NCLEX RN Exam Review Answers
1. As you are assessing the fetus during labor, you are determining the fetal lie, presentation, attitude, station, and position. Your client asks you what all these assessments are. Among other things, how should you respond to the mother?
- A. You should explain that fetal lie is where the fetus's presenting part is within the birth canal during labor, among other information about the other assessments.
- B. You should explain that fetal presentation is the relationship of the fetus's spine to the mother's spine, among other information about the other assessments.
- C. You should explain that fetal attitude is the relationship of the fetus's presenting part to the anterior, posterior, right, or left side of the mother's pelvis, among other information about the other assessments.
- D. You should explain that fetal station is the level of the fetus's presenting part in relationship to the mother's ischial spines, among other information about the other assessments.
Correct answer: D
Rationale: You should explain that fetal station is the level of the fetus's presenting part in relationship to the mother's ischial spines. Fetal station is measured in terms of the number of centimeters above or below the mother's ischial spines. When the fetus is 1 to 5 centimeters above the ischial spines, the fetal station is -1 to -5, and when the fetus is 1 to 5 centimeters below the level of the maternal ischial spines, the fetal station is +1 to +5. Choices A, B, and C provide incorrect information about fetal lie, presentation, and attitude, respectively, which do not align with the definitions of these terms in obstetrics.
2. Mrs. G is seen for follow-up after testing for chronically high blood glucose levels. Her physician diagnoses her with type 1 diabetes. Which of the following information is part of this client's education about this condition?
- A. Type 1 diabetes occurs due to increased carbohydrate intake and lack of exercise
- B. Type 1 diabetes is managed through diet and exercise
- C. Type 1 diabetes is caused by destruction of beta cells in the pancreas
- D. Type 1 diabetes leads to the body's cells rejecting insulin
Correct answer: C
Rationale: Type 1 diabetes is an autoimmune condition where the immune system attacks and destroys the beta cells in the pancreas, leading to a lack of insulin production. Insulin is essential for regulating blood glucose levels and enabling cells to use glucose for energy. Understanding that type 1 diabetes results from the destruction of beta cells helps patients comprehend the need for insulin replacement therapy. Choices A and B are incorrect as type 1 diabetes is not primarily caused by diet or exercise habits. Choice D is incorrect because type 1 diabetes is not about the body's cells rejecting insulin but rather the lack of insulin production due to beta cell destruction.
3. Mr. N is a client who entered the hospital with a diagnosis of diabetic ketoacidosis. The nurse enters his room to check his vital signs and finds him breathing at a rate of 32 times per minute; his respirations are deep and regular. Which type of respiratory pattern is Mr. N most likely exhibiting?
- A. Kussmaul respirations
- B. Cheyne-Stokes respirations
- C. Biot's respirations
- D. Cluster breathing
Correct answer: A
Rationale: Mr. N is exhibiting Kussmaul respirations, characterized by rapid, deep, and regular breathing. This type of respiratory pattern is commonly seen in metabolic acidosis, such as in diabetic ketoacidosis. Kussmaul respirations are a form of hyperventilation, leading to the elimination of carbon dioxide from the body. Choice B, Cheyne-Stokes respirations, is characterized by alternating periods of deep, rapid breathing followed by periods of apnea and is not typically associated with diabetic ketoacidosis. Choice C, Biot's respirations, involve irregular breathing patterns with periods of apnea and are not reflective of the described breathing pattern. Cluster breathing, as mentioned in Choice D, is not a recognized term in respiratory patterns and does not describe the breathing pattern observed in Mr. N.
4. The nurse practicing in a maternity setting recognizes that the postmature fetus is at risk due to:
- A. Excessive fetal weight
- B. Low blood sugar levels
- C. Depletion of subcutaneous fat
- D. Progressive placental insufficiency
Correct answer: D
Rationale: A postmature or postterm pregnancy occurs when a pregnancy exceeds the typical term of 38 to 42 weeks. In this situation, the fetus is at risk due to progressive placental insufficiency. This occurs because the placenta loses its ability to function effectively after 42 weeks. The accumulation of calcium deposits in the placenta reduces blood perfusion, oxygen supply, and nutrient delivery to the fetus, leading to potential growth problems. Choices A, B, and C are incorrect because excessive fetal weight, low blood sugar levels, and depletion of subcutaneous fat are not the primary risks associated with postmature fetuses. The main concern lies in the compromised placental function and its impact on fetal well-being.
5. 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.
