Nclex PN Questions and Answers

1. Which of the following is true of advanced directives?

A. They should be appropriately documented in the client's chart.
B. They are only applicable if the client has a terminal illness.
C. They are required if the client is unconscious.
D. They are non-legal requests.

Correct answer: A

Rationale: The correct answer is that advanced directives should be appropriately documented in the client's chart. Advanced directives are legal requests regarding a client's healthcare that come into effect under specific circumstances, regardless of the severity of their illness or level of consciousness. Choice B is incorrect because advanced directives can cover various healthcare decisions, not just terminal illnesses. Choice C is incorrect as advanced directives can be established and documented while the client is conscious, not only if they are unconscious. Choice D is incorrect because advanced directives are indeed legal requests, not non-legal requests.

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. When a client needs oxygen therapy, what is the highest flow rate that oxygen can be delivered via nasal cannula?

A. 2 liters/minute
B. 4 liters/minute
C. 6 liters/minute
D. 8 liters/minute

Correct answer: C

Rationale: The correct answer is 6 liters/minute. When a client requires oxygen therapy, the maximum flow rate that oxygen can be delivered via nasal cannula is 6 liters/minute. Nasal cannula can effectively deliver oxygen up to 6 liters/minute. Flow rates exceeding 6 liters/minute may lead to drying of the nasal passages and discomfort for the client. Higher flow rates, like 8 liters/minute, should be administered using a mask to ensure sufficient oxygenation. Options A, B, and D are incorrect as they indicate flow rates that surpass the recommended maximum for nasal cannula delivery.

4. The nurse is teaching a client about erythema infectiosum. Which of the following factors is not correct?

A. There is no rash.
B. The disorder is uncommon in adults.
C. There is no fever.
D. There is sometimes a 'slapped face' appearance.

Correct answer: B

Rationale: The correct answer is that the disorder is uncommon in adults. Erythema infectiosum, also known as Fifth's disease, commonly affects children and is characterized by a 'slapped face' appearance. It is associated with a rash and sometimes a low-grade fever. Therefore, the statement 'The disorder is uncommon in adults' is not correct, making it the correct answer. The other statements about the presence of a rash, 'slapped face' appearance, and the possibility of a fever are accurate in the context of erythema infectiosum.

5. People living in poverty are most likely to obtain health care from:

A. their primary care physician (family doctor)
B. a neighborhood clinic
C. specialists
D. Emergency Departments or urgent care centers

Correct answer: D

Rationale: People living in poverty often face barriers to accessing regular healthcare services, leading them to seek care in Emergency Departments or urgent care centers. These facilities are more accessible and do not require appointments or insurance, making them a common choice for individuals with limited resources. Neighborhood clinics, while a good option, may not always be available or affordable for those in poverty. Specialists provide specialized care but usually require a referral from a primary care provider, which individuals in poverty may not have consistent access to. Therefore, Emergency Departments or urgent care centers are the most likely sources of healthcare for people living in poverty.
