating that they are not the conditions where increased cortisol levels are found.
Following a classic cholecystectomy resection for multiple stones, the PACU nurse observes serosanguinous drainage on the dressing. The most appropriate intervention is to:
- A. notify the physician of the drainage.
- B. change the dressing.
- C. reinforce the dressing.
- D. apply an abdominal binder
Correct Answer: C
Rationale: Serosanguinous drainage is expected after a classic cholecystectomy resection. The appropriate intervention is to reinforce the dressing to maintain pressure and promote clot formation. Changing the dressing prematurely increases the risk of infection as it disturbs the wound. Applying an abdominal binder is not indicated as it can interfere with visualizing the dressing and assessing for any signs of bleeding or infection. Notifying the physician is not necessary at this point unless there are signs of excessive bleeding or other concerning symptoms.
