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. A patient is being treated in the Neurology Unit for Meningitis. Which of these is a priority assessment for the nurse to make?

A. Assess the patient for nuchal rigidity
B. Determine the patient's past exposure to infectious organisms
C. Check the patient's WBC lab values
D. Monitor for increased lethargy and drowsiness

Correct answer: D

Rationale: Monitoring for increased lethargy and drowsiness is crucial as these symptoms indicate a decreased level of consciousness, which is the cardinal sign of increased Intracranial Pressure (ICP). Elevated ICP can lead to serious complications and requires immediate intervention. Assessing for nuchal rigidity is important in suspected cases of meningitis but monitoring lethargy and drowsiness takes precedence due to its direct correlation with ICP. Determining past exposure to infectious organisms and checking WBC lab values are important for diagnosing and treating meningitis but do not directly address the immediate concern of increased ICP.

3. Why is it important to genotype HCV before initiating drug therapy?

A. Side effects of nucleotide analogs
B. Measures for improving the appetite
C. Ways to increase activity and exercise
D. Administering alpha-interferon (Intron A)

Correct answer: B

Rationale: Genotyping of HCV plays a crucial role in managing treatment as it helps determine the most effective therapy for the specific viral strain. It allows healthcare providers to personalize treatment regimens and predict response rates. The statement about acute HCV infection converting to chronic state is accurate, highlighting the need for appropriate management. Immune globulin and vaccines are not available for HCV, and Ribavirin is commonly used for chronic HCV infection. Improving appetite is essential in liver health as adequate nutritional intake supports hepatocyte regeneration. Choices A, C, and D are incorrect as they do not address the specific importance of genotyping in HCV treatment or the significance of appetite improvement in liver function.

4. Which finding is most important for the nurse to communicate to the health care provider about a patient who received a liver transplant 1 week ago?

A. Dry palpebral and oral mucosa
B. Crackles at bilateral lung bases
C. Temperature 100.8?F (38.2?C)
D. No bowel movement for 4 days

Correct answer: C

Rationale: The correct answer is the patient's temperature of 100.8�F (38.2�C). In a patient who received a liver transplant 1 week ago, a fever is a significant finding that should be promptly communicated to the health care provider. Post-transplant patients are at high risk of infections, and fever can often be the initial indicator of an underlying infectious process. The other findings listed in choices A, B, and D are important and should be addressed, but they do not take precedence over a potential infection post-liver transplant. Dry palpebral and oral mucosa may indicate dehydration, crackles at bilateral lung bases may suggest fluid overload or infection, and no bowel movement for 4 days could indicate a bowel obstruction or ileus. However, in the context of a recent liver transplant, an elevated temperature is the most concerning and requires immediate attention to rule out infection.

5. What is the most frequent cause for suicide in adolescents?

A. Progressive failure to adapt
B. Feelings of anger or hostility
C. Reunion wish or fantasy
D. Feelings of alienation or isolation

Correct answer: D

Rationale: Feelings of alienation or isolation are the most frequent cause for suicide in adolescents. Adolescents may experience a gradual isolation leading to a loss of meaningful social contacts, which can be self-imposed or result from an inability to express feelings. During this developmental stage, achieving a sense of identity and peer acceptance is crucial. Choices A, B, and C are incorrect: Progressive failure to adapt, feelings of anger or hostility, and reunion wish or fantasy are not typically identified as the primary cause of suicide in adolescents.
