NCLEX RN Predictor Exam
1. 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?
- A. Do not perform the procedure. Notify the physician of the reason why.
- B. Perform the procedure but pay close attention for signs of potential syncope.
- C. Allow the patient to reschedule for a time when he isn't as anxious.
- D. Have the physician draw the blood.
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.
2. When printing out an EKG, a nurse notices that the QRS complexes are extremely small. What should be the next step?
- A. Alert the physician immediately as this is a sign of impending cardiac arrest.
- B. Check to see that all leads are attached and rerun the EKG.
- C. Increase the sensitivity control to 20 mm deflection.
- D. Decrease the run speed to 50.
Correct answer: C
Rationale: Increasing the sensitivity control to 20 mm deflection will double the sensitivity, allowing for better observation of the small QRS complexes. This step is crucial in obtaining a clearer EKG reading. Choice A is incorrect because small QRS complexes do not necessarily indicate impending cardiac arrest; it's more likely a technical issue. Choice B is not the first step to take when small QRS complexes are observed; it's important to adjust the settings first. Choice D is incorrect because decreasing the run speed to 50 is not the appropriate action for this situation; adjusting the sensitivity control is more relevant to improve the visualization of the complexes.
3. A nurse is preparing to insert a small-bore nasogastric feeding tube for a client's enteral feedings. In which method does the nurse measure the correct length of the tube?
- A. From the tip of the nose to the xiphoid process
- B. From the tip of the nose to the earlobe to the xiphoid process
- C. From the earlobe to the xiphoid process
- D. From the tip of the nose to the earlobe to the umbilicus
Correct answer: B
Rationale: When preparing to insert a nasogastric tube, the nurse must measure the correct length to ensure that the end of the tube will be in the correct position in the stomach. The accurate method to measure the length is from the tip of the nose to the earlobe to the xiphoid process. This length ensures that the end of the tube reaches the stomach, avoiding placement in the small intestine or esophagus. Choice A is incorrect as it does not include the earlobe, which is essential for accurate measurement. Choice C is incorrect because measuring from the earlobe alone does not provide the correct length for positioning in the stomach. Choice D is incorrect as it includes the umbilicus, which is not the appropriate landmark for measuring the length of a nasogastric tube intended for stomach placement.
4. A patient is having difficulty understanding how to properly run her glucose meter. Which of the following teaching methods would best help the patient understand how to use her instrument correctly?
- A. Give the patient an instruction booklet and encourage her to call the office if she has questions.
- B. Tell the patient to ask a healthcare provider to demonstrate how to use the instrument.
- C. Have the patient watch a video demonstrating the use of the instrument.
- D. Demonstrate the proper use of the instrument and then have the patient perform the process while still in the office.
Correct answer: D
Rationale: By using a demonstration and performance method of patient education, the patient is offered a chance to perform a task and have learning assessed while still in the office. This ensures that any questions that the patient has can be answered immediately, and any performance issues observed by the medical assistant can also be corrected promptly. Choice A is not as effective as providing a demonstration in person, as it may not address the patient's specific learning needs or allow for immediate feedback. Choice B suggests asking a healthcare provider to demonstrate, which is similar to the correct answer but may not always be readily available in the office. Choice C, watching a video, lacks the interactive component and immediate feedback that a live demonstration provides, making it less effective in this scenario.
5. Which gland of the endocrine system secretes a hormone that assists with the sleep/wake cycle?
- A. Pituitary
- B. Pineal
- C. Pancreas
- D. Hypothalamus
Correct answer: B
Rationale: The correct answer is the Pineal gland. The Pineal gland, located in the brain, secretes melatonin, which plays a crucial role in regulating the sleep/wake cycle in response to exposure to light. The Pituitary gland (Choice A) secretes various hormones but not specifically related to the sleep/wake cycle. The Pancreas (Choice C) secretes insulin and digestive enzymes, not hormones related to the sleep/wake cycle. The Hypothalamus (Choice D) is involved in regulating many bodily functions, including hormone secretion, but it does not directly secrete the hormone that regulates the sleep/wake cycle.
