NCLEX RN Exam Review Answers
1. Why should a 30-year-old Caucasian woman who works the night shift take Vitamin D supplements?
- A. It's a standard part of the overall nutritional treatment for the prevention of osteomalacia.
- B. It helps your intestines absorb calcium, which is important for bone formation.
- C. It stimulates skin cells to produce calcium, which is then released into the bloodstream to be used for bone formation.
- D. Vitamin D supplements should not be taken by someone of your age.
Correct answer: B
Rationale: The correct answer is B: 'It helps your intestines absorb calcium, which is important for bone formation.' Vitamin D plays a crucial role in aiding the absorption of calcium from the intestines into the bloodstream, which is essential for bone health and formation. Choice A is incorrect because it does not specifically address the role of Vitamin D in calcium absorption. Choice C is incorrect as Vitamin D does not stimulate skin cells to produce calcium; rather, it helps regulate calcium levels in the body. Choice D is incorrect as age alone is not a contraindication for Vitamin D supplementation; the need for supplementation is based on individual health status and risk factors.
2. An infant has just returned to the nursing unit after surgical repair of a cleft lip on the right side. The nurse should place the infant in which best position at this time?
- A. Prone position
- B. On the stomach
- C. Left lateral position
- D. Right lateral position
Correct answer: C
Rationale: After surgical repair of a cleft lip on the right side, the nurse should position the infant carefully to ensure comfort and prevent complications. Placing the infant in the prone position or on the stomach is not recommended as it may cause rubbing of the surgical site against the mattress. The optimal position for the infant is the left lateral position, away from the surgical repair site, to minimize the risk of trauma. Placing the infant on the right lateral position would be contraindicated as it is on the side of the repair. Additionally, positioning the infant upright on the back can help prevent airway obstruction by secretions, blood, or the tongue. Therefore, the correct choice is to place the infant in the left lateral position to promote safety and comfort post cleft lip surgery.
3. The client is being prepared for insertion of a pulmonary artery catheter (Swan-Ganz catheter). What information does the client need to know about the purpose of this catheter insertion?
- A. Stroke volume
- B. Cardiac output
- C. Venous pressure
- D. Left ventricular functioning
Correct answer: D
Rationale: The correct answer is D: Left ventricular functioning. The purpose of inserting a pulmonary artery catheter is to obtain information about left ventricular functioning when the catheter balloon is inflated. Choices A, B, and C are incorrect because while a pulmonary artery catheter can provide information on stroke volume, cardiac output, and venous pressure, its primary purpose is to assess left ventricular function.
4. A 36-year-old male patient in the outpatient clinic is diagnosed with acute hepatitis C (HCV) infection. Which action by the nurse is appropriate?
- A. Schedule the patient for HCV genotype testing.
- B. Administer the HCV vaccine and immune globulin.
- C. Teach the patient about ribavirin (Rebetol) treatment.
- D. Explain that the infection will resolve over a few months.
Correct answer: A
Rationale: The correct action by the nurse is to schedule the patient for HCV genotype testing. Genotyping of HCV is crucial in determining the appropriate treatment regimen and guiding therapy decisions. Most patients with acute HCV infection progress to the chronic stage, so it is incorrect to inform the patient that the infection will resolve in a few months. There is no vaccine or immune globulin available for HCV, and ribavirin (Rebetol) is typically used for chronic HCV infection. Therefore, the nurse should prioritize genotyping to assist in treatment planning.
5. A patient is admitted to the same-day surgery unit for a liver biopsy. Which of the following laboratory tests assesses coagulation? Select one that doesn't apply.
- A. Partial thromboplastin time
- B. Prothrombin time
- C. Platelet count
- D. Hemoglobin
Correct answer: D
Rationale: The correct answer is 'Hemoglobin.' Hemoglobin levels are not indicative of coagulation status but are important for assessing oxygen-carrying capacity. Choices A, B, and C are all laboratory tests that assess coagulation. Partial thromboplastin time (PTT) and prothrombin time (PT) evaluate different aspects of the coagulation cascade, while platelet count is essential for assessing primary hemostasis. Therefore, in the context of evaluating coagulation, hemoglobin is not the appropriate choice.
