NCLEX RN Exam Questions

1. A man is prescribed lithium to treat bipolar disorder. The nurse is most concerned about lithium toxicity when he notices which of these assessment findings?

A. The patient states he had a manic episode a week ago
B. The patient states he has been having diarrhea every day
C. The patient presents as severely depressed
D. The patient has a rash and pruritus on his arms and legs

Correct answer: B

Rationale: The correct answer is when the patient states he has been having diarrhea every day. Persistent diarrhea can lead to dehydration, which can increase the risk of lithium toxicity. The other options, such as a manic episode, severe depression, or rash and pruritus, are not directly associated with an increased risk of lithium toxicity.

2. A systolic blood pressure of 145 mm Hg is classified as:

A. Normotensive
B. Prehypertension
C. Stage I hypertension
D. Stage II hypertension

Correct answer: C

Rationale: A systolic blood pressure of 145 mm Hg falls within the range of 140-159 mm Hg, which is classified as Stage I hypertension. Normotensive individuals have a systolic blood pressure less than 120 mm Hg, making choice A incorrect. Prehypertension is characterized by a systolic blood pressure ranging from 120-139 mm Hg, excluding choice B. Stage II hypertension is diagnosed when the systolic blood pressure is greater than 160 mm Hg, making choice D incorrect. Therefore, the correct classification for a systolic blood pressure of 145 mm Hg is Stage I hypertension.

3. A client is in need of hemodialysis for end-stage renal failure. The physician has inserted an AV fistula. Which of the following nursing interventions is appropriate when caring for this access site?

A. Assess for clotting in fistula tubing
B. Apply a dressing over the fistula site
C. Assess for a bruit or thrill at the site of the fistula
D. Assess circulation proximal to the fistula site

Correct answer: A

Rationale: When caring for an AV fistula used for hemodialysis, it is important to assess for a bruit (a humming sound) or thrill (a vibrating sensation) at the site of the fistula. These indicate proper blood flow through the fistula, ensuring it is patent and suitable for hemodialysis. Assessing for clotting in fistula tubing (Choice A) is not a routine nursing intervention for AV fistulas. Applying a dressing over the fistula site (Choice B) is not necessary as the site needs to be accessible for hemodialysis. Assessing circulation proximal to the fistula site (Choice D) is important but not specific to caring for the access site of an AV fistula.

4. 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.

5. When assessing a patient suspected to have Hepatitis, a nurse notes the patient's eyes are yellow-tinged. Which of the following diagnostic results would further assist in confirming this diagnosis?

A. Decreased serum Bilirubin
B. Elevated serum ALT levels
C. Low RBC and Hemoglobin with increased WBCs
D. Increased Blood Urea Nitrogen level

Correct answer: B

Rationale: Elevated serum ALT levels would further confirm the diagnosis of Hepatitis. ALT is a liver enzyme, and hepatitis is a liver disease. Elevated liver enzymes, such as ALT, often indicate liver damage. Choice A, 'Decreased serum Bilirubin,' is incorrect as elevated bilirubin levels are typically seen in hepatitis due to impaired bilirubin metabolism. Choices C and D are unrelated to confirming a diagnosis of hepatitis as they describe findings not specific to liver function or hepatitis. Low RBC and Hemoglobin with increased WBCs (Choice C) suggest a different condition like anemia or infection, not specific to liver disease. Increased Blood Urea Nitrogen level (Choice D) is more indicative of kidney function rather than liver function, thus not helpful in confirming hepatitis.
