NCLEX RN Predictor Exam
1. Specific gravity in urinalysis:
- A. compares the concentration of urine to that of distilled water
- B. is useless when the patient is dehydrated
- C. can only be measured using a refractometer
- D. None of the above
Correct answer: A
Rationale: Specific gravity in urinalysis measures the concentration of solutes in urine compared to that of distilled water. This comparison helps in assessing the kidney's ability to concentrate urine properly. It is a valuable test even in dehydrated patients as it provides insights into renal function. Specific gravity can be measured using various methods, including a refractometer or reagent strips. Normal specific gravity readings of human urine typically range from 1.005 to 1.030. Choice A is correct as it accurately describes the purpose of specific gravity in urinalysis. Choices B and C are incorrect as specific gravity remains relevant in dehydrated patients and can be measured using different techniques, not solely a refractometer.
2. A patient is seen in the clinic for reports of "fainting episodes that started last week."? How would the nurse proceed with the examination?
- A. Blood pressure readings are taken in both arms and thighs.
- B. The patient is assisted to a lying position, and their blood pressure is taken.
- C. The patient's blood pressure is recorded in lying, sitting, and standing positions.
- D. The patient's blood pressure is recorded in lying and sitting positions; these numbers are then averaged to obtain a mean blood pressure.
Correct answer: C
Rationale: When a patient reports fainting episodes, it is crucial to assess for orthostatic hypotension. If the nurse suspects volume depletion, the patient has hypertension, is on antihypertensive medications, or has a history of fainting or syncope, blood pressure readings should be taken in three positions: lying, sitting, and standing. This assessment helps detect orthostatic hypotension, which can provide valuable information about the patient's condition. Taking blood pressure readings in multiple positions allows for a comprehensive evaluation of possible postural changes in blood pressure. Choices A, B, and D are incorrect because they do not cover the necessary positions to assess for orthostatic hypotension effectively.
3. On admission to the psychiatric unit, the client is trembling and appears fearful. The nurse's initial response should be to:
- A. Give the client orientation materials and review the unit rules and regulations.
- B. Introduce him/her and accompany the client to the client's room.
- C. Take the client to the day room and introduce him/her to the other clients.
- D. Ask the nursing assistant to get the client's vital signs and complete the admission search.
Correct answer: B
Rationale: Anxiety is triggered by change that threatens the individual's sense of security. In response to anxiety in clients, the nurse should remain calm, minimize stimuli, and move the client to a calmer, more secure/safe setting. The correct initial response is to introduce the client and accompany them to their room. This approach helps the client feel oriented, safe, and supported. Giving orientation materials or reviewing rules and regulations may overwhelm the client further. Taking the client to the day room and introducing them to other clients could increase anxiety by exposing them to unfamiliar faces. Asking the nursing assistant to get vital signs and complete admission tasks can wait until the client feels more settled and secure in their environment.
4. The nurse is preparing to perform a physical assessment. The correct action by the nurse is reflected by which statement?
- A. Performs the examination from both sides of the bed.
- B. Examines tender or painful areas last to help relieve the patient's anxiety.
- C. Follows a flexible examination sequence, considering the patient's age and condition.
- D. Organizes the assessment to ensure that the patient does not change positions too often.
Correct answer: D
Rationale: The nurse should organize the assessment to minimize the patient's need to change positions frequently, ensuring efficiency and comfort. It is essential to perform the examination from both sides of the bed to facilitate a comprehensive assessment. Examining tender or painful areas last can help reduce patient discomfort and anxiety. The examination sequence should be flexible, taking into account the patient's age, condition, and specific needs. This approach allows for a tailored and patient-centered assessment, optimizing the quality of care provided.
5. A 60-year-old patient has been treated for pneumonia for the past 6 weeks. The patient is seen today in the clinic for an unexplained weight loss of 10 pounds over the last 6 weeks. Which is an appropriate rationale for this patient's weight loss?
- A. Chronic diseases such as hypertension do not usually cause weight loss.
- B. Weight loss is more likely due to underlying medical conditions than unhealthy eating habits.
- C. Unexplained weight loss often accompanies short-term illnesses.
- D. Weight loss is not typically caused by mental health dysfunctions.
Correct answer: C
Rationale: Unexplained weight loss in a patient with pneumonia could indicate an underlying short-term illness or a chronic condition like endocrine disease, malignancy, depression, anorexia nervosa, or bulimia. Hypertension is not commonly associated with weight loss; it usually leads to weight gain due to fluid retention. Unhealthy eating habits are less likely to explain significant unexplained weight loss over a short period. Mental health dysfunctions can affect appetite but are not typically primary causes of significant unexplained weight loss.
