NCLEX RN Exam Review Answers
1. What is the expected date of delivery for your pregnant client when her last menstrual period was on 10/20/2016
- A. 7/7/2017
- B. 8/7/2017
- C. 6/7/2017
- D. 8/1/2017
Correct answer: A
Rationale: The expected date of delivery is calculated using Nagle's rule which is: The first day of last menstrual period - 3 months + 7 days = the estimated date of delivery
2. A client has entered disseminated intravascular coagulation (DIC) after becoming extremely ill after surgery. Which of the following laboratory findings would the nurse expect to see with this client?
- A. Elevated fibrinogen level
- B. Prolonged PT
- C. Elevated platelet count
- D. Depressed d-dimer level
Correct answer: B
Rationale: In disseminated intravascular coagulation (DIC), a client experiences widespread clotting throughout the body, leading to the depletion of clotting factors and platelets. A prolonged prothrombin time (PT) is a common finding in DIC. The PT measures the extrinsic pathway of the clotting cascade and reflects how quickly blood can clot. In DIC, the consumption of clotting factors results in a prolonged PT, indicating impaired clotting ability. Elevated fibrinogen levels (Choice A) are typically seen in the early stages of DIC due to the body's attempt to compensate for clot breakdown. Elevated platelet count (Choice C) is not a typical finding in DIC as platelets are consumed during the widespread clotting. A depressed d-dimer level (Choice D) is also not expected in DIC as d-dimer levels are elevated due to the breakdown of fibrin clots. Therefore, the correct answer is a prolonged PT.
3. The chain of infection includes the ________________.
- A. germ, agent, reservoir, exit portal, mode of transmission, entry port, and susceptible host
- B. active natural, active artificial, passive natural, and passive artificial
- C. opportunism, weakness, immunity, and colonization
- D. intrinsic, extrinsic, internal, and external transmission
Correct answer: A
Rationale: The chain, or cycle, of infection includes the germ (microorganism), agent, reservoir, exit portal, mode of transmission, entry port, and susceptible host. This sequence describes how infections are passed from one person to another. Choice B is incorrect because it refers to types of immunity, not components of the chain of infection. Choice C is also incorrect as it lists terms unrelated to the chain of infection. Choice D is incorrect as it describes transmission types, not components of the chain of infection. Understanding the chain of infection is crucial in preventing the spread of infections by breaking one or more links in the chain, such as interrupting the mode of transmission through proper hand hygiene.
4. You are creating a teaching plan for a patient with newly diagnosed migraine headaches. Which key item should NOT be included in the teaching plan?
- A. Avoid foods that contain tyramine, such as alcohol and aged cheese.
- B. Avoid drugs such as Tagamet, nitroglycerin, and Nifedipine.
- C. Continue taking estrogen as prescribed by your physician.
- D. A potential side effect of medications is rebound headache.
Correct answer: C
Rationale: The correct answer is C: Continue taking estrogen as prescribed by your physician. Medications such as estrogen supplements may actually trigger a migraine headache attack. Fluctuations in estrogen, such as before or during menstrual periods, pregnancy, and menopause, seem to trigger headaches in many women. Choices A and B are important to include in the teaching plan for a patient with migraines as avoiding foods containing tyramine and certain drugs can help prevent migraine triggers. Choice D is also relevant as it is essential for the patient to be aware of potential side effects of medications, including rebound headaches.
5. 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.
