NCLEX RN Predictor Exam Questions
Extract:
Question 1 of 5
Digestion, elimination, and ___________ are the three functions of the digestive system.
Correct Answer: C
Rationale: The correct answer is 'absorption.' The three main functions of the digestive system are digestion, absorption, and elimination. Absorption refers to the process of absorbing nutrients and other substances from the digested food into the bloodstream.
Choices A, B, and D are incorrect: Constriction is not a primary function of the digestive system, relaxation is not a distinct function in this context, and peristalsis is a muscular movement that aids in digestion but is not one of the three main functions of the digestive system.
Question 2 of 5
Which desired outcome written by the nurse is correctly written and measurable?
Correct Answer: B
Rationale: An outcome statement must describe the observable client behavior that should occur in response to the nursing interventions. It consists of a subject, action verb, conditions under which the behavior is to be performed, and the level at which the client will perform the desired behavior. Option B is correctly written and measurable as it includes all the required elements: subject (client), action verb (lose), conditions (within the next 2 weeks), and the level at which the behavior should occur (4 lbs.). Option A lacks the conditions and a specific level, making it not measurable. Option C is a nursing intervention rather than a client goal. Option D does not provide a specific level at which the client should perform the desired behavior, making it not measurable as well.
Question 3 of 5
Which vacutainer tubes should be used when a requisition calls for blood to be drawn for an H&H and glucose test?
Correct Answer: D
Rationale: The correct answer is 'One green, one red.' An H&H test involves hemoglobin and hematocrit, which are components of a complete blood count and are typically drawn in a lavender tube. On the other hand, blood for glucose testing is collected in grey tubes.
Therefore, when drawing blood for both an H&H and glucose test, one green tube for glucose and one red tube for H&H should be used. The other choices are incorrect because light blue tubes are used for coagulation studies, lavender tubes are for complete blood counts, and green tubes are for chemistry tests like glucose, while grey tubes are specifically for glucose testing.
Question 4 of 5
A patient has come to the office for a blood draw. The patient starts to sweat and is very anxious. Which of the following would be the BEST way to proceed?
Correct Answer: B
Rationale: In the scenario where a patient is sweating and anxious, it is important to assess for signs of potential syncope (fainting) while proceeding with the blood draw. If the patient does not exhibit signs of fainting, the phlebotomy procedure can be performed safely. Postponing the procedure may not address the patient's anxiety and inconvenience them. Having the physician draw the blood is not necessary if the phlebotomist can handle the situation effectively.
Question 5 of 5
In addition to standard precautions, the nurse caring for a patient with rubella would plan to implement what type of precautions?
Correct Answer: A
Rationale: Rubella is an illness transmitted by large-particle droplets, so the nurse should implement droplet precautions in addition to standard precautions. Airborne precautions are used for diseases spread through small particles in the air, such as tuberculosis, varicella, and rubeola. Contact precautions are utilized for diseases transmitted by direct contact with the patient or their environment. Universal precautions and body substance isolations are part of the CDC's standard precautions recommendations, but do not specifically address the transmission route of rubella.
