Exam Cram NCLEX RN Practice Questions

1. Sinusitis is caused by:

A. Bacteria
B. Fungus
C. Virus
D. Any of the above

Correct answer: D

Rationale: Sinusitis can be caused by bacteria, viruses, or fungi. While bacterial infections are the most common cause, viral or fungal infections can also lead to sinusitis. Therefore, the correct answer is 'Any of the above.' Choices A, B, and C are incorrect because they only represent individual causes of sinusitis, whereas choice D encompasses all possible causes.

2. Employee health test results reveal a tuberculosis (TB) skin test of 16-mm induration and a negative chest x-ray for a staff nurse working on the pulmonary unit. The nurse has no symptoms of TB. Which information should the occupational health nurse plan to teach the staff nurse?

A. Standard four-drug therapy for TB
B. Need for annual repeat TB skin testing
C. Use and side effects of isoniazid (INH)
D. Bacille Calmette-Gurin (BCG) vaccine

Correct answer: C

Rationale: The nurse is considered to have a latent TB infection and should be treated with INH daily for 6 to 9 months. The four-drug therapy would be appropriate if the nurse had active TB. TB skin testing is not done for individuals who have already had a positive skin test. BCG vaccine is not used in the United States for TB and would not be helpful for this individual, who already has a TB infection.

3. At a community health fair, the blood pressure of a 62-year-old client is 160/96 mmHg. The client states, "My blood pressure is usually much lower."? The nurse should tell the client to:

A. Go get a blood pressure check within the next 15 minutes
B. Check blood pressure again in two (2) months
C. See the healthcare provider immediately
D. Visit the healthcare provider within one (1) week for a BP check

Correct answer: A

Rationale: The blood pressure reading of 160/96 mmHg is moderately high, indicating hypertension. Given that the client mentions their blood pressure is usually lower, there is concern for acute complications like a stroke. Therefore, an immediate reassessment of the blood pressure within the next 15 minutes is warranted to confirm the reading and take appropriate actions if necessary. Waiting for two months (Choice B) or a week (Choice D) could pose risks of delaying intervention. Seeing the healthcare provider immediately (Choice C) is a good option, but in this case, the urgency is not as high as to require immediate attention at the healthcare provider's office.

4. Your patient has been diagnosed with a left ankle sprain. On the discharge instructions, the physician has prescribed the RICE protocol. This acronym stands for:

A. Rest, Ice, Compression, Elevation
B. Radiology, Ice, Compression, Elevation
C. Rest, Ice, Cast, Elevation
D. Radiology, Ice, Cast, Elevation

Correct answer: A

Rationale: The correct answer is Rest, Ice, Compression, Elevation. This acronym, RICE, is commonly used for the treatment of injuries like an ankle sprain. Rest allows the injured area to heal, Ice helps reduce swelling and pain (20 minutes on each hour while awake), Compression is usually achieved with an elastic bandage to minimize swelling, and Elevation of the foot above the level of the heart assists in reducing swelling and promoting healing. Choices B, C, and D are incorrect because they include irrelevant terms like Radiology and Cast, which are not part of the standard treatment protocol for an ankle sprain.

5. A nurse is caring for a client who is post-op day #1 after a total hip replacement. Although the client was alert with a normal affect in the morning, by lunchtime, the nurse notes the client is confused, has slurred speech, and is having trouble with her balance. Her blood glucose level is 48 mg/dl. What is the next action of the nurse?

A. Contact the physician immediately
B. Administer a bolus of 50 cc of D20W through the IV
C. Administer 10 units of regular insulin
D. Give the client 6 oz. of orange juice

Correct answer: D

Rationale: A client with a blood glucose level of 48 mg/dl is experiencing significant hypoglycemia, as manifested by confusion, balance difficulties, and slurred speech. The nurse should work to correct this situation as rapidly as possible. The first measure that can be performed quickly and will have fast results is to give the client something to eat or drink that contains glucose, such as 6 oz. of orange juice. Administering a bolus of D20W through the IV (Choice B) would be too aggressive and could lead to complications in this scenario. Administering regular insulin (Choice C) would further lower the blood glucose level, worsening the client's symptoms. Contacting the physician (Choice A) is important, but immediate intervention to raise the blood glucose level is crucial to address the client's hypoglycemia.
