Nclex Exam Cram Practice Questions

1. Which of the following indicates a hazard for a client on oxygen therapy?

A. A 'No Smoking' sign is on the door.
B. The client is wearing a synthetic gown.
C. Electrical equipment is grounded.
D. Matches are removed.

Correct answer: B

Rationale: The correct answer is that the client is wearing a synthetic gown. A synthetic gown might generate sparks of static electricity, which can be a fire hazard, especially in the presence of oxygen. Clients on oxygen therapy should wear cotton gowns to minimize the risk of fire. The other options are not hazards for a client on oxygen therapy: having a 'No Smoking' sign on the door promotes safety by preventing smoking, ensuring electrical equipment is grounded reduces the risk of electrical hazards, and removing matches decreases the risk of fire hazards.

2. How does cancer affect pain tolerance in elderly clients?

A. Remain constant.
B. Decrease.
C. Increase.
D. Cancer has no impact on pain tolerance in elderly clients.

Correct answer: B

Rationale: Pain tolerance in elderly clients with cancer is likely to decrease due to factors such as diminished adaptative capacity, increased physical discomfort, and the psychological impact of the disease. Cancer is known to cause various physical and emotional stressors that can lower the pain threshold, leading to a decrease in pain tolerance. Choices A, C, and D are incorrect because cancer and its associated effects typically result in a decrease in pain tolerance rather than remaining constant, increasing, or having no impact.

3. A 51-year-old client with amyotrophic lateral sclerosis (Lou Gehrig disease) is admitted to the hospital because his condition is deteriorating. The client tells the nurse that he wants a do-not-resuscitate (DNR) order. The nurse should provide the client with which information?

A. Oral consent is not sufficient, and the client's request will be honored by all healthcare providers.
B. Consent must be obtained from the family.
C. The DNR request should be discussed with the healthcare provider, who will write the order.
D. The healthcare provider makes the final decision about a DNR request.

Correct answer: C

Rationale: When a client requests a DNR order, the nurse should contact the healthcare provider so that the provider may discuss the request with the client. A DNR order should be written, not verbal, following agency and state guidelines. Therefore, the correct answer is that the DNR request should be discussed with the healthcare provider, who will write the order. Option A is incorrect as oral consent is not sufficient for a DNR order. Option B is incorrect because the client, not the family, has the authority to request a DNR order. Option D is incorrect because the healthcare provider discusses the request with the client but does not make the final decision.

4. The healthcare provider sustains a needle puncture that requires HIV prophylaxis. Which of the following medication regimens should be used?

A. an antibiotic such as Metronidazole and a protease inhibitor (Saquinavir)
B. two non-nucleoside reverse transcriptase inhibitors
C. one protease inhibitor such as Nelfinavir
D. two protease inhibitors

Correct answer: B

Rationale: In the scenario of a needle puncture requiring HIV prophylaxis, the CDC recommends initiating treatment with two non-nucleoside reverse transcriptase inhibitors, unless there is drug resistance. This regimen is preferred over other options such as a single protease inhibitor or two protease inhibitors due to its effectiveness and safety profile in this specific context. Non-nucleoside reverse transcriptase inhibitors are commonly used in post-exposure prophylaxis due to their activity against HIV and lower risk of resistance development compared to other antiretroviral drug classes.

5. A child comes to the clinic with a skin rash. The maculopapular lesions are distributed around the mouth and have honey-colored drainage. The caregiver states that the rash is getting worse and seems to spread with the child's scratching. Which of the following advisory comments should be given?

A. The history and presentation might indicate chickenpox, a highly contagious disease.
B. The lesions might indicate a noncontagious infection that does not require isolation.
C. The history and presentation might indicate an infectious illness called impetigo.
D. The lesions are not contagious unless others have open wounds or lesions themselves.

Correct answer: C

Rationale: The scenario describes classic impetigo, which typically presents with maculopapular lesions around the mouth with honey-colored drainage, worsening with scratching. It is important to advise the caregiver that the history and presentation are indicative of impetigo, an infectious skin condition caused by bacteria. Treatment usually involves antibiotic therapy. Choice A is incorrect because chickenpox typically presents with a vesicular rash following a history of high fever. Choice B is incorrect as impetigo is contagious and requires precautions to prevent the spread of infection. Choice D is incorrect as impetigo is contagious irrespective of open wounds or lesions in others.
