Exam Cram NCLEX RN Practice Questions
1. The nurse is conducting a health fair for older adults. Which statement is true regarding vital sign measurements in aging adults?
- A. The pulse is easier to palpate due to the rigidity of the blood vessels.
- B. An increased respiratory rate and a shallower inspiratory phase are expected findings.
- C. A widened pulse pressure occurs from changes in the systolic and diastolic blood pressures.
- D. Changes in the body's temperature regulatory mechanism decrease the older adult's likelihood of developing a fever.
Correct answer: B
Rationale: Aging causes a decrease in vital capacity and decreased inspiratory reserve volume. As a result, the examiner may observe a shallower inspiratory phase and an increased respiratory rate in older adults. Contrary to common belief, the increased rigidity of arterial walls actually makes the pulse easier to palpate in aging adults. Pulse pressure is widened, not decreased, due to changes in systolic and diastolic blood pressures. Furthermore, changes in the body's temperature regulatory mechanism make older individuals less likely to develop a fever but more susceptible to hypothermia.
2. A patient in a clinic has been diagnosed with hepatitis A. What is the most likely route of transmission?
- A. Sexual contact with an infected partner
- B. Contaminated food
- C. Blood transfusion
- D. Illegal drug use
Correct answer: B
Rationale: The correct answer is contaminated food. Hepatitis A is primarily transmitted through the fecal-oral route, often through the ingestion of contaminated food or water. It is caused by the Hepatitis A virus (HAV), which is a single-stranded, positive-sense RNA virus. Sexual contact with an infected partner is more commonly associated with hepatitis B and C. Blood transfusion is a potential route for hepatitis B and C transmission due to bloodborne pathogens. Illegal drug use, particularly involving shared needles, is a common route for hepatitis C transmission.
3. You are working the 4 pm to 12 midnight evening shift. You are taking care of a group of patients. The supervising RN identifies 5 patients who get a medication at 'HS'. When will you give this medication?
- A. After the dinner meal
- B. Whenever requested
- C. At the patient's bedtime
- D. Before the end of the shift
Correct answer: C
Rationale: The correct answer is to give the medication at the patient's bedtime. 'HS' is a medical abbreviation that stands for 'hora somni,' which translates to 'at bedtime' or 'at the hours of sleep.' This timing ensures that the medication is administered appropriately to align with the patient's sleep schedule and maximize its effectiveness. Choices A, B, and D are incorrect because giving the medication after dinner, whenever requested, or before the end of the shift may not coincide with the intended purpose of the medication, potentially affecting its efficacy and patient outcomes.
4. 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.
5. The nurse is preparing to examine a 6-year-old child. Which action is most appropriate?
- A. The child is asked to undress from the waist up.
- B. The head is examined before the thorax, abdomen, and genitalia.
- C. The nurse should keep in mind that a child at this age will have a sense of modesty.
- D. Talking about the equipment being used is avoided to prevent increasing the child's anxiety.
Correct answer: C
Rationale: When examining a 6-year-old child, it is important to consider their sense of modesty. The child should undress themselves, leaving underpants on and using a gown or drape to maintain privacy. Additionally, a school-age child like a 6-year-old is curious about how equipment works, so it is beneficial to explain the purpose and function of the tools being used. The examination sequence should typically progress from the child's head to the toes to ensure a thorough assessment. Therefore, choices A, B, and D are incorrect as they do not align with the appropriate approach to examining a 6-year-old child.
