NCLEX RN Exam Review Answers
1. As a nursing supervisor in a long-term care facility, you prioritize strict infection control prevention measures due to the understanding that the normal aging process weakens the body's defenses. Which theory of aging supports the necessity of strict infection control prevention measures?
- A. The Programmed Longevity Theory
- B. The Immunological Theory of Aging
- C. The Endocrine Theory
- D. The Rate of Living Theory
Correct answer: B
Rationale: The theory of aging that aligns with the need for strict infection control prevention measures is the Immunological Theory of Aging. This theory posits that aging leads to a decline in the body's immune defenses and a reduced ability of antibodies to protect against infections. The other theories do not directly address the impact of aging on the immune system. The Programmed Longevity Theory focuses on genetic changes affecting aging, the Endocrine Theory emphasizes hormonal changes, and the Rate of Living Theory relates longevity to the rate of oxygen metabolism.
2. What action by the nurse will be most effective in decreasing the spread of pertussis in a community setting?
- A. Providing supportive care to patients diagnosed with pertussis
- B. Teaching family members about the importance of careful handwashing
- C. Teaching patients about the necessity of adult pertussis immunizations
- D. Encouraging patients to complete the prescribed course of antibiotics
Correct answer: C
Rationale: The most effective action by the nurse to decrease the spread of pertussis in a community setting is to teach patients about the necessity of adult pertussis immunizations. The increased rate of pertussis in adults is often attributed to waning immunity after childhood immunization. Immunization is highly effective in protecting communities from infectious diseases. While teaching about handwashing is important for overall infection control, pertussis is primarily spread through respiratory droplets and contact with secretions. Providing supportive care does not significantly impact the disease course or transmission risk. Encouraging completion of antibiotics may help reduce transmission, but patients likely have already spread the disease by the time the diagnosis is made. Therefore, the emphasis should be on prevention through immunization to reduce the spread of pertussis.
3. Mrs. M has had diabetes for seven years. She has worked hard to control her blood glucose levels and watch her dietary intake. Her physician orders a hemoglobin A1C test. Which of the following best describes the action of this test?
- A. The test determines if the client is anemic and needs iron supplements
- B. The test determines if there is excess glucose building up in the urine
- C. The test determines the amount of hemoglobin reaching the liver to support gluconeogenesis
- D. The test determines the amount of hemoglobin that is coated with glucose
Correct answer: D
Rationale: A hemoglobin A1C test, also known as a glycated hemoglobin test, determines the amount of hemoglobin that is coated with glucose. Excess glucose in the bloodstream may cause it to attach to hemoglobin on red blood cells. Because the life of these cells is between 2 and 3 months, the hemoglobin A1C is an accurate measurement of a client's glucose during that time. Choices A, B, and C are incorrect. Choice A relates to anemia and iron supplements, which are not assessed by a hemoglobin A1C test. Choice B mentions excess glucose in the urine, which is typically assessed through a urine glucose test, not the hemoglobin A1C test. Choice C is incorrect as the test is not related to the amount of hemoglobin reaching the liver to support gluconeogenesis; instead, it specifically measures the amount of hemoglobin that is glycated or coated with glucose.
4. Which action represents the evaluation stage of the plan of care?
- A. The nurse assigns a nursing diagnosis of Impaired Skin Integrity related to diminished skin circulation
- B. The nurse assesses the client's vital signs and asks about symptoms
- C. The nurse determines that the client is not meeting his set outcomes and makes revisions
- D. The nurse discusses the client's health history
Correct answer: C
Rationale: The correct answer is C. The evaluation stage of the nursing process involves reviewing the assessments, diagnoses, and interventions given to the client and then determining if the client is meeting expected outcomes. In this scenario, the nurse is assessing whether the client is meeting the outcomes set for their care plan and making revisions as needed. Choice A is incorrect as assigning a nursing diagnosis is part of the nursing diagnosis phase, not the evaluation phase. Choice B represents the assessment phase of the nursing process, not the evaluation phase. Choice D involves discussing the client's health history, which is more aligned with the assessment phase rather than the evaluation phase.
5. The nurse is providing disease prevention education to a 63-year-old woman with a negative family history of breast cancer. The nurse recommends the patient schedule mammograms with which frequency?
- A. Every 5 years
- B. Every 10 years
- C. Every other year
- D. Once a year
Correct answer: C
Rationale: Mammograms, along with breast self-examinations and other routine tests, are key for the early diagnosis and treatment of breast cancer. All major societies (WHO, ACS, USPSTF) recommend a screening mammogram every two years in women of this age at average risk of breast cancer. The recommended frequency may change if there are identified family history and significant risk factors. Choosing 'Once a year' is too frequent and not aligned with current guidelines. Opting for 'Every 5 years' or 'Every 10 years' intervals is not adequate for regular breast cancer screening and may increase the risk of cancer progression. Therefore, 'Every other year' is the most appropriate choice for this patient without a family history of breast cancer.
