Exam Cram NCLEX RN Practice Questions
1. The nurse is assessing an 8-year-old child whose growth rate measures below the third percentile for a child his age. He appears significantly younger than his stated age and is chubby with infantile facial features. Which condition does this child likely have?
- A. Acromegaly
- B. Marfan syndrome
- C. Hypopituitary dwarfism
- D. Achondroplastic dwarfism
Correct answer: C
Rationale: Hypopituitary dwarfism is caused by a deficiency in growth hormone in childhood and results in a retardation of growth below the third percentile, delayed puberty, and other problems. The child's appearance fits this description. Achondroplastic dwarfism is a genetic disorder resulting in characteristic deformities; Marfan syndrome is an inherited connective tissue disorder characterized by a tall, thin stature and other features. Acromegaly is the result of excessive secretion of growth hormone in adulthood which causes overgrowth of bone in the face, head, hands, and feet.
2. A client with expressive aphasia is pointing wildly at the bath water but unable to speak. Which response from the nurse is most appropriate?
- A. Is something wrong with the bath water?
- B. Just calm down, we'll finish your bath soon.
- C. Are you trying to tell me something?
- D. Shall I turn on the television?
Correct answer: A
Rationale: A client with expressive aphasia faces difficulty expressing themselves verbally but can understand others. In this scenario, the client's gestures indicate a communication attempt. The nurse's best response is to directly address the potential issue the client is indicating, which is the bath water. Option A acknowledges the client's non-verbal communication and seeks to address their concern. Choices B, C, and D do not directly address the client's attempt to communicate about the bath water, which is the focal point of the interaction.
3. The nurse is conducting a health fair for older adults. Which statement is true regarding vital sign measurements in aging adults?
- A. The pulse is easier to palpate due to the rigidity of the blood vessels.
- B. An increased respiratory rate and a shallower inspiratory phase are expected findings.
- C. A widened pulse pressure occurs from changes in the systolic and diastolic blood pressures.
- D. Changes in the body's temperature regulatory mechanism decrease the older adult's likelihood of developing a fever.
Correct answer: B
Rationale: Aging causes a decrease in vital capacity and decreased inspiratory reserve volume. As a result, the examiner may observe a shallower inspiratory phase and an increased respiratory rate in older adults. Contrary to common belief, the increased rigidity of arterial walls actually makes the pulse easier to palpate in aging adults. Pulse pressure is widened, not decreased, due to changes in systolic and diastolic blood pressures. Furthermore, changes in the body's temperature regulatory mechanism make older individuals less likely to develop a fever but more susceptible to hypothermia.
4. 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.
5. Which brain structure serves as the heat-regulating center?
- A. Hypothalamus
- B. Pituitary Gland
- C. Pons
- D. Medulla Oblongata
Correct answer: A
Rationale: The correct answer is the Hypothalamus. The hypothalamus is responsible for regulating body temperature, ensuring it stays within a narrow range. Moreover, the hypothalamus controls various essential bodily functions, such as hunger, thirst, and circadian rhythms. Choices B, C, and D are incorrect because the Pituitary Gland primarily produces and releases hormones, the Pons is involved in functions like sleep, respiration, and bladder control, and the Medulla Oblongata controls vital functions like breathing and heart rate, but not body temperature regulation.
