Nclex Exam Cram Practice Questions
1. What is the most likely reason for a hospitalized adult client who routinely works from midnight until 8 a.m. to have a temperature of 99.1�F at 4 a.m.?
- A. delta sleep
- B. slow brain waves
- C. pneumonia
- D. circadian rhythm
Correct answer: D
Rationale: The correct answer is 'circadian rhythm.' Circadian rhythms are biological cycles that last about 24 hours. The sleep-wake cycle is closely tied to circadian rhythms, affecting body temperature. Normally, core body temperature drops during sleep, reaching its 24-hour low around 4 a.m. In this case, the client's temperature of 99.1�F at 4 a.m. is likely due to the disruption of their circadian rhythm caused by working from midnight until 8 a.m. Choices A, B, and C are incorrect because delta sleep, slow brain waves, and pneumonia do not directly explain the temperature fluctuation based on circadian rhythm.
2. Which of the following neurological disorders is characterized by writhing, twisting movements of the face and limbs?
- A. epilepsy
- B. Parkinson's
- C. multiple sclerosis
- D. Huntington's chorea
Correct answer: D
Rationale: Huntington's chorea is characterized by writhing, twisting movements of the face and limbs, known as chorea. This disorder is caused by a genetic mutation affecting specific brain cells. Epilepsy presents with seizures, Parkinson's with tremors and rigidity, and multiple sclerosis with central nervous system issues. The specific description of writhing and twisting movements aligns with Huntington's chorea, making it the correct answer. Choices A, B, and C are incorrect as they describe different neurological disorders with distinct symptoms that do not match the writhing, twisting movements characteristic of Huntington's chorea.
3. The nurse has completed client teaching about introducing solid foods to an infant. To evaluate teaching, the nurse asks the mother to identify an appropriate first solid food. Which of the following is an appropriate response?
- A. pureed canned squash
- B. pureed apples
- C. yogurt
- D. infant rice cereal
Correct answer: D
Rationale: The correct answer is infant rice cereal. Single-grain infant cereals are recommended as the first solid food because they are easily digestible and have added iron content. Choice C, yogurt, is incorrect because yogurt is a milk product and should be delayed until the child is 12 months old due to the risk of milk allergy. Choices A and B are incorrect because fruits and vegetables are typically introduced after cereals to help the infant get accustomed to solid foods gradually.
4. A test that can correctly identify those who do not have a given disease is:
- A. specific.
- B. sensitive.
- C. negative culture.
- D. marginal finding.
Correct answer: A
Rationale: The correct answer is 'specific.' A specific test correctly identifies individuals who do not have a particular disease. In this case, since the lab culture report is negative for the suspected infection, it means the test is good at ruling out the disease. 'Sensitive' (choice B) would be incorrect as sensitivity refers to a test's ability to correctly identify individuals who do have the disease. 'Negative culture' (choice C) is incorrect as it describes the result rather than the test's characteristic. 'Marginal finding' (choice D) is unrelated to the concept of correctly identifying individuals without the disease.
5. A gastroenterologist should be consulted for clients suffering from:
- A. digestive system diseases
- B. urinary system diseases
- C. female reproductive system diseases
- D. nervous system diseases
Correct answer: A
Rationale: A gastroenterologist specializes in treating diseases and disorders of the digestive system, including the stomach, intestines, liver, and pancreas. Therefore, clients with digestive system diseases should consult a gastroenterologist. Choices B, C, and D are incorrect because urinary system diseases are managed by urologists, female reproductive system diseases by gynecologists, and nervous system diseases by neurologists.
