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. A client with adrenal insufficiency has a potassium level of 7.2 mEq/L. Which of the following signs or symptoms might the client exhibit with this result?
- A. Peaked T waves on the ECG
- B. Muscle spasms
- C. Constipation
- D. A prominent U wave on the ECG
Correct answer: A
Rationale: A client with hyperkalemia may exhibit peaked T waves on an electrocardiogram. This manifestation is an early sign of high potassium levels, but diagnosis should not be based on this aspect alone. Untreated, hyperkalemia can lead to progressively worsening cardiac instability. Muscle spasms (Choice B) are more commonly associated with hypocalcemia. Constipation (Choice C) is not a typical sign of hyperkalemia. A prominent U wave on the ECG (Choice D) is associated with hypokalemia, not hyperkalemia.
3. A client is being monitored for decreased tissue perfusion and increased risk of skin breakdown. Which measure best improves tissue perfusion in this client?
- A. Massaging the reddened areas
- B. Performing range of motion exercises
- C. Administering antithrombotics as ordered
- D. Feeding the client a high-carbohydrate diet
Correct answer: B
Rationale: For a client at risk of impaired skin integrity due to decreased tissue perfusion, improving mobility is crucial to enhance tissue perfusion and prevent skin breakdown. Range of motion exercises are beneficial to increase circulation and prevent complications. Massaging reddened areas may further damage fragile skin. Administering antithrombotics may be necessary for specific conditions but does not directly address tissue perfusion. Feeding a high-carbohydrate diet does not directly improve tissue perfusion in this context.
4. Because of budget cuts in the hospital, the nursing manager informs the staff that they must either rotate to other units more often or take their turns staying home from work. Which principle is this nurse manager demonstrating?
- A. Justice
- B. Paternalism
- C. Veracity
- D. Fraternity
Correct answer: D
Rationale: Veracity involves truth-telling, even in challenging situations. In this scenario, the nurse manager is being transparent about the need for staff to rotate units or take turns staying home due to budget cuts. This allows the staff to make informed decisions about their work schedules and potential impact on their pay and work areas. Option A, Justice, does not apply as the focus is on communication and transparency, not fairness. Option B, Paternalism, does not fit as it involves decisions made for others' well-being without their input, which is not the case here. Option D, Fraternity, pertains to unity among individuals, which is not the principle demonstrated by the nurse manager in this situation.
5. An infant is brought to the clinic by his mother, who has noticed that he holds his head in an unusual position and always faces to one side. Which of the following is the most likely explanation?
- A. Torticollis, with shortening of the sternocleidomastoid muscle
- B. Craniosynostosis, with premature closure of the cranial sutures
- C. Plagiocephaly, with flattening of one side of the head
- D. Hydrocephalus, with increased head size
Correct answer: A
Rationale: The correct answer is torticollis, characterized by the shortening of the sternocleidomastoid muscle, limiting the range of motion of the neck and causing the chin to point to the opposing side. Craniosynostosis is the premature closure of cranial sutures, leading to an abnormal head shape but not necessarily affecting head position. Plagiocephaly is flattening of one side of the head due to external forces or positioning, not muscle shortening. Hydrocephalus presents with an increased head size due to the accumulation of cerebrospinal fluid, not with a fixed head position.
