NCLEX RN Predictor Exam
1. A resident brings several electronic devices to a nursing home. One of the devices has a two-pronged plug. What rationale should the nurse provide when explaining why an electrical device must have a three-pronged plug?
- A. Controls stray electrical currents.
- B. Promotes efficient use of electricity.
- C. Shuts off the appliance if there is an electrical surge.
- D. Divides the electricity among the appliances in the room.
Correct answer: A
Rationale: A three-pronged plug functions as a ground to dissipate stray electrical currents. This helps prevent electrical shocks and ensures the safety of the user. Choice B is incorrect because the number of prongs on a plug does not impact the efficient use of electricity. Choice C is incorrect because a three-pronged plug does not shut off the appliance during an electrical surge; that role is typically fulfilled by surge protectors. Choice D is incorrect as a three-pronged plug does not divide electricity among appliances in a room; it primarily serves as a safety measure to handle excess electrical currents.
2. During an examination, the nurse notices that a female patient has a round "moon"? face, central trunk obesity, and a cervical hump. Her skin is fragile with bruises. The nurse determines that the patient likely has which condition?
- A. Gigantism
- B. Acromegaly
- C. Cushing syndrome
- D. Marfan syndrome
Correct answer: C
Rationale: Cushing syndrome is characterized by weight gain and edema with central trunk and cervical obesity (buffalo hump) and a round, plethoric face (moon face). Excessive catabolism in Cushing syndrome causes muscle wasting, weakness, thin arms and legs, reduced height, and thin, fragile skin with purple abdominal striae, bruising, and acne. Gigantism is characterized by increased height and weight and delayed sexual development, which are not present in the patient. Acromegaly results from excessive growth hormone secretion in adulthood, leading to bone overgrowth in specific areas like the face, head, hands, and feet. Marfan syndrome is an inherited connective tissue disorder characterized by a tall, thin stature and distinct features not seen in this patient. The combination of signs described in the question aligns with the clinical presentation of Cushing syndrome.
3. Which of the following actions can help prevent a fire in the area where a healthcare professional works?
- A. Using an adaptor when plugging in client equipment
- B. Marking equipment that is not working properly and using it carefully until it can be inspected by maintenance
- C. Notifying visitors or posting signs that indicate oxygen is in use in certain areas
- D. Keeping extra equipment stored in one area with other supplies and materials
Correct answer: C
Rationale: The correct action to help prevent a fire in a healthcare setting is to notify visitors or post signs indicating that oxygen is in use in certain areas. Oxygen is a combustible material, and awareness of its presence is crucial to prevent fire hazards. By informing all individuals in the facility about the use of oxygen through clear signs or notifications, the risk of improper use and potential fire accidents can be minimized. Choice A is incorrect because using an adaptor when plugging in client equipment is not directly related to fire prevention. Choice B is also incorrect as marking faulty equipment and using it until inspection does not directly address fire prevention. Choice D is not a recommended action for fire prevention; storing extra equipment with supplies does not address the specific fire risk associated with oxygen use.
4. An older adult patient brought to the emergency department by a family member is wandering outside, saying, "I can't find my way home."? The patient is confused and unable to answer questions. What is the nurse's best action?
- A. Document the patient's mental status and obtain other assessment data from the family member.
- B. Record the patient's answers to questions on the nursing assessment form.
- C. Ask an advanced practice nurse to perform the assessment interview.
- D. Call for a mental health advocate to maintain the patient's rights.
Correct answer: A
Rationale: In this scenario, the patient is confused and unable to answer questions. When the patient is unable to provide information, it is important to use secondary sources such as family members. The nurse's best action is to document the patient's mental status and obtain additional assessment data from the family member. This approach will help gather relevant information about the patient's condition. Asking an advanced practice nurse to perform the assessment interview is not necessary as it is within the staff nurse's scope of practice. Calling for a mental health advocate is also unnecessary at this point as the priority is to assess the patient's condition and gather information from the family member.
5. A 70-year-old man has a blood pressure of 150/90 mm Hg in a lying position, 130/80 mm Hg in a sitting position, and 100/60 mm Hg in a standing position. How should the nurse evaluate these findings?
- A. These readings are a normal response and attributable to changes in the patient's position.
- B. The change in blood pressure readings is called orthostatic hypotension.
- C. The blood pressure reading in the lying position is within normal limits.
- D. The change in blood pressure readings is considered within normal limits for the patient's age.
Correct answer: B
Rationale: The correct answer is, 'The change in blood pressure readings is called orthostatic hypotension.' Orthostatic hypotension is defined as a drop in systolic pressure of �20 mm Hg or �10 mm Hg drop in diastolic pressure that occurs with a quick change to a standing position. This condition is common in individuals on prolonged bed rest, older adults, those with hypovolemia, or taking specific medications. The blood pressure readings provided in the question (150/90 mm Hg lying, 130/80 mm Hg sitting, and 100/60 mm Hg standing) demonstrate a significant change in blood pressure with position changes, which is indicative of orthostatic hypotension. Choices A, C, and D are incorrect because the readings do not indicate a normal response or blood pressure within normal limits for the patient's age; rather, they suggest the presence of orthostatic hypotension.
