NCLEX RN Predictor Exam

1. A urine pregnancy test:

Correct answer: A

Rationale: A urine pregnancy test detects HCG in a pregnant woman's urine. Blood levels of HCG are usually higher and register earlier than HCG levels in the urine. Choice A is correct because urine pregnancy tests may be negative even if a blood pregnancy test is positive due to the differences in HCG levels in blood and urine. Choice B is incorrect because a urine pregnancy test can be positive throughout pregnancy, not just in the first trimester. Choice C is incorrect because LH (luteinizing hormone) is not the hormone detected in a pregnancy test; it is HCG (human chorionic gonadotropin). Choice D is incorrect because not all the statements provided are true.

2. Which of the following sets of word parts means 'Pain'?

Correct answer: A

Rationale: The correct answer is 'dynia and -algia.' The word parts 'dynia' and '-algia' specifically relate to pain. 'Dynia' refers to pain, and '-algia' also denotes pain. Therefore, when combined, they form the meaning 'pain.' Choices B, C, and D are incorrect because 'a-' and 'an' do not relate to pain, 'ia' and '-ac' do not specifically convey pain, and 'pathy' and '-osis' are not word parts that directly signify pain.

3. The healthcare professional has collected the following information on a patient: palpated blood pressure"?180 mm Hg; auscultated blood pressure"?170/100 mm Hg; apical pulse"?60 beats per minute; radial pulse"?70 beats per minute. What is the patient's pulse pressure?

Correct answer: B

Rationale: Pulse pressure is the numerical difference between the systolic and diastolic blood pressure readings. In this case, the systolic blood pressure is 170 mm Hg, and the diastolic blood pressure is 100 mm Hg. Therefore, the pulse pressure is calculated as 170 - 100 = 70 mm Hg. Pulse pressure reflects the stroke volume, the amount of blood ejected from the heart with each beat. Choices A, C, and D are incorrect because they do not accurately represent the difference between the systolic and diastolic blood pressure readings provided.

4. The nurse is conducting a health fair for older adults. Which statement is true regarding vital sign measurements in aging adults?

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.

5. The instructor is teaching a class on basic assessment skills. Which of the following statements is true regarding the stethoscope and its use?

Correct answer: B

Rationale: The stethoscope does not magnify sound but effectively blocks out extraneous room noises. The correct orientation of the earpieces is with the slope pointing forward toward the examiner's nose, not posteriorly. The tubing length of a stethoscope should ideally be between 14 to 18 inches (36 to 46 cm) to avoid sound distortion. Using tubing longer than this range can distort sound. Both the fit and quality of the stethoscope are crucial for accurate auscultation and assessment, highlighting their significance in clinical practice. Therefore, the correct answer is that the stethoscope blocks out extraneous room noise but does not magnify sound.
