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. Who should be members of a patient care conference?

A. Doctors, nurses, and nursing assistants since they are healthcare providers
B. Doctors, nurses, and the patient and/or the family members
C. ALL members of the healthcare team
D. ALL members of the healthcare team and the patient/resident

Correct answer: D

Rationale: In a patient care conference, it is essential to have all members of the healthcare team present to ensure comprehensive and coordinated care. Including the patient or resident, along with their family members if desired, is crucial as they are the focus of care. Choice A is incorrect because it excludes other important members of the healthcare team. Choice B is partially correct as it includes the patient and/or family members but does not encompass the entire healthcare team. Choice C is too broad and does not specifically address the inclusion of the patient or resident. The correct answer, Choice D, includes all healthcare team members and the patient/resident, ensuring a holistic approach to patient-centered care.

3. During an examination of a patient's abdomen, the nurse notes that the abdomen is rounded and firm to the touch. During percussion, the nurse notes a drum-like quality of the sounds across the quadrants. How would the nurse interpret this type of sound?

A. Constipation
B. Air-filled areas
C. Presence of a tumor
D. Presence of dense organs

Correct answer: B

Rationale: A musical or drum-like sound (tympany) is heard when percussion occurs over an air-filled viscus, such as the stomach or intestines. This indicates the presence of air-filled areas. Constipation, choice A, does not produce specific percussion sounds and is related to bowel movements rather than the sound produced during percussion. The presence of a tumor, choice C, would not typically produce a drum-like sound but might result in dullness or decreased resonance. Dense organs, choice D, would produce a dull thud sound rather than a drum-like tympanic sound.

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 statement best describes evidence-based practice?

A. Reading and analyzing research reports to determine their implementation in nursing practice
B. Collecting data to evaluate the efficiency of nursing practice in delivering quality care
C. Monitoring unit practices to ensure adherence to Joint Commission standards
D. Using the most effective, current, and applicable information to guide nursing care for the best outcomes

Correct answer: D

Rationale: Evidence-based practice involves utilizing the most effective, current, and relevant information to inform nursing care decisions for optimal client outcomes. While research reports and data collection are important components of evidence-based practice, the essence lies in integrating all available information to determine the best course of action. Monitoring compliance with standards, as described in choices A and C, is essential for quality assurance but does not capture the comprehensive nature of evidence-based practice.
