The mitral valve is synonymous with the term:
- A. Left ventricle
- B. Right atrium
- C. Bicuspid valve
- D. Tricuspid valve
Correct Answer: C
Rationale: The mitral valve, also known as the bicuspid valve, is located between the left atrium and the left ventricle, regulating blood flow from the left atrium into the left ventricle. The term 'bicuspid' refers to the valve's two cusps or leaflets. This distinguishes it from the tricuspid valve (Choice D), which has three cusps, making Choice D incorrect. The left ventricle (Choice A) and right atrium (Choice B) are not synonymous with the mitral valve. Therefore, the correct answer is C: Bicuspid valve.

Which of the following is one of the three smallest bones in the body?
- A. Vomer
- B. Distal phalanx of the small toe
- C. Stapes
- D. Coccyx
Correct Answer: C
Rationale: The stapes, along with the malleus and incus, are the three smallest bones in the human body. These bones are located in the inner ear and play a crucial role in hearing. The vomer is a bone in the nasal cavity and is not one of the smallest bones. The distal phalanx of the small toe is relatively larger and not among the smallest bones. The coccyx, also known as the tailbone, is not one of the smallest bones in the body.
While explaining an illness to a 10-year-old, what should the nurse keep in mind about the cognitive development at this age?
- A. They are able to make simple associations of ideas
- B. They are able to think logically in organizing facts
- C. Interpretation of events originates from their own perspective
- D. Conclusions are based on previous experiences
Correct Answer: B
Rationale: At the age of 10, children are in the concrete operations stage according to Piaget. They are capable of mature thought when allowed to manipulate and organize objects. This means they can think logically, organize facts, and understand cause-and-effect relationships. Choices A, C, and D are incorrect. While simple associations of ideas may occur, the key cognitive ability at this stage is the capacity for logical thought and organization of information. Interpretation of events from their own perspective is more characteristic of younger children, and conclusions based on previous experiences are more aligned with older children or adults.
Mr. Thomas is a well-groomed 68-year-old male patient who had prostate surgery two days ago. He has an indwelling catheter and a urinary drainage bag. You have weighed him at 9 am each morning for 3 mornings in a row. Today, on the 4th day, his morning weight is 3 pounds more than it was the day before. Why could he have gained these 3 pounds in one day, on a 1000 calorie diet?
- A. It is obvious that his visitors have been sneaking him junk food from the local fast-food restaurant.
- B. It may be that his urinary drainage bag was not emptied today and it was emptied on previous days.
- C. It is obvious that the scale is broken and it should be replaced immediately to prevent these false weights.
- D. A 3-pound weight gain is not significant enough to question and should just be noted.
Correct Answer: B
Rationale: The correct answer is that the weight gain may be due to the urinary drainage bag not being emptied today, while it was emptied on previous days. This scenario is common and can lead to an increase in weight that is not related to food intake. Choice A is incorrect because assuming visitors are sneaking junk food is speculative and not based on facts. Choice C is incorrect as there is no evidence to suggest the scale is broken. Choice D is incorrect because any unexplained weight gain should be investigated further, even if it seems insignificant at first.
A patient's body temperature has varied over the last 24 hours from 97.6 degrees F in the morning to 99 degrees F in the evening. The patient is worried that this change in temperature may indicate the beginning of a fever. Which of the following BEST explains this phenomenon?
- A. The patient definitely has a fever in the evening and should be seen by a doctor.
- B. The patient is experiencing changes related to a diurnal rhythm.
- C. The patient is more than likely taking their temperature incorrectly.
- D. The patient is experiencing changes related to fluctuating daily hormones.
Correct Answer: B
Rationale: The patient is experiencing changes related to a diurnal rhythm. Diurnal rhythm is the phenomenon of body temperature fluctuating depending on the time of day. Temperatures taken in the morning are typically lower than those taken throughout the rest of the day. Choice A is incorrect because a single elevated temperature reading in the evening does not definitively indicate a fever. Choice C is incorrect as there is no indication of incorrect temperature measurement. Choice D is incorrect as the temperature changes are not related to monthly hormones but rather to the body's natural daily rhythm.
What is the best outcome for a patient with the nursing diagnosis: Impaired social interaction related to sociocultural dissonance, as evidenced by stating, "Although I'd like to, I don't join in because I don't speak the language very well?"? The patient will:
- A. demonstrate improved social skills
- B. express a desire to interact with others
- C. become more independent in decision-making
- D. select and participate in one group activity per day
Correct Answer: D
Rationale: The correct outcome for the patient with impaired social interaction related to sociocultural dissonance is to select and participate in one group activity per day. This outcome focuses on increasing social involvement, which aligns with addressing the nursing diagnosis. The patient has already expressed a desire to interact with others, so the goal is to facilitate actual participation in social activities. Becoming more independent in decision-making and demonstrating improved social skills are not directly related to the specific nursing diagnosis provided. Additionally, the outcomes must be measurable, making choices A and C less appropriate as they lack specificity and measurability.
