NCLEX RN Exam Review Answers
1. A client is diagnosed with schizophrenia. A physician orders haloperidol (Haldol) 50 mg bid, benztropine (Cogentin) 1 mg prn, and zolpidem (Ambien) 10 mg HS. Which client behavior would warrant the nurse to administer benztropine?
- A. Tactile hallucinations
- B. Tardive dyskinesia
- C. Restlessness and muscle rigidity
- D. Reports of hearing disturbing voices
Correct answer: C
Rationale: Benztropine (Cogentin) is an anticholinergic medication used to treat extrapyramidal symptoms, such as restlessness and muscle rigidity, which are common side effects of antipsychotic medications like haloperidol. Tactile hallucinations and reports of hearing disturbing voices are symptoms of schizophrenia that would typically be addressed by the antipsychotic medication (haloperidol) itself. Tardive dyskinesia, a potential side effect of long-term antipsychotic use, would require discontinuation of the antipsychotic medication rather than administration of benztropine.
2. What ethical principle has led to the need for informed consent?
- A. Autonomy
- B. Justice
- C. Fidelity
- D. Beneficence
Correct answer: A
Rationale: Autonomy is the ethical principle that emphasizes an individual's right to make their own decisions if they are mentally competent. Informed consent is a direct result of this principle, as it ensures that patients are fully informed before agreeing to any medical intervention. Autonomy is crucial in healthcare as it respects patients' rights and promotes self-determination. Justice, fidelity, and beneficence are important ethical principles in healthcare, but they do not directly lead to the need for informed consent. Justice focuses on fairness and equal treatment, fidelity on trustworthiness and loyalty, and beneficence on doing good for the patient's benefit.
3. A client is preparing to give a stool sample for occult blood. All of the following information is part of teaching for this client EXCEPT:
- A. Avoid eating red meat for 3 days before the test
- B. Collect the stool sample from the toilet after having a bowel movement
- C. The stool does not need to be kept in a container with preservative
- D. A small part of the stool from two areas will be tested using a smear
Correct answer: B
Rationale: When preparing to give a stool sample for occult blood testing, clients need specific instructions to ensure accurate results. It is crucial to educate clients to avoid eating red meat for at least 3 days before the test, as the blood in the meat can interfere with the test results. Clients should be informed that the stool does not need to be kept in a container with preservative as it is not required for this type of testing. Additionally, clients should be aware that a small part of the stool from two areas will be tested using a smear. However, collecting the stool sample from the toilet after having a bowel movement is not recommended as it may introduce contaminants and affect the accuracy of the test. Therefore, this information is not part of the correct teaching for the client preparing to give a stool sample for occult blood.
4. An infant is brought to the clinic by his mother, who has noticed that he holds his head in an unusual position and always faces to one side. Which of the following is the most likely explanation?
- A. Torticollis, with shortening of the sternocleidomastoid muscle
- B. Craniosynostosis, with premature closure of the cranial sutures
- C. Plagiocephaly, with flattening of one side of the head
- D. Hydrocephalus, with increased head size
Correct answer: A
Rationale: The correct answer is torticollis, characterized by the shortening of the sternocleidomastoid muscle, limiting the range of motion of the neck and causing the chin to point to the opposing side. Craniosynostosis is the premature closure of cranial sutures, leading to an abnormal head shape but not necessarily affecting head position. Plagiocephaly is flattening of one side of the head due to external forces or positioning, not muscle shortening. Hydrocephalus presents with an increased head size due to the accumulation of cerebrospinal fluid, not with a fixed head position.
5. A healthcare professional is preparing to draw a blood specimen from an adult client's central line. All of the following actions for this procedure are correct EXCEPT:
- A. Disconnect the current infusion
- B. Clean the cap with alcohol and attach a 5 cc syringe
- C. Draw 5 cc of a blood sample to discard
- D. Flush with saline after the sample
Correct answer: B
Rationale: When drawing a blood specimen from a central line, the healthcare professional should disconnect any infusions that are currently running and that could contaminate the specimen. It is important to use a minimum size of a 10 cc syringe when using a central line to avoid placing too much pressure on the catheter. Cleaning the cap with alcohol and attaching a 5 cc syringe is not appropriate as a larger syringe size should be used for this procedure. Drawing 5 cc of a blood sample to discard and flushing with saline after the sample are correct steps in the process of drawing a blood specimen from a central line.
