NCLEX RN Predictor Exam

1. When are manual hematocrits done?

A. to monitor anemia
B. by using a microhematocrit tube.
C. to measure the percentage of plasma to cells.
D. All of the above.

Correct answer: D

Rationale: Manual hematocrits are performed to monitor anemia, which involves measuring the percentage of red blood cells in the blood. The process involves collecting blood in a microhematocrit tube, then centrifuging it to separate the plasma from the cells. By measuring the ratio of plasma to cells, healthcare providers can assess the patient's hematocrit level. Therefore, all the provided options are correct as they collectively describe the purpose and procedure of manual hematocrits.

2. What action by the nurse is appropriate when examining a 16-year-old male teenager?

A. Discuss health teaching with the teenager to promote wellness.
B. Ask the parent to step out of the room during the history and physical examination to respect the teenager's privacy.
C. Use age-appropriate communication when speaking to the teenager to ensure understanding.
D. Provide feedback that his body is developing normally and discuss the wide variation among teenagers on the rate of growth and development.

Correct answer: D

Rationale: During the examination of a 16-year-old male teenager, it is essential to provide feedback that his body is developing normally and to discuss the wide variation among teenagers regarding growth and development. This reassures the teenager about his health status and addresses any concerns about physical development. It is important to recognize that adolescents are very conscious of their body image and often compare themselves to their peers, hence the need for such feedback. Asking the parent to step out of the room respects the teenager's privacy and promotes open communication between the nurse and the teenager. Using age-appropriate communication is crucial to ensure that the teenager understands the information provided. Asking the parent to stay in the room may not be ideal as it can inhibit open discussion, and talking to the teenager as if they were a younger child is inappropriate and may undermine their autonomy and understanding.

3. Which is the most effective action for controlling the spread of infection?

A. Thorough hand hygiene
B. Wearing gloves and masks when providing direct client care
C. Implementing appropriate isolation precautions
D. Administering broad-spectrum prophylactic antibiotics

Correct answer: A

Rationale: Thorough hand hygiene is the most effective action for controlling the spread of infection as hands are a common source of transmission. Regular and routine hand hygiene helps prevent the movement of potentially infective materials. Wearing gloves and masks is important when providing direct client care to protect both the caregiver and the patient, but it is not as effective as thorough hand hygiene in preventing overall infection spread. Implementing appropriate isolation precautions is necessary for clients with known communicable diseases, but it is not as universally effective in preventing the spread of various infections. Administering broad-spectrum prophylactic antibiotics is not an appropriate measure for controlling the spread of infection as routine use can lead to superinfection and the development of resistant organisms.

4. After a symptom is recognized, the first effort at treatment is often self-treatment. Which of the following statements is true about self-treatment?

A. "Not recognized as valuable by most health care providers."?
B. "Usually ineffective and may delay more effective treatment."?
C. "Always less expensive than biomedical alternatives."?
D. "Influenced by the accessibility of over-the-counter medicines."?

Correct answer: D

Rationale: After a symptom is identified, the first effort at treatment is often self-treatment. The availability of over-the-counter medications, the relatively high literacy level of Americans, and the influence of the internet and mass media in communicating health-related information to the general population have contributed to the high percentage of cases of self-treatment. Health care providers are recognizing the value of a wide variety of alternative, complementary, and traditional interventions. Many self-treatments, such as over-the-counter medications, are effective. Self-treatment is not always less expensive. Choice A is incorrect as health care providers are recognizing the value of self-treatment. Choice B is incorrect because self-treatment can be effective in many cases. Choice C is incorrect as self-treatment is not always less expensive; it depends on the specific treatment being used.

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

A. dynia and -algia
B. a- and an
C. ia and -ac
D. pathy and -osis

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.
