2024 PN NCLEX Questions

1. What effect can medication bound to protein have?

Correct answer: C

Rationale: Medication bound to protein leads to less availability to produce desired medicinal effects because only unbound drugs can interact with active receptor sites. If a drug is bound to protein, it cannot bind with a receptor site, reducing its effectiveness. Choice A is incorrect because binding to protein reduces drug availability. Choice B is incorrect because distribution to receptor sites is ineffective if the drug is bound to protein. Choice D is incorrect because metabolism does not occur until the drug is removed from the protein molecule by the liver, allowing the protein to return to circulation.

2. A nurse assisting with data collection plans to assess tactile (vocal) fremitus. The nurse performs this by using which technique?

Correct answer: D

Rationale: To assess tactile (vocal) fremitus, the nurse palpates the thorax and compares vibrations from side to side as the client repeats the word 'ninety-nine.' This technique helps in evaluating the intensity and symmetry of vibrations felt. Palpating for symmetric chest expansion involves assessing the expansion of the chest during breathing by placing hands on the anterolateral wall. Auscultating the breath sounds over the trachea and larynx is done to assess bronchial breath sounds, while auscultating over the peripheral lung fields is used to assess vesicular breath sounds.

3. A nurse is preparing to assess the fetal heart rate (FHR) of a client who is 14 weeks pregnant. Which piece of equipment does the nurse use to assess the FHR?

Correct answer: B

Rationale: To assess the fetal heart rate of a client who is 14 weeks pregnant, the nurse should use a Doppler transducer. Fetal heart sounds can be heard with a fetoscope by 20 weeks of gestation. The Doppler transducer amplifies fetal heart sounds so that they are audible by 10 to 12 weeks of gestation, making it the most appropriate choice for this scenario. Fetal heart sounds cannot be heard with a stethoscope. Pulse oximetry is not used to auscultate fetal heart sounds, so it is an incorrect choice in this context.

4. All of the following factors, when identified in the history of a family, are correlated with poverty except:

Correct answer: D

Rationale: The correct answer is 'low incidence of dental problems.' Dental problems are prevalent in families living in poverty due to the lack of preventive care and access to dental services. High infant mortality rate is closely correlated with poverty as it reflects various social determinants of health. Families in poverty may resort to frequent use of Emergency Departments due to limited access to primary care. Consulting with folk healers is also common among families in poverty as they might seek alternative and more accessible healthcare options. However, a low incidence of dental problems is less likely in families experiencing poverty.

5. A nurse assisting with data collection is preparing to assess the optic nerve. The nurse performs this examination by using which technique?

Correct answer: A

Rationale: The correct technique to assess the optic nerve is by testing visual acuity and visual fields through confrontation. Visual acuity involves assessing the clarity of vision, which directly correlates with the function of the optic nerve. Inspecting the eyelids for ptosis is unrelated to optic nerve assessment. Assessing pupil constriction is more related to the assessment of cranial nerves controlling eye movements, particularly the oculomotor nerve. Assessing ocular movements is related to testing the abducens, oculomotor, and trochlear nerves, not specifically the optic nerve.
