Nclex PN Questions and Answers

1. Which of the following is not an advanced directive?

A. informed consent
B. living will
C. durable power of attorney for health care
D. health care proxy

Correct answer: informed consent

Rationale: Informed consent is the process of obtaining permission from a patient before conducting a healthcare intervention. It is not considered an advanced directive. A living will is a legal document that outlines a person's preferences for medical treatment if they are unable to communicate. A durable power of attorney for health care designates a person to make medical decisions on behalf of the patient. A health care proxy, which is another term for a durable power of attorney for health care, also involves appointing someone to make healthcare decisions for an individual if they become unable to do so. Therefore, the correct answer is 'informed consent,' as it is not an advanced directive but rather a different aspect of patient care.

2. How should an infant be secured in a car?

A. To hold the infant while sitting in the middle of the back seat of the car
B. To place the infant in the front seat in a rear-facing infant safety seat if the car has passenger-side air bags
C. To place the infant in a booster seat in the front seat with the shoulder and lap belts secured around the infant
D. To secure the infant in the middle of the back seat in a rear-facing infant safety seat

Correct answer: To secure the infant in the middle of the back seat in a rear-facing infant safety seat

Rationale: The recommended way to secure an infant in a car is to place them in the middle of the back seat in a rear-facing infant safety seat. Option A is incorrect because infants should never be held while in a moving vehicle due to safety concerns. Option B is incorrect because placing an infant in the front seat with a rear-facing safety seat can be risky if the car has passenger-side airbags. Option C is incorrect as booster seats are not suitable for infants. Therefore, the correct choice is to secure the infant in the middle of the back seat in a rear-facing infant safety seat.

3. Which of the following lab values is elevated first after a client has a myocardial infarction?

A. LDH
B. troponin
C. CPK
D. SGOT

Correct answer: troponin

Rationale: The correct answer is troponin. Troponin levels are the most specific and sensitive markers for myocardial infarction, and they begin to rise within a few hours after the event. CPK, SGOT, and LDH are also enzymes that can indicate myocardial damage, but troponin is the earliest and most specific indicator. CPK typically rises 4-8 hours after an infarction, followed by SGOT (AST) at 8-12 hours, and LDH at 12-24 hours post-infarction.

4. To assess a client's ankle ROM, which ROM exercises should the nurse have them perform?

A. flexion, extension, hyperextension
B. flexion, extension, abduction, adduction
C. external rotation, internal rotation
D. extension, flexion, inversion, eversion

Correct answer: extension, flexion, inversion, eversion

Rationale: The correct answer is extension, flexion, inversion, and eversion. These exercises help assess the full range of motion of the ankles. Flexion and extension evaluate the bending and straightening movements of the ankle joint, respectively. Inversion and eversion assess the inward and outward movements of the foot at the ankle joint. Hyperextension, abduction, and adduction are not specific movements of the ankle joint, making choices A and B incorrect. External and internal rotation are movements more related to joints like the hip or shoulder, not the ankle, making choice C incorrect.

5. In an emergency situation where a client is unconscious and requires immediate surgery, what action is necessary with regard to informed consent?

A. The healthcare team will proceed with the surgery as consent is not needed in emergencies.
B. The healthcare team will wait until the client's family can be contacted for consent.
C. The healthcare team will contact the hospital clergy to provide informed consent.
D. The healthcare team will obtain consent from the client's legal guardian before proceeding.

Correct answer: The healthcare team will proceed with the surgery as consent is not needed in emergencies.

Rationale: In emergency situations where obtaining consent is not possible due to the client's condition, healthcare providers are allowed to perform life-saving procedures without informed consent. It is assumed that the client would want to receive necessary treatment to save their life. Therefore, the correct action is for the healthcare team to proceed with the surgery as consent is not needed. Waiting to contact the client's family for consent can delay life-saving treatment, risking the client's life. Contacting the hospital clergy for consent is unnecessary and can cause further delays. Obtaining consent from the client's legal guardian is not feasible in this critical situation and may lead to a delay in providing essential care.
