NCLEX RN Exam Review Answers
1. A patient is being admitted to the ICU with a severe case of encephalitis. Which of these drugs would the nurse not expect to be prescribed for this condition?
- A. Acyclovir (Zovirax)
- B. Mannitol (Osmitrol)
- C. Lactated Ringer's
- D. Phenytoin (Dilantin)
Correct answer: C
Rationale: In the treatment of encephalitis, medications like Acyclovir and Phenytoin are commonly prescribed. Acyclovir is an antiviral medication used to treat viral infections like herpes simplex virus, which can cause encephalitis. Phenytoin is an antiepileptic drug that may be used to manage seizures associated with encephalitis. Mannitol is a diuretic used to reduce intracranial pressure (ICP) by decreasing cerebral edema. Lactated Ringer's solution, on the other hand, is primarily used in fluid replacement therapy and may not be indicated if a patient is at risk for high ICP, as excessive fluid administration could worsen cerebral edema and increase ICP.
2. When auscultating the patient's lungs during a shift assessment on a patient admitted in the early phase of heart failure, which finding would the nurse most likely hear?
- A. Continuous rumbling, snoring, or rattling sounds mainly on expiration
- B. Continuous high-pitched musical sounds on inspiration and expiration
- C. Discontinuous, high-pitched sounds of short duration heard on inspiration
- D. A series of long-duration, discontinuous, low-pitched sounds during inspiration
Correct answer: C
Rationale: In the early phase of heart failure, fine crackles are likely to be heard upon auscultation of the lungs. Fine crackles are characterized as discontinuous, high-pitched sounds of short duration heard on inspiration. Rhonchi are continuous rumbling, snoring, or rattling sounds mainly on expiration, which are often associated with airway secretions. Coarse crackles are a series of long-duration, discontinuous, low-pitched sounds during inspiration, typically indicating fluid in the alveoli. Wheezes are continuous high-pitched musical sounds on inspiration and expiration, commonly heard in conditions like asthma or chronic obstructive pulmonary disease (COPD). Therefore, the correct choice is C, as it describes the expected lung sounds in a patient with early heart failure.
3. A newborn has been diagnosed with hypothyroidism. In discussing the condition and treatment with the family, the nurse should emphasize:
- A. They can expect the child will be mentally retarded.
- B. Administration of thyroid hormone will prevent problems.
- C. This rare problem is always hereditary.
- D. Physical growth/development will be delayed.
Correct answer: B
Rationale: The correct answer is administration of thyroid hormone will prevent problems. In newborns diagnosed with hypothyroidism, early identification and continuous treatment with hormone replacement can correct this condition effectively. Choice A is incorrect as it uses outdated and inappropriate language (mentally retarded) and does not reflect modern understanding of conditions. Choice C is incorrect because while some cases of hypothyroidism can be hereditary, it is not always the case. Choice D is incorrect as physical growth and development can be affected by hypothyroidism, but the critical emphasis should be on the importance of administering thyroid hormone to prevent complications and support normal growth and development.
4. The nurse is reviewing the characteristics of culture. Which statement is correct regarding the development of one's culture?
- A. Learned through language acquisition and socialization.
- B. Genetically determined on the basis of racial background.
- C. A nonspecific phenomenon and is adaptive but unnecessary.
- D. Biologically determined on the basis of physical characteristics.
Correct answer: A
Rationale: Culture is a complex phenomenon that includes attitudes, beliefs, self-definitions, norms, roles, and values learned from birth through the processes of language acquisition and socialization. It is not biologically or genetically determined, but rather acquired through social interactions. The correct answer, 'Learned through language acquisition and socialization,' aligns with the understanding that culture is a learned behavior. Choices B, C, and D are incorrect because culture is not genetically determined, nonspecific, or biologically based on physical characteristics. Understanding that culture is acquired through language and socialization is essential for healthcare providers to provide culturally competent care.
5. The healthcare provider is caring for a 20 lbs (9 kg) 6-month-old with a 3-day history of diarrhea, occasional vomiting, and fever. Peripheral intravenous therapy has been initiated, with 5% dextrose in 0.33% normal saline with 20 mEq of potassium per liter infusing at 35 ml/hr. Which finding should be reported to the healthcare provider immediately?
- A. 3 episodes of vomiting in 1 hour
- B. Periodic crying and irritability
- C. Vigorous sucking on a pacifier
- D. No measurable voiding in 4 hours
Correct answer: D
Rationale: The correct answer is 'No measurable voiding in 4 hours.' This finding should be reported to the healthcare provider immediately. The concern is the possibility of hyperkalemia, which could occur with continued potassium administration and a decrease in urinary output since potassium is excreted via the kidneys. It is crucial to monitor urinary output in pediatric patients receiving potassium-containing IV solutions to prevent electrolyte imbalances and potential complications. Choices A, B, and C are not the most critical findings that require immediate reporting. '3 episodes of vomiting in 1 hour' may suggest a need for antiemetic therapy or further assessment of the underlying cause but does not pose an immediate risk like the potential electrolyte imbalance from decreased urinary output. 'Periodic crying and irritability' and 'Vigorous sucking on a pacifier' are common behaviors in infants and are not indicative of a critical condition that requires urgent attention in this scenario.
