a patient who is blood type ab

NCLEX-RN

NCLEX RN Predictor Exam

1. For a patient who is blood type AB, which blood product can they receive?

A. Plasma from a type B donor
B. Whole blood from a type A donor
C. Packed RBCs from a type O donor
D. All of the above

Correct answer: C

Rationale: A patient with blood type AB has AB antigens on their red blood cells. This means they can only receive blood products that are compatible with these antigens. Choice A is incorrect because an AB patient cannot receive plasma from a type B donor due to the antibodies present in type B plasma. Choice B is incorrect because an AB patient cannot receive whole blood from a type A donor as it contains incompatible antigens. Choice C is the correct answer because an AB patient can receive packed RBCs from a type O donor. Type O donors have no A or B antigens, making their blood compatible for transfusion to recipients with any blood type. Therefore, choices A and B are incorrect, and the correct choice is C.

2. When performing CPR, at what rate should chest compressions be applied?

A. 100 per minute
B. 60 per minute
C. As quickly as possible
D. 200 per minute

Correct answer: A

Rationale: During CPR, chest compressions should be applied at a rate of 100 compressions per minute in order to effectively circulate blood and oxygen to vital organs. Option A, '100 per minute,' is the correct answer as it aligns with the recommended compression rate in CPR guidelines. Option B, '60 per minute,' is incorrect as it is too slow and may not provide adequate circulation. Option C, 'As quickly as possible,' is vague and does not specify the recommended compression rate. Option D, '200 per minute,' is incorrect as it exceeds the recommended rate and may not be as effective in maintaining perfusion.

3. When evaluating the temperature of older adults, what aspect should the healthcare provider remember about an older adult's body temperature?

A. The body temperature of the older adult is lower than that of a younger adult.
B. An older adult's body temperature is approximately the same as that of a young child.
C. Body temperature varies based on the type of thermometer used.
D. In older adults, body temperature can fluctuate widely due to less effective heat control mechanisms.

Correct answer: A

Rationale: When evaluating the temperature of older adults, it is important to note that their body temperature is usually lower than that of younger adults, with a mean temperature of 36.2°C. Choice B is incorrect because an older adult's body temperature is not approximately the same as that of a young child. Choice C is incorrect because body temperature is a physiological parameter and does not vary based on the type of thermometer used. Choice D is incorrect because while older adults may have less effective heat control mechanisms, their body temperature is typically lower, not widely fluctuating.

4. A nursing care plan states, 'Assist the patient to the bedside commode PRN.' When will this patient get this assistance to the commode?

A. Whenever needed
B. At bedtime
C. During the night
D. During the day

Correct answer: A

Rationale: The correct answer is 'Whenever needed.' The abbreviation 'PRN' stands for 'pro re nata,' which translates to 'as needed' or 'whenever necessary.' This means that the patient will receive assistance to the commode whenever they require it, based on their individual needs and condition. Choices B, C, and D are incorrect because 'PRN' does not specify a specific time like bedtime, during the night, or during the day; instead, it indicates assistance based on the patient's needs.

5. The nurse is examining a 2-year-old child and asks, "May I listen to your heart now?"? Which critique of the nurse's technique is most accurate?

A. Asking questions may enhance the child's autonomy.
B. Asking the child for permission helps develop a sense of trust.
C. This question is an inappropriate statement because children at this age like to have choices.
D. Children at this age like to say, "No."? The examiner should not offer a choice when no choice is available.

Correct answer: D

Rationale: Children at the age of 2 often like to assert their independence by saying "No."? In situations where there is actually no choice available, offering a false choice can lead to a lack of trust. It is important not to offer a choice when there isn't one, as doing so may undermine trust. While asking for permission can enhance autonomy and trust, offering a limited option like, "Shall I listen to your heart next or your tummy?"? may be a better approach. Therefore, the correct critique of the nurse's technique in this scenario is that children at this age tend to say "No,"? so the examiner should avoid offering a choice when there isn't a real alternative.
