Exam Cram NCLEX RN Practice Questions
1. 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.
2. While caring for a client in labor, a nurse attaches an electronic fetal monitor to the client's abdomen to assess the baby's heart rate. The nurse observes that the baby's heart rate slows down during each contraction and does not return to normal limits until after the contraction is complete. What type of fetal heart rate change does this pattern describe?
- A. Variable decelerations
- B. Late decelerations
- C. Early decelerations
- D. Accelerations
Correct answer: B
Rationale: Late decelerations are characterized by the baby's heart rate declining in utero during contractions. The heart rate drops below baseline and stays low until after the contraction ends. Late decelerations are concerning as they indicate uteroplacental insufficiency, which can compromise fetal oxygenation. This pattern is a non-reassuring sign and requires immediate intervention. Variable decelerations are typically abrupt decreases in heart rate, often associated with cord compression. Early decelerations, on the other hand, mirror the contractions and are considered benign, resulting from fetal head compression. Accelerations are reassuring signs of fetal well-being, indicating a responsive and healthy fetal nervous system.
3. Which of the following is an example of the intervention phase of the individualized nursing care plan for a client who receives a colostomy after a bowel resection?
- A. Taking a health history and performing a physical exam prior to the procedure
- B. Instructing the client about how to care for his colostomy stoma
- C. Developing goals that state the client will ambulate three times a day
- D. Determining that the client may need more support at home after dismissal
Correct answer: B
Rationale: The intervention stage of the individualized nursing care plan is where the nurse provides care, treatments, or education to help the client meet the devised outcomes. Instructing the client about how to care for his colostomy stoma is the correct example of an intervention as it directly involves providing education and guidance to the client on post-operative care. This intervention supports the process of helping the client meet the outcomes designed for this case, which is to enable the client to properly care for his colostomy after a bowel resection. The other options do not directly involve interventions aimed at assisting the client in meeting the specific care needs related to the colostomy procedure.
4. 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 most likely exhibiting Kussmaul respirations. Kussmaul respirations are a form of hyperventilation associated with conditions like metabolic acidosis. They are characterized by rapid, regular, and deep breathing. This type of respiratory pattern helps the body compensate for metabolic acidosis by attempting to blow off excess carbon dioxide. This pattern is different from Cheyne-Stokes respirations (choice B), which are characterized by alternating periods of deep, rapid breathing followed by apnea. Biot's respirations (choice C) are characterized by groups of quick, shallow inspirations followed by irregular periods of apnea, and Cluster breathing (choice D) involves clusters of breaths followed by periods of apnea, often seen in patients with brain injury or neurological conditions.
5. Mrs. O is seen for follow-up after an episode of acute pancreatitis. Her physician orders a serum amylase level and the result is 200 U/L. Which of the following is a potential cause of this result?
- A. The client is pregnant
- B. The client has hypertension
- C. The client is in renal failure
- D. The client has pancreatitis
Correct answer: D
Rationale: An elevated serum amylase level after pancreatitis may indicate another attack of the condition. It is common to order serum amylase as part of routine follow-up after pancreatitis. Elevated levels can also be seen in related gastrointestinal conditions like cholecystitis or an intestinal blockage. Therefore, in this case, the most likely cause of the elevated serum amylase level is a recurrence or ongoing pancreatitis. The other options, including pregnancy, hypertension, and renal failure, are not typically associated with an elevated serum amylase level in the context of follow-up after acute pancreatitis.
