NCLEX RN Exam Review Answers
1. The healthcare provider assesses a patient suspected of having an asthma attack. Which of the following is a common clinical manifestation of this condition?
- A. Audible crackles and orthopnea
- B. An audible wheeze and use of accessory muscles
- C. Audible crackles and use of accessory muscles
- D. Audible wheeze and orthopnea
Correct answer: B
Rationale: Choice B, 'An audible wheeze and use of accessory muscles,' is the correct answer. In asthma, patients commonly present with wheezing due to airway constriction and the use of accessory muscles to aid in breathing. Audible crackles (rales) are more commonly associated with conditions like pneumonia, congestive heart failure, or pulmonary fibrosis. Orthopnea, which is difficulty breathing while lying flat, is typically seen in conditions like heart failure or chronic obstructive pulmonary disease, rather than asthma. Choice C is incorrect as crackles are not a typical finding in asthma. Choice D is incorrect as orthopnea is not a common clinical manifestation of asthma.
2. A 20-year-old female attending college is found unconscious in her dorm room. She has a fever and a noticeable rash. She has just been admitted to the hospital. Which of the following tests is most likely to be performed first?
- A. Blood sugar check
- B. CT scan
- C. Blood cultures
- D. Arterial blood gases
Correct answer: C
Rationale: The most likely test to be performed first in this scenario is blood cultures. Blood cultures are crucial to investigate the fever and rash symptoms in an unconscious patient. This test is used to detect foreign invaders like bacteria, yeast, and other microorganisms in the blood, which could indicate a blood infection (bacteremia). A positive blood culture result confirms the presence of bacteria in the blood. A blood sugar check (choice A) may be important but is less likely to be the first test in this context. A CT scan (choice B) and arterial blood gases (choice D) are generally not the initial tests performed to investigate a fever and rash with altered mental status.
3. What is the likely cause of pericarditis in a young patient?
- A. Heart failure
- B. Acute MI
- C. Hypertension
- D. Infectious processes
Correct answer: D
Rationale: In younger patients, pericarditis is typically caused by an infection commonly triggered by viruses like the Coxsackie virus, streptococcus, staphylococcus, or Haemophilus influenzae. Infectious processes are the leading cause of pericarditis in younger individuals. Heart failure, Acute MI, and Hypertension are not common causes of pericarditis in young patients. In older adults, acute myocardial infarction (MI) is a more common cause of pericarditis.
4. A mother has recently been informed that her child has Down syndrome. You will be assigned to care for the child at shift change. Which of the following characteristics is not associated with Down syndrome?
- A. Simian crease
- B. Brachycephaly
- C. Oily skin
- D. Hypotonicity
Correct answer: C
Rationale: Individuals with Down syndrome commonly have certain physical characteristics, such as a simian crease (single transverse palmar crease), brachycephaly (shortened front-to-back skull dimension), and hypotonicity (low muscle tone). Oily skin is not a characteristic associated with Down syndrome; instead, individuals with Down syndrome often have dry skin. Therefore, oily skin is the correct answer in this context.
5. The nurse is caring for a 10-year-old on admission to the burn unit. One assessment parameter that will indicate that the child has adequate fluid replacement is:
- A. Urinary output of 30 ml per hour
- B. No complaints of thirst
- C. Increased hematocrit
- D. Good skin turgor around burn
Correct answer: A
Rationale: For a child of this age, this is adequate output, yet does not suggest overload. Disruption of sodium-ATPase activity presumably causes an intracellular sodium shift which contributes to hypovolemia and cellular edema. Heat injury also initiates the release of inflammatory and vasoactive mediators. These mediators are responsible for local vasoconstriction, systemic vasodilation, and increased transcapillary permeability. Increase in transcapillary permeability results in a rapid transfer of water, inorganic solutes, and plasma proteins between the intravascular and interstitial spaces.
