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. A physician has written an order for '2.0 mg MS q 2-4 hr prn pain.' What is the nurse's appropriate response to this order?
- A. Give 2 mg of morphine sulfate to the client
- B. Give 20 mg of morphine sulfate to the client
- C. Contact the pharmacy to clarify the order
- D. Contact the physician to rewrite the order
Correct answer: D
Rationale: The physician's order contains several errors that could lead to potential harm to the client if not addressed. The use of '2.0' involves a trailing decimal point, which may lead to confusion regarding the intended dose of the drug. Additionally, the abbreviation 'MS' is considered a Do Not Use abbreviation by the Joint Commission, as it could refer to morphine sulfate or magnesium sulfate, leading to medication errors. While the order indicates the drug should be used for pain, the nurse should contact the physician to clarify the exact dose and specific drug to be administered, ensuring safe and accurate medication administration. Therefore, the correct response is to contact the physician to rewrite the order.
3. A client with a new prescription for lithium carbonate for bipolar disorder is being educated by a nurse on early indications of toxicity. The nurse should include which of the following manifestations in the teachings?
- A. Constipation
- B. Polyuria
- C. Rash
- D. Tinnitus
Correct answer: B
Rationale: Polyuria is a crucial early indication of lithium toxicity. It results from the drug's effect on the kidneys, leading to increased urine output. This is a significant symptom to monitor as it can indicate potential toxicity. Constipation, rash, and tinnitus are not typically associated with early indications of lithium toxicity. Constipation is more commonly seen as a side effect of some medications, while rash and tinnitus are not specific indicators of lithium toxicity.
4. A client is receiving education on cholesterol. Which of the following statements from the client indicates the need for further teaching?
- A. I would like my HDL levels to be over 50.
- B. It is better for me to have high HDL levels and low LDL levels.
- C. It is better for me to have high LDL levels and low HDL levels.
- D. My goal is to get my total cholesterol below 200.
Correct answer: C
Rationale: The correct answer is, 'It is better for me to have high LDL levels and low HDL levels.' This statement indicates a need for further teaching because high LDL levels contribute to atherosclerosis, while high HDL levels can protect against heart disease. The client should understand the importance of lowering LDL levels and increasing HDL levels to maintain good heart health. Choice A is correct as desiring HDL levels over 50 is a positive goal. Choice B is correct as it reflects the ideal scenario of high HDL and low LDL levels. Choice D is correct as a total cholesterol below 200 is a common goal for heart health. Therefore, Choice C is incorrect as it suggests an opposite and unhealthy relationship between LDL and HDL levels.
5. A nurse is assessing a client's pulse oximetry on the surgical unit. As part of routine interventions, the nurse turns off the exam light over the client's bed. Which of the following best describes the rationale for this intervention?
- A. External light sources may cause falsely high oximetry values
- B. A bright light in the client's face may cause a low pulse oximetry
- C. External light sources may cause falsely low oximetry values
- D. The client needs a dark and quiet room to recover and maintain proper oxygenation
Correct answer: A
Rationale: When assessing a client's pulse oximetry values, the nurse should turn off any extra environmental lights that are unnecessary, including exam lights or over-bed lights. External light sources may cause falsely high oximetry values when the extra light interferes with the sensor of the oximeter, leading to inaccurate readings. Choice B is incorrect because a bright light in the client's face would not directly affect the pulse oximetry values. Choice C is incorrect as external light sources typically cause falsely high, not low, oximetry values. Choice D is incorrect as the primary reason for turning off the light is to prevent falsely high readings, not solely for the client's comfort.
