1. What are Korotkoff sounds?

A. Sounds noted during diastole.
B. The result of the vibration of blood against artery walls while blood pressure readings are being taken.
C. Sounds only noted by skilled cardiologists.
D. Distinct sounds which are classified into 6 phases.

Correct answer: B

Rationale: Korotkoff sounds are the sounds that occur when blood flows in an artery that has been temporarily compressed during a blood pressure measurement. These sounds result from the vibration of blood against the artery walls as the pressure cuff is released. There are five distinct phases of Korotkoff sounds, which healthcare providers are trained to identify during blood pressure assessment. The correct answer, choice B, accurately describes the nature of Korotkoff sounds and how they are generated. Choices A, C, and D are incorrect because Korotkoff sounds are not specific to diastole, not limited to skilled cardiologists, and categorized into five phases, not six.

2. Nursing care plans are _______________?

A. written by CNAs before they provide care
B. guidelines of care that all nursing team members use
C. used by nurses but not by nursing assistants
D. used by nursing assistants but not by nurses

Correct answer: B

Rationale: Nursing care plans are comprehensive documents created by registered nurses to outline individualized care for patients. These plans serve as guidelines for all members of the nursing team, including nursing assistants, to ensure consistent and quality care. Choice A is incorrect as CNAs typically assist in implementing the care plan rather than creating it. Choice C is incorrect as nursing care plans are utilized by all members of the nursing team, not exclusive to only nurses. Choice D is incorrect as nursing assistants also utilize nursing care plans to provide patient care effectively.

3. According to the American Heart Association standards, high-quality CPR for an adult includes all of the following EXCEPT:

A. Push hard
B. Push fast
C. Allow chest recoil between compressions
D. Pause CPR as each drug is administered

Correct answer: D

Rationale: High-quality CPR for adults should not be paused for drug administration. The correct CPR technique involves pushing hard and fast, at a rate of at least 100 compressions per minute and to a depth of at least 2 inches. It is also essential to allow chest recoil between compressions to enable proper blood circulation. Pausing CPR for drug administration would delay the delivery of continuous chest compressions, which are crucial for maintaining blood flow and oxygenation during cardiac arrest.

4. The nurse is discussing the term subculture with a student nurse. Which statement by the nurse would best describe subculture?

A. "Fitting as many people as possible into the majority culture."?
B. "Identifying small groups of people who do not want to be identified with the larger culture."?
C. "Singling out groups of people who suffer differential and unequal treatment as a result of cultural variations."?
D. "Recognizing groups of people within a culture with shared characteristics that are not common to all members of the culture."?

Correct answer: D

Rationale: A subculture refers to a group of people within a larger culture who share distinct beliefs, values, or attitudes that are not universal among all members of the larger culture. Subcultures can emerge based on factors such as ethnicity, religion, education, occupation, age, and gender. The correct answer describes the concept of a subculture accurately. Choices A, B, and C are incorrect because they do not capture the essence of a subculture. Fitting people into the majority culture, identifying small groups who distance themselves from the larger culture, or singling out individuals facing differential treatment do not define subculture. Subcultures represent specific groups with shared characteristics that differentiate them from the broader cultural norms.

5. Your patient ate an 8-ounce cup of Italian ice. How much will you record on the patient's Intake and Output form in terms of this patient's fluid intake?

A. 240 cc
B. 120 cc
C. 8 cc
D. 0 cc because Italian ice is not a fluid

Correct answer: A

Rationale: The correct answer is 240 cc. Italian ice is considered a fluid, so you would record the intake of 240 cc. Choice B (120 cc) and Choice C (8 cc) are incorrect as they do not reflect the correct amount of fluid intake from an 8-ounce cup of Italian ice. Choice D (0 cc) is incorrect because Italian ice does count as a fluid intake and should be recorded as such.
