Nclex Exam Cram Practice Questions
1. The nurse is teaching a client about sleep and gives background information on normal sleep patterns. Which of the following substances promotes sleep?
- A. serotonin
- B. cortisol
- C. alcohol
- D. narcotics
Correct answer: A
Rationale: Serotonin is a substance found in the body that promotes sleep. It plays a role in the synthesis of a hypnogenic factor that directly induces sleep. Cortisol is a stress hormone that can disrupt sleep patterns. Alcohol can disrupt REM sleep and negatively impact sleep quality. Narcotics, like alcohol, can interfere with sleep architecture and lead to poor quality sleep. Therefore, the correct answer is serotonin as it is associated with promoting sleep, while the other substances listed can have negative effects on sleep patterns.
2. Which situation is an example of the use of evidence-based practice in the delivery of client care?
- A. Encouraging a client who has had a stroke to consume thickened liquids and soft foods
- B. Picking up a dislodged radiation implant with long-handled forceps and placing it in a lead container to minimize radiation exposure
- C. Pouring 1 to 2 mL of sterile solution that will be used for wound cleansing into a plastic-lined waste receptacle before pouring the solution into a sterile basin
- D. Blowing on a fingerstick site to dry it after cleaning the site with an alcohol swab
Correct answer: C
Rationale: Evidence-based practice is an approach that integrates client preferences, clinical expertise, and the best research evidence to deliver quality care. Pouring sterile solution into a plastic-lined waste receptacle before using it for wound cleansing reflects evidence-based practice by preventing the entrance of harmful bacteria into the wound. Option A is incorrect because encouraging a stroke client to consume thickened liquids and soft foods is appropriate, not thin liquids and foods that pose a choking risk. Option B is incorrect as picking up a radiation implant with long-handled forceps to minimize radiation exposure is a safety measure, not evidence-based practice. Option D is incorrect because blowing on a fingerstick site after cleaning can recontaminate the site, which goes against best practices in infection control.
3. A nurse planning care for her assigned clients understands that which aspect is the purpose of the hospital's standards of care?
- A. Identify methods of treatment.
- B. Provide direction for care based on the client's diagnosis.
- C. Identify new care methods based on current medical research.
- D. Provide direction for the practice of nursing
Correct answer: D
Rationale: The purpose of the hospital's standards of care is to provide a broad direction for the overall practice of nursing that applies to all nursing situations, across specialty areas, and across the country. These standards guide the practice of nursing by outlining the expected level of care and professional performance. While identifying methods of treatment is important, it is usually specific to individual client needs and not the overarching goal of standards of care. Providing direction for care solely based on the client's diagnosis is limited to a particular patient's treatment plan and does not encompass the broader scope of nursing practice. Identifying new care methods based on current medical research is essential for advancing healthcare practices but is not the primary purpose of the hospital's standards of care.
4. When a 17-year-old client arrives at the clinic suspecting a sexually transmitted infection, what information does the nurse provide concerning informed consent?
- A. She will need to sign an informed consent form.
- B. Her mother or father will need to be contacted for permission to treat her.
- C. A consent form is not needed if the problem is a sexually transmitted infection.
- D. Anyone over the age of 18 years may sign a consent form for her treatment.
Correct answer: A
Rationale: Informed consent is a person's agreement to allow something, such as a treatment, to be performed. A consent form is required even if the problem is a sexually transmitted infection. If the client is a minor, the minor may sign the informed consent form in specific situations, including seeking treatment for a sexually transmitted infection. In this case, the 17-year-old client is seeking examination and treatment for a sexually transmitted infection, so she will need to sign the informed consent form. Contacting her parents for permission is not required in this situation. Choice C is incorrect because a consent form is necessary regardless of the medical issue. Choice D is incorrect because the individual's age is not the determining factor; rather, it is the nature of the medical service being sought that dictates the need for informed consent.
5. A client is diagnosed with HIV. Which of the following antiviral drug classes are used in the treatment of HIV/AIDS?
- A. nucleoside reverse transcriptase inhibitors
- B. protease inhibitors
- C. HIV fusion inhibitors
- D. all of the above
Correct answer: D
Rationale: All of the provided choices are antiviral drug classes used in the treatment of HIV/AIDS. Nucleoside reverse transcriptase inhibitors, such as tenofovir and emtricitabine, work by interfering with the virus's ability to replicate. Protease inhibitors, like atazanavir and darunavir, block an enzyme that HIV needs to make copies of itself. HIV fusion inhibitors, for instance, enfuvirtide, prevent HIV from entering human cells. Therefore, 'all of the above' is the correct answer as all the listed drug classes are commonly used in managing HIV infections. Choices A, B, and C are all essential components of antiretroviral therapy for HIV, targeting different stages of the virus's life cycle. The combination of drugs from these classes is often recommended to effectively control HIV replication and reduce viral load.
