1. Which of the following best describes the purpose of a root cause analysis (RCA)?

A. Identify the person responsible for an error
B. Determine who should be disciplined
C. Discover the underlying causes of an error
D. Evaluate the effectiveness of a new policy

Correct answer: C

Rationale: The correct answer is C: 'Discover the underlying causes of an error.' Root cause analysis (RCA) focuses on identifying the fundamental reason(s) that led to an error or problem rather than placing blame on individuals. Choice A and B are incorrect as RCA is not about pinpointing a specific person to blame or determining disciplinary actions. Choice D is also incorrect as the primary goal of RCA is not to evaluate policy effectiveness but to uncover the root causes of issues for effective problem-solving.

2. Which of the following is an example of a sentinel event in healthcare?

A. A patient falling in the hospital without injury
B. A near-miss medication error
C. An unexpected patient death unrelated to the natural course of illness
D. A patient developing an infection during a hospital stay

Correct answer: C

Rationale: The correct answer is C. A sentinel event in healthcare is an unexpected patient death unrelated to the natural course of illness. These events are serious occurrences that warrant immediate investigation and response to prevent their recurrence and ensure patient safety. Choices A, B, and D do not fit the definition of a sentinel event. While choices A, B, and D are serious incidents, they do not involve an unexpected patient death unrelated to the natural course of illness, which is the defining characteristic of a sentinel event.

3. A 27-year-old patient admitted with diabetic ketoacidosis (DKA) has a serum glucose level of 732 mg/dL and serum potassium level of 3.1 mEq/L. Which action prescribed by the healthcare provider should the nurse take first?

A. Place the patient on a cardiac monitor
B. Administer IV potassium supplements
C. Obtain urine glucose and ketone levels
D. Start an insulin infusion at 0.1 units/kg/hr

Correct answer: A

Rationale: In a patient with diabetic ketoacidosis (DKA), the initial priority is to assess for any cardiac arrhythmias due to electrolyte imbalances. Since the patient has a low serum potassium level of 3.1 mEq/L, placing the patient on a cardiac monitor is crucial to monitor for any potential cardiac complications. Administering IV potassium supplements (Choice B) may be needed, but it is not the first action to take. Obtaining urine glucose and ketone levels (Choice C) and starting an insulin infusion (Choice D) are important interventions in managing DKA, but ensuring patient safety by monitoring for arrhythmias takes precedence.

4. A 38-year-old patient who has type 1 diabetes plans to swim laps daily at 1:00 PM. The clinic nurse will plan to teach the patient to

A. check glucose levels before, during, and after swimming.
B. delay eating the noon meal until after swimming.
C. increase the morning dose of neutral protamine Hagedorn (NPH) insulin.
D. time the morning insulin injection so that the peak occurs while swimming.

Correct answer: A

Rationale: The correct answer is to teach the patient to check glucose levels before, during, and after swimming. This is important to monitor blood sugar levels and make adjustments as needed to prevent hypoglycemia or hyperglycemia. Delaying eating the noon meal until after swimming (Choice B) is not advisable as the patient needs proper nutrition both before and after exercise. Increasing the morning dose of NPH insulin (Choice C) should not be done without proper medical advice as it can lead to hypoglycemia. Timing the morning insulin injection to coincide with swimming (Choice D) is risky as the peak effect of insulin may lead to hypoglycemia during swimming.

5. Which level in Maslow's hierarchy is rarely met?

A. Esteem
B. Safety
C. Self-actualization
D. Belongingness

Correct answer: C

Rationale: The correct answer is C, 'Self-actualization.' Self-actualization, the highest level in Maslow's hierarchy, involves developing one's full potential and achieving personal growth. It is considered rarely met because it requires a deep understanding of oneself, a strong sense of purpose, and the ability to pursue intrinsic goals. Esteem (choice A) focuses on respect, recognition, and self-esteem, which are more commonly achieved than self-actualization. Safety (choice B) and belongingness (choice D) are also more commonly attained as they relate to basic needs for security and social connections, which are essential for overall well-being.
