NCLEX RN Predictor Exam
1. A patient has been told to monitor her LH levels. Which of the following potential conditions might the patient be suffering from?
- A. Menorrhagia
- B. Grave's Disease
- C. Menopause
- D. Infertility
Correct answer: D
Rationale: Luteinizing hormone (LH) is released by the pituitary gland to stimulate ovulation. One of the common reasons for monitoring LH levels is infertility. In women with infertility, LH levels are monitored to time intercourse accurately to maximize the chances of conception. Menorrhagia (choice A) is characterized by heavy menstrual bleeding and is not directly related to LH levels. Grave's Disease (choice B) is an autoimmune disorder affecting the thyroid gland and is not typically monitored by LH levels. Menopause (choice C) is a natural process marking the end of a woman's reproductive years and is not a condition where LH monitoring for infertility is common.
2. When measuring the vital signs of a 6-month-old infant, which action by the nurse is correct?
- A. Respirations are measured first, followed by pulse and temperature.
- B. Vital signs should be measured as frequently as in an adult.
- C. Procedures are explained to the parent, and the infant is encouraged to handle the equipment.
- D. The nurse should first measure the infant's vital signs before performing a physical examination.
Correct answer: A
Rationale: When assessing vital signs in a 6-month-old infant, the correct order is to measure respirations first, followed by pulse and temperature. This sequence is important to avoid potential alterations in respiratory and pulse rates caused by factors like crying or discomfort. Measuring the temperature first, especially rectally, may lead to an increase in respiratory and pulse rates, which can skew the results. It is crucial to follow this specific order to obtain accurate baseline values. Therefore, option A is the correct choice. Option B is incorrect as the frequency of measuring vital signs in infants differs based on individual needs rather than being consistently more frequent than in adults. Option C is not directly related to the correct sequence for measuring vital signs in infants. Option D is incorrect because the physical examination typically follows the assessment of vital signs in clinical practice.
3. Over a patient's lifespan, how does the pulse rate change?
- A. starts out fast and decreases as the patient ages.
- B. starts out slower and increases as the patient ages.
- C. varies from slow to fast throughout the lifespan.
- D. stays consistent from birth to death.
Correct answer: A
Rationale: The correct answer is that the pulse rate starts out fast and decreases as the patient ages. In infants, the normal pulse rate is around 140 beats per minute, which then falls to an average of 80 beats per minute in adults. As individuals age, their pulse rate tends to decrease due to changes in cardiovascular function. Choice B is incorrect as the pulse rate typically decreases with age, rather than increases. Choice C is incorrect as there is a general trend of decreasing pulse rate as individuals age, rather than a continuous variation. Choice D is incorrect as the pulse rate does change over a patient's lifespan, starting fast in infants and decreasing as they age.
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. All of the following factors may contribute to client falls EXCEPT:
- A. Contact dermatitis
- B. Urinary frequency
- C. Decreased visual acuity
- D. Confusion
Correct answer: A
Rationale: Client falls can result from various factors, both intrinsic and extrinsic. Intrinsic factors include health conditions like urinary frequency, which increases the need for bathroom visits, decreased visual acuity, and confusion. These factors can directly contribute to an increased risk of falls. However, contact dermatitis does not directly lead to falls. Contact dermatitis is a skin condition caused by contact with irritants or allergens and does not inherently predispose individuals to falling. Therefore, among the given options, contact dermatitis is the only factor that is not directly associated with an increased risk of falls.
